[0001] The invention belongs to the technical field of intelligent mattresses, and in particular relates to a rehabilitation nursing bed with intelligent body position conversion and a control method. Background Art

[0002] Mattresses are the most frequently used mattresses in people's daily lives. Existing mattresses are generally divided into one-piece spring mattresses, independent pocket spring mattresses and zoned spring mattresses. One-piece spring mattresses use a whole-surface one-piece spring, and the bed surface is relatively hard, which is basically impossible to fit the curve of the human body. Independent pocket spring mattresses use independent springs, and the bed surface is moderately soft and hard, but independent pocket spring mattresses cannot provide independent force support for specific parts of the human body. Zoned spring mattresses use springs with different support forces in different zones of the mattress, which can provide support for the head, neck, shoulders, waist, buttocks, legs, feet and other parts of the human body, but people's height, weight and sleeping posture are often different. The zoned spring mattress cannot provide targeted support for people of different heights and weights and different sleeping postures;

[0003] Traditional mattresses can usually only adjust the height of the head and foot of the bed, and the angle and curvature of the bed surface have a small adjustment range and cannot meet the different nursing needs of patients; therefore, there is an urgent need for a rehabilitation nursing bed that can intelligently change body positions.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The present application provides a rehabilitation nursing bed with intelligent body position conversion, referring to Figure 1 and Figure 5 , including a bed board and an intelligent control system, the bed board is sequentially provided with a No. 1 airbag layer 2 and a No. 2 airbag layer 3 from top to bottom; each airbag in the No. 1 airbag layer 2 and the No. 2 airbag layer 3 is connected to a pneumatic system;

[0040] The first airbag layer 2 includes a plurality of first airbag groups 21 arranged transversely;

[0041] The second airbag layer 3 includes a plurality of second airbag groups 31 arranged vertically;

[0042] The positions of the plurality of No. 1 airbag groups 21 and the plurality of No. 2 airbag groups 31 correspond one to one, and both the No. 1 airbag group 21 and the No. 2 airbag group 31 are symmetrically divided into left and right parts along the midline of the human body;

[0043] A data acquisition module is provided on the first airbag layer 2; the intelligent control system is connected with the data acquisition module and the pneumatic system.

[0044] The horizontal arrangement spacing of the No. 1 airbag group 21 in the No. 1 airbag layer 2 can be 50mm, forming a uniform support layer to provide basic support and pressure dispersion; the airbags in the No. 1 airbag group 21 can be adjusted to other different shapes to ensure the comfort of the patient; the vertical arrangement density of the No. 2 airbag group 31 in the No. 2 airbag layer 3 can be 30mm, which is convenient for fine position adjustment, responsible for fine position adjustment and support for specific areas; by dynamically and alternately adjusting the pressure in the No. 1 airbag layer 2 when a normal patient lies for a long time, the system is started to periodically inflate and deflate the No. 1 airbag layer 2 to change the patient's contact point, promote blood circulation, and reduce the probability of bedsores; when the patient needs to change his position, the corresponding position of the No. 2 airbag layer 3 is inflated and raised to form a height difference, and work together with the No. 1 airbag layer 2 to adjust the height and angle of different parts to achieve patient position tilt, and help patients adjust their position, such as head lifting, pelvic tilting, etc.; at the same time, personalized comfort adjustment can be provided to improve sleep quality;

[0045] The data acquisition module collects the patient's pressure distribution, body temperature and humidity data. The data acquisition module includes multiple sensors, such as pressure sensors, body temperature sensors, humidity sensors and other types of sensor networks. The sensor data is processed by the microcontroller in the intelligent control system and the air pump and air valve in the pneumatic system are controlled to adjust the air pressure of the airbags in airbag group No. 1 21 and airbag group No. 2 31; combined with the patient's body shape and nursing history data recorded in the AI ​​module; the AI ​​module provides personalized body position adjustment plans according to the patient's condition, recommends the best body position at regular intervals, analyzes the patient's needs, and generates body position adjustment instructions.

[0046] When the patient's body position is adjusted according to the user's needs or the recommended optimal body position instruction; by starting the pneumatic system, the system drives part of the second airbag group 31 to rise, so that the first airbag layer 2 forms an inclined state, assisting the patient's body position to form an inclined state, and then converting the body position;

[0047] A variety of care modes are designed for different patient groups. For example, the postoperative rehabilitation mode can focus on supporting the postoperative trauma site, reducing the risk of trauma recurrence by reducing pressure and stabilizing support; the osteoporosis protection mode can reduce the burden on bones and optimize the pressure distribution in the hip and waist areas; the bedsore high-risk mode adopts a dynamic alternating pressure mode, which changes the patient contact point through periodic inflation and deflation, promotes blood circulation, and reduces the incidence of bedsores. These specific disease modes provide targeted care solutions for patients with different diseases, improving the applicability and care effect of the mattress;

[0048] The main body of the present invention is an airbag cushion, which is lightweight and portable and can be applied to different environmental scenarios, such as hospitals, homes, outdoors, etc., making it convenient for patients to use it in different occasions, improving the flexibility and practicality of the mattress and being able to meet diverse care needs.

[0049] The present application facilitates fine body position adjustment through the vertically arranged No. 1 airbag layer 2 and the horizontally arranged No. 2 airbag layer 3, which is responsible for detailed body position adjustment and support for specific areas. This double-layer design allows the mattress to finely adjust the user's body position, providing more complex body position adjustment and support capabilities to adapt to different nursing needs and ergonomic requirements, providing patients with more accurate and personalized support and care.

[0050] On the basis of the above embodiment, on the basis of the first airbag layer 2 and the second airbag layer 3, a combination of three or more airbag layers can also be used. For example, a layer of obliquely arranged airbags is added between the first layer of horizontally arranged airbags and the second layer of vertically arranged airbags. The obliquely arranged airbags can further refine the accuracy of body position adjustment and provide patients with more complex support and pressure dispersion effects to meet special care needs. For example, for patients with more severe scoliosis, the oblique airbags can better fit the curvature of their spine and provide targeted support.

[0051] At the same time, the shapes of the airbags in the No. 1 airbag layer 2 and the No. 2 airbag layer 3 can be changed. In addition to round or oval airbags, they can also be designed into square, diamond, triangle and other airbags of different shapes, and these airbags of different shapes can be reasonably matched and arranged. For example, square airbags are used in the head control area and shoulder control area to provide more stable support; diamond airbags are used in the upper limb control area and lower limb control area to facilitate angle adjustment and pressure dispersion; triangular airbags are used in the spine control area and pelvis control area to better fit the human body curve and enhance support and protection for key parts;

[0052] Introducing deformable airbags, the shape and size of which can be automatically adjusted in real time according to the patient's body contours and care needs. For example, an airbag made of memory material can automatically sense and adapt to the shape of the patient's body when the patient lies on the mattress, forming a support surface that is highly fitted to the patient's body, reducing pressure concentration points and improving the patient's comfort. At the same time, through the intelligent control system, the deformation degree of the deformable airbag can also be precisely controlled to achieve more sophisticated posture adjustment and care functions.

[0053] In one embodiment of the present invention, reference Figure 2, where ab is the head curve, cd is the shoulder area, ef is the upper limb area, gh is the spine area, ij is the pelvic area, and lm is the lower limb area; the multiple No. 1 airbag groups 21 and No. 2 airbag groups 31 are arranged in corresponding partitions according to the head area, shoulder area, upper limb area, spine area, pelvic area and lower limb area.

[0054] The human body is divided into 12 control areas, each of which can be controlled individually to meet the support and care needs of different parts of the body; the airbags in each control area can be inflated and deflated independently to achieve highly customized body position adjustment. It can achieve body position conversion of small joints and small areas or good limb position placement;

[0055] At the same time, the plurality of No. 1 airbag groups 21 and No. 2 airbag groups 31 may be arranged in corresponding zones according to the respiratory system support zone, the circulatory system protection zone, and the nervous system care zone.

[0056] The distance between the first airbag groups 21 can be adjusted by a telescopic component, so that the positions of the airbags therein can be adjusted at will, thereby forming different partitions;

[0057] The respiratory system support area is mainly concentrated in the chest and upper abdominal areas. Through special airbag design and inflation and deflation patterns, it helps patients keep their airways open, promotes lung expansion, and relieves symptoms of dyspnea. The circulatory system protection area focuses on the heart and lower limb blood vessel areas, and uses pressure gradient control technology to promote blood circulation and prevent thrombosis. The nervous system care area is mainly concentrated in the head, neck and spine areas. Through precise body position adjustment and pressure control, it reduces nerve compression, relieves pain, and promotes nerve function recovery.

[0058] According to the stage of care the patient is in, the mattress is divided into acute care area, rehabilitation care area and recovery care area. The acute care area is mainly for patients with more serious conditions who need close monitoring and emergency treatment. The airbag design and control system in this area can respond quickly and provide emergency support and position adjustment functions, such as rapid inflation to prevent patients from falling out of bed, adjusting the position to keep the airway open, etc.; the rehabilitation care area focuses on the patient's rehabilitation training and functional recovery. The airbag can perform more precise position adjustment and pressure control, and cooperate with rehabilitation treatment equipment to provide patients with personalized rehabilitation support; the recovery care area focuses more on providing a comfortable sleeping environment and assisting patients in daily activities. The hardness and support of the airbag can be gradually adjusted according to the patient's recovery to help patients better adapt to normal life.

[0059] Considering the great differences in the physical conditions and nursing needs of different patients, a personalized functional zoning solution is provided. Patients or medical staff can freely divide and define the functional zoning of the mattress through the intelligent control system according to the patient's specific condition, physical characteristics and nursing goals. For example, for a patient with severe shoulder disease who needs to stay in bed for a long time, the shoulder area can be divided into a separate functional area, and the airbags in this area can be specially set, such as increasing the inflation pressure range of the airbags, setting specific inflation and deflation modes, etc., to better meet the patient's nursing needs and improve the patient's comfort and nursing effect.

[0060] When the stroke patient's position needs to be adjusted, the stroke patient's position conversion and good limb position placement are input on the display screen connected to the intelligent control system. The intelligent control system recommends the best position and pressure distribution based on the patient's body shape, nursing history data and real-time physical condition through the built-in AI module. The intelligent control system can provide personalized position adjustment plans based on the patient's condition (such as stroke, scoliosis, postoperative rehabilitation). At the same time, the data acquisition module in the AI-assisted mode collects the patient's pressure distribution, body temperature and humidity data. Then perform model calculation: The AI ​​module uses a trained deep learning model (such as a convolutional neural network) to analyze the patient's needs and generate position adjustment instructions. Position implementation: The intelligent control system adjusts the airbag pressure and inflation mode of the corresponding area according to the AI ​​instructions;

[0061] When it is necessary to place the stroke patient in a good limb position, supine position: the head area is raised and the height is adjusted by inflating and deflation of the vertical airbags, the neck is kept in a neutral position, and excessive flexion or extension is avoided. The shoulder area is raised and the vertical airbags are inflated and deflated to adjust the height, so that the scapula is pushed forward and the scapula is prevented from retracting. This can prevent the shoulders from being suspended in the air, reduce shoulder discomfort, and also facilitate blood circulation in the upper limbs. When the upper limbs are placed, the shoulder joint is abducted by about 45°-60°, the elbow joint is extended, the forearm is supinated, the wrist joint is dorsiflexed, and the fingers are extended. This can prevent flexion contracture of the upper limbs and promote the recovery of upper limb function. In terms of the lower limbs, the hip joint is extended, the knee joint is slightly flexed, and the foot is kept in a neutral position. The airbags in the lower limb area are inflated and deflated to make the knee slightly flexed to prevent excessive extension of the knee joint and also to prevent foot drop.

[0062] Lying position on the affected side: The affected side is at the bottom, and the airbag on one side of the head area is inflated and raised to form an inclined angle on the plane of the head area, thereby making the head slightly forward, keeping the neck natural and comfortable. The shoulder girdle of the affected side is extended forward, the shoulder joint is flexed about 90°, the elbow joint is straightened, the forearm is supinated, the wrist joint is dorsiflexed, the fingers are extended, and the palm is facing up. The upper limb of the healthy side can be placed naturally on the body or on a pillow. The hip and knee joints of the affected lower limb are flexed, and the healthy lower limb is at the back, with the hip and knee joints slightly flexed. A small pillow can be clamped between the two legs to prevent the affected lower limb from being compressed. This posture is beneficial to the blood circulation of the affected limb, and can also prevent the affected limb from being compressed for a long time and causing discomfort.

[0063] Lying position on the healthy side: The healthy side is on the bottom, the head is slightly backward, and the neck is kept comfortable. The shoulder joint of the affected side is forward, the upper limb is extended forward, the elbow joint is straight, the forearm is supinated, the wrist joint is dorsiflexed, and the fingers are stretched and can be placed on a pillow. The hip and knee joints of the affected lower limb are flexed and placed in front of the healthy lower limb. A small pillow can also be placed between the legs to prevent the affected lower limb from external rotation. The healthy lower limb is straightened, which can maintain a good posture of the affected limb and promote functional recovery.

[0064] For patients who have undergone hip replacement and fractures and other patients who need good limb positioning and body position change, the same principle can be used to place the patient's body parts, especially damaged limbs, in a correct posture and position that conforms to physiological functions, is conducive to disease recovery and prevents complications.

[0065] When the stroke patient's body position needs to be changed, the patient in the supine position lies on the No. 1 airbag layer 2, and the No. 2 airbag group 31 on the healthy side of the head area is controlled to rise, so that the head area forms an inclined surface with the healthy side higher and the affected side lower, thereby helping the patient's head to rotate toward the affected side, and the thoracic spine must not be flexed; then adjust the upper limbs, inflate the No. 2 airbag group 31 below the scapula in the patient's upper limb area, and help the patient maintain shoulder extension and external rotation; then adjust the lower limbs, inflate the No. 2 airbag group 31 below the affected hip in the affected lower limb area, so that the affected pelvis protrudes forward, and inflate the No. 2 airbag group 31 in the area below the knee on the affected side to keep the affected knee slightly flexed and the toes facing upward, prevent knee reflexion, and inhibit lower limb extensor spasm;

[0066] Then, the patient is assisted to move his body to the healthy side, and the healthy hand can be supported at any place; then, all the No. 2 airbag groups 31 in the healthy area are inflated and raised to form a height difference between the healthy area and the affected area to help the patient turn over, so that the patient lies on his side, with the affected side at the bottom and the healthy side at the top; after the successful turning over, the healthy limbs are assisted to be adjusted, and the healthy upper limbs can be placed on the body or slightly behind. The healthy lower limbs are kept in a stepping posture, placed on a pillow, and the knee and ankle joints are slightly flexed.

[0067] In one embodiment of the present invention, the plurality of first airbag groups 21 are connected by highly elastic fabric.

[0068] During the implementation process, the coordinated operation and smooth transition between the No. 1 airbag group 21 are ensured by using high-elastic fabric connections.

[0069] In one embodiment of the present invention, reference Figure 4 The bed board includes a lower bed board 11, an upper bed board 12 and side boards 13; the two side boards 13 are fixedly mounted on both sides of the lower bed board 11;

[0070] Flexible plates 5 are connected to both sides of the upper bed board 12, and mounting grooves 6 are provided on the side boards 13, and one end of the flexible plate 5 is located in the mounting groove 6;

[0071] The lower bed board 11 is provided with a moving mechanism 4, which drives the upper bed board 12 to drive the flexible board 5 to move horizontally between the two side boards 13; the upper bed board 12 is provided with a second airbag group 31 and a first airbag group 21 in sequence;

[0072] The head and tail ends of the No. 1 airbag group 21 are fixedly connected to the head and tail ends of the upper bed board 12 ; the two sides of the No. 1 airbag layer 2 are connected with a supplementary layer 8 , and the supplementary layer 8 is slidably connected to the side plate 13 .

[0073] When the patient's body position is changed, the left and right sides of the bed are respectively in area one and area two; when the patient is in a supine position, the two sides of the body are respectively located in area one and area two corresponding to the No. 1 airbag layer 2; the healthy side of the patient is located in area one, and the affected side is located in area two; when the patient is to be changed from a supine position to a healthy side position; firstly, the No. 2 airbag group 31 of the affected side head area of ​​the second area is inflated and raised, so that the head area forms an inclined surface with the affected side higher and the healthy side lower; then, the upper limbs are adjusted to inflate the No. 2 airbag group 31 below the scapula of the second area, so that the patient keeps the shoulder extended and externally rotated; then, the lower limbs are adjusted;

[0074] Then, the moving mechanism 4 is started, and the moving mechanism 4 drives the upper bed board 12 to move horizontally toward the second area, thereby driving the healthy side of the patient to move from the first area to the middle position close to the entire bed board, and then the second airbag group 31 under the second area is started to inflate all to form a height difference, so as to turn the patient over;

[0075] When the moving mechanism 4 drives the upper bed board 12 to move from left to right, the flexible plate 5 on the right side enters the installation groove 6, and the flexible plate 5 on the left side is in the same plane with the upper bed board 12, supporting the No. 2 airbag layer 3; the upper bed board 12 drives the No. 1 airbag layer 2 to translate, and the right side of the No. 1 airbag layer 2 slides downward along the side plate 13, and the left side of the No. 1 airbag layer 2 slides upward along the side plate 13, and the No. 1 airbag group 21 on both sides fills the position of the No. 1 airbag group 21 on the plane of the bed, ensuring the support when the patient is automatically translated; at the same time, when the moving mechanism 4 drives the patient to move, the speed of movement can be controlled and adjusted at any time, avoiding the problem of secondary injury to the patient when the human body assists in the translation of the patient.

[0076] In one embodiment of the present invention, reference Figure 4 and Figure 5 The flexible plate 5 includes a connecting plate 51 and a rotating shaft 52; the multiple flexible plates 5 are rotatably connected through the rotating shaft 52, and the flexible plate 5 at the head end is connected to the upper bed board 12.

[0077] In one embodiment of the present invention, reference Figure 3 The moving mechanism 4 includes a motor 41 and a gear 42. The motor 41 is fixedly mounted on the lower bed board 11, and the output end of the motor 41 is connected to the gear 42. The lower end of the upper bed board 12 is provided with gear teeth; the gear 42 is meshed with the gear teeth.

[0078] During the implementation process, when the patient's body position needs to be translated, the motor 41 is controlled to start, and the motor 41 drives the gear 42 to drive the upper bed board 12 to move left and right, thereby realizing the transfer of the patient's body position; when the flexible plate 5 and the rotating shaft 52 move to a planar state, they support the No. 2 airbag layer 3.

[0079] In one embodiment of the present invention, reference Figure 5 A support frame 7 is fixedly installed between the two side panels 13 , and a partition hole 71 is provided on the support frame 7 . The position of the partition hole 71 corresponds to the partition position of each No. 2 airbag group 31 .

[0080] The function of the support frame 7 is, on the one hand, to ensure that the second airbag group 31 extends vertically upward when the second airbag layer 3 is inflated; at the same time, when the upper bed board 12 drives the first airbag layer 2 to move left and right, the support frame 7 limits the various partitions of the second airbag layer 3; so that the second airbag layer 3 does not move with the upper bed board 12, so that after the patient's body position is translated, the second airbag layer 3 can still push the corresponding partition to turn over; at the same time, the support frame 7 is arranged at the lower part of the second airbag layer 3, specifically, it can be one-third of the distance from the bottom of the second airbag layer 3, to avoid the support frame 7 causing discomfort to the patient; at the same time, the support frame 7 can also adopt a grid structure, each airbag in the second airbag layer 3 corresponds to a grid, so that the airbag can maintain its height during the inflation process and avoid skewing due to changes in air pressure. The support frame 7 can be made of flexible plastic or metal wire, and has sufficient flexibility to adapt to changes in the airbag shape. The grid structure can ensure that the longitudinal airbag remains vertical when inflated.

[0081] In one embodiment of the present invention, the surface of the airbag in the first airbag layer 2 is made of silver ion antibacterial material. The surface coating uses advanced highly breathable antibacterial material to allow air to flow freely on the surface of the first airbag layer 2, avoiding the stuffy feeling and humid environment caused by long-term contact, and providing patients with a more comfortable and dry use experience;

[0082] The present application provides a control method for a rehabilitation nursing bed with intelligent body position conversion, which uses the above-mentioned rehabilitation nursing bed with intelligent body position conversion, and specifically includes the following steps:

[0083] The pneumatic system is started to inflate part of the second airbag group 31;
