[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 below with reference to the accompanying drawings:

[0036] Example:

[0037] The present invention provides an electric rehabilitation nursing bed, comprising a nursing bed 1 and a support mechanism 101, a load-bearing frame 102 is installed between the nursing bed 1 and the support 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, such as Figure 1 The lifting and electrically movable device provided at the supporting mechanism 101 can meet the needs of different functions.

[0038] Furthermore, a bed plate 2 is provided at the top of the fixed frame 103, and a strip unit 3 is provided on the inner side of the bed plate 2. 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. The strip unit 3 includes a flexible layer (301) and a travel layer (302) located below the flexible layer (301), wherein:

[0039] The flexible layer 301 includes fixed ends 303 for installation at both ends, 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. 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 set, and the installed travel layer 302 can be fixed at a certain position of the sliding groove 305 after the internal protrusion block 306 moves back and forth, or repeatedly performs reciprocating motion. This method can lift the upper flexible layer 301 so that the bedding is forced upward, allowing the patient's target area to move according to the action of the equipment or be reversely clamped by different protrusion blocks in 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 upward-lifting 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 bar 308 is provided on the middle side of the bottom end of the elastic part 304, and the position of the blocking bar 308 is 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 bar 308 provided can also reduce the force area of ​​the elastic part 304 on the basis of rising, and the increased The added electric telescopic rod 307 can also make the upward-lifting structure possible. It can also allow multiple bed panels 2 to be combined into different shapes, allowing patients to lie in them, fixing their position or preventing them from falling off the bed. The multiple raised blocks 306 can also be combined front and back into a left-right staggered structure with a slope. After placing a pillow on the surface, the patient's legs can be raised to a certain height, which not only fixes the position of the pillow but also allows the angle of the slope to be adjusted 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 stroke 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 stroke 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, an air hole 401 is penetrated through the top surface of the breathable layer 4, and a slot 402 is provided at the edge of the air hole 401, and the slot 402 is used to connect the breathable grid 310, and 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 in the inner side of the bed plate 2, and 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 a slot is left. 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, an air pump unit and a pipe filter;

[0045] like Figure 4 、 6 As shown in FIG7 , since bedsores are mainly caused by the pressure of the body, shear force and friction on the skin surface, and the moisture of the skin, the above structure only solves the problem related to pressure. As for the moisture of the bedding and the skin, the thrust generated by the electric telescopic rod 307 is used to generate air circulation. This is sufficient for normal sleeping conditions. However, for patients who are bedridden for a long time, bedsores may still occur. Even if the bed sheets are changed frequently and the patient turns over frequently, the skin will still be moist. Therefore, a breathable layer 4 structure is further designed. Since the bed plate 2 is a block structure, it moves as a unit of the bed plate 2. Therefore, the air pump device 5 is embedded and fixed to each bed plate 2 during the design.

[0046] like Figure 2 、 7 As shown, the symmetrical air pump device 5 will draw the air in from the air outlet through the internal air duct structure, through the pipe filter and the heating module, and 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 breathable layer 4 connected to the ventilation pipe 403, the air will flow upward from the air hole 401 and upward from the breathable 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 be opened to blow the hot air upward to the bedding, thereby increasing the air circulation of the bedding and reducing the humidity of the bedding, and also keeping the patient's skin in the quilt in a dry state at all times; 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 circulate upward from the gap between the strip units 3. This method can increase the upward air pressure and reduce the humidity in the bedding. Combined with the above structure, the probability of patients developing bedsores 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 configuration is completed, 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 based on the last time the patient left the bed as recorded in the storage module.

[0048] Then, the pressure sensor 6 compares the weight of the bedding on the bed plate 2 after the patient's use with the weight of the bedding on the bed plate 2 after the last treatment. If 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 large extent, so that the temperature and wind speed can rise to a state of rapid drying, so that the higher 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 time.

[0049] The fixed frame 103 is composed of two or more 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 is provided. The nursing bed 1 includes a movable support mechanism 101, a fixed frame 103, a bed body panel 2, a headboard, and a footboard, which are respectively used to carry a camera unit 7, a main control unit, an air pump device 5, and a bar unit 3, 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 pipe filter. The heating module includes a temperature sensing unit, which is used by 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 upper and lower parts of the strip unit 3.

[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 shoot 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 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. Under 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 for patients with different injuries or illnesses, the camera unit 7 can capture corresponding facial information, that is, the convex shape of the bed plate 2 can be automatically adjusted to different patients, so that rehabilitation workers can perform rehabilitation physiotherapy and rehabilitation massage 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. It can analyze the patient's facial expression based on the image captured by the camera unit 7 to determine the patient's mood. For example, when a part of the patient's face is compressed for a long time during sleep, the patient will feel uncomfortable on the face. After receiving the information, the main control unit will adjust the position and height of the corresponding protrusion 306 according to the patient's adjusted movements to 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 emotions and make different sounds. At this time, the microphone will record whether the patient is in too much pain. At the same time, it will record the patient's disease progression. When facing the next patient, the raised block 306 will avoid making similar movements. The multiple different data are sorted through the LDA algorithm, and different care plans are also uploaded to the cloud database through 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 shops, 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 shop 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 remind the patient of information that may cause discomfort due to control, so that the patient can finally adjust to the massage method, sleeping depression or raising height of the protrusion 306 that is suitable for him or her based on such basis, or directly use it in a fool-proof manner according to the loaded data. Not only can the effect of the nursing bed 1 of the present invention be brought into play, but also when the patient is uncomfortable, the image information can be recorded and predicted according to the adjustment of the patient's posture, and then 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 are not intended to limit the present invention in any form. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, use the above technical content to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any changes, modifications, equivalent changes and modifications made to the above embodiments based on the technology of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the present technical solution.
