Wheelchair external fixing device suitable for muscle-bone ultrasonic examination of stroke patient

Abstract

The wheelchair external fixing device comprises a connecting frame, a fixing plate, a lifting plate, a rotating plate, a sliding plate and a hand rest, the fixing plate is connected with the connecting frame, the fixing plate is connected with the lifting plate, a lifter is arranged between the fixing plate and the lifting plate, the lifting plate is connected with the rotating plate, and the rotating plate is connected with the sliding plate. A rotating motor, a gear and a gear ring are arranged between the lifting plate and the rotating plate, a guide rail is arranged on the rotating plate, the sliding plate is connected with a sliding block on the guide rail, and a stepping motor and a ball screw nut pair are arranged between the rotating plate and the sliding plate. The rotating motor, the stepping motor and the electric inflator pump are controlled through the controller, automatic movement of the wheelchair external fixing device in multiple directions is achieved, the wheelchair external fixing device is particularly suitable for body position control during muscle-bone ultrasonic detection on a stroke patient, the labor intensity of a doctor for searching for an articular cavity is reduced, the medical efficiency of the doctor is improved, and the medical effect of the doctor is improved. The recovery of the affected limb of the stroke patient is also facilitated.

Description

technical field [0001] The invention relates to the technical field of wheelchair assistance, in particular to a wheelchair external fixation device suitable for musculoskeletal ultrasonography of stroke patients. Background technique [0002] At present, the prevalence of stroke is increasing year by year as a whole, and post-stroke hemiplegia is one of the most common dysfunctions, and wheelchairs have become the main travel tool for stroke patients. Hemiplegia in stroke patients can lead to various complications, among which shoulder-hand syndrome is more common. Shoulder-hand syndrome refers to the sudden swelling and pain of the patient's hand and shoulder joint pain, and the hand function is limited. Due to severe pain and twins, it has become an obstacle to rehabilitation. [0003] In the prior art, more and more rehabilitation physicians use musculoskeletal ultrasound technology to check and understand the shoulder condition caused by shoulder subluxation in stroke ...

AI Technical Summary

Problems solved by technology

[0004] The problem existing in the prior art is: because the function of the upper limbs of stroke patients after hemiplegia is constantly changing, and with the prolongation of the disease, the degree of shoulder subluxation of the same patient will also change. Therefore, shoulders in different stages For patients with joint subluxation, the most suitable angle of the shoulder joint is different based on the musculoskeletal ultrasound examination. Most stroke patients cannot maintain the proper height or position of the affected shoulder during the ultrasound examination, which requires doctors and others to conduct the examination. Auxiliary positioning makes it difficult for the doctor to understand the patient's shoulder condition, and is not conducive to the doctor's operation and diagnosis of the patient's ultrasound examination, and even affects the follow-up treatment of the patient's disease, while increasing the doctor's labor intensity; in addition, the doctor finds the patient. It takes a lot of time and energy to get the upper limbs in a proper position, which leads to a long time for a single patient, low work efficiency, and a small number of patients every day, which affects the diagnosis and rehabilitation of follow-up patients; the usual wheelchair armrest height It is inconvenient to adjust the position and position, which is not conducive to keeping the patient's arm in the required position, and it is not conducive to the rehabilitation of the affected limb after long-term use
