Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples.

[0030] The present application provides a limb massage device for monitoring pulse. Figure 1 As shown, it is an axonometric schematic diagram of the limb massage device for monitoring pulse of the present application, and the limb massage device for monitoring pulse includes:

[0031] A cuff 1, wherein the cuff 1 is provided with a double-chamber airbag 2 surrounding a human limb;

[0032] A control host 3 connected to the cuff, the control host 3 comprising a control unit, a drive unit and a monitoring unit, the control unit being communicatively connected to the drive unit and the monitoring unit respectively;

[0033] The control unit is used to control the driving unit to inflate the double-chamber airbag to massage the limb;

[0034] The monitoring unit is used to monitor the pressure value of the dual-chamber airbag and the pulse fluctuation signal of the human body and feed back to the control unit;

[0035] The control unit is further used to determine whether to stop controlling the driving unit to inflate the dual-chamber airbag according to the pressure value and the fluctuation signal fed back by the monitoring unit.

[0036] In this embodiment, the cuff 1 is provided with a receiving space for a human limb (for example, an upper limb) to be inserted, and the dual-chamber airbag 2 surrounds the receiving space. When the user needs to use the massage device, the upper limb is inserted into the receiving space and the dual-chamber airbag 2 is wrapped around the upper limb part to be massaged, and then the massage device is positioned using the positioning mechanism. The massage device also includes a control host 3 connected to the cuff through a plurality of air nozzle joints. The control host 3 includes a control unit, a driving unit, and a monitoring unit. The control unit is respectively connected to the driving unit and the monitoring unit for communication. The control unit can be a microcontroller unit (MCU), the driving unit can be a micro air pump, and the monitoring unit can be a pressure sensor. The control unit is used to control the driving unit to inflate the dual-chamber airbag 2. When the dual-chamber airbag 2 is inflated, the air pressure is transmitted from the dual-chamber airbag 2 to the human limb, thereby achieving massage of the limb.

[0037] During the massage process, the blood flow of the limbs will be blocked, causing the limbs to feel numb and may cause inconvenience in limb movement. At this time, if the user is unwell, it may be difficult to stop the massage by manually turning off the power of the massage device. For this reason, the present application uses a monitoring unit to monitor the pressure value of the dual-chamber airbag and feed it back to the control unit, and monitors the fluctuation signal of the human pulse and feeds it back to the control unit. The control unit determines whether to stop controlling the driving unit to inflate the dual-chamber airbag according to the pressure value and fluctuation signal fed back by the monitoring unit. For example, when the control unit monitors that the pressure value is greater than 140mmHg, the driving unit is controlled to cut off power and stop running to stop inflating the dual-chamber airbag. When it is monitored that the amplitude of the pulse fluctuation at this time exceeds 15%, the driving unit is controlled to reverse to discharge the gas from the dual-chamber airbag. It should be noted that the relevant pressure value and pulse value can be set according to the actual needs of the user, and no specific limitation is made here. Thereby, the real-time monitoring of the pulse fluctuation is achieved while massaging the limbs. When the pressure value reaches the first threshold and the fluctuation amplitude of the pulse fluctuation is greater than the second threshold, the massage device is automatically turned off to stop massaging the limbs. Compared with the existing limb massagers, the convenience and safety are improved.

[0038] It should be understood that when the airbag is inflated to a certain degree, the pressure sensor will sense the pressure changes in the artery. Since the pressure of the artery will fluctuate regularly during the heart beat of the human body, these fluctuations can be captured by the pressure sensor and converted into electrical signals. The control unit can determine parameters such as the pulse rate and intensity by analyzing the frequency and amplitude of these electrical signals.

[0039] Ginseng Figure 2FIG. 2 is an exploded schematic diagram of the limb massage device for monitoring pulse of the present application. The double-chamber airbag 2 includes a first airbag 21 corresponding to the proximal end of the limb and a second airbag 22 corresponding to the distal end of the limb, and the first airbag 21 and the second airbag 22 are connected via a solenoid valve 35.

[0040] The first airbag 21 and the second airbag 22 are both inflatable and deflated airbags, and the first airbag 21 is closer to the heart than the second airbag 22. When the massage device enters the working mode, the driving unit rotates forward to inflate the input end of the second airbag 22, and the air pressure flows from the output end of the second airbag 22 to the first airbag 21 through the solenoid valve 35, so that the first airbag 21 and the second airbag 22 are inflated at the same time.

[0041] Furthermore, the solenoid valve 35 can be a two-way solenoid valve (for example, a two-position two-way valve), the driving unit is connected to the input end of the second airbag 22, the output end of the second airbag 22 is connected to the input end of the two-position two-way valve, and the output end of the two-position two-way valve is connected to the input end of the first airbag 21.

[0042] When the two-position two-way valve is not powered, the input end and the output end of the two-position two-way valve are in a connected state, and when powered, the input end and the output end of the two-position two-way valve are in a closed state. Therefore, when the two-position two-way valve is not powered, the driving unit can inject gas into the first airbag 21 through the second airbag 22 to inflate the first airbag 21.

[0043] Furthermore, the monitoring unit includes a first sensor 31 and a second sensor 32. A first air nozzle connected to the first air bag 21 is provided above the first air bag 21. The first sensor 31 is used to monitor the pressure value of the first air bag 21 through the first air nozzle.

[0044] A second air nozzle connected to the second air bag 22 is provided above the second air bag 22 , and the second sensor 32 is used for monitoring the pressure value of the second air bag 22 through the second air nozzle.

[0045] The first sensor 31 and the second sensor 32 are both pressure sensors. When the driving unit rotates forward to inflate the input end of the second airbag 22, the second sensor 32 can monitor the pressure value of the second airbag 22 and feed it back to the control unit. Since the driving unit injects gas into the first airbag 21 through the second airbag 22, the first sensor 31 can also monitor the pressure value of the first airbag 21 and feed it back to the control unit.

[0046] Furthermore, the driving unit includes an air pump 33, and the working state of the air pump 33 includes a forward working state and a reverse working state.

[0047] The air pump 33 can be a micro air pump with an integrated pump and valve. The working states of the micro air pump include a forward working state and a reverse working state. The forward working state is used to inflate the second airbag 22, and the reverse working state is used to discharge the gas in the second airbag 22.

[0048] The scheme of the present application is further described with reference to the standard operation mode of the massage device, which can include a gentle model, a standard mode, and a strong mode. When the massage device enters the standard mode, the pump-valve integrated micro air pump is powered on and enters the forward working state (forward rotation) to inflate the second airbag 22. At this time, the second sensor 32 receives the pressure signal and displays the pressure value of the second airbag 22 in real time on the display interface of the control host 3. The gas comes out from the air nozzle connector at the other end of the second airbag 22 and passes through the solenoid valve 35 to the first airbag 21. At this time, the first sensor 31 can monitor the pressure value of the first airbag 21. The pressure value monitored by the first sensor 31 is recorded by the control unit and is not displayed.

[0049] When the control unit detects that the pressure value reaches above 100 mmHg, the control unit controls the solenoid valve 35 to energize, that is, to disconnect the gas injection from the second airbag 22 to the first airbag 21. At this time, the micro air pump continues to run to inflate the second airbag 22. When the second sensor 32 cannot detect a pulse signal (assuming that the systolic blood pressure of the human body is 120 mmHg at this time, when the pressure of the second airbag 22 exceeds 120 mmHg, the second sensor 32 cannot detect a pulse signal), after the pressure value at this moment continues to increase by 30-40 mmHg, the control unit controls the micro air pump to cut off the power and stop running. At this time, the operating state in the display interface shows "pressurized", and the pressure in the pressurized state is maintained for 1 minute. In the process of maintaining the pressure, the first sensor 31 monitors the pulse rate in real time. When the pulse fluctuation amplitude exceeds 15% or 20%, the emergency state is entered. At this time, the control unit controls the micro air pump to be powered on and enter the reverse working state (reverse rotation). The valve on the micro air pump is opened, so that the gas in the second air bag 22 is discharged through the valve of the micro air pump. After 2 seconds, the control unit controls the electromagnetic valve 35 to be powered off. At this time, since the input end and the output end of the electromagnetic valve 35 are connected, the gas in the first air bag 21 flows back to the second air bag 22 through the electromagnetic valve 35, and then discharged through the valve of the micro air pump, thereby entering the relaxation state. If the pulse fluctuation amplitude monitored by the first sensor 31 does not exceed the set value within 1 minute of maintaining the "pressurized" state, the relaxation state is entered for 3 minutes. 1 minute of pressure and 3 minutes of relaxation can be used as stage 1 of the massage process, and the massage can also be continued in stages 2 (for example, 2 minutes of pressure and 3 minutes of relaxation), stage 3 (3 minutes of pressure and 5 minutes of relaxation), stage 4 (5 minutes of pressure and 5 minutes of relaxation), etc.

[0050] By adopting the above scheme to perform limb massage, the first airbag 21 can monitor pulse changes in real time under a fixed pressure, and the second airbag 22 can block and release limb blood flow, which improves convenience and safety compared to existing limb massagers.

[0051] Furthermore, the control host 3 also includes a power supply 34, and the power supply 34 is connected to the solenoid valve, the driving unit and the control unit respectively.

[0052] The power source 34 may be a rechargeable power source, which is respectively connected to the solenoid valve 35 , the drive unit and the control unit, so as to supply power to the solenoid valve 35 , the drive unit and the control unit.

[0053] Furthermore, the control host 3 also includes a shell, which includes an upper shell and a lower shell detachably connected to the upper shell, and a cavity is formed between the upper shell and the lower shell, and the power supply 34, the control unit, the drive unit, the monitoring unit and the solenoid valve are located in the cavity.

[0054] The power supply 34, control unit, drive unit, monitoring unit and solenoid valve 35 are all located in the cavity, and the first sensor 31, the second sensor 32 and the control unit are arranged on the PCB circuit board, and the PCB circuit board is located in the cavity. The power switch can be a physical button, and the switch button can be arranged on the shell. The user presses the power switch for a long time to turn on and enter the standby state. At this time, the WIFI icon of the control host 3 flashes and waits for the scan code to connect. Press the power switch again to enter the standard mode, press it again to enter the strong mode, and press it again to enter the gentle mode. The sequence keeps scrolling. If there is no operation within 2 seconds, the corresponding mode is started.

[0055] Furthermore, the control host 3 also includes a display unit, which is arranged on the surface of the shell, and is used to display the pressure value of the second airbag 22 in real time.

[0056] The display unit is arranged on the surface of the shell, and the display unit can display the pressure value of the second airbag 22 in real time. The power switch button can also be a virtual button, which can be arranged in the display unit. The display unit can also display the connection status of WIFI, the "pressurization" or "relaxation" status of the massage device, and the "pulse monitoring" status, etc.
