Description

Shoulder joint anterior dislocation chair that resets

Technical Field

The utility model relates to the technical field of joint rehabilitation assistance, in particular to a reduction chair for shoulder joint anterior dislocation.

Background

The hand-foot-pulling method is a classic method for treating the shoulder joint dislocation in a professional book, requires cooperation of multiple persons, consumes a large amount of physical strength in the reduction process, may cause complications such as fracture, nerve injury and the like, and may also fail to reduce. The single chair back method for resetting the anterior dislocation of the shoulder joint has the advantages of simple operation, single independent completion, difficult generation of complications such as fracture, nerve injury and the like, and especially obvious advantages for the resetting by the single chair back method under the condition that the old people are not suitable for the foot-pulling and pedaling method by hands.

After consulting documents, doctors adopt household wooden back-rest chairs in most cases; the reset chair designed by other people also has complex design and generally does not have a rollover prevention design, and the chair can be overturned and toppled over when an operator performs lateral forced traction, so that certain problems exist in safety.

The prior patent (publication number: CN 209107968U) discloses a chair capable of repositioning the front dislocation of the shoulder joint, which can be provided with a sliding chair back, wherein a sliding rod is arranged on the sliding chair back, a sliding groove matched with the sliding rod is arranged on the chair back, the sliding rod can slide up and down along the sliding groove, and the sliding rod can drive the height adjustment between the sliding chair back and the whole chair back by driving along the up and down sliding of the sliding groove; the first positioning pin is sequentially inserted into the second fixing pin hole and the first fixing pin hole, so that the sliding chair back is fixed on the chair back, and the height between the sliding chair back and the whole chair back is adjusted and then fixed. Dislocation chair that resets before the shoulder joint after the improvement, still set up in supporting the extension rod, the bottom of chair leg sets up in supporting extension rod slip through-hole, the one end of supporting the extension rod is arranged in and is supported extension rod slip through-hole, it slides along supporting extension rod slip through-hole to support the extension rod, when supporting in the extension rod stretches out and supports extension rod slip through-hole, the second locating pin is inserted in the third fixed pin hole in proper order, the fourth fixed pin hole, can be so that support the extension rod and be fixed in chair leg bottom, the effect of preventing dislocation chair that resets and turn on one's side before the shoulder joint has, the height of the back of the chair is conveniently adjusted in single bare-handed resetting, the effect of preventing turning on one's side has simultaneously, very big market application and spreading value have.

However, the reduction chair for anterior dislocation of shoulder joint has some disadvantages in practical application: when the dislocation reset chair designed as above is used for adjusting the back of the sliding chair, the positioning pin needs to be taken out firstly, then the sliding chair back vertically slides up and down, when the sliding chair back slides to a proper height, the positioning pin is used for inserting and positioning the sliding chair back, the process is complicated, the height of the sliding chair back cannot be quickly adjusted, and because the distance exists between the two hole positions, so that the sliding chair back can not be precisely adjusted in height, and the practicability is further reduced, although the problems of the prior few reset chairs which can rapidly adjust the height of the sliding chair back are solved, most of the prior reset chairs are not provided with a positioning mechanism, because the prior reset chair for quickly adjusting the height of the sliding chair back drives the internal lifting structure by the turntable, if the positioning structure is not arranged, the turntable is likely to rotate, therefore, the reduction chair for the shoulder joint anterior dislocation is designed to solve the problems.
