Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical equipment, and in particular to an easy-to-walk frame for patients after arteriovenous fistula surgery. Background Art
[0002] Patients who need dialysis treatment need to undergo arteriovenous fistula surgery before dialysis. Arteriovenous fistula surgery is a surgical procedure to anastomose the patient's peripheral artery with the adjacent vein under the skin. After the operation, the vein gradually expands and arterializes. After puncture, sufficient blood flow can be obtained, becoming a permanent vascular access for hemodialysis for patients with chronic renal failure. Within 72 hours after arteriovenous fistula surgery, the lymphatic return is blocked due to increased venous pressure, and the arm will swell to varying degrees. Therefore, the patient's limb on the side of the fistula should be raised to 30° above the horizontal to ensure smooth blood flow, because raising the limb can promote blood return. Prevent venous congestion, reduce venous pressure and reduce edema, and keep the limb on the side of the surgery in a comfortable functional position without affecting activities. The traditional method is to use soft items such as pillows, quilts or clothes to raise the arm, but this method can only be used when the patient is lying down. However, when the patient is active, it is difficult to keep the arm on the side of the surgery high, so a device that can help the patient lift the arm and facilitate the patient's movement and activity is needed to facilitate the patient's life during the postoperative recovery period. Summary of the invention
[0003] The purpose of the present invention is to provide a patient-friendly stent after arteriovenous fistula surgery to solve the problems raised in the above-mentioned background technology.

The oblique support 5, the arm guard support 4 and the support connector 2 together form a triangular support structure, which can stably support the arm held up on the arm guard support 4 to keep the arm above the heart line.
[0028] Embodiment 2
[0029] As attached Figure 2-4 As shown, based on the first embodiment, the torso support 1 is wrapped around the waist and abdomen of the user in the form of a waist strap, and the end of the waist strap is connected and fixed with Velcro 11. The connection and contact are simple and quick, and it is easy to use. The waist strap and Velcro connection are both existing technologies.
[0030] The support connecting member 2 includes a telescopic sleeve 21 and a telescopic sleeve rod 22. The telescopic sleeve 21 is fixedly connected to the outer side surface of the trunk support member 1. The telescopic sleeve 21 is a hollow tubular structure. A telescopic sleeve rod 22 is slidably connected in the telescopic sleeve. A rotating sleeve 23 is rotatably connected to the top of the telescopic sleeve rod 22. An inverted truncated cone-shaped rotating head is provided at the upper end of the telescopic sleeve rod 22. The rotating sleeve 23 is provided with a connecting chamber corresponding to the rotating head from the lower end, so that the rotating sleeve 23 can be sleeved on the rotating head at the upper end of the telescopic sleeve rod 22 for rotation. A joint member 3 is fixedly connected to the top of the rotating sleeve 23. The two ends of the joint member 3 are respectively connected to the rotating sleeve 23 and the arm guard support member 4. The joint member 3 itself can be rotatably adjusted, and the adjustment direction is in the vertical direction. The arm guard support member 4 that supports the arm can be rotatably adjusted relative to the support connecting member 2 in the vertical direction, so that the angle between the arm and the body can be adjusted so that the arm can maintain the most comfortable angle for support.
[0031] The joint component 3 can be replaced with a component with the same function but different structure with the help of existing relevant technology. The joint component 3 in this embodiment includes a support arm 31 and a clamping arm 32. The support arm 31 and the clamping arm 32 are rotatably connected through a rotating shaft 33. The rotating shaft 33 is arranged in the horizontal direction. The support arm 31 is fixedly connected to the rotating sleeve 23, and the clamping arm 32 is fixedly connected to the arm guard support 4, so that the arm guard support 4 can rotate relative to the supporting connecting member 2 where the rotating sleeve 23 is located, so as to realize the rotation of the arm guard support 4 relative to the supporting connecting member 2 in the vertical direction, and adjust the angle between the patient's upper arm and torso, so as to facilitate the patient to obtain a comfortable posture and reduce the patient's discomfort.
[0032] The side of the joint part 3 away from the supporting connecting part 2 is fixedly connected to the arm guard support part 4, and the arm guard support part 4 includes a support rod 41, and the top surface of the support rod 41 is fixedly connected to the arm guard plate 42. The arm guard plate 42 is an arc-shaped plate, and its arc-shaped opening end is opened upward to support the patient's upper arm. The arc-shaped structure can well support the patient's arm and increase the supporting area.
[0033] Preferably, an anti-slip plate is rotatably connected to the upper end of the arm guard plate 42. The anti-slip plate can be rotatably buckled on the arm guard plate 42 to form a tubular structure together with the arm guard plate 42, which can limit the arm inside and play a certain restraining role.
[0034] An oblique support member 5 is provided at the lower end of the arm guard support member 4, one end of the oblique support member 5 is fixedly connected to the arm guard support member 4 or one of the supporting connectors 2, and the other end of the oblique support member 5 is slidably connected to the other one. In this embodiment, the oblique support member 5 includes an oblique rod 51, a first rotating seat 52 and a second rotating seat 53, the two ends of the oblique rod 51 are rotatably connected to the first rotating seat 52 and the second rotating seat 53 respectively, the first rotating seat 52 is fixedly connected to the bottom end surface of the arm guard support member 4, the second rotating seat 53 is slidably connected to the telescopic sleeve 21, and the second rotating seat 53 includes an arcuate slide 55 and a rectangular slide 56. A vertical slideway is provided on the telescopic sleeve 21, and the telescopic sleeve 21 is slidably connected to the rectangular slide 56 through the slideway. The rectangular slide 56 can slide up and down along the slideway, and a first positioning hole is provided on the rectangular slide 56, and a first positioning hole is provided in the first positioning hole. The first positioning hole of the positioning bolt 57 completely penetrates the rectangular slide 56. The first positioning bolt 57 is threadedly connected in the first positioning hole. Screwing in the first positioning bolt 57 can make the first positioning bolt 57 screwed in and press its end against the surface of the telescopic sleeve rod 22, so that the rectangular slide 56 and the telescopic sleeve rod 22 can be kept fixed. The rectangular slide 56 includes a slider and an arcuate slide 55. The arcuate slide 55 is an arc-shaped structure. A slide groove is provided on the outer surface of the arcuate slide 55 in the horizontal direction. The arcuate slide 55 includes a second slider and a rectangular slide 56. The second slider is fixedly connected to the rectangular slide 56. The rectangular slide 56 is slidably connected to the slide by the second slider. The rectangular slide 56 in the groove can slide along the slide groove, and its sliding track is a track for rotating around the telescopic sleeve 22. Using the same principle, a second positioning bolt 58 is provided on the rectangular slide 56 so that the rectangular slide 56 can be fixed to the arcuate slide 55. When adjusting the device, when the rotating sleeve 23 is rotated, the entire arm support 4 needs to rotate with it, so the inclined support 5 can follow the rotation of the rotating sleeve 23 through the rectangular slide 56. The second positioning bolt 58 on the rectangular slide 56 can fix the rectangular slide 56 to the arcuate slide 55, and the fixation of the rectangular slide 56 will also be fed back to the rotating sleeve 23, so that the rotation The sleeve 23 also remains fixed and cannot rotate. The telescopic sleeve 21, the guard arm support 4 and the oblique support 5 together form a triangular structure. When the telescopic sleeve 21 is telescopically adjusted, since the length of one side of the triangle changes, the length of the other side needs to be changed at the same time to keep the triangle shape. Therefore, the arc-shaped slide seat 55 is designed to be slidably connected to the telescopic sleeve 21 to cooperate with the telescopic adjustment of the telescopic sleeve 21. At the same time, with the telescopic adjustment of the telescopic sleeve 21, the angle between the entire guard arm support 4 and the horizontal plane will also change. Therefore, the connection point between the oblique support stem and the support connector 2 changes accordingly to enable the guard arm support 4 to maintain its original state and angle.

One end of the connecting rod 61 is rotatably connected to the support rod 41 through a rotating shaft, and the lifting plate 62 is fixedly connected to the connecting rod 61. The entire forearm lifting piece 6 is used to lift the forearm to prevent the forearm from being suspended in the air for a long time and causing discomfort. At the same time, the forearm lifting piece 6 can rotate in a relatively horizontal direction to prevent the forearm from sagging to a position below the cardiac border and affecting the closure of the fistula. The lifting plate is also an arc-shaped plate adapted to the arm so as to provide better support.
