Embodiment 1

[0083] The reaction chamber is separated by an ion exchange membrane, and the electrolytic electrode is discharged by a DC high-voltage power supply for 5 minutes. At this time, the solutions in the anode and cathode chambers become acidic solution and alkaline solution respectively, and the two solutions are proportioned according to the pH value. Weak alkaline solution in the range of 9-10, and passed into the mixing chamber, 1L / min air was passed into the plasma generator, and air plasma was generated under high pressure to acidify the mixed solution, and the final The resulting neutral plasma-activated aqueous solution was used for inactivation of T24 cells and Staphylococcus aureus. pass figure 2 It can be seen that with the increase of cell treatment time, the inactivation effect of cells is better, from image 3 In the results, neutral plasma-activated water showed better sterilization effect. from Figure 4 It can be seen from the results in that the pH value of th...

Abstract

The invention discloses a neutral plasma activated water preparation device and method based on an ion exchange membrane. A reaction chamber is divided into an anode chamber and a cathode chamber by the ion exchange membrane for ion exchange in an aqueous solution; the mixing chamber is connected with the cathode chamber through a third peristaltic pump so as to pump an alkaline solution, the mixing chamber is connected with the acidic potential water outlet through a second peristaltic pump so as to pump an acidic solution, and the alkaline solution and the acidic potential water are mixed in proportion; the monitoring and control circuit is connected with the power controller, the pH monitor, the one-way valve and the first to fourth peristaltic pumps, sends a power signal to the power controller to control the electrolysis electrode and / or the plasma generator, and sends a water quantity signal to the second peristaltic pump, the third peristaltic pump and the fourth peristaltic pump based on the pH value; based on the water discharge of the first peristaltic pump and the third peristaltic pump, the monitoring and control circuit sends a water quantity signal to the one-way valve.

Description

technical field [0001] The invention belongs to the field of plasma medicine, in particular to an ion exchange membrane-based neutral plasma activated water preparation device and method. Background technique [0002] Infections such as cancer and bacteria and viruses have always been the focus of prevention and attention in the medical field. Cancer is one of the main threats to human health in modern society. Traditional surgical treatment, chemotherapy and radiotherapy often have problems such as postoperative recurrence and toxic side effects, which have been difficult to meet people's needs for cancer treatment. In addition, at present, humans mainly use antibiotics to fight against bacteria. However, the abuse of a large number of antibiotics will cause bacteria to develop drug resistance and cannot be completely eradicated, and further cause superinfection of the body and serious side effects. Therefore, it is particularly important to seek novel, safe and effective ...
