Intravenous needles and cannulas, also referred to as venous access devices, must he secured to patients to prevent dislodgment during medical treatment. The term needle will be used herein to refer to both needles and cannulas. The location of the needle insertion point or points on a patient vary with the type of medical treatment and the location of a suitable vein. Such locations include for example an upper arm, a surface on the outside surface of a hand, a wrist of a hand, a lower arm or an inside of an elbow of an arm. In dialysis treatment, a special site is typically created to provide for a strengthened vein, most commonly in the forearm and less frequently in the leg, to repeatedly accept two large needles and provide for sufficient flow of blood. The special site is created by joining a vein and an artery and is called a fistula and receives two arterial-venous (AV) fistula needles. In any of the above mentioned locations, it is very difficult to keep the needle secured to operate satisfactorily. In dialysis treatment, where the treatment is prolonged, repeated frequently, and two large needles are used, the problem of securing the needles is exasperated.
The invention at hand solves the above noted problems. In the securement of the needles or a needle in either a dialysis or other intravenous (IV) procedure, no adhesives arc used. Once a needle is placed within a vein, the needle is kept in place by straps that cross each other in that particular location. The straps are derived from and are fixed to a pad that is placed on an opposite side of the limb, hand or other part of the patient's body to which the needle is located. As the straps are moved around the location of the needle, they will cross that location and will return to their origin of the other side of the pad and will be fastened thereto. More than one strap will cross each other at the needle to thereby securely hold the needle in place at that location. A first strap can be used to apply a first pressure to secure the needle. A second strap can be used to apply a second pressure to further secure the needle.
FIGS. 1 and 2 illustrate how the present invention is applied to an inner surface of an upper arm of a patient to secure two intravenous (IV) needles 5 and 6, such as two arterial-venous (AV) fistula needles. Needles 5 and 6 respectively have tubes 9 and 10 and tabs, also called wings, 7 and 8 attached thereto to form needle assemblies also referred to herein as needle assemblies 9 and 10, respectively. The embodiment depicted in FIGS. 1 and 2 employs four straps 1, 2, 3 and 4 to hold the two needles in place. In the orientation shown in FIGS. 1 and 2, straps 1 and 2 are upper straps and straps 3 and 4 are lower straps. Strap 1 is fastened to an oval pad 11 by way of a grommet 1 a. Grommet 1 a should be fastened in such a way so that the strap 1 can rotate relative to the pad 11 and can follow the angle of direction to which the strap 1 is forced when it is applied thereby preventing kinks. This is also true for grommets 2 a, 3 a and 4 a which fasten straps 2, 3 and 4 to the pad 11 respectively. The pad 11 is applied to the outer arm if the locations if the needles 5 and 6 are applied to the inner arm. In this application, the upper straps 1 and 2 cross each other over the upper needle 5 and return to the pad 11 where both of the straps are fastened to the pad 11 by way of the well known hook and loop fastening system, VELCRO™. This is equally true for the lower straps 3 and 4 which cross each other over the lower needle 6. This way the upper straps 1 and 2 and the lower straps 3 and 4 can each be individually adjusted to properly fit over the tab 7 of upper needle assembly 9 and tab 8 of lower needle assembly 10, respectively. The needles 5 and 6 are held in place by crossing straps 1 and 2, and 3 and 4, over tabs 7 and 8, respectively. The needles are thereby securely fastened without adhesive bandages, the injection points and treatment sites are easily observed, and the patient has some ability for movement.
FIG. 3 shows the pad 11 of FIGS. 1 and 2 when it is not applied to a patient. The pad 11 has hooks 11 a of the VELCRO™ system on an outer surface as indicated in FIG. 3. The four straps 1, 2, 3 and 4 are fastened to the pad 11 at 1 a, 2 a, 3 a, and 4 a by grommets that are applied in such a manner so that the straps are able to rotate into the direction by which they are forced by the application of the pad and the location of the needles themselves. Straps 1, 2, 3 and 4 have loops of the VELCRO™ system applied to the surface facing pad 11 (not shown), which also faces the patient when the device is applied. The loops of the VELCRO™ system tend to be softer and more compliant than the hooks. Thus patient comfort can be improved with this arrangement of the hooks and loops. Furthermore, the more compliant loops will better conform to the tabs 7 and 8 thereby providing for good retention thereof. Alternatively, the outer surface of the pad 11 could have the loops thereon so that the VELCRO™ system cannot snag on any outer garment. However, this arrangement would require the hooks to be applied to straps 1, 2, 3 and 4 and the previously mentioned patient comfort and tab retention may be lessened as, a result.
FIG. 4 illustrates a pad 12 having three corners in a triangular shape where straps 13, 14 and 15 are applied. Again, the straps 13, 14 and 15 are fastened by way of grommets 13 a, 14 a and 15 a, respectively, in a rotational manner as was explained with regard to FIG. 3, and have VELCRO™ loops on the surface facing pad 12 as exemplified by section 16 of strap 15. Again, the outer surface of the pad comprises hooks 12 a of VELCRO™ as explained above. The pad 12 of FIG. 4 is used in the event when a needle is applied to the back of a hand as shown in FIGS. 5 and 6. The three straps 13, 14 and 15 are applied as shown in FIG. 5 where the straps 13 and 14 cross each other over a tab 17 and the strap 15 secures the implement around the wrist of the patient. FIG. 6 shows the implement of FIG. 5 as it is applied to the inside of the hand. The triangular shape of the pad 12 can clearly be seen in FIGS. 4 and 6.
FIG. 7 shows a different pad 20 of a substantially rectangular configuration having straps 25, 26, 27 and 28 fastened by way of grommets 25 a, 26 a, 27 a and 28 a, respectively, in a rotational manner as discussed in pads 11 and 12, and have VELCRO™ loops on the surface facing pad 20 as exemplified by section 29 of strap 27. The outer surface of the pad 20 comprises hooks 20 a of VELCRO™ as explained above. One end of pad 20 is somewhat enlarged where the grommets 25 a and 26 a are located. This pad can be used when a needle is inserted on the inside wrist of a hand as can be seen in FIGS. 8, 9 and 9 a. Referring first to FIGS. 8 and 9, the pad 20 is placed on the outside of the hand and the straps 27 and 28 cross each other over a tab 21 of a needle assembly 22. Straps 25 and 26 serve to additionally secure the pad 20 and the tube of needle assembly 22 to the hand. Referring now to FIG. 9 a, this system will work perfectly well even if the IV is somewhat offset from the middle of the wrist. The straps 26 and 28 cross over a tab 33 on an IV assembly 31. This is a somewhat complicated installation, but the cooperation between the pad 20 and the straps 25, 26, 27 and 28 makes for a versatile installation.
FIG. 10 shows a yet a different pad 35 which can be installed at the elbow of a patient. This pad comes is particularly useful when a needle is to be inserted at the inside of the inner arm opposite an elbow. Pad 35 has straps 37, 38, 39 and 40 fastened by way of grommets 37 a, 38 a, 39 a and 40 a, respectively, in a rotational manner as discussed in pads 11, 12 and 20, and have VELCRO™ loops on the surface facing pad 35 as exemplified by section 45 of strap 37. The pad 35 is made up of two parts 41 and 42 having outer surfaces comprising hooks 41 a and 42 a, respectively, of VELCRO™ as explained above. The parts 41 and 42 are connected by way of the grommets 43 and 39 a. Grommet 39 a is therefore fastening together strap 39 and parts 41 and 42. The two parts 41 and 42 have opposing curved inner edges and when connected together leave an open space 44 which will fit around the elbow. The grommets 43 and 39 a enable the parts 41 and 42 to rotate around each other so that once the pad is installed on the elbow, the two parts 41 and 42 will be able to move with the movement of the elbow. FIG. 11 shows the installation of the pad 35. FIGS. 11 and 12 show how the pad 35 and an IV assembly 47 having a tab 46 are held in place. To this end, the strap 40 circles the arm below the elbow while holding a loop of tube of assembly 47 in place. The straps 37 and 38 cross each other over the tab 46 while the strap 39 circles around the arm just above the elbow. This arrangement assures for a secure holding of the IV needle in place while at the same time affording visibility of the performance of the needle itself while the arm may rotate around the elbow.
The pad itself, in all of the above described installations, should be made of a semi-rigid material. That is, it should not give in any planar direction; yet, it should be bondable so that it can conform to any contours of an arm, hand, leg or other part of the body. The pad should not turn or flex with the different directions the straps may take. The grommets should allow the straps to turn relative to the pad. The application of two straps crossing over the needle assembly and tab thereof as described in the above installations, enables a first strap to apply a first pressure to initially secure and position said assembly, and a second strap to apply a second pressure further securing said assembly. As noted above, the pad can comprise hooks of the VELCRO™ fastening system, thereby allow the softer loops thereof to be used on the straps which face the patient. Patient comfort can be improved with this arrangement of the hooks and loops. Furthermore, the more compliant loops will better conform to the tabs of needle assemblies thereby providing for good retention thereof. Alternatively, the outer surface of the pad 11 could have the loops thereon so that the VELCRO™ system cannot snag on any outer garment. However, this arrangement would require the hooks to be applied to the straps and the previously mentioned patient comfort and tab retention may be lessened as a result. In an alternative embodiment, adhesives could be used to attach the straps to the pads after wrapping said straps around the patient. In this embodiment, the adhesive could be applied such that it would not come into contact with the patient. This embodiment may be preferable when the device is to be disposed of after a single use. However, the VELCRO™ system may provide a more secure attachment of the straps to the pad than an adhesive. Furthermore, as noted above, the soft and compliant loops of the VELCRO™ system may provide for improved patient comfort and improved retention of the tabs of the needle assemblies.
