Description

Posture transition aids

The present invention relates to an auxiliary tool for posture conversion, in particular to an auxiliary tool for assisting patients who cannot move voluntarily to change between lying posture, sitting posture and standing posture.

At the end of March 2017, my country's household registration registered 3.31 million people over the age of 65, accounting for 14.1% of the total population, officially entering the "senior society". Among them, as early as 2016, 60% of the disabled elderly in Taiwan were cared for by their family members. Looking at the previous care aids and related technologies for the disabled, we found that many equipment mechanisms are too complicated, and it is indeed inconvenient and difficult for a single person to operate. At the same time, among the numerous existing inventions, few getting up aids can achieve the function of converting a patient from a lying position to a sitting position, but simply change between sitting position transfer tools. Finally, the present invention also does not contain electrical related operation dependencies, so that the overall mechanism is simple and convenient, and can be applied in any environment.

The present invention is an auxiliary tool for posture conversion, which aims to assist patients who cannot move autonomously to convert between lying, sitting and standing postures, so as to facilitate the transition from bed to wheelchair and other vehicles. The posture conversion aid of the present invention includes four structures, and the first three structures are used for the upper body, thigh, and lower body of the patient, respectively. The three parts of the legs are leaning and sitting to support the weight of the patient. One-way pivoting devices, such as a ratchet mechanism and a sheave mechanism, are used between the three structures to assist the operator in changing the patient's posture and angle. The fourth structure is the base plate that facilitates the patient's footing and gravity support. The above-mentioned four-stage structure will be described in detail below.

The structure of the posture conversion aid of the present invention includes four parts: (1) an upper body support frame and a backboard for supporting the patient's back and leaning on, (2) a cushion plate for bearing the weight of the patient's buttocks, and (3) a calf supporting the patient's calf A support plate, (4) a foot support pad for facilitating the patient to stand on, and a gravity support plate for stabilizing the center of gravity when changing postures. Between each connecting surface, pivoting devices are used to support the movement of the skeleton. The upper body support frame and the cushion plate are connected and can be flattened or folded mutually along the first pivoting device. Positionable rotating parts, such as ratchet mechanism and sheave mechanism, are used at the joint, so the upper body support frame and the cushion plate can be folded to any position. need to be angled and fixed so that it only rotates in one direction. The purpose of using this rotating mechanism is that when the user wants to lift the patient up from the bed, he only needs to apply force to the assistive device in one direction, and the rotating mechanism will rotate in the opposite direction according to the gear structure, while supporting the weight of the patient. The body rolls back. The pivoting device used in the present invention has the function of changing the direction of rotation, that is, the difference between forward rotation, reverse rotation and idle rotation. The operator only needs to adjust the rotary switch to make the structure of different sections rotate in the direction of the operator's wishes.
