Description

Technical Field

[0001] This utility model relates to the field of plasma technology, and in particular to a plasma activation device. Background Technology

[0002] Regularly cleaning hands with alcohol-based hand sanitizers or soap and water is cited by the World Health Organization (WHO) as "one of the most important hygiene measures to prevent the spread of viral infections." Many national Centers for Disease Control and Prevention (CDCs) have reiterated this statement to reduce the spread of viral infections and other infectious pathogens. Hands are one of the most common routes of transmission for many infections because they come into direct contact with known pathogens and enter through the mouth, nose, and eyes. Hand sanitizers are used to prevent the spread of infections primarily transmitted through hands, leading to various illnesses such as hospital-acquired foodborne illnesses.

[0003] Recent advances in plasma technology have led to the generation of cold plasmas containing ions / heavy particles at near-room temperature, which has enormous potential applications in biomedical engineering. The efficacy of cold plasmas can be attributed to the following components: electrons, charged particles, reactive oxygen species (ROS), reactive nitrogen species (RNS), free radicals, ultraviolet (UV) photons, molecules, electromagnetic fields, physical forces, and electrical fields. Cold plasmas have been applied in sterilization, wound healing, blood clotting, dermatology, dental treatment, cancer treatment, and immunotherapy. However, current plasma activation devices are bulky, inconvenient to carry, and have low safety standards. Utility Model Content

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] The Centers for Disease Control and Prevention (CDC) recommends strict and regular use of soap and water to maintain proper hand hygiene. They also recommend the use of alcohol-based hand sanitizers: gels, wipes, and sprays, when soap and water are unavailable and hands are not visibly dirty. Alcohol-based gel hand sanitizers have been successfully commercialized for the healthcare and consumer markets. See US Patents: US9161982B2 and US 8562907B2. However, for the disinfectant to be effective, the ethanol concentration must be at least 60%, which makes it flammable. Accidental ingestion could lead to poisoning similar to intoxication. Furthermore, alcohol-based disinfectants may cause dry and irritated skin.

[0026] Meanwhile, cold plasma, with its room temperature and normal atmospheric pressure, has a wide range of groundbreaking biomedical applications. Cold plasma can effectively kill viruses, bacteria, yeasts, molds, and other harmful microorganisms that are difficult to inactivate using traditional methods. The unique physical and chemical properties of plasma enable medical applications, including sterilization processes. See Chinese Patent: CN101284142B. Furthermore, the reactive substances and ultraviolet photons generated by plasma have bactericidal effects. The unique feature of plasma is its ability to discharge in different modes and form coherent structures, thus allowing for instantaneous modulation of electric fields, reactive substances, and charged particles.

[0027] However, in the existing technology, the plasma activation device 10 is large in size, inconvenient to carry, and has low safety.

[0028] In view of the above shortcomings, this utility model proposes a plasma activation device 10, the specific solution of which is as follows: Please refer to Figure 1 , 2As shown, in some embodiments, a plasma activation device 10 includes a water reservoir 110, an atomizer 120, a mixing chamber 130, an ionization channel 180, a plasma liquid storage tank 220, and an outlet 160. The atomizer 120 is connected to the water reservoir 110 and is used to generate atomized gas. The mixing chamber 130 is connected to the atomizer 120, and the atomized gas enters into the mixing chamber 130. One end of the ionization channel 180 is connected to the mixing chamber 130, and the other end is connected to the outside. An ionization device is provided in the ionization channel 180, and the outside air is ionized by the ionization device to generate plasma. The plasma enters the mixing chamber 130 and mixes with the atomized gas. The plasma liquid storage tank 220 is connected to the mixing chamber 130. The outlet 160 is connected to the plasma liquid storage tank 220.

[0029] It is understandable that the aforementioned ionization device is a room-temperature plasma ionization device, which is a common and existing type of device. Specifically, a room-temperature plasma ionization device is a special device capable of generating non-thermal equilibrium plasma. Its core principle is to ionize gas molecules using a radio frequency or microwave electric field. Such devices typically consist of electrode assemblies, gas channels, and a cooling system. The electrodes employ a multi-layered or split design (such as a combination of an anode and a surrounding cathode). A high-frequency electric field accelerates electrons, causing them to collide with neutral gas molecules, thereby generating high-energy electrons, ions, and excited-state active particles. The device often includes auxiliary gas interfaces and diffusion components to optimize gas distribution and ionization efficiency.

[0030] It is understood that the plasma activation device 10 of this invention can be a plasma hand sanitizer dispenser to provide an application for hand disinfection.

[0031] It is understandable that the atomizer 120 can be an evaporation device, that is, using heating to vaporize water into water vapor.

[0032] This novel plasma hand sanitizer dispenser offers a simpler, one-step solution to replace other alcohol-based hand sanitizers. The device also boasts a long lifespan and requires only air, water, and electricity to generate the disinfectant solution. Water can be obtained from a tap, bottle, or any purified source. This plasma hand sanitizer dispenser, incorporating plasma technology, promises to revolutionize the concepts of hand disinfection, wound healing, and skin disease management.

[0033] Understandably, outlet 160 could be a nozzle used to eject plasma liquid.

[0034] In some embodiments, the plasma activation device 10 further includes a condensation device connected between the mixing chamber 130 and the plasma liquid reservoir 220 to condense the atomized gas discharged from the mixing chamber 130 to the plasma liquid reservoir 220.

[0035] It is understandable that a condenser can be used to cool the atomized gas into a liquid.

[0036] In some embodiments, the plasma activation device 10 further includes an ion fluid recovery component connected between the plasma fluid storage 220 and the water storage 110. When the volume of plasma fluid in the plasma fluid storage 220 reaches a threshold, the excess plasma fluid is recovered by the ion fluid recovery component into the water storage 110.

[0037] In some embodiments, the plasma activation device 10 further includes a plasma liquid collector 210, which is connected between the mixing chamber 130 and the plasma liquid storage tank 220, for temporarily storing the atomized gas mixed with plasma so as to gradually cool it into plasma liquid.

[0038] In some embodiments, the ionized body fluid recovery assembly includes a pump body.

[0039] In some embodiments, the plasma activation device 10 further includes a power supply that powers the plasma activation device 10.

[0040] In some embodiments, the power source includes a storage battery. By using a storage battery, the plasma activation device can be carried more conveniently, especially in places where it is inconvenient to obtain power, such as outdoors.

[0041] Understandably, the power connection has a 170mm power plug.

[0042] In some embodiments, the plasma activation device 10 further includes a controller 150 for controlling the plasma activation device 10.

[0043] In some embodiments, the plasma activation device 10 further includes a sensor 140 located on the same side as the outlet 160, and the sensor 140 is used to sense human body parts.

[0044] In some embodiments, the upper part of the water reservoir 110 is provided with a water inlet 190.

[0045] In some embodiments, the water reservoir 110 is located above the atomizer 120, the mixing chamber 130, the ionization channel 180, and the plasma liquid reservoir 220, and the outlet 160 is located below the plasma liquid reservoir 220, thereby allowing the liquid to be moved by gravity.

[0046] The following describes the usage process of the plasma activation device 10 of this utility model when configured as a plasma handwashing device. Water is added to the water reservoir 110 through the water inlet 190, or water is introduced into the water reservoir 110 through a connecting water pipe. After the power supply is connected and the water is filled, the water in the water reservoir 110 flows to the atomizer 120 and is atomized, then moves to the mixing chamber 130. At the same time, outside air is drawn in through the side of the mixing chamber 130 and ionized into plasma in the ionization channel (e.g., plasma handwashing device 10). Figure 3a , 3b (As shown). The plasma vapor in mixing chamber 130 contains reactive oxygen species (ROS) and reactive nitrogen species (RNS) (as shown). Figure 4 (As shown). The plasma liquid is collected in the plasma liquid collector 210 and injected into the plasma liquid storage tank 220 until it is full. If no one uses the plasma liquid for one hour, 80% of the plasma liquid in the plasma liquid storage tank 220 will be injected into the water tank 110 through the plasma liquid recovery device 230, and a new round of plasma liquid preparation will begin; if more than 80% of the plasma liquid is used, a new round of plasma liquid preparation will also be carried out.

[0047] When hands are placed under the plasma hand sanitizer, sensor 140 is triggered. Controller 150 then activates the plasma hand sanitizer nozzle, spraying plasma liquid from plasma liquid reservoir 220 onto the hands through the nozzle.

[0048] It is understandable that the plasma liquid generated by the plasma activation device 10 can also be applied to any surface, equipment, instrument (such as medical devices or knives) or any other application requiring hygiene, including medicine, food, agriculture and personal protective equipment, etc.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
