DETAILED DESCRIPTION

[0035] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0036] Example:

[0037] The present invention provides an electric rehabilitation nursing bed, comprising a nursing bed 1 and a supporting mechanism 101, a bearing frame 102 is installed between the nursing bed 1 and the supporting mechanism 101, and the nursing bed 1 comprises a fixed frame 103, a headboard, a footboard and armrests; a conventional nursing bed 1 may also be provided with a rotating shaft, so that Figure 1 The multiple block structures shown can be rotated, for example, the left and right block structures are flipped, or the front and back block structures are flipped, etc. If necessary, other fixed structures or motors can be added, that is, Figure 1 The lifting and electrically movable device provided at the supporting mechanism 101 can meet the requirements of different functions.

[0038] Furthermore, a bed plate 2 is disposed at the top of the fixed frame 103, and a strip unit 3 is disposed inside the bed plate 2, and the strip units 3 are arranged at equal distances, and a vertical bar 201 is connected between the strip unit 3 and the bed plate 2, and the strip unit 3 includes a flexible layer (301) and a travel layer (302) located below the flexible layer (301), wherein:

[0039] Both ends of the flexible layer 301 include fixed ends 303 for installation, and an elastic portion 304 provided with a flexible material in the middle;

[0040] The upper surface of the travel layer 302 is provided with a sliding groove 305, and a protruding block 306 for reciprocating movement is installed inside the sliding groove 305, and the protruding block 306 is used to intermittently push the elastic part 304 upward;

[0041] like Figure 1-4 As shown, the strip units 3 designed on the multiple bed panels 2 are all independently arranged, and the installed travel layer 302 can be fixed at a certain position of the sliding groove 305 after the internal protruding block 306 moves back and forth, or repeatedly reciprocates. This method can lift up the upper flexible layer 301 so that the bedding is forced to push up, so that the target area of ​​the patient can move according to the action of the equipment or be clamped in the opposite direction by different protruding blocks at the front and back, so that the patient's limbs can move repeatedly and produce muscle stretching, or the limbs can be directly fixed on the bed panel 2 to complete the expulsion and massage and exercise of the patient's limbs; or when the patient is in a sitting position, the upwardly-pushing structure can also provide support under the feet to prevent the patient from moving downward due to small movements.

[0042] Furthermore, the flexible layer 301 and the travel layer 302 are installed to the surface of the vertical bar 201 by threads passing through the upper and lower ends, and the vertical bar 201 is fixedly connected to the bed body plate 2; the middle part of the top of the raised block 306 includes an electric telescopic rod 307, and a blocking strip 308 is provided on the middle side of the bottom end of the elastic part 304, and the position of the blocking strip 308 is set corresponding to the electric telescopic rod 307; the electric telescopic rod 307 provided on the raised block 306 can control the rising and falling distances, and the blocking strip 308 provided can also reduce the force-bearing area of ​​the elastic part 304 on the basis of rising, and the increase The added electric telescopic rod 307 can also make the upward lifting structure allow multiple bed panels 2 to be combined into different shapes, so that the patient can lie in it to fix his position or prevent him from falling under the bed. The multiple raised blocks 306 can be combined front and back into a left-right staggered structure with a slope. After putting a pillow on the surface, the patient's legs can be raised to a certain height, which can not only fix the position of the pillow, but also adjust the angle of the slope when necessary. When the raised blocks 306 are not used, because the surface is covered with the flexible layer 301, a certain degree of softness can also be provided.

[0043] Furthermore, the protruding block 306 and the sliding groove 305 move left and right through the ball screw 309, a gap is left between the flexible layer 301 and the travel layer 302, the elastic part 304 is made of rubber or wire mesh material, and the barrier strip 308 is concave and fixedly connected to the elastic part 304, and the bottom of the fixed end 303 and the two ends of the travel layer 302 are sleeved; the ball screw 309 provided can more finely control the distance that the protruding block 306 can move, and the ball screw 309 includes a motor for driving, such as Figure 4 At the left end of the travel layer 302, and because there is a gap between the flexible layer 301 and the travel layer 302 under normal conditions, the gap will disappear due to pressure after the patient lies down, and the airflow inside the sliding groove 305 will be weakened. Subsequently, the pushing effect generated by the protruding block 306 can increase the entry of airflow upward, forming an airflow movement inside the bed body block 2, thereby increasing the breathability of the bedding.

[0044] In another embodiment, a breathable layer 4 is further provided at the bottom end of the travel layer 302, a breathable grid 310 is installed at the bottom end of the sliding groove 305, a wind hole 401 is penetrated through the top surface of the breathable layer 4, a slot 402 is provided at the edge of the wind hole 401, the slot 402 is used to connect the breathable grid 310, ventilation pipes 403 are provided at both ends of the breathable layer 4, and the ventilation pipes 403 are connected to the air pump device 5; the air pump device 5 is embedded and installed on the inner side of the bed body block 2, an air outlet is provided at the bottom of the air pump device 5, and the air outlet is located at the vertical projection of the fixed frame 103 and has a slot, and multiple breathable layers 4 are connected to the air pump device 5 through the ventilation pipe 403, and the air pump device 5 contains a heating module, a wind pump unit and a pipeline filter;

[0045] like Figure 4 , 6 As shown in FIG. 7 , bedsores are mainly caused by the pressure of the body, the shear force and friction force on the skin surface, and the moisture of the skin. The above structure only solves the problem of pressure. The moisture of the bedding and the skin is only generated by the thrust formed by the electric telescopic rod 307 to generate air flow. It is sufficient for use in normal sleeping conditions, but it will still cause bedsores for patients who are bedridden for a long time. Even if the bed sheets are changed frequently and the body is turned over frequently, the skin will still be moist. Therefore, the air permeable layer 4 structure is further designed. Because the bed plate 2 is a block structure, it moves as a unit of the bed plate 2 when moving. Therefore, the air pump device 5 is embedded and fixed on a single bed plate 2 during design.

[0046] like Figure 2 , 7 As shown, the symmetrical air pump device 5 will draw the air from the air outlet through the internal air duct structure, through the pipe filter and the heating module, into the ventilation pipe 403. The heating module can be a structure such as a resistance wire heating or a semiconductor heating plate. Then, based on the air permeable layer 4 connected to the ventilation pipe 403, the air will flow upward from the air hole 401 and upward from the air permeable grid 310 at the bottom of the sliding groove 305. At this time, there will be two different flow directions. One is the elastic part 304 of the wire mesh material, which can openly blow hot air upward to the bedding, increase the air circulation of the bedding, reduce the humidity of the bedding, and keep the patient's skin in the quilt in a dry state; the other is the elastic part 304 of the rubber material. At this time, the air flow will be blown out from the gap between the flexible layer 301 and the travel layer 302, and the air will flow upward from the gap between the strip units 3. This method can increase the upward air pressure and reduce the humidity in the bedding. With the above structure, the probability of bedsores in patients can be further reduced.

[0047] Furthermore, the nursing bed 1 includes a main control unit, which includes an MCU microcontroller chip, a clock chip and a storage module. A pressure sensor 6 is also provided at the top of the supporting frame 102, and a camera unit 7 is also provided at the footboard of the nursing bed 1. After the setting, when the patient leaves the nursing bed 1, the pressure sensor 6 and the camera unit 7 can cross-verify whether the patient has completely left the bed, and calculate whether the bedding can be dehumidified by the last leaving time recorded by the storage module.

[0048] Then, the pressure sensor 6 compares the weight of the bedding on the bed plate 2 after the patient has used it this time with the overall weight of the bedding on the bed plate 2 after the last treatment. When a large difference appears, it means that the bedding is too wet. At this time, the air pump device 5 will start the heating module and the wind pump unit to a greater extent, so that the temperature and wind force can rise to a state of rapid drying, so that the hotter temperature can quickly take away the moisture in the bedding, and gradually lower the temperature until the temperature is at a suitable state, while maintaining a certain degree of heat to prevent moisture from adhering to the surface of the bedding again in a short period of time.

[0049] The fixed frame 103 is formed by splicing more than two bed panels 2, and the main control unit is electrically connected to the pressure sensor 6, the camera unit 7, the protruding block 306 and the air pump device 5, respectively. Figure 1 As shown, the flip angles of the multiple bed panels 2 can be controlled by the main control unit, and the main control unit can uniformly control the operation time of different devices and the operation plan of the devices, and can also store the plan in the storage module.

[0050] In another embodiment, a system of an electric rehabilitation nursing bed, the nursing bed 1 comprises a movable support mechanism 101, a fixed frame 103, a bed body block 2, a headboard and a footboard, which are used to carry a camera unit 7, a main control unit, an air pump device 5 and a bar unit 3 respectively, wherein:

[0051] The main control unit includes an MCU microcontroller chip, a clock chip, a wireless connection module and a storage module. The MCU microcontroller chip includes a touch screen for control; the clock chip is used to control the start and stop timing of the air pump device 5 and the bar unit 3 respectively; the storage module is used to save nursing plans with different control sequences;

[0052] The air pump device 5 includes a heating module, an air pump unit and a pipeline filter. The heating module includes a temperature sensing unit, which is used for the main control unit to control the heating module according to the temperature. The air pump unit is one of a micro diaphragm air pump, a peristaltic air pump and a linear piston air pump, and is symmetrically connected to the strip unit 3 from top to bottom.

[0053] The strip unit 3 includes a flexible layer 301, a travel layer 302 and a breathable layer 4. The travel layer 302 includes a protrusion 306. The flexible layer 301 is used to cooperate with the protrusion 306 of the travel layer 302 to form an intermittent upward push-up action. The breathable layer 4 is used to increase air circulation upward through the air pump device 5.

[0054] The camera unit 7 is installed at the footboard of the bed, and is used to photograph the face of the nursing object on the nursing bed 1 and perform facial recognition, and transmit the data to the storage module, and call out the nursing plan for use according to the plan recorded in the storage module.

[0055] The camera unit 7 also includes a microphone for recording the facial emotions and voice of the care recipient in conjunction with facial recognition, and locating the actions of different care plans; the main control unit includes an LDA algorithm, which collects and summarizes the actions of the care plan based on the Bayesian algorithm to achieve a combination of different care actions.

[0056] Furthermore, the system is mainly controlled by the main control unit. In normal use, the touch screen or buttons are used to operate it, such as controlling the movement of the bar unit 3 and controlling the start and stop scheme of the bar unit 3. When performing special treatments, such as different injured and sick patients, the corresponding facial information can be captured by the camera unit 7, that is, the convex shapes of the bed body panels 2 are automatically adjusted to different patients, so that rehabilitation workers can perform rehabilitation physiotherapy, rehabilitation massage and other operations on different patients on the same nursing bed 1.

[0057] For patients who need to use the nursing bed 1 for massage, or patients who need to lie on the nursing bed 1 for a long time, the main control unit includes an LDA algorithm, which can record the data that has occurred and predict the trend, and analyze the facial expression of the patient according to the image taken by the camera unit 7 to determine what kind of emotion the subject is in. For example, when a part of the patient is compressed by blood vessels for a long time during sleep, the patient's face will feel uncomfortable. After receiving the message, the main control unit will adjust the position and height of the corresponding protrusion 306 according to the patient's adjusted action, and check whether the patient is getting better. If the patient is getting better, the situation will be recorded in the storage module;

[0058] During the massage, the patient will also have different kinds of emotions and make different sounds. At this time, the microphone will record whether the patient is in too much pain, and simultaneously record the course of the patient's illness. When facing the next same patient, the raised block 306 will avoid making similar movements, and organize multiple different data through the LDA algorithm, and upload different nursing plans to the cloud database based on the wireless connection module;

[0059] Therefore, after the nursing bed 1 itself is connected to the Internet through the main control module, it can download data from the rehabilitation department or other nursing stores, and the patient can use the corresponding information when using the nursing bed. For example, the data information adjusted by the doctor according to the patient, and the information that the protrusion 306 controlled by the nursing bed 1 of the nursing store causes discomfort to the patient can all be downloaded to the local storage module. While the patient can adjust according to his or her own needs, the system will also give corresponding suggestions, and at the same time prompt the patient with information that may cause discomfort due to control, so that the patient can finally adjust to the massage method, sleep depression or the lifting height of the protrusion 306 that is suitable for him or her based on this type of basis, or directly use it in a fool-proof manner according to the loaded data, which can not only give full play to the effect of the nursing bed 1 of the present invention, but also can record the image information according to the adjustment of the patient's posture when the patient is uncomfortable, and after prediction, it will be fed back to the adjustment of the protrusion 306, so that the system can continuously optimize the best control plan based on the nursing bed 1.

[0060] The above are only preferred embodiments of the present invention, and do not limit the present invention in any form. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the above technical content without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
