Description

Negative pressure oxygen therapy machine

The present invention is a negative pressure oxygen therapy machine, which is a spa machine that provides water with high density ozone dissolved therein.

Ozone Therapy (Ozone Therapy) is one of the research projects in the medical field in recent years. It enhances the body's antioxidant capacity by introducing ozone into the human body to improve the body's antioxidant capacity, thereby regulating the function of the body.

There are many ways to introduce ozone. One of them is an ozone bath. The ozone dissolved in water is absorbed by the subcutaneous capillaries through the skin, and then transferred to various organs of the body through the blood circulation to regulate the function of each organ. Accelerate metabolism, so that waste (such as sweat, lipids, anaerobic bacteria, lactic acid, uric acid, etc.) in the body can be excreted through reverse osmosis with water. The higher the oxygen content in the water, the higher the The concentration absorbed makes the effect more significant.

Moreover, a common way in the prior art is to use a high pressure chamber to provide high purity oxygen for the user to inhale. However, for the user, the user must be under a high pressure environment to perform the treatment, at high pressure. The environment will cause many side effects on the human body, such as pressure damage in the lungs, eardrums, and sinuses. High concentrations of oxygen may cause convulsions, and the crystals may become swollen and affect vision.

Therefore, how to provide high concentration of ozone into the human body under normal temperature and normal pressure has become one of the focuses of medical research.

In view of this, the creation department created a negative pressure oxygen therapy machine to provide users with the need to perform an ozone bath in a high pressure environment.

In order to achieve the above-mentioned creative purposes, the technical means used in the creation is to create a negative pressure oxygen therapy machine, which comprises: a soaking pool, which is provided with a water outlet, a water inlet, and a drainage hole; a first motor, It is connected to the water outlet of the immersion tank; a second motor is connected to the water inlet of the immersion tank; a cage is respectively connected to the first motor and the second motor, and the cage is provided a curved water-gas fusion path; an ozone generator coupled to the cage; a control system electrically coupled to the first motor, the second motor, and the ozone generator for transmission control Signaling to control the first motor, the second motor and the ozone generator; wherein the first motor drives the water in the soaking pool into the cage when the control system controls the operation of the first motor When the control system controls the operation of the ozone generator, the ozone generator sends the generated ozone into the cage; when the control system controls the second motor to operate, the second motor melts The water in the gas mixture to play back the soaking pool.

The advantage of this creation is that through the curved water-gas fusion path provided in the cage, and the continuous water circulation, the ozone and water can be fully mixed to enhance the density and molecular fineness of ozone in the water, and the user can Ozone bath at normal temperature and pressure to massage the body and increase metabolism The ability, high-density water-gas mixture penetrates into the user's skin and is carried into the blood to act on the human body.
