BACKGROUND ART Syringes are medical instruments used for injecting medicines or the like into a human body or for extracting human tissues and are widely used in the medical field.

Such a syringe typically includes a needle retainer member, a syringe, and a piston to hold the needle. The needle-fixing member is a member for connecting the needle to the syringe and needs to be strongly coupled to the syringe so that syringe and separation do not occur when the medicine is injected or the tissue is sucked.

However, it is common that the needle is composed of a very thin tube so that it can easily penetrate the human body, so that occasionally, when the large pressure is applied, the needle fixing member is detached from the syringe.

In particular, in the case of extracting and injecting a material having a relatively large mass such as fat tissue or having a relatively high solidity, the syringe immobilization member can not withstand the internal pressure of the syringe, resulting in disconnection of the syringe fixing member from the syringe, leading to medical accidents, Water may be unnecessarily exhausted.

Therefore, it is necessary to develop means for strongly fixing the needle-fixing member to the syringe.

Patent No. 10-1239947

SUMMARY OF THE INVENTION The present invention has been conceived to solve the above-mentioned problems, and an object of the present invention is to provide an injection needle fixing device, An adapter for a syringe which fixes the needle fixing member; And a connection holder disposed in front of the syringe for connecting the needle-fixing member and the syringe adapter to the syringe for the syringe; / RTI >

The syringe adapter including a connection portion inserted into the hollow portion and a head connected to the connection portion and disposed in front of the syringe,

Wherein the syringe adapter and the syringe holder fixing member are connected to each other through a threaded portion, the syringe adapter is screwed to the connection holder after the needle-fixing member is screwed to the connection holder, The needle-holding member is pressed,

Wherein the connection holder includes a first female threaded portion formed on an inner circumferential surface of the hollow, the adapter for a syringe includes a first male threaded portion formed on an outer circumferential surface of the connecting portion, and the first female threaded portion and the first male threaded portion have different screw pitches Wherein the first male screw portion has a smaller screw pitch than the first female screw so that the advancing speed of the syringe adapter when the syringe adapter and the needle fixing member are rotated is smaller than the advancing speed of the needle fixing member, And a locking phenomenon between the connection holder and the adapter for the syringe.

In order to achieve the above object, a set of adapters for a syringe according to the present invention comprises: a needle fixing member to which a needle is connected; An adapter for a syringe which fixes the needle fixing member; And a connection holder disposed in front of the syringe for connecting the needle-fixing member and the syringe adapter to the syringe for the syringe; / RTI >

The syringe adapter including a connection portion inserted into the hollow portion and a head connected to the connection portion and disposed in front of the syringe,

Wherein the syringe adapter and the syringe holder fixing member are connected to each other through a threaded portion, the syringe adapter is screwed to the connection holder after the needle-fixing member is screwed to the connection holder, The needle-holding member is pressed,

Wherein the connection holder includes a first female threaded portion formed on an inner circumferential surface of the hollow, the adapter for a syringe includes a first male threaded portion formed on an outer circumferential surface of the connecting portion, and the first female threaded portion and the first male threaded portion have different screw pitches Wherein the first male screw portion has a smaller screw pitch than the first female screw so that the advancing speed of the syringe adapter when the syringe adapter and the needle fixing member are rotated is smaller than the advancing speed of the needle fixing member, And a locking phenomenon is established between the connection holder and the adapter for the syringe.

Preferably, the first female screw portion and the first male screw portion are configured to be opposed to each other.

Preferably, the adapter for the syringe and the connection holder comprise a material having a different hardness.

Preferably, the syringe adapter or the connection holder comprises a metal material.

Preferably, irregularities are formed on the outer circumferential surface of the head.

Preferably, the adapter for a syringe includes a cylindrical reinforcing rib extending from the head to cover at least a portion of an outer circumferential surface of the connecting holder,

The inner peripheral surface of the reinforcing rib is provided with a fitting concavo-convex portion.

The set of adapters for a syringe according to the present invention is configured such that the pitches of the first male threaded portion and the first female threaded portion formed on the connection holder and the adapter for the syringe are different from each other so that the connection can be made more rigid.

That is, since the pitches of the first male threaded portion and the first female threaded portion are different from each other, the rotation of the needle adapter and the advancement speed of the needle fixing member are different from each other, The locking phenomenon occurs because the speed at which they are released from each other is different. That is, when the screw is simply screwed, since there is no such locking phenomenon, there is only a frictional force due to a dynamic frictional force when the screw parts are mutually released. However, since the screw parts having different pitches are fastened to each other like the present invention, A greater force is required to release the threaded connection of the needle-fixing member.

Further, when the syringe adapter and the connection holder are screwed together and fixed, as the pitches are different from each other, the interference fit is made in addition to the general screw connection. Therefore, by such interference fit effect, The screw connection between the male screw portions can be made more firm.

The first male threaded portion and the first female threaded portion interfere with each other to maintain a stopped state. Therefore, in order to release the threaded engagement between the first male threaded portion and the first female threaded portion, It is necessary to apply a force exceeding the static frictional force between the first female screw portion and the first female screw portion.

In addition, since the locking phenomenon is caused by the tightening between the threads due to the interference fit, it is necessary to damage the thread between the first and second female thread portions to release the thread engagement between the first and second female thread portions, So that the connection between the adapter for the syringe and the connection holder can be made more firmly.

In addition, since the first needle thread portion formed on the syringe adapter and the first internal thread portion formed on the connection holder are connected through the first female threaded portion formed on the connection holder, the two-point connection is achieved, Since the connection between the first male threaded portion and the first female threaded portion is achieved through interference fit, more rigid fixation of the needle holding member can be achieved.

In addition, the syringe adapter includes a cylindrical rib extending from the head to cover at least a portion of the outer circumferential surface of the connecting holder, and the inner circumferential surface of the cylindrical rib is formed with a fitting concavo-convex portion, Can be formed.

FIG. 8 is a view showing a syringe according to an embodiment of the present invention, and FIGS. 9 and 10 are views showing a coupling structure of a syringe according to an embodiment of the present invention.

A syringe 10 including a set of syringe adapters 1 according to the present invention is comprised of a needle holding member 20, a syringe 30 and a piston 40, 30 for supporting and fixing the needle-fixing member 20 is disposed.

A set (1) for a syringe according to the present invention is a set (1) for a syringe for preventing the release of a needle, comprising: a syringe adapter (100) for fixing a needle fixing member (20); And a connection holder 200 disposed in front of the syringe 30 and connecting the syringe adapter 100 to the syringe 30,

The syringe adapter 100 includes a connection part 120 inserted into the hollow and a head connected to the connection part 120 and disposed in front of the syringe 110)

Wherein the syringe adapter 100 and the connection holder 200 are connected to each other through a threaded portion and the connection holder 200 includes a first female threaded portion 210, The first female threaded portion 210 and the first male threaded portion 130 have different thread pitches and are configured to be interference fit with each other.

The term adapter set 1 for a syringe, as generally described herein, refers to a member of a syringe, or a member, or member of a part of a set of syringe modules, It can be understood that it is a comprehensive representation of a predetermined member for supporting.

The connection holder 200 is disposed in front of the syringe 30 of the syringe 10. 1, the connection holder 200 may be formed integrally with the syringe 30 to constitute a part of the syringe 30, or may be a separate member as shown in FIG. 2, But is not limited to, the syringe 30 of the set 10 in a detachable manner or the syringe 30 of the syringe set 10 in a semi-permanent manner. For example, when the connection holder 200 is integrally formed with the syringe 30 and is formed as a part of the syringe 30, the syringe 30 may have a configuration in which the front of the syringe 30 protrudes in a cylindrical shape.

The connection holder 200 may have a hollow cylindrical configuration. Accordingly, the needle fixing member 20 can be coupled to the syringe 30 through the hollow formed in the connection holder 200.

Meanwhile, a first female threaded portion 210 may be formed on the hollow inner surface of the connection holder 200. 3 and 4, the needle-fixing member 20 may be screwed and coupled to the syringe 30 through the first female threaded portion 210. As shown in FIGS. A predetermined male threaded portion may be formed on the rear side of the needle holding member 20 to achieve screw connection between the needle holding member 20 and the connection holder 200, But not limited thereto.

Then, through the first female screw portion 210, a screw connection between the adapter 200 for a syringe described later and the connection holder 200 can be achieved. That is, after the needle-fixing member 20 is screwed to the connection holder 200, the adapter 100 for a syringe is screwed to the connection holder 200 so that the adapter 100 for a syringe is screw- (20). Meanwhile, the screw connection between the adapter 100 for a syringe and the connection holder 200 may not be a general screw connection but may be an interference fit by a connection between screws having different pitches, which will be described later.

The syringe adapter 100 is connected to the connection holder 200, and can be fixed by supporting the needle-fixing member 20.

5, the syringe adapter 100 is formed in a cylindrical shape having a hollow as a whole and has a head 110 and a connecting portion 120 provided at a rear end of the head 110. [ As shown in FIGS. 6 and 7, the needle holder fixing member 20 may partially penetrate through the hollow, and the rear end of the connection portion 120 may prevent the needle holder fixing member 20 from coming off And a locking jaw. In addition, it is also possible that the needle-fixing member 20 is fitted and fixed to the rear end of the connection portion 120. According to the above configuration, when the needle-fixing member 20, the adapter 100 for a syringe, and the connection holder 200 are coupled to each other, at least a portion of the needle-fixing member 20 is inserted into the adapter 100 for a syringe, And the connection holder 200, as shown in FIG.

A first female thread portion 210 is formed on the inside of the hollow of the connection holder 200 and a first male thread portion 130 is formed on the outer side of the connection portion 120 of the adapter 100 for a syringe, The connection holder 200 and the adapter 100 for a syringe can be coupled to each other through the threaded connection of the first female threaded portion 130 and the first female threaded portion 210. [

At this time, the pitches of the screws constituting the first male threaded portion 130 and the first female threaded portion 210 may be different from each other. Here, the pitch can be understood to mean a distance between threads, and it can be understood as a distance that the connection holder 200 or the adapter 100 for a syringe advances or retracts when making one revolution through a thread .

For example, when the pitch of the first male threaded portion 130 is P1 and the pitch of the first female threaded portion 210 is P2, the values P1 and P2 may be different from each other. On the other hand, the pitches are different from each other in the case where the first male threaded portion 130 and the first female threaded portion 210 have pitches different from each other at all, . For example, when the pitches of the first male threaded portions 130 are partially different from each other and the pitch of the first female threaded portions 210 is uniform, the first male threaded portion 130 and the first female threaded portion 210 ) May be partially different from each other. Preferably, the pitch of the first male threaded portions 130 may be smaller than the pitch of the first female threaded portions 210.

As described above, since the pitches of the first male screw part 130 and the first female screw part 210 are different from each other, the connection between the connection holder 200 and the adapter 100 for a syringe can be further strengthened.

The pitches of the first male threaded portion 130 and the first female threaded portion 210 are different from each other and the rotation of the syringe adapter 100 and the needle holding member 20 And thus the advancing speed may be different from each other. 9 and 10, the advancing distance R2 when the syringe adapter 100 makes one rotation (Q1) through the first male screw portion 130 is smaller than the forward distance R2 between the needle fixing member 20 (Q2) through the first female screw portion 210 when the first female screw portion 210 rotates in the first direction. As a result, the needle-holding member 20 is free to be screwed and does not slip, and when the rotation is continued, the pressure increases at the contact portion between the rear portion of the adapter 100 for a syringe and the needle fixing member 20, The member 20 is inserted between the threads of the adapter 100 for the syringe and the threads of the connection holder 200 so as to be fixed and locked.

That is, due to the above-described structure, the locking phenomenon occurs because the fastening speed is released when the fastening is released and released. That is, when the screw is simply screwed, since there is no such locking phenomenon, there is only a frictional force due to a dynamic frictional force when the screw parts are mutually released. However, since the screw parts having different pitches are fastened to each other like the present invention, A greater force is required to release the connection between the connection holder 200 and the adapter 100 for a syringe.

Further, when the connection holder 200 and the syringe adapter 100 are screwed together and fixed, as the pitches are different from each other, the interference fit is made in addition to the general screw connection. Therefore, The threaded connection between the first female thread portion 210 and the first male thread portion 130 can be further strengthened.

The first male screw portion 130 and the first female screw portion 210 are interfered with each other and remain in a stopped state and thus the first female screw portion 130 and the first female screw portion 210 , It is necessary to apply a force exceeding the static frictional force between the first male screw portion 130 and the first female screw portion 210. Therefore, I can endure it.

In order to release the threaded engagement between the first male threaded portion 130 and the first female threaded portion 210, it is necessary to damage the threads between the first female threaded portion 130 and the first female threaded portion 210 And the threaded connection is maintained to a range of the external force necessary for such damage, so that the connection between the connection holder 200 and the adapter 100 for a syringe can be made more firmly.

The difference between the pitch of the first male threaded portion 130 and the pitch of the first female threaded portion 210 is not limited and the first female threaded portion 210 and the first male threaded portion 130 may be partially It is also possible to have different pitches.

On the other hand, if the pitch difference is excessively large or small, the configuration may become difficult or the above-mentioned interference fit effect may not be achieved. In this case, the pitch difference may be very fine, The pitch of the female threaded portion 210 and the pitch of the first male threaded portion 130 are sufficient even if they have a ratio of about 1: 0.9.

In addition, preferably, the connection holder 200 and the adapter 100 for a syringe may be made of a material having a different hardness from each other.

That is, when the interference fit is performed as described above, partial damage is generated between threads and screw connection and clamping are achieved, so that at least one of the connection holder 200 and the adapter 100 for a syringe is relatively rigid The connection holder 200 and the adapter 100 for a syringe may be made of a material having a different hardness from each other. Preferably, any one of the connection holder 200 and the adapter 100 for a syringe may include, but is not limited to, a metal material having a relatively high hardness. At this time, preferably, the adapter 100 for a syringe, which is easily formed as a separate member, may be made of a metal material, but is not limited thereto.

Preferably, the syringe adapter 100 is formed in a cylindrical shape having a hollow inside, and the hollow inner side surface of the syringe adapter 100 is formed with a latching protrusion for supporting the needle fixing member 20.

As described above, since the syringe adapter 100 is fixed to the connection holder 200 by interference fit while the needle-fixing member 20 is inserted into the connection holder 200, And the rear end of the needle 100 may be configured as a hook to prevent the needle holding member 20 from being detached.

The connection holder 200 and the adapter for a syringe 100 are connected to each other through the first male thread 130 formed on the connection part 120 and the first female thread 210 formed on the connection holder 200, The needle 20 can be more firmly connected to the syringe 30 and the needle fixing member 20 can be detached from the syringe 30 during the injection and extraction of the drug Can be effectively prevented.

That is, the needle holding member 20 is screwed through the first female threaded portion 210 formed on the connection holder 200, and the first male threaded portion 130 formed on the syringe adapter 100 and the connection Since the first female threaded portion 210 formed on the holder 200 is connected to the second female threaded portion 210 and the connection between the first male threaded portion 130 and the first female threaded portion 210 is made through interference fit A more rigid fixation of the needle-fixing member 20 can be achieved.

Referring to FIG. 11, the head 110 of the adapter 100 for a syringe according to an embodiment may be provided with concave and convex portions 115.

The shape of the concave and convexes 115 is not limited to the one shown in FIG. 11. For example, as shown in FIG. 11, a plurality of rectilinear grooves intersecting with oblique lines are formed And the like. Since the irregularities 115 are formed in the head 110 of the syringe adapter 100, the frictional force between the syringe adapter 100 and the user's hand is increased to facilitate gripping and manipulation, The connection and disconnection between the connection holder 200 and the connection holder 200 can be easily achieved.

That is, the syringe adapter 100 may have a double hollow. Accordingly, the needle holder fixing member 20 is accommodated in the inner hollow and the connection holder 200 is accommodated in the outer hollow. At this time, the outer hollow is formed by a cylindrical reinforcing rib 140 surrounding the outer circumference of the connecting portion 120, and the reinforcing rib 140 may extend from the head 110.

The inner circumferential surface of the reinforcing rib 140 is formed with a concave-convex portion 150. The concave-convex portion 150 can be pressed against the outer circumference of the front portion of the connecting holder 200. [ Here, the fitting concave / convex portion 150 refers to any means that is constituted by, for example, a female thread portion or a three-dimensional portion having a predetermined protrusion to achieve interference fit with the outer circumferential surface of the connection holder 200 ≪ / RTI >

Accordingly, the adapter set 1 for a syringe according to the present invention may have a structure in which the connection between the adapter 100 for a syringe and the connection holder 200 is achieved in a double manner. That is, not only the connection between the first female thread portion 210 and the first male thread portion 130 but also the fitting concave / convex portion 150 is constricted with respect to the outer peripheral portion of the connection holder 200, A double connection can be achieved and a more solid connection can be formed.
