Handheld low-temperature plasma jet device and use method thereof

Abstract

The invention discloses a handheld low-temperature plasma jet device and a use method thereof. The handheld low-temperature plasma jet device comprises a handle, a switch assembly, a rotating structure, a flow slowing structure, a swinging structure, an air duct, an air supplementing structure and a plasma pulser; the flow slowing structure is installed at the top end of the air duct; the rotating structure is adopted, during the use of the device, the surface side of the handle is held, frosted sponge is arranged on the handle, the friction force between the palm and the handle can be improved, the handheld stability can be improved; a motor is powered on, a driving gear is driven to rotate, and under cooperation of a matched gear, rotation of a rotating shaft can be achieved; and by changing the relative included angle between the handle and the air duct, the spraying direction of the air duct can be changed while a proper handheld position is guaranteed, the handheld stability is improved, arm fatigue caused by the fact that an arm keeps one action for a long time is avoided, the holding direction of the handle can be changed randomly, the holding direction of the arm can be adjusted randomly, and the arm can be better protected, and the stability of the handheld mode is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a hand-held low-temperature plasma jet device and a use method thereof. Background technique [0002] Dielectric barrier discharge can generate stable low-temperature plasma under atmospheric pressure. Compared with other low-temperature plasma generation methods, it is more suitable for large-scale industrial production. It has broad application prospects and has attracted the attention of many researchers. Especially in recent years, low-temperature plasma technology has been widely studied and applied in the field of biomedicine. People are trying to use plasma to replace or assist drugs and traditional medical methods to achieve better therapeutic effects, which can not only avoid The side effects of drugs on the human body will not cause damage to the environment; [0003] The low-temperature plasma therapy instrument disclosed in the existing published applicati...

Problems solved by technology

[0003] The low-temperature plasma therapy instrument disclosed in the existing published application CN201910836776.X has structures such as a plasma generator, a radio frequency source, an argon gas bottle, and a helium gas bottle. The gas mixing tank is connected, the gas mixing tank is connected with the plasma generator to provide mixed gas, the man-machine interface is connected with the gas flow controller and the radio frequency source through PLC, and the gas flow controller and the radio frequency source are respectively controlled, and the radio frequency The source is connected to the plasma generator for plasma generation. This method can realize irradiation treatment on the skin of the patient's affected area, but there are many structures and it is more troublesome to use;

[0004] The handle of the existing low-temperature plasma jet device is relatively fixed to the jet device. When it is used for a long time, the arm is overworked and sore, which is unfavorable for handheld operation. The existing wind plasma jet device has a fixed structure and can only Sweep the wound by swinging the arm. It cannot be sprayed in a large area, which will consume a lot of physical strength and increase the work intensity of the medical staff.
