Description

A kind of auxiliary device for orthopaedic rehabilitation

technical field

The invention relates to the technical field of medical devices, in particular to an auxiliary device for rehabilitation of orthopedics.

Background technique

Orthopaedic rehabilitation refers to the rehabilitation of the affected part of orthopedic patients, so as to achieve rapid recovery of the affected part of the patient and reduce the pain of the patient during the treatment process. In the traditional orthopedic treatment process, orthopedic patients often only need to lie on the hospital bed and wait for recovery after the operation, but a series of problems will occur during this process. There are too many patients in the hospital and they need to lie down. Patients treated in hospital beds cannot receive effective treatment, which greatly exacerbates the problem of tension between doctors and patients. In the process of resting in the hospital bed, the patient will recover slowly due to long-term bed rest. On the other hand, the patient's long-term bed rest will cause the patient to suffer from bed sores and other diseases, making the patient's treatment process more painful, and greatly prolonging the patient's healing time. Therefore, auxiliary devices need to be used in the rehabilitation process of orthopedic patients to solve the above problems; the application of rehabilitation equipment assists patients in various exercises, but the current exercise devices can only exercise the upper or lower limbs of patients, and cannot exercise at the same time. Therefore, The inability to effectively exercise the coordination of the limbs of orthopaedic patients will easily lead to the need for a period of time for orthopedic patients to perform physical coordination exercise after discharge. At the same time, limb exercise also avoids patients only exercising the upper or lower limbs and ignoring the exercise of other parts during the illness. This can lead to problems such as muscle atrophy in other parts. On the other hand, when the patient has been lying in the hospital bed for a long time, massaging the contact area during exercise will prevent the occurrence of bedsores, which can greatly speed up the patient's recovery process and shorten the patient's treatment cycle. To a certain extent, it can solve the problem of tension between doctors and patients in hospitals.
