Description

A kind of special nursing bed that lower limb plate fold mechanism is installed

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of lower limb plate fold mechanism special nursing bed light to adapt to, critically ill patient carries out defecation under the sitting posture state that is equipped with.

Background technology

As everyone knows; Sick bed is that the modal a kind of patients of hospital is had a rest, the equipment of treatment usefulness, and the common sick bed that has toilet can only carry out the up-down of limited angle to the head of a bed at present; And to crooked sagging, very inconvenient can't be as bench time of patient's lower limb.Need patient to treat or defecation in some cases with sitting posture; And let the patient of own unable support accomplish very difficulty of this point; Therefore the urgent need design is a kind of can make patient supply to use with the sick bed that the sitting posture state carries out defecation or treatment, to demonstrate fully the characteristics of medical facilities hommization.

The utility model content

Goal of the invention: in order to overcome the deficiency that exists in the prior art, this utility model provides a kind of lower limb plate fold mechanism special nursing bed light to adapt to, critically ill patient carries out defecation under the sitting posture state that is equipped with.

Technical scheme: for solving the problems of the technologies described above, the technical scheme that this utility model adopts is:

A kind of special nursing bed that lower limb plate fold mechanism is installed; Comprise a body bracing frame, be fixed on a buttocks bed surface of body bracing frame upside, be installed in thigh bed surface and shank bed surface, the lower limb plate fold mechanism in bed body bracing frame outside; Said thigh bed surface is hinged in the A axle with bed body bracing frame, and said shank bed surface and thigh bed surface are hinged in the B axle; When lying status, buttocks bed surface, thigh bed surface and shank bed surface are positioned on the same plane, and lower limb bed surface and shank bed surface support through lower limb plate fold mechanism; When sitting upright state, buttocks bed surface, thigh bed surface and shank bed surface constitute be convenient to sit upright Z-shaped.

Compare with existing special nursing bed, this utility model is with the separately design of buttocks berth, thigh bed surface and shank bed surface, rather than the design all-in-one-piece; In the ordinary course of things, through the support of lower limb plate fold mechanism, buttocks berth, thigh bed surface and shank bed surface are placed in the same plane, its use is consistent with existing special nursing bed; When having special needs to make patient be positioned at sitting posture, the support of cancellation lower limb plate foldable structure, can form be convenient to sit upright Z-shaped.

Below thigh bed surface or shank bed surface, can weld a horizontal braces; When this nursing bed was positioned at lying status, horizontal braces supported shank bed surface or thigh bed surface, can improve the weight capacity of nursing bed; When nursing bed is positioned at the sitting posture state, can not influence its action simultaneously yet.

Said lower limb plate fold mechanism comprises auxiliary extension spring of horizontal braces, upper support bar, lower support bar, the steel wire rope that rises and falls, return and the pulley that thigh bed surface and shank bed surface is carried out horizontal support; A said end of going up steady arm and lower support bar is hinged in the C axle; The other end of upper support bar and thigh bed surface are hinged in the E axle, and the other end of lower support bar is hinged in the D axle with bed body bracing frame; The fixed axis of said pulley and thigh bed surface are fixed; Said steel wire rope one end that rises and falls is fixed on the upper support bar, and the other end is fixed on the shank bed surface after passing pulley; Auxiliary extension spring one end of said return is installed on the C axle, and the other end is installed on the B axle.

Adopt the nursing bed of above-mentioned lower limb plate fold mechanism, when nursing bed is handled lying status, the steel wire rope that rises and falls tension upper support bar; Make upper support bar and lower support bar be in tensioning state; The thigh bed surface is formed support, and owing to the effect of horizontal braces, formation is supported to the shank bed surface simultaneously; Return secondary spring tension C axle and B axle; When needs change to sitting posture with nursing bed, upwards lift the shank bed surface, because pulley drives rise and fall steel wire rope pulling upper support bar and lower support bar, upper support bar and lower support bar are moved in bed, finally make nursing bed displacement sitting posture; When needs revert to lying status with nursing bed, still, reset through the auxiliary extension spring pulling of rise and fall steel wire rope and return upper support bar through lifting the shank bed surface; Last steady arm and lower support bar can be hinged through balancing weight, and like this when resetting, upper support bar and lower support bar can close up rapidly and be in line, and upper support bar and lower support bar closing up be in line after, its continuation moved limits; The auxiliary extension spring of return can guarantee nursing bed balance of movement when resetting.

On the shank bed surface, the tailstock guardrail can be installed.

Beneficial effect: the special nursing bed that lower limb plate foldable structure is installed that this utility model provides, simple in structure, can help light, critically ill patient to become sitting posture from lying posture, convenient nursing and treatment.
