Description

Technical Field

[0001] The invention relates to the field of medical nursing equipment, in particular to a wrist joint protection and fixing device. Background Art

[0002] In order to speed up the recovery of the wrist joint after treatment of wrist injury, doctors generally use auxiliary tools to restrict the patient's wrist to prevent wrist movement. With the improvement of medical level, most of the auxiliary tools are easy to wear and lightweight tools. Currently, wearable protective covers are commonly used. This kind of protective cover can be directly worn on the wrist to protect the wrist, which is very convenient to use. A Chinese patent discloses a wrist joint fixation device (authorization publication number CN219000795U). The arm surface fixation plate and the arm side fixation plate in the patent are arranged around the arm to improve stability, which is conducive to the rehabilitation of distal radius fracture displacement. The airbags arranged on the inner surface of the arm side fixation plate and the arm surface fixation plate further improve the stability of the wrist joint fixation device and the flexibility of adjusting the tightness, which is helpful for local swelling reduction. However, neither the existing protective sleeve nor the fixation device disclosed in the patent has the function of self-adjustment and reminder according to the swelling of the patient's arm. The injury to the wrist is quite special. After the wrist injury is treated and fixed, it does not mean that the wrist will not swell again. After the patient inadvertently moves the wrist, the wrist is very likely to swell again. Especially if the swelling problem is not discovered in time when the patient is in a sleeping state, the patient's wrist will be squeezed by the fixation device and the problem of osteofascial terminal syndrome will occur, resulting in further deterioration of the condition of the wrist or even the arm. Therefore, the present invention provides a wrist joint protection fixation device to solve the above-mentioned problems. Summary of the invention

[0003] The purpose of the present invention is to provide a wrist joint protection and fixing device to solve the problems raised in the above background technology.

[0011] As a further solution of the present invention, a plurality of damping springs are fixedly connected to one end of the buffer disk away from the sleeve, a water storage pipe is also fixedly connected to the outer wall of the outer shell, and a guide pipe is fixedly connected to one end of the water storage pipe away from the outer shell, and a storage disk is magnetically connected to the lower end of the guide pipe. The storage disk penetrates the outer wall of the protective shell and is adsorbed on the lower end of the guide pipe, and a medium that absorbs heat when it comes into contact with water is stored in the storage disk, and a water adding pipe for adding water to the storage disk is installed in the water storage pipe.

[0012] As a further solution of the present invention, the interior of the outer shell is also rotatably connected with a transmission structure for providing power to the water filling pipe, the transmission structure includes a power gear, the lower end of the power gear is meshed with a rack, the rack is fixedly connected to the buffer disk, the power gear is meshed with a pinion on the side away from the buffer disk, the outer wall of the pinion is fixedly connected with a rotating disk, and the rotating disk is rotatably connected to the water filling pipe.

The water outlet is located in the guide pipe. A push rod is slidably connected in the absorption pipe. The outer diameter of the push rod is adapted to the inner diameter of the absorption pipe, and the push rod is rotatably connected to the rotating disk.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. When the user's wrist or forearm swells during use of the present invention, the inner sleeve will have a tendency to expand outwards. At this time, the inner sleeve will pull the piston in the first hydraulic pipe to move so that the solution medium in the first hydraulic pipe enters into the second hydraulic pipe, and then the solution medium in the second hydraulic pipe enters into the release pipe to change the size of the first rubber bag and the second rubber bag, so that both the outer reserved band and the inner reserved band can be expanded, thereby preventing the inner sleeve and the outer sheath from compressing the user's swollen arm, thereby preventing the user from suffering from osteofascial syndrome.

[0015] 2. When the present invention is used, the winding shell will push the moving block during the downward movement, so that the buffer disk pushes the rack to drive the power gear to rotate, and the rotating disk drives the push rod to move back and forth. During the back and forth movement of the push rod, the absorption tube will absorb water and discharge water, so that water enters the storage disk through the guide tube, so that the medium in the storage disk that absorbs heat when encountering water combines with water to absorb heat, and then the storage disk becomes cold, thereby reminding the user that the arm is swollen and needs to be treated in time.

[0030] The working principle of the present invention is: When the present invention is used, the arm is first placed in the inner sleeve 3 and then the tightness of the outer sleeve 2 is adjusted directly with the Velcro 4. When the tightness of the outer sleeve 2 is adjusted to a suitable state, the limiting disk 503 is pulled away from the winding shell 502 to rotate the winding shaft to adjust the tightness of the inner sleeve 3, so that the inner sleeve 3 fits the forearm of the arm. In this way, the outer sleeve 2 and the inner sleeve 3 can be worn; When the user's wrist swells at night, the swollen skin will cause the inner sleeve 3 to tend to expand outwards. However, since the inner sleeve 3 is not elastic, the inner sleeve 3 can only pull the reel shell 502 to move downward. When the reel shell 502 moves downward inside the protective shell 500, it will drive the solution medium in the first hydraulic tube 504 to enter the second hydraulic tube 505 through the connecting soft rope, so that the solution medium in the second hydraulic tube 505 enters the release tube 7. Since the inner diameter of the second hydraulic tube 505 is larger than the inner diameter of the first hydraulic tube 504, the second hydraulic tube 505 will amplify the thrust generated by the first hydraulic tube 504, so that the solution medium in the second hydraulic tube 505 enters the release tube 7 more forcefully, thereby pushing the push block 701 to move in the direction of the first rubber bag 702. The pushing block 701 will push the solution medium in the release tube 7 to move during its movement, thereby using the solution medium to push the first blocking block 703 to slide. After the first blocking block 703 slides, it will compress the limiting spring 704. The limiting spring 704 is compressed so that the solution medium in the first rubber bag 702 will flow into the release tube 7 (the compression of the first blocking block 703 will increase the storage space in the release tube 7, thereby allowing the solution in the first rubber bag 702 to have space to flow out). After the solution medium in the first rubber bag 702 flows out, the first rubber bag 702 will shrink. At this time, the first rubber bag 702 will pass through the connecting circular hole of the closest first rubber bag 702, thereby stretching the outer reserved belt 202 for a distance, thereby expanding the outer sheath 2. When the contraction resistance of the limiting spring 704 increases to a certain extent, the second blocking block 705 will move to push the solution medium between the second blocking block 705 and the third blocking block 707, thereby shrinking the second rubber bag 706, so that the inner reserved band 301 stretches a distance, so that the outer sheath 2 and the inner liner 3 can be expanded, thereby preventing the user from suffering from osteofascial syndrome due to the squeezing of the inner liner 3 and the outer sheath 2 due to the swelling of the arm, and the inner liner 3 expands later than the outer sheath 2 to avoid the problem that the outer sheath 2 has no time to expand; In the process of the winding shell 502 moving downward, it will also push the moving block 610, so that the buffer disk 605 pushes the rack 611 to drive the power gear 612 to rotate, so that the rotating disk 613 drives the push rod 903 to move back and forth. In the process of the push rod 903 moving back and forth, the absorption tube 900 absorbs water and discharges water, so that the water enters the storage disk 10 through the guide tube 8, so that the medium in the storage disk 10 that absorbs heat when encountering water combines with the water to absorb heat, and then the storage disk 10 becomes cold, thereby reminding the user that the arm is swollen and needs to be treated in time (it is worth noting that It is worth noting that since the outer sleeve of the absorption tube 900 is provided with a corrugated sleeve, the compression and extension of the corrugated sleeve are both limited by distance, so the movement stroke of the absorption tube 900 is fixed, so the push rod 903 moves back and forth to allow the absorption tube 900 to pump and drain water, and the absorption tube 900 will not always follow the movement of the push rod 903, resulting in the problem of being unable to pump and drain water. At the same time, it is worth noting that when a person is asleep, the skin senses are still in a working state, and when suddenly contacting with a cold object, it will give feedback to the brain in time, so that the user can feel the reminder in a short time); In order to ensure that enough water enters the storage disk 10, the limiting head 604 moves to the vicinity of the magnet ring 607 and is adsorbed to separate from the inner diameter tube. At this time, the damping spring 608 begins to release pressure to push the buffer disk 605 to reset. During the reset process of the buffer disk 605, the absorption tube 900 can still be driven to work. Moreover, the buffer disk 605 will slow down the reset speed under the action of the flow port 606, thereby avoiding the problem that the absorption tube 900 cannot pump water or drain water normally due to the reset being too fast. When the outer sheath 2 and the inner liner 3 are removed, the entire device will return to its original state under the action of several springs. At this time, you only need to manually pass the connecting circular holes on the outer reserved belt 202 and the inner reserved belt 301 through the first rubber bag 702 and the second rubber bag 706 for next use. When it is necessary to replace the medium that absorbs heat when encountering water in the storage disk 10, the storage disk 10 can be removed and filled with new medium.
