Description

Technical Field

[0001] This utility model relates to the field of medical and health care device technology, specifically to a vacuum negative pressure detection device for a glass cupping device. Background Technology

[0002] Cupping is a therapy that uses cupping devices to create negative pressure through methods such as burning or suction, causing the cups to adhere to the body surface and create local blood stasis. This achieves the effects of clearing the meridians, promoting blood circulation, reducing swelling and pain, and dispelling wind and cold.

[0003] Traditional glass cupping sets without a top opening create negative pressure through combustion to adhere to the skin surface. Under normal use, the negative pressure is typically required to be between -54.57 kPa and -62.38 kPa; in extreme cases, the negative pressure can be even higher. For glass cupping sets without a top opening, the negative pressure value cannot be visually displayed, and existing testing devices cannot detect the generated negative pressure. This can lead to insufficient or excessive suction, causing discomfort and posing safety hazards to patients and users. For example, if the negative pressure cannot be maintained, the glass cupping set may fall off or break. Conversely, excessive negative pressure can cause substandard glass cupping sets to crack or break, with broken glass shards posing a personal injury to patients and users. Furthermore, the testing of negative pressure in glass cupping sets may pose safety risks to the personnel performing the testing.

[0004] In view of this, how to solve the safety hazards and product stability problems caused by the inability to perform negative pressure testing on glass cupping devices without top through holes in the existing technology has become the research topic to be solved by this utility model.

[0006] To achieve the above objectives, this utility model proposes a vacuum negative pressure detection device for glass cupping devices, used for negative pressure detection of glass cupping devices. The negative pressure detection device has the following features:

[0007] The testing platform is equipped with a flexible pad for sealing the opening of the glass cupping device to form a closed space.

[0008] The air extraction assembly includes an air extraction connecting pipe, an air pipe connecting valve, and a vacuum generator. One end of the air extraction connecting pipe passes through a flexible pad and is connected to the sealed space, while the other end is connected to the air pipe connecting valve and the vacuum generator in sequence.

[0009] The pressure gauge is connected to the air pipe connection valve and is connected to the air extraction connection pipe and the sealed space.

[0010] A check valve is a one-way valve body structure that prevents gas backflow. The check valve is installed on the gas connection pipe between the gas pipe connection valve and the vacuum generator.

[0011] The negative pressure detection device is configured to form a negative pressure detection circuit within the air extraction connecting pipe between the check valve, the pressure gauge, and the sealed space.

[0012] The relevant contents of this utility model are explained as follows:

[0013] 1. The above-mentioned technical solution of this utility model mainly provides a vacuum negative pressure detection device that is simple in structure, low in cost, and does not affect the use of traditional glass cupping devices without top openings. This vacuum negative pressure detection device includes a detection platform, a suction assembly, a pressure gauge, and a check valve. The detection platform is equipped with a flexible pad for forming a sealed space by tightly sealing the opening of the glass cupping device. The suction assembly includes a suction connecting pipe, a gas pipe connecting valve, and a vacuum generator. One end of the suction connecting pipe passes through the flexible pad and connects to the sealed space, while the other end is sequentially connected to the gas pipe connecting valve and the vacuum generator. The pressure gauge is connected to the gas pipe connecting valve and is also connected to the suction connecting pipe and the sealed space. A negative pressure detection circuit is formed within the suction connecting pipe between the check valve, the pressure gauge, and the sealed space. In use, the glass cupping device to be tested is placed face down on the flexible pad, and the vacuum generator of the vacuum negative pressure detection device is activated. A vacuum is drawn, and a check valve ensures unidirectional airflow to prevent backflow during the vacuuming process. A flexible pad fits tightly against the opening of the glass cupping device to create a sealed testing space, ensuring no gas leakage during vacuuming, guaranteeing the accuracy of negative pressure testing, maintaining the stability of the internal negative pressure of the glass cupping device, and avoiding fluctuations in test data. This device effectively tests the negative pressure resistance and pressure maintenance performance of the glass cupping device. The negative pressure resistance of the glass cupping device can be tested by measuring the instantaneous maximum pressure generated by the vacuum generator, and the pressure maintenance performance can be tested by measuring the internal negative pressure generated by the vacuum generator pump. This device can effectively test the negative pressure resistance and pressure maintenance performance of glass cupping devices without a top opening, overcoming the shortcomings of traditional pressure testing technology for glass cupping devices, improving and ensuring the pressure stability of glass cupping devices in clinical use, and ensuring the safety of patients and clinical users.

[0014] 2. In the above technical solution, the negative pressure detection device also has a power supply control component, which includes a power supply, a transformer, a relay, and an on / off valve. The on / off valve is located between the vacuum generator and the check valve. The relay is electrically connected to the transformer, pressure gauge, and on / off valve. The power supply is electrically connected to the transformer and vacuum generator. The power supply can be 220V AC mains power, which directly supplies power to the vacuum generator. The 220V power supply is converted by the transformer to output the required operating voltage of 24V for the device, providing a stable power supply for subsequent circuits. This power supply control component provides a more stable power supply and more reliable and efficient circuit control.

[0015] 3. In the above technical solution, the pressure gauge is a digital display electronic pressure gauge with a built-in pressure sensor. The pressure sensor is connected to a signal processing circuit, an analog-to-digital converter module, and a display unit. It senses changes in air pressure in the detection circuit in real time through a suction connection pipe. The pressure sensor converts the physical quantity of air pressure into a weak electrical signal, which is amplified and filtered by the internal signal processing circuit. The analog signal is then converted into a digital signal by the analog-to-digital converter module. The processed digital signal is transmitted to the display unit, presenting the negative pressure value inside the glass cupping device in an intuitive digital form. This achieves accurate acquisition and visual feedback of negative pressure data, providing real-time data reference for testing personnel.

One side of the bottom of the protective cover is hinged to the testing platform, and a handle is installed on the other side wall to better open and close the protective cover.

[0018] 6. In the above technical solution, the upper end of the air extraction connecting pipe is connected to the connector, and the connector is fixed to the flexible pad by a flange, so as to install the air extraction connecting pipe more stably and firmly on the flexible pad without affecting the air tightness after air extraction.

A pressure plate with a hollow center is then fixedly installed on the upper surface of the flexible pad, so as to better install and position the flexible pad on the testing platform. The pressure plate assists in positioning and pressing the flexible pad, so that even after the glass cupping device is placed on the flexible pad and air is evacuated, it can still effectively support the glass cupping device and effectively form a sealed space between the flexible pad and the glass cupping device.

[0020] 8. In the above technical solution, the flexible pad is made of silicone to simulate the human skin environment, making the negative pressure detection process closer to the actual use scenario.

The negative pressure resistance of the glass cupping device 9 can be tested by measuring the instantaneous maximum pressure generated by the vacuum generator 23, and the pressure maintenance performance can be tested by measuring the negative pressure inside the cupping device generated by the vacuum generator 23 pump.
