Description

Walking multifunctional nursing bed

technical field

The invention relates to the field of medical equipment, in particular to a walking multifunctional nursing bed.

Background technique

At present, the general beds where patients live in hospitals lack many functions required by patients. For example, patients who have just undergone surgery cannot perform large-scale body movements, let alone go to the bathroom to defecate. Therefore, special beds must be provided. The staff will take care of the patient's diet, turn over and defecate, etc. For families that are not very wealthy, they usually take turns to take care of the whole family, but everyone has their own things to do. If too much energy is spent on taking care of patients, not only other things will not be done well, but even their own health will be damaged. It is also unbearable; for those wealthy families, they may be willing to spend some money to hire someone to take care of their sick family members, but it will be a big expense after a long time. In addition, when some disabled patients need to go outside to breathe fresh air, they must be equipped with a wheelchair, so that the bed and wheelchair will occupy a large area of the hospital, which is not conducive to the treatment of patients with other diseases.

Although there are also some multifunctional nursing beds in China that can help patients to tilt the head of the bed, and are equipped with functions such as nurse call function, entertainment function, and liquid crystal display, but the price is very expensive, which is not affordable for ordinary patients. started. This shows that the defective of present nursing bed is: either function is not complete, can't reach and reduce the labor intensity of nursing staff;

Contents of the invention

The technical problem to be solved by the present invention is to provide a walking multifunctional nursing bed, so as to reduce the nursing cost, reduce the labor intensity of the nursing staff and the burden of the patient, and contribute to the rehabilitation of the patient.

The present invention solves its technical problem and adopts the following technical solutions: it is made up of a nursing bed, a wheelchair and an electric mechanism; the bed frame of the nursing bed is U-shaped; Control the rollover of the lifting frame and bracket hinged with the bed frame; when used as a nursing bed, the wheelchair is located in the middle of the U-shaped gap of the bed frame. Turn sideways on the support, the back of the wheelchair is turned back on the lifting frame and together with the raised wheelchair seat board forms a part of the nursing bed board; under the reverse action of the electric mechanism, the above-mentioned wheelchair components are reset, and the wheelchair can be disengaged at this time The bed frame restores the function of the wheelchair.

The bedstead 1 of the nursing bed is U-shaped. The electric mechanism includes a motor 11 and a transmission mechanism driven by it, which controls the lifting of the wheelchair, and controls the rollover of the elevating frame 8 and the support 17 hinged with the bed frame; when used as a nursing bed, the wheelchair is positioned at the U of the bed frame In the middle of the shaped gap, at this moment, the large and small wheels of the wheelchair are in the landing and off-the-ground states respectively, the side armrest 4 of the wheelchair is turned over on the support 17, and the backrest 26 of the wheelchair is turned over on the lifting frame 8 and is connected with the raised wheelchair seat plate. Together they constitute a part of the nursing bed board; under the reverse action of the electric mechanism, the parts of the above-mentioned wheelchair are reset, and now the wheelchair can break away from the bed frame to restore the function of the wheelchair.

See Fig. 2, Fig. 3 and Fig. 4: the above-mentioned transmission mechanism is provided with four upright ejector rods arranged in a triangle, each ejector rod is composed of a transmission shaft 25, an electromagnetic clutch 24 and a screw rod connected in sequence, and the bottom of the transmission shaft is equipped with Bearing block 13 and the belt pulley connected thereto, nut 22 is housed on the screw mandrel body; Among the four push rods, a push rod 14 driving the wheelchair seat plate is located at the top of the triangle, and its pulley passes through a belt and motor 11 respectively. Belt pulley, the belt pulley of the push rod 15 that is positioned at the drive lifting frame of triangle middle part links to each other, and push rod 15 links to each other with the belt pulley of the push rod 16 of two drive brackets 17 that are positioned at the rear end of triangle again by a belt. Belt 12 can select A type belt.

Since the transmission accuracy is generally not very high, the measures that can be taken are: first calculate the lift of each screw rod separately, and then select the appropriate pulley and transmission ratio accordingly.

The mutual conversion process between the bed and the wheelchair is as follows: the wheelchair itself is embedded in the middle of the bed. When it is necessary to turn into a wheelchair and go out, first activate the recline button on the head of the bed to raise the head of the bed to a suitable position, and then press the button on the wheelchair. The base descends the button, and after the base stops, people manually pull up the armrests on both sides of the wheelchair embedded in the bed, and connect the backrest 26 and the side armrests 4 through the hook 28 . Finally, the three boards at the end of the bed are picked up and put aside, so that the wheelchair can go out. When the patient wants to return to the bed after outdoor activities, the wheelchair should be moved back into the middle of the bed, and then press the up button to make the base of the wheelchair rise to be level with the bed, and then pull the hook between the backrest and the armrest, Let the backrest fall to the head of the bed, the armrests on both sides are embedded in the bed, and finally press the button on the head of the bed to make the bed flat.

See Fig. 5 and Fig. 6: the above-mentioned backrest 26 can be connected with the side armrests 4 on both sides of the wheelchair through two hooks 28 hinged thereto, so that it is in an upright or inclined state. When the hook 28 is disengaged from the side armrest 4, the hook is received in the opening groove 27 of the cart armrest 32.

Referring to Fig. 1, Fig. 5, Fig. 7: small wheel 5 is contained in the front end of trapezoidal support 29, and the round pipe 33 of this support rear end is movably sleeved with the rod body of cart handrail 32 and connects. The axle 30 of big wheel links to each other with a cylindrical slide block 31 by screw thread, and this cylindrical slide block slides up and down along the notch 34 of circular tube 33, has just realized the lifting of little wheel.

A bedpan convenient for taking out can be installed below the seat plate of the wheelchair 3 . The bedpan can facilitate the defecation and defecation of patients, and the bedpan is covered with a plastic bag to facilitate the treatment of feces. When the patient needs convenience, he only needs to remove the top layer of mattress of the wheelchair.

Bed frame 1 of the present invention, its structure as shown in Figure 1, Figure 2 and Figure 3: four bed legs can adopt square steel or round steel to make. Below the tail of the bed, available thin flat irons 20 are welded together at the bottom of the two side supports of the bed frame, so that the U-shaped bed frame is stable without affecting the access of the wheelchair. The side door 9 of beautification function is housed in the both sides support of bedstead. Be provided with the headboard 7 resting on the bed frame near the backrest 2 of the bed. On the inner side of the bed frame, angle steels 21 connected thereto are installed on both sides, so that the footboard 10 rests on its bottom edge; near the headboard 7 of these two angle steels 21, vertically connected with both sides of the inner side of the bed frame are installed. The angle steel 21 (seeing Fig. 3) so that lifting frame 8 rests on its bottom edge.

A switch box (not shown) is installed on the bedside of the nursing bed, and the buttons it is provided with include: buttons for controlling music playback and desk lamp switch, buttons for controlling lifting frame 8 and support 17 rollover, and controlling columnar slider 31 to slide up and down The limit switch 23. Here, to realize the pitching of the head of the bed, the rollover of both sides of the bed, and which function in the rising and falling of the wheelchair base, you can press which button on the head of the bed to make the motor 11 drive the transmission mechanism to realize this function.

Referring to Fig. 2: two brackets 17, the inner sides of which are hinged with the inner side of the bed frame, and a conduit 18 and a sliding block 19 which is slidably sleeved thereto are respectively installed on the back side near the headboard 7, the sliding block 19 Link to each other with the nut 22 on the screw mandrel of push rod 16 by strut. Thus, when the nut 22 is raised or lowered, the pole drives the slide block 19 to move accordingly, and the support 17 is driven to turn up or turn down on the bed frame. When the support 17 was turned up, the side armrest 4 could be promoted to turn up.

Additional functions of the present invention are as: listening to music, illuminating, only need to click the corresponding button on the head of the bed. The last thing that should be proposed is to put a board on the guardrail at the end of the bed, which can also be used for office work and meals.

The working process of the present invention is illustrated below in conjunction with accompanying drawing:

Referring to Fig. 1: the trapezoidal support 29 that connects small wheel 5 can lift within a certain range. When the push rod 14 jacked up the trapezoidal support 29, the large wheels of the wheelchair could remain close to the ground. When the seat board of the wheelchair was flush with the bed surface, the patient put down the hook 28 as shown in Figure 5, so that the backrest 26 of the wheelchair and the side armrest 4 of the wheelchair can be embedded in the bed frame 1 smoothly. When the patient uses a wheelchair, the electric mechanism shown in Figure 3 and Figure 4 can be used to lift the backrest and the side armrest, and the patient can manually complete the connection of the mechanism shown in Figure 6, and then control the push rod 14 to push the wheelchair seat plate slowly. Lowered, the wheelchair can be separated from the bed body smoothly like this, and the patient has only completed a small part of the workload within his power.

See Fig. 5: when the wheelchair is about to go out, the wheelchair backrest 26 and the side armrests 4 are raised, and when they reach a suitable position, the hook 28 is lowered to hook the side armrests, so that the side armrests and the backrest are fixed, and the wheelchair is assembled .

Referring to Fig. 5: the cylindrical slide block 31 drives the small wheels 5 to slide up and down in the tubular structure of the trapezoidal support 29, to cooperate with the combination of the bed and the wheelchair. In addition, the cylindrical slider 31 limits the four degrees of freedom of the big wheel except for the rotation and movement around the round tube 33 of the trapezoidal bracket, and the freedom around the round tube is controlled by the sleeve that is threaded with the shaft 30 of the big wheel Restricted, so the ladder bracket can only slide up and down.

Referring to Fig. 3 and Fig. 4: the motor 11 drives the pulley through the belt 12, so that the drive shafts 25 of the push rods 14, 15 and 16 are rotated. When the electromagnetic clutch 24 was controlled to the locked state by the travel switch 23, the transmission shaft would drive the screw mandrel connected with it to rotate together, so that the nut 22 on the screw mandrel moved up and down. Drawing) then drives the up-and-down motion of the wheelchair seat plate or the rollover motion of lifting frame 8, support 17. When the electromagnetic clutch 24 is controlled to the open state by the travel switch, the screw mandrel and the transmission shaft are in a separated state, the screw mandrel no longer rotates, and the nut 22 no longer moves up and down. By controlling the clockwise or counterclockwise rotation of the motor, it is possible to control whether the nut moves upwards or downwards, thereby controlling the movement of the wheelchair seat plate, lifting frame 8, and support 17.
