The The present invention relates generally to a method of control the adjustment of support parts a basic structure for a bed or the like. In particular, the present invention relates Invention a control method for the operation, in particular putting down a back carrier part and a leg support part a basic structure for a bed or the like, wherein the back support member after the raising in the largest angle of inclination is tilted and the back support part is provided to the back area of a patient lying on it, while the leg support part intended to lift the knees of a patient lying on it.
Of the As used in this specification, "bed or the like" is understood to mean that he also for mobile couches, operating room stretchers and other structures horizontal surface applies, on which patients can lie.
Lots novel beds and the like are provided with a basic structure, the one back carrier part for carrying and lifting the back a patient lying on it and a leg support part for lifting the knees of a patient lying on it.
Lots Examples of such beds or the like are, for example, the U.S. Patents 5,469,591; 5,448,789 and 5,388,290.
So has, for example, the bed described in U.S. Patent 5,469,591 Back part to the Lifting the back area a patient and a leg support part for lifting the knee area of the patient. There are also others Parts before present. There are provided lifting arms, which are the lower sides of the back carrier part or the leg support part touch.
Everyone this lifting arm has a roller at the top and is pivoting rotatable so that the lift arms of drive devices such as e.g. Engines actuated and can be rotated.
at this arrangement, the lifting arm of the back support member is pivotally rotated, so that the role of the back carrier part lift in a tilting, rotating motion to an inclined position can and while doing the back raises the patient so that he is placed in a more upright position can be.
If the back carrier part lifted and tilted in this way will the lifting arm of the leg support part pivoting turned so that the roller pivoting the leg support part in pivoting Can lift movement into an inclined position while preventing that the patient slips forward, if only the back carrier part would be raised.
In a case in which the back of the patient lying on the bed is raised to the patient In a more upright position, the body slips Patient lifting the backrest part gradually forward, because the back of the patient from the back support part pushed forward becomes. This shifts the point at which the body of the Patients can be easily bent, from the pivot point of the back support part into the lumbar and abdominal region, with the back part being raised can not be easily bent and the patient feels discomfort.
in the In contrast, when lifting the leg support part with raised back part on the body part of the patient, who is above the inclined leg support part is located, i. on the thigh region of the patient, from the back support part on the back the patient exerted a force be that forward suppressed. This can prevent the body of the patient from slipping and the patient feels discomfort when only the back of the Patient with the back support part is raised.
It is known to lift the leg support portion when the back support portion of a base structure of a bed or the like is raised. The conventional methods for lifting the leg support part when lifting the back support part include, for example, the following methods:
In the first example, the driving device for lifting the back support member and the leg support member are operated independently. The lying on the bed patient or a caregiver can switch on and off the corresponding drive device simultaneously or alternatively, for example, with switches to bring the back support member and the leg support member in the desired position.
in the second example is an ordinary engine to the drive device of the back support member and the leg support member with a gear device such as e.g. an intermediate link so too actuate, in that the drive device of the back support part and the leg support part can be operated in a mechanically interlocking manner to the back support member and the leg support part to bring in predetermined positions.
However, these conventional methods have the following problems:
In the method listed first above, the patient or caregiver must drive the corresponding drive device of the back support member and the patient Operate leg support parts simultaneously or alternatively. This process is very complicated and cumbersome, and you have to get used to the operation. Furthermore, it is difficult to always track the optimal lifting heights for the back support member and the leg support member.
in the second above Example are the lifting stages due to the interlocking device for the Back support portion and the leg support part inevitably simple and impossible to change, and it is difficult to prevent the patient's body from slipping and that the patient feels discomfort because of the support parts when lifting, press on the lumbar and abdominal region.
In addition, back carrier part and leg support part not independent be operated from each other.
Even though according to the state of the art measures be taken to prevent the body of the patient forward slips and that the patient feels discomfort when the back part of the back is raised as described above, nothing is done to prevent the patient's body from slipping, if the back carrier part is lowered again. For this reason, the caregiver, after all carrier parts have been put down and lie flat again, the patient, his body slipped forward is to bring back to the original position on the bed.
The The present invention seeks to do this in the prior art to solve the problem that the basic structure for a bed or the like a back support member for lifting the back portion a patient lying on it and a leg support part for lifting the knees of a patient lying on it, and that the corresponding support parts with each for they are provided lifting devices, with an effective It prevents the body of the patient from slipping and that the patient feels an uncomfortable pressure, the Causing discomfort when the back carrier part pivoting in a tilted position is rotated.
If all carrier parts, after being turned and raised in a tilted position were put back down to flat in non-raised position can lie as well effectively prevents the patient's body from slipping.
According to one first embodiment The present invention provides a method with which the adjustment of the support parts the basic structure for a bed or the like is regulated, the basic structure a back carrier part for adjusting the back region a patient lying thereon and a leg support part for adjusting the knees of the patient lying on it, and the corresponding support parts with each for they provided lifting devices can be adjusted, thereby characterized in that when the back carrier part begins in a raised position with the largest inclination angle, first the Lifting the leg support part causes the hang-up part to be lowered appropriately later Timing is at the time when the lifting is initiated; after that, the leg support part is lowered continued while the leg support part in a predetermined highest Position raised and then put down until he is his reached lowest limit position and flat in not raised Position at a later date than at the time, on which the back carrier part down to its lowest limit position and flat is in a non-raised position.
at this method, the leg support member remains in the raised position, while the back carrier part swiveling down. In this way supports the Leg support portion the location of the abdominal region of the patient lying on the bed the leg support part remains in the raised position. This will prevent that the patient lying on it slides forward in this state, too if the back carrier part is put down.
Would that be Lifting the leg support part uncontrolled continued when the back support member is lowered, then would the knee area of the patient lying on it in a position raised, the higher as necessary, which would lead to that the patient feels discomfort. In addition, the between back part would and leg support part emerging angles gradually lose weight, and that would cause that the abdominal region of the patient gradually between the back support part and leg support part being squeezed together, causing the patient pressure in the abdominal region feel would.
However, according to a first aspect of the present invention, the lifting of the leg support member is not continued unregulated, but limited to a predetermined highest position. Therefore, the angle formed between the back support member and the leg support member can not become smaller than intended. This prevents the knees of the patient lying thereon from being raised to a position which is higher than necessary, thereby preventing the abdominal region of the patient from being pressed together and preventing the patient from being affected hagen feels.
advantageously, is the time at which to put down the backrest part starts, later as the time at which the lifting of the leg support member is caused, and / or the time at which the leg support part the highest Position achieved is calculated in relation to the time since Time has elapsed at which the lifting of the leg support part starts.
If the performance the drive sources for actuation the lifting device of the leg support part and the back carrier part is sufficiently larger as the force required to lift the support members onto which the weight of the patient acts, or if the weight is constant is, then there is a direct correlation between the after actuation of a Lifting device elapsed time and the position of the corresponding raised support member. If so, the elapsed time is a simple one Method to coordinate the lifting of the support members of the bed structure regulate.
Preferably will be the point in time at which to put down the backrest part later arranged Must be considered at the time when lifting the leg support part is caused by a positioning of the leg support part certainly.
According to one second aspect of the present The invention will provide a method for controlling the adjustment of carrier parts a basic structure for a bed or the like presented, wherein the basic structure a Back support portion for adjusting the backrest part a patient lying on it and a leg support part for adjusting the knees of the patient lying thereon, the corresponding support parts can be lifted with a lifting device, characterized that if the carrier parts lie flat in a non-raised position, first lifting the leg support and that at a time that occurs reasonably later as the timing at which the lifting is caused, the lifting of the back carrier part is initiated; after that, the lowering of the back support part is continued, while the leg support part in a predetermined highest Position raised and then put down until he is his reaches low limit position and lies flat in non-raised position, at a time that is reasonably later than the time on which the back carrier part reached a raised position with the largest inclination angle.
below Become embodiments of the present invention by way of example only and with reference to the attached Drawings described, wherein
1 to 7 Figure 11 shows side views with cross sections of the entire shape of a base structure in different phases of the lifting operation, the method by which the lifting of the support parts according to the present invention is applied to a basic structure of a bed;
8th Fig. 3 is a diagram exemplifying how the inclination angles of the back support member and the leg support member change when the method of controlling the lift of the support members is used in the present invention.
The illustrated bed consists of a back carrier part 1a for lifting a patient lying thereon and a leg support part 1b for lifting the knees of a patient lying thereon, and a lower leg support part 1c which corresponds to the lower leg area of the patient lying thereon. The back carrier part 1a , the leg support part 1b and the lower leg support part 1c are interconnected and form a diffractive basic structure adapted to the different body areas of the patient lying thereon.
In the bed according to this example, the basic structure adapted to the whole body consists of the three above-mentioned interconnected support parts 1a . 1b and 1c , However, the base structure can also be divided into four parts or, as described, for example, in US Pat. Nos. 5,469,591, 5,448,789 and 5,388,290, many parts which form a diffractable base structure can be joined, provided that the basic structure to which they are attached The present invention relates to a back support member for lifting a patient lying thereon and a leg support member for raising the knees of a patient lying thereon.
In addition, the lifting device for lifting the back support member 1a and the leg support part 1b consist of the device described, for example, in the above-mentioned U.S. Patents 5,469,591, 5,448,789 and 5,388,290. In this case, a lifting arm with a roller at the top, which can be pivotally rotated by an electric drive device such as a motor, are installed so that the roller raises and supports each base member, or it may be at the bottom of each base part of a threaded shaft and an internally threaded screw engaging therein linearly movable member having a moving direction reversing mechanism attached thereto.
The lifting device for lifting the back support member 1a and the leg support part 1b can as explained below in an interlocking manner or so regulated that the individual carrier parts are actuated individually as needed.
In the above arrangement provides 1 a state in which the back carrier part 1a is raised to the highest position with the greatest inclination angle. In this state, the patient lying on it stands up, while the back is supported by the back support part 1a is supported.
For lowering all carrier parts 1a . 1b and 1c from this condition, so that they lie flat in a non-raised position, a control switch gives an operating command to a controller of the lifting device, causing the carrier parts to be lowered in an interlocking manner.
Upon receipt of this command, the controller will initially operate only on the lift device of the leg support member 1b to like in 2 shown only the leg support part 1b to raise.
Then the controller starts the back carrier part 1a at a time which is reasonably later than the time when lifting the leg support part 1b in response to the order. After that, as in 3 shown, the leg support part 1b further raised while the back carrier part 1a is put down.
According to the present invention, as described above, all the support members from a state in which the back support member 1a after pivoting rotation and raising at the highest angle of inclination, put down that they lie flat in a non-raised position, by first lifting the leg support part 1b and at a time that is reasonably later than the time when the lift was initiated, the back carrier portion 1a is put down. Therefore, at a time when the lowering of the back support member 1b begins to give the abdominal region of the lying patient a gliding force, the leg support part 1b already raised enough. As a result, the raised leg support part supports 1b the position of the abdominal region of the patient lying thereon and prevents the patient from slipping forward.
In this case, when the time at which the lowering of the backrest part 1a is later caused than at the time at which the lifting of Beinträ gerteils 1b is calculated in relation to the time that has elapsed since the time at which the lifting of the contributor part 1b has been initiated, the regulation of the adjustment process is simple.
The point in time at which to put down the backrest part 1a may be a time that is earlier than the time at which the leg support portion 1b reaches its highest position, or it may be the time at which the leg support portion 1b reached its highest position.
In the former method, wherein the leg support part 1b not reached its highest position at the time when the back carrier part 1a has the largest inclination angle, which is between the back support member 1a and the leg support part 1b formed angle greater than the angle in the second method, provided that the highest position of the leg support part 1b both methods are at the same level. Therefore, the situation is prevented in which the gradually narrowing angle causes the gradual compression of the abdominal region of the patient and thereby its discomfort.
If the above process continues to work as in 4 represented the leg support part 1b to reach its highest position stops the lifting of the leg support part 1b while putting down the backrest part 1a continues.
Then the controller begins, the leg support part 1b down from its highest position while lowering the backrest part 1a continues. It will therefore at this time both the back carrier part 1a as well as the leg support part 1b put down.
As in 6 shown, the back carrier part 1a down to its lowest limit position to lie flat in a non-raised position, and at this time the leg support portion remains 1b still in a slightly raised position. At a time that is reasonably later than the time in 7 shown time, reach all support parts 1a . 1b and 1c their lowest limit position and lie flat in a non-raised position.
As described above, the leg support part is 1b always raised sufficiently according to the present invention, while the back part 1a is pressed. As a result, it is possible to prevent the sloping back carrier part from being prevented 1a causing the patient lying on it to slide forward. It is therefore not necessary for the caregiver to return the patient to the starting position after all the support parts have been lowered and lie flat because the patient was not forced to slide forward on the bed.
The above-described control process according to the invention for the leg support part 1b and back carrier part 1a refers to a case where all Carrier parts have been put down from a condition and lie flat after the back carrier part 1a was pivoted and raised and had its greatest inclination angle. However, if the back support member is to be pivotally rotated and lifted from a state in which all the support members are down and flat in the non-raised position, then the operation described above is the exact opposite. Therefore, the lifting operation is not described here to avoid further unnecessary explanations. Even when lifting the back support member is prevented that the patient lying on the support parts slipping forward.
In a further embodiment of the present invention the different carrier parts also be raised without applying the process, the reverse to the shutdown process. For example, when lifting the Back support portion the leg support part be lowered to its lowest limit position before the back carrier part his highest Reached position.
8th Fig. 10 is a diagram exemplifying how the inclination angles of the back support member and the leg support member change when the method in which the lifting of the support members of the invention is performed by controlling the lift is applied.
in the Diagram shows the angle of inclination of the leg support part at any altitude chosen as ordinate, while the angle of inclination of the back support part at any altitude as abscissa.
In 8th the reference numerals a) to g) show the individual of the back support part 1a and leg support part 1b to be performed steps, when all the carrier parts from a state in which the back carrier part 1a having the greatest angle of inclination, having been pivoted and raised, lowered and lying flat in a non-raised position. The individual reference numerals correspond to the following steps.
Since the back carrier part 1a is not set down, its inclination angle remains at 78 degrees, and the angle of the leg support part is only increased to about 3 degrees.
Lowering the back carrier part 1a and lifting the leg support part 1b happens simultaneously. The angle of inclination of the back support part 1a is reduced from 78 degrees to 65 degrees, and at the same time the inclination angle of the leg support part 1b increased from 3 degrees to 15 degrees.
Lifting the leg support 1b is stopped, and only the back carrier part 2a is lowered further, reducing the inclination angle from 65 degrees to 55 degrees.
Lowering the back carrier part 1a and lifting the leg support part 1b happens again at the same time. The angle of inclination of the back support part 1a is reduced from 55 degrees to 40 degrees, and at the same time the inclination angle of the leg support part 1b increased from 15 degrees to 30 degrees.
Lifting the leg support 1b is stopped, and only the back carrier part 2a is lowered further, reducing the angle of inclination from 40 degrees to 15 degrees. The angle of inclination of the leg support part 1b stays 30 degrees.
In this step, the backing member is lowered 1a and lowering the leg support 1b at the same time, the angle of inclination of the back support part 1a from 15 degrees to the lowest limit of 0 degrees and also the angle of inclination of the leg support part 1b from 30 degrees to 15 degrees. As described, the leg support part remains 1b at a tilt angle of 15 degrees, although the angle of inclination of the back support member 1a reached its lowest limit of 0 degrees.
The leg support part 1b is lowered and its inclination angle is reduced from 15 degrees to the lower limit of 0 degrees.
As can be seen from the description of the above example, the lifting of the leg support part 1b be intermittent, although the lowering and lifting the backrest part 1a is continuous.
As described above, the present invention is a method for controlling the lifting of support members of a base structure for a bed or the like, comprising a back support member for lifting the patient thereon and a leg support member for raising the knees of the patient lying thereon, wherein the individual support members can be lifted with a respective lifting device, characterized in that in a case where all the support parts from a state in which the back support member remains inclined after being pivotally rotated and raised are placed down and lie flat, first lifting the leg wearer portion is caused, and that at a time which is reasonably later than the time when the lift was caused, the lowering of the back support member is caused; Thereafter, the lowering of the back support member is continued while the leg support member is raised to its predetermined highest position and then placed down ter until it is at a later time reaches lowest limit position and is flat than at the time when the back support member is placed down to its lowest limit position and flat in the non-raised position. There are therefore the following effects:
While the back support member is pivotally rotated and lowered, the leg support member remains in a raised position. As a result, the raised leg support part supports the position of the abdominal region of the patient lying thereon. Thus, although the back support member is lowered in this condition, the patient can be prevented from slipping forward.
If a patient lying thereon, e.g. a patient in an upright position Attitude, whose back from the back carrier part supported is in a normal supine position Therefore, it is not necessary that the Caregiver returns the patient to the original supine position, after all carrier parts have been put down and lie flat because the patient is not was caused to slip forward on the bed.
The Lifting the leg support part is not continued without regulation, but to a predetermined high location limited. This allows the between the back support part and the leg support part formed Angle does not become smaller than a predetermined angle. Therefore prevents the knee area of the lying patient in a higher position is raised as necessary, and that the resulting pressure causes discomfort on the abdominal region of the patient.
