Description

Adjustable angle and high and low position stand

The present invention relates to a standing frame, and more particularly to a standing frame for assisting a patient such as cerebral palsy, muscular dystrophy or other patient unable to control body movements in a relatively stable standing position.

Patients such as cerebral palsy and muscular dystrophy cannot control the movement and balance of the body autonomously. Therefore, some patients with more serious problems may have problems in which they cannot maintain their standing posture. For this reason, some practitioners have developed a method to assist the patients. A standing frame that is relatively stable and maintains a standing position. The bottom of the stand is provided with wheels, so that the caregiver can push the patient to move. The stand may typically include a support plate for securing the patient's body, and the support plate may be adjusted to remain substantially perpendicular or perpendicular to the ground, in which state the patient can be supported by the stand In keeping with the standing posture, the support plate can be further adjusted to be substantially parallel to the ground. In this state, the standing frame has the function of a bed, and the patient can rest on the standing frame.

Although the support plate of the conventional standing frame can be adjusted, the patient fixed on the support plate increases the overall weight and the adjustment of the support plate does not have an auxiliary push design, so the body adjustment is required by the caregiver alone.
