Needle With Double Cover and Safety Syringe Using The Same}

The present invention relates to a double stopper needle and a safety syringe having the same, and more particularly, a double stopper needle and a second stopper that can prevent secondary infection from a syringe used by covering the needle with a multi-stopper after use. Relates to a safety syringe.

In general, a syringe can be divided into a barrel, which is a main body having an inner space, and a needle, respectively, which can be largely divided into a detachable syringe used by combining a needle with a barrel, and an integrated syringe with an integrated needle. have.

In most cases, the detachable syringe consists of a medium and large syringe with a relatively large barrel capacity, and the integrated syringe is a small syringe with a relatively small barrel capacity.

These syringes are used to select the appropriate syringe depending on the amount of drug to be administered or the condition of the patient.In the case of a detachable syringe, after using the syringe, the syringe is capped and the needle is removed from the barrel. The needles are disposed of separately, and in the case of an integrated syringe, the caps are capped on the needles to dispose of the needles and barrels integrally.

However, the syringe handler may be stuck in the needle when the cap is reinserted into the needle after using the syringe.In addition, during the disposal of the syringe, the cap on the needle may be separated and the disposal person may be stuck in the needle. There is always.

When a medical staff or a person disposing of a syringe is stuck in a needle of a used syringe, there is a high possibility that the patient's disease may be infected by the blood of the patient remaining in the needle, and such an example has been reported substantially.

For this reason, safety syringes have recently been used as a way to prevent secondary infections of patients due to stabbing of medical staff or syringe disposal handlers from needles of used syringes.

The safety syringe has a structure in which a sleeve is assembled on the outside of the syringe, and when the syringe is used, the syringe and needle are retracted into the sleeve by the elastic member so that the needle is positioned inside the sleeve. It is designed to prevent the needle from sticking.

In addition, the safety syringe allows the cylinder to be locked to the reuse prevention jaw formed in the sleeve during the above operation, so that the syringe used once cannot be reused.

However, such a conventional safety syringe is difficult to manufacture a sleeve because a part of the middle portion of the sleeve is made of a reuse prevention jaw, and in particular, since the reuse prevention jaw is formed on both sides of the inside of the sleeve, the syringe is used after the use of the syringe. Pulling or pushing the jammed syringe reduces the syringe to a position prior to use and has a problem in that it can be reused.

In addition, the conventional safety syringe has a problem that it is impossible to replace the needle because the needle is fixed to the cylinder integrally.

The present invention was conceived in view of the above point, by rotating a separate outer stopper on the outside of the inner stopper to prevent reuse of the needle and syringe, double stopper to easily replace the needle An object of the present invention is to provide an injection needle and a safety syringe having the same.

Side sectional view of the state.

With reference to Figures 1 to 6 to look at the double stopper needle and the safety syringe provided with the same according to the present invention. The safety syringe according to the present invention is an injection needle (105) and needle (110) composed of an injection needle (105) and an injection needle body (108) for fixing an injection needle (105) inserted into a skin of a patient. Piston 130 that transmits the force to move the cylinder 120, the drug in the inner space of the cylinder 120, etc. in which the tip portion 115 is formed at one end to be inserted, and packing the inner surface of the cylinder 120 on one side ) Is provided with a rod 135.

The inside of the cylinder 120 forms a large diameter space in which the drug sucked into the needle 105 and the tip 115 is filled. The diameter of the cylinder 120 is made of various sizes according to the purpose, when the diameter of the cylinder 120 is relatively large, the tip portion 115 to which the needle 105 is coupled is eccentric from the center of the cylinder 120 It may also be formed in a closed position. However, this tip 115 is generally located at the center of the cylinder 120. The cylinder 120 is inserted with a piston 130 for inhaling the drug into the cylinder 120 or injecting the inhaled drug into the patient. The outer surface of the piston 130 and the inner surface of the cylinder 120 maintain a mutual hermetic state. The piston 130 is connected by the rod 135 so as to operate forward and backward from the outside of the cylinder 120.

In particular, the dual plug needle according to the present invention is fixed to the inner side in order to fix the needle 105 is formed 145 and hinged to one side of the needle body portion 108 is separated from the needle 105 The inner stopper 140 and the outer stopper 140 which is in sliding contact with the inner stopper 140 which rotates in time and covers the outer side is included.

The inner stopper 140 has a hinge portion 148 formed at one end of the inner stopper 140 and an injection needle 105 so as to fit into a hole (not shown) formed in the needle body 108. Fixing hole that is formed in the opening portion 142 formed in the longitudinal direction on one side of the stopper 140, the inner end of the inner stopper 120, the needle 108 is inserted into the needle body 108 when the inner stopper 140 is opened 143, and a protrusion 149 regularly formed on the outer circumferential surface of the inner cap 140 (see FIG. 2). Here, the shape of the fixing hole 143 may vary depending on the shape of the needle body 108. This also applies to the fixing hole 153 of the outer cap 150. For example, if the fixing holes 143 and 153 have a rectangular groove shape, the needle body 108 may be inserted into the fixing hole 143 of the inner stopper 140 and the fixing hole 153 of the outer stopper 150. The cross section is rectangular to make, especially in the needle body portion 108 can be made irregularities to be able to secure the coupling.

Here, the fixing part 145 is provided with an open shape on one side such that the needle body 108 is detachable and is preferably made of an elastic material.

The cross section of the fixing part 145 is in the shape of a circle, an ellipse, a polygon, and the like, which is open at one side thereof, and preferably contacts the outer side surface of the needle body 108.

Fixing part 145 in the present invention is a circular shape with one side open, needle body 108 is drawn through the opening 142 of the inner stopper 140, after the fixing part 145 Through the open one side of the fixed portion 145 is introduced into the inner space. At this time, the fixing part 145 is made of an elastic material, and when the needle body 108 is pulled in, it is opened to both sides, and when the needle part 145 is completely inserted into the inner space of the fixing part 145, the fixing part 145 is gathered back to the center. 108 can be completely fixed (see FIG. 3).

The opening 142 of the inner stopper 140 is covered with vinyl so that the needle 105 penetrates the vinyl and protrudes outward when the needle 105 moves. Herein, the vinyl is preferably in a state sterilized by a disinfectant. This is to prevent the unused safety needle injection needle 105 is contaminated by external dust or bacteria. If there is no problem of external contamination, the opening 142 may not be covered with another material.

The outer stopper 150 is open at one side such that the injection needle 105 protrudes outward, and the outer circumferential surface of the inner stopper 140 and the inner circumferential surface of the outer stopper 150 are rotated in contact with each other, so that the opening of the inner stopper 140 is opened. 142 can be opened or closed. That is, by rotating the outer stopper 150 provided on the outer side of the inner stopper 140 to match the opening 142 of the inner stopper 140 and the opening of the outer stopper, the needle 105 is opened to move. When the external stopper 150 is rotated by a predetermined angle, the opening 142 of the internal stopper 140 is closed by one surface of the external stopper 150 (see FIGS. 6A to 6C).

4 to 6, the protrusion 149 provided on the outer circumferential surface of the inner stopper 140 may rotate the rail unit 155 formed on the inner circumferential surface of the outer stopper 150 when the outer stopper 150 rotates. Moving along and fitted to the depression 158 formed on the path of the rail 155, it is possible to fix the open and closed state of the inner stopper 140 and the outer stopper (150). The inner stopper 140 and the outer stopper 150 may be spaced apart by a predetermined interval so that the protrusion 149 may be easily moved.

The opening of the outer cap can be covered with vinyl sterilized with a disinfectant. This prevents the contamination of the needle 105 of the unused safety syringe and, after use, introduces the needle 105 into the inner stopper 140 and then covers it again, thereby causing secondary infection due to protrusion of the needle 105. To prevent them.

1 to 6 to explain the state of use of the double-closure needle and the safety syringe provided with the same according to the present invention.

The user (medical person or other concerned person) rotates the outer stopper 150 of the safety syringe to match the open part of the outer stopper 150 with the open part 142 of the inner stopper 140 (see FIG. 6 (a)). . At this time, the protrusion 149 of the inner stopper 140 is fitted into the recessed part 158 of the outer stopper 150 to be held in an open state. Afterwards, a force is applied to both ends of the front end of the outer stopper 150 or the outer stopper 150 so that the injection needle 105 passes through the opening 142 provided on one side of the inner stopper 140. Since the injection needle body 108 and the inner stopper 140 are hinged, the injection needle 105 rotates about the hinge 148 of the inner stopper 140. In addition, the needle body 108 is fitted into the fixing hole 143 of the inner stopper 140 and the fixing hole 153 of the outer stopper 150.

At this time, the needle body 108 is preferably rotated so that the comb surface of the needle 105 is directed upward. This is when the direction of the inclined plane, the inner stopper 140 is convenient to rotate sideways around the hinge portion 148, it is common to hold the inner stopper 140 with the thumb and index finger, injection needle ( If the inclined surface of 105) is upward, the probability of contamination decreases (see FIG. 3).

Here, the opening portion 142 and the open portion of the outer cap 150 may be covered with sterile vinyl. Since the tip of the injection needle 105 is sharply formed, it can be easily drilled and protruded to the outside.

After using the safety syringe, the user supports one side of the outer stopper 150 and then rotates the needle 105 to introduce the needle body 108 into the fixing part 145 inside the inner stopper 140. . The user may dispose of the outer stopper 150, the inner stopper 140, and the needle 110 by separating the cylinder 120 from one time. In addition, after inserting the inner stopper 140 to the needle 105 to make a sliding contact with the outer stopper 150 is formed in a predetermined space on the inner side provided separately so as to cover the injection needle 105 in duplicate (Fig. 6 (b), see FIG. 6 (c)). At this time, the protrusion 149 of the inner stopper 140 is fitted into the recessed part 158 of the outer stopper 150 to be kept closed.

Thereby, the secondary infection can be prevented from the used syringe by covering the needle 105 with multiple stoppers after the use of the safety syringe.

Here, the mark (mark) on the upper end of the outer cap 150 can be used to turn the mark (mark) of the outer cap 150 to the upper end. In this case, the oblique side of the needle 105 is also adjusted to go to the top. As described above, the use of the safety syringe can be facilitated by making identification easy by using a marker (indication).

In the above, the double stopper needle is not only a safety syringe, but also an emergency blood donation pack (the needle is thick and the blood donation pack is connected instead of the syringe body), and a blood transfusion set can be used everywhere.

According to the present invention, a double stopper needle and a safety syringe having the same can prevent secondary infection from the used syringe by making it difficult to reuse by covering the needle with a multi stopper after use and separating the needle and the multi stopper at once. By discarding it, it is effective to prevent accidents.

Although a preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described specific embodiment. That is, a person having ordinary knowledge in the technical field to which the present invention belongs can make many changes and modifications to the present invention without departing from the spirit and scope of the appended utility model claims, and all such appropriate changes and modifications.
