Description

Technical Field

[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.

[0044] Please also read Figures 1 to 5 Now, the plasma skin treatment device provided in an embodiment of the present invention is described.

[0045] Reference Figures 1 to 3 The plasma skin treatment device according to the embodiment of the present invention comprises: a plasma emitter 100, a nozzle 200, an inert gas supply mechanism 300, a fluid supply device 400, a refrigeration coil 500 and a controller 600;

[0046] 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.

[0047] 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 cooling system ejected by the nozzle 200 can cover the treatment area. The nozzle 200 can be made of an atomizing nozzle, so that the nozzle 200 can atomize the fluid to spray the atomized spray to the treatment area.

[0048] The inert gas supply mechanism 300 is used to provide an inert gas. The inert gas supply mechanism 300 has an inert gas output terminal 310, and the inert gas output terminal 310 is connected to the nozzle 200. The inert gas supply mechanism 300 is used to provide an inert gas to the nozzle 200. The inert gas can be prepared by nitrogen. The inert gas is input into the nozzle 200. An air pump can be used to apply pressure so that the inert gas serves as an output carrier of the fluid of the nozzle 200, and the fluid is formed into a spray at the nozzle 200 to be sprayed toward the treatment area on the skin of the patient.

[0049] 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;

[0050] The refrigeration circle 500 is used to fit the skin and reduce the temperature of the treatment area of ​​the patient's skin; in the spraying direction of the plasma column, the projections of the nozzle 200 and the plasma emission head 110 are both located within the projection area of ​​the refrigeration circle 500, which can ensure that the fluid sprayed by the nozzle 200 and the plasma column sprayed by the plasma emission head 110 will be sprayed toward the skin area circled by the refrigeration circle 500, so as to treat the skin with reduced temperature, keep the skin cool during treatment, and reduce operational discomfort.

[0051] The controller 600 is signal-connected with the plasma emitter 100, the nozzle 200, the inert gas supply mechanism 300, the fluid supplier 400, and the refrigeration coil 500; the controller 600 is at least used to control the execution of the actions of the fluid supplier 400, the nozzle 200, and the inert gas supply mechanism 300; the controller 600 can be an MCU control board, and the controller 600 is configured to: after the plasma emitter 100 performs plasma perforation, control the fluid and the inert gas to be delivered to the nozzle 200 and ejected.

[0052] The controller 600 can transmit signals to the plasma emitter 100, the nozzle 200, the inert gas supply mechanism 300, the refrigeration coil 500, 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 inert gas supply mechanism 300, the fluid supplier 400, and the refrigeration coil 500 to perform corresponding actions. It should be noted that the nozzle 200 can be opened and closed by a solenoid valve, etc., so as to control whether the nozzle 200 sprays fluid and inert gas.

[0053] The fluid delivered by the fluid supplier 400 may be liquid medicine, nutrients, active substances, etc. Under the control of the controller 600, 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 inside of the skin through the perforations formed by the plasma column.

[0054] Reference Figure 5When in use, the cooling coil 500 is attached to the skin of the patient, and the cooling coil 500 is started, so that the cooling coil 500 cools the encircled skin area to reduce the skin temperature; then the plasma emitter 100 is 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 of the patient, and the controller 600 controls the actions of the fluid supplier 400 and the inert gas 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 The emitter 100 stops emitting the plasma column, and the controller 600 controls the fluid supplier 400 and the inert gas supply mechanism 300 to provide fluid and inert gas to the nozzle 200. The nozzle 200 sprays the fluid in the form of water mist to the skin through the inert gas, so that the medicine or nutrients can be sprayed to 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. The temperature of the treatment surface is reduced by the refrigeration coil 500, so that the skin during treatment remains cool and the discomfort of 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 skin tissue of the treatment, reduce the pain of the treatment during treatment, and improve the convenience and acceptability of skin introduction treatment.

[0055] In some embodiments of the present invention, reference Figures 2 to 4 The plasma skin treatment device further comprises a treatment seat 700; the cooling coil 500 and the nozzle 200 are both arranged on the treatment seat 700, the treatment seat 700 is provided with a first emission through hole 710, the cooling coil 500 is arranged at the periphery of the first emission through hole 710, and the first emission through hole 710 is located in the ring hole of the cooling coil 500; the nozzle 200 is provided with a second emission through hole 210 coaxially arranged with the first emission through hole 710, and the plasma emission head 110 extends into the first emission through hole 710 and the second emission through hole 210. The first emission through hole 710 and the second emission through hole 210 are coaxially arranged, so that the plasma emission head 110 can be directly extended, so that the plasma column emitted by the plasma emission head 110 passes through the treatment seat 700 and reaches the treatment area of ​​the skin of the treated person.

[0056] In some embodiments of the present invention, reference Figures 2 to 4, the nozzle 200 has a plurality of nozzles 220, and the plurality of nozzles 220 are distributed around the second emission through hole 210, and the nozzles 220 are located inside the first emission through hole 710. Each nozzle 220 can spray fluid and inert gas, and the plurality of nozzles 220 are distributed around the second emission through hole 210, so that the sprayed fluid mist can be better sprayed to the spraying area of ​​the plasma column, ensuring that the fluid mist can be evenly sprayed to the treatment area after the plasma column is perforated, ensuring the treatment effect. It should be noted that the number of nozzles 220 can be adjusted according to actual use. When the treatment area is small, it can also be set to one nozzle 220 or two nozzles 220 to adapt to the size of the specific treatment area. Among them, the direction of the nozzle 220 is parallel to the direction of the spray direction L of the plasma column, so as to spray the fluid mist directly to the treatment area.

[0057] In some embodiments of the present invention, reference Figures 2 to 4 The plasma skin treatment device also includes a nozzle seat 800; the nozzle 200 is arranged on the nozzle seat 800, the nozzle seat 800 is connected to the treatment seat 700, and a mixing chamber is arranged inside the nozzle seat 800, and the mixing chamber is connected to the inert gas output end 310 and the fluid output end 410. The nozzle seat 800 is used to carry the nozzle 200, and the treatment seat 700 has a skin side and a connection side that are relatively arranged, wherein the refrigeration coil 500 is arranged on the skin side, and the nozzle seat 800 is located on the connection side to ensure that the refrigeration coil 500 fits the skin, and when the refrigeration coil 500 fits the skin, the nozzle 200 can also have a constant distance with the skin, which does not affect the nozzle 200 from spraying fluid, and ensures a stable treatment effect. In addition, the nozzle 200 can be directly fixed on the treatment seat 700 and is located in the first emission through hole 710 so as to spray fluid mist toward the skin.

[0058] In some embodiments of the present invention, reference Figures 2 to 4 The nozzle seat 800 is provided with a connecting block 810, and the connecting block 810 includes a first joint and a second joint, the first joint is connected to the inert gas output end 310, and the second joint is connected to the fluid output end 410, and the first joint and the second joint are both connected to the mixing chamber. Then, the connecting block 810 is connected to the inert gas output end 310 and the fluid output end 410 through the first joint and the second joint, and the inert gas and the fluid can be transported to the mixing chamber through the first joint and the second joint, so that the inert gas drives the fluid to be ejected from the nozzle 220 of the nozzle 200.

[0059] In some embodiments of the present invention, the refrigeration ring 500 includes a fitting ring portion 510 and a refrigeration sheet 520; the refrigeration sheet 520 has a heat dissipation end and a heat absorption end, the heat dissipation end is in contact with the fitting ring portion 510, and the fitting ring portion 510 is used to fit the skin. The refrigeration sheet 520 is a thermoelectric semiconductor refrigeration component, which can absorb heat at the heat absorption end after being powered on, thereby reducing the temperature of the fitting ring portion 510. Since the fitting ring portion 510 fits the skin, the refrigeration sheet 520 can take away the heat of the skin through the fitting ring portion 510 to reduce the temperature of the skin, so that the skin during treatment remains cool and reduces operational discomfort. The heat dissipation end is where the heat of the refrigeration sheet 520 gathers, and the heat dissipation end is used to dissipate the heat to the surrounding space to ensure that the refrigeration sheet 520 can continue to work.

[0060] In some embodiments of the present invention, reference Figures 3 to 5 , the refrigeration circle 500 also includes a heat exchange head 530, a water inlet pipe 540 and a water outlet pipe 550; the heat dissipation end is in contact with the heat exchange head 530, the water inlet pipe 540 is connected to the water inlet end of the heat exchange head 530, and the water outlet end of the heat exchange head 530 is connected to the water outlet pipe 550. The water inlet pipe 540 is used to enter the cooling water. After the cooling water passes through the heat exchange head 530, it can absorb the heat of the heat dissipation end to reduce the temperature of the heat dissipation end. Then the heat of the cooling plate 520 can be transferred to the water of the heat exchange head 530 through the heat dissipation end, and the water of the heat exchange head 530 will be transported out through the water outlet pipe 550. The heat exchange head 530, the water inlet pipe 540 and the water outlet pipe 550 form a water cooling device to continuously take away the heat for the cooling plate 520, so that the cooling plate 520 can continue to cool, conveniently take away the heat for the skin, so that the skin during treatment keeps a cool feeling and reduces the discomfort of operation. In addition, air-cooling devices such as fans and heat sinks can be used to dissipate heat from the cooling plate 520 to adapt to usage environments where water cooling is not convenient.

The pushing portion 431 abuts against the pushing block 442, and the moving direction of the piston rod 430 is parallel to the moving direction of the pushing portion 431 driven by the linear driving module 441. When the linear driving module 441 drives the pushing block 442 to move, the pushing block 442 drives the pushing portion 431 to move, so that the piston rod 430 moves, so as to reduce the input cavity, so that the fluid in the input cavity can be output to the nozzle 200 through the fluid output end 410, so that the nozzle 200 can spray the fluid.

[0069] 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:

[0070] Controlling the refrigeration loop 500 to perform refrigeration;

[0071] Controlling the plasma emitter 100 to perform plasma perforation;

[0072] After the plasma emitter 100 performs plasma perforation, the fluid and the inert gas are controlled to be delivered to the shower head 200 and ejected.

[0073] Based on the aforementioned control method, when the plasma skin treatment device performs skin treatment on a patient, the refrigeration coil 500 can be started first, and the refrigeration coil 500 cools the skin of the treatment area. Then, the plasma emission head 110 of the plasma emitter 100 is aimed at the skin of the treatment area of ​​the patient. The controller 600 controls the plasma emitter 100 to perform plasma perforation. After the plasma perforation is performed on the plasma emitter 100, the fluid and the inert gas are controlled to be transported to the nozzle 200 and sprayed out. Then, the fluid mist 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 refrigeration coil 500 can reduce the temperature of the treatment surface, so that the skin during treatment maintains a cool feeling and reduces operational discomfort.

[0074] In summary, the plasma skin treatment device and control method thereof provided by the present invention have at least the following beneficial effects:

[0075] The refrigeration coil 500 can cool down the skin area that needs to be treated by the patient, and then the plasma emission head 110 of the plasma emitter 100 can generate a plasma column to be emitted to the skin that needs to be treated, thereby generating tiny perforations in the skin; then the controller 600 is used to start the inert gas supply mechanism 300 and the fluid supply device 400, so that the fluid and the inert gas are both input into the nozzle 200, and the nozzle 200 sprays the fluid and the inert gas together 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, and the refrigeration coil 500 is used to reduce the temperature of the patient's skin, so that the skin during treatment remains cool and the discomfort of 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 patient's pain during treatment, and improve the convenience and acceptability of skin introduction treatment.
