Description

Ward bed for all lying positions

Affiliated technical field

The present invention relates to armarium, the sick bed that be specially adapted to burn, paralysis and coma patient uses.

Background technology

It is above the waist or/and the lifting and turning on one's side of lower limb that patient's position change does not in bed have outer.We tentatively a upper part of the body are referred to as horizontal position change to rollover or/and lifting of lower limb is referred to as vertical position change.Existing sick bed can be realized the vertical position change of patient, but is difficult to realize horizontal position change, does not more have to make the vertical position change of patient can make the sick bed of the horizontal position change of patient again.It is commonly used that tuning bed movably bed surface, the bedstead and the manual regulating device that are used to support bed surface constitute by two.During use, with two movably bed surface to drawing close together patient is clipped in the middle, patient and bed surface are turned over the purpose that turnback realizes that patient stands up together.The shortcoming of this turn-over method is: reversal rate is fast, and patient's sense of discomfort is obvious; Complicated operation, personnel selection are many, are unsuitable for family and use; Stand up angle and be difficult to select, inapplicable to paralysis and the expectoration of coma patient rollover body.Also have bed surface is designed to several bed boards, by the purpose that realizes that patient stands up of turning up of bed board.This turn-over method also has its significant disadvantages, and it is not necessarily consistent with the interfacial phase that bed board is turned up that is exactly the patient position of lying, and can not realize the laterally position change at any angle of any position of patient, has limited use.

Summary of the invention

For overcoming the various defectives of operating beds, the invention provides a kind of ward bed for all lying positions.This bed can not only make the vertical position change of patient can also make the laterally position change at any angle of any position of patient.It is comfortable that patient feels, rises and retires conveniently, stands up nature.

The present invention solves the technical scheme that its technical problem takes: bed surface uses the flexible material that can curl, and for example cloth or roller shutter all can.The both sides of bed surface are fixed on the stock at bed board both side edges place, and stock arc up moves the scrolling that has just driven bed surface, and patient stands up in the scrolling of bed surface.Bed board under the bed surface is cross-section to be divided into several sections, and the stock of bed surface and both sides thereof also is divided into several sections but still link together accordingly with bed board.Certain section bed board is turned up, and also turns up with the stock of corresponding bed surface of this section bed board and both sides thereof, can make the vertical position change of patient, and the stock that bed board puts down then corresponding bed surface and both sides thereof also puts down, and patient is flat to crouch.Stock is contained in the stock supporting plate.The two ends of stock supporting plate and two power arms are connected, and two power arms are connected with the two ends of major axis again.Major axis is under bed board.Major axis rotates and makes two power arm perks, and stock supporting plate band the stock perk, and bed surface is rolled thereupon, and patient realizes horizontal position change in the scrolling of bed surface.Power can manually also can electronicly reach full automation.Can use worm and gear, umbrella wheel, screw rod, hydraulic cylinder and motor etc. to realize above motion mode.

The invention has the beneficial effects as follows: operate simple and easyly, patient comfort is applicable to all kinds of patients of hospital, nursing house and family; Simple in structure, do not need special fabrication processes, cost is low.

The specific embodiment

In Fig. 1, Fig. 2, the bed surface that collapses (2) of ward bed for all lying positions lies low in the above patient.In Fig. 9, bed board (10) is cross-section to be divided into 4 sections.In Figure 10, bed surface that collapses (2) and stock (5) also are divided into 4 sections accordingly with bed board.The bed surface (2) that collapses is positioned on the bed board (10), and the both sides of the bed surface that collapses (2) and stock (5) are connected, and stock (5) is positioned on bed board (10) both side edges.In Fig. 7, Fig. 8, two brace summers (7) be fixed on two sections bed boards (10) below, link to each other with separately screw rod (6) respectively, this is two screw rods (6) longitudinally.There is hinged (not shown) fixing or that link to each other at the break joint place of each section bed board (10).Rotate these two screw rods (6) longitudinally, corresponding bed board (10) perk, bed surface that collapses (2) on this section bed board (10) and the perk simultaneously of stock (5) section have just formed form among Fig. 5, patient's the upper part of the body and lower limb lift, and this has just realized vertical position change of patient.Certainly, these two screw rods (6) of backward rotation, patient can also lie low.

In Fig. 1,2,5,6, ward bed for all lying positions has two major axis (4), the two ends of every major axis (4) by bearing fixing on the head board of head of a bed portion and tailstock portion.In Figure 10, the both sides of the bed surface that collapses (2) and stock (5) are connected.In Figure 11, the two ends of each stock supporting plate (3) all are connected with the upper end of power arm.In Figure 12, stock (5) is contained in the stock supporting plate (3).In Figure 14, stock supporting plate (3) is the hemicycle tubular, and its in-profile is consistent with the half cycle external shape of stock (5).In Figure 11, there are two transverse screws (6) to link to each other with two brace summers (7) respectively, the two ends of brace summer (7) link to each other with power arm respectively.Rotating a screw rod (6), just to spur two power arms (8) in the same way by brace summer (7) be that the center of circle is to this side perk of the screw rod that is rotated (6) with the central longitudinal axis of the major axis (4) of this side, stock supporting plate (3) that power arm (8) links to each other and interior stock (5) thereof just move to the top of bed arc, have just driven the scrolling of the bed surface that collapses (2).In Fig. 6, the scrolling of bed surface just can make patient's rollover of overlieing.Also just realized patient's horizontal position change.

After patient's horizontal position change is finished, will collapse bed surface (2) and stock (5) of reverse rotation transverse screw (6) to put back to original position.In Figure 11, all there is a stock holder (9) upper end of power arm (8), has four.In Figure 13, the stock holder cover plate (11) of stock holder (9) and the stock holder below of the post stock holder cover plate return spring (12) of ining succession of cranking arm between (13).The traction action of stock holder cover plate return spring (12) makes stock holder cover plate (11) cover end in stock (5), power arm (8) has limited stock (5) when falling after rise, stock (5) can not be come off, and bed surface that collapses (2) and stock (5) are homing.

In Figure 13, stock holder end wheel touch panel (15) is fixed on head of a bed portion and tailstock portion head board inside, and the same with stock holder (9) also have four.This plate has certain gradient.Collapse bed surface (2) and stock (5) moves back to the final stage of reposition from the top arc, stock holder end wheel (14) contacts on the stock holder end wheel touch panel (15), continuing to descend then, stock holder end wheel (14) upward continues to roll at stock holder end wheel touch panel (15), the stock holder crank arm (13) rotation, stock holder cover plate (11) is flared to fully gradually opens.Just lose restriction after stock holder cover plate (11) opens fully, just can rotate vertical position change of the patient of screw rod (10) realization longitudinally stock (5) end.

Screw rod has screw thread, and the tube of its outside has the female thread that is meshed with screw flight.The rotation of screw rod makes a displacement push-and-pull brace summer (7) form the power of horizontal position change and vertical position change.No matter using worm and gear, umbrella wheel, hydraulic cylinder still is motor etc., as long as can cause the rotation of major axis (4) and the perk of bed board can both realize patient's horizontal position change and vertically position change.

The both sides of cotton-padded mattress, sheet are fixed on that stock (5) is gone up or/and on the bed surface that collapses (2), change with the change of position, also can be filled between bed surface that collapses (2) and the bed board (10).
