Low-temperature plasma sterilization pen

Abstract

The invention discloses a low-temperature plasma sterilization pen. The low-temperature plasma sterilization pen comprises a shell with an inlet and an outlet, and a low-temperature plasma generator,a power supply, a gas control unit and a pen point which are arranged in the shell, wherein the shell is arranged in a pen shape capable of being held by a hand, the pen point is arranged in the shellin a sliding manner, the pen point is arranged to at least partially extend outwards from the outlet of the shell, the pen point comprises a plurality of sections of through pipes made of a dielectric material, every two through pipes are connected through flexible pipe joints in a communication manner, the gas control unit is used for conveying a gas into a pipe cavity of the pen point, the low-temperature plasma generator comprises at least one group of metal electrodes arranged in the pipe cavity of the pen point, each group of metal electrodes comprises a first metal electrode and a second metal electrode, the power supply is respectively connected with the first metal electrode and the second metal electrode, and the outer layer of the first metal electrode or second metal electrodeis coated with an insulating medium. According to the low-temperature plasma sterilization pen, the existence time of plasma is prolonged, the efficient, safe and all-around sterilization is realized,and particularly the portable carrying can be achieved.

Description

[0001] The present invention is filed June 21, 2017, Application No. 2017104723770 entitled "Low-temperature plasma sterilization pen," the divisional application Chinese invention patent applications. Technical field

[0002] The present invention belongs to the field of plasma application, in particular, to a wound sterilization suitable for human and / or animal body, the medical device fine microvoids sterilized, particularly to a low temperature plasma sterilization pen. Background technique

[0003] When material is continuously provided with energy, its temperature will rise, and then generally converted from solid to liquid to gas. Causes the system to continue to provide the energy state undergo further transitions, in this process, neutral atoms or molecules of gas to be opened collision energy, generating negative electrons, positive or negatively charged ions and other excited species. A mixture of charged and other excited particles of the above composition shows a se...
