Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a medical hand nerve rehabilitation device. Background Art

[0002] Hand nerve rehabilitation refers to the process of gradually recovering the damaged hand nerves through hand exercises after the hand is injured and treated with surgery or other medical means.

[0003] At present, most hand nerve rehabilitation devices on the market are wearable. When in use, other personnel are usually required to tie the base of the rehabilitation device to the patient's arm, and then put the patient's fingers on the finger sleeves on the rehabilitation device one by one. When the patient's hand performs grasping movements, the tension spring on the rehabilitation device can exert a certain pulling force on the bent fingers. In this way, the patient's hand can use greater force in grasping, thereby achieving the effect of exercising the hand nerves. However, the use process of this rehabilitation device is relatively cumbersome, and the patient often cannot complete the wearing process alone, and the disassembly after use is also cumbersome. This situation reduces the use efficiency of the existing hand nerve rehabilitation device. At the same time, this hand nerve rehabilitation device is difficult to clean after use. When the rehabilitation device is used for a long time, a large amount of bacteria or stains will stick to the rehabilitation device, which increases the patient's chance of infection.

The circular mounting groove 2 is connected to the rubber ball 4 through the telescopic pull rod 3 and the rubber ball 4 can be retracted.

[0030] See Figure 2 and Figure 8 , a number of No. 2 telescopic pull rods 5 are evenly inserted on the inner wall of the circular mounting groove 2 and located on the outside of the No. 1 telescopic pull rod, a mobile circular tube 6 is inserted in the circular mounting groove 2, and the end of the No. 2 telescopic pull rod 5 away from the inner wall of the circular mounting groove 2 is fixedly mounted on the corresponding mobile circular tube 6, and the end of the mobile circular tube 6 away from the No. 2 telescopic pull rod 5 is rotatably mounted with a rotating circular tube 7, and the end of the rotating circular tube 7 away from the mobile circular tube 6 is fixedly mounted with a connecting ring 8, and a supporting base cloth 9 made of flexible cloth is fixedly mounted on the inner ring wall of the connecting ring 8, and five finger insertion holes 10 corresponding to each other are opened on the supporting base cloth 9, and five finger cloth covers 11 of a circular tubular structure are fixedly mounted on the side of the support bottom 9 close to the corresponding rubber soft ball 5, and the five finger cloth covers 11 are fixedly mounted with the support bottom 9. The five finger jacks 10 correspond to each other and are connected one by one. Tension springs 12 are fixedly installed on the outside of the five finger cloth covers 11. The ends of the tension springs 12 away from the finger cloth covers 11 are fixedly installed on the inner wall of the rotating circular tube 7. The No. 2 telescopic pull rod 5 is used to connect the movable circular tube 6 and realize its movement in the circular mounting groove 2. The movable circular tube 6 is used to connect the rotating circular tube 7 and realize its rotation. The rotating circular tube 7 tightens the supporting base cloth 9 at the port of the circular mounting groove 2 through the connecting ring 8. When the patient needs to undergo hand nerve rehabilitation, the finger can be directly inserted into the finger jack 10 at the corresponding position and inserted into the finger cloth cover 11. At this time, the finger cloth cover 11 cooperates with the tension spring 12 to perform rehabilitation training on the hand nerves when the patient performs a grasping action.

[0031] See Figure 8 and Figure 9A plurality of positioning slots 13 are provided along the circumference of the connecting ring 8 on the side away from the rotating tube 7, and a fixed ring 14 is provided on the side of the connecting ring 8 away from the rotating tube 7.

The positioning tooth 24 is inserted in the positioning tooth groove 23 at the corresponding position. The connecting block 22 is fixed with an arm bracket 25 by bolts. The arm bracket 25 on the rotating rail is used to support the patient's arm, so that the patient can exert force during hand nerve rehabilitation training.

[0038] See Figure 9 A pressure air pump 26 with suction and inflation functions is fixedly installed on the side of the connecting ring 8 close to the rotating circular tube 7, and a communicating air hole 27 is opened on the connecting ring 8. One end of the communicating air hole 27 is connected to the pressure air pump 26, and the end of the communicating air hole 27 away from the pressure air pump 26 passes through the rotating circular tube 7 and is connected to the closed plastic film 16. The plastic film 16 fixed on the connecting ring 8 can be inflated and inhaled through the pressure air pump 26 and the communicating air hole 27. When the plastic film 16 is installed, the pressure air pump 26 can be used to evacuate the plastic film 16 to fit tightly on the supporting base cloth, so as to prevent the plastic finger cuff 17 from being taken out when the patient pulls out his finger. When the plastic film 16 needs to be replaced, the pressure air pump 26 can be used to inflate the plastic finger cuff 17 and detach it from the finger cloth cover 11.
