[0040] See also Figures 1-8, this embodiment proposes a device for assisting forearm function training, including a finger gripping mechanism 1, an airbag inflation mechanism 2 and a forearm covering mechanism 3;

[0041] The finger gripping mechanism 1 is placed on the patient's finger, and is inflated, expanded, and contracted to grip and stretch the patient's palm surface;

[0042] The airbag inflation mechanism 2 injects gas to extend the finger gripping mechanism 1 to expand and contract, and the forearm covering mechanism 3 wraps around the arm to cover the arm;

[0043] The finger gripping mechanism 1 comprises an auxiliary heating pad 11, and a wrist covering band 12 is provided on the side wall of the auxiliary heating pad 11;

[0044] The airbag inflation mechanism 2 is mounted on the top surface of the auxiliary heating pad 11;

[0045] The airbag inflation mechanism 2 includes five inflatable and telescopic airbags 21 attached to the surface of the auxiliary heating pad 11. The inflatable and telescopic airbags 21 are composed of three independent inflatable joints 22. The side walls of each independent inflatable joint 22 are connected to a diverter valve 23, and one end of the diverter valve 23 is connected to a connecting hose 24.

[0046] In this embodiment, finger sleeves 241 are correspondingly mounted on the top surfaces of the plurality of inflatable telescopic airbags 21 , finger insertion openings 25 are opened at the ends of the plurality of finger sleeves 241 , and elastic straps 26 for tightening are bound to the top side of the auxiliary heating pad 11 .

[0047] The elastic belt 26 is tied to the front half of the patient's arm area to make it easier to tighten, and the finger sleeve 241 is used to be put on the person's fingers like a glove.

[0048] In this embodiment, the independent inflatable joint 22 is inflated and telescopically expanded, and a designated circular telescopic slot 27 is opened on the surface of the corresponding independent inflatable joint 22. The auxiliary heating pad 11 and the inflatable telescopic airbag 21 are both shaped like a human palm and have matching sizes.

[0049] The auxiliary heating pad 11 has the effect of utilizing the structure with heating function here to achieve the effect of electrotherapy hot compress when wearing the exercise device.

[0050] In this embodiment: the forearm covering mechanism 3 is covered on the forearm of the person, wherein the forearm covering mechanism 3 includes a wrist covering strap 31 for binding the wrist and the arm, which is attached to one end of the wrist covering strap 12, and the surface of the wrist covering strap 31 is provided with a tightening elastic band 32.

[0051] The wrist wrapping strap 31 and the tightening elastic band 32 are used to achieve a binding connection with the patient's arm.

[0052] In this embodiment, a tightening bandage 33 for tightening is fitted on the middle surface of the tightening elastic band 32 , and a fitting strap 35 for elastic tightening is fitted on the surface of the tightening bandage 33 .

[0053] Improve the binding density with the patient's arm.

[0054] In this embodiment: the surface of the fitting strap 35 is fitted with a sub-magic strip 36 for sewing and pasting, the edge of the sub-magic strip 36 is embedded in the mother magic tape sewn to the inner wall of the fitting strap 35, and the fitting strap 35 is made of elastic material.

[0055] The sub-magic strip 36 binding stage uses Velcro fabric binding effect solution which is more efficient.

[0056] In this embodiment: the outer wall of the finger sleeve 241 is bound with an elastic ring 271, the end of the tightening bandage 33 corresponds to the end position of the wrist covering belt 12, one end of the connecting hose 24 is connected to the inflation mechanism 4, and the inner wall of the fitting strap 35 is embedded with an inflatable covering airbag 37.

[0057] The binding connection between the elastic ring 271 and the tightening bandage 33 ensures that the inflatable covering airbag 37 is in a linked inflated state, which is more reasonable and more efficient.

[0058] In this embodiment, the inflation mechanism 4 includes a frequency inflation pump 41 connected to one end of the communication hose 24 , and a quantitative inflation plate 42 is provided at the middle of the top end of the frequency inflation pump 41 .

[0059] The frequency inflation pump 41 used ensures that the gas delivery solution has more frequency control characteristics.

[0060] Step 1: Insert the finger sleeve 241;

[0061] First, the patient's five fingers are placed into the finger cuff 241 facing the finger insertion opening 25. Then, the cuff 241 is bound to the patient's arm and hand joints based on the internal space. After the patient's fingers are placed, the elastic band 26 is used to fit the hand and tie it to ensure that the hand fits the surface of the wrist cover 12.

[0062] Step 2: heating;

[0063] During this period, the temperature rise is controlled by the electric heating wire embedded in the auxiliary heating pad 11. After the temperature rises, it is conducted to each independent finger cuff 241 area. In addition, the heat is controlled and continuously lower than the tolerance range of each airbag. The heated finger cuff 241 is more comfortable to use.

[0064] Step 3: Finger rehabilitation exercises;

[0065] Background: Due to brain damage or finger and palm nerve damage, patients have difficulty making or opening their fists. This is why this type of exercise program has been developed to improve patients' arm grip.

[0066] After the finger is inserted, the tightening bandage 33 is tied to the patient's forearm wrist and the first movable joint area, and then tightened like a Velcro band for measuring blood pressure. The tightening bandage 33 is used to lift the binding stage and bind it to the patient's arm. After the specific binding, the frequency inflator 41 is used to supply gas. After the supply is completed, the gas bag of the inflatable covering airbag 37 is expanded to form a bulge, which covers and squeezes the part of the joint between the wrist and forearm movable joint;

[0067] dilate blood vessels;

[0068] Step 4: Gas rushes in and simulates the finger clenching and stretching state;

[0069] The key technical point is to turn on the frequency inflation pump 41 with frequency inflation function. At this time, gas will be input along the connecting hose 24. The gas delivery scheme will make each cuff 241 gradually realize frequency inflation extension and deflating contraction of the independent inflation joint 22 at the patient's joint.

[0070] The principle of this behavior is that the gas will be diverted to the special diverter valve 23, and different amounts of gas will be gradually injected into each joint. At this time, the multiple contraction grooves on the surface of the inflatable and telescopic airbags 21 injected with gas will expand gradually outward due to the change in air pressure.

[0071] After the expansion is complete, the fingers 241 will gradually extend. This extension will cause the fingers 241, which were initially in a fist state, to gradually expand and stretch outward, simulating the entire movement process of the fingers of a human hand, from initially clenching the fist toward the palm, to slowly stretching, and then to gradually straightening. This process is used to help people who have undergone brain surgery and have varying degrees of difficulty controlling one side of their hand.

[0072] Step 5: Frequency setting to complete the frequency control of gas inflation and suction;

[0073] The frequency air pump 41 (xdb-001) used has the characteristics of frequency switch control, inflation and exhaust in one, and the final technical stage of perfection is coordinated with the suction function in cooperation with the grip and extension of human fingers, that is, under a certain frequency control, it can inflate, extend and then contract every minute.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
