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 capable of preventing secondary infection from a syringe used by covering a needle with a multi stopper after use, and having the same. It is about 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.

This safety syringe has a structure in which a sleeve is assembled on the outside of a syringe. When a syringe is used, the syringe and needle are retracted into the sleeve by the elasticity of 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 so that the cylinder is locked to the reuse prevention jaw formed in the sleeve during the above action, so that the syringe once used can not 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 at 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, by inserting a separate outer stopper on the outside of the inner stopper to prevent reuse of the needle and syringe, dual plug injection to make it easy to replace the needle An object of the present invention is to provide a needle and a safety syringe having the same.

Characterized in that.

The inner stopper is a hinge portion formed on one side end of the inner stopper to be fitted into the hole formed in the needle body; An opening formed in a length direction on one side of the inner stopper so that the needle passes; And a fixing hole formed at the center of one end of the inner stopper and fitted to the needle body when the inner stopper is opened.

The fixing portion is provided with an open shape on one side so that the needle body is detachable and is preferably an elastic material.

The cross section of the fixing part may be in the shape of a circle, an ellipse, a polygon, and the like, of which one side is open, and may contact the outer surface of the needle body.

Here, the opening of the inner plug is preferably covered with vinyl to protrude to the outside through the vinyl when the needle moves.

The outer stopper may cover the inner stopper by inserting the inner stopper after the inner stopper is fixed to the needle body.

According to the double stop needle and the safety syringe with the same according to the present invention, it is possible to prevent secondary infection from the used needle and syringe by making it difficult to reuse by covering the needle with multiple stoppers after the use of the needle and the safety syringe. Disposal of the needle and multiple stoppers at once is effective in preventing accidents.

These and other objects, features and other advantages of the present invention will become more apparent by describing in detail preferred embodiments of the present invention with reference to the accompanying drawings. Hereinafter, with reference to the accompanying drawings will be described in detail a double-plug needle and a safety syringe with the same according to an embodiment of the present invention.

With reference to Figures 1 to 4 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 for transmitting the force to move the cylinder 120, the hollow cylinder 120 is formed at one end to be inserted, the drug in the inner space of the cylinder 120, and packing the inner surface of the cylinder 120 on one side It is composed of a rod 135 provided.

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 Hollow-shaped inner stopper 140 and the inner stopper 140 that is rotated during rotation is inserted into the outer stopper 150 to cover the outside.

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 stopper 120 is inserted into the needle body 108 when the inner stopper 140 is opened 143 (see FIG. 2). Here, the shape of the fixing hole 143 may vary depending on the shape of the needle body 108. For example, if the fixing hole 143 is a rectangular groove shape, the needle body 108 has a rectangular cross section so as to fit into the fixing hole 143, and in particular, the coupling needle body 108 is made of irregularities in the needle body 108 to be fixed. You can make this possible.

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 of one side is open, the needle body portion 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 needle 105 of the safety syringe unused from being 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 may cover the inner stopper 140 by inserting the inner stopper 140 after fixing the needle body 108. 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 4 to explain the state of use of the double-plug needle and the safety syringe provided with the same according to the present invention.

A user (medical person or other related person) removes the outer stopper 150 of the safety syringe and then applies a force to the front end of the inner stopper 140 or both sides of the inner stopper 140 so that the injection needle 105 has the inner stopper ( Pass through the opening 142 provided on one side of the 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.

At this time, it is preferable that the needle body 108 is rotated so that the comb surface of the needle 105 faces upward. This is when the direction of the inclined plane, the inner stopper 140 is convenient to rotate sideways around the hinge portion 148, the inner stopper 140 is usually held by 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 142 may be covered with sterile vinyl. Since the end of the injection needle 105 is sharply formed, it may be easily drilled out and protrudes to the outside.

After using the safety syringe, the user supports one side of the inner stopper 140 and moves the needle 105 to rotate into the fixing part 145 inside the inner stopper 140. The user may dispose of the inner stopper 140 and the needle 110 by separating the cylinder 120 at a time. In addition, the inner stopper 140 is inserted into the needle 105 to insert the outer stopper 150 having a predetermined space formed inside the cover 105 to cover the injection needle 105 in duplicate. 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, after opening the outer stopper 150 by placing a mark (mark) on the upper end of the inner stopper 140 of the injection needle unit 110, the mark (marking) of the inner stopper 140 can be used to turn 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 the identification easier by using a marker (mark).

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