It should be noted that the wire penetration piercing device 1 according to the present invention can be combined with a syringe (Syringe) or a general injection device by the joint portion 10, but the present invention mainly focuses on the case of combining with the Luer lock syringe 2. Description.

The Luer lock syringe 2 is internally formed with a space for storing a chemical solution or the like, and is similar to a normal syringe in this respect, but is formed along the outer peripheral surface of the discharge port 2a on the discharge port 2a side for discharging the chemical liquid. There is a joint port 2b, and the joint port 2b is used to achieve the joint The inner peripheral surface is formed with a thread 2c. The purpose of its formation is to achieve bonding by the joint port 2b when it is required to be firmly bonded to a special member to be connected to the discharge port 2a (refer to Fig. 3).

Further, the structure and effect of the Luer lock syringe 2 are well known in the art, and detailed descriptions thereof are omitted.

The details will be described below with reference to Figs. 1 to 4 . The wire penetration piercing device of the present invention is composed of a combination portion 10 that is coupled to a formation side of a discharge port 2a of a Luer lock syringe 1 having a space for interposing a chemical solution or the like, and a connector 20 formed on The side of the joint portion 10 is combined with the lancet 30 to adjust the angle of the lancet 30, or can be used to adjust the protruding length of the lancet 30; and the lancet 30.

The joint portion 10 is a portion that is combined with the syringe or the injection device, and can be introduced to the inside of the joint portion 10 by introducing the syringe or the liquid medicine discharge portion side of the injection device.

Such a joint portion 10 has a cylindrical shape in which one side is open, and the discharge port 2a of the Luer lock syringe 2 is inserted into the open inner side.

Further, the joint portion 10 is also coupled to the Luer lock syringe 2 in which the thread is formed in the chemical discharge portion, and the outer peripheral surface may be formed at the distal end of the joint portion 10 toward the outer direction. A protruding joint protrusion 11.

Thereby, the joint portion 10 has a cylindrical shape so as to be insertable into the joint opening 2b formed on one side of the Luer lock syringe 2, and the outer peripheral surface of the joint portion 1 preferably has an inner peripheral surface with the joint opening 2b. Corresponding width.

With this coupling protrusion 11, when the wire penetration piercing device 1 and the Luer lock syringe 2 are connected, the coupling protrusion 11 can be inserted and joined to the valley side of the thread 2c of the joint opening 2b.

That is, as shown in FIG. 3a, the discharge port 2a of the Luer lock syringe 2 is inserted inside the joint portion 10, and the outer side of the joint portion 10 is inserted into the inside of the joint port 2b by Rotating the interposed joint opening 10 allows the coupling projection 11 to rotate along the valley of the thread 2c, thereby increasing the extent to which the joint portion 10 is inserted into the joint opening 2b.

Further, the joint portion 10 has a cylindrical shape, but preferably has a tapered shape in which the diameter is gradually narrowed toward the bent bellows 23 formed on the other side. According to this, when the joint portion 10 is inserted into the joint port 2b, it will be tightly fixed, so that the airtightness can be improved and maintained, and the discharge port 2a is combined in such a manner as to be formed toward the transfer passage 231 formed inside the bent bellows 23. Thereby, the drug solution can be easily moved to the lancet 30.

In particular, external air is prevented from infiltrating into the inside of the embedding splint 1 and the Luer lock syringe 2, so that it is possible to prevent the air from being injected into the body or the chemical liquid from coming into contact with the air to cause a chemical reaction.

As described above, one side of the joint portion 10 is opened, so that the discharge port 2a of the Luer lock syringe 2 is inserted inward, and on the other side, the connector 20 is formed.

For the connector 20, as described above, in the connector 20 formed to be connected to the other side of the joint portion 10, a lancet joint portion 21 for coupling the lancet 30 is formed on one side thereof, and the lancet 30 is used for The embedding thread, the medical solution, and the like are penetrated into the skin, and the expansion portion 22 formed to be larger than the diameter of the lancet joint portion 21 is disposed at the next position of the lancet joint portion 21, and the bent bellows 23 is formed, and the bellows is bent 23 is located at the next point of the expansion portion 22 so as to be able to adjust the penetration angle of the lancet 30 or adjust the protruding length of the lancet 30.

Here, in the bent bellows 23, the one end portion is joined to the inner peripheral surface of the joint port 10, so that the chemical liquid or the like introduced into the inner side of the joint port 10 can be moved toward the lancet 30 side.

First, the lancet joint portion 21 is formed at one side of the connector 20 and formed in a direction opposite to the direction in which the joint port 10 is provided to enable the lancet 30 to be inserted.

The lancet joint portion 21 is formed to protrude from one side of the connector 20, and has a cylindrical shape, and the lancet 30 is inserted inside, so that it can be coupled with the lancet 30.

This lancet joint portion 21 is composed of a fixed guide opening 211, a lancet introduction hole 212, and a lancet fixing table 213.

The fixed guide port 211 is configured to surround the outer peripheral surface of the lancet coupling portion 21, and when the user inserts the lancet 30 into the inner side of the lancet coupling portion 21 or replaces the lancet 30, the movement of the bent bellows 23 to be described later may be performed. It is difficult for the lancet 30 to be easily inserted into the needle insertion hole 212 side.

Therefore, the user directly grasps the fixed guide port 211 with a finger to fix the connector 20, thereby allowing the lancet 30 to be smoothly inserted into the lancet introduction hole 212 side.

Further, the fixed guide opening 211 may be made of a material different from the connector 20 including the lancet joint portion 21, but it is preferably manufactured in an integrated form.

The lancet introduction hole 212 is a portion into which the lancet 30 is inserted, and the lancet introduction hole 212 is inserted through the inside of the lancet coupling portion 21, and the penetrating groove communicates with the inner space of the expansion portion 22, the transfer passage 231, and the inner side of the joint portion 10, thereby The drug solution discharged from the Luer lock syringe 10 is moved to the lancet 30 along the inside of the bending bellows 23 and the expansion portion 22.

Thereby, the introduction inclined surface 212a is formed around the lancet introduction hole 212, and the introduction inclined surface 212a is formed to be recessed from the outer side of the lance insertion hole 212 toward the inner side direction of the lancet joint portion 21, and the width of the depression is gradually changed in the above direction. A narrow taper shape. For such an introduction inclined surface 212a, in order to insert the lancet 30 by gravity, the lancet 30 is easily inserted into the small and narrow lancet introduction hole 212, while at the same time, the inserted lancet 30 is firmly fixed. It is fixed to the lancet joint portion 21, and an adhesive such as a bond is introduced to the inner side of the introduction inclined surface 212a.

As described above, the adhesive is introduced to the inner side along the introduction inclined surface 212a, so that the cured adhesive can be prevented from protruding to the outside of the lancet joint portion 21.

Further, a lancet fixing table 213 is formed inside the lancet introduction hole 212.

The lancet fixing table 213 has a shape that is recessed toward the outer peripheral surface in the interior penetrating along the lance insertion hole 212. With such a lancet fixing table 213, it is also possible to perform a locking table so that the lancet 30 introduced into the inner side of the lancet joint portion 21 can be firmly fixed.

Further, in the drawings, the lancet fixing table 213 is configured in plural, but is not limited thereto.

As described above, in the lancet joint portion 21 to which the lancet 30 is coupled, the expansion portion 22 is formed on the opposite surface of the surface into which the lancet 30 is introduced.

For the expansion portion 22, the two ends are respectively communicated with the transfer passages 231 formed on the inner side of the lancet introduction hole 212 and the inner side of the bent bellows 23, respectively, and the inner side is compared with the lancet joint portion 21 and the bent bellows 23 The inner diameter is more expanded. In the expanded portion 22, the chemical liquid transferred by the transfer channel 231 to be described later is filled therein, and the filled chemical solution is directed toward the lancet joint portion 21 and the lancet 30.

At this time, an expansion inclined surface 22a is formed at the distal end of the expansion portion 22 connected to the transfer passage 231, and the inner diameter of the expansion inclined surface 22a expands toward the side of the lancet joint portion 21.

As described above, by expanding the inclined surface 22a, the inner diameter is enlarged toward the side of the lancet joint portion 21, and the internal space is also enlarged. According to this, if the drug solution transferred from the transfer channel 231 is largely transferred by the syringe, it may not be discharged to the outside by the narrow needle 30. Therefore, the drug solution to be moved to the lancet 30 by the expansion portion 22 is first filled, and the filled drug solution can be smoothly discharged by the lancet 30.

On one surface of the above-described expanded portion 22, the lancet joint portion 21 as described above is formed to protrude, and on the other side, the bent bellows 23 is formed.

The bent bellows 23 is a bellows in the form of a cymbal, and a transfer passage 231 having a predetermined diameter is formed inside. The transfer passage 231 has a cylindrical shape and communicates with the inner side of the joint portion 10, so that the chemical liquid moved to the inner side of the joint portion 10 by the luer lock syringe 2 can be moved along the transfer passage 231 via the inside of the expansion portion 22 to Needle 30.

Such a bent bellows 23 is used to adjust the angle between the lancet 30 and the joint opening 10, or to adjust the protruding length of the lancet 30 protruding toward the outside of the joint opening 10, and more specifically, the plurality of bellows are closely attached. , thereby folding or spreading, thereby performing a function of shortening or elongating the length of the lancet 30 protruding toward the outer side of the joint opening 10, by affixing the corrugation of one side and spreading the corrugation of the other side by means of The connector 20 is bent in accordance with the difference, so that the angle formed by the lancet 30 provided on one side of the connector 20 and the joint opening 10 is adjusted.

Further, in Patent Document 3 of the prior application, since the internal space has the shape of the bent bellows 23, there is a hidden danger that the chemical liquid is sandwiched between the bent portions of the bent bellows 23, which may occur. Loss of liquid medicine.

Therefore, in the present invention, the shape of the column which is narrower than the diameter of the bent bellows 23 is specifically provided with the transfer passage 231, so that the amount of the chemical liquid which may remain in the connector 20 inside can be reduced. .

Here, the pitch between the bent bellows 23 and the transfer passage 231 is not equal, and the thickness is set depending on the position. To explain this, the first thickness t1 and the second thickness t2 will be described.

In addition, as shown in FIG. 4, the first thickness t1 as the thickness of both ends of the bent bellows 23 is more than the second thickness t2 which is the central thickness of the bent bellows 23. thick. This securely fixes the lancet joint portion 21 connected to both ends of the bent bellows 23 and the joint portion 10, and the center side is formed at a second thickness t2 which is thinner than the first thickness t1, thereby The bent bellows 23 can be easily bent at a portion formed by the second thickness t2, so that the movement is flexible and flexible, and a bent bellows 23 which can adjust the angle more smoothly and freely can be formed.

That is, it is more easily bent at the formation portion of the second thickness t2, so that the body insertion angle of the lancet 30 can be adjusted in various directions (refer to FIG. 5).

The lancet 30 is coupled to one side of the connector 20, and may be formed of a material such as a common metal material or a synthetic resin, and a plurality of lead-out holes 31 may be formed on the outer peripheral surface (refer to FIG. 7).

The purpose is to insert a part of the embedding line into the extraction hole 31 to penetrate the skin when the embedding is performed, or to supply not only the lancet 30 but also the lancet 30. The tip portion is also evenly supplied to the wide portion of the affected part.
