DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The purpose of the present invention is to provide a plasma therapy device to solve the problems existing in the above-mentioned prior art, make the plasma therapy device compact in structure, and improve the convenience and adaptability of the plasma therapy device.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] The present invention provides a plasma therapy device, comprising a housing 1, a power supply 3 and an electrode head 2, as shown in Figure 1. The power supply 3 is arranged in the housing 1, and the electrode head 2 includes a gas tube 4 and a protective nozzle 5. The gas tube 4 is filled with a rare gas, one end of the gas tube 4 extends into the housing 1 and is connected to the power supply 3, and the protective nozzle 5 is sleeved on the end of the gas tube 4 extending outside the housing 1 and is connected to the housing 1, and the protective nozzle 5 is arranged to protrude from the gas tube 4; when the electrode head 2 is placed in a treatment area, the protective nozzle 5 contacts the treatment area, and the working space enclosed by the gas tube 4, the protective nozzle 5 and the treatment area is connected to the external environment.

[0033] The plasma therapy device of the present invention operates by placing the electrode head 2 in the treatment area, contacting the protective nozzle 5 with the treatment area, and connecting the power supply 3. The noble gas in the gas tube 4 acts as a triggering medium, ionizing the air in the working space enclosed by the gas tube 4, the protective nozzle 5, and the treatment area, generating plasma. The plasma acts on the treatment area to treat the treatment area. The present invention provides a protective nozzle 5 that protrudes from the gas tube 4 to provide protection for the treatment area. By changing the operating parameters of the power supply 3, the operating state of the therapy device can be adjusted, forming a uniform plasma cloud in the treatment area, achieving treatment without damaging surrounding normal tissue. The plasma therapy device of the present invention has a power supply 3 disposed within a housing 1, and the electrode head 2 is fixed to the housing 1. The overall structure of the therapy device is compact, and the integrated structure greatly improves the convenience of operation and portability, and enhances the flexibility and adaptability of the therapy device.

[0034] Among them, the electrode head 2 also includes a conductive lead ring 6, which is mounted on the outside of the gas tube 4 and electrically connected to the power supply 3. The electrode head 2 is connected to the power supply 3 using the conductive lead ring 6, which facilitates the layout and connection of various components in the shell 1, is conducive to the rational use of the space in the shell 1, and further improves the compactness of the structure of the therapeutic device.

[0035] In practical applications, the conductive lead ring 6 can be made of copper foil tape, which is wrapped around the outside of the conductive lead ring 6 as the conductive lead ring 6, and then the conductive lead ring 6 is connected to the power supply 3 using a wire, saving space inside the shell 1.

[0036] Specifically, referring to FIG3 , the gas tube 4 includes a cylindrical section 401 and a truncated cone section 402, which are connected. The cylindrical section 401 extends from the housing 1, which is conducive to increasing the working space surrounded by the gas tube 4, the protective nozzle 5, and the treatment area. The protective nozzle 5 is mounted on the cylindrical section 401 and is also connected to the housing 1, thereby improving the structural stability of the electrode head 2. In addition, the electrode head 2 also includes a support frame 7, which is arranged in the housing 1. The support frame 7 has a support groove that is compatible with the gas tube 4. The gas tube 4 is arranged in the support groove. The support frame 7 provides support and positioning for the gas tube 4 and the conductive lead ring 6, thereby improving the structural stability of the electrode head 2. It should also be noted that in this specific embodiment, the gas tube 4 is made of glass, and the rare gas in the gas tube 4 can be neon, argon, helium, etc. The present invention uses a gas medium to generate plasma, which can treat human tissue more gently and reduce side effects. In actual application, a suitable gas medium can be selected according to actual treatment needs to improve the flexibility and adaptability of the therapeutic device.

[0037] In order to facilitate the connection between the conductive lead ring 6 and the power supply 3, the support frame 7 has a wire hole 8, which is U-shaped. The wire connected to the conductive lead ring 6 can pass through the wire hole 8 and be connected to the power supply 3, avoiding damage to the wire caused by the support frame 7 and ensuring the normal operation of the therapeutic device.

[0038] The plasma therapeutic device of the present invention further includes a charging base 9, which is detachably connected to the housing 1. The power supply 3 includes a rechargeable battery 10. When the charging base 9 is connected to the housing 1, the charging base 9 and the rechargeable battery 10 are electrically connected. The inclusion of the rechargeable battery 10 in the power supply 3 further facilitates the portability and mobility of the therapeutic device and improves operational convenience. When the therapeutic device needs to be charged, it is only necessary to connect the housing 1 to the charging base 9. The charging base 9 and the housing 1 can be connected in a plug-in manner, which is convenient to operate. It should also be noted that in other specific embodiments of the present invention, the rechargeable battery 10 can be a lithium battery, which improves the safety factor of the power supply 3 and extends the battery life of the therapeutic device. The power supply 3 also includes a protective plate 11, which is fixed in the housing 1. The rechargeable battery 10 can be fixed to the protective plate 11 (see Figure 4 for details), which improves the structural stability and operational reliability of the power supply 3.

[0039] In addition, the plasma therapeutic device of the present invention further includes a protective cover 12, which is disposed on the outside of the electrode tip 2 and is detachably connected to the housing 1. When the therapeutic device is in use, the protective cover 12 can be removed from the housing 1. After use, the protective cover 12 is replaced on the electrode tip 2, and the protective cover 12 is connected to the housing 1 to prevent external impurities from entering the electrode tip 2 and improve the hygienic factor of the therapeutic device. In actual use, the protective cover 12 can be connected to the housing 1 in a snap-fit ​​manner to facilitate assembly and disassembly operations.

[0040] More specifically, the plasma therapeutic device in this embodiment also includes a controller and a control panel 13. The control panel 13 is embedded in the outer surface of the housing 1. The power supply 3 and the control panel 13 are both connected to the controller. The operator can use the control panel 13 to conveniently control the operating state of the therapeutic device and adjust its operating parameters. The controller is controlled by a PCB circuit board. Setting up the controller is a common method used by those skilled in the art and will not be detailed here.

[0041] When the electrode head 2 is placed in the treatment area, the end face of the protective nozzle 5 contacts the treatment area. Since the treatment area is mostly non-planar, there is a gap between the protective nozzle 5 and the treatment area, allowing air from the external environment to enter the working space. In order to ensure that the working space can be connected to the external environment, in other specific embodiments of the present invention, a U-shaped notch is provided on the side wall of the protective nozzle 5, with the opening of the U-shaped notch facing the side away from the gas tube 4. The working space is connected to the external environment via the U-shaped notch. The size of the U-shaped notch can be reasonably set to allow air from the external environment to enter, while minimizing the leakage of plasma and ensuring the normal operation of the therapeutic device.

[0042] In practical applications, a protrusion and a depression can be provided on the end surface of the protective nozzle 5 protruding from the gas tube 4. The protrusion and depression are arranged around the gas tube 4. The protrusion can contact the treatment area, while the depression cannot, forming a certain gap. The working space is connected to the external environment by utilizing the gap between the depression and the treatment area, thereby improving the operating reliability of the therapeutic device. Similarly, the size of the protrusion and depression can be reasonably set to reduce plasma leakage.

[0043] In the plasma therapy device of the present invention, the power supply 3 is arranged in the shell 1, and the electrode head 2 is fixed on the shell 1. The overall structure of the therapy device is compact, the size is small, and it is easy to carry, which reduces the requirements of the therapy device on the use environment; the plasma is generated by a gas medium, which can treat human tissue more gently and reduce side effects compared with the heat therapy and light therapy in the prior art; in addition, the electrode head 2 of the present invention is provided with a protective nozzle 5, which can provide protection for the treatment area, and a protective cover 12 is provided on the outside of the electrode head 2 to avoid contamination by impurities, thereby improving the hygiene factor of the therapy device.

[0044] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
