Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 As shown, the plasma puncture jet device of the present invention is made up of gas delivery device and plasma generator; 1. The gas valve 2 and the flow meter 3; the gas conveying device and the plasma generating device are connected with each other using the gas guide tube 4, and the connected interface is sealed to ensure that there is no gas leakage during the conveying process. The air duct passes through the handle 5 to deliver the gas to the metal needle housing 8 .

[0022] The metal needle-shaped housing 8 has a shaft length of 10-20cm and a diameter of 1-1.5mm. One end is pinhole-shaped, and the other end is connected to the handle 5. The gas starts from the gas cylinder 1, passes through the gas valve 2, the flow meter 3 and the handle 5, and reaches the plasma generator, and discharges between the high-voltage ele...

Abstract

The invention provides a low-temperature plasma articular cavity puncture jet device. A parallel plate structure discharge device is used for discharging to generate atmospheric pressure plasma, a discharge area is in an electrode gap, the discharge gap is usually small and is in the magnitude of millimeter to centimeter, the thickness and the size of a processed object are limited by the discharge gap, which means that when the processed object is placed in the discharge gap, a dielectric layer is added between electrodes, the discharge characteristic can be affected, plasma jet does not generate plasma in the gap, and high-energy particles and active ingredients in the discharge area are conveyed to the surface of a sample under the action of airflow and an electric field. The device is simple and easy to disassemble, the generated plasma jet has many active particles, use is safe, and application processing of the device is facilitated.

Description

technical field [0001] The invention relates to the field of low-temperature plasma technology, in particular to a low-temperature plasma joint cavity puncture jet device. Background technique [0002] Rheumatoid arthritis (rheumatoid arthritis, RA) is a common autoimmune joint disease. RA has a high disability rate and serious harm, which has a continuous impact on the life and work of patients. The main manifestation of RA in the human body is Synovial hyperplasia, local inflammation, and destruction of adjacent bone and cartilage. At present, the main method for the treatment of local symptoms of RA joints is drug treatment, which mainly relies on glucocorticoids and non-steroidal anti-inflammatory drugs. Drug treatment measures Although it can alleviate the patient's symptoms, the effect is short-lived, the side effects are large, and the patient is prone to dependence on the drug, especially the effect on the target joint has little effect. [0003] Plasma is a form of...
