DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS
Referring to FIGS. 1-5, a patient care equipment support 20 has a plurality of equipment-receiving cavities 22 configured for receiving patient care equipment or modules 24. Examples of modules 24 that may be received in the equipment-receiving cavities 22 include: an infusion pump, a ventilator, a cardiac monitor, a pulse oximeter, a non-invasive blood pressure measuring device, a digital thermometer, a liquid oxygen module, a defibrillator, a respiratory rate measuring device, medical gas delivery equipment (such as an oxygen tank), intra-venous bags, and the like. Many patient care modules 24 connect via lines or tubes to a patient (not shown) supported on a hospital bed 40. As shown in FIG. 4, patient data received by one or more of the patient care modules 24 is displayed on a display screen 26 of a user interface device attached to the equipment support 20. In the illustrated embodiment, the display screen 26 is a flat panel touchscreen display. Some examples of patient data are blood pressure, temperature, pulse rate, respiratory rate, blood oxygen saturation level, patient weight, and the like. The equipment support 20 is configured to carry an oxygen tank 28 as shown in FIG. 4. Furthermore, equipment support 20 has a microcontroller 30, shown in phantom in FIG. 4, that is coupled to modules 24 and to display 26.
The equipment support 20 illustrated in FIGS. 1, 4 and 5 has three cavities 22, one each for a set of infusion pumps 32, a ventilator 34, and a patient monitor 36. One cavity 22 is shaped and sized for receiving four infusion pumps 32 arranged side by side therein. Two cavities 22 are shaped and sized for receiving the ventilator 34 and the patient monitor 36, respectively. The actual number of equipment-receiving cavities 22 depends on design considerations. Although the illustrated equipment support 20 has three cavities 22, the equipment support 20 may very well have more or less than three cavities 22. Illustratively, the equipment support 20 is in the form of a rectangular, box-shaped structure with the cavities 22 provided therein. However, the equipment support 20 may have any desired shape and, in some cases, the equipment support 20 may be in the form of a spine or a column (not shown) with pre-assigned spaces for the associated patient care modules 24.
The equipment support 20 is adapted to be transferable between a first device, such as the hospital bed 40, and a second device, such as an overhead support arm 42. As shown in FIGS. 4 and 5, the bed 40 includes a base frame 50, an upper frame 52 supported above the base frame 50, and an articulating deck 54 supported above the upper frame 52. A mattress 56 having a patient support surface 58 rests on the deck 54. The bed 40 includes a head end 60, a foot end 62, a first side 64, a second side 66, and a longitudinal axis 68. A set of jacks 70, 72 are interposed between the base frame 50 and the underside of the upper frame 52. A plurality of foot pedals 74 are coupled to the base frame 50 to operate the jacks 70, 72 to raise and lower the upper frame 52.
The deck 54 has longitudinally-spaced head, seat, thigh and foot sections. The seat section is fixed to the upper frame 52, and the head, thigh and foot sections are movable relative to each other and relative to the seat section. The base frame 50 is supported on four wheels 76. The outer periphery of the upper frame 52 defines a footprint when projected downwardly onto a floor 78. Two side rails 80 are coupled to the head section of the deck 54. Two side rails 82 are coupled to the upper frame 52 or to the foot section of the deck 54. A foot board 84 is coupled to the foot end 62 of the upper frame 52.
As shown in FIG. 1, a telescopic column 90 is coupled to a distal end 92 of the support arm 42 by a coupler 93. A proximal end 94 of the support arm 42 is supported by a ceiling or a wall of a hospital room 96. Alternatively, the proximal end 94 of the support arm 42 is supported by a support structure that extends upwardly from the floor 78 of the hospital room 96. The support arm 42 is pivotable about a substantially vertical axis 98 extending through the proximal end 94. In the illustrative embodiment, the support arm 42 is telescopic so that its distal end 92 telescopes horizontally relative to its proximal end 94. Non-telescopic arms are contemplated by this disclosure as well.
The telescopic column 90 has a lower portion 100 that telescopes vertically relative to an upper portion 102 under the power of an electric motor or other suitable driver housed in the upper portion 102. Illustratively, the motor is a linear actuator of the type commercially available from the Linak Company of Denmark. It is understood that drivers such as hydraulic cylinders, magnetic cylinders, pneumatic cylinders, and the like may be used in lieu of the motor to cause the vertical telescopic movement of the lower portion 100 of the column 90. The motor is actuated by a user control (not shown) positioned on the telescopic column 90 or a wall of the hospital room 96. Alternatively, the motor may be operated by a wired or wireless remote control.
The vertical telescoping movement of the column 90 permits the equipment support 20 to be lifted off the bed 40 and attached to the column 90. Additionally, such vertical telescoping movement of the column 90 permits the equipment support 20 to be detached from the column 90 and reattached to the bed 40. The pivoting movement of the support arm 42 about the vertical axis 98, the horizontal telescoping movement of the support arm 42, and the vertical telescoping movement of the column 90 allow the equipment support 20 to be positioned at any desirable location within a range of movements.
The bed 40, the support arm 42, and the column 90 merely illustrate the environment for the operation of the equipment support 20. It will be understood that the first device may very well be any one of the following: a stretcher, a surgery table, an ambulatory care chair, a wheeled carriage, a patient support, and the like. Likewise, the second device may very well be any one of the following: a cart, a stand, an arm, and the like.
In some embodiments, the equipment support 20 includes extendible support legs with floor-engaging wheels (such as the extendible support legs 350 with floor-engaging wheels 352 shown in FIGS. 6, 8, 9 and 12-19) which allow the equipment support 20 to be decoupled from the bed 40 or the column 90 and supported on the floor 78 for independent operation thereof. The support legs are configured to retract when the equipment support 20 is lifted off the floor 78 and attached to the bed 40 or the column 90 as shown in FIGS. 17-19.
As shown in FIG. 1, a support structure or ledge 110 extends outwardly from the head end 60 the base frame 50. Illustratively, the ledge 110 is spaced from the floor 78. At least a portion 112 of the ledge 110 extends outside the footprint of the upper frame 52. The equipment support 20 is detachably coupled to the ledge 110 outside the footprint of the upper frame 52. The width of the equipment support 20 is less than the width of the base frame 50. The width of the ledge 110 is less than the width of the equipment support 20. In some embodiments, the width of the equipment support 20 is equal to the width of the base frame 50. In some embodiments, the width of the ledge 110 is equal to the width of the equipment support 20.
When the equipment support 20 is coupled to structure 110 of the base frame 50, an upper portion 114 of the equipment support 20 is situated above the upper frame 52. Attachment of the equipment support 20 to the base frame 50, instead of the upper frame 52, allows the equipment support 20 to be taller than some prior art equipment supports which enables it to have an increased number of equipment-receiving cavities 22 for receiving multiple patient care modules 24.
The top 116 of the ledge 110 of the bed 40 has first power and data connectors 120 and a first mechanical connector 130. The bottom 104 of the lower portion 100 of the support column 90 has second power and data connectors 140 and a second mechanical connector 150. The equipment support 20 has third power and data connectors 122 and a third mechanical connector 132 coupled to the underside 124 of the equipment support 20. The equipment support 20 has fourth power and data connectors 142 and a fourth mechanical connector 152 coupled to the topside 144 of the equipment support 20.
The equipment support 20 is configured to be detachably coupled to the bed 40. As the equipment support 20 approaches the bed 40, the third mechanical connector 132 engages the first mechanical connector 130 before the third power and data connectors 122 engage the first power and data connectors 120 to align the third power and data connectors 122 with the first power and data connectors 120. As the engagement between the third mechanical connector 132 and the first mechanical connector 130 progresses, the third power and data connectors 122 couple to the first power and data connectors 120 to supply power to the equipment support 20 and to establish a communication link between the equipment support 20 and the bed 40. The engagement between the third mechanical connector 132 and the first mechanical connector 130 secures the equipment support 20 to the bed 40.
The equipment support 20 is configured to be detachably coupled to the column 90. As the column 90 approaches the equipment support 20, the second mechanical connector 150 engages the fourth mechanical connector 152 before the second power and data connectors 140 engage the fourth power and data connectors 142 to align the second power and data connectors 140 with the fourth power and data connectors 142. As the engagement between the second mechanical connector 150 and the fourth mechanical connector 152 progresses, the second power and data connectors 140 couple to the fourth power and data connectors 142 to supply power to the equipment support 20 and to establish a communication link between the equipment support 20 and the column 90. The engagement between the second mechanical connector 150 and the fourth mechanical connector 152 secures the equipment support 20 to the column 90.
The third and the fourth power and data connectors 122, 142 are arranged on the equipment support 20 so that the first and second power and data connectors 120, 140 can be coupled substantially simultaneously to the respective third and fourth power and data connectors 122, 142 before disconnection of either one of the first and second power and data connectors 120, 140 from the respective third and fourth power and data connectors 122, 142 to permit the equipment support 20 to be transferred between the bed 40 and the column 90 without a loss of power to the equipment support 20 or without a loss of communication link with the equipment support 20.
Likewise, the third and fourth mechanical connectors 132, 152 are arranged on the equipment support 20 so that the first and second mechanical connectors 130, 150 can be coupled substantially simultaneously to the respective third and fourth mechanical connectors 132, 152 before disconnection of either one of the first and second mechanical connectors 130, 150 from the respective third and fourth mechanical connectors 132, 152. This assures that the equipment support 20 is firmly secured to the bed 40 before it is released from the column 90, and firmly secured to the column 90 before it is released from the bed 40.
Each patient care module 24 has power and data connectors 160 which are configured to be coupled to associated power and data connectors 162 of the equipment support 20 to supply power to the patient care module 24 and to establish a communication link between the patient care module 24 and the equipment support 20 when the patient care module 24 is received in the associated equipment-receiving cavity 22 in the equipment support 20. Thus, each of the infusion pump 32, the ventilator 34 and the patient monitor 36 has power and data connectors 160 which are configured to be coupled to associated power and data connectors 162 of the equipment support 20. The power and data connectors 162 of the equipment support 20 are accessible for connection to the power and data connectors 160 of the patient care module 24 through respective openings (not shown) in an interior wall of the equipment support 20.
FIG. 2 is a schematic representation of the second and fourth power and data connectors 140, 142 and the second and fourth mechanical connectors 150, 152. The first and third power and data connectors 120, 122 are similar to the second and fourth power and data connectors 140, 142, and the first and third mechanical connectors 130, 132 are similar to the second and fourth mechanical connectors 150, 152. The second and fourth mechanical connectors 150, 152 serve to align the second and fourth power and data connectors 140 and to secure the equipment support 20 to the column 90. Likewise, the first and third mechanical connectors 130, 132 serve to align the first and third power and data connectors 120, 122 and to secure the equipment support 20 to the bed 40. FIG. 3 is a schematic representation of the power and data connectors 160, 162.
Locating pins (such as the pins 550, 572 shown in FIGS. 9 and 12) sized for cooperative mating engagement with associated sockets (such as the sockets 554, 578 shown in FIGS. 14 and 20) may be used for aligning the equipment support 20 with the bed 40 and the column 90. Latches (not shown) may be used for locking the equipment support 20 to the bed 40 or the column 90, as the case may be. Illustrative locating pins, sockets and latches are disclosed in 1) U.S. Pat. App. Pub. No. US2005/0000019, entitled “Patient Care Equipment Management System,” 2) PCT Pat. App. Pub. No. WO2005/037165, entitled “Patient Care Equipment Support Lock,” and 3) U.S. Pat. No. 4,795,122, all of which are hereby incorporated by reference herein.
In some embodiments, each one of first, second, third and fourth power and data connectors 120, 140, 122, 142 includes a first wired power coupler 170 to supply electrical power to the equipment support 20 and a second wireless data coupler 172 to establish a communication link between the equipment support 20 and the bed 40 or the support column 90, as the case may be. Each one of power and data connectors 160, 162 includes a first wired power coupler 180 to supply electrical power to the patient care module 24 and a second wireless data coupler 182 to establish a communication link between the patient care module 24 and the equipment support 20.
The wired couplers 170, 180 comprise electrical contacts. The wireless couplers 172, 182 comprise one or more of the following: a photoemitter, a photodetector, a photodiode, a radio frequency (RF) transmitter, an RF receiver, an RF transceiver, an infrared (IR) transmitter, an IR receiver, and an IR transceiver. Alternatively, wired data couplers may be used in lieu of the wireless data couplers 172, 182. Data from the patient care module 24 is wirelessly communicated to a computer network 190 of a healthcare system so that other computer devices connected to the computer network 190 have access to the data from the patient care module 24 when the patient care module 24 is received in the associated equipment-receiving cavity 22 in the equipment support 20 and the equipment support 20 is coupled to the bed 40 or the column 90.
The wireless communication between the patient care module 24 and the computer network 190 may be in accordance with any desired protocol, including the following protocols: IrDA, spread spectrum (including the Bluetooth protocol), RS232, TCP/IP, USB, and 802.11x. The wireless communication may use frequency modulation or by frequency modulated infrared (FMIR). In some embodiments, data includes control signals for the operation of the patient care modules 24, the display 26 or the microcontroller 30. The power and data connectors 120, 122, 140, 142, 160, 162 may be of the type illustrated in PCT Pat. App. Pub. No. WO2005/022692, entitled “Plug and Receptacle Having Wired and Wireless Coupling.”
In some embodiments, the power and data connectors 160, 162 of the patient care module 24 and the equipment support 20 are drawer connectors to facilitate blind mating when the patient care module 24 is inserted into the associated equipment-receiving cavity 22 of the equipment support 20. Such drawer connectors may be of the type illustrated in U.S. Pat. No. 4,664,456. In some embodiments, the power and data connector 162 of the equipment support 20 is a receptacle connector and the power and data connector 160 of the patient care module 24 is a plug connector.
As shown in FIG. 22, the display 26 is operable in several modes, either at the same time or at different times, when the equipment support 20 is coupled to the bed 40. In a first mode, the display 26 is operable to display patient data.

In a fifth mode, the display 26 is configured to display the operational status of the patient care modules 24 including information concerning one or more of the following: alarm status and the equipment settings.
The equipment support 20 has an on-board battery 200 for supplying power to the patient care modules 24, the display 26 and the microcontroller 30. Alternatively, the bed 40 and the support arm 42 each has a power source, such as, for example, a battery 202 or a converter to convert a line voltage to a low DC voltage, for supplying power to the patient care modules 24, the display 26 and the microcontroller 30 when the equipment support 20 is coupled to the bed 40 or the support arm 42. The equipment support 20 has conductors for electrically coupling the patient care modules 24, the display 26 and the microcontroller 30 to the power and data connectors 122, 142. Conductors may also extend between the display 26, the microcontroller 30 and the power and data connectors 162.
FIGS. 6-20 show another embodiment of a patient care equipment support 320. Portions of the equipment support 320 are substantially the same or similar as the like portions of the equipment support 20. The equipment support 320 has a plurality of equipment-receiving cavities 322 configured for receiving patient care modules 324. Many patient care modules 324 connect via lines or tubes to a patient (not shown) supported on a hospital bed 440. Patient data received by the patient care modules 324 is displayed on a display screen 326 of a user interface device attached to the equipment support 320. In the illustrated embodiment, the display screen 326 is a flat panel touchscreen display. The equipment support 320 includes an on-board microcontroller 692 (FIG. 8) coupled to the display 326.
As shown, for example, in FIGS. 6, 8, 9 and 12, the equipment support 320 is in the form of a rectangular, box-shaped main structure having a front wall 300, a back wall 302, a pair of side walls 304, 306, a top wall 308 and a bottom wall 310. In the illustrated embodiment, the equipment support 320 has eight cavities 322 that are accessible from the front wall 300 of the equipment support 320. As shown in FIGS. 6 and 8, seven of the eight cavities 322 are allocated to various module 324 and one cavity 322 is unallocated. Each cavity 322 is shaped and sized to receive one or more specific modules 324. In the illustrated embodiment, seven of the eight cavities 322 are allocated as follows: 1) a plurality of mini modules 328 (such as pulse oximeter, non-invasive blood pressure measuring module, and the like), 2) a first dual channel IV pump module 330, 3) a second dual channel IV pump module 332, 4) a portable suction module 334, 5) a ventilator module 336, 6) a liquid oxygen module 338, and 7) a battery module 340. The unallocated cavity 322 may be configured to receive any suitable module 324, such as, for example, a cardiac monitor, an apnea monitor, a respiratory rate measuring module, and the like.
As shown, for example, in FIGS. 6 and 8, the top wall 308 of the equipment support 320 comprises a central recess 312 disposed between two raised shelf portions 314. A digital thermometer 342 is coupled to one of the two shelf portions 314 near the left side wall 304. An IV pole 344 is coupled to the other of the two shelf portions 314 near the right side wall 306. The IV pole 344 has a cantilevered arm 346 for supporting one or more IV bags 348.
Although the illustrated equipment support 320 has eight cavities 322, the equipment support 320 may very well have more or less than eight cavities 322. Likewise, although a specific allocation of the eight cavities 322 is made in the illustrated embodiment, a different allocation of the eight cavities 322 may very well be made. Although the illustrated equipment support 320 has a rectangular, box-shaped main structure, it may very well have a main structure of any desired shape. In some cases, the main structure of the equipment support 320 may be in the form of a spine or a column (not shown) with pre-assigned spaces for specific patient care modules 24.
As shown in FIG. 19, the equipment support 320 is adapted to be transferable between a first device, such as the hospital bed 440, and a second device, such as an overhead support arm 442. In the illustrated example, the bed 440 and the support arm 442 merely illustrate the environment for the operation of the equipment support 320. It will be understood that the first device may very well be any one of the following: a stretcher, a surgery table, an ambulatory care chair, a wheeled carriage, a patient support, and the like. Likewise, the second device may very well be any one of the following: a cart, a stand, an arm, and the like.
As shown, for example, in FIGS. 6, 8, 9 and 12, the equipment support 320 includes a pair of downwardly-extending support legs 350 with floor-engaging wheels 352 which allow the equipment support 320 to be decoupled from the bed 440 or the support arm 442 and lowered onto the floor 478 for independent operation thereof. The bottom wall 310 of the equipment support 320 comprises a central downwardly-projecting portion 316 disposed between two vertically-extending recesses 318 as shown in FIGS. 9 and 12. The support legs 350 extend downwardly from respective downwardly-facing surfaces of the recesses 318. The support legs 350 are configured to retract into the associated recesses 318 when the equipment support 320 is lifted off the floor 478 and coupled to the bed 440 as shown in FIGS. 17, 18 or to the support arm 442 as shown in FIG. 19.
Each support leg 350 includes a pair of wheel-supporting members 354. As shown, for example, in FIG. 9, the wheels 352 are coupled to distal ends 356 of the members 354. Proximal ends 358 of the members 354 are coupled to the associated support leg 350 to pivot between an extended position shown in FIGS. 6, 8, 9 and 12-15 where the members 354 extend generally perpendicularly to a longitudinal axis 360 of the equipment support 320 and a retracted position shown in FIGS. 17-19 where the members 354 extend generally parallel to the longitudinal axis 360 of the equipment support 320. As shown in FIGS. 17-19, when retracted, the wheel-supporting members 354 are withdrawn within the respective leg-receiving recesses 318 of the equipment support 320 so that the wheel-supporting members 354 and the associated wheels 352 are within a footprint of the equipment support 320.
The support legs 350 are telescopic. As shown, for example, in FIG. 12, each support leg 350 includes an upper portion 364 and a lower portion 366. Two vertically-extending leg-receiving spaces 368 are formed on the opposite sides 304, 306 of the equipment support 320 above the recesses 318. The upper portions 364 of the support legs 350 retract into the associated leg-receiving spaces 368 shown in FIG. 12 when the support legs 350 are moved to their respective storage positions as shown, for example, in FIGS. 17-19. The upper portions 364 of the support legs 350 extend out of the associated leg-receiving spaces 368 when the support legs 350 are moved to their respective use positions as shown, for example, in FIGS. 6, 8, 9 and 12-15. The lower portions 366 of the support legs 350 are less thick than the respective upper portions 364 (as shown in FIG. 12) to create two opposite wheel-supporting-member-receiving recesses 370 (shown in FIG. 17) into which the pivotable wheel-supporting members 354 are received with their associated wheels 352 as shown in FIG. 17 when the support legs 350 are moved to their respective storage positions.
As the upper portions 364 of the support legs 350 telescope into the respective leg-receiving spaces 368 in the equipment support 320 in the manner shown in FIGS. 15-17, the wheel-supporting members 354 and the associated wheels 352 simultaneously pivot upwardly into their storage positions in the respective wheel-supporting member-receiving recesses 370 formed in the support legs 350. Likewise, as the upper portions 364 of the support legs 350 telescope out the associated leg-receiving spaces 368, the wheel-supporting members 354 and the associated wheels 352 simultaneously pivot downwardly to their respective use positions as shown, for example, in FIGS. 6, 8, 9 and 12-15.
In the illustrated embodiment, one or more electric motors (not shown) housed in equipment support 320 power the telescopic movement of the support legs 350 and the pivoting movement of the wheel-supporting members 354. Each electric motor may be a linear actuator of the type commercially available from the Linak Company of Denmark. It is understood that drivers such as hydraulic cylinders, magnetic cylinders, pneumatic cylinders, and the like may be used in lieu of the electric motors to cause the telescopic movement of the support legs 350 and the pivoting movement of the wheel-supporting members 354. The motors are actuated by associated controls (not shown) positioned on the main structure of the equipment support 320 or by a wired or wireless remote control.
Such vertical telescoping movement of the support legs 350 and the associated pivoting movement of the wheel-supporting members 354 permit the equipment support 320 to be decoupled from the bed 440 or the support arm 442 and supported on the floor 478 as shown in FIGS. 6, 8, 9 and 12-15. Also, such vertical telescoping movement of the support legs 350 and the associated pivoting movement of the wheel-supporting members 354 permit the equipment support 320 to be lifted off the floor 478 and reattached to the bed 440 as shown in FIGS. 16-18, or reattached to the arm 442 as shown in FIG. 19.
As shown in FIGS. 13-19, the bed 440 includes a base frame 450, an upper frame 452 supported above the base frame 450, and an articulating deck 454 supported above the upper frame 452. A mattress 456 having a patient support surface 458 rests on the deck 454. The bed 440 includes a head end 460, a foot end 462, a first side 464, a second side 466, and a longitudinal axis 468. A set of pivotable lift arms 470, 472 are interposed between the base frame 450 and the underside of the upper frame 542. A plurality of foot pedals (not shown) are coupled to the base frame 450 to operate the pivotable lift arms 470, 472 to raise and lower the upper frame 452.
The deck 454 has longitudinally-spaced head, seat, thigh and foot sections. The seat section is fixed to the upper frame 452, and the head, thigh and foot sections are movable relative to each other and relative to the seat section. The base frame 450 is supported on four wheels 476. The outer periphery of the upper frame 452 defines a footprint when projected downwardly onto a floor 478. Two side rails 480 are coupled to the head section of the deck 454. Two side rails 482 are coupled to the upper frame 452 or to the foot section of the deck 754.
As shown in FIGS. 13-19, a first relatively wide ledge 484 extends outwardly in a cantilevered manner from the head end 460 of the base frame 450. The ledge 484 is spaced from the floor 478. In the illustrated example, the width of the ledge 484 is less than the width of the base frame 450. A pair of laterally-spaced frame members 486 shown, for example, in FIG. 13 extend outwardly from the head end 460 of the ledge 484. Each frame member 486 has a first portion 488 that extends horizontally outwardly from the ledge 484 and a second portion 490 that extends vertically upwardly from a distal end of the associated first portion 488. A cross plate 492 extends between the upper regions 494 of the second portions 490 of the frame members 486 as shown, for example, in FIG. 13.
A push bar 496 extends vertically upwardly from a free end of each second portion 490 as shown, for example, in FIG. 13. Each push bar 496 has an outwardly-turned handle post 498 that may be grasped by a caregiver for moving the bed 440. In the illustrated embodiment, the handle posts 498 are enclosed in respective sleeves made from soft material, such as rubber. The push bars 496 and the associated handles 498 are located forward of a footprint of the upper frame 452 of the bed 440.
Still referring to FIG. 13, a second relatively narrow ledge 500 extends outwardly in a cantilevered manner from the head end 460 of the first relatively wide ledge 484. The ledge 500 is spaced from the floor 478. The ledge 500 is positioned intermediate of the push bars 496. At least a forward portion 502 of the ledge 500 extends outside the footprint of the upper frame 452. The equipment support 320 is detachably coupled to the forward portion 502 as shown in FIGS. 17, 18. In the illustrated example, the width of the equipment support 320 is less than the inner spacing between the vertically-extending portions 490 of the frame members 486 as shown in FIG. 13. In some embodiments, the width of the equipment support 320 is equal to the width of the base frame 450. In the illustrated example, the width of the ledge 500 is less than the inner spacing between the downwardly-extending support legs 350 of the equipment support 320. In some embodiments, the width of the ledge 500 is equal to the width of the equipment support 320.
When the equipment support 320 is coupled to the base frame 450 of the bed 440, an upper portion 504 of the equipment support 320 is situated above the upper frame 452 as shown in FIGS. 17, 18. Attachment of the equipment support 320 to the base frame 450, instead of the upper frame 452 of the bed 440, allows the equipment support 320 to be taller so that it can have multiple equipment-receiving cavities 322 for receiving multiple patient care modules 324.
As shown in FIG. 19, a telescopic column 520 is coupled to a distal end 522 of the support arm 442 by a coupler 524. A proximal end 526 of the support arm 442 is supported by a support structure 528 that extends upwardly from the floor 478 of a hospital room 530 in the illustrated embodiment. Alternatively, the proximal end 526 of the support arm 442 may be supported by a ceiling or a wall of the hospital room 530. The support arm 442 is pivotable about a vertical axis 532 extending through the proximal end 528. The illustrative support arm 442 is telescopic so that its distal end 522 telescopes horizontally relative to its proximal end 526.
The column 520 has a lower portion 534 that telescopes vertically relative to an upper portion 536 under the power of an electric motor housed in the upper portion 536. Illustratively, the motor is a linear actuator of the type commercially available from the Linak Company of Denmark. It is understood that drivers such as hydraulic cylinders, magnetic cylinders, pneumatic cylinders, and the like may be used in lieu of the motor to cause vertical telescopic movement of the lower portion 534 of the column 520 relative to the upper portion 536. The motor is actuated by a control (not shown) positioned on the lower portion 534 of the column 520. Alternatively, the motor may be operated by a wired or wireless remote control or a control positioned on a wall of the hospital room 530. The equipment support 320 is detachably coupled to the lower portion 538 of the column 520 as shown in FIGS. 19, 20.
The vertical telescopic movement of the column 520 permits the equipment support 320 to be lifted off the bed 440 and lowered onto the floor 478 of the hospital room 530 as shown in FIGS. 6, 8, 9 and 12-14 for standalone operation thereof. Also, such telescopic movement of the column 520 permits the equipment support 320 to be lifted off the floor 478 and reattached to the bed 440 as shown in FIGS. 17, 18 or to the support arm 442 as shown in FIG. 19. The pivoting movement of the support arm 442 about the vertical axis 532, the horizontal telescoping movement of the support arm 442, and the vertical telescoping movement of the column 520 allow the equipment support 320 to be positioned at any desirable location within a range of movements. As previously indicated, the bed 440, the support arm 442, and the column 520 merely illustrate the environment for the operation of the equipment support 320.
As shown, for example, in FIG. 9, a pair of laterally-spaced coupling or locating pins 550 extend downwardly from the downwardly-facing wall 552 of the equipment support 320. The downwardly-extending pins 550 are configured for reception in a complementary pair of upwardly-opening sockets 554 of the hospital bed 440 as shown, for example, in FIG. 13. The upwardly-opening sockets 554 are received in respective socket-receiving openings formed in a mounting block 558. The mounting block 558 is secured to the upwardly-facing wall 560 of the forward portion 502 of the ledge 500 of the hospital bed 440. The lateral spacing between the upwardly-opening sockets 554 is the same as the lateral spacing between the downwardly-extending pins 550.
As shown in FIG. 12, a mounting block-receiving cavity or pocket 570 is formed in the upper region of the back wall 302 of the equipment support 320. A pair of laterally-spaced coupling or locating pins 572 extend downwardly beyond a downwardly-facing wall 574 of the cavity 570. The downwardly-extending pins 572 are spaced outwardly from a back wall 576 of the cavity 570. The downwardly-extending pins 572 are configured for reception in a complementary pair of upwardly-opening sockets 578 shown in FIG. 20. The upwardly-opening sockets 578 are received in respective socket-receiving openings formed in a mounting block 582 of the column 520. The mounting block 582 has a first portion 584 that extends outwardly in a cantilevered fashion from a lower region 538 of the lower portion 534 of the column 520. The mounting block 582 has a second lip portion 586 that extends upwardly from a distal end of the first portion 584. The socket-receiving openings are formed in the upwardly-extending lip portion 586 of the mounting block 582.
The lateral spacing between the upwardly-opening sockets 578 of the column 520 is the same as the lateral spacing between the downwardly-extending coupling pins 572 of the equipment support 320. To attach the equipment support 320 to the column 520, the upwardly-extending lip portion 586 of the mounting block 582 is inserted into the mounting block-receiving cavity 570 and the lower portion 534 of the column 520 is raised so that the downwardly-extending pins 572 of the equipment support 320 are received in the upwardly-opening sockets 578. The lip portion 586 of the mounting block 582 is sized and shaped to facilitate reception thereof in the cavity 570 even when the alignment between the two is slightly off as the lip portion 586 of the column 520 is inserted into mounting block-receiving cavity 570. Thus, the width and the thickness of the second portion 586 of the mounting block 582 is slightly less than the width and the thickness of the cavity 570, respectively. The second portion 586 of the mounting block 582 tapers gently from, wide to narrow, in a forward direction away from the column 520.
Referring to FIG. 9, a power connector 590 (shown in FIG. 10) and a data connector 592 (shown in FIG. 11) are coupled to the downwardly-facing wall 552 of the equipment support 320 between the coupling pins 550. A complementary power connector 594 (shown in FIG. 10) and a complementary data connector 596 (shown in FIG. 11) are coupled to the mounting block 558 of the bed 440 between the upwardly-opening sockets 554. The power and data connectors 590, 592 of the equipment support 320 are configured to be coupled to the associated power and data connectors 594, 596 of the bed 440 when the equipment support 320 is coupled to the bed 440 as shown, for example, in FIGS. 15-18.
As shown in FIG. 12, a power connector 600 and a data connector 602 are coupled to the downwardly-facing wall 574 of the equipment support 320 between the downwardly-extending coupling pins 572. As shown in FIG. 20, a complementary power connector 604 and a complementary data connector 606 are coupled to the mounting block 582 of the column 520 between the upwardly-opening sockets 578. The power and data connectors 600, 602 of the equipment support 320 are configured to be coupled to the associated power and data connectors 604, 606 of the column 520 when the equipment support 320 is coupled to the column 520 as shown in FIG. 19.
In the illustrated embodiment, the two power connectors 590, 600, shown in FIGS. 9 and 12 respectively, coupled to the equipment support 320 are identical. Likewise, the power connectors 594, 604 coupled to the bed 440 and the column 520 are identical. Also, the two data connectors 592, 602, shown in FIGS. 9 and 12 respectively, coupled to the equipment support 320 are identical in the illustrated embodiment. Likewise, the data connectors 596, 606 coupled to the bed 440 and the column 520 are identical.
Illustratively, as shown in FIG. 21, the coupling pins 550, 572 each has a frustoconical tapered end portion 610 for facilitating engagement with a complementary upwardly-facing frustoconical opening 612 in the associated sockets 554, 578 even when the alignment between the two is slightly off as the equipment support 320 is lowered to engage the bed 440 or the lower portion 534 of the column 520 is raised to engage the equipment support 320. The tapered end portions 610 of the coupling pins 550, 572 vary in diameter from wide to narrow in a downward direction. It should be understood, however, that other approaches by which the bed 440 or the column 520 engage and support the equipment support 320 are within the scope of this disclosure. For example, the bed 440 could have a pair of upwardly-extending posts (not shown), while the equipment support 320 could have a pair of downwardly-opening sockets (not shown). The sockets 554, 578 are illustratively made from a different material than steel, such as brass or aluminum bronze, to allow the coupling pins 550, 572 of the equipment support 320 to be received in the associated sockets 554, 578 without galling the mating surfaces.
To attach the equipment support 320 to the bed 440, the equipment support 320 lowered onto the bed 440. The downwardly-extending coupling pins 550 of the equipment support 320 engage the associated upwardly-opening sockets 554 of the bed 440 before the power and data connectors 590, 592 of the equipment support 320 engage the respective power and data connectors 594, 596 of the bed 440 to align the power and data connectors 590, 592 of the equipment support 320 with the respective power and data connectors 594, 596 of the bed 440. As the engagement between the coupling pins 550 and the associated sockets 554 progresses, the power and data connectors 590, 592 couple to the respective power and data connectors 594, 596 to supply power to the equipment support 320 and to establish a communication link between the equipment support 320 and the bed 440. Also, the engagement between the coupling pins 550 and the sockets 554 mechanically secures the equipment support 320 to the bed 440.
To attach the equipment support 320 to the column 520, the column 520 approaches the back wall 302 of the equipment support 320. The upwardly-extending lip portion 586 of the mounting block 582 is inserted into the mounting block-receiving cavity 570 and the lower portion of 534 of the column 520 is then raised. The downwardly-extending coupling pins 572 of the equipment support 320 engage the associated upwardly-opening sockets 578 of the column 520 before the power and data connectors 600, 602 of the equipment support 320 engage the respective power and data connectors 604, 606 of the column 520 to align the power and data connectors 600, 602 of the equipment support 320 with the respective power and data connectors 604, 606 of the column 520. As the engagement between the coupling pins 572 and the associated sockets 578 progresses, the power and data connectors 600, 602 couple to the respective power and data connectors 604, 606 to supply power to the equipment support 320 and to establish a communication link between the equipment support 320 and the column 520. Also, the engagement between the coupling pins 572 and the sockets 578 mechanically secures the equipment support 320 to the column 520.
The power and data connectors 590, 592 and 600, 602 are arranged on the equipment support 320 so that the power and data connectors 594, 596 of the bed 440 and the power and data connectors 604, 606 of the column 520 can be coupled substantially simultaneously to the respective power and data connectors 590, 592 and 600, 602 of the equipment support 320 before disconnection of either one of the power and data connectors 594, 596 of the bed 440 and the power and data connectors 604, 606 of the column 520 from the respective power and data connectors 590, 592 and 600, 602 of the equipment support 320 to permit the equipment support 320 to be transferred between the bed 440 and the column 520 without a loss of power to the equipment support 320 or without a loss of communication link with the equipment support 320.
Likewise, the coupling pins 550, 572 are arranged on the equipment support 320 so that the sockets 554 of the bed 440 and the sockets 578 of the column 520 can be coupled substantially simultaneously to the respective coupling pins 550, 572 before disconnection of either one of the sockets 554 of the bed 440 and the sockets 578 of the column 520 from the respective coupling pins 550, 572. This assures that the equipment support 320 is firmly secured to the bed 440 before it is released from the column 520, and firmly secured to the column 520 before it is released from the bed 440.
Referring to FIG. 7, a power connector 660 and a data connector 662 are coupled to an equipment-support-facing wall of each patient care module 324. A complementary power connector 664 and a complementary data connector 666, also shown in FIG. 7, are coupled to a patient-care-module-facing wall of an associated equipment-receiving cavity 322 in the equipment support 320. The power and data connectors 660, 662 of each patient care module 324 are configured to be coupled to the respective power and data connectors 664, 666 in the associated equipment-receiving cavity 322 in the equipment support 320 to supply power to the module 324 and to establish a communication link between the module 324 and the equipment support 320 when the module 324 is received in the associated equipment-receiving cavity 322 in the equipment support 320 as shown in FIGS. 8, and 13-19.
Thus, each of the mini modules 328, the IV pump modules 330, 332, the suction module 334, the ventilator module 336, and the liquid oxygen module 338 have power and data connectors 660, 662 which are configured to be coupled to associated power and data connectors 664, 666 of the equipment support 320. The power and data connectors 664, 666 of the equipment support 320 are accessible for connection to the power and data connectors 660, 662 of the modules 324 through respective openings (not shown) in an interior wall of the equipment support 320.
In the illustrated embodiment, the data connector 596 of the bed 440, the data connector 606 of the column 520 and the two data connectors 592, 602 of the equipment support 320 each comprise a wireless coupler. The wireless couplers 592, 596, 602, 606 each comprise one or more of the following: a photoemitter, a photodetector, a photodiode, a radio frequency (RF) transmitter, an RF receiver, an RF transceiver, an infrared (IR) transmitter, an IR receiver, and an IR transceiver. Alternatively, wired data couplers may be used in lieu of the wireless data couplers 592, 596, 602, 606. Data from the patient care module 324 is wirelessly communicated to a computer network 690 of a healthcare system so that other computer devices connected to the computer network 690 have access to the data from the patient care module 324 when the patient care module 324 is received in the associated equipment-receiving cavity 322 in the equipment support 320 and the equipment support 320 is coupled to the bed 440 or the support arm 442.

FIGS. 23 and 24 show a hospital bed 740 similar to the bed 440 shown in FIGS. 13-19, except that the bed 740 has a swivelable forwardly-extending support structure 800 for supporting the equipment support 320 so that the equipment support 320 can be swiveled to either side of the bed 740 as needed. Where appropriate, like reference numerals are used to denote portions of the bed 740 that are substantially similar to like portions of the bed 440. Thus, the bed 740 includes a base frame 750, an upper frame 752 supported above the base frame 750, and an articulating deck 754 supported above the upper frame 752. Two side rails 780 are coupled to the head section of the deck 754. Two side rails 782 are coupled to the upper frame 752 or to the foot section of the deck 754. A pair of push bars 796 are coupled to the upper frame 752 near the head end 760. Each push bar 796 has a forwardly and upwardly-extending portion 797 and an inwardly-extending portion 798 that forms a handle post.
A relatively wide ledge 784 extends forwardly in a cantilevered manner from the head end 760 of the base frame 750. In the illustrated example, the ledge 784 has an arcuate forwardly-facing wall which forms an arc of a circle having a center located on a vertical axis 748. In the illustrated example, the width of the ledge 784 is less than the width of the base frame 750. A relatively narrow support structure 800 extends forwardly in a cantilevered manner from the head end 760 of the relatively wide ledge 784. In the illustrated example, the support structure 800 is coupled to the underside of the ledge 784 for pivoting movement about the vertical axis 748. Both the ledge 784 and the swivelable support structure 800 are spaced from the floor 778 of the hospital room. At least a forward portion 802 of the swivelable support structure 800 extends outside the footprint of the upper frame 752. As shown in FIGS. 23, 24, the equipment support 320 is detachably coupled to the forward portion 802 of the swivelable support structure 800 in a manner similar to the manner in which the equipment support 320 is detachably coupled to the forward portion 502 of the relatively narrow ledge 500 as shown, for example, in FIGS. 17 and 18.
In the illustrated example, the support structure 800 is telescopic so that, when attached, the equipment support 320 can move between a retracted position closer to the bed 740 where the equipment support 320 is located between the handle posts 798 as shown in solid in FIG. 23 and an extended position further spaced from the bed 740 where the equipment support 320 is located forwardly of the handle posts 798 as shown in phantom in FIG. 23 so that the equipment support 320 can clear the handle posts 798 when it is swiveled to a side of the bed 740. In such embodiments, to move the equipment support 320 to a side of the bed 740, the equipment support 320 is first moved to the extended position forwardly of the handle posts 798 and then moved to one of the two sides of the bed 740 as desired. The telescopic support structure 800 includes a first segment 810 and a second segment 812 that telescopes horizontally into and out of the first segment 810. In some alternate embodiments, the support structure 800 is not telescopic, but it is dimensioned such that the equipment support 320, when attached to the support structure 800, is positioned forwardly of the handle posts 798 so that it can swivel from side to side without interference from the handle posts 798.
In the illustrated example, the width of the equipment support 320 is less than the inner spacing between the handle posts 798. In some embodiments, the width of the equipment support 320 is equal to the width of the base frame 750. In the illustrated example, the width of the swivelable support structure 800 is less than the inner spacing between the downwardly-extending support legs 350 of the equipment support 320. In some embodiments, the width of the support structure 800 is equal to the width of the equipment support 320. When the equipment support 320 is supported by the base frame 750 of the bed 740, an upper portion 804 of the equipment support 320 is situated above the upper frame 752 as shown in FIGS. 23, 24. Attachment of the equipment support 320 to the base frame 750, instead of the upper frame 752, allows the equipment support 320 to be taller so that it can have multiple equipment-receiving cavities 322 for receiving multiple patient care modules 324.
