Description

Technical Field

[0001] This utility model relates to the field of nursing auxiliary equipment technology, specifically to an upper limb support for the treatment of lymphedema. Background Technology

[0002] Lymphedema refers to the obstruction of lymphatic fluid return in subcutaneous tissues, causing lymphatic fluid to accumulate in the interstitial spaces, widening the interstitial spaces, leading to lipid deposition and abnormal proliferation such as subcutaneous fibrous connective tissue. This results in thickened and rough skin, commonly seen on the lower legs and upper arms.

[0003] Currently, most treatments for lymphedema are non-surgical, involving postural drainage combined with compression bandaging. During treatment, medical staff guide the patient to elevate the affected limb to approximately horizontal position, then wrap elastic stockings and bandages from the distal end to the proximal end of the limb. Because compression therapy takes a relatively long time, it is generally difficult for patients to maintain their upper limb elevated for an extended period, which can cause discomfort and affect the quality and efficiency of the treatment.

[0004] Therefore, an upper limb brace for the treatment of lymphedema was proposed. Utility Model Content

[0005] The purpose of this invention is to provide an upper limb support for the treatment of lymphedema that is simple to move, easy to use, and does not easily interfere with the operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This utility model provides an upper limb support for the treatment of lymphedema, including a base and a telescopic rod vertically connected to the base. The upper end of the telescopic rod is provided with a U-shaped connector, and a U-groove ear plate is rotatably connected to the U-shaped connector. The U-groove ear plate is provided with a insertion hole, and a positioning component for limiting the tilt angle of the U-groove ear plate is connected to the insertion hole. A crossbar is connected to the upper end of the crossbar, and arm supports are connected to both ends of the crossbar. A clearance hole is provided in the middle, and a control component is connected inside the clearance hole. The upper part of the control component extends out of the clearance hole, and the lower part extends into the groove of the U-groove ear plate.

[0037] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0038] This utility model provides an embodiment 60 of an upper limb support for the treatment of lymphedema. See also... Figure 1 , Figure 2 , Figure 3 The device includes a base 1 and a telescopic rod 30 vertically connected to the base 1 by threads. The side of the telescopic rod 30 is connected to a hand-tightening screw 3 for adjusting and limiting the length of the telescopic rod 30 (this is prior art, and the usage method is the same as existing products, so it will not be described again). The upper end of the telescopic rod 30 is provided with a U-shaped connector 31. A U-groove ear plate 2 is rotatably connected to the U-shaped connector 31 via a shaft 4. The U-groove ear plate 2 is provided with a insertion hole, and a positioning element 9 is connected to the insertion hole. A crossbar 6 is connected to the upper end of the U-groove ear plate 2. Arm supports 10 are inserted into both ends of the crossbar 6. A positioning screw 5 for limiting the extension degree of the arm supports 10 is connected to the lower end of each end of the crossbar 6. A clearance hole 7 is provided in the middle. A control element 20 is connected in the clearance hole 7. The upper part of the control element 20 extends out of the clearance hole 7, and the lower part extends into the groove of the U-groove ear plate 2.

[0039] The specific implementation method is described below:

[0040] The positioning component 9 includes two locking tongues 40, a spring 8, and a piston 50. Each locking tongue 40 includes a rod body 41, with a rounded end 411 at one end and a blind hole 413 at the other. A raised ring 412 is provided on the outer peripheral wall away from the rounded end 411. The rod body 41 is movably inserted into the insertion hole on the U-groove ear plate 2. A limiting ring 52 is provided in the middle of the outer peripheral wall of the piston 50, and the piston 50 is movably inserted into the blind hole 413. The spring 8 is located within the blind hole 413 and contacts the end face of the piston 50. (See attached image.) Figure 2 , Figure 3 , Figure 4 , Figure 5 .

[0041] The upper end of the U-shaped connector 31 has an equilateral triangular structure, and the end face 311 of the U-shaped connector 31 is a sloping surface with a higher outer side and a lower inner side. (See attached image.) Figure 2 , Figure 3 .

[0042] The control component 20 includes a rocker arm 22 and a handle 21 rotatably connected within the clearance hole 7. The handle 21 is connected to the upper end of the rocker arm 22, and a magnet 221 is connected to the lower end of the rocker arm 22. The lower end of the rocker arm 22 extends into the groove of the U-shaped ear plate 2 and can contact the outer peripheral surface of the latch 40 near the blind hole 413. (See [reference]) Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 .

[0043] The arm support 10 includes a support rod 11 and a support member 12. The support member 12 includes a bracket 122 fixedly connected to one end of the support rod 11. A soft pad 121 is connected inside the bracket 122. The other end of the support rod 11 is inserted into the end of the crossbar 6. The extension degree of the arm support 10 can be adjusted by loosening the positioning screw 5 and pushing or pulling the support rod 11. After adjustment, the positioning screw 5 can be tightened for positioning. See [link to relevant documentation] Figure 1 , Figure 6 .

[0044] In this embodiment, the rocker arm 22 and the locking tongue 40 are both made of carbon steel; the U-slot ear plate 2 and the crossbar 6 are both made of aluminum alloy or copper; the support rod 11 and the crossbar 6 are both made of rigid square tubing such as aluminum alloy; in order to reduce frictional resistance, reduce wear, and achieve field adjustment, lubricating material is applied to the rotating (e.g., the position of shaft 4) and sliding contact parts (e.g., the lower end of rocker arm 22, the round end 411).

[0045] This utility model relates to the method of using a bandage for pressure treatment of lymphedema:

[0046] S1. Placement and adjustment: The patient sits on a stool or bed and places the present invention near the middle and outer side of the patient's forearm (with the upper limb raised). Tighten the hand screw 3 to adjust the height of the telescopic rod 30 so that the height of the handle 2 is approximately between the patient's nipple and armpit. Tighten the positioning screw 5 to adjust the length of the arm support 10 extending from the crossbar 6 so that the soft pads 121 on the front and rear supports 12 can support the forearm and distal upper wall of the affected limb respectively (adjustment can be omitted if the present invention is suitable).

[0047] S2. Medical personnel stand in front of this utility model, pull handle 21 back to its end, and raise the rear support 12 to support it under the distal end of the affected limb's upper arm. (See attached diagram) Figure 9 (If it is already in this state, there is no need to pull handle 21 to adjust it);

[0048] S3. After wrapping the bandage from the distal end of the affected limb to the proximal end up to the elbow, support the affected limb with one hand and push the handle 21 forward with the other hand to the end (the front support 12 rises and the rear support 12 falls). Then place the distal end of the forearm of the affected limb on the soft pad 121 of the front support 12 and continue to wrap the bandage from the proximal end until it is finished.

[0049] In addition, the above-described method of use can be used as an upper limb support for massage therapy of lymphedema.

[0050] The principle of the control component 20 provided by this utility model for switching and locking the tilt direction of the crossbar 6 is as follows:

[0051] When switching the tilt angle of the crossbar 6, one hand supports the patient's arm, and the other hand pushes or pulls the handle 21 in the direction of the pre-tilt (i.e., forward or backward). During this process, the lower end of the swing arm 22 (opposite to the direction of movement of the handle 21) disengages from the latch 40 on the already attracted side. (After disengagement, the lower end of the swing arm 22 no longer extends into the protruding rings 412 of the two latches 40 on that side. Under the pressure of the pre-descending end and the pushing or pulling action of the handle 21, the round end 411 of the latch 40 on that side can retract into the U-groove ear plate 2 like the latch of a normal door lock.) Inside the hole, the latch 40 on this side no longer restricts the U-shaped lug 2 from rotating to the other side, swings to the latch 40 on the opposite side and adheres to its outer peripheral wall away from the round end 411. When the U-shaped lug 2 rotates until the latch 40 with the rocker arm 22 adhering to it is no longer blocked by the U-shaped connector 31, the round end 411 of the latch 40 on this side extends out of the insertion hole. At the same time, the lower end of the rocker arm 22 further extends into the convex ring 412 between the two latches 40 on this side, thereby preventing the latch 40 on this side from retracting into the insertion hole, realizing tilt angle switching and tilt angle locking. See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 .

[0052] The above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
