The main purposes of using the nursing bed are: the patient can move on the bed conveniently, the pressure sore is prevented, and the nursing requirement is met. For completely self-unsupervised patients, some physical activities are required to be performed passively, and the body position or the pressed part of the patient is changed. The use of a nursing bed to prevent the occurrence of pressure sores is a primary objective; for patients who can do partial autonomous movement, not only the pressure sore needs to be prevented, but also some activities such as eating, reading, etc. can be performed on the bed. The nursing bed has various functions and great difference, such as body position adjustment, turning over, body pressure position change by using an air cushion, manual operation or electric control and the like. The two types of bed surfaces exist in terms of the number of bed plates and the adjustment between the bed plates, 1, the height (angle) between the bed plates cannot be adjusted, and the whole bed surface can only be adjusted (rotated); 2. the bed surface is segmented, and the bed plate consists of a plurality of plates, and the height (angle) between the bed plates can be adjusted.

Detailed Description

The nursing bed for the patient is only used for a short time, and the nursing bed for the patient needs a long time; some patients can not move autonomously at all, and some patients can move partially autonomously. The nursing bed is used in a hospital, the external condition is better, the using object is uncertain, and the needed functions are more; the nursing bed is used at home, the condition is limited, the used object is determined, the needed functions are fewer, and the use cost is low. The nursing bed is used as an appliance for nursing patients and is suitable for different needs of different patients. Therefore, the multifunctional inflatable nursing bed is designed to have various functions in order to meet different requirements of different patients, and can be selectively combined according to requirements. The position adjusting system of the multifunctional inflatable nursing bed can be manually operated or electrically controlled by an adjusting device, the electric control mode can be wired or wireless, the bed board can be an integral board, two long boards, four transverse boards and eight-block combined boards, a lifting adjusting device at the back of the head and the back of the bed board, a leg stretching adjusting device, a left turning adjusting device and a right turning adjusting device can be arranged, and different accessories (a movable dining table, a guardrail, an infusion support, a bedpan and the like) can be additionally added according to different requirements.

The bed board is placed on the bed frame, and the universal wheels are arranged at the lower ends of the bed legs. Except for the bed plate adopting the integral plate, the bed plates of the two long plates, the four transverse plates and the eight combined plates are correspondingly adjusted to meet the requirement of adjusting the body position of a patient. In order to carry out corresponding regulation to the bed board, set up corresponding adjusting device in the bed body, carry out relevant activity (displacement) through adjusting device control, regulation bed board within a definite time, reach the displacement between the regulation bed board, passive change patient's position, change patient's atress position, make things convenient for patient's activity, life.

Some functions of the nursing bed (the change of the body position of the patient) are realized by changing the mutual positions of the bed boards, so the function of changing the body position of the patient can be determined by adopting the number of the bed boards. The bed board can be selected from an integral board, two long boards, four transverse boards and eight-piece combined boards. When the bed plate is an integral plate, the bed surface can not be adjusted, and only the integral displacement of the bed surface can be carried out. When the bed board adopts two long boards, two long boards divide into left long board and right long board, and left and right bed board uses a certain straight line that is close to the bed central line as the axis and rotates, can realize the regulation of certain angle between left and right bed board, turns on one's side or the right side turns over to the patient that can not independently move the health, unconscious patient. The bed surface adopts four diaphragm, and four diaphragms divide into upper plate, intermediate lamella, lower plate (categorised two parts), and the intermediate lamella is the fixed plate, and certain angle can be raised to upper plate (backplate), lower plate (leg board), and the patient can carry out the lift of back of the head, the regulation of buckling of shank, and this is the most common ordinary sick bed at present. The bed surface adopts eight block plywood, and eight block plywood are left upper plate, left medium plate, left hypoplastron upper portion, left hypoplastron lower part, right upper plate, right medium plate, right hypoplastron upper portion, right hypoplastron lower part respectively, and eight blocks of boards can carry out the rotation of certain direction, through different combinations and regulation, the patient can carry out the lift of the back of the head, the stretching of leg, the left side of body is turned on one's side, the right side is turned on one's side. In order to ensure the synchronization of adjustment and reduce the number of adjusting devices, on the basis of ensuring the reliable adjustment among all the plates, in order to increase the interconnection among the plates, the displacement between the two plates is only the change of an angle, and when the distance is not changed, a hinge is additionally arranged between the connecting edges of the two plates. And a certain distance is left between the two plates, so that no friction or interference is generated during adjustment.

The adjusting device is a device for realizing the activity of the bed board and consists of a pushing part, an adjusting part and a limiting part. The pushing component can move in a linear direction and is connected with the bed plate to push the bed plate to lift one side; the front end of the adjusting component is controlled by manual operation or electric control to do circular (linear) motion, and the rear end of the adjusting component changes the circular motion into linear motion; the rear end of the adjusting part is connected with a pushing part to provide kinetic energy for displacement of the pushing part and control the movement (expansion) direction and the moving distance of the pushing part; the limiting component controls the range of motion of the bed board and plays a role in protection. The structure and principle of the adjusting device are basically the same as those of the existing nursing bed, the adjusting device can be driven by a gear or a rack or a worm, and the existing compressed air source of the multifunctional nursing bed can also be utilized and the air pressure (air pump) type is adopted. It is a common mature technology to control the displacement of the push rod by the pressure of gas or by an oil pump.

The adjusting device works through manual operation or electric control, the manual operation is related (the bed plate is lifted or lowered) through rotating (forward rotation or reverse rotation) a hand crank manually, and the electric control is realized through controlling the work of a motor and an air pump (an oil pump) through a control part. In order to limit the range of motion of the bed board, a limit component is arranged at a relevant position, and the limit component of electric control adopts a limit (travel) switch or a light-operated limiter; the manual control limiting component adopts a mechanical limiter.

At present, four transverse plate beds are most commonly used, and a head and back lifting adjusting device and a leg stretching adjusting device are partially arranged on a bed frame to be used as supporting points. The eight-block combined bed board is that four bed boards of the four-block transverse bed are cut into two from one bed board, and the lifting adjusting devices of the head and the back of the eight-block combined bed board, the stretching adjusting devices of the legs and the adjusting devices of the four-block transverse bed are basically the same in structure, but all the adjusting devices are installed on the bed boards and are not related to the bed frame. The head and back lifting adjusting device and the leg stretching adjusting device of the eight-block combined bed board take the left middle board and the right middle board as supporting points. The left side turning adjusting device and the right side turning adjusting device of the eight-block combined bed board are also partially arranged on the bed frame as supporting points.

The eight-piece combined bed adopts eight pieces of boards, namely the functions of two long board beds and four transverse board beds are combined, so that the patient can lift the head and back, stretch the legs, turn the body left and turn the body right. The eight combined plate beds are provided with a head and back lifting adjusting device, a leg stretching adjusting device, a left side turning adjusting device and a right side turning adjusting device, so that the functions of head and back lifting, leg stretching, left side turning and right side turning are realized. The eight plates are respectively a left upper plate, a left middle plate, a left lower plate upper part, a left lower plate lower part, a right upper plate, a right middle plate, a right lower plate upper part and a right lower plate lower part. The lifting of the head and the back, the stretching of the legs, the left turning and the right turning of the patient are carried out in the eight combined board beds, the left upper board, the left lower board, the right upper board and the right lower board need to rotate in two directions (transversely and longitudinally), the left middle board and the right middle board only need to rotate in one direction (longitudinally), and the left upper board, the left lower board, the right upper board and the right lower board can be driven or pushed to move by taking the left middle board and the right middle board as central positions (reference points).

Adjusting the bed plate: because the left upper plate and the right upper plate are connected through the hinge, the left upper plate and the right upper plate have certain connecting and fixing effects, and a set of adjusting device can be adopted, so that the left upper plate drives the right upper plate to move together or the right upper plate drives the left upper plate to move together. The upper end of the left middle plate or the right middle plate is provided with an adjusting part of a lifting adjusting device at the head back part, and one end of a pushing part of the lifting adjusting device at the head back part is fixedly arranged on the left upper plate or the right upper plate. Or two sets of adjusting devices can be respectively arranged between the left upper plate and the left middle plate and between the right upper plate and the right middle plate, and the two sets of adjusting devices can be simultaneously and synchronously adjusted to ensure the synchronous movement of the left upper plate and the right upper plate. The upper plate takes the middle plate as a fixed supporting point, the outer edge of the upper plate is raised or lowered, and a certain angle change is formed between the upper plate and the middle plate, so that the head and the back of the patient are raised or lowered.

Adjusting the bed plate: similarly, because the left lower plate and the right lower plate are connected through the hinge, the left lower plate and the right lower plate have certain connecting and fixing effects, and a set of adjusting device can be adopted, so that the left lower plate drives the right lower plate to move together or the right lower plate drives the left lower plate to move together. An adjusting part and a pushing part of the leg stretching adjusting device are arranged between the upper part and the lower part of the left lower plate or the right lower plate. Two sets of adjusting devices can be arranged in the left lower plate and the right lower plate respectively, and the two sets of adjusting devices can be used for adjusting simultaneously and synchronously, so that the synchronous movement of the left lower plate and the right lower plate is ensured. The joint of the middle plate and the lower plate is provided with a hinge, the lower plate takes the middle plate as a fixed supporting point, the upper part of the lower plate is connected with the lower part of the lower plate by the hinge, and when the upper part of the lower plate and the lower part of the lower plate move relatively when the adjusting device is started, the upper end of the upper part of the lower plate cannot move horizontally due to the fixing effect of the middle plate. When the bed board is in a horizontal position, the stretching adjusting device of the legs adjusts, the lower end of the upper part of the lower board moves upwards, the joint of the upper part of the lower board and the lower part of the lower board moves upwards, the upper part of the lower board, the lower part of the lower board and the bed frame form a triangle, the upper part of the lower board and the middle board form a certain angle, meanwhile, the upper part of the lower board and the lower part of the lower board also form a certain angle, and the upper part of the lower board, the lower part of the lower board and the bed. Adjustment in the opposite direction straightens the patient's curved leg.

Adjustment of the bed left plate and the bed right plate: the left middle plate and the right middle plate are fixed when the left upper plate, the left lower plate, the right upper plate and the right lower plate move (the head and the back of a patient rise and fall and legs stretch), can play a role of foundation (fixation), but also rotate when the left side and the right side turn over. Two support columns are arranged on the right side of the left middle plate and the left side of the right middle plate, the support columns are cuboid, a round hole is formed in the lower portion of each support column, the upper ends of the support columns are installed below the left middle plate and the right middle plate, a bolt shaft penetrates through the round holes of the two support columns in the left middle plate and the right middle plate, and the bolt shaft is a cylinder; two ends of bolt axle are fixed in the installing frame, and through the round hole of support column and the cooperation of bolt axle, when raising on the left of left medium plate, the right of right medium plate, left medium plate, right medium plate can use the bolt axle to rotate as the fulcrum. The left and right sides of the mounting frame are provided with a left side turning adjusting device and an adjusting part of a right side turning adjusting device, the pushing part is connected to the left side of the left middle plate and the lower part of the right two ends of the right middle plate and is symmetrical to the right side of the left middle plate and the left side of the right middle plate, when the pushing part of the left middle plate displaces (ascends and descends), the left side of the left middle bed plate has certain displacement (ascends and descends), at the moment, the right side of the left middle plate rotates by taking the bolt shaft as a central axis, and the left middle plate and the right middle plate form a certain included angle; likewise the right middle plate may be adjusted. Because the middle plate is provided with the upper plate adjusting device and the connecting (hinge) part of the middle plate and the upper plate and the lower plate, the four plates on the left side are connected into a whole by utilizing the fixing and connecting functions of the adjusting device and the connecting (hinge) part, when the left middle plate (right middle plate) displaces, the other three plates on the left side (right side) are necessarily driven to displace together, and the synchronous displacement (lifting and descending) on the left side or the right side is realized just like a two-long-plate bed. Because two adjusting devices work when the left side is turned over and the right side is turned over, two power sources are needed, and the two adjusting devices are connected through a transmission shaft for cooperative work, one power source drives the transmission shaft to rotate, and the transmission shaft drives the two adjusting devices to work together.
