Abstract

The utility model relates to a hand lifting mechanism for a patient moving, mainly comprising a slide seat, a lifting element and a drive part. The utility model can slide along the upright post of a moving device by the slide seat. One end of the slide seat is pivoted with the pressing cylinder of the moving device. The cylinder shaft tail end of the pressing cylinder is pivoted with a hanging rod, wherein, the tail end of the hanging rod is provided with a clothes hanging frame for hanging the patient. The other end of the slide seat is screwed with the lifting element, and the top end of the lifting element is connected with the driven element of the drive part so that the lifting element is driven by a drive element. The screwing operation of the lifting element drives the slide seat to lift by the gear transmission of the drive part so that the utility model can meet the requirements of normal lifting displacement by hand maintaining under the failure state of a power source.

Description

The manual lifting mechanism of patient shifting device

This utility model relates to a kind of manual lifting mechanism of patient shifting device, relates to area of medical devices.

Cause the existing numbers of can not ignore of inconvenient actors such as health paralysis or deformity in recent years owing to apoplexy, traffic accident, special disease, and look after these patient's not a duck soups, especially the moving process of patient between wheelchair, sick bed, bath lavatory, all be to rely on manually to do, particularly painstaking especially to the heavier patient of body weight, it is improper to move, and hurts patient or bearer's waist easily, and patient more can produce the problem that wound enlarges if decubital ulcer is arranged when moving.

Therefore develop the shift unit that a kind of lift at present, it can be with the machinery of patient by lifting tables, as shown in Figure 5, one is the mobile seat 50 of  shape, be fixed with the column 51 of a tiltedly upright angle at its blind end, column 51 tops articulate the suspension rod 52 that a side-looking is the ∧ shape, suspension rod 52 ends are movably equipped with the clothing suspension bracket 53 of a ∧ shape, in column 51 with on the suspension rod 52, be respectively equipped with Connection Block to be connected cylinder pressure 55, make cylinder axle 551 ends be articulated in suspension rod 52 bottom surfaces, a Pig 54 is then hung at two ends under the clothing suspension bracket 53, and human body just is placed in the Pig 54, when operation cylinder pressure 55, make cylinder axle 551 up push away when stretching suspension rod 52, clothing suspension bracket 53 just drives Pig 54, and human body rises thereupon, the action of having embraced down on nurse or caretaker have just exempted armful.

Though this kind shift unit has the convenience of its breakthrough, but still having partly, defective remains to be improved, if in operation, supply the power source generation problem of cylinder pressure 55 owing to shift unit, or cylinder pressure 55 and cylinder axle 551 one of them break down, so that when cylinder pressure 55 loses the ability of telescoping cylinder axle 551, patient will be suspended in the air or place improper positions such as ground, must mobilize the personnel more than 2 that the patient is removed to the appropriate location, and before the personnel of calling arrived, the patient may rest on out of position for a few hours; Be with how under this situation, also can promptly carry out lifting action, on armarium, need really to be studied again.

The purpose of this utility model is to provide a kind of manual lifting mechanism of patient shifting device, when the power source parts of patient shifting device break down and can't move, can do to be badly in need of to use by this manual lifting mechanism, can keep lifting and translocating, reach more definite, intimate, thorough medical care auxiliaring effect as normality.
