Abstract

A multifunctional full-automation care bed is formed of a chassis (1), a bed frame (2), a head board (9), a back board (7), a buttock board (6), a leg board, a foot board (3), double folded restraining sides, and a toilet fold mechanism. The back board and the buttock board are rotatable hinged boards, whose corresponding cushions are cylindrical cushions and move synchronously with the hinged boards. The back board and the buttock board are divided into three pieces longitudinally. The two pieces at the sides can fold upward, respectively. When one side board at one side is folded, the hinged boards and the rolling cushion move to the direction of the folded board, and a patient can turn over at 0 to 360 degrees. The toilet fold mechanism is installed below the leg board at the rear part of the bed frame. The middle piece of the leg board can rise driven by an electric push rod and support the legs of a patient and enable the buttocks to leave the cushion. A toilet (35) can automatically move below the buttocks of the patient as driven by the fold mechanism. The care bed is driven by a motor and eight electric push rods and is controlled by a microcontroller.

Description

Multifunctional automatic nursing bed

Technical field:

The invention belongs to the medical device industry, in particular to a rehabilitation nursing bed.

Background technique:

Most of the medical beds used in hospitals and many patients with long-term bed rests have only three functions, namely, the lifting, sitting and bending of the bed. A part of the home care bed with a toilet function is to machine a hole in the middle of the bed board, and the toilet is placed under the bed board. The mattress and the bed sheet of the bed are opened, and the patient can easily soil the mattress when it is in the urine. It is very troublesome to clean up. The existing nursing beds also have a lot of functions with turning over. The principle adopted by them is that the longitudinal division of the bed board into three middle pieces can be inclined at an angle. The problem of the method of turning over is: First, the angle of inclination cannot be too large. Too large is dangerous to the patient. Second, the patient's back cannot leave the bed and does not prevent acne, so there are few users. In reality, hemorrhoids pads are mostly used in the care of long-term bedridden patients, but hemorrhoids pads can only reduce the occurrence of blisters and cannot solve the problem fundamentally.

Summary of the invention:

Nowadays, the development of society has caused many negative problems for the human body. The weight of people has increased in patients with cardiovascular and cerebrovascular diseases. At the same time, the demand for nursing staff has also increased significantly in the elderly society. It is a labor-intensive, dirty and tired job. 70% of the work of nursing staff is to turn over the bedridden patient and handle the patient's bowel movements. From the perspective of nursing, the more times the bedridden patient turns over, the better. Turning over has two functions: one to prevent hemorrhoids, and the other to increase bowel movements to promote digestion and defecation. The multifunctional automatic nursing bed of the invention increases the function of the existing hospital bed without the presence of the nursing staff, and can automatically turn over and autonomously defecate. Its turning principle is to design the back bed and hip bed as a chain bed, and the mattress is a tubular mattress. At the same time, the two sections of the bed are longitudinally divided into three pieces, and the middle piece is fixed, and the two side plates on both sides can be folded up separately. After the bed board is folded up, the chain plate moves in the direction of the folded bed under the driving of the motor to drive the tubular mattress to move, and the patient can turn over at any angle of 0-360 degrees. Turning over less than 90 degrees does not require the presence of a caregiver. This method of turning over completely removes the patient's back from the bed. Autonomous defecation is the lifting of the bed in the leg with the push of the electric pusher, holding the patient's leg up and moving the patient's buttocks away from the mattress. The electric push rod of the toilet folding mechanism installed at the rear of the bed frame pushes the push arm to cause the toilet to be lifted up and down under the buttocks of the patient. Automatic cleaning and heat are installed on the toilet The function of air drying, the entire process does not require the hands of the nursing staff. BRIEF DESCRIPTION OF THE DRAWINGS:

The bed frame (2) is made up of two rectangular thin steel pipes which are welded in the corresponding parts of the back bed plate (7) and the hip bed plate (6), and are provided for the chain plate type bed and the rolling cylindrical mattress (10). Install and rotate the space. The front support plate (20) and the rear support plate (19) of the buttock plate (6) are screwed and attached to the rear of the recessed portion. The front frame of the bed frame (2) is welded with a front bed frame (11). The rear side is welded with a rear bed support frame composed of a leg middle plate (4) a leg side plate (5) and a foot bed plate (3). The rear bed panel falls above the support frame when it is not raised.

The bed of the nursing bed is divided into five sections, which are the headboard (9) the backboard (7) the hipboard (6) the middle bed of the leg (4) and the legboard of the legboard (5), the foot Bed board (3). The headboard (9) is a common bedboard, and the mattress is also an ordinary mattress. It is welded on the front bed frame (11) and the back bed plate (7) constitutes the front bed plate. The front bed plate bracket (U) is composed of two ears with ears. The support plate processed by the thin steel plate is welded with three square tubes. The shape and size of the ear are identical to those of the front support plate (20). A sliding hole bushing is mounted on the ear portion of the support plate, and the inner hole of the bushing is provided with a long chain roller (22). Sleeve outer hinged frame (24). The back plate (7) is identical in structure to the hip plate (6) except that there is no folding mechanism.

The hip plate (6) has no mounting bracket. All the components are installed in the middle of the rear support plate (19) and the front support plate (20). Two of the four short chain rollers (21) are mounted on the support plate ear. In the sliding sleeve, the other two are mounted on the side frame (24), and the side frame (24) is a curved plate formed by two thin steel sheets. The round pipe connecting rod is composed of a fixed pull rod in the middle of the chain plate, the round hole at the end of the curved plate is embedded with the sliding bush sleeve, and the short chain roller (21) is installed in the sleeve. The round hole at the corner of the curved plate is set on the front support plate. (20) With the rear support plate (19), the upper part of the sleeve can be rotated. Each of the two ends of the chain roller has a chain wheel that simultaneously drives one chain chain, and each chain link between the two chains fixes one chain plate. The chain plate is a small rectangular square tube composed of two nylon blocks pressed at both ends. There are two small holes on the end face of the nylon block, and the elongated chain shaft is matched with the small hole. The multi-section chain plate and the chain form a chain plate type bed board, and the front support plate (20) is provided with a chain plate motor (28) and two tension sprocket wheels to drive the two short chain rollers (21) to rotate through the transmission chain (29). The rear support plate (19) is welded with a shaft below, the upper side of the shaft is hinged to the side of the swing arm (26), the other end of the swing arm is hinged to the side frame link (25), and one end of the connecting rod is sleeved on the side frame (24). On the pipe connecting rod. The side frame (24) on each side is folded by a side frame electric push rod (27), and the two side frame electric push rods (27) are hinged to the bottom frame (2) with screws, and the pusher head is hinged. In the middle of the side frame swing arm (26).

The back plate (7) and the hip plate (6) are moved synchronously, and the front plate also has a folding action, so that the short chain roller (21) is designed to drive the universal joint between the long chain rollers (22), but The smallest universal joint shaft can't be installed in this position. The reason is that there is no gap after the two rollers are coaxial. Therefore, the ϋ-type card bent by two round wires is used to drive the torque. Achieve the function of the universal joint. The U-shaped universal drive card (23) is slidable in the two small holes in the center of the long chain roller (22) and the short chain roller (21). When the front bed is folded up, the U-shaped card needs to slide out a small section. The outer side of the thin support plate on the front bed frame (11) is welded with a hinge bushing, and the upper side of the rear support plate (19) is also welded with a hinge bushing hinged together through a small shaft, while the back bed plate (7) hip bed plate ( 6) The corresponding mattress is a cylindrical rolling mattress (10) which can continuously move around the bed. The folding of the front bed frame (11) is powered by the front bed folding electric pusher (15), after the putting The part is hinged to the top of the bed frame (2), and the pusher head is hinged to the front bed support (11).

The leg board is divided into three pieces, one leg middle plate (4) and two leg side bed plates (5), two leg side bed plates (5) and the bed frame (2) and the foot bed plate (3) hinged Connected. The foot board (3) has a connecting rod and a bed frame (2) hingedly connected to the rear part, a foot bed board folding electric push rod (16), a rear hinged bed frame (2), and the putter head is directly connected to the foot board ( 3) Above the welded struts. The foot bed folding electric push rod (16) can push the foot board (3) and the leg side board (5) to fold up. The middle plate (4) of the leg is not mounted on the foot board (3), but the middle part is hinged to the upper side of the leg. The support frame (39) can be rotated by 90 degrees. The leg midplane support (39) is hinged to the footboard (3) and is adjusted by the leg mid-lift electric pusher (17). Leg mid-plate support (39) Adjust the angle of the leg mid-plate (18) Adjust the angle of the bed (4) in the leg. When the leg middle plate (4) is raised, the leg of the patient is lifted up first. In this process, the angle of the bed plate (4) in the leg is adjusted to be the same as the leg of the patient, and if it rises to a certain height, The patient's buttocks are not far enough away from the mattress, and the foot folding electric pusher (16) can push the footboard (3) to continue to rise so that there is enough distance under the patient's buttocks to lower the toilet (35).

The toilet folding mechanism is composed of a toilet (35), a toilet mechanism swinging lever (31), a push arm (30) swinging shaft (32), and the like, and four sliding shafts are embedded on both end faces of the toilet mechanism chassis (33). The sleeves and the two pendulum shafts (32) are arranged in the front and rear in the sleeve. The pendulum shaft (32) has a keyway and pusher arm (30) in the middle and both sides, and the keyway on the swing lever (31) is fixed with a key. The toilet seat electric push rod (34) is hinged to the top of the toilet mechanism chassis (33) with screws. The pusher head articulated push arm (30) in the leg of the bed (4) raised the bed and the mattress creates space, the toilet mechanism electric push rod (34) pushes the push arm (30) the toilet mechanism swing lever (31) The motion-driven toilet (35) is inserted horizontally under the patient's buttocks, and the toilet folding mechanism is a single unit. The chassis fixing screws can be separated from the bed frame (2).

Since the backboard (7) and the hipboard (6) are provided with a chain plate, the corresponding mattress (10) is a cylindrical rolling mattress (10), which is rotated from below the bed. Therefore, the thickness of the two sections of the bed is twice that of the headboard (9). In order to facilitate the replacement of the mattress and the sheets, the guardrail should be received under the bedboard to give up the space of the cylindrical rolling mattress (10). The existing bed guardrail does not meet the requirements, and the volume after folding is too large, so only the double folding guardrail can be used. The guardrail upper frame (8) is parallel The quadrilateral design can be folded longitudinally and mounted on the frame mount (36). The lower folding frame swing arm (38) hinged guard frame seat (36) and the connecting fixing plate (37) lower folding frame can swing up and down. The guardrail takes up a small space after being put away, and can be received inside the bed board, which is more convenient for the patient to get on and off the bed. The two side rails of the bed head are fastened to the front bed frame (11) by the connecting fixing plate to move with the front bed board, and the bed tail guard rail is installed on the bed frame (2).

The various functions of the overall multi-functional automatic nursing bed are completed by eight electric push rods (the bed frame (2) is lifted at the same time with two) and an electric motor. The bed frame (2) lifting can be completed by the nursing staff manually operating the switch. Other actions are completely controlled by the single-chip computer. The speed of the turning movement, the length of time, and the number of turning over at night can be input into the MCU according to the patient's condition. The time action and the process of water rinsing and hot air drying are also automatically completed in advance on the MCU.
