Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training device technology, and in particular to a pneumatic manual function rehabilitation training device. Background Technology

[0002] Existing technologies for pneumatic hand function rehabilitation training devices mainly involve pneumatic-assisted medical rehabilitation technology, pneumatic flexible actuators, and pneumatic bionic muscles and elbow joint rehabilitation devices. These technologies utilize pneumatic artificial muscles and pneumatic telescopic tubes, adjusting the length of the tube to change the flexion and extension forces, thus achieving rehabilitation training for the wrist, fingers, and elbow joints. Devices such as intelligent hand function pneumatic rehabilitation training instruments employ end-effector sensing technology, are safe and convenient, and are detachable and washable. Pneumatic muscle-driven gait rehabilitation training exoskeletons have demonstrated effectiveness and safety in gait rehabilitation training. In addition, there are finger rehabilitation training devices based on pneumatic muscles and magnetorheological dampers, as well as methods for manufacturing pneumatic flexion gloves and pneumatic telescopic tubes. These technologies collectively promote the development of rehabilitation training devices, improving the effectiveness and comfort of rehabilitation training.

[0003] Chinese utility model patent application CN219783716U discloses a hand function rehabilitation training device, relating to the technical field of hand function training devices. It includes a hand frame with stretching mechanisms positioned at the corresponding finger positions. Each stretching mechanism includes a mounting frame fixedly mounted on the outer wall of the hand frame. A first mounting box is mounted on the top of the mounting frame, and a second mounting box is mounted on the bottom. This utility model features a hand frame with stretching mechanisms positioned at the positions of the five fingers. Through the interaction of the mounting frame, the first mounting box, the second mounting box, springs, pull ropes, and finger sleeves within the stretching mechanisms, finger flexion training can be achieved. An adjustment component is also included. The position of the second mounting box can be adjusted by the interaction of the adjusting screw and the threaded slider within the adjustment component, thereby compressing or shortening the spring length and adjusting the training intensity of finger flexion. This makes the device suitable for patients in different recovery stages.

[0004] It is evident that the above methods cannot guarantee the effectiveness of rehabilitation training when the hand is in a gripping position, thus reducing the effectiveness of the training. Utility Model Content

[0005] Therefore, this utility model provides a pneumatic hand function rehabilitation training device to overcome the problem that the rehabilitation training effect is reduced when the hand is in a gripping position in the prior art.

[0006] To achieve the above objectives, this utility model provides a pneumatic manual function rehabilitation training device, comprising a support trainer and a controller. The support trainer consists of several separate airbags arranged in a ring shape, several spacer airbags corresponding to the separate airbags, and an inflatable airbag.

[0007] The separating airbag and the corresponding spacer airbag are connected by a connecting tube, and the air pressure is kept consistent in the separating airbag and the spacer airbag. The separating airbag is wrapped around the inner wall of the corresponding support trainer.

[0008] The separation airbag expands in response to the compression state of the corresponding interval airbag, the interval airbag expands in response to the compression state of the inflatable airbag, and the controller inflates the inflatable airbag in response to the decrease in air pressure of the inflatable airbag.

[0009] Furthermore, several annular separation airbags are provided at the end. For a single separation airbag, it consists of a supporting ring and an inflatable ring connected end to end.

[0010] The inner surface radius of the inflatable ring in its uninflated state is set to be on the same ring as the inner surface of the supporting ring.

[0011] The inflatable ring expands when inflated, causing its inner side to expand while its outer side is on the same ring as the outer surface of the supporting ring.

[0012] Furthermore, the spacer airbag is disposed in the middle of the support and fixed at a preset position on the support;

[0013] The spacer airbag is provided with an elastic frame, which maintains its original shape whether it is inflated or not.

[0014] Furthermore, the inflatable airbag is equipped with a one-way valve on the corresponding pipe connected to the controller to maintain the airtightness of the inflatable airbag.

[0015] Furthermore, the controller includes an air pump and a pressure-sensitive switch, wherein,

[0016] The air pump is connected to the inflatable airbag via a connecting pipe;

[0017] The inflatable airbag is equipped with a sensing connection tube connected to the pressure-sensitive switch;

[0018] The pressure-sensitive switch controls the start and stop of the air pump.

[0019] Furthermore, for a single-unit support trainer, it is equipped with at least one separate airbag and one inflatable airbag.

[0020] Furthermore, the separation airbag can be connected to the inflatable airbag via a connecting tube;

[0021] For the detachable airbag connected to the inflatable airbag, the air pressure inside is the same as that of the other parts.

[0022] Furthermore, the position of the spacer airbag between the corresponding separation airbag and the inflatable airbag is adjustable.

[0023] Furthermore, the support trainer is also provided with an external support, which has several segmented spaces inside, and each segmented space can fix the corresponding separation airbag.

[0024] Furthermore, the segmented spaces are set independently, and each segmented space is provided with a corresponding interval line to isolate them from each other.

[0025] Compared with the prior art, the beneficial effect of this utility model is that by setting up several interconnected airbags, the fingers are separated according to the hand movements. By simply controlling the contraction and expansion of the airbags in coordination with the finger ring assembly, rehabilitation training of the hand can be achieved, which can effectively improve the rehabilitation training effect when in a grip position.
