Description

Micro needle apparatus

The present invention relates to a microneedle device, and more particularly, to a microneedle device capable of inducing natural wound healing of the skin and allowing an active ingredient to penetrate into the skin using the microneedle.

In general, the skin is composed of an external epidermis and an internal dermis, and the epidermis may be composed of a transparent layer, a stratum corneum, a moisture barrier, and the like, and the dermis may be composed of a subcutaneous fat layer and the like.

Various drugs or cosmetics for penetrating into the skin to obtain an effective effect may be wasted without being absorbed into the skin by even 1% of the active ingredient in the usual way of spreading or tapping by hand due to the moisture barrier of the granular layer of the skin.

The average thickness of the epidermis of the face is 0.15 mm, which is about 0.2 mm. Since this microneedle opens about 150,000 to 200,000 new transport channels to the dermis layer of the skin, it can penetrate 40 times or more of the enormous amount of active ingredients.

The keratinization cycle of the skin is gradually lengthened from 4 weeks due to natural aging, and microneedle therapy may be required for rapid regeneration of these skin cells.

Unlike other laser treatments that artificially damage skin cells, microneedle therapy uses a fine natural wound healing action and has few side effects.

The conventional microneedle device has a structure in which a microneedle is installed at the tip and a separate container part inside is installed so that the active ingredient flows from the container part to the microneedle, and the user pours or injects the active ingredient into the container part. After filling in this way, it could be used by tapping or rubbing the skin.

However, in such a conventional microneedle device, stepwise control or fine control of the discharge amount of the flowing out active ingredient is impossible, for example, when the viscosity or cohesive force of the active ingredient is too high, the active ingredient does not flow out, so If the active ingredient is not supplied or, conversely, when the viscosity or cohesive force of the active ingredient is too low, the active ingredient flows out too much and is wasted.

In addition, the conventional microneedle device is inconvenient to use because the active ingredient filling process is cumbersome because the existing ampoule container cannot be used and the active ingredient has to be subdivided inside the dedicated container.

In addition, the conventional microneedle device has problems in that it is too short or long because it uses a single body, and thus has a poor grip, and cannot be used by replacing it with various lengths according to users.

The present invention enables step-by-step control or fine control of the discharge amount of the active ingredient flowing out using the discharge amount control device, so that when the viscosity or cohesive force of the active ingredient is too high, the discharge amount is increased or the viscosity or cohesive force of the active ingredient is too high In the low case, it is possible to discharge an appropriate amount according to various types of active ingredients by reducing the amount of discharge, and since the existing ampoule container can be stored inside and used as it is, there is no need for a separate active ingredient filling process. It is intended to provide a microneedle device that can provide an appropriate grip according to various users because it can be conveniently done, and the body can be divided into two parts and used by replacing it with an appropriate length suitable for the user. However, these problems are exemplary, and the scope of the present invention is not limited thereto.

A microneedle device according to the spirit of the present invention for solving the above problems, the body portion is formed with an accommodating space to accommodate the ampoule therein; a needle head installed at the tip of the body; an active ingredient supply pipe connected to the ampoule so as to transfer the active ingredient contained in the ampoule to the needle head part, and extending to the needle head part; and a discharge amount adjusting device capable of controlling the degree of opening of the active ingredient supply pipe so as to adjust the discharge amount of the active ingredient.

In addition, according to the present invention, the needle head portion, a screw rotational head in which a female screw portion is formed so that the screw can be moved forward and backward based on the body portion; a plurality of microneedles formed at the tip of the screw-rotating head; and a through-hole formed to penetrate the screw rotatable head so that the active ingredient discharged through the active ingredient supply pipe is delivered to the micro-needle.

In addition, according to the present invention, the discharge amount adjusting device is formed on the central axis of rotation of the needle head part, and is partially inserted into the opening of the active ingredient supply pipe when the needle head part is screwed forward and backward, and the discharge amount is adjusted according to the degree of insertion It may include; a valve body that is formed in a conical shape as a whole.

In addition, according to the present invention, the discharge amount regulating device is installed between the stepped portion formed in the valve body and the land portion formed at the tip of the active ingredient supply pipe so that the opening can be completely closed when the valve body is screwed backward. It may further include a first O-ring member.

In addition, according to the present invention, the land portion may be formed with an inclined surface whose inner diameter is widened toward the tip so that the width of the land portion is expanded when it comes into contact with the first O-ring member and the degree of adhesion in the outer diameter direction can be improved.

In addition, according to the present invention, the body portion, the male screw portion is formed to be screwed with the female screw portion of the screw rotation head, and the female screw portion to prevent leakage of the active ingredient when the screw rotation of the screw rotation head A second O-ring member may be installed between the male screw parts.

In addition, according to the present invention, the body portion, the tip body is screwed with the needle head portion, a support tube is formed to support the active ingredient supply tube; and a rear end body detachably coupled to the front end body to mount the ampoule in the receiving space.

In addition, according to the present invention, at least one scale or display device indicating the discharge amount may be formed on the surface of the body portion or the discharge amount adjusting device.

In addition, according to the present invention, the active ingredient supply pipe may be made of a soft material having a shape corresponding to the ampoule so as to be interlocked with the inlet portion of the ampoule at the rear end.

According to an embodiment of the present invention made as described above, various causes such as wrinkles and pigmentation and wounds due to aging are fundamentally reduced by inducing collagen production using natural wound healing action and maximizing the skin permeability of active ingredients. Not only can it be improved, but it also enables step-by-step or fine adjustment of the discharge amount of the active ingredient flowing out using the discharge amount control device, so if the viscosity or cohesive force of the active ingredient is too high, increase the discharge amount or If the viscosity or cohesive force is too low, an appropriate amount can be discharged according to various types of active ingredients by reducing the discharge amount or by a separate active ingredient filling process because the existing ampoule container can be stored inside and used as it is. This is unnecessary, so it can be used conveniently, and since the body can be divided into two parts and used by replacing it with an appropriate length suitable for the user, it has the effect of providing an appropriate and optimal grip according to various users. Of course, the scope of the present invention is not limited by these effects.
