Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training technology, and in particular to a bedside training and rehabilitation device. Background Technology

[0002] Traditionally, bed rest was believed to maintain patient strength and promote recovery. However, with the spread of side effects of bed rest, early mobilization has gradually become a new standard of care in ICU. Early mobilization can reduce the occurrence of impaired skin integrity, delirium, and weakness. Increasing research confirms that early and progressive mobilization is feasible, safe, and beneficial for ICU patients, improving their function. Getting out of bed is part of early mobilization, which includes four parts: changing from a lying position to a sitting position, doing exercises at the bedside, sitting in a chair, and standing. To prevent falls and tube dislodgement, significant ICU staffing is often required, thus hindering early mobilization plans due to time constraints, limited ICU staff, and equipment availability.

[0003] However, due to their high cost, body movement motors are often not widely used in ICUs, and overly simple training devices cannot achieve the desired rehabilitation effect for patients' overall coordination, strength, and accuracy. Multiple forms of training are needed to address various aspects such as strength recovery, accuracy, and force exertion. Therefore, this application provides a bedside training and rehabilitation device to meet these needs. Utility Model Content

The protective belt 21 is passed through the patient's arms and the buckle 22 is connected to the patient's chest to reduce the patient's forward tilt due to insufficient upper body support. When the patient exercises his legs, the pin 805 can be disengaged from the rotating sleeve 801 by pulling the sliding ring 802. The pedal device 8 can rotate through the crossbar 7 as the axis. The pin holes of the rotating sleeve 801 are arranged in a ring to lock the pedal device 8, which can adjust the lifting angle of the pedal device 8 to suit different leg lengths of patients. The telescopic frame 808 makes the position adjustment of the pedal device 8 more flexible. When the patient's legs do not need to be exercised, the pedal device 8 can be rotated counterclockwise to be perpendicular to the ground to achieve storage. At the same time, the damper 809 is used to prevent the crank from rotating. The pedaling force can be adjusted by increasing or decreasing the friction by adjusting the contact force between the damper 809 and the brake disc 810, so that the patient can exercise better. The cotton pad 11 and restraint strap 12 limit the patient's arms and can help the patient support the table 1 to exercise the arms to support the body weight. When the patient recovers to a certain level, he can control his body by holding the handrail 4. The binding rope 13 and grip ball 14 can be used to exercise the patient's hand grasping accuracy and strength.
