[0030] Example 1, see Figure 1 , Figure 1 This is a flow chart of an embodiment of a dual-air-path control method for a lashing system provided by the present application. Figure 1 As shown, the method includes steps 101 to 103, which are specifically as follows:

[0031] Step 101: When it is detected that a human limb is placed in the cuff body bracket, the laminated airbag is inflated through the first air path, and the first airbag pressure value of the inner airbag is obtained. When it is determined that the first airbag pressure value meets the first preset airbag pressure value, a laminated airbag stop inflation signal is generated.

[0032] In one embodiment, the binding system used includes a cuff body bracket, and a laminated airbag and an inner airbag are provided in the accommodating space inside the cuff body bracket, wherein the laminated airbag is provided with an independent first air channel, and the inner airbag is provided with an independent second air channel.

[0033] Specifically, an inner ring support piece is further provided in the accommodating space inside the cuff body bracket. The inner ring support piece is placed in the middle layer, and the laminated airbag and the inner airbag are arranged in the upper and lower layers respectively.

[0034] In one embodiment, the lashing system further comprises an electrical device, wherein the electrical device comprises a micro pump valve, a four-way hose, and one or two two-way normally open solenoid valves.

[0035] Specifically, when a first two-way normally open solenoid valve is provided in the binding system, the first air route is composed of the micro pump valve, the four-way hose and the first two-way normally open solenoid valve in the binding system, wherein the micro pump valve is connected to the first two-way normally open solenoid valve through the four-way hose, and the first two-way normally open solenoid valve is connected to the laminated airbag; the second air route is composed of the micro pump valve and the four-way hose in the binding system, wherein the micro pump valve is connected to the inner layer airbag through the four-way hose.

[0036] Specifically, when a first two-way normally open solenoid valve and a second two-way normally open solenoid valve are provided in the binding system, the first air route is composed of the micro pump valve, the four-way hose and the first two-way normally open solenoid valve in the binding system; the second air route is composed of the micro pump valve, the four-way hose and the second two-way normally open solenoid valve in the binding system; wherein, the micro pump valve is respectively connected to the first two-way normally open solenoid valve and the second two-way normally open solenoid valve through the four-way hose, the first two-way normally open solenoid valve is connected to the laminated airbag, and the second two-way normally open solenoid valve is connected to the inner layer airbag.

[0037] Specifically, the laminated airbag and the inner airbag are connected to the double-way normally open electromagnetic valve and the micro pump valve in the electrical device through a single air nozzle connected to the four-way hose leading out the air path.

[0038] Specifically, the micro pump valve is an integrated pump valve, which is used to generate air and flow it into the airway to inflate the laminated airbag and the inner airbag.

[0039] In one embodiment, when only the first two-way normally open solenoid valve is provided in the binding system, when the laminated airbag is inflated through the first air path, the status of the micro pump valve and the first two-way normally open solenoid valve is detected. When it is detected that the micro pump valve is in the forward power-on state and the first two-way normally open solenoid valve is in the power-off state, the micro pump valve is controlled to inflate the laminated airbag through the first air path.

[0040] Specifically, since there is only the first two-way normally open solenoid valve, the micro pump valve is directly connected to the inner airbag through a four-way hose. Therefore, the micro pump valve inflates the laminated airbag through the first air path and also inflates the inner airbag through the second air path.

[0041] Specifically, when the operation of inflating the laminated airbag is performed through the first air path, the micro pump valve is energized in the forward direction, and the first two-way normally open solenoid valve is in the power-off state. At this time, the compressed air generated by the micro pump valve passes through the four-way hose, one way through the opened first two-way normally open solenoid valve into the laminated airbag, causing the laminated airbag to expand and achieve the binding action of the limb; and the other way will directly enter the inner airbag through the four-way hose; this is because the micro pump valve in the second air path is directly connected to the inner airbag through the four-way hose. When the micro pump valve is working and the air path is unobstructed, the gas will naturally flow into the inner airbag.

[0042] In one embodiment, when a first two-way normally open solenoid valve and a second two-way normally open solenoid valve are provided in the binding system, when the laminated airbag is inflated through the first air path, the status of the micro pump valve, the first two-way normally open solenoid valve and the second two-way normally open solenoid valve is detected. When it is detected that the micro pump valve is in the forward power-on state, the first two-way normally open solenoid valve is in the power-off state, and the second two-way normally open solenoid valve is in the power-on state, the micro pump valve is controlled to inflate the laminated airbag through the first air path.

[0043] Specifically, when the first two-way normally open solenoid valve is in a power-off state, the first gas path is in an open state; when the second two-way normally open solenoid valve is in a power-on state, the second gas path is in a closed state.

[0044] Specifically, under the configuration of two dual-way normally open solenoid valves, when inflating the laminated airbag through the first air path, it is necessary not only to ensure that the first dual-way normally open solenoid valve is in the power-off open state, but also to ensure that the second dual-way normally open solenoid valve is in the power-on closed state. In this way, the compressed air generated by the forward rotation of the micro pump valve will enter the laminated airbag through the opened first dual-way normally open solenoid valve after passing through the four-way hose, thereby inflating the laminated airbag and completing the limb binding action; and since the second dual-way normally open solenoid valve is powered on and closed, the compressed air cannot enter the inner airbag through the second dual-way normally open solenoid valve, ensuring that in the automatic binding stage, the gas only acts on the laminated airbag, avoiding premature inflation of the inner airbag and interfering with the binding effect.

[0045] Preferably, during the process of inflating the laminated airbag, the switching status of the first two-way normally open solenoid valve and / or the second two-way normally open battery valve is also detected in real time. If the first two-way normally open solenoid valve does not open normally or the second two-way normally open solenoid valve opens accidentally, the system should immediately stop the inflation operation and issue a fault prompt to prevent the equipment from malfunctioning or causing adverse effects on users due to air path errors.

[0046] In one embodiment, the electrical device further includes a pressure sensor, wherein the pressure sensor is used to identify and determine the pressure value of the inner airbag.

[0047] Specifically, the pressure sensor is connected to the four-way hose and is located between the micro pump valve and the first two-way normally open solenoid valve; when the micro pump valve is rotated forward and energized for inflation, the compressed air is diverted through the four-way hose and flows to the pressure sensor, enabling it to monitor the pressure changes in the air circuit in real time.

[0048] In one embodiment, when obtaining the first airbag pressure value of the inner airbag, the laminated airbag is inflated through the first airway. At this time, as the inflation pressure gradually increases, the laminated airbag expands and drives its small airbags to expand. Since the laminated airbag is arranged in a ring on the inner ring support sheet, the small airbags on the laminated airbag squeeze the inner ring support sheet in the binding system. The contraction of the inner ring support sheet drives the accommodating space in the cuff body bracket to become smaller. When the inner airbag is compressed to the point of squeezing into the human limbs, the pressure will be fed back to the pressure sensor. When the pressure sensor receives the feedback pressure, it uses the pressure as the first airbag pressure value of the inner airbag.

[0049] In one embodiment, the first preset airbag pressure value is a key parameter pre-set after a large number of experiments and data analysis based on actual application requirements such as ergonomics, blood pressure measurement or massage; it represents the pressure value corresponding to when the inner airbag squeezes the limb to an appropriate degree during the automatic binding process; it is used to ensure that the cuff body bracket can be stably fixed on the human limb, and will not shift during subsequent measurement or massage due to being too loose, thereby affecting the effect; nor will it cause discomfort to the user or even affect blood circulation due to being too tight; and for blood pressure measurement, appropriate binding force can make the inner airbag fit better with the limb, accurately transmit pressure changes in the blood vessels, and improve measurement accuracy; for the massage function, an appropriate initial binding state can make the massage action more effectively act on the limb.

[0050] In one embodiment, when the first airbag pressure value obtained by the pressure sensor reaches the first preset airbag pressure value, it indicates that the degree of compression of the inner airbag on the human limbs has reached a preset appropriate state. At this time, the compression of the inner ring support piece by the laminated airbag also enables the cuff body bracket to complete the effective binding of the human limbs; at this time, the pressure sensor will feed back a signal that the first airbag pressure value meets the first preset airbag pressure value to the main control unit, so that after the main control unit receives the signal, it will generate a signal to stop inflating the laminated airbag.

[0051] Step 102: When a signal for stopping the inflation of the laminate airbag is detected, the laminate airbag is stopped from being inflated, and a current function instruction of the lashing system is obtained.

[0052] In one embodiment, based on the laminate airbag inflation stop signal, the first dual-way normally open solenoid valve is controlled to be energized to cut off the compressed air supply from the micro pump valve; this prevents the micro pump valve from inflating the laminate airbag and prevents the cuff body bracket from being tied too tightly.

[0053] In one embodiment, the user can issue functional instructions through the operation interface on the banding system; wherein, the operation interface can be a physical button, such as a blood pressure measurement button, a massage button, etc., and the user presses the corresponding button, and the banding system can obtain the corresponding functional instruction; or it can be a touch screen display, and the user clicks the corresponding icon on the screen to select the blood pressure measurement or massage function; for more intelligent banding systems, voice commands may also be supported. The user can say voice commands such as "start blood pressure measurement" or "start massage", and the device's voice recognition system will recognize and convert them into functional instructions.

[0054] Preferably, taking a physical button as an example, when the user presses the blood pressure measurement button, the blood pressure measurement button will trigger an electrical signal, which is transmitted to the main control chip through the circuit inside the binding system. After receiving the electrical signal, the main control chip decodes and identifies the electrical signal, thereby obtaining the current function instruction as a blood pressure measurement instruction; taking a touch display screen as an example, when the user clicks on the blood pressure measurement icon, the touch sensing layer of the display screen detects the touch action and converts the position information into an electrical signal and transmits it to the main control chip. The main control chip parses the signal according to a preset program to determine the current function instruction; the voice instruction is collected by the microphone, and after processing by the voice recognition module, the recognition result is sent to the main control chip to complete the acquisition of the function instruction.

[0055] Step 103: When the current function instruction is a blood pressure measurement instruction, the inner airbag is inflated through the second air path, and the second airbag pressure value of the inner airbag and the pulse fluctuation value of the human limb are obtained. When it is determined that the second airbag pressure value and the pulse fluctuation value meet the preset blood pressure measurement requirements, the laminated airbag and the inner airbag are deflated respectively.

[0056] In one embodiment, when only the first two-way normally open solenoid valve is provided in the binding system, when the inner airbag is inflated through the second air path, the status of the micro pump valve and the first two-way normally open solenoid valve is detected. When it is detected that the micro pump valve is in the forward power-on state and the first two-way normally open solenoid valve is in the power-on state, the micro pump valve is controlled to inflate the inner airbag through the second air path.

[0057] In one embodiment, when a first two-way normally open solenoid valve and a second two-way normally open solenoid valve are provided in the binding system, when the inner airbag is inflated through the second air path, the status of the micro pump valve, the first two-way normally open solenoid valve and the second two-way normally open solenoid valve is detected. When it is detected that the micro pump valve is in the forward power-on state, the first two-way normally open solenoid valve is in the power-on state, and the second two-way normally open solenoid valve is in the disconnected state, the micro pump valve is controlled to inflate the inner airbag through the second air path.

[0058] In one embodiment, blood pressure measurement primarily detects the pressure changes exerted by blood flow within arterial vessels on the vessel walls. Under normal circumstances, arteries pulsate regularly as the heart contracts and relaxes. This pulsation can be detected on the surface of the limb and manifests as pulse fluctuations. When the inner balloon is inflated and applies pressure to the limb, it gradually affects blood flow in the arteries. When the pressure reaches a certain level, the artery is completely blocked, and the pulse fluctuation value becomes zero. This pressure value is closely related to the body's blood pressure. By monitoring the pulse fluctuation value and the balloon pressure value, blood pressure parameters such as systolic and diastolic pressure can be calculated.

[0059] In one embodiment, when the micro pump valve inflates the inner airbag through the second air path, the pulse fluctuation value of the human limb during the inflation process of the inner airbag is obtained in real time. When the pulse fluctuation value is detected to be 0, the second airbag pressure value of the inner airbag is obtained in real time; if the second airbag pressure value does not meet the preset blood pressure measurement airbag pressure value, the inner airbag is continuously inflated until the second airbag pressure value meets the preset blood pressure measurement airbag pressure value, and the inflation process of the inner airbag is stopped, and it is determined that the current second airbag pressure value and the pulse fluctuation value meet the preset blood pressure measurement requirements.

[0060] Specifically, the electrical device is further provided with a pulse sensor, wherein the pulse sensor is used to monitor the pulse fluctuation value of the human limbs in real time.

[0061] Specifically, while the micropump valve inflates the inner balloon through the second airway, the system simultaneously activates the pulse sensor to monitor the pulse fluctuation value of the human limb in real time, and the pressure sensor to obtain the second balloon pressure value of the inner balloon in real time. As the inner balloon pressure continues to increase, when the pressure reaches a level sufficient to completely block arterial blood flow, the pulse fluctuation value drops to 0. At this point, the system immediately records the current second balloon pressure value of the inner balloon. The preset blood pressure measurement balloon pressure value is a range determined based on extensive medical research and clinical practice, and is generally higher than the highest possible systolic blood pressure in the human body. If the recorded second balloon pressure value does not meet the preset blood pressure measurement balloon pressure value, it indicates that the current inflation pressure is insufficient and accurate blood pressure measurement may be inaccurate. At this point, the system controls the micropump valve to continue inflating the inner balloon, causing the inner balloon pressure to continue to increase. When the second balloon pressure value rises to meet the preset blood pressure measurement balloon pressure value, it is considered that the appropriate pressure conditions for accurate blood pressure measurement have been established, that is, the current second balloon pressure value and pulse fluctuation value (0) meet the preset blood pressure measurement requirements.

[0062] In one embodiment, when it is determined that the second airbag pressure value and the pulse fluctuation value meet the preset blood pressure measurement requirements, the inflation of the inner airbag is also stopped; specifically, the generation of compressed gas is stopped by controlling the micropump valve, or the second dual-way normally open battery valve is controlled to be in a powered closed state.

[0063] In this embodiment, by real-time monitoring of pulse fluctuations and the secondary airbag pressure, and dynamically adjusting the inflation process based on changes in both, appropriate pressure conditions can be achieved during measurement, avoiding inaccurate measurement results due to under-inflation or over-inflation. For example, if under-inflation prevents complete blockage of the blood vessels, accurate systolic pressure readings will be impossible; over-inflation may cause discomfort to the limb and even affect measurement accuracy.

[0064] In one embodiment, the laminate airbag and the inner airbag are subjected to exhaust processing, specifically including: exhausting the inner airbag at a first exhaust time, and exhausting the laminate airbag at a second exhaust time, wherein there is a preset time difference between the first exhaust time and the second exhaust time.

[0065] Specifically, when the binding system has only one two-way normally open solenoid valve, the micro pump valve is controlled to reverse and open the air circuit for exhaust. At this time, since the first two-way normally open solenoid valve is in the power-on closed state, the inner airbag is first exhausted based on the four-way hose in the second air circuit, and after the preset time difference of the first exhaust moment of the inner airbag, the first two-way normally open battery valve is controlled to be adjusted to the power-off open state. At this time, the laminated airbag is also exhausted based on the four-way hose in the first air circuit; until the laminated airbag and the inner airbag are exhausted.

[0066] Specifically, when the binding system is equipped with both a first two-way normally open solenoid valve and a second two-way normally open solenoid valve, the micro pump valve is controlled to reverse and open the air path for exhaust. At this time, the first two-way normally open solenoid valve and the second two-way normally open solenoid valve are in the powered-on closed state. Therefore, the second two-way normally open battery valve is first controlled to be adjusted to the powered-off open state, and the inner layer airbag is scheduled based on the four-way hose in the second air path. After a preset time difference from the first exhaust moment of exhausting the inner layer airbag, the first two-way normally open battery valve is controlled to be adjusted to the powered-off open state, and the laminated airbag is exhausted based on the four-way hose in the first air path; until the laminated airbag and the inner layer airbag are exhausted.

[0067] In one embodiment, when the current function instruction is a massage instruction, the inner airbag is inflated through the second air path, and the first real-time airbag pressure value of the inner airbag during the inflation process is obtained. When the first real-time airbag pressure value meets the second preset airbag pressure value, the inner airbag is deflated.

[0068] Specifically, when the current function instruction is a massage instruction, the process of inflating the inner layer airbag through the second air path is the same as the process of inflating the inner layer airbag through the second air path when the current function instruction is a blood pressure measurement instruction, and will not be described in detail here.

[0069] Specifically, during the process of inflating the inner airbag, the first real-time airbag pressure value of the inner airbag is continuously obtained through the pressure sensor, and the first real-time airbag pressure value is fed back to the main controller, so that the main controller can accurately grasp the pressure state of the inner airbag.

[0070] Specifically, the second preset airbag pressure value is a key parameter pre-set based on factors such as the massage intensity requirement, comfort requirements, and human physiological characteristics; it indicates the pressure value corresponding to when the inner airbag reaches the appropriate massage pressure during the massage process; when the first real-time airbag pressure value reaches the second preset airbag pressure value, it indicates that the inner airbag has been inflated to the appropriate massage pressure. At this time, the pressure of the inner airbag on the limbs can produce the expected massage effect, such as squeezing and relaxing muscles.

[0071] Specifically, when the first real-time airbag pressure value meets the second preset airbag pressure value, the inner airbag is exhausted by controlling the micro pump valve to reverse or opening the second dual-way constant solenoid valve, so that the gas in the inner airbag is exhausted and the pressure gradually decreases.

[0072] Specifically, the exhaust treatment of the inner airbag is, on the one hand, to allow the limbs to relax briefly and avoid discomfort caused by long-term pressure; on the other hand, it is to control the massage rhythm and cooperate with the subsequent re-inflation operation to form a rhythmic massage action.

[0073] In one embodiment, a second real-time airbag pressure value of the inner airbag during the deflation process is obtained. When the second real-time airbag pressure value drops to a preset third preset airbag pressure value, the inner airbag is inflated again through the second air path until it is detected that the number of inflation and deflation of the inner airbag meets a preset number threshold, and the laminated airbag and the inner airbag are deflated respectively.

[0074] Specifically, the third preset airbag pressure value is a pre-set key parameter, which represents a suitable low-pressure state reached by the inner airbag during the deflation process; when the second real-time airbag pressure value drops to this preset value, it means that the pressure of the inner airbag on the limb has been reduced to a certain level, and the limb has been properly relaxed.

[0075] Specifically, when the second real-time airbag pressure value drops to the preset third preset airbag pressure value, the inner airbag is re-inflated through the second air path, allowing the inner airbag to expand again and exert pressure on the human limbs. This process simulates the squeezing and relaxing movements during human hand massage, giving users a comfortable massage experience.

[0076] Specifically, the preset number threshold is pre-set according to the massage effect and the human body's tolerance; by controlling the number of inflation and deflation, the duration and intensity of the massage can be accurately controlled; when the number of inflation and deflation reaches the preset number threshold, it means that the massage has been carried out for a sufficient period of time and has achieved the expected massage effect; that is, by continuously repeating the inflation and deflation process, according to the preset inflation and deflation threshold, massage effects of different modes and intensities can be achieved to meet the user's diverse massage needs.

[0077] Specifically, when it is detected that the number of times the inner airbag is inflated and deflated meets the preset threshold, the process of venting the laminated airbag and the inner airbag is the same as the process of venting the laminated airbag and the inner airbag after the blood pressure measurement is completed, and will not be described in detail here.
