AI Technical Summary
Existing air wave pressure therapy devices cannot achieve localized treatment. When the airbags are inflated, all airbags inflate simultaneously, which cannot meet the needs of personalized treatment.
An intermittent air pressure instrument was designed, which uses individually pressurizable airbags, solenoid valves, pressure sensors, and microcontrollers to achieve independent control and sealing of each airbag. The solenoid valves and microcontrollers enable individual pressurization and depressurization of the airbags, and the pressure sensors enable real-time detection and control.
This achieves improved precision and pressure effect in local treatment, reduces equipment power consumption, and enhances the targetedness and efficiency of treatment.

Abstract
Description
Technical Field
[0001] This utility model relates to an intermittent air pressure meter. Background Technology
[0002] In rehabilitation therapy, air wave pressure therapy devices play an important role in treating diseases such as varicose veins and lymphedema. However, in existing air wave pressure therapy devices, each air bag is interconnected during treatment. For example, in the DSM-4S model, inflation can only fully inflate each air bag, preventing localized treatment. Utility Model Content
[0003] In view of the above, this utility model provides an intermittent air pressure instrument to solve the problems existing in the prior art.
[0004] According to one aspect of the present invention, an intermittent air pressure device is provided, including a main unit, an inflation hose, and a pressure bag assembly that can apply corresponding pressure according to the condition of the human limb for physiotherapy. The lower end of the inflation hose is connected to the output end of the main unit, and the upper part is connected to the pressure bag assembly. A pressure relief port is provided at the upper end, and a pressure relief valve is provided at the pressure relief port.
[0005] The pressurized airbag assembly includes an airbag that can be individually pressurized and forms a sealed space with the skin to enhance pressure, an electromagnetic valve that connects each airbag to an inflation hose, a pressure sensor, and a microcontroller. The airbags are ring-shaped and interconnected in segments. Each airbag has a groove on one side for placing the inflation hose. The connections on both sides of each airbag are sealed, and each airbag has a through hole in its groove. The upper part of the inflation hose has multiple air outlets corresponding to the through holes. The air outlets are sealed around their perimeter and connected to the corresponding through holes. The electromagnetic valve is located inside the air outlet. The pressure sensor is located on the inner wall of each airbag. The microcontroller is located inside the main unit. The pressure sensor is connected to the input end of the microcontroller, and the electromagnetic valve is connected to the output end of the microcontroller.
[0006] Preferably, each airbag has a sealing rubber ring on the inner side of its connection point that can contact the skin to form a relatively sealed space.
[0007] The beneficial effects of this utility model are as follows:
[0008] By setting each airbag individually, the airbag can apply pressure to a specific part of the body for localized treatment. The relatively sealed design of each airbag improves the pressure effect, achieving a greater pressure effect with less air and reducing the power consumption of the main unit.

[0011] The present invention will be further described below with reference to the accompanying drawings and some embodiments.
[0012] Figure 1 In the present invention, an intermittent air pressure device includes a main unit 1, an inflation hose 2, and a pressure bag assembly that can apply corresponding pressure according to the condition of the human limb for physiotherapy. The lower end of the inflation hose 2 is connected to the output end of the main unit 1, and the upper part is connected to the pressure bag assembly. The upper end is provided with a pressure relief port, and a pressure relief valve 3 is provided at the pressure relief port.
[0013] The pressurized airbag assembly includes an airbag 4 that can be individually pressurized and forms a sealed space with the skin to enhance the pressure effect, an electromagnetic valve 6 that connects each airbag 4 to an inflation hose 2, a pressure sensor 7, and a microcontroller 8. The airbag 4 has a ring-shaped structure and is connected to each other in a segmented manner. Each airbag 4 has a groove on one side for placing the inflation hose 2. The connection points on both sides of each airbag 4 are sealed, and each airbag 4 has a through hole in the groove. The upper part of the inflation hose 2 has multiple air outlet pipes corresponding to the through holes. The air outlet pipes are sealed around the perimeter and connected to the corresponding through holes. The electromagnetic valve 6 is located inside the air outlet pipe. The pressure sensor 7 is correspondingly located on the inner wall of each airbag 4. The microcontroller 8 is located inside the main unit 1. The pressure sensor 7 is connected to the input end of the microcontroller 8, and the electromagnetic valve 6 is connected to the output end of the microcontroller 8.
[0014] In this embodiment, each airbag 4 has a sealing rubber ring 5 on the inner side of its connection point that can contact the skin to form a relatively sealed space; the main unit 1 is equipped with switches for multiple corresponding solenoid valves 6.
[0015] In this embodiment, the microcontroller 8 is model AT89C2051 or TMS320VC5509A, etc.
[0016] In the specific implementation of this embodiment:
[0017] When a localized massage or physiotherapy is needed, the airbag 4 is worn on the body limb, the corresponding switch is turned on, which opens the corresponding solenoid valve 6. The pressure sensor 7 monitors the pressure data of the corresponding airbag 4 in real time and transmits it to the microcontroller 8. After the pressure reaches the set value, the microcontroller 8 transmits information to the solenoid valve 6, causing the solenoid valve 6 to close. After the set physiotherapy time, the solenoid valve 6 opens, and the pressure relief valve 3 opens to complete the physiotherapy. If it is used for massage, after the pressure reaches the set value, the microcontroller 8 transmits information to the pressure relief valve 3 and turns off the air supply of the main unit 1, causing the pressure relief valve 3 to open and release pressure. After the pressure sensor 7 in the corresponding airbag 4 reaches the set value, the pressure relief valve 3 closes, and the main unit 1 opens to release air and pressurize. The above operation is repeated to perform massage.

The device of this utility model can be connected to an external power source or a built-in battery through a power cord to provide power to the device. Those skilled in the art can implement it, so it will not be described in detail here.
