Description

A posture assisting device for rehabilitation of patients with heart failure

Technical field:

The present invention belongs to the technical field of medical rehabilitation equipment, and in particular relates to a posture assisting device for rehabilitation of patients with heart failure.

Background technique:

Heart failure is the terminal stage of most cardiovascular diseases and the most common reason for hospitalization in the elderly over 65 years old. Patients with heart failure often sit or lie in a semi-recumbent position to reduce venous return in the patient's lower limbs, reduce the heart load, and alleviate their symptoms. Patients with heart failure are generally older. If they do not use auxiliary devices to fix their position and improve the compression of the sacrum and coccyx, they are prone to pressure sores, body tilt and slide, fall from the bed, or fall when they get out of bed on their own during the semi-recumbent process, which increases the burden on caregivers and family members. Therefore, the patient needs to be fixed in position.

At present, the method of fixing the body position of heart failure patients in clinical practice is mostly the belt fixation method, which places the patient's limbs or trunk in a certain fixed facility, connects the facility with an extension belt, and ties it to the edge of the bed. However, this method of fixation will result in a small range of patient movement and limited mobility. At the same time, the patient cannot adjust his or her body position by himself or herself, and family members need to untie the belts to go to the toilet or change position, which increases the burden on family members and caregivers. In addition, patients are in bed resting or semi-recumbent positions for a long time, and skin abrasion and pressure sores may occur on the sacrum and coccyx. When the patient falls out of bed or gets out of bed on his or her own, the patient's out-of-position information cannot be transmitted to the caregiver, resulting in the caregiver being unable to stop the patient's actions in time.

Summary of the invention:

The present invention provides a posture assist device for the rehabilitation of heart failure patients, which aims to solve the problems that the existing strap fixation will result in a small range of patient body activities, relatively restricted movements, and the patient cannot adjust the body position by himself. Family members need to untie the straps when going to the toilet or changing body positions, which increases the burden on family members and nursing staff, and the patient is in a semi-recumbent position for a long time, which may cause skin abrasion and pressure sores on the sacrum and coccyx, and the patient's out-of-position patient information cannot be transmitted to nursing staff, resulting in the nursing staff being unable to stop the patient's movements in time.
