Description

A wrist rehabilitation device

Technical field

The present invention relates to the technical field of medical devices, and more specifically, to a wrist rehabilitation device.

Background technique

During sports, the movements of the wrist joint are quite complex and delicate, so they are also very susceptible to injury. The manifestations of wrist injuries are diverse, ranging from acute injuries to ligaments, tendons, bones and joints to chronic strain injuries. It is more common in basketball, volleyball, badminton, weightlifting and other sports, accounting for about 6% of sports injuries. Wrist injuries are more common in mass fitness activities. For example, when playing badminton, whether it is hitting, smashing, hanging, picking, pushing, diving, or hooking, the wrist is required to extend and abduct. Wrist injuries may result from irregular movements, improper use of force, or lack of warm-up.

During the rehabilitation phase after a wrist injury, wrist joint exercises are generally carried out with the help of corresponding devices.

S5. Drying: Place the adjustment rod 331 obtained in S4 inside the oven, and dry it for 8 hours in a 40°C environment.

In this embodiment, because the adjustment hole 335 and the fixed fitting rod 34 cooperate to achieve forearm fixation for patients with different forearm thicknesses, once the adjustment hole 335 is seriously worn, the aperture of the adjustment hole 335 will become larger, so that the fixed rod and the adjustment hole 335 can be matched will loosen, which will affect the fixation effect of the forearm, and may reduce the targeted exercise effect of the wrist. Therefore, coating the adjustment rod 331 with a wear-resistant layer can slow down the adjustment rod 331, especially the adjustment hole 335. wear, ensuring the fixation effect on the forearm, thereby ensuring the targeted exercise effect of the wrist, helping to shorten the recovery cycle.

Example 3

The difference from Example 2 is that the formula specific gravity of the wear-resistant layer is modified. The modified preparation method is:

Take the following raw materials by weight for later use: 7 parts of quartz powder, 11 parts of chromium powder, 8 parts of diatomaceous earth, 22 parts of molybdenum powder, 15 parts of thermoplastic water-based polyurethane, 4 parts of ethylene oxide, 42 parts of cobalt powder, 15 parts of sodium bentonite, 4 parts of furfural resin and 80 parts of ethanol.

S1. Premade organic solvent: Mix thermoplastic water-based polyurethane, ethylene oxide, furfural resin and ethanol, and stir evenly;

S2. Preparation of wear-resistant materials: Add quartz powder, chromium powder, diatomaceous earth, molybdenum powder, cobalt powder and sodium bentonite to the organic solvent in S1. After stirring evenly, heat the temperature to 75°C and keep it warm for 4 hours;

S3. Cleaning: Use additional ethanol to clean and decontaminate the adjustment rod 331;

S5. Drying: Place the adjustment rod 331 obtained in S4 inside the oven, and dry it for 8 hours in a 40°C environment.

In this embodiment, only the proportions of the formula ingredients are adjusted for comparison to obtain the optimal formula.

Example 4

The difference from Example 2 is that the formula specific gravity of the wear-resistant layer is modified. The modified preparation method is:

Take the following raw materials by weight for later use: 6 parts of quartz powder, 9.5 parts of chromium powder, 7 parts of diatomaceous earth, 21 parts of molybdenum powder, 13 parts of thermoplastic water-based polyurethane, 3.5 parts of ethylene oxide, 40.5 parts of cobalt powder, 12.5 parts of sodium bentonite, 3 parts of furfural resin and 75 parts of ethanol.

S1. Premade organic solvent: Mix thermoplastic water-based polyurethane, ethylene oxide, furfural resin and ethanol, and stir evenly;

S2. Preparation of wear-resistant materials: Add quartz powder, chromium powder, diatomaceous earth, molybdenum powder, cobalt powder and sodium bentonite to the organic solvent in S1. After stirring evenly, heat the temperature to 75°C and keep it warm for 4 hours;

S3. Cleaning: Use additional ethanol to clean and decontaminate the adjustment rod 331;

S4. Spraying: Hang the adjusting rod 331 in the paint room, and use an atomizer to evenly spray the wear-resistant material obtained in S2 onto the adjusting rod 331, especially into the adjusting hole 335;

S5. Drying: Place the adjustment rod 331 obtained in S4 inside the oven, and dry it for 8 hours in a 40°C environment.

In this embodiment, only the proportions of the formula ingredients are adjusted for comparison to obtain the optimal formula.

By using a rotary machine tool to hold the fixed fitting rod 34 and rotate it at a constant speed in the adjustment hole 335 on the adjustment rod 331 at a slow speed, the wear resistance strength of the adjustment rod 331 is estimated by measuring the hole diameter at the end, and the adjustment rod 331 is 331 is hung in a high-temperature room, and after being placed for a sufficient period of time, the wear-resistant layer on the surface of the adjusting rod 331 is peeled off through a magnifying glass to estimate the anti-falling strength of the adjusting rod 331. Embodiments 1, 2, and 3 are , the adjusting rod 331 in different situations in 4 was tested, the four sets of data obtained were normalized based on Example 1, and comparative analysis was performed, as shown in the following table,

Wear resistance Anti-falling strength Example 1 100% 100% Example 2 182% 159% Example 3 185% 134% Example 4 184% 152%

Because the adjustment hole 335 and the fixed fitting rod 34 cooperate to achieve forearm fixation for patients with different forearm thicknesses, once the adjustment hole 335 is seriously worn, the aperture of the adjustment hole 335 will become larger, so that the fit between the fixed rod and the adjustment hole 335 will become loose. , which in turn affects the fixation effect on the forearm, and may lead to a reduction in the targeted exercise effect of the wrist. Therefore, coating the adjustment rod 331 with a wear-resistant layer can slow down the wear of the adjustment rod 331, especially the adjustment hole 335, and ensure that the forearm is protected. The fixation effect ensures the targeted exercise effect of the wrist and helps shorten the recovery cycle. From the data in the table, it can be seen that after coating the wear-resistant layer, the wear-resistant strength of the adjustment rod 331 has been significantly enhanced. At the same time, combined with the wear-resistant After a comprehensive analysis of the anti-falling strength of the grinding layer, Example 4 has the best effect, so the optimal formula is: 6 parts of quartz powder, 9.5 parts of chromium powder, 7 parts of diatomite, 21 parts of molybdenum powder, 13 parts of thermoplastic water-based polyurethane 3.5 parts of ethylene oxide, 40.5 parts of cobalt powder, 12.5 parts of sodium bentonite, 3 parts of furfural resin and 75 parts of ethanol.

It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are to distinguish two entities or parameters with the same name but not the same, so it can be seen that "first" and "second" It is only for the convenience of description and should not be understood as a limitation on the embodiments of the present invention. This will not be described one by one in the subsequent embodiments.

This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention.
