Description

Micro needle device < RTI ID = 0.0 >

The present invention relates to a microneedle device, and more particularly, to a microneedle device, in which a drug stored in a drug storage container is filled in a drug storage portion of a needle portion for injecting a drug into the skin through needles while moving discontinuously, To a microneedle mechanism.

An immunologically active agent or drug (hereinafter referred to as a " drug ") such as a therapeutic agent or a vaccine is generally injected into the body by oral administration or injection administration. However, in the case of oral administration, many drugs are not absorbed directly into the bloodstream due to the action of digestive enzymes or the like in the gastrointestinal tract and are not fully effective. Drugs such as aspirin can also damage the digestive tract.

In the case of injection administration, the drug is directly injected into the blood stream through the skin or vein. Therefore, the drug can be injected into the bloodstream without being deformed by the digestive enzymes in the digestive tract as in oral administration. However, Or pathogenic infections.

In order to overcome the disadvantages of such oral administration or injection administration, there has recently been actively studied a transdermal administration method in which a drug is administered through a skin into a local tissue or systemic circulation system.

An example of a device using such a transdermal administration method is a micro needle device having a micro needle head provided with a plurality of micro needles. In this microneedle device, the microneedles act to pierce the skin layer including the stratum corneum of the skin physically without causing pain upon administration of the drug. Thus, by the piercing of the skin layer through the microneedles when the drug is administered, the microneedle mechanism can speed up the delivery of the drug supplied through the drug supply unit to the dermal layer of the skin.

However, such a conventional micro needle instrument has a disadvantage in that most of the charged drug is completed by one injection, so that it can not be discontinuously injected with a necessary amount of one micro needle mechanism.

FIG. 1 is a perspective view of a microneedle mechanism according to the present invention, FIG. 2 is an exploded perspective view of a microneedle mechanism according to the present invention, and FIG. 3 is a longitudinal sectional view taken along line A-A of FIG.

1 to 3, the micro needle instrument according to the present invention has a basic structure of a main body 1, a drug storage container 2, a drug injection portion 5, and a needle portion 3.

The main body 1 is in the shape of a syringe bottle having both sides penetrated. The drug storage container 2 is inserted into the rear side of the main body 1, and the needle part 3 is inserted into the front side corresponding to the neck of the syringe bottle And a pushing groove 4 according to the elastic movement of the drug storage container 2 is formed around the rear end. The function of the pushing groove 4 will be described later in detail.

The drug storage container 2 is inserted into the rear surface of the main body 1 in a cylindrical shape and is inserted into the drug injection part 5 at its front side and has a length smaller than the length of the main body 1, Or may be formed as long as the length of the main body 1. In the case of the drug storage container constructed as long as the length of the main body 1 because the drug storage container 2 is moved from the back to the inside of the main body 1, the pushing action is smoothly performed by the pushing grooves 4 Respectively. The drug storage container 2 is adapted to be capable of recharging the drug, and the recharging of the drug is accomplished through, for example, a plug, such as a cap attached to the back surface of the drug storage container 2.

The drug injection unit 5 includes a cap unit 11 coupled to the front surface of the drug storage container 2 and a drug injection pipe 12 connected to the center of the drug storage container 2 at the center of the cap unit 11, And an elastic spring 6 is fastened to the drug injection tube 12 between the locking jaw 13 and the front surface of the drug storage container 2 have. The cap portion 11 serves to prevent the drug contained in the drug storage container 2 from leaking. A drug passage 14 through which the drug passes is formed in the center of the drug injection tube 12. The locking jaw 13 is hooked inside the neck of the neck of the main body 1. The elastic spring 6 is compressed and restored according to the movement of the drug storage container 2, The passage 14 is opened and closed so that the drug can be moved or restricted through the drug passage 14. [ The cap portion 11 serves as a kind of guide for allowing the drug storage container 2 to move straight in the main body 1. [

The needle portion 3 is composed of a needle coupling body 8 to which a microneedle 7 is coupled and a drug receptor 9 connected to the needle coupling body 8. The drug channel 9 formed in the drug receptor 9 And a drug receiving portion 9b is formed on the front side. The needle portion 3 thus configured is inserted and fixed from the drug receptor 9 to the front surface of the main body 1 so that the passage 9a of the drug receptor 9 is inserted into the drug storage container 2, And the needle coupling body 8 to which the microneedle 7 is coupled is protruded out of the front surface of the main body 1. The drug-

A protective cap 10 for covering and protecting the needle portion 3 may be connected to the front surface of the main body 1. [

Hereinafter, a method of using drug injection using the micro needle device of the present invention constructed as described above will be described.

FIG. 4 is a longitudinal sectional view of a microneedle apparatus according to the present invention in use; and FIG. 5 is a longitudinal sectional view of a microneedle apparatus according to an embodiment of the present invention.

First, the microneedle device of the present invention shown in Fig. 4 is in a state in which the drug storage container 2 is filled with a drug, and this state is before the drug storage container 2 is used.

5, when the rear surface of the drug storage container 2 is pressed with the fingers in the state before use as described above, the latching jaw 13 is hooked on the front side of the main body 1 and the elastic spring 6 is compressed, The drug storage container 2 elastically advances and moves inside the front surface of the main body 1 so that the drug injection tube 12 of the drug injection portion 5 coupled to the drug storage container 2 is inserted into the needle portion 3 ) ≪ / RTI > of the drug receptor (9). When the drug storage container 2 is elastically moved and the drug passage 14 of the drug injection tube 12 of the drug injection part 5 on the front side is opened while the drug storage container 9 is moved through the passage 9a of the needle part 3 A portion of the drug in the drug storage container 2 moves into the drug storage portion 9b formed in the drug storage container 2. Here, the pressing groove 4 is formed to prevent the rear end of the main body 1 from being interfered with when the back of the drug storage container 2 having a long length is pressed with a finger as described above.

When a part of the drug is moved into the drug storage part 9b and then the operation of pressing the back surface of the drug storage container 2 is released, the drug storage container 2, which has been advanced by the recovery of the compressed elastic spring 6, The main body 2 is elastically retreated to the rear side of the main body 1 and moves so that the drug passage 14 of the drug injection tube 12 of the drug injection portion 5 is closed.

Next, in the state where a certain amount of medicine is filled in the drug storage portion 9b of the rear drug storage container 9, the micro needle 7 is pushed into the skin to exhaust the medicine filled in the drug storage portion 9b.

In this way, when it is necessary to push the rear surface of the drug storage container 2 by the necessary amount of medicine to move into the drug storage portion 9b of the needle portion 3 and fill it and then inject it into the necessary place using the micro needle 7 .

When the drug in the drug storage container 2 is used up, the drug may be stored again after opening the cover on the back surface, and the drug may be continuously used in the same manner as described above.
