Problems solved by technology

[0002] Most of the currently used epidermal drug treatments cover the surface of the epidermis, but the drug penetration efficiency is low and the effect is limited, thus increasing the treatment time and course of treatment; although the water light needle instrument has the function of injecting into the dermis, its cost is high and requires It takes a long time for professionals to operate and cannot be used conveniently; needle rolling therapy cannot accurately introduce the drug directly to the affected area
[0003] When dermatology or plastic surgery is applied externally to patients, it is often hoped that the drug can be directly penetrated into the dermal tissue for treatment, but because the epidermal cells are dense and cannot pass water-soluble drugs or only partly fat-soluble drugs, it is impossible Achieve satisfactory and efficient treatment

Embodiment 1

[0021] Referring to the accompanying drawings, a microneedle auxiliary material device includes a micro-pressure bag 1 and a liquid medicine bag 2 stacked up and down. The micro-pressure bag 1 is bound to the liquid medicine bag 2 through a binding piece. The size and shape of the bag are suitable for the air bag, one side of the air bag is connected with an air delivery tube 3, and the end of the air delivery tube 3 is connected with a pressurized air source 4, and the pressurization device 4 is a pressurized pinch ball, and the pressurized pinch ball is connected with the delivery tube. An exhaust valve 5 is arranged between the trachea 3; when inflated, the air bag expands in a direction perpendicular to the liquid medicine bag 2; the liquid medicine bag 2 stores liquid medicine, and the lower surface of the liquid medicine bag 2 is vertically connected with a plurality of Hollow microneedles 6 with a length of 2 mm, and a plurality of hollow microneedles 6 are arranged in a...

Embodiment 2

[0023] Compared with embodiment one, the micro-pressure bag 1 in embodiment two is the air bag that internal separation has a plurality of sacs, and each sac is respectively connected to the micro-pressure air pump through an air delivery tube, and the connection between the micro-pressure air pump and the air delivery tube 3 An exhaust valve is arranged between them, and the pressure of the liquid medicine bag 2 can be made more uniform by a plurality of cavities.

[0024] When in use, paste the liquid medicine bag 2 on the affected area, and the needle tip of the hollow microneedle 6 penetrates into the skin. When no pressure is applied, the hollow microneedle 6 will not flow out the liquid medicine. Squeeze and pressurize the ball or turn on the micro-pressure air pump to increase the micro-pressure The pressure in the bag squeezes out the liquid medicine in the liquid medicine bag, and injects the substance into the dermis through the needle tip.

Abstract

The invention discloses a micro-needle auxiliary material device. The device comprises a liquid medicine bag containing liquid medicine, the liquid medicine bag is in a sheet shape, the face, facing the human body, of the liquid medicine bag serves as the front face, a micro-pressure bag is bound to the back face of the liquid medicine bag through a binding piece, a plurality of hollow micro-needles are arranged on the front face of the liquid medicine bag, and the hollow micro-needles are communicated with the liquid medicine in the liquid bag; and the shape of the micro-pressure bag fits theliquid medicine bag, the micro-pressure bag is an expandable air bag and is connected with a pressurized air source through an air delivery pipe, and a sticking piece stuck to the skin of a patient is arranged on the liquid medicine bag. The medicine is injected into the dermis through micro-pressurization, so that the treatment area is large, the efficiency is high, the cost is low, and the medicine can treat the skin more efficiently and conveniently.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary material device for externally applied medicine on the skin. Background technique [0002] Most of the currently used epidermal drug treatments cover the surface of the epidermis, but the drug penetration efficiency is low and the effect is limited, thus increasing the treatment time and course of treatment; although the water light needle instrument has the function of injecting into the dermis, its cost is high and requires It takes a long time for professionals to operate and it is not convenient for the people to use; the needle rolling treatment cannot accurately introduce the medicine directly to the affected area. [0003] When dermatology or plastic surgery is applied externally to patients, it is often hoped that the drug can be directly penetrated into the dermal tissue for treatment, but because the epidermal cells are dense and cannot pass water-s...
