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 transfer bed bed surface cloth friction-reducing structure

Affiliated technical field

The present invention relates to a kind of patient transfer bed bed surface cloth friction-reducing structure, belong to the medical auxiliary equipment technical field.

Background technology

At present, the electric patient transfer bed of known employing bed surface cloth scroll mode has two kinds of structures.A kind of is without lower bed panel, and the sheet that the bed surface cloth of upper bed panel bottom is with patient uses directly contacts, and bed surface cloth is owing to load has produced frictional resistance between bed surface cloth and upper bed panel upper and lower surface and the frictional resistance between bed surface cloth and sheet at this moment.Frictional resistance is quite large, promotes sometimes sheet.Therefore, the power of motor of promotion bed surface is larger.Another kind has increased time bed panel, so that bed surface cloth does not directly contact with sheet, has reduced certain frictional force, and has reduced the probability that promotes sheet.But still having the frictional force of bed panel upper and lower surface 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 large.The power of motor that promotes bed surface is more very nearly the same than the first.The increase of frictional resistance can cause the increase of pushing motor power on the one hand, is unfavorable for energy-conservation; Large frictional resistance can obviously reduce the life-span of bed surface cloth and cloth beam on the other hand.Can make the reliability decrease of electric patient transfer bed, use cost increases.

Summary of the invention

The object of the invention is to, in order effectively to reduce the frictional resistance of electric patient transfer bed, provide a kind of friction-reducing structure of several bed surface structures.

A kind of patient transfer bed bed surface cloth friction-reducing structure, by upper bed panel, lower bed panel, front sliver, bedstead, bed surface cloth, support strip, cloth beam, anti-bias weir and cloth pressing roller form.Upper bed panel, lower 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 upper bed panel and lower bed panel.The height in this space 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 upper bed panel in saying specifically, and bed surface cloth is by the space between the bunk bed panel.Under volume face cloth rewinder roll drove, bed surface cloth can be initiatively around upper 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, without direct correlation.Being synchronized with the movement of a plurality of cloth width of cloth will lean on the cloth pressing roller of cloth beam jointly to provide.In the situation that non-slip, described several bed surface cloth are with synchronous scrolling, such as the motion morphology of same view picture bed surface cloth.

Can not mutually be offset between above-mentioned several bed surface cloth, will cause the overlapping pile-up of the cloth width of cloth such as skew, be unfavorable for forming good cloth shape.Therefore, between each width of cloth bed surface cloth anti-bias weir is being installed on the cloth beam, to adjust cloth shape.

Above-mentioned lower bed panel stretch out the edge that front end is thin plate, shape such as blade may scrape medicated clothing, sheet as not adding to process, and advance resistance is increased suddenly.What is more, also might give patient, medicated clothing and sheet injury.For fear of above-mentioned condition occurring, the present invention has been installed front sliver additional at lower bed panel front end, and its effect is to have reduced time bed panel to promote medicated clothing and sheet, and injures patient's probability.Because front sliver is round and smooth shape, its resistance that advances greatly reduces, and is conducive 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 claims among the figure: 1. go up bed panel, 2. descend bed panel, 3. front sliver, 4. bedstead, 5. bed surface cloth, 6. support strip, 7. cloth beam, 8. anti-bias weir, 9. cloth pressing 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-bias weir is arranged at the cloth beam place, it can together rotate with cloth beam, thus it preferably circle block ring.This anti-bias weir isolates each cloth width of cloth, prevents from occurring between each cloth width of cloth the situation of skew.

Fig. 2 is the A-A cross section signal of Fig. 1.As seen the bed surface that is comprised of upper bed panel, lower bed panel and bed surface cloth is supported by bedstead, and slides or roll at bedstead.Bed surface cloth is divided into several, and the gap of passing the bunk bed panel can be around upper bed panel scrolling.The gap of described bunk bed panel is formed by the multi-support bar.The effect of support strip is the rigidity that has increased upper bed panel, so that can not produce frictional resistance at the bed surface cloth at bunk bed panel gap place.By this layout, compare with existing like product, can capable of reducing friction resistance more than 1/3rd.

Fig. 3 is the signal of B-B cross section.As seen bed surface cloth is around the layout form of upper bed panel.Cloth beam provides the power of batching, and cloth pressing roller makes bed surface cloth and cloth beam produce the frictional force that enough drives bed surface cloth scrolling.From this figure also as seen, bed surface is placed on the bedstead, and can move at bedstead.
