Abstract
There is provided a hub for a syringe having a safety filter that prevents the glass particles of the ampoule from being injected into the patient. The hub for a syringe according to an embodiment of the present invention includes a needle bundle having one needle coupled to one end, and one or more first through holes and one or more second through holes coupled to the needle bundle. It is composed of a guide valve and a flexible material and is coupled to the rear of the guide valve to open the second through hole of the guide valve when the injection liquid enters the cylinder, and close the second through hole of the guide valve when the injection liquid exits the cylinder. The valve, a filter member attached to the front of the guide valve and covering the first through hole, and assembled so as to be movable up and down in front of the filter member, are in close contact with the filter member when the injection liquid comes in and separated from the filter member when the injection liquid comes out. And a fixing body for fixing the guide valve inside the needle bundle. According to the present invention, there is no need for a separate operation such as inserting or removing a filter when sucking or releasing the injection, thereby simplifying the injection process while eliminating the possibility of injecting the glass particles of the ampoule into the patient.
Description
The present invention relates to a hub for a syringe having a safety filter, and more particularly, the injection process is simple and ampoule by passing through the filter member when injecting the injection solution to the patient without injecting the injection liquid into the syringe. It relates to a hub for a syringe having a safety filter to prevent the injection of free particles into the patient.
In general, as shown in FIG. 1, the syringe 1 includes a

However, when the
In order to solve this problem, Patent Publication No. 10-2005-0108169 proposes a syringe provided with a filter to protect the injection needle on the outside of the fixing member in addition to preventing foreign substances and antibacterial treatment. . The syringe of such a configuration filters the glass particles of the ampoule by the filter when aspirating the injection, but the injection process is cumbersome because when the injection to the patient has to remove the filter containing the ampoule glass particles.
In addition, Patent No. 981586 secures a safety filter tip equipped with a filter to the
In order to solve this problem, the present inventors proposed a safety filter for a syringe and a syringe having the same in Korean Patent Registration No. 1178986. Using a syringe with a safety filter for the syringe eliminates the need for additional action, such as inserting or removing the filter when sucking or injecting the injection, eliminating the possibility of injecting free particles from the ampoule into the patient. The process is simple. However, since the safety filter for the syringe is assembled in contact with the neck portion inside the cylinder of the syringe, the assembly is inferior, and when applied to an existing syringe, it takes up a space where the chemical liquid enters, causing an error in the chemical liquid scale. have.
SUMMARY OF THE INVENTION The present invention has been made in view of this point, and an object of the present invention is to provide a hub for a syringe having a safety filter that is easy to inject and easy to assemble in a production process while eliminating the possibility of injecting a glass particle of an ampoule into a patient. It is done.
A hub for a syringe according to an embodiment of the present invention includes a needle bundle having a needle coupled to one end, one or more first through holes and one or more second through holes, and coupled to the needle bundle. Composed of a guide valve and a flexible material, coupled to the back of the guide valve to open the second through-hole of the guide valve when the injection liquid enters the cylinder, and the second through hole of the guide valve when the injection liquid exits the cylinder A valve for closing, a filter member attached to the front of the guide valve to cover the first through hole, and assembled so as to be movable up and down in front of the filter member, in close contact with the filter member when the injection liquid comes in, and separated from the filter member when the injection liquid exits. A prevention valve and a fixing body for fixing the guide valve inside the needle bundle.
The guide valve has a disc shaped body in which a first through hole and a second through hole are formed, and the first through hole is located outward from the center of the disc than the second through hole. The filter member is attached to the body of the guide valve as a disc with an open center, and is configured such that the second through hole is positioned at the open part and the first through hole is located at the unopened part when attached to the guide valve.
A third through hole for fixing the valve is formed at the center of the body of the guide valve. The valve includes a pillar portion inserted into the third through hole, and a disc portion for opening or closing the second through hole. The guide valve includes a hollow cylindrical pillar formed between the first through hole and the second through hole on the body, and a cutout formed on an upper portion of the cylindrical pillar.
The filter member may use a paper filter, and may be attached to the guide valve by ultrasonic welding.
The inside of the needle bundle is formed with a projection or a recess for engaging the fixed body. The fixed body has a hollow shape to be coupled to the neck portion of the syringe, and the outer side of the fixed body is formed with a recess or projection having a shape corresponding to the protrusion or recess at a position corresponding to the protrusion or recess of the needle bundle. It is.
According to the present invention, there is no need for a separate operation such as inserting or removing a filter when sucking or releasing the injection, thereby simplifying the injection process while eliminating the possibility of injecting the glass particles of the ampoule into the patient. In addition, since the assembly is completed by assembling the safety filter assembly to the needle bundle and fixed with a fixed body, the production process is simple. In addition, since the hub in which the safety filter of the present invention is assembled to the existing syringe body can be used by assembling, the compatibility in use is also excellent.
