Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to an arm grip strength recovery device for fracture rehabilitation training. Background Art

[0002] After fracture treatment is completed, the arm will suffer certain functional damage, so grip strength training is required to restore arm movement.

[0003] In the use of existing grip strength recovery devices, there is no protective structure connected to the back of the hand. Therefore, once it falls off during gripping, it is easy to cause damage to the device accidentally dropping, and may also affect the patient's hand. So there are great limitations in actual use and there is room for improvement. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an arm grip strength recovery device for fracture rehabilitation training to solve the problem that the existing grip strength recovery device does not have a protective structure as mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An arm grip strength recovery device for fracture rehabilitation training, including a connecting block; a finger pressing plate arranged on the top of the connecting block, and a connecting spring one is connected between the two; a plurality of palm pressing blocks are arranged at the bottom of the connecting block, and a connecting spring two is connected between the two; a protective component is further included, and the protective component is composed of a connecting piece and a protective piece. The connecting piece is connected to the connecting block, and both ends of the protective piece are installed on the connecting piece, and the protective piece is sleeved at the position of the back of the human hand, so as to realize the connection of the whole recovery device. Even if the fingers, palm and the recovery device become loose, the problem of the whole recovery device falling will not occur.

[0006] Preferably, a placement groove is opened on the rear surface of the connecting block. The connecting piece includes a mounting plate placed in the placement groove. A pressing plate is arranged at the top of the placement groove, and a plurality of pressing springs are fixed between the pressing plate and the top of the placement groove. The pressing plate abuts against the mounting plate; at equal intervals at the bottom of the outer surface of the mounting plate, alignment grooves are opened, and a limiting convex block is fixed at the opening edge of the bottom of the placement groove. The limiting convex block is engaged with the alignment groove to realize the fixed connection between the mounting plate and the connecting block and avoid separation.

[0007] Preferably, a card slot is opened on the top end surface of the mounting plate, and an insertion plate is fixed at the bottom end surface of the pressing plate. The insertion plate is engaged with the card slot to realize the limiting and fixing of the top position of the mounting plate.

[0008] Preferably, the bottom corners of the pressing plate facing the outside of the connecting block are inclined, which facilitates the pushing-in of the mounting plate. The pressing plate is hook-shaped, and the pressing spring is located inside the pressing plate. Therefore, during the compression of the pressing spring, the pressing plate can completely cover the pressing spring, and the top end of the pressing plate itself fits against the inner top surface of the placement groove.

[0009] Preferably, the sum of the width of the mounting plate, the height of the limiting convex block, and the height of the pressing plate and the insertion plate is equal to the inner height of the placement groove. That is, during installation, first press the top of the mounting plate against the pressing plate, and simultaneously push the limiting convex block in. At this time, the pressing spring rebounds, causing the pressing plate to press the mounting plate downward, and the alignment groove is penetrated by the limiting convex block, achieving a firm connection.

[0010] Preferably, the protective member is a connecting belt, and both ends of the connecting belt are heat-melted and installed on the outer surface of the mounting plate.

[0011] Preferably, a tightening portion is formed in the middle of the connecting belt, which can adjust the length of the connecting belt. The thickness of the mounting plate is equal to the inner depth of the placement groove.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] Through the designed protective component, the grip strengthener can be sleeved on the back of the hand, thus facilitating normal exercise, avoiding the harm caused by accidental loosening, and at the same time, the protective structure can be disassembled and replaced according to needs, with relatively high overall flexibility, improving the deficiency of the existing structure in terms of safety.
