Abstract

The utility model relates to a new style sick bed for preventing bedsore. Besides a bed frame, bed levers and a bed surface, the sick bed for preventing bedsore also has a bed body bracket which is well distributed with struts and is respectively driven by two sets of cam wheels to lift and fall. The utility model can also forms a bed support surface which is composed of points, and two sets of the points with different positions can be steadily alternated and converted. By the use of the utility model, the number that the laid-up patients are turned by sick beds can be reduced. Althouth patients lies on beds for a long time, the bedsore can be prevented from forming, which is favorable to the rehabilitation of the patients.

Description

The sick bed of prevention decubital ulcer

This utility model relates to medical hospital bed, particularly a kind of sick bed that can prevent decubital ulcer.

Its health of patient that decubital ulcer usually occurs in long-term bed contacts the position of pressurized with bed surface, its incidence rate is high, often has 1/3 to take place in first week of bed, and 2/3 took place in second week of bed.It not only brings misery to patient, causes great difficulty also for nursing staff's nursery work.Yet, still there be not the ideal method and suitable sick bed that prevents that decubital ulcer from taking place at present, become clinical urgency problem to be solved.

The purpose of this utility model is intended to propose the bed body that the densely covered pillar of a kind of usefulness constitutes, and the prevention decubital ulcer sick bed at the pressurized position that can change patient body at any time by the conversion and the lifting of bed surface fulcrum, to overcome weak point of the prior art.

The purpose of this utility model can realize by following proposal.

The sick bed of prevention decubital ulcer comprises forward and backward bedstead 5, bed thick stick 7 and a software pulling force bed surface 4 of both sides.Both ends at both sides bed thick stick, by axle bed 12 camshaft parallel with bedstead 11 is installed respectively, on every camshaft, fixing 4 cams 10 that shape is identical, wherein the protruding peak near two cams in two cams at center and the outside differs 180 °, 4 cams and 4 cams in the outer part by the center on two camshafts constitute two cam set supporting surfaces respectively.On the supporting surface of each cam set, each is supporting a support 1 that is fixed with a plurality of pillars 2, and the pillar on two supports vertically for alternately.

Below in conjunction with embodiment and accompanying drawing, this utility model is described in detail.

Fig. 1 sick bed front view.

Fig. 2 sick bed sectional view.

Fig. 3 sick bed vertical view.

Fig. 4 pillar sketch map.

The bedstead 5 of this utility model sick bed and bed thick stick 7 are approximate with common bed.Camshaft 11 is installed on the bed thick stick, and is supported two supports 1 of conduct bed body by two cam set on the camshaft.Support has a frame 3 that can be supported on the cam set, and lateral separation, frame upper edge is fixed with many bent plates 8, is connecting a plurality of strut sleeve 15 on every bent plate, and the lower end of pillar 2 is loaded in the tube, and spring 14 is housed within it.Bent plate on two relatively independent supports constitutes a bed body alternately.

The rotation of two camshafts in the sick bed is driven by the one group of sprocket wheel 6 that is located at a side center, and its power can rotate by rocking handle 16 with hands and realize, also can connect other actuating devices and realize.

In order to keep the horizontal level of support, a support of one of two stands respectively has one group of fairlead mechanism 13 between the middle part and bed thick stick at two ends.Four guide rail mechanisms 17 are also arranged respectively at two ends between this support and another support.

Bed surface can be with material such as nylon cloths, is installed on the bedstead with carbine, and bed bodies such as pillar are covered.

Operation principle of the present utility model is: by the rotation of camshaft, making two cam set alternately drive two supports rises respectively or descends, thereby change the position of pillar contact patient body, it can change ordinary hospital bed plane contact human body, cause local skin and subcutaneous tissue ischemia to form necrosis, liquefy and fester into the situation of skin ulcer.

Structure of the present utility model can guarantee to form the steady checker of point-supported bed body, the spring in the pillar also further compensator or trimmer pressure increase comfort level, help preventing the decubital ulcer generation.Use this utility model sick bed, can significantly reduce and stand up number of times, both made long-term bed, also can prevent the formation of decubital ulcer, help patient's rehabilitation.
