Description

Filter syringe with valve {A filter syringe with valve}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable syringe used in the medical field, wherein the glass fragments generated when a filter part is installed at the end of a syringe cylinder to cut an injection drug ampule are mixed with a drug and eventually inserted into a human body. It relates to a filter syringe having a valve for preventing.

In general, the method of injecting the human body of the drug includes oral administration, injection method such as injecting the drug directly into the body using a syringe. Injection method is widely used because of the advantage that the absorption of the drug faster and faster than the oral administration.

Injections are also used when oral administration is not possible due to inability to pitch.

Injections cannot be given orally because of unconsciousness or nausea or vomiting.

②In case of urgent need to administer large amount of medicine such as blood transfusion or fluid, including chemotherapy for severe infectious disease

③In case of expecting the absorption of medicines in critical condition

④In case of using drug without formulation other than injection such as streptomycin

⑤ When oral administration is difficult to irritate or absorb digestive mucosa.

However, despite its limited use, injections are widely used because of their merits and the limitations of oral administration.

However, glass fragments and rubber fragments from ampules and vials used as injection liquid containers are mixed with drugs, sucked by syringes, and injected into the body during injection, usually staying in the area, but sometimes blood flow Therefore, the lungs sequentially lead to kidneys through various organs such as liver and spleen. When these glass fragments block the blood vessels, there is a risk of chronic tissue necrosis, angiosarcoma, and embolism by blocking the blood supply.In addition, ampoules of anticancer drugs injected into the spine can enter the spinal fluid. You can even go to the brain.

In order to solve this problem, there have been many studies such as a syringe needle (filter syringe) in which a filter is fixed to a syringe needle.

Korean Patent Publication No. 1009815860000 discloses a hub 110 connected to the neck part 15 of the syringe 1, an injection liquid suction part 115 integrally formed on the front side of the hub 110, and A syringe tip fixed to the inside of the hub 110 and fixed to the front neck portion 15 of the syringe 1, the hub 110 has a locking jaw 122 therein; ) To protrude, close contact with the front of the filter 120, and fit the bushing 130 to the rear of the filter 120 to fix the filter 120 to the hub 110, the locking jaw 122 is A space portion 140 is formed in the hub 110 by forming a predetermined gap between the suction portion 115, and the space portion 140 spreads the glass particles K to the entire front surface of the filter 120. It is characterized in that it is configured to filter out the glass particles (K) through the filter 120 when the suction of the injection liquid 60 to be filtered over. Syringes and safety filter tip is which technology,

Korean Laid-Open Patent Publication No. 1020050108169 has a cylinder having a space therein and an injection liquid discharge portion formed at a predetermined position, a push rod moving along the longitudinal direction of the cylinder in the space within the cylinder, and coupled to a predetermined position of the push rod. In the disposable syringe provided with a piston for providing a compressive force or a suction force while being moved together in an airtight contact with the cylinder during the movement of the push rod, and a fixed member fixed to the needle is coupled to the cylinder, The filter is provided on the outside to protect the needle in a state of encapsulation, and to prevent the entry of foreign substances and antibacterial treatment, the filter having a filtering part fixed by the first and second filtering part separation prevention jaw and the second filtering part leaving prevention jaw. Disclosed is a filter structure and a manufacturing method of a disposable syringe comprising,

Korean Patent Publication No. 1020060002713 provides a lid with a filter on the outside of a syringe needle to prevent the insoluble material from being inserted into the syringe, thereby preventing the insoluble material from being inserted into the human body when the drug is injected. A syringe is described,

Publication No. 1020060128967 discloses a male luer end; Female luer ends; A channel for fluid transfer between the female and male luer ends; Valve means movable between a closed position and an open position; Bias means for biasing the valve means towards the closed position; It can be seen that a valve assembly is disclosed which includes a drive means extending to the male luer end and connected to the valve means for driving the valve means when the female luer end of the medical brace is connected with the male luer end.

In the conventional techniques as described above, when cutting the injection ampoule, fine glass powder is precipitated in the injection ampoule, and the precipitated fine glass powder is added together with the injection portion in the space of the cylinder to be administered to the patient as it is. The problem of causing serious medical accidents by remaining in the blood in the patient's body or digging into the flesh and causing rotting was solved.However, after injecting the injection liquid in the ampoule with a syringe using a filter syringe in a disposable syringe, the filter needle was removed. There is a problem in that the replacement of the normal needle, and the user is stuck or contaminated with the needle,

In Korean Laid-Open Patent Publication No. 1020050108169 and No. 1020060002713, a problem to be solved by the present invention is that a cumbersome problem of inserting a component having a separate filter on the outer side of a syringe needle and inserting it into an ampoule is provided.

The present invention fills the injection solution filled in the injection ampoule without exposing the needle of the disposable syringe to the outside in order to solve the above problems, and when the injection (injection) using the filter handle attached to the syringe is injected through the filter It is a problem solving means of the present invention to provide a filter syringe with a valve configured to be injected.

The present invention installs a valve with a built-in filter in the injection portion of the disposable syringe to inject the injection liquid, and then operate the valve to be injected (injected) through the filter, without a separate device, that is, using only a conventional syringe needle By injecting the injection solution in the ampoule into the syringe and injecting the patient in the same manner as in the prior art, the user can be prevented from being stuck by the needle when filling the injection and also more safely protects against safety accidents when used in patients with acquired immunodeficiency syndrome. In addition, by preventing the injection of foreign substances, such as fine glass chips that are precipitated when cutting the injection ampoule, there is an effect that can prevent in advance medical accidents that dig into blood or flesh in the human body to rot.
