Description

{Safety connector for intravenous injection}

The present invention relates to a connector for safe injection of an injection solution, which is interposed between an infusion container and an infusion set during intravenous injection.

In general, intravenous injection is to directly administer a drug prescribed by a doctor into the patient's vein, and the drug injected directly into the blood vessel quickly reaches the necessary tissues of the body after passing through the heart. The effects and reactions appear quickly.

Intravenous injection is mainly performed when the prescribed drug is a drug solution that is avoided but cannot be injected intramuscularly, when the amount of the drug solution is too large even though it can be injected, or when a rapid effect of the drug is expected.

Looking at such an intravenous injection process, first, the nurse makes an injection solution in which the infusion solution and the chemical solution are mixed by injecting the prescribed drug solution into the infusion container in which the infusion solution is stored.

That is, the nurse uses a syringe to extract the prescribed amount of the drug from the ampoule or vial in which the drug is stored, and then inserts the syringe needle into the rubber stopper of the infusion container and injects the extracted drug into the infusion container. Accordingly, the infusion solution to be administered is made by mixing the stored infusion solution and the chemical solution injected through the syringe in the infusion container.

Thereafter, the nurse inserts the spike of the infusion set for injecting the injection solution into the infusion container containing the injection solution, and inserts the infusion needle into the patient's blood vessel to administer the injection solution into the patient's vein.

Here, the infusion set (IV Set) is a well-known medical device capable of injecting fluid into a patient's vein in a dropwise manner according to a quantitative amount, and is a spike that is usually inserted into a rubber stopper of an infusion container to discharge fluid. And, a drop passage provided under the spike to temporarily store the discharged sap for a certain period of time, an infusion needle connected through the drop passage tube to supply the intravenous fluid stored in the drop container, and a tube installed in the tube It consists of a flow controller that controls the amount of fluid flowing into it.

However, in the conventional intravenous injection process as described above, the following problems occurred.

First, in order to make the injection solution, the nurse inserted the injection needle of the syringe directly into the infusion container to inject the chemical solution, so it is not easy to insert the injection needle into the infusion container. There is a risk.

In other words, the infusion container is divided into a bottle-type infusion bottle and a pack-type infusion bag, and both are equipped with a rubber stopper for internal sealing, so it is not easy to insert an injection needle with a rubber stopper for injecting the chemical solution. No, there is a risk of being stabbed by the main needle or being exposed to chemicals if you make a mistake in the process of inserting.

In addition, after injecting the chemical solution into the infusion container, remove the injection needle inserted from the rubber stopper of the infusion container, and then insert the spike of the infusion set into the rubber stopper. There is a risk that bacteria may penetrate into the infusion container through the rubber stopper. Accordingly, after removing the injection needle, before inserting the spikes in the infusion set, first wipe the rubber stopper of the infusion container with a sterilization pad to ensure sterility. There is a hassle that must be secured.

In addition, when it is determined that the technical features of the present invention may be unnecessarily obscure as a matter that is already obvious to a person skilled in the art, such as a known function or a known configuration related in principle in describing the embodiment, the detailed The explanation will be omitted.

The connector for safe injection of injection solution according to the present invention is coupled between the infusion container in which the infusion solution is stored and the infusion set for injection of the injection solution. Regardless of the type of injection, it is possible to safely and conveniently administer the injection solution.

1 to 5 illustrate the configuration and operation of a connector for safe injection of an injection solution according to an embodiment of the present invention.

1 to 2, the connector for safe injection of an injection solution (100, hereinafter, abbreviated as “connector”) of the present invention includes a connection body 10, a chemical injection port 20, and a chemical solution guide piece. (30) and a ventilation port (40).

First, the connection body 10 is a part that is coupled to the infusion container 200 in which the infusion solution is stored and is connected to the infusion container 200.

Here, the infusion container 200 to which the connection body 10 is coupled includes both a bottle-type infusion bottle and a pack-type infusion bag. However, for convenience of explanation, only the infusion bottle is illustrated in the drawings and described with reference to this. I will do it.

The connection body 10 has a shape extending in a straight line, and the outer diameter gradually decreases so that it can be inserted through the rubber stopper 210 of the infusion bottle or the port of the infusion bag (not shown). The needle portion 11 having a may be formed at one end.

In addition, the main passage 12 and the sub passage 13 may be independently formed in the interior of the connection body 10 along the longitudinal direction.

The main flow path 12 is a flow path for injecting a chemical liquid or draining an injection liquid, and the sub flow path 13 is a flow path for circulation of air.

Here, the drug solution refers to a drug that is injected into the infusion container 200 for mixing with the infusion solution stored in the infusion container 200, and the injection solution is a drug produced by mixing the injected drug solution with the infusion solution, that is, a drug administered to a patient. Can be understood as meaning.

The main flow path 12 has a relatively large diameter compared to the sub flow path 13 so as to secure a sufficient drainage flow rate for the drop injection.

The main passage 12 is formed to extend from one end portion of the connection body 10, that is, from the needle portion 11 to the other end, and the sub passage 13 extends only to a portion communicating with the ventilation passage 41 to be described later. Can be formed.

On the other hand, in the connection body 10, a pair of gripping pieces 14 may be formed on the outside so that the user can easily grip the connection body 10 for use, and the connection body 10 is an infusion container. A pair of support wings 15 for supporting the coupled state of the connection body 10 may be formed so as not to be arbitrarily separated from the infusion container 200 when fitted and coupled to the 200.

Next, the chemical liquid injection port 20 is a part that allows the chemical liquid to be injected into the infusion container 200 in which the connection body 10 is fitted.

This chemical injection port 20 is formed on one side of the connection body 10 and has a chemical solution injection passage 21 through which a chemical solution to be injected into the infusion container 200 flows.

The chemical solution injection passage 21 is injected with a chemical solution through an inlet, and the outlet is connected in communication with the main passage 12 to guide the injected chemical solution to the main passage 12.

Here, the chemical solution injection passage 21 may extend inclined at a predetermined angle θ1 in a direction toward the needle 11 from an inlet through which the chemical solution is injected to an outlet communicating with the main passage 12.

That is, the chemical solution injection passage 21 is not vertically communicated with the main passage 12, and as illustrated in FIG. 3, the needle portion is based on an imaginary straight line L perpendicular to the main passage 12. It communicates with the main channel 12 while having a certain angle (θ1) gradient toward (11).

In this way, when the chemical solution injection passage 21 is inclined at a certain angle (θ1) toward the needle part 11 and communicates with the main passage 12, the injected chemical solution is placed along the inclination angle θ1 of the chemical solution injection passage 21. Since it is guided in the direction toward (11), energy of the chemical solution for moving toward the needle part 11 is increased, so that injection can be efficiently performed.

Here, if the inclination angle θ1 of the chemical injection passage 21 is too large, the coupling of the syringe 300 becomes difficult due to interference with the connection body 10, so that the syringe 300 can be coupled without interference, while The injection direction of may be appropriately selected to face the needle 11, and preferably the inclination angle θ1 may be 30°.

Meanwhile, a check valve 22 may be installed in the chemical solution injection passage 21 to allow the chemical solution to pass through only one direction in which the chemical solution is injected, but not discharged in the reverse direction.

In addition, the body of the syringe 300 from which the injection needle has been removed is coupled to the chemical injection port 20 for injection of the chemical solution. For this purpose, the outer surface of the inlet side of the chemical solution injection port 20 A known fastening structure, a lure lock structure, may be provided.

Next, the chemical solution guide piece 30 is a part that guides the chemical solution guided along the chemical solution injection channel 21 to enter the main channel 12 toward the needle part 11.

The chemical liquid guide piece 30 is formed on the chemical liquid injection passage 21, and may be formed at an outlet position of the chemical liquid injection passage 21 communicated with the main passage 12.

The chemical liquid guide piece 30 is formed to protrude from the inner circumferential surface of the chemical liquid injection passage 21, and may include an inclined guide front surface 31 and a straight rear surface 32.

The inclined induction front surface 31 protrudes from the inner circumferential surface of the chemical injection passage 21 toward the needle 11 at a certain angle θ2 inclined.

That is, as illustrated in FIG. 3, the inclined induction front surface 31 is inclined at a certain angle (θ2) toward the needle 11 when based on an imaginary straight line L perpendicular to the main passage 12 It is formed to protrude from the inner circumferential surface of the chemical solution injection passage 21 while having.

The straight rear surface 32 protrudes in a straight line from the rear of the inclined induction front surface 31 in parallel with the inner circumferential surface of the main flow path 12.

This chemical solution guide piece 30 further increases the energy of the chemical solution moving toward the needle part 11 by further changing the path of the chemical solution injected with the inclined guide front surface 31 in the direction of the needle part 11 so that injection is more efficient. Can be achieved.

Here, the inclined induction front surface 31 may have a relatively larger inclination angle θ2 than the inclination angle θ1 of the chemical solution injection passage 21, and preferably, the inclination angle of the inclined induction front surface 31 ( θ2) may be 60°.

In order for the chemical solution to be smoothly injected into the infusion solution container 200, when the injected chemical solution is guided along the chemical solution injection passage 21 and enters the main passage 12, the resistance to movement is minimized and the infusion solution container 200 enters the infusion solution container 200. It must have maximum energy of movement toward the direction of the inserted needle 11.

Thus, the present invention is guided to the first angle (θ1), that is, a 30° angle in the direction of the needle part 11 along the chemical solution injection passage 21 extending obliquely, and then to the inclined induction front surface 31 protruding obliquely. By this, the second angle θ1, that is, a 60° angle is formed so that the entry into the main flow path 12 is made.

Therefore, the chemical liquid discharged and injected from the syringe 300 increases the angle of the progress direction by 30° in the first, second, and sequential increments, thereby minimizing the resistance according to the change of the progress path, and the needle part ( 11) Efficient injection is possible by entering the direction at an angle of 60° and having the maximum moving energy.

Next, the ventilation port 40 is a part for passing air to the infusion container 200 to which the connection body 10 is coupled.

The ventilation port 40 is formed on a side surface of the connection body 10, and may be formed on a side opposite to the side on which the chemical injection port 20 is formed.

In addition, the ventilation port 40 has a ventilation passage 41 through which air can move, and the ventilation passage 41 is connected to and communicated with the sub-channel 13 of the connection body 10.

A filter member 42 may be installed in the ventilation passage 41 to filter contaminants in the air, and an air cap 43 may be provided to selectively open or close the ventilation passage 41. I can.

The ventilation port 40 is for air circulation in the infusion container 200, and when it is used in an infusion bottle requiring air circulation when the injection solution is drained, the ventilation port 40 is opened by opening the air cap 43. However, when it is used for an infusion bag that does not require air circulation during drainage, the air cap 43 may be closed to close the air circulation.

Meanwhile, the present invention having the above-described configuration may further include an injection set docking unit 50 as illustrated in FIG. 1, wherein the injection set docking unit 50 is an injection set ( It is a part that allows the connection 400) to be coupled to the connector 100 of the present invention.

This injection set docking part 50 is coupled to the other end of the connection body 10, a docking tube 51 coupled in communication with the main flow path 12, and formed on the inner lower side of the docking tube 51 A docking layer 52 may be included.

The docking tube 51 is a tube having a hollow inside so that the injection liquid discharged from the infusion container 200 can pass through the main flow path 12, and is transparent so that the inside can be seen and the spike of the infusion set 400 ( 410) may be made of a material having a certain ductility to facilitate fitting.

The docking film 52 is a thin film formed on the lower inner side of the docking tube 51, and seals the docking tube 51 from the outside, and the spike 410 of the injection set 400 is inserted into the docking tube 51. When it is lost, it is penetrated by the spike 410 so that the docking tube 51 can communicate with the spike 410.

The configuration of the present invention has been described above. Hereinafter, the operation of the present invention having the above configuration will be described with reference to FIGS. 4 and 5.

The connector 100 of the present invention makes it possible to safely and conveniently inject a chemical solution into the infusion container 200. First, as illustrated in FIG. 4, a connection body ( 10) by inserting the needle (11) of the present invention, the connector 100 of the present invention is coupled to the infusion solution container 200, and the syringe 300 containing the drug solution is injected to make an injection solution by mixing the prescribed drug solution with the infusion solution. It is coupled to the port 20.

At this time, the body of the syringe 300 from which the injection needle has been removed is coupled to the chemical injection port 20 by a lure lock, and thus, it is stabbed by the injection needle during the process of injecting the chemical solution to make an injection solution. The risk of wearing is eliminated, and convenience is also improved as there is no hassle and inconvenience of having to carefully insert the injection needle with care.

Subsequently, by pressing the syringe 300 coupled to the chemical solution injection port 20, the chemical solution is injected into the chemical solution injection passage 21. Then, the injected drug is primarily guided in the direction of the needle part 11 along the chemical solution injection passage 21 inclined at a certain angle (30°), and the route is further changed by an additional 30° by the drug solution guide piece 30. After entering the main flow path 12 while having a 60° angle toward the needle part 11, the injection is made smoothly into the infusion container 200 along the main flow path 12.

In this way, when the chemical solution is injected into the infusion solution container 200, the stored infusion solution and the injected chemical solution are mixed inside the infusion solution container 200, thereby creating an injection solution to be administered.

Therefore, when the connector 100 of the present invention is used, it is possible to safely and conveniently make an injection solution without the risk of being stabbed by an injection needle or risk of drug infection.

On the other hand, when the injection solution is made through the injection of the chemical solution as described above, as illustrated in FIG. 5, the connector 100 of the present invention is connected to the infusion container 200 as it is, and the infusion set 400 for administering the patient. ) To the connector 100.

That is, the spike 410 of the injection set 400 is inserted into the docking tube 51 of the injection set docking unit 50, and then the docking film 52 is penetrated by the spike 410, so that the connector of the present invention ( The injection set 400 is coupled to 100) so as to communicate with each other.

When the infusion set 400 is combined in this way, the infusion container 200 is inverted and fixed at a certain height, and the injection solution in the infusion container 200 is prescribed in a dropwise manner according to the usual usage method of the infusion set 400. It is enough to allow the patient to be administered as much as the amount of the prescribed dose into the patient's vein.

Therefore, when the connector 100 of the present invention is used, in the process of making an injection solution and administering the injection solution to a patient, the injection needle and the spike 410 of the infusion set 400 are alternately inserted into the infusion container 200 as in the prior art. Since the connection body 10 only needs to be inserted and coupled to the infusion container 200 once without the need to give it, the possibility that the infusion container 200 is contaminated by bacteria is minimized. Improves.

Here, when the injection solution is administered, the infusion bag in the infusion container 200 does not require air circulation because the infusion bag itself is reduced and the internal pressure is maintained even when the injection solution is drained. Since the pressure inside the infusion bottle is reduced, air circulation is required for continuous drainage.

By the way, since the connector 100 of the present invention is configured with a sub-channel 13 and a ventilation port 40 connected thereto separately from the main channel 12 for injecting a chemical solution and draining the injection solution, the injection solution of the infusion bottle is administered. If so, it can be used to allow smooth drainage of the injection solution by opening the ventilation port 40 to allow the infusion bottle to flow through the air, and when administering the injection solution in the infusion bag, the ventilation port 40 can be closed and used. It is possible to use both without being limited by the type of the container 200.

As discussed above, the connector according to the present invention has excellent safety and convenience because it can safely and conveniently inject a chemical solution and administer the injection solution to a patient without the risk of being stabbed by an injection needle or bacterial contamination. , It can be seen that the usability is also excellent because it can be used without being limited to the type of infusion container such as infusion bottle and infusion bag.

Preferred embodiments of the present invention have been described in detail above, but the technical scope of the present invention is not limited to the contents described in the above-described embodiments and drawings, and modified or It will be said that the changed equivalent configuration does not depart from the scope of the technical idea of the present invention.
