The former bed plate is supported by three rotating shafts, and the left and right sides are turned up by arching the middle plate and the hinged upper side plate; the latter bed plate is made of two pieces, which is V-shaped, and one of the plates is turned by the rocker. Jacking up to achieve turning over, both have a turning function, but also a potty, but they are all a single intermittent turn-over, if you can cycle back and forth at low speed, it is not more intimate care. The key is to fail to solve the problem of incontinence in the middle of the night. The reason is that the problem of not being able to design a bar that fits the shape of different patients and to deal with the body's decline after turning over is inevitable when the patient is in the process of turning over. It is not allowed to gargle and cause leakage of urine and urine. At this time, although the potty is also a dummy. Since these beds are extremely difficult to handle in design, it is difficult to restore the cover when the flap is retracted. The presence of the gap also prevents the cover from being warmed, and the flap is too short, below the legs. Unsupported, long-term repeated can also cause injury. SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned drawbacks, and to solve the problem of urinating and defecating in any state in the most economical and simple manner, and to realize the most practical and versatile.

[Summary of the Invention]

A wheelchair-type body-turning bed, including a tripod, a rotatable bed frame, a bedside splice plate, and a rotating toilet seat frame, mainly has four pioneering innovative ideas:

(1) Boldly treat the patient's body as a porcelain storage, and insert it into the flipper sponge board to ensure that the body does not move in the side.

(2), changing the traditional practice of opening the toilet seat, but expanding the area of the toilet, the hole The mouth is only open on the toilet so that the urine does not flow to the edge of the pad after the rollover.

(3) Using the principle of the same circle and half equal, the outer shape of the curved guide on the side plate of the seat plate is made equal to the arc on the circle. When the positioning wheel on the bed frame is turned over, the turning angle is changed while the inner angle of the side plate is maintained at 90 degrees.

(4) In the process of becoming a wheelchair, when the backboard 7 is turned up, since the seat panel side frame 8 is erected at the hand, when the edge of the seat panel side frame 8 and the backboard 7 become smaller, it may cause a patient Injury, the technology uses a two-axis design, that is, the pin 55 moves up in the wheelchair state, and when the back plate 7 is folded up, the lower portion of the back plate is retracted to avoid injury to the patient.

Eleven invention highlights: side panel design, flex panel design and application, trough bi-folding, H-style bi-folding, rotary toilet, hook-and-loop panel, foldable hand, urinal and head Belts, quick-release struts, semi-circular guides, and covers are designed.

The wheelchair type body-turning bed according to the embodiment has the following characteristics:

1. Accurately align the sputum and ensure that the body does not slide after rolling:

The whole bed frame is designed to be smooth, low-speed, and cyclically turned over. The traditional multi-functional nursing bed has a guard rail. The present invention eliminates the railing, and replaces the side panel with the side panel, and the bed panel and the side panel as an integral rotating body. By using the principle that the virtual axis of the semicircular guide 17 is equal to the arc of the same circle, the outer edge of the side plate to be folded into 90 degrees is drawn in the design, and the half is equal to the axis to the positioning wheel 18, 24 The distance between the bed and the side plates is kept constant regardless of the degree of folding of the bed frame. The outer edge of the side plate is the curved guide plate 23. When the bed is folded, the arc is only one side. The guide plate 23 is obstructed by the lower positioning wheel, so that the side plate is naturally folded inward, and is kept unchanged after being turned to 90 degrees, and the other upper side plate is not restricted by the positioning wheel, so The bed board is also protected with a flat surface. At this time, the bed board is L-shaped as a whole, which is very convenient for the patient to sleep on the side. When the flat plate is laid flat, the side plate is flush with the bed surface, and the bottom plate 32 of the lower plate of the rear plate expansion plate 1 is automatically stopped by the movable contact wheel 31 on the screw which is measured by the original one. The desired position on the patient's body is restored to the level of the bed when laid flat. In particular, the size of the curved guide 23 is deliberately added to offset the downward pressure of the human muscle behind the side body. The thickness thus acts to effectively prevent the slip.

2. Conversion from bed to wheelchair: Mainly through the design of the hook frame 16 in the bed panel, the foldable hand panel 15, the seat panel side panel 8 and the leg panel side panel 12, especially the trough bidirectional folding 4 structure and the H bidirectional folding The clever design of the 10 structure makes it easy to solve the difficult two-way folding problem of the side panel.
