The utility model provides a microneedle therapy head.
In an embodiment of the present utility model, referring to fig. 1 to 9, the microneedle therapy head includes: a housing 10, wherein a microneedle cavity 11 is arranged in the housing 10, and a microneedle 20 is arranged in the microneedle cavity 11;
a microneedle through opening 80, the microneedle through opening 80 being provided on the housing 10, the microneedle through opening 80 being provided corresponding to the microneedle 20;
the refrigerant hole 30, the refrigerant hole 30 and the microneedle through hole 80 are arranged on the same side of the shell 10;
the coolant tube 40, the coolant tube 40 is set in the shell 10, and is used for inputting the coolant which can flow to the coolant hole 30 and the micro needle 20.
When the microneedle therapy head is used, the surface of the microneedle therapy head provided with the microneedle through-hole 80 is abutted against the skin, then the microneedle 20 protrudes out of the microneedle cavity 11 through the microneedle through-hole 80 to penetrate the skin, the microneedle 20 reaches the subcutaneous fat layer, and the microneedle 20 is discharged to destroy the subcutaneous fat cells. The refrigerant hole 30 and the microneedle through hole 80 are arranged on the same side of the shell 10, so that the opening of the refrigerant hole 30 is positioned on the surface of the skin acted by the microneedle 20, and the refrigerant output by the refrigerant hole 30 can directly reach the surface of the heat-generating skin to cool the surface skin. The refrigerant can be low-temperature hydrogen, nitrogen or helium, and the like, and the source of the refrigerant is easy to obtain and store. In general, such refrigerants are stored in a tank, and most of the refrigerants in the tank remain in a liquid state, and when they need to be taken out, they are gasified and output from the refrigerant holes 30. The specific method for taking the refrigerant belongs to the prior art and is not described herein. The micro-needle 20 can generate heat when generating radio frequency current, and the cooling medium flows to the micro-needle 20 to cool the micro-needle, so that skin damage caused by adhesion of the micro-needle to skin due to overhigh temperature is avoided.
Referring to fig. 1 to 4, further, a refrigerant hole 30 is provided on the housing 10, a refrigerant pipe 40 communicates with the micro needle chamber 11, and the refrigerant hole 30 communicates with the micro needle chamber 11. The refrigerant pipe 40 is used for conveying the refrigerant, the refrigerant pipe 40 is communicated with the micro needle cavity 11, the refrigerant can be conveyed into the micro needle cavity 11, the refrigerant hole 30 is also communicated with the micro needle cavity 11, and therefore the refrigerant can be output through the refrigerant hole 30 and acts on the skin to finish the refrigeration of the skin. At the same time, the refrigerant can be output from the microneedle through hole 80 and act on the skin, so that the output position of the refrigerant is increased, and the refrigerating effect is improved. In addition, since the refrigerant is introduced into the microneedle cavity 11, the microneedle 20 can be refrigerated, the microneedle 20 can not avoid heating during operation, and when the temperature of the substances is different, the resistances are different, so that the stability of the temperature of the microneedle 20 is maintained, the magnitude of the current generated by the microneedle 20 is controlled, the action efficiency of the microneedle 20 on the adipocytes is controlled accurately, and the treatment accuracy is improved. Since the micro-needle 20 is installed in the micro-needle cavity 11, the refrigerant can flow to the micro-needle 20 when being conveyed into the micro-needle cavity 11, thereby realizing refrigeration of the micro-needle 20.
Referring to fig. 5 to 7, further, the housing 10 includes a body and an upper cover 60, the microneedle cavity 11 is disposed in the body, the upper cover 60 is disposed on the body, and a refrigerant cavity 70 is formed between the upper cover 60 and the body; the microneedle through hole 80 comprises a first through hole 81 formed in the housing 10 and a second through hole 82 formed in the upper cover 60 and opposite to the first through hole 81; the refrigerant hole 30 is provided in the upper cover 60, and the refrigerant pipe 40 communicates with the refrigerant chamber 70. The refrigerant cavity 70 reduces the distance that the refrigerant needs to travel to act on the skin, and the refrigerant only needs to pass through the refrigerant cavity 70 and then be directly output from the refrigerant hole 30. In addition, the volume of the cooling medium chamber 70 can be smaller, so as to avoid the temperature rise caused by cooling medium dispersion, or escape as a microneedle therapy head without acting on the skin. Since the micro-needles 20 need to pass through the coolant cavity 70 before passing through the upper cover 60 and finally acting on the skin in use, the coolant can contact the micro-needles 20 and cool the micro-needles 20 when being delivered to the coolant cavity 70.
Referring to fig. 5 to 7, the upper cover 60 is optionally detachably connected with the body. Because the upper cover 60 is in direct contact with the skin, the upper cover 60 is worn and damaged easily, and the detachable connection can enable the upper cover 60 to be replaced easily. In addition, the material of the upper cover 60 may be a heat-conducting material, such as aluminum, stainless steel, or titanium, and the refrigerant must pass through the upper cover 60 before acting on the skin, so that the upper cover 60 may be cooled, and the upper cover 60 may conduct the part of the refrigerating effect to the skin, thereby improving the refrigerating effect. The detachable connection can be a snap connection or a screw connection.
