Description

Technical Field

[0001] The invention relates to the technical field of internal fistula maturation training, and in particular to a training device for promoting internal fistula maturation. Background Art

[0002] Fistula refers to a tubular channel formed between two internal organs or between an internal organ and the body surface due to some reason. When kidney patients receive hemodialysis, vascular access needs to be established. Autologous arteriovenous fistula is our preferred access. To ensure effective dialysis, the fistula needs to have sufficient blood flow. Regular strengthening exercises can be performed 2 weeks after fistula formation surgery to help expand the fistula blood vessels, promote the maturation of the arteriovenous fistula, and ensure sufficient blood flow.

[0003] At present, the existing fistula maturation training equipment has the following shortcomings in use: first, the professional fistula-promoting equipment is large in size and is not suitable for fistula maturation training for most patients before and after surgery. Such patients need to breathe fresh air and take a walk outdoors frequently. Then, when they need to perform training outside, they cannot use training equipment and can only use grip balls and grip rings. Although this training method has a certain effect, it is very subjective and arbitrary depending on the patient, and it is also necessary to use external auxiliary tools, such as folded towels, wrist pads, etc. for training. Even after repeated training, it is difficult to achieve the final effect of filling, thickening and enlarging the fistula blood vessels, thereby reducing the efficiency and quality of fistula maturation. In addition, when cooperating with fistula-promoting exercises, it requires a lot of arm strength from the patient, which is easy to affect the physical state of patients with poor mental state, leading to accidents and affecting the overall use effect and safety. Summary of the invention

[0004] In view of the above-mentioned problems existing in the existing fistula-promoting exercise equipment, the present invention is proposed.

The movement can also drive the traction rod in the second placement tube to move, thereby pulling the first stretching muscle back and forth. When the first stretching muscle moves, it drives the rack rod to move, thereby driving the gear to rotate clockwise, so as to drive the coaxial linkage wheel to rotate an angle, and push the push rod to rise, further driving the two pressure clamps to move closer to each other. During the contraction movement of the palm and fingers, the arm can be clamped synchronously to ensure the blood flow rate of the blood vessels, promote blood circulation, increase the maturation effect of the internal fistula, and improve the quality of subsequent treatment. By rotating the patient's arm, the control plate can be driven to rotate, thereby driving the placement pad, the lower arm frame and the linkage wrist frame to rotate. When the upper arm frame rotates, the rotating seat follows the rotation. When the patient is doing horizontal lifting exercises, the rotating seat drives the transfer frame to move, further driving the first support rod and the second support rod to move. During the rising process, the first support rod drives one of the positioning blocks to slide upward in the positioning rod, the first spring gradually resets, and the second support rod drives the other positioning block to rise as well, thereby providing an upward force for promoting the instrument and reducing the lifting force of the patient.

[0044] The reciprocating sliding of the traction rod 202d can also drive the limiting slider 205e to slide in the slideway 205d, thereby driving the stretching rod 205f to move, and pulling the heating leather strip 205b back and forth. When pulling, the drilling heating seat 205a is driven to rotate and generate heat by friction. The other end slides on the auxiliary heating rod 205c to increase the friction heat effect of the heating leather strip 205b, and then the heat is transferred to the heat-conducting wire mesh 205g through the drilling heating seat 205a, thereby heating the entire airbag 202a, promoting blood circulation, and passing through the T-shaped rod 202e.

When the patient rotates his arm, it can drive the control plate 105 to rotate, thereby driving the placement pad 106a, the lower arm frame 108 and the linkage wrist frame 107 to rotate. When the upper arm frame 106 rotates, the rotating seat 206a follows the rotation. When the patient is doing horizontal lifting exercises, the rotating seat 206a drives the middle rotating frame 206b to move, and further drives the first support rod 206c and the second support rod 206d to move. During the rising process, the first support rod 206c drives one of the positioning blocks 206f to slide upward in the positioning rod 206e, and the first spring 206g is gradually reset, and the second support rod 206d drives the other positioning block 206f to also rise, thereby providing an upward force for promoting the device and reducing the lifting force of the patient.

[0047] Example 3

[0048] Reference Figures 1 to 8 , which is the third embodiment of the present invention, and this embodiment is the specific working principle of the present invention, comprising the following steps:

[0049] When the patient uses this device, he puts the arm to be established with internal fistula through the arm sleeve 102, absorbs the hanging arm 103 to fit and stick to the shoulder, then buckles the waist belt 104 around the waist, pulls out the elastic band to fix it, places the arm on the placement pad 106a, inserts the fingers into the docking finger sleeve 201c, and drives the linkage wrist frame 107 to move through the movement of each finger, so that the pulling finger 201b moves, thereby pulling the second stretching muscle 201d. When the second stretching muscle 201d is pulled, it can drive the traction rod 202d to slide in the first placement tube 202c, and pull the T-shaped rod 202e to slide in the sleeve 202b during sliding, and compress the second spring 202f. At this time, the gas in the sleeve 202b is discharged from the inflation tube 202g to the airbag 20 2a, when the second spring 202f is reset, the air inlet pipe 202j inhales air, and after multiple grasping, the airbag 202a begins to fill, thereby cushioning the patient's wrist without the need for assistance such as folding a towel. When it is sufficiently filled, the pressure relief valve 202h automatically releases excess gas to maintain the filled state. At the same time, in this process, the reciprocating sliding of the traction rod 202d can also drive the limiting slider 205e to slide in the slide 205d, thereby driving the stretching rod 205f to move, and the heating leather strip 205b is pulled back and forth. When pulled, the drilled heating seat 205a is driven to rotate and generate heat by friction. The other end slides on the auxiliary heating rod 205c to increase the friction heat effect of the heating leather strip 205b, and then the heat is transferred to the heat conductor through the drilled heating seat 205a. The wire mesh 205g is moved on the wire mesh 205a, thereby heating up the entire airbag 202a to promote blood circulation. The sliding of the T-shaped rod 202e can also drive the traction rod 202d in the second placement tube 204c to move, thereby reciprocatingly pulling the first tie rod 204b. When the first tie rod 204b is active, it drives the rack rod 106d to move, thereby driving the gear 203b to rotate clockwise, so that the coaxial linkage wheel 203a is driven to rotate an angle, and the push rod 203c is pushed up, and the two pressure clamps 203d are further driven to move closer. During the contraction movement of the palm and fingers, the arm can be clamped synchronously to ensure the filling state of the blood vessels. When the rack rod 106d moves, it drives the linkage rod 106c to slide in the groove 106b, pushing the elastic head 10 6e squeezes the spring member to reset it. When the patient rotates his arm, it can drive the control plate 105 to rotate, thereby driving the placement pad 106a, the lower arm frame 108 and the linked wrist frame 107 to rotate. When the upper arm frame 106 rotates, the rotating seat 206a rotates accordingly. When the patient is doing horizontal lifting exercises, the rotating seat 206a drives the middle rotating frame 206b to move, and further drives the first support rod 206c and the second support rod 206d to move. During the rising process, the first support rod 206c drives one of the positioning blocks 206f to slide upward in the positioning rod 206e, and the first spring 206g gradually resets, and the second support rod 206d drives the other positioning block 206f to rise as well, thereby providing an upward force to promote the device and reducing the lifting force of the patient.
