Plasma disinfection and sterilization device for medical instruments

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The embodiments of the present invention, and all other embodiments obtained by those of ordinary skill in the art without creative work, fall within the protection scope of the present invention.

[0023] The plasma disinfection and sterilization device of the present invention is such as figure 1 As shown, it includes a metal frame 5 for placing medical instruments to be sterilized, a high-voltage device 2, an array electrode 3 generated by the upper plasma, and an array electrode 4 generated by the lower plasma, a gas discharge area 1, a sterilization area 7, and an air inlet area 8. The vent 9 is constituted. The array electrode 3 generated by the upper plasma and the array electrode 4 generated by the lower plasma are cylindrical electrodes.

[0024] The actual operation process is to put the medical equipment that needs disinfection and sterilization on the metal frame 5, close the door, and install a magnetic strip at the joint of the door, and the outer surface is wrapped with rubber products, so as to achieve a better airtight effect. Compressed gas with a pressure of not less than 0.5Mpa enters the gas discharge zone 1 from the inlet zone 8. The voltage range of the high-voltage power supply is 10Kv-15kv and the frequency is 13.56MHz. The array electrode is a metal plate with a circular hole inside a cylindrical structure, made of tungsten copper alloy, the distance between the cylindrical array electrodes is 10mm, and the array electrode 3 generated by the upper plasma and the array electrode 4 generated by the lower plasma are connected to high voltage The positive and negative electrodes are spaced 5mm apart, and the electrode plate 10 is grounded, which is a ground electrode. The plasma generated by the high-voltage discharge is blown out from the vent 6 into the disinfection room to realize the disinfection treatment of the medical equipment. The outside of the device is equipped with a timing system, and the processing time can be set manually. After the processing time is completed, the plasma generator stops working, the array electrode 3 generated by the upper plasma and the array electrode 4 generated by the lower plasma stop discharging, and the exhaust hole 9 is fully opened at the same time to exhaust the gas, so that the inside and outside of the device reach atmospheric pressure balance. The disinfection room is equipped with a pressure measuring device. When the pressure is too high, the device will alarm and force the plasma generator to stop working to ensure that the equipment is not damaged and the safety of the operator. After the disinfection is over, open the door to take out the disinfected medical instruments and use them for future related work.

[0025] The beneficial effects of the present invention are: use plasma technology to sterilize medical devices, generate plasma through high-pressure breakdown of compressed gas, use active substances such as electrons and ions in the plasma, and bacteria remaining on the medical devices after cleaning The virus reacts to kill microorganisms and achieves disinfection and sterilization.

[0026] For those skilled in the art, it is obvious that the present invention is not limited to the details of the foregoing exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, regardless of the point of view, the embodiments should be regarded as exemplary and non-limiting. The foregoing descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modification, variation, equivalent replacement and improvement made without creative labor are made to the above embodiments based on the technical essence of the present invention. All should be included in the protection scope of the present invention.
