Description

Pressurized Medication Dispenser

The present invention relates to a drug dispenser, and more particularly, to a pressurized drug dispenser capable of easily dispensing a drug stored in a vial after firmly attaching related parts to a conventional vial.

Various types of skin treatment methods such as acne treatment, pore reduction, wrinkle removal, and scar removal are currently being attempted by modern people, whose interest in skin care is rapidly increasing.

In general, when a cosmetic or drug is delivered through the skin, it is difficult for the drug to penetrate the stratum corneum, resulting in a very low absorption rate.

In order to improve this, the skin was punctured with a plurality of microneedles to create a passage through which the drug could effectively penetrate the skin, thereby increasing the absorption effect of the drug.

In this conventional method, after filling the inside of a needle module as suggested in Registered Patent No. 10-1929761, the drug permeates into the skin while puncturing the skin with microneedles. There is a cumbersome problem because you have to go through the process of filling it.

The present invention was made to solve the problems of the prior art, and it is possible to use the vial as it is without changing or modifying the design of the conventional vial to facilitate the dispensing of the drug, and even if there is a tolerance between the parts, the vial Its purpose is to provide a pressurized drug dispenser that can firmly install parts on.

A pressurized drug dispenser according to the present invention for solving the above problems includes a vial in which a drug is stored; a pressurized discharge unit made of an elastic material installed at the inlet of the vial; A needle cap inserted and fixed to the end of the pressurized discharge unit, provided with a plurality of microneedles, and having a drug discharge hole formed between the microneedles to discharge the drug supplied from the vial when the pressurized discharge unit is pressed. .

Here, the pressurized discharge unit includes an enclosing unit that elastically tightens the circumference of the inlet of the vial; It consists of; a pressing part extending from the enclosing part, pressed by a user's finger, and having an end portion tightening the circumference of the needle cap with an elastic force.

Also, a pressing button that the user presses with a finger is integrally provided on an outer surface of the pressing unit.

In addition, the pressing part may be formed in the form of a corrugated tube whose length is stretched in the vertical direction.

On the other hand, the pressurized drug dispenser according to the present invention includes a vial in which a drug is stored; a pressurized discharge unit made of an elastic material installed at the inlet of the vial and having a drug discharge hole through which the drug supplied from the vial is discharged; A needle ball that is rotatably installed inside the pressurized discharge unit and has a plurality of microneedles formed on an outer surface to penetrate the skin while finely perforating the skin.

Here, the pressurized discharge unit includes an enclosing unit that elastically tightens the circumference of the inlet of the vial; a pressing portion extended from the enclosing portion and pressed by a user's finger; It is formed by extending from the pressing part, the needle ball is rotatably installed, and the curved seating part in which the drug discharge hole is formed.

And, the diameter of the upper end of the inner circumferential surface of the curved seating part is smaller than the diameter of the needle ball.

The pressurized drug dispenser of the present invention configured as described above has the advantage of being able to easily discharge the drug inside the vial by freely installing or detaching it from the vial used previously by applying pressure. That is, since the drug stored in the vial is discharged by simply pressing the vial, it is easy to discharge the drug.

In addition, since the pressurized discharge unit installed in the vial is made of an elastic material, it can be firmly fixed to the vial only by the elastic force of the pressurized discharge unit, and thus there is no need to use a separate member to secure the pressurized discharge unit to the vial. Likewise, since the pressurized discharge part is made of an elastic material, there is an advantage in that it can respond even if there is a tolerance between parts.

In addition, since the fine needles are formed on the spherical needle ball and the needle ball freely rotates in all directions within the curved surface seating part, even when the needle ball rolls in the vertical direction and then rolls in the horizontal direction or vice versa Since there is no need to change the gripping posture of the drug dispenser, there is an advantage of facilitating the procedure. In addition, since the operator can roll the needle ball while freely changing the direction on the skin of the person being treated, there is an advantage in that the operation time can be reduced.

An annular groove 21a is formed on the inner circumferential surface of the enclosing portion 21 into which the annular projection 11a of the vial 10 is inserted. In other words, when the enclosing portion 21 is slightly opened and then put on the inlet portion 11 of the vial 10, the annular protrusion 11a is inserted into the annular groove 21a, and the enclosing portion ( 21) is in close contact with the outer surface of the inlet portion 11 of the vial 10.

In addition, a plurality of annular ribs 21b may protrude upward and downward on the outer surface of the enclosing portion 21, and the annular ribs 21b prevent the pressurized discharge portion 20 from slipping in the user's hand. do.

The pressing part 22 is a part that the user presses with a finger, and the end part tightens the circumference of the needle cap 30 with an elastic force. That is, when the vial 10 is turned upside down, the drug inside the vial 10 flows into the pressing portion 22 of the pressurized discharge portion 20. The drug is discharged to the skin through the drug discharge hole 32 formed in (30).

As shown in FIGS. 1 to 3 , the pressing part 22 may be integrally provided with a pressing button 22a that the user presses with a finger on the outer surface. Therefore, the user presses the pressing part 22 from the side. When you want to press, you can clearly see where you are pressing with your finger. This pressing button (22a) is formed thicker than other parts of the pressing portion (22).

In addition, the pressing unit 22 may be formed in the form of a corrugated tube whose length expands in the vertical direction as shown in FIGS. 4 to 6 . That is, by configuring the pressing part 22 in the form of a corrugated pipe without forming the pressing button 22a in the pressing part 22, when the pressing force in the vertical direction is applied to the pressing part 22, the length of the pressing part 22 is reduced. While doing so, the drug inside is discharged through the drug discharge hole 32 of the needle cap 30.

When the upper part of the pressing part 22 is slightly opened and the needle cap 30 is pushed therebetween, the inner circumferential surface of the pressing part 22 is brought into close contact with the edge of the needle cap 30 by elastic force, so that the needle cap 30 becomes firm. it is fixed

Meanwhile, the pressurized drug dispenser according to the present invention may be configured as shown in FIGS. 7 to 9 .

The pressurized drug dispenser shown in FIGS. 7 to 9 includes a vial 10, a pressurized discharge unit 20 installed at the inlet 11 of the vial 10, and the inside of the pressurized discharge unit 20. It is configured to include a needle ball 40 that is rotatably installed.

As described above, the vial 10 stores the drug, and an annular projection 11a protrudes from the inlet portion 11.

The pressurized discharge unit 20 has a drug discharge hole 23a through which the drug supplied from the vial 10 is discharged, and is made of an elastic material. Therefore, the pressurized discharge unit 20 has a certain elastic force and can be widened or bent.

The pressurized discharge unit 20 includes an enclosing portion 21, a pressing portion 22 integrally extending from the upper end of the enclosing portion 21, and a curved surface seated integrally extending from the upper end of the pressing portion 22. It consists of part 23.

The enveloping portion 21 tightens the circumference of the inlet portion 11 of the vial 10 with an elastic force. The enclosing portion 21 has an annular groove 21a formed on the inner circumferential surface into which the annular protrusion 11a of the vial 10 is inserted, and a plurality of annular ribs 21b protruding upward and downward on the outer surface thereof.

The pressing portion 22 is a portion that the user presses with a finger, and when the vial 10 is turned upside down, the drug inside the vial 10 flows into the pressing portion 22 . Therefore, when the user presses the pressing portion 22 with a finger, the drug is discharged to the outside through the drug discharge hole 23a formed in the curved surface seating portion 23 .

The curved surface seating portion 23 has a hemispherical shape with an open top and a concave surface concave downward, and a needle ball 40 is inserted into the curved surface seating portion 23 to freely rotate 360 degrees in all directions.

The diameter of the upper end of the inner circumferential surface of the curved seating portion 23 is smaller than that of the needle ball 40 . Therefore, when inserting the needle ball 40 into the curved surface seating portion 23, the open top of the curved surface seating portion 23 must be opened and pushed in, and when the needle ball 40 is inserted into the curved surface seating portion 23 It is restored to its original shape by elasticity. When the needle ball 40 is inserted into the curved seating part 23, a portion of the spherical needle ball 40 comes out, and a portion of the needle ball 40 comes out in contact with the skin of the recipient.

Meanwhile, a drug discharge hole 23a communicating with the inner space of the pressing part 22 is formed on the bottom surface of the curved seating part 23 .

The needle ball 40 freely rotates 360 degrees in all directions within the curved surface mounting portion 23, and a plurality of fine needles 41 are densely protruded on the outer surface to supply from the vial 10 while finely puncturing the skin It acts to penetrate the drug into the skin.

When the microneedle 41 rotates while in contact with the subject's skin, it finely perforates the skin to increase the absorption effect of the drug.

On the other hand, a plurality of curved protrusions 42 protrude from the outer surface of the needle ball 40 .

The curved protrusions 42 are formed protruding one by one on the outer surface of the needle ball 40 between the fine needles 41, and since their height is formed higher than the fine needles 41, the fine needles 41 are seated on the curved surface. It does not come into contact with the inner surface of the portion 23.

Therefore, the curved protrusion 42 is a part in contact with the inner surface of the curved seating portion 23 when the needle ball 40 rotates within the curved seating portion 23, and the needle ball 40 and the curved surface seating portion are in contact with each other. The frictional force between the part 23 is minimized. As friction is minimized in this way, the needle ball 40 can rotate more smoothly.

The present invention relates to a pressurized drug dispenser capable of easily dispensing a drug from a vial in which a drug for improving skin is stored, and can be widely used in industries related to cosmetics, medical equipment, and beauty.
