As shown in fig. 1 to 6, the multi-needle module A1 for skin application of the present invention is connected to an injector S and mounted to an injection device, and generally includes a needle 400, a cap 100, a housing 200, and a connector 300 in configuration.
In which one or more needles 400 are formed.
The cap 100 has a front panel 150 and a container 140, the front panel 150 has a needle hole 110 through which the needle 400 passes and an injection hole 120 into which an adhesive is injected, and the container 140 has an opening 130 at the rear and has an empty interior. A needle guide tube (not shown) may be formed inside the cap 100 to extend from the needle hole 110 through which the needle 400 passes, and the needle 400 may be stably assembled through the needle guide tube.
The housing 200 has an opening coupled to the rear opening of the cap 100, a space formed therein, and a syringe coupling portion 220 connected to the syringe S.
The housing 200 is formed with an introduction hole 230 formed through the center of the bottom and communicating with the syringe coupling part 220 and a plurality of dispersion channels 240 communicating with the introduction hole 230, and a liquid containing part 242 into which one end of the needle 400 is inserted is formed at an end of each dispersion channel.
The housing 200 is formed with an introduction hole 230 formed through the center of the bottom and communicating with the syringe coupling part 220 and a plurality of dispersion channels 240 communicating with the introduction hole 230, and a liquid containing part 242 into which one end of the needle 400 is inserted is formed at an end of each dispersion channel.
The dispersion channel 240 may be arranged in various forms according to the number of needles, and variously formed in a shape such that the medicine injected with the needles can be smoothly dispersed to be injected. The needles 400 may be arranged in various forms according to the number thereof, and are not limited to a specific shape.
The connector 300 is inserted into the housing 200, has an adhesive injection portion 320 formed on a side surface thereof so as to be filled with an adhesive B, and has a plurality of needles 400 mounted on an upper portion thereof.
The adhesive injection portion 320 is formed to be inserted into the housing 200 so as to form a space and to be filled with an adhesive. The appearance of the adhesive injection part 320 is not limited to a specific shape, but is included in order to form a space to fill the adhesive and to be concaved inward.
Preferably, it may be formed to be inclined from the upper portion toward the lower portion, the upper portion into which the adhesive B flows is a wide space, and thus the adhesive easily flows in, and the adhesive B may flow down along the inclined surface toward the lower portion, so that the adhesive B may be relatively easily filled in the upper space and the spaced space of the coupling member 300 inside the cap.
Referring to fig. 4, the connector 300 is inserted into the receiving portion 140 of the cap 100 and spaced apart from the lower portion of the front panel 150 by a predetermined distance, so that the adhesive B is filled in the spaced space. The adhesive B can be easily filled in the space spaced apart and the upper space of the connection member 300 inside the cap.
The connector 300 is closely attached to the inner bottom of the housing 200, and an insertion portion 360 is formed to be inserted and coupled closely to the inner sidewall of the housing 200 in a side protrusion manner.
According to one embodiment, the opening of the cap 100 and the opening of the housing 200 are brought into close contact with each other, and the cap 100 and the housing 200 can be bonded together by the adhesive B injected into the inside, and the needle 400, the cap 100, the housing 200, and the connector 300 can be bonded and fixed together by the adhesive B.
According to another embodiment, the outer surface of the opening of the cap 100 is recessed to form an insertion boss 180, and the insertion boss 180 is closely attached to the inner surface of the opening 201 of the housing 200.
Preferably, referring to fig. 4, the opening 130 of the cap 100 is formed to reach a position p1 of 1/10 to 9/10 of the length of the inner surface of the opening 201 of the case 200. Therefore, the adhesive B can be filled in a recessed portion that is recessed by the same amount as the thickness t1 of the opening portion of the cap 100 so as to be able to bond the inner surface of the opening portion 201 of the case 200, and the cap 100, the case 200, and the connector 300 can be bonded together. In addition, an inner surface of the opening portion of the cap 100 may be cut outward to form an insertion boss, and in this case, an outer surface of the opening portion 201 of the case 200 is recessed to form an insertion boss in a manner corresponding to the insertion boss of the cap 100, so that the insertion boss of the cap 100 and the insertion boss of the case 100 are closely adhered to each other and firmly coupled. Therefore, even in the case where a strong pressure is applied during the process of filling the adhesive B in the spaced-apart spaces, the adhesive B can be prevented from leaking to the outside of the multi-needle module for skin application through the connection portion of the cap 100 and the housing 200.
The housing 200 is formed with a syringe coupling portion 220 communicating with an introduction hole 230 formed through the center of the bottom portion.
Referring to fig. 6, the syringe coupling part 220 is formed at one end with a syringe coupling hole 222 and is formed inside with a passage 223.
The syringe coupling portion 220 is formed in a circular or elliptical shape, but an engaging surface 227 having a flat linear surface is formed at least one portion of the outer circumferential surface to prevent idling. Preferably, flat engagement surfaces 227 having a linear surface shape are formed on both side surfaces of the syringe coupling portion 220. When a syringe having a shape corresponding to the circular or oval shape of the syringe coupling portion 220 is coupled, the syringe coupling portion 220 may be idly rotated after being coupled to the syringe, but the syringe may be stably coupled and used without being idly rotated even after being coupled to both side surfaces of the syringe coupling portion 220 due to the flat locking surface 227 having the linear surface shape.
On the other hand, the syringe coupling portion 220 has locking projections 225, 225a, 225b, 225c formed on the outer peripheral surface.
The locking protrusions 225, 225a, 225b, 225c may be variously formed in a quadrangle, a circle, an ellipse, etc., and are formed to protrude from the syringe coupling part 220, and the thus protruding locking protrusions 225 are coupled to the injection device G.
As shown in fig. 5a, the locking protrusion 225a may be formed with a linear portion 225-2 having a flat linear surface at least one portion of the outer circumferential surface to prevent rotation. Preferably, a flat linear portion 225-2 having a linear surface shape is formed on both side surfaces of the locking protrusion 225 a. When the syringe having a shape corresponding to the circular or elliptical shape of the locking protrusion 225a is coupled to the syringe, the locking protrusion 225a idles after being coupled to the syringe, but the syringe is not idled even after being coupled to both side surfaces of the locking protrusion 225a due to the flat linear surface-shaped linear portion 225-2, and thus can be stably coupled to and used.
As shown in fig. 5b, the locking surface 227 and the locking protrusion 225b may be formed by adding a thick layer to the remaining portion except a portion of the outer circumferential surface of the syringe coupling portion 220, and the syringe coupling portion 220 is formed in a circular or elliptical shape, but the locking surface 227 having a flat linear surface is formed at least at one portion of the outer circumferential surface to prevent idling. The locking protrusion 225b has a circular or elliptical shape, and a linear portion 225-2 having a flat linear surface is formed at least one portion of the outer circumferential surface to prevent rotation.
As shown in fig. 5c, the locking surface 227 and the locking protrusion 225c may be formed by adding a layer thick along the outer circumferential surface of the syringe coupling portion 220, and the locking surface 227 having a flat linear surface may be formed at least at one portion of the outer circumferential surface to prevent the idling. The locking protrusion 225c has a circular or elliptical shape, and a linear portion 225-2 having a flat linear surface is formed at least one portion of the outer circumferential surface to prevent rotation. Therefore, the multi-needle module of the present invention is fixed without being separated and is not idled by inserting the coupling syringe coupling portion 220 and the locking protrusions 225, 225a, 225b, 225c into the mounting groove (not shown) formed in the injection device G, so that the multi-needle module can be stably coupled.
On the other hand, fig. 7 is a diagram showing a multi-needle module for skin application of an embodiment provided with 9 needles.
Fig. 8 is a view showing a screw needle type in which 9 needles are provided and the housing 200 is coupled in a screw coupling manner.
In the conventional needle assembly process, the bonding is performed in two steps, and after a needle holder (corresponding to the "connector 300" of the present application) is inserted, the needle is once bonded, a needle guide (corresponding to the "housing 200" of the present application) is inserted, and a syringe guide (corresponding to the "cap 100" of the present application) is inserted, and then, a secondary bonding liquid is injected into the adhesive injection hole on the rear side, and then, the bonding liquid is removed from the jig, and the needle module is assembled, so that the manufacturing process is complicated.
In addition, conventionally, since an adhesive injection hole is formed at the rear end of the needle and the adhesive is injected through the adhesive injection hole, in order to inject the adhesive into the adhesive injection hole at the rear end of the needle, it is required to deform the shape of the locking protrusion so as to prevent the locking protrusion 225 formed at the rear end of the needle from interfering with it. In addition, conventionally, a needle module is inserted into a jig in an assembled state, a cap portion into which a needle is inserted is positioned in the jig, a connector for fixing the needle is inserted, and then the rear of the needle module is positioned in an upward direction, and an adhesive is injected through an adhesive injection hole provided in the rear of the needle module, and after fixing, the jig is removed to manufacture the needle. However, by improving this, the present invention removes an adhesive input hole at the rear end of the needle and injects an adhesive through the injection hole 120 in front and fills the inside, so that the manufacturing process can be greatly simplified, and the shape of the catching protrusion 225 is not limited, so that the catching protrusion 225 can be formed in various sizes and appearances.
Although described with respect to preferred embodiments, those skilled in the art will readily recognize various modifications and changes that may be made without departing from the spirit and scope of the present invention, and it is intended that such changes and modifications be covered by the appended claims.
