Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a low-temperature hot gas therapeutic device. Background Art

[0002] Injury to human muscle tissue can cause local congestion or bleeding, leading to inflammation and pain. In the early stages of local soft tissue injury, cold therapy can shrink capillaries, reduce bleeding and slow swelling. At the same time, cold therapy can reduce the excitability of human neurons and relieve pain. In the recovery period of muscle tissue contusion, heat therapy can accelerate blood flow, promote the dissipation and spread of inflammation, reduce congestion and swelling of deep tissues, relieve pain caused by joint and muscle spasms, and promote wound healing.

[0003] Cold and hot therapy has occupied an important position in modern rehabilitation therapy. Traditional cold therapy usually uses local ice packs, ice caps, and chemical cooling bags for treatment. Although these methods can achieve the purpose of cold therapy, they are troublesome to make and store, and the temperature is below zero, and the temperature cannot be controlled during treatment. Traditional heat therapy usually uses hot water bags and chemical heating bags for treatment, which also have the problem of troublesome production and storage, and the treatment temperature cannot be controlled.

[0004] To solve the above problems, gas therapy devices are currently used to replace ice packs, cold packs or electric heating to improve the efficiency of treatment. The specific implementation scheme is as follows:

[0005] 1. Use a low-temperature shock analgesic device for cold therapy. This type of device uses liquefied gas and uses the principle of gas sublimation and heat absorption for cold therapy, which can not only reduce inflammation but also has analgesic effects. The disadvantages of this solution are: the treatment scenario is single, it only has the function of cold therapy, but not the function of heat therapy; and it needs to use liquefied gas, and when the gas is consumed, it needs to be replaced manually, which increases the labor cost. The liquefied gas will take away a lot of heat when it is vaporized. When it is vaporized for a long time, its temperature often reaches below zero degrees Celsius, and improper user operation will cause low-temperature damage. At the same time, the liquefied gas used must be food grade or above, which also increases the cost of use.

[0006] 2. Use a heating lamp or a hair dryer for heat therapy. The disadvantage is that the treatment scenario is single, and the heating method using a heating lamp or a hair dryer only has the function of heat therapy, but not cold therapy.

[0007] 3. Use low-temperature hot gas therapy devices for heat therapy. Such devices use air cooling or electric heating rods to heat the gas for treatment. There are problems with poor cooling and heating efficiency and long switching time between hot and cold. Utility Model Content

[0022] Furthermore, the air gun assembly includes a gun body, a hose arranged at the rear end of the gun body, and an infrared temperature sensor and a nozzle arranged at the front end of the gun body; one end of the hose is connected to the nozzle, and the other end is connected to the third air outlet; a digital tube connected to the infrared temperature sensor is provided on one side of the gun body; and the outer periphery of the hose is covered with thermal insulation cotton.

[0023] Furthermore, the low-temperature hot gas therapy device also includes a touch control screen, which is electrically or communicatively connected to the gas compression component, the first three-way solenoid valve, the second three-way solenoid valve, the heating plate, the semiconductor refrigeration plate and the temperature sensor respectively.

[0026] 1.

That is, the compressed air is heated or cooled by liquid heating and liquid cooling. This method greatly improves the efficiency of heating and cooling, and solves the problem of low cooling and heating efficiency of current low-temperature hot gas therapy devices. At the same time, a three-way valve is used to control the conduction with an electrical signal, so that the switching between cold air and hot air can be completed within a few seconds.

[0027] 2. This device compresses the air first and then outputs it separately for heating or cooling. Different from the existing method of compressing the heating gas and the cooling gas separately, this device adopts the method of compressing first and then heating or cooling separately, which improves the space utilization.

[0028] 3. In the compression stage of gas pretreatment, double filters are used to filter impurities in the air, and desiccant is used to absorb water vapor in the air to prevent the liquefaction of water vapor and cause gas path blockage. A pressure sensor is used in the gas cylinder to replace the traditional mechanical barometer. When the compressed gas in the gas cylinder is consumed to the set threshold, the compressor will restart to inflate it to the level, making it more convenient to use and improving the automation of the device.

[0029] 4. Temperature sensors for monitoring temperature are provided at the outlet ends of the first air pipe and the second air pipe.
