Description

Health-care bed against bed sore

This utility model belongs to medical instruments field, accommodates in permanent bedfast patient.

At present, be used for permanent bedfast patient and use bed, it all is common home-use bed, in the hospital also not except, more senior hospital, with the bed more greatly, softer, more comfortable beds, generally the most of usefulness of hospital is ferrum bed, wood bed, the bed that the centre that the hospital that has uses can be turned up can be patient partly lie semireclining, spring mattress bed besides, also be generally to be called the soft bed of Simmons mattress, these can both play the effect that patient crouches and to sleep, but are not suitable for being unable to leave the bed the patients on long-term, and particularly elderly patients are not suitable for.Because be unable to leave the bed the patients on long-term, elderly patients particularly, blood flow is slow, patient oneself can not stand up again, long-term posture sleep, patient body by the bed surface one side is slow owing to blood flow, will give birth to decubital ulcer, giving birth to after the decubital ulcer is bad treatment, therefore, run into such patient, just need special people and help patient to stand up termly, this helps patient to stand up this work termly will expend great amount of manpower, in order to alleviate this part workload, just need a kind of blood that can prevent of design to block, keep blood circulation, prevent the bed that decubital ulcer produces, be applicable to that long-term bed does not rise, the patient that can not oneself stand up again, the patient that particularly old long-term bed does not rise.

The purpose of this utility model will design a kind of long-term bed that prevents exactly and not play the patients'blood obstruction, and is difficult for producing the bed of decubital ulcer.

The major technique that this utility model adopts is: the bed surface panel is made up of two fixed panels and polylith active face field, have vertical groove on the drop front, the two ends of every drop front are fixed with carriage release lever, a transverse slat is fixed with nut in the lower end of two carriage release levers, fix two cam bits on the two ends of transverse slat, carriage release lever is through in the riser hole that is fixed on the bedstead termination, on the carriage release lever, spring is arranged above the riser, the spring upper end, pin is arranged on the carriage release lever, below the riser, be fixed with cover on the carriage release lever, the spring ball stop is arranged in the cover, have the groove and the hole that cooperate with ball on the carriage release lever; Drop front moves down the motor that relies on bedstead bottom dress and variator, big or small drive sprocket, chain and is contained in two sprocket wheels on the power transmission shaft of bedstead termination and the power transmission shaft with support, two chains are fixed two cam bits on the cam bit compressing transverse slat accordingly drop front are moved down on two chains.

This utility model major advantage, the bed surface panel has fixed panel and drop front, have vertical groove on the drop front, the drop front alternate turns moves down, alternate turns moves up again, make patient break away from compressing discontinuously,, keep circulation to prevent the generation of decubital ulcer so patient blood is unlikely obstruction to bed surface one side surface.

Concrete structure of the present utility model is provided by following examples and accompanying drawing.

Fig. 1 is the front view that this utility model removes a frame, and Fig. 2 is the side view that Fig. 1 removes the head of a bed, and Fig. 3 is the A portion cutaway view of Fig. 1.

Describe details of the present utility model and working condition in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3.

Concrete structure of the present utility model is that bedstead (1) is arranged, bedstead is that the head of a bed, tailstock plate are arranged, and also has the bed frame and supports composition, and head of a bed bed panel (2) is fixed on the bed frame of bedstead with tailstock bed panel (3), head of a bed bed panel is wideer than tailstock bed panel, is called meaning fixed bed panel.The centre of head, tail bed panel is a polylith pulldown bed panel (4), and it is not fixed on the frame.Have vertical groove above the pulldown bed panel, that is to say that groove is vertical with polylith pulldown bed panel.The two ends of pulldown bed panel (4) have been screwed carriage release lever (5), and a transverse slat (11) is fixed with nut (12) in the lower end of carriage release lever, make pulldown bed panel (4), carriage release lever (5), and transverse slat (11) constitutes a framework.In the centre of this framework, at bedstead (1) head board, be screwed a riser (9) on the tailstock plate, porose on the riser, carriage release lever passes in the hole, can move in the hole.Go up, have above the riser (9) spring (8) at carriage release lever (5), on spring upper end, the carriage release lever pin (6) is arranged, the range of activity of spring sell exactly and riser between, the effect of spring is exactly the effect that the pulldown bed panel is supported and leaves behind.Below the riser, be fixed with cover (10) on the carriage release lever, cover is fixed on the riser with screw (24), spring ball stop (21) is arranged in the cover, have the groove and the hole that cooperate with ball in the spring ball stop on the carriage release lever, the length of groove and spring range of activity match, and the hole is a location usefulness, in other words, during Movable bed surface panel inertia, all Movable bed surface panels are remained on the horizontal plane, be exactly with the fixed bed surface panel on a horizontal plane.Simultaneously, when the weight on the pulldown bed panel was not more than personal weight, the pulldown bed panel can not move down.The Movable bed surface panel moves down and relies on motor (16) and the variator (25) that is contained in bedstead (1) bottom, size drive sprocket (17), (19), chain (18) and be contained in the head board of bedstead, power transmission shaft (20) on the tailstock plate and two sprocket wheels (13) on the power transmission shaft with support, two sprocket wheels drive two chains (14), fixing two cam bits (15) on two chains accordingly, these two cam bits are along with chain rotates.The degree of tightness of above-mentioned chain is all by tension mechanism is arranged.On transverse slat (11), be screwed last two cam bits (23) equally accordingly.When cam bit on the chain and the cam bit on the transverse slat are collided, just oppress the cam bit of transverse slat, transverse slat is fixed on the carriage release lever with nut again, therefore, the pin of carriage release lever (6) just compresses spring, carriage release lever and Movable bed surface panel are moved down reposefully, when cam is borrowed the elastic force of spring not only but also risen reposefully behind peak.The order that the rotation direction of chain (14) and carriage release lever (5) move down is to head of a bed direction by tailstock.Because the Movable bed surface panel can move down, people's the body part bed panel of just having an opportunity to break away from, just circulation of blood just is difficult for producing decubital ulcer during disengaging.Drop front (4) also can be realized by rocker cam mechanism, also can realize by the screw rod cam mechanism.Simultaneously, as long as increase by a hinge connection in the middle part of bed frame and riser (9), increase by a turning cylinder in the middle of the chain (14), same on the axle with two sprocket wheels, drive two chains, that is to say bed divide is made two joints, just can make this utility model can put down and sleep, the folded form of partly lying of partly getting up again.
