Abstract

The invention relates to a multi-frame bed surface friction reduction structure for a patient transfer bed, which belongs to the technical field of auxiliary medical equipment and consists of an upper bed panel (1), a lower bed panel (1), a front guide strip (3), a bed frame (4), bed surface cloth (5), bearing strips (6), a cloth rolling roller (7), a deviation prevention weir (8) and a cloth pressing roller (9), wherein the upper bed panel and the lower bed panel are divided into a plurality of gaps greater than the thickness of the bed surface cloth by a plurality of transverse bearing strips, the bed surface cloth is also correspondingly divided into a plurality of cloth frames matched with the gaps, all the cloth frames are synchronously rolled through being driven by the cloth rolling roller, the front guide strip is arranged at the front end of the lower bed panel, and the lower bed panel is ensured to be smoothly pushed on the bed surface. The upper bed panel is provided with the surface with low friction coefficient, and the frictional resistance between the bed surface cloth and the upper bed panel can be reduced. Compared with the existing product, the multi-frame bed surface friction reduction structure has the advantages that the frictional resistance can be reduced by two thirds, and the service life of the bed surface cloth and the service life of the cloth rolling roller are prolonged. The goal of energy saving can be reached through reducing the power of a motor of the cloth rolling roller.

Description

A kind of patient meets and sends off several bed surface antifriction structures of bed

Affiliated technical field

The present invention relates to a kind of patient and meet and send off several bed surface antifriction structures of bed, belong to the medical auxiliary equipment technical field.

Background technology

At present, the electronic patient of known employing bed surface cloth scroll mode meets and sends off bed has two kinds of structures.A kind of is not have bed panel down, and the sheet that the following bed surface cloth of last bed panel is with patient uses directly contacts, and bed surface cloth is owing to load has produced frictional resistance and the frictional resistance between bed surface cloth and sheet between bed surface cloth and last bed panel upper and lower surfaces at this moment.Frictional resistance is quite big, promotes sheet sometimes.Therefore, the power of motor of promotion bed surface is bigger.Another kind has increased time bed panel, makes bed surface cloth directly not contact with sheet, has reduced certain frictional force, and has reduced the probability that promotes sheet.But still exist to go up the frictional force of bed panel upper and lower surfaces and bed surface cloth and the frictional force between panel upper surface and bed surface cloth of leaving the bed, total frictional resistance is still very big.The power of motor that promotes bed surface is more very nearly the same than first kind.The increase of frictional resistance can cause the increase of pushing motor power on the one hand, is unfavorable for energy-conservation; Big on the other hand frictional resistance can obviously reduce the life-span of bed surface cloth and cloth beam.Can make electronic patient meet and send off the reliability decrease of bed, use cost increases.

Summary of the invention

The objective of the invention is to,, a kind of antifriction structure of several bed surface structures is provided in order to reduce the frictional resistance that electronic patient meets and sends off bed effectively.

A kind of patient meets and sends off several bed surface antifriction structures of bed, by last bed panel, and following bed panel, preceding sliver, bedstead, bed surface cloth, support strip, cloth beam, anti-inclined to one side weir and compress roller are formed.Last bed panel, following bed panel and support strip form the main body of bed surface jointly, and some support strip framves make and form a plurality of independently spaces between the bunk bed panel between last bed panel and following bed panel.This spatial height is greater than the thickness of bed surface cloth.Bed surface cloth is around on cloth beam and the bed surface main body, is exactly to make bed surface cloth be around in bed panel in saying specifically, and bed surface cloth is through the space between the bunk bed panel.Under volume face cloth rewinder roll drove, bed surface cloth can be initiatively around last bed panel motion.

Above-mentioned bed surface cloth can only form a plurality of cloth width of cloth because the existence of support strip can not form the complete cloth width of cloth, and structurally these a plurality of cloth width of cloth are independently, no direct correlation.The compress roller that will lean on cloth beam that is synchronized with the movement of a plurality of cloth width of cloth provides jointly.Under non-slip situation, said several bed surface cloth are with synchronous scrolling, like the motion morphology of same view picture bed surface cloth.

Can not squint each other between above-mentioned several bed surface cloth, will cause the overlapping pile-up of the cloth width of cloth, be unfavorable for forming good cloth shape as squinting.Therefore, anti-inclined to one side weir is being installed, with adjustment cloth shape on the cloth beam between each width of cloth bed surface cloth.

Above-mentioned down bed panel stretch out the edge that front end is a thin plate, shape such as blade possibly scrape medicated clothing, sheet as not adding processing, and advance resistance is increased suddenly.What is more, also might give patient, and medicated clothing and sheet cause damage.For fear of above-mentioned condition occurring, infra bed panel front end of the present invention has installed preceding sliver additional, and its effect is to have reduced time bed panel to promote medicated clothing and sheet, and injures patient's probability.Because preceding sliver be the shape of slyness, its progressive resistance greatly reduces, and helps under the health that bed panel successfully is inserted into patient.

Description of drawings

Fig. 1 bed panel of the present invention, bed surface cloth layout drawing (overlooking).

Fig. 2 A-A sectional view.

Fig. 3 B-B sectional view.

Token name is claimed among the figure: 1. go up bed panel, 2. descend bed panel, 3. before sliver, 4. bedstead, 5. bed surface cloth, 6. support strip, 7. cloth beam, 8. anti-inclined to one side weir, 9. compress roller.

The specific embodiment

Among Fig. 1, visible bed surface cloth is divided into several.Between each width of cloth bed surface cloth, an outstanding anti-inclined to one side weir is arranged at the cloth beam place, it can together rotate with cloth beam, thus it preferably circle block ring.Should anti-inclined to one side weir be isolated by each cloth width of cloth, prevent to occur between each cloth width of cloth the situation of skew.

Fig. 2 is the A-A cross section signal of Fig. 1.It is thus clear that the bed surface of being made up of last bed panel, following bed panel and bed surface cloth is supported by bedstead, and on bedstead, slide or roll.Bed surface cloth is divided into several, and the gap of passing the bunk bed panel can be around last bed panel scrolling.The gap of said bunk bed panel is formed by the multi-support bar.The effect of support strip is the rigidity that has increased last bed panel, makes that the bed surface cloth at bunk bed panel gap place can not produce frictional resistance.Through this layout, compare with existing like product, can reduce friction resistance more than 1/3rd.

Fig. 3 is the signal of B-B cross section.It is thus clear that bed surface cloth is around the layout form of last bed panel.Cloth beam provides the power of batching, and the compress roller makes bed surface cloth and cloth beam produce the frictional force that enough drives bed surface cloth scrolling.Also visible from this figure, bed surface is placed on the bedstead, and can move at bedstead.

Claims

1. a patient meets and sends off several bed surface antifriction structures of bed, belongs to the medical auxiliary equipment technical field.By last bed panel (1), following bed panel (2), preceding sliver (3), bedstead (4), bed surface cloth (5), support strip (6), cloth beam (7), anti-inclined to one side weir (8) and compress roller (9) are formed.The bed surface cloth (5) of tubular drives bed surface cloth (5) jointly by cloth beam (7) and compress roller (9) and rotates on last bed panel (1) and cloth beam (7), and it can be rotated around last bed panel (1).
