Description

Wheelchair type turning bed

1. Technical field

The invention belongs to the technical field of medical care equipment, and discloses a wheelchair-type bed for turning over and receiving stool. the

2. Background technology

In recent years, there have been more and more rare medical turning beds. Among them, the Bonen Turning Nursing Bed (201120235204.5) and the C02 Multifunctional Nursing Bed (200820077738.8) are turning beds with high cost performance and strong practicability in the current low-to-middle market. The former The bed board adopts a three-piece type, and the left and right sides can be turned over by arching the middle board and any hinged side board upwards. The latter bed board adopts a two-piece type, which is V-shaped. They all have the function of turning over, and also have a bedpan, but they are all intermittent turning. If they can turn back and forth at a low speed, it will be more caring. The key is that the incontinence problem of paralyzed patients in the middle of the night cannot be solved. It is possible to design fences that are suitable for different patient shapes and deal with the problem of the patient's body sliding down after turning over. It is inevitable that when the patient is not aligned with the defecation mouth during the turning process, the urine and feces will be drowned. The bedpan is also like a fake, because these beds are extremely difficult to deal with the quilt in the design, it is difficult to restore the original shape when it is turned over and returned, and the existence of the gap also makes the quilt unable to keep warm. If it is not supported, it will easily cause injury if it is repeated for a long time. The purpose of the present invention is to use the most economical and easiest method to realize multi-function, and accurately solve the problem of connecting toilet and defecation in any state and the above-mentioned defects. the

3. Contents of the invention

A wheelchair-type turn-over and toilet bed is mainly composed of four parts: a tripod, a rotatable bed frame, a movable bed board and a rotating toilet frame. Its pioneering and innovative invention mainly has five points:

1. Accurately align the defecating mouth, and ensure that the body does not slide down when turning over: the entire bed frame is designed to turn over smoothly, at a low speed, and cyclically, and the railings are canceled, and the side panels are responsible. Since the side panels are narrow, the design block is movable When turned sideways, it can be moved into the recessed hook-shaped frame board to accommodate wider arms, and when it is laid flat or seated, it is flush with the bed board. During the rollover, the axis center and the semi-warp principle of the same circle are used, and the arc-shaped guide plate on the foldable side plate and the positioning wheel on the stand are used to ensure that the bed is kept equal no matter what angle the bed is turned over. The touch wheel and the touch plate under the side plate push the telescopic plate on the side plate to the patient’s body, and lock the body size of various patients, and add some dimensions at the end of the arc guide plate to offset the human muscles behind the side The lower pressure thickness can effectively prevent sliding. the

2. The hospital bed shrinks into a wheelchair: mainly through the design of the hook-shaped frame panels, movable panels, seat panel side panel frames and leg panel side panel frames in the left and right side panels, especially the groove-type two-way folding (4) structure and H-shaped The ingenious design of the folding (10) structure is simple and reasonable, and easily solves the relatively difficult two-way folding problem of the side panels. In addition, there is an automatic control of the positioning struts between the leg panels and the foot panels. It is easy to switch and fix the two angles required by wheelchairs and hospital beds. If you encounter an obese patient, you don’t need to fold up the side panels to lie down. The spaciousness is more suitable for rest. At this time, you only need to put down the legs and feet. It's a recliner. the

3. Design a rotary toilet frame: the top and side of the rotary toilet frame are respectively a toilet and a toilet cover, which are placed on the moving frame through the axis wheel, and because the edge of the moving frame (44) top It is an inverted splayed guide edge with a set of symmetrical hypotenuses. Pushing the moving frame can realize the rising or falling of the rotating toilet frame. The toilet is very wide, for the whole buttocks to sit on the toilet, which has completely changed the traditional method of digging a hole in the seat cushion. There are bumper plates on both sides of the moving frame. When the moving frame moves, the rotating toilet can be moved simultaneously Box push to flip. the

4. Simple and effective positioning strut design: its structure is composed of a Y-shaped rod, a short swing rod and a strut. At the same time, a short swing rod is connected in series, and the lower end is provided with a retaining tube. The pulley at one end of the Ya tip is placed in the chute of the footboard, the other end of the short swing rod is pinned to the long stay rod, and the other end of the long stay rod is pinned to the shaft hole. The pin is connected to an inward axis hole of the semicircular guide plate below the bed frame. the

5. Realize the stable and low-speed circulation of the entire bed frame: the two semicircular guide plates under the bed frame are placed on the four pulleys of the tripod, and through the motor and the reduction gear set, the hourly rate required by the nursing specification is realized. The number of turns can also be turned over at high speed. When turning left, because the arc-shaped guide plate of the left side board hits the left positioning wheel, the left side board has turned to 90 degrees at this time, but the right side board has not touched the right positioning wheel, and is still in line with the bed board, so At this time, the bed board is L-shaped from the cross section; when the right side is turned over, because the arc guide plate of the right side board touches the right positioning wheel, the right side board has turned to 90 degrees at this time, while the left side board has not touched. The left positioning wheel is still in a straight line with the bed board, so the bed board is also L-shaped at this time. If the side panels on both sides can be turned up 90 degrees simultaneously in order to be suitable for plant patients, at this moment, there is no need to touch the positioning wheels, and the bed is equally turned over smoothly. the

Said movable bed board is the general name of middle bed board and side board, and wherein side board it has included hook-shaped frame board (16), movable board (15), pillow expansion board (65), seat board side board frame (8) , seat plate expansion plate (1), leg plate side plate frame (12), leg plate expansion plate (11). The expansion plate refers to the panel attached to the frame plate. The scissors lever is used to realize the expansion and contraction between the side plate frame and the expansion plate. On the positioning wheels (18, 24), keep the bed surface flat, but when the bed frame (63) turns over, it will be restricted by one of the positioning wheels (18, 24), and the side panels will not move down. The bed board continues to turn downwards, and the side board and the bed board are gradually closed, that is, the side board is turned toward the patient's body. Since the semi-longitude of the same circle is equal, when the inner angle reaches 90 degrees, the side board does not move, and the bed board can continue to turn over. Vice versa, at this time, the upper side board is still in line with the bed board because it has not touched the positioning wheel, and the lower side board has been formed at 90 degrees. Add some dimensions to the end to offset the downward pressure thickness of the human muscles behind the side, so as to effectively prevent sliding. At this time, the inner angle of L is actually less than 90 degrees. the

Five , embodiment

The wheelchair-type bed for turning over and receiving stool is mainly composed of four parts, a foot frame, a rotatable bed frame, a movable bed board and a rotating toilet frame, and two semicircular guide plates (17 ), placed on the four pulleys (48) of the tripod (26), the semicircular guide plate (17) at the back is provided with an arc-shaped rack, through the motor shaft gear (50) and the reduction gear (49) to realize half The circular guide plate (17) and the low-speed circulation of the bed frame (63) turn over; the side plate realizes the horizontal and vertical two-way turning through the groove-type two-way turning (4) mechanism and the H-shaped two-way turning (10) mechanism ;Fix the foot plate (13) and leg plate (14) at two different angles by positioning the struts (21), thereby simply and quickly realizing role switching; use the upper plate of the moving frame (44) to move along an inverted figure-of-eight guide edge , the rotating toilet frame (39) is raised and lowered through the axis wheel (41), thereby bypassing the thickness of the mattress that will collide during the rotation, and at the same time being pushed by the moving frame (44) bump plate (64), The rotary toilet frame (39) is forced to turn over, and the easy conversion of the toilet (3) and the toilet cover (2) is realized. the

Traditional sick beds all have railings, and the present invention cancels the railings and replaces them with side panels. The bed panels and the side panels should be used as a rotating body. Through the principle of equality, draw a circle on the outer edge of the side panel folded into 90 degrees, and its semi-longitude is equal to the distance from the axis center to the positioning wheels (18, 24), so no matter how much the bed frame is folded over, the distance between the bed panel and the side panel Internal angle all can be constant, and the outer edge on side plate is arc guide plate (23). When the bed board is turned over, only the left and right arc-shaped guide plates (23) are hindered by the positioning wheels, and the side plates are turned inward, and the inner angle gradually becomes smaller as the bed frame (63) is turned over to the side. . When it is turned to 90 degrees, it will remain unchanged. Since the other upper side board is not restricted by the positioning wheel, it is still in a straight line with the bed board, so the current bed board is L-shaped as a whole, which is very convenient for patients to sleep on their side . When laying flat, the side panels are at the same level as the bed surface, and the touch plate (32) at the lower end of the expansion plate (1) of the rear seat plate is moved forward due to the push of the touch wheel (31) on the screw rod. , stop when it is fixed at a position close to the patient's body, and return to the same level with the bed surface when it is laid flat. In particular, some dimensions are intentionally added to the tail end of the arc-shaped guide plate (23) to counteract the impact of the human body. The thickness of the downward pressure of the muscles behind the sideways can effectively prevent sliding. the
