[0002] Skin introduction therapy is a treatment method that introduces drugs or nutrients into the skin to achieve skin treatment effects, thereby improving skin quality and enhancing skin gloss and softness. Traditional skin introduction therapy methods usually use microneedles, electroporation or chemical transdermal techniques to form perforations in the skin to introduce drugs or nutrients into the skin. However, these methods may cause skin trauma, pain to the patient or low introduction efficiency.

[0043] Please also read Figures 1 to 5 Now, the plasma skin treatment device provided in an embodiment of the present invention is described.

[0044] Reference Figures 1 to 3 , a plasma skin treatment device according to an embodiment of the present invention comprises: a plasma emitter 100, a nozzle 200, a refrigerant supply mechanism 300, a fluid supply device 400 and a controller 500;

[0045] The plasma emitter 100 has a plasma emitter head 110 for emitting a plasma column; when the plasma emitter 100 is powered on, a plasma column can be emitted from the plasma emitter head 110 to form a perforation on the skin of the patient. The plasma emitter 100 can be connected to a power source through a wire, and when the plasma emitter 100 is powered on, a plasma column can be emitted. Plasma is the fourth state of matter different from solid, liquid and gas. The plasma column generated by the plasma emitter 100 is an ionized substance with a columnar structure. In the ejection direction L of the plasma column, the plasma column forms a perforated surface on the skin, i.e., a treatment surface. At this time, the treatment surface is also the area to be treated of the patient.

[0046] In the ejection direction L of the plasma column, the projection of the plasma emission head 110 is located within the projection area of ​​the nozzle 200; that is, it is ensured that the ejection area of ​​the nozzle 200 can cover the perforation area of ​​the plasma column, and that the fluid and refrigerant ejected by the nozzle 200 can cover the treatment area. The nozzle 200 can be made of an atomizing nozzle, or an air pump can be used to provide an inert gas, so that the nozzle 200 can atomize the refrigerant and the fluid to spray the atomized spray to the treatment area.

[0047] The refrigerant supply mechanism 300 is used to provide refrigerant. The refrigerant supply mechanism 300 has a refrigerant output end 310, and the refrigerant output end 310 is connected to the nozzle 200; that is, the refrigerant supply mechanism 300 is used to provide refrigerant to the nozzle 200 so that the nozzle 200 sprays the refrigerant onto the skin of the patient. The refrigerant can lower the temperature of the patient's skin, so that the patient's skin maintains a cool feeling.

[0048] The fluid supplier 400 is used to provide fluid, and the fluid supplier 400 has a fluid output end 410, and the fluid output end 410 is connected to the nozzle 200; the controller 500 is connected to the plasma emitter 100, the nozzle 200, the refrigerant supply mechanism 300, and the fluid supplier 400 by signal; the controller 500 is at least used to control the action execution of the fluid supplier 400 and the nozzle 200. The controller 500 can be an MCU control board, and the controller 500 is configured to: after the plasma emitter 100 performs plasma perforation, control the fluid and the refrigerant to be delivered to the nozzle 200 and ejected. The controller 500 can transmit signals to the plasma emitter 100, the nozzle 200, the refrigerant supply mechanism 300, and the fluid supplier 400 through electrical signals, Wi-Fi signals, Bluetooth signals, etc., so as to control the plasma emitter 100, the nozzle 200, the refrigerant supply mechanism 300, and the fluid supplier 400 to perform corresponding actions.

[0049] The fluid delivered by the fluid supplier 400 may be liquid medicine, nutrients, or active substances, etc. Under the control of the controller 500, the liquid medicine, nutrients, or active substances are delivered to the nozzle 200 through the fluid supplier 400, and sprayed to the treatment surface through the nozzle 200, so that the liquid medicine, nutrients, or active substances fall into the area where the perforations are located, and are introduced into the interior of the skin through the perforations formed by the plasma column.

[0050] That is, when in use, the plasma emitter 100 is first turned on and powered on, and a plasma column is emitted to the area to be treated of the patient's skin, so that tiny perforations are generated in the area to be treated. The controller 500 controls the actions of the fluid supplier 400 and the refrigerant supply mechanism 300. Then, after the plasma emitter 100 performs plasma perforation treatment, the plasma emitter 100 is disconnected from the power supply, and the plasma emitter 100 stops emitting the plasma column. The controller 500 controls the fluid supplier 400 and the refrigerant supply mechanism 300 to provide the nozzle 200 with refrigerant and fluid, and the nozzle 200 sprays the fluid and refrigerant onto the skin together, so that the medicine or nutrients can be sprayed onto the treatment surface that has been perforated by the plasma column, ensuring that the active ingredients of the medicine or nutrients can penetrate into the skin and improve the absorption efficiency of the active ingredients. In addition, the refrigerant can lower the temperature of the treatment surface, so that the skin during treatment keeps a cool feeling and reduces operational discomfort. Compared with traditional perforation introduction methods such as microneedles or electroporation, plasma perforation treatment can reduce trauma to the patient's skin tissue, reduce the patient's pain during treatment, and improve the convenience and acceptability of skin introduction treatment.

[0051] It should be noted that the refrigerant provided by the refrigerant supply mechanism 300 can be a cooling spray, or it can be a refrigerant such as a low-temperature inert gas that is harmless to the human body and easy to lower the temperature; so as to take away the temperature of the treatment area and keep the skin of the patient feeling cool.

[0052] In some embodiments of the present invention, reference Figures 1 to 3 The plasma skin treatment device further comprises a treatment seat 120, wherein the treatment seat 120 has a mixing chamber, the nozzle 200 is disposed on the treatment seat 120, and the refrigerant output end 310 and the fluid output end 410 are connected to the nozzle 200 through the mixing chamber. The refrigerant and the fluid are fully mixed in the mixing chamber, so that when sprayed, the refrigerant and the fluid can be uniformly sprayed to the treatment area under the drive of the nozzle 200, so as to uniformly cool the treatment area of ​​the skin, avoid the situation where the local skin temperature is too low, or the fluid spraying is uneven, resulting in insufficient treatment.

[0053] In some embodiments of the present invention, reference Figures 1 to 3 , the treatment seat 120 is provided with a plasma ejection hole 130, the plasma emission head 110 is located in the plasma ejection hole 130, and the nozzle 200 is arranged around the plasma ejection hole 130, then the projection area of ​​the nozzle 200 in the ejection direction of the plasma column must be larger than the projection area of ​​the plasma emission head 110, and the nozzle 200 can also be distributed around the plasma emission head 110, so that the fluid and refrigerant ejected by the nozzle 200 are evenly distributed in the treatment area. That is, the plasma emission head 110 can ensure that the plasma column is emitted within the projection range of the plasma ejection hole 130, so as to better set the position of the nozzle 200 on the treatment seat 120, so that the fluid and refrigerant ejected by the nozzle 200 can be more accurately aimed at the treatment area of ​​the finger skin, ensuring the treatment effect.

[0054] In some embodiments of the present invention, reference Figures 1 to 3 The nozzle 200 has a plurality of nozzles 210, and the plurality of nozzles 210 are distributed around the plasma ejection hole 130. The plurality of nozzles 210 can eject refrigerant and fluid, and the plurality of nozzles 210 are distributed around the plasma ejection hole 130, so that the refrigerant and fluid ejected by the nozzle 200 can be sprayed toward the treatment area after the plasma column is perforated, ensuring the treatment effect and the cooling effect. It should be noted that the number of nozzles 210 can be adjusted according to the actual use situation. When the treatment area is small, it can also be set to one nozzle 210 or two nozzles 210 to adapt to the size of the specific treatment area.

[0055] In some embodiments of the present invention, reference Figures 1 to 3The plurality of nozzles 210 are all arranged toward the ejection direction L of the plasma column. The ejection direction L of the plasma column is parallel to the ejection direction of the plasma column of the plasma emitter 100, so that the ejection direction of the nozzles 210 is parallel to the ejection direction of the plasma column of the plasma emitter 100, so that the ejected refrigerant and fluid can better reach the treatment area perforated by the plasma column.

The seat body 121 is a component for supporting the spray head 200 and the support part 122. When the abutting end 123 contacts the skin of the patient, a gap is ensured between the spray end and the skin, which does not affect the spray head 200 from spraying fluid and refrigerant, and can keep a constant distance between the spray end and the skin, so that the treatment effect is stable. In addition, the connection side of the seat body 121 of the treatment seat 120 can also be covered with a cover plate 126.

That is, the support portion 122 is composed of a plurality of support columns 124, and the lengths of the plurality of support columns 124 are the same, so that the spray direction of the spray end can face the skin for better treatment. The support columns 124 are evenly distributed on the periphery of the nozzle 200, so that the treatment seat 120 is better supported on the skin and the force is more evenly applied. In addition, the support portion 122 can be a support table or a support block, etc., which can be arranged according to actual conditions.

The user can select support columns 124 of different lengths for use according to the specific treatment area and treatment effect. In addition, the support column 124 can also be integrally formed with the seat body 121 of the treatment seat 120, or can be bonded together with an adhesive such as glue.

[0059] In some embodiments of the present invention, reference Figures 1 to 3 The refrigerant supply mechanism 300 includes a refrigerant delivery pipe 320 and a control valve 330; the control valve 330 is arranged on the refrigerant delivery pipe 320, and the refrigerant output end 310 is located at the output port of the refrigerant delivery pipe 320; the control valve 330 is connected to the controller 500 by signal.

The plasma launch head 110 is set on the ceramic rod. When the ceramic rod is energized, a plasma column can be generated to be emitted from the plasma launch head 110; wherein the shell includes a first shell 140 and a second shell 150, the first shell 140 and the second shell 150 are used to cover an end of the ceramic rod away from the plasma launch head 110, so that the conductive ceramic rod is connected to the power supply through a wire, and can also prevent users from accidentally touching it.

[0066] When the plasma skin treatment device is in use, the control switch 600 can be pressed, and the controller 500 controls the plasma emitter 100 to start, and the plasma emission head 110 of the plasma emitter 100 emits a plasma column, and the plasma column produces a tiny perforation in the treatment area of ​​the skin of the patient; after a preset time or after the press switch is pressed again, the plasma emission head 110 of the plasma emitter 100 stops emitting the plasma column, and the controller 500 starts the refrigerant supply mechanism 300 and the fluid supply device 400, that is, opens the control valve 330, so that the refrigerant can be input into the nozzle 200 through the refrigerant delivery pipe 320, and the driving motor 446 rotates to drive the piston rod 430 to move, and gradually reduces the input cavity, so that the fluid is also input into the nozzle 200, and the nozzle 200 sprays the fluid and the refrigerant from the nozzle 210 to the skin treatment area after the perforation, thereby ensuring that the active ingredients of the medicine or nutrients can penetrate into the skin and improve the absorption efficiency of the active ingredients. In addition, the refrigerant can reduce the temperature of the treatment surface, so that the skin during treatment keeps a cool feeling and reduces the discomfort of operation.

[0067] Based on the aforementioned plasma skin treatment device, this embodiment further provides a control method of the plasma skin treatment device, which is applicable to the aforementioned plasma skin treatment device, and the control method includes:

[0068] Controlling the plasma emitter 100 to perform plasma perforation;

[0069] After the plasma emitter 100 performs plasma perforation, the fluid and the refrigerant are controlled to be transported to the shower head 200 and sprayed out.

[0070] Based on the aforementioned control method, when the plasma skin treatment device performs skin treatment on a patient, the plasma emission head 110 of the plasma emitter 100 can be first aligned with the treatment area of ​​the patient, and then the controller 500 controls the plasma emitter 100 to perform plasma perforation. After the plasma emitter 100 performs plasma perforation, the fluid and the refrigerant are controlled to be transported to the nozzle 200 and sprayed out, and the fluid and the refrigerant can be sprayed to the perforated treatment area, so that the medicine or nutrients can be sprayed to the perforated treatment area, ensuring that the active ingredients of the medicine or nutrients can penetrate into the skin and improve the absorption efficiency of the active ingredients. In addition, the refrigerant can lower the temperature of the treatment surface, so that the skin during treatment maintains a cool feeling and reduces operational discomfort.

[0071] In summary, the plasma skin treatment device and control method thereof provided by the present invention have at least the following beneficial effects:

[0072] The plasma emitter head 110 of the plasma emitter 100 can generate a plasma column to be emitted to the skin of the patient to produce tiny perforations. Subsequently, the refrigerant supply mechanism 300 and the fluid supply device 400 are started by the controller 500, so that the fluid and the refrigerant are both input to the nozzle 200. The nozzle 200 sprays the fluid and the refrigerant to the skin treatment area after the perforation, thereby ensuring that the active ingredients of the medicine or nutrients can penetrate into the skin and improve the absorption efficiency of the active ingredients. The refrigerant is also used to reduce the temperature of the patient's skin, so that the skin during treatment remains cool and the discomfort caused by the operation is reduced. Compared with the traditional perforation introduction method of microneedles or electroporation, the plasma perforation treatment method can reduce the trauma to the patient's skin tissue, reduce the pain of the patient during treatment, and improve the convenience and acceptability of skin introduction treatment.

[0073] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
