Description

Bed capable of nursing and supporting patient

Affiliated technical field

This utility model belongs to automatic care bed and electromechanical integration technology.

Background technology

The old man of long-term bed, patient easily suffer from decubital ulcer, and the normal person did not stand up above 1-2 hour, and the danger of suffering from decubital ulcer is just arranged.Regularly standing up the change patient posture, can prevent that the body part pressurized is of a specified duration excessively, is the effective means that prevents that decubital ulcer from taking place.

Prior art, for example Chinese patent application 01234038.3＜bed capable of nursing and supporting patient 〉, bed board before, during and after being hinged with, with the framework of vertical forward and backward backup plate is clipped between the forward and backward end plate; Between corresponding end, backup plate rotating shaft is arranged; Forward and backward backup plate tape frame rotates in positive and negative 90 degree and pauses; In the chute of framework both sides, respectively have one can ascending, descending side plate, the driven by motor friction pulley that rotates synchronously on the framework is at two side drive side plates, framework and side sheet room are equipped with clutch, and be that auxiliary rope is arranged, in, the back bed board each with a panel turnover mechanism change angle that is sleeved on the frame; Be narrower than the back side at the nearly two side places of preceding bed board free end of two track spaces, each fixes a cover Tong, in have can controlled flexible round pin, in round pin is withdrawn into cover Tong, change on the bed board during panel turnover mechanism makes and the external crucible front edge of board is raised through stop, when round pin integral body exceeds two track formed planes, round pin stretches out, and the external crucible front edge of board puts down, and it is moving that round pin just can rest on the track sliding (rolling), (at this moment, round pin also can further extend in the hole of track side surfaces), in the time of in round pin is withdrawn into cover Tong, middle bed board changes down, bed board forwards under two tracks before making, up to perpendicular to the ground; Between chamber pot and middle bed board relative motion is arranged.

Above-mentioned bed capable of nursing and supporting patient, do not mention should respective change guardrail; Round pin needs 3 states, and framework and side sheet room are equipped with clutch, and is to have auxiliary rope to transmit side plate power, and more complicated cannot say for sure to demonstrate,prove the steady lifting of framework of unbalance stress; Inconvenience changes back bed board angle at any time, has relative motion not make full use of between chamber pot and middle bed board.

The utility model content

The purpose of this utility model is that a kind of bed capable of nursing and supporting patient that has improved will be provided, it can be more reliably with on the backup plate before and after stressed being delivered to of side plate institute, framework is steadily moved and self-locking and utilize chamber pot with middle bed board between relative motion change in the angle of bed board, bed board angle panel turnover mechanism is contained on the framework after changing; Can also serve as the clutch of preceding bed board and framework with the flexible round pin of 2 states and increase corresponding upper and lower mobile guardrail.The technical scheme that its technical problem that solves this utility model adopts is:

After stock stretches in the side plate one side slotted hole and traverses side plate, in side plate opposite side slotted hole, stretch out, stock two ends are separately fixed on the backup plate of front and back, stock and side sheet room link with the scissor lift platform of driving device lifting, adopt hollow stock, wherein place electric wire and fluid line, at the fixing respectively slide block that can in the backup plate slotted hole of front and back, slide of side plate two sides; Utilize the relative motion of bed board and pail closet to make chamber pot push middle bed board, the external crucible front edge of board be placed on install additional on the limited slide rail in orbit and slide, in the change before angle between bed board, the clutch of bed board and framework before only serving as with the round pin of 2 states of stretching, contract; Changing back bed board angle panel turnover mechanism is contained on the framework; The driver scissor lift platform that stretches makes that guard rail rod is upper and lower to be moved.

The beneficial effects of the utility model are:

Utilize stock, and slide block, on backup plate before and after stressed being delivered to of side plate institute, place electric wire and fluid line in the hollow stock, more safe and reliable, it is more steady to utilize the driving device lifting scissor lift platform that is contained in the side plate that side plate is moved, it is easier to change back bed board angle, saved the panel turnover mechanism under the middle bed board, guardrail is arranged, the clutch of preceding bed board and framework is easier.
