Description

Working method of nursing trolley

Technical Field

The invention relates to the technical field of auxiliary tools, in particular to a working method of a nursing trolley.

Background

For disabled elderly or patients who cannot walk autonomously, nursing staff are needed for nursing, but when the patients need to leave from the bed for toileting or other activities, the nursing staff is needed for assisting the patients, but for the nursing staff, the assistance of the patients to stand up from the bed is not easy.

In order to reduce the nursing difficulty of nursing staff for disabled old people and patients who cannot walk independently, a nursing aid which can help the nursing staff to carry out-of-bed movement on the patients needs to be used and is generally called as a shifting machine. The shifter is mainly used for hospitals and rehabilitation nursing institutions at first and is used for helping patients to shift positions. Existing displacement machines are broadly classified into the following two categories:

(1) hoisting type shifting machine: the shifting machine lifts the patient by the lifting appliance, has simple structure and principle, wide applicable crowd and higher comfort level of the patient. However, the operation of the lifting appliance is complicated, the working efficiency is low, and the patient feels uneasy due to the shaking in the moving process; in addition, the lifting mode of the cantilever is driven by a motor, so that the cost is high and the maintenance is inconvenient. The displacement device is mainly suitable for professional medical care institutions and is not beneficial to popularization and use.

(2) Seat formula machine of shifting: simple to use is convenient, nevertheless is not convenient for take off and wear trousers when like the lavatory, can't use with the wheelchair butt joint, and if chinese patent application number is CN202122500802.7, announcement day is 2022.04.02, it discloses a have over-and-under type aversion car of bed chair function concurrently, specifically disclose: the method comprises the following steps: moving the chassis; the pedal is connected with the movable underframe; the lifting mechanism comprises a main board, a power mechanism, a transmission mechanism, a lifting frame, a handle and an operating button, the two lifting mechanisms are in one-to-one correspondence, the main board is electrically connected with the power mechanism and is internally arranged in the pedal, the transmission mechanism is used for driving the lifting frame to move up and down, and the operating button is arranged on the handle in a penetrating way and is electrically connected with the main board; the seat comprises a first seat frame and a second seat frame which are symmetrically arranged, wherein each seat frame comprises a resistor in sequence

The folding seat cushion comprises a damping hinged first seat cushion plate and a damping hinged second seat cushion plate, and the first seat cushion plate is rotatably connected with the lifting frame. The device has a bed chair function concurrently, and the butt joint sick bed of being convenient for realizes that the patient shifts fast, improves use comfort, and the security is high, labour saving and time saving, long service life, be convenient for operate and accomodate, the device need warp the chair earlier for the shape of bed then remove, but still need earlier to carry out the tie with it to the disease that is in the position of sitting state and lie the state then just remove, produce the influence to hidden danger department easily to make the operation inconvenient.
