Description

Technical Field

[0001] This utility model belongs to the field of rehabilitation exercise technology, and in particular relates to a pressure-adjustable grip ball. Background Technology

[0002] Arteriovenous fistulas are known as the lifeline of dialysis patients. Autogenous arteriovenous fistula formation is a surgical procedure that anastomoses the superficial adjacent arteries and veins of the patient, allowing arterial blood to flow into the superficial veins, which is conducive to achieving the required blood flow for dialysis and facilitating the establishment of extracorporeal circulation through vascular puncture. Grip strength is an important indicator for evaluating forearm and hand function or clinical outcome.

[0003] Existing devices have limitations in use, such as the inability to freely adjust the amount of air inside the grip ball to control the required pressure and adjust the intensity of grip training. They are also insufficient to meet the needs of users who require different intensities of rehabilitation training as the treatment progresses, resulting in relatively low versatility of the devices. Therefore, we propose a pressure-adjustable grip ball. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-adjustable grip ball. By using a vent plate, it solves the problem that it is not easy to freely change the amount of air inside the grip ball to control the required pressure level in order to adjust the intensity of grip training. This is also insufficient to meet the needs of users who need to carry out different intensities of rehabilitation training as the treatment progresses, resulting in relatively low versatility of the device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a pressure-adjustable grip ball, including a grip ball, a pressure gauge fixedly connected to the top outer wall of the grip ball, an air nozzle fixedly connected to the top outer wall of the pressure gauge, and an adjustment mechanism provided on the outer wall of the end of the grip ball away from the pressure gauge.

[0007] The adjustment mechanism includes an adjustment tube, a vent plate is fixedly connected to the outer wall of the adjustment tube, a piston groove is formed on the inner wall of the adjustment tube, a connecting rod is slidably connected to the inner wall of the vent plate, a button is fixedly connected to the outer wall of the connecting rod, a piston is fixedly connected to the outer wall of the end of the connecting rod away from the button, and the outer wall of the piston is slidably connected to the inner wall of the piston groove.

[0008] Furthermore, the bottom outer wall of the adjustment tube is provided with a wearing mechanism, the wearing mechanism includes a connecting seat, the inner wall of the connecting seat is provided with an installation groove, and an installation block is slidably connected to the inner wall of the installation groove.

[0009] Furthermore, the inner wall of the mounting block is provided with a fixing groove, and the outer wall of the connecting seat is fixedly connected with a pin seat, the inner wall of the pin seat being provided with a pin groove.

[0010] Furthermore, a pin is slidably connected to the inner wall of the pin groove, the outer wall of the pin is slidably connected to the inner wall of the fixing groove, and a push button is fixedly connected to the outer wall of the pin.

[0011] Furthermore, a spring is fixedly connected to the bottom outer wall of the pin, and the outer wall of the end of the spring away from the pin is fixedly connected to the inner wall of the pin groove.

[0012] Furthermore, a connecting rope is rotatably connected to the bottom outer wall of the mounting block, and a fixed seat is rotatably connected to the outer wall of the end of the connecting rope away from the mounting block.

[0013] Furthermore, a connecting belt is fixedly connected to the outer wall of the fixed base, and a plurality of adjustment grooves are provided on the inner wall of the connecting belt. The connecting belt is also fixedly connected to the outer wall of the fixed base.

[0014] Furthermore, a gathering frame is slidably connected to the outer wall of the second connecting band, a connecting shaft is rotatably connected to the inner wall of the end of the second connecting band away from the fixed seat, a fixed frame is rotatably connected to the outer wall of the connecting shaft, and a fixing tooth is fixedly connected to the outer wall of the connecting shaft.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a vent plate, and a pressure gauge measures and displays the required pressure inside the grip ball. The higher the required pressure inside the grip ball, the greater the force needed to squeeze it. To adjust the required pressure, simply press the button inward. The button moves the connecting rod, which in turn moves the piston. This allows for free adjustment of the amount of air inside the grip ball to control the required pressure and thus adjust the intensity of grip training. This meets the needs of users who require different intensities of rehabilitation training as the treatment progresses, indirectly enhancing the versatility of the device.

[0017] 2. This utility model, by setting a connecting strap, allows users to directly pass their hands through the connecting strap and the second connecting strap to complete the wearing of the device. If the size of the device needs to be adjusted, simply pinch the second connecting strap and the connecting strap inward. The second connecting strap will cause the fixing teeth to rotate and fall out of the adjustment groove. Then, adjust the fixing teeth to other adjustment grooves and pass them through to lock them into the fixing frame. If the connecting rope needs to be removed, simply press down on the push button. After the push button falls out of the fixing groove and is no longer stuck in the mounting groove, rotate the mounting block counterclockwise and pull it out of the mounting groove. This achieves the effect of freely adjusting the wearing size of the device and preventing the grip ball from falling out of the user's hands during grip strength training, thus preventing the user from spending extra time picking it up.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] One specific application of this embodiment is:

[0034] When staff need to use the device, they can directly inject air into the grip ball 1 through the air nozzle 102. The pressure gauge 101 will measure and display the required pressure inside the grip ball 1. The higher the required pressure inside the grip ball 1, the greater the force required to squeeze the grip ball 1. If it is necessary to adjust the required pressure inside the grip ball 1, simply press the button 205 inward. The button 205 drives the connecting rod 204 to move, and the connecting rod 204 drives the piston 206 to move. When the piston 206 moves to a certain distance, the piston 206 will no longer block the air from flowing out of the grip ball 1. The air inside the grip ball 1 will flow out through the holes on the surface of the vent plate 202. The less air inside the grip ball 1, the lower the required pressure will be. After releasing the button 205, the piston 206 will be pushed out by the grip ball. The air inside pushes and naturally blocks the holes on the surface of the vent plate 202 to prevent further air loss. You can put on the device by directly passing your hands through the connecting strap 312 and the second connecting strap 314. If you need to adjust the size of the device, simply pinch the second connecting strap 314 and the connecting strap 312 inward. The second connecting strap 314 will drive the fixing tooth 318 to rotate and disengage from the adjustment groove 313. Then, adjust the fixing tooth 318 to other different positions of the adjustment groove 313 and pass it through to lock it in place with the fixing frame 317. If you need to remove the connecting rope 310, simply press down on the push button 308. After the push button 308 disengages from the fixing groove 304 and no longer locks the mounting groove 302, rotate the mounting block 303 counterclockwise and pull it out from the mounting groove 302.
