Description
Technical Field
The invention relates to the technical field of articles for daily use, in particular to a portable rechargeable plasma sterilization pen.
Background
In daily life, outdoor travel and extended training, accidental injuries such as scratching by sharp objects, riding and falling scratches and accidental falling scratches in the course of travel are inevitable. If the wound is easily suppurative and infected by fungi and viruses if not treated in time, a small wound can be enough to harm the health of human body and threaten life safety. In order to deal with the situation, the traditional treatment method generally adopts the method of applying medicament for sterilization and disinfection, mainly adopts liquid and solid medicament such as alcohol, iodine, hydrogen peroxide and wound plaster, but the treatment methods have the main defects that: 1. the medicament is easy to expire; 2. poor portability; 3. chemical residues exist; 3. the effect of promoting wound healing is slow.
At present, people mostly adopt a sterilization device with sterilization efficacy to prevent and inhibit wound infection. As disclosed in patents CN101623506A, CN103747808A, CN106668897A and CN106421837A, the method of introducing inert gas or chemical agents for sterilization into the device can not only effectively inactivate pathogenic microorganisms such as various bacteria and viruses without damaging normal healthy cells, but also promote the healing of wounds to a certain extent. In addition, aiming at the injured and locally infected area, people can directly coat medicaments such as iodine, alcohol, hydrogen peroxide and the like under the guidance of medical care personnel, and the aim of inactivating pathogenic bacteria can be achieved.
However, the large device volume and safety and flexibility of wound treatment continue to be challenges for sterilization as described above. In outdoor or extended training, various wounds with different depths, complex shapes and unevenness can be caused by complex geographic and environmental factors, the existing device cannot flexibly and effectively treat the wounds, and part of the wounds cannot be treated correspondingly, so that part of fungi remain on the surface of the human body, and the sterilization effect is poor. In addition, the existing device only considers wound sterilization treatment, but does not consider the aspects of rapid hemostasis and healing of the wound, and is not beneficial to outdoor wound hemostasis treatment. Therefore, how to treat wounds outdoors flexibly, quickly and efficiently is still a social pain which troubles personal health and family safety.
The low-temperature plasma sterilization and disinfection technology almost has all the conditions of an ideal sterilization and disinfection method: compared with high-pressure steam sterilization and dry heat sterilization, the sterilization time is short; compared with chemical sterilization with 1, 2-ethylene oxide as a main body, the operation temperature is low; can be widely applied to sterilization of various materials and articles; biomedical application is an important direction for research and practical application of atmospheric pressure low-temperature plasma. On one hand, research and clinical application show that ROS and RNS substances in the atmospheric pressure low-temperature plasma can not only destroy the cell structure of microorganisms, but also induce the expression of vascular endothelial growth factors, promote wound epidermal regeneration, granulation tissue proliferation and collagen precipitation, and show positive effects in the aspects of sterilization, disinfection, hemostasis, coagulation, wound healing promotion and the like. On the other hand, the atmospheric pressure low-temperature plasma has good selectivity on bacteria and normal tissue cells, and the safety of healthy cell tissues can be ensured while inactivating the bacteria by optimizing and regulating parameters of the plasma. Therefore, the application of atmospheric pressure low temperature plasma to the prevention and treatment of fungal infection is a feasible technical approach.
The reasonable design of the reactor is the key for improving the generation and transportation efficiency of active particles and is the premise of plasma biomedical application. According to the difference of discharge principle, common reactors can be divided into two types of dielectric barrier discharge reactors and jet discharge reactors. Dielectric barrier discharge avoids the occurrence of arc discharge by inserting an insulating barrier dielectric between metal electrodes, thereby generating large-area low-temperature plasma; the jet discharge utilizes the combined action of the air flow and the electric field to convey active particles generated by ionization in the discharge area to the open area, so that the discharge area and the area to be treated are effectively separated.
Recently, researchers find that generating plasma in the form of air jet discharge has the advantages of high generation efficiency, high active particle content, strong operability and moderate cost, and meanwhile, the plasma has high discharge strength, strong particle activity and small thermal injury to human bodies. In addition, the content of nitric oxide in plasma can be effectively improved by adopting air jet discharge, researches prove that nitric oxide has a killing effect on bacteria, fungi and parasites, and a proper amount of nitric oxide can perform tissue acute inflammatory reaction, promote blood circulation and accelerate wound healing, so that a new solution idea is brought to sterilization, disinfection, hemostasis and blood coagulation on the surface of biological tissues and wound healing.
Therefore, the portable rechargeable plasma sterilization pen for outdoor wound rapid blood coagulation and efficient sterilization can be designed according to the requirements of outdoor rapid blood coagulation and efficient sterilization, the advantages of the application of atmospheric pressure low-temperature plasma biomedicine and the technical characteristics of air jet discharge.
Prior art solutions
For the requirement of wound treatment, the prior patent discloses a scheme adopting a plasma technology, and the plasma treatment method can be divided into a jet flow type, a dielectric barrier type and a flexible electrode type according to different working principles.
1) The jet type plasma utilizes the airflow to convey active substances generated in the discharge space to the skin wound, so that the active particles in the gaseous state can contact fungi on the wound while clotting blood, and the aim of sterilization is fulfilled. Like the jet plasma disinfection device disclosed in patent CN101623506A, the device is provided with a plasma generator, inert gas enters the gap and is jetted to medical instruments contained in the vessel from the plasma jet port to inactivate fungi, but the device is large in size, needs inert gas as working gas, is not flexible in overall use and is high in cost.
2) The dielectric barrier type plasma adopts an insulating material as a barrier dielectric, and generates plasma by discharging on the surface of the dielectric. As shown in the device disclosed in the CN106421837A patent, the micro-plasma dielectric barrier discharge technology is adopted, so that annular low-temperature plasma can be generated under the atmospheric pressure condition, the uniformity is good, and the sterilization time is short. However, the reactor has a complicated structure and is not highly safe.
3) As shown in the device disclosed in CN106668897A patent, the flexible electrode type plasma can sterilize and disinfect a surface object through a flexible dielectric layer and an elastic metal mesh, and has a simple structure and a small volume, but the device has poor selectivity and limited wound treatment objects.
1) Although research and practice have proved that the current jet type plasma sterilization device has positive effects on sterilization and wound healing, the requirement of a large amount of expensive inert gas still prevents wide-range clinical application and larger device volume cannot be applied to outdoor occasions, so that the device cannot be carried about and the application is limited.
2) Although the existing dielectric barrier type plasma sterilization device can directly generate a large amount of active particles in the air, the flexible reactor structure can ensure that the active particles are diffused and act on wounds. But is limited by the electrode processing technology, the structure of the reactor is complex, the heat dispersion is poor, and the service life is short.
3) The electrode at the suspension potential can directly contact the skin of the human body, and the safety of the human body contacting the plasma cannot be ensured. And the selectivity of treating wounds is poor, and the flexible application of the wound treatment device for wounds of different shapes and sizes cannot be realized due to the electrode structure.
4) The self-regulation can not be carried out according to different requirements, and the intensity of the generated plasma can not be regulated.
Based on the above, the invention designs a portable rechargeable plasma sterilization pen to solve the above mentioned problems.
