DETAILED DESCRIPTION
[0017] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0018] Before describing the solution of the present application, the following is an introduction on how the massage air cushion body is placed on the bed in the solution of the present application. The placement component structure for placing the massage air cushion body includes a long tube, a sleeve, a fixing ring, a fixing ring lifting airbag, an air compressor, etc. The long tube and the sleeve form a fixing ring, wherein the sleeve and the venue form a fixing ring such as Figure 1 shown.
[0019] Among them, the fixing ring is used to fix the bed sheet. It is first put on the patient's bed, and then the two sides of the bed sheet are fixed. After fixation, it can be inflated and lifted, so that the patient can be lifted a certain distance, and then the massage air cushion can be put in, and it is also convenient to replace the patient's bed sheet; the long tube is used to form a circle and fix the bed sheet on it; the sleeve is used to merge the two long tubes together; the fixing ring lifting airbag is used to lift the fixing ring. The reason for using the airbag here is that it is light. If a hydraulic structure or motor is used, it will increase the weight and is not conducive to single-person operation. The trapezoidal airbag is not only easy to install, but also has a better fixing effect. The diagram of the fixing ring lifting airbag lifting the patient and the bed sheet is as shown in the figure Figure 2 As shown; air compressor is used to provide high-pressure gas.
[0020] The specific placement process is: when in use, first place the two long tubes on both sides of the patient, then connect them with sleeves and then fix the sheets on the long tubes, and then place the fixed ring lifting airbags under the tubes at the upper and lower ends of the mattress. When the two fixed ring lifting airbags are inflated, the human body will be lifted to a certain height by the sheets through the fixed rings. At this time, the caregiver can place the massage cushion directly under the patient. If the massage cushion is too long near the head and feet and is difficult to place, you can roll up part of the two ends of the massage airbags and place them. Then, the caregiver can deflate the fixed ring lifting airbags. After deflation, you can take away the fixed ring lifting airbags, untie the sheets and disassemble the fixed ring.
[0021] In addition, it should be noted that the placement component can not only be used to assist the caregiver in placing the massage air cushion, but also to assist the caregiver in changing the bed sheets. Specifically, after the patient is lifted up by the lifting airbag, a new bed sheet is replaced. When the patient is put down, there are both a new and an old bed sheet under the patient. At this time, the caregiver only needs to pull out the old bed sheet. Specifically, Figure 3 A schematic diagram of a massage air cushion provided in an embodiment of the present application.
[0022] like Figure 3 As shown, the massage air cushion 10 includes: a massage air cushion body 11, a nozzle 12, a sensor 13 and a controller 14.
[0023] Among them, an airbag is arranged on the massage air cushion body 11; there are multiple nozzles 12, which are arranged on the side of the massage air cushion body and are used to diffuse the gas into the airbag in a targeted form; there are multiple sensors 13, which are used to monitor the air pressure value of the gas in the airbag and perform air pressure sampling on the gas in the airbag; the controller is used to generate a target massage instruction according to the user's target needs and the air pressure sampling data, and control the corresponding nozzle 12 to perform the target action according to the target massage instruction, so as to change the shape and / or pressure of any plane coordinate position of the airbag to complete the massage of the user.
[0024] It can be understood that the embodiment of the present application constructs a massage air cushion 10, including a massage air cushion body 11, a nozzle 12, a sensor 13 and a controller 14, wherein an air bag is provided on the body 11 of the massage air cushion, and the nozzle 12 is responsible for diffusing the gas into the air bag in a targeted form, such as slow or accelerated, to meet the needs of different massage modes or massage strengths, and the sensor 13 is used to monitor the air pressure changes in the air bag and perform air pressure sampling so as to be able to respond to the air pressure changes in a timely manner to ensure that the pressure of the air bag is always maintained in the optimal state. The controller 14 generates accurate target massage instructions based on the user's target needs and the air pressure sampling data, and generates accurate target massage instructions according to the target needs of the user and the air pressure sampling data. The target massage instruction controls the corresponding nozzle 12 to perform the target action to change the shape, pressure distribution, etc. of the specific plane coordinate position of the airbag to form different pressures on the user, thereby completing the massage of the user. The massage air cushion of the present application can realize automatic massage, and the massage area includes all areas covered by the massage air cushion body, that is, the shape, pressure distribution, etc. of any plane coordinate position of any airbag can be changed. The coverage range is large, and the entire back, legs and head of the user can be covered at one time, and the massage accuracy or massage mode can be adjusted according to user needs, thereby enhancing the user's experience of using the massage air cushion and the comfort of massage.
[0025] The massage instructions of the embodiment of the present application may include massage accuracy, massage area, massage mode, massage cycle, massage frequency, action time and sequence of each nozzle, etc.; the target action may include the time of ejecting gas and ejecting gas in the target form; the sensor 13 can also be used to calculate the airflow pressure diffusion speed and diffusion value of each jet nozzle under the current air pressure; there are many sets of development boards that can be used for the controller, for example, the Nucleo STM32F401 basic development board can be directly packaged into a controller, or a better development board such as the ESP32-S2 Kaluga kit with a screen can be used. These development boards can directly output control signals to the wireless control relay described below via WIFI, and can also directly output control signals through the TX port, and have good compatibility. The position layout of the sensor 13 is shown in the figure below Figure 4 As shown; the plane is the upper plane of the massage air cushion body, and the length and width of the massage air cushion body are divided into horizontal and vertical axes, and a plane coordinate system is constructed with an angle as the origin.
[0026] It should be noted that, in the embodiment of the present application, the user who issues the target massage demand may be a medical staff or the patient himself, and the user being massaged is the patient himself.
[0027] In the embodiment of the present application, types of the nozzle 12 include a Laval nozzle and a vortex nozzle.
[0028] The structure of the Laval nozzle in the embodiment of the present application is as follows Figure 5As shown, it is used to diffuse the gas into the airbag in an accelerated form.
[0029] Among them, the Laval nozzle can significantly increase the flow speed of the gas and generate rapid pressure waves through special geometric design (such as convergence-expansion pipe).
[0030] The structure of the vortex nozzle in the embodiment of the present application is as follows Figure 6 As shown, a teardrop-shaped conductor is also provided at the throat thereof for diffusing the gas into the airbag in a slow form.
[0031] Specifically, the vortex nozzle is used to generate a slower vortex, which can generate slow air movement energy to massage the patient. In addition, a teardrop-shaped guide body is added to the throat of the vortex nozzle to diffuse the incoming airflow, thereby forming a stable relatively slow vortex group that is released to ensure uniform distribution of the airflow in the airbag and provide a more delicate and smooth massage effect. This speed is designed for the high-speed airflow speed and high energy concentration of the anti-Laval nozzle.
[0032] In the embodiment of the present application, the massage air cushion 10 of the embodiment of the present application further includes: a plurality of solenoid valves connected to the plurality of nozzles, for controlling the flow of gas in the nozzles.
[0033] For example, the A solenoid valve is connected to the A nozzle, and the B solenoid valve is connected to the B nozzle. When the A solenoid valve is closed and the B solenoid valve is closed, it means that the gas can only flow into the airbag from the B nozzle, but cannot flow in from the A nozzle.
[0034] In the embodiment of the present application, the massage air cushion 10 of the embodiment of the present application also includes: a wireless relay.
[0035] Among them, the wireless relay is used to control the corresponding solenoid valve to open or close according to the target massage instruction.
[0036] It can be understood that after generating the target massage instruction, the controller 14 of the massage air cushion 10 of the embodiment of the present application can send the target massage instruction to the wireless relay. The wireless relay can control the corresponding solenoid valve to open or close according to the target massage instruction, thereby controlling the flow path of the gas, thereby meeting the needs of different massage intensities, massage areas, massage modes, etc.
[0037] In the embodiment of the present application, the massage air cushion 10 of the embodiment of the present application also includes: an exhaust valve arranged on the side of the massage air cushion body, which is used to discharge part of the gas when the gas pressure value is greater than or equal to the preset pressure value until the gas pressure value is less than the preset pressure value.
[0038] Among them, the preset air pressure value can be set according to the specific situation and is a safe air pressure upper limit, and there is no specific limitation on this.
[0039] It can be understood that the massage air cushion body 11 of the embodiment of the present application is also provided with an exhaust valve, which is used to exhaust part of the gas when the gas pressure value is greater than or equal to the preset gas pressure value, until the gas pressure value is less than the preset gas pressure value, to ensure that the gas pressure in the airbag is kept within a safe range, to prevent damage to the massage air cushion body or discomfort to the user during massage due to excessive gas pressure, wherein the exhaust valve is arranged as shown in FIG. Figure 4 shown.
[0040] In an embodiment of the present application, the controller 14 is further used to: determine at least one of a target massage mode, a target massage accuracy, and a target massage area according to the user's target needs; determine a target massage algorithm according to the target massage mode; generate a target massage instruction according to the target massage algorithm, the target massage accuracy, at least one of the target massage area, and the air pressure sampling data.
[0041] Among them, massage modes can include tapping mode, kneading mode, patting mode, etc.; massage accuracy Z includes Z1 and Z2, which determines the delicacy and effect of massage. A higher Z value can make the massage more delicate and simulate an effect closer to manual technique. Otherwise, the massage will be rougher and suitable for simple relaxation scenes.
[0042] It can be understood that the embodiments of the present application can determine at least one of the target massage mode, target accuracy and target massage area according to the user's target needs, select the target massage algorithm according to the target massage mode, and generate target massage instructions based on the target massage algorithm, target massage accuracy, at least one of the target massage area, and air pressure sampling data.
[0043] Specifically, if the user selects the target massage accuracy and the target massage mode, the whole body is massaged by default, and the target massage instructions are generated according to the target massage accuracy, the target massage mode and the air pressure sampling data; if the user selects the target massage accuracy and the target massage area, the target massage area is massaged with the default massage mode and the target massage accuracy, and the target massage instructions are generated according to the target massage accuracy, the target massage area and the air pressure sampling data; if the user selects the target massage mode and the target massage area, the target massage area is massaged with the default accuracy of the target massage mode, and the target massage instructions are generated according to the target massage mode, the target massage area and the air pressure sampling data.
[0044] In the embodiment of the present application, the massage air cushion 10 of the embodiment of the present application also includes an air compressor.
[0045] The air compressor is connected to a plurality of nozzles 12 via pipelines for producing gas.
[0046] It should be noted that the motor of the air compressor in the massage air cushion 10 of the present application is directly connected to the mains, and the wireless relay controls the mains current to control the on-off of the solenoid valve. The specific signal direction is as follows: Figure 7 shown.
[0047] In addition, it should be noted that the massage air cushion 10 of the embodiment of the present application also includes a sub-air storage pipe located at Figure 5 The right half of the Laval nozzle is used to store a certain amount of air. The Laval nozzle can accelerate the outflow of air. If there is excess gas outflow, better results can be achieved. However, the flow rate of high-pressure air through a thin pipe is not as fast as that of a thick pipe. If a thick pipe is used, the cost and weight of the entire equipment will increase, which is not conducive to installation and use.
[0048] Specifically, the massage air cushion of the present application and its working principle are described below through a specific embodiment. The structure of the complete massage air cushion is as follows: Figure 8 As shown, it includes a wireless relay, a controller, a sensor, a massage air cushion body, an exhaust valve, a nozzle, a solenoid valve, an air compressor, etc. After the massage air cushion body is inflated, Fig. 9 As shown, the data line connection and signal direction of the electronic components are as follows Fig.10 shown.
[0049] The working principle of the massage air cushion is to release the air in the air cushion in a shock wave-like manner, which can form a superimposed pressure area at the corresponding point. By superimposing the fan-shaped waves formed by the gas shock waves in the two layers of airbags, a pressure peak and valley area can be formed in any area of the airbag, so that pressure massage can be performed. This can be achieved by controlling the solenoid valve through the vertical and horizontal control circuit. Among them, the pre-step of using the massage air cushion for massage is to lift the patient with the assistance of the lifting airbag and then place the massage air cushion.
[0050] Taking the tapping mode as an example, the algorithm of each massage mode can be performed through time calculation.
[0051] The calculation formula for the tapping mode of each part is {Tn*Tx / Z1}, {Fn*Fx / Z2}, where 0≤Tn≤Z1, 0≤Fn≤Z2. Tx and Fx are the air pressure transmission time samples received by the sensor, that is, the air pressure change time sampling data. Tx represents the horizontal axis sampling calculation value, which indicates the time sampling value of the gas propagating along the horizontal axis, and is used to calculate the speed and path of the gas propagating horizontally in the airbag to ensure that the pressure change of the airbag meets expectations. Fx represents the vertical axis sampling calculation value, which indicates the time sampling value of the gas propagating along the vertical axis, and is used to calculate the speed and path of the gas propagating longitudinally in the airbag to ensure that the pressure change of each airbag meets expectations. Among them, the vertical axis and the horizontal axis represent the length and width of the airbag on different horizontal planes, that is, the coordinate system based on the airbag plane. By measuring Tx and Fx, a relatively accurate air pressure diffusion model in the airbag can be generated. For example, in a Laval nozzle, the gas flows rapidly to form a spike or circular wave crest, while in a vortex nozzle, the gas forms a stable vortex ring and remains unspread over a long distance. Based on the time difference between Tx and Fx, the pressure distribution in the airbag is calculated to ensure the consistency and comfort of the massage process.
[0052] (Z1, Z2)∈N+ is the number of times the sampling time can be divided. The larger the number, the denser the crossover position at the output. In order to facilitate sampling accuracy, this application uses three sensors for right-angle triangle positioning. By using the time difference received after each nozzle is released separately as the unit of length, a relatively accurate air pressure diffusion model in the airbag can be generated, such as Fig.11 As shown, Fig.11 It is a pressure wave superposition diffusion model for Laval nozzle.
[0053] It should be noted that the actual pressure fluctuations in the entire airbag are more complex. If you want to make better use of the peak superposition effect, more calculations are required, but here all you need is the simplest principle, peak superposition and trough cancellation. Each nozzle at each point can participate or not, which means that more nozzles participating can get more peak superposition pressure.
[0054] Unlike the Laval nozzle, which can generate sharp peaks and circular crests, the vortex ring generated by the circular vortex nozzle is more stable. Fig.12 It is the vortex ring motion path, which can remain non-diffusion for a long distance, and combined with the Laval nozzle can form a specific massage effect, such as scraping effect.
[0055] Specifically, if Fig.13 As shown, in this embodiment, after the user issues a massage instruction, the wireless relay and the controller process storage are called to achieve massage for the user. The specific controller control process is as follows Fig.14As shown, by sampling sensor data and manually inputting precision Z value, by selecting massage method algorithm, calculating output, the output is the relay circuit control signal of the time interval, among which the massage algorithm traversal process is as follows Fig.15 As shown, specifically: The left side is the loop output of the horizontal axis. When a Tn time calculation is output, a Tn value +1 is returned until Tn equals Z1. The right side is the loop output of the vertical axis. When an Fn calculation is output, the Fn value +1 is returned until Fn = Z2. There is also a judgment here, that is, whether Fn cycles for a cycle. If it is less than a cycle, the Tn time calculation value is not +1. When Fn cycles for a cycle, the Tn time calculation is +1. Fig.15 As shown, the points on the air cushion are traversed along the vertical axis. After each vertical axis is traversed, the next vertical axis point is moved. If you want to traverse the horizontal axis, the value of the cycle period judgment is switched to Tn.
[0056] Fig.16 This is the Fx time calculation principle of a Laval nozzle, which is to calculate the sides of a right triangle, Fx = , the time calculation of each nozzle at each point can be obtained through the original sampling, where, express Fig.16 The horizontal axis is the square of the time length, It represents the square of the time length of the vertical axis, and Fx is the actual nozzle gas diffusion time, that is, the function solution required for the position where the nozzle gas peaks of the vertical axis and the horizontal axis are to cross and overlap in the figure.
[0057] In addition, the above data can also be directly controlled and output through visual control using a mobile phone or tablet, such as Fig.17 As shown in Figure 2, when the time position data of each point is visualized, the corresponding point information is as follows: Fig.17 As shown, when the nurse taps the circular area in the figure above, it is equivalent to outputting several points in this area at the same time to form a superimposed air pressure area. At this time, the controller arranges and sends the vertical and horizontal axis output signals of all nozzles in the corresponding area to ensure that the air pressure peaks can form a correct superposition in this area.
[0058] In addition, it should be noted that the massage principle of the embodiment of the present application can be understood by observing the interference of water waves. And this principle can also be used for massage by using water. Compared with air, the ripple energy conduction efficiency of water is higher, but there are also some problems, that is, the specific heat capacity of water is higher, it needs to be heated for a long time, and the cost of use is high. Compared with the air contact device, the air pump can be placed outside the ICU. The water cushion requires a relatively powerful electromagnetic wave generator to be placed inside. Compared with the air contact device, the safety inspection interval is greatly shortened. Correspondingly, the air cushion can be used until it cannot be used. It only needs to be inspected when it cannot be used. Usually, it only needs to replace the air filter element. Even if there is a small hole in the air cushion that leaks slightly, it will not affect the use, but the water cushion needs to be checked regularly for circuit leakage and water leakage. There must not be any leakage and leakage. And compared with air, the wave conduction speed of water is also relatively slow, and the massage effect of rapid vibration cannot be achieved, and the reflectivity is high, which will reduce the massage effect of the massage point. When performing precise positioning massage, a wave absorber is required. Compared with the massage air cushions on the market, the massage air cushion of the present application can massage the entire area covered by the air cushion. All positions of the patient's back can be massaged at once, the massage intensity is adjustable, and a variety of massage techniques can be simulated.
[0059] According to the massage air cushion proposed in the embodiment of the present application, it includes a massage air cushion body, a nozzle, a sensor and a controller, wherein an airbag is arranged on the body of the massage air cushion, and the nozzle is responsible for diffusing the gas into the airbag in a targeted form, such as slow or accelerated, to meet the requirements of different massage modes or massage strengths, and the sensor is used to monitor the air pressure changes in the airbag and perform air pressure sampling so as to be able to respond to the air pressure changes in a timely manner to ensure that the pressure of the airbag is always maintained in an optimal state. The controller generates accurate target massage instructions based on the user's target requirements and the air pressure sampling data, and controls the corresponding nozzle to perform the target action according to the target massage instructions to change the shape, pressure distribution, etc. of the specific plane coordinate position of the airbag to form different pressures on the user, thereby completing the massage of the user, and the massage air cushion of the present application can realize automatic massage, and the massage area includes all areas covered by the massage air cushion body, with a large coverage range, which can cover the entire back, legs and head of the user at one time, and can adjust the massage accuracy or massage mode, etc. according to user needs, thereby improving the user's experience of using the massage air cushion and the comfort of massage. Next, the control method of the massage air cushion proposed in the embodiment of the present application is described with reference to the accompanying drawings.
[0060] Fig.18 It is a flow chart of the control method of the massage air cushion according to the embodiment of the present application.
[0061] like Fig.18 As shown, the control method of the massage air cushion is used to control the above-mentioned massage air cushion, comprising the following steps: In step S101, the air pressure sampling data of the sensor is obtained.
[0062] In step S102, a target massage instruction is generated according to the user's target demand and the air pressure sampling data.
[0063] It can be understood that the embodiments of the present application can determine at least one of the target massage mode, target massage accuracy and target massage area according to the user's target needs; determine the target massage algorithm according to the target massage mode; generate target massage instructions according to the target massage algorithm, target massage accuracy, at least one of the target massage area, and air pressure sampling data, so as to meet the massage needs of different users and enhance the user experience.
[0064] In step S103, the corresponding nozzle is controlled to perform the target action according to the target massage instruction to change the shape and / or pressure of the airbag at any plane coordinate position to complete the massage for the user.
