The multi-cock comprises: a first feeding hole for feeding a first medicinal liquid; a second feeding hole for feeding a second medicinal liquid; a cock housing including an outlet for discharging the first medicinal liquid and the second medicinal liquid; a cock handle installed to be rotated on the cock housing, selectively connecting the first feeding hole, the second feeding hole, and the outlet according to rotation, and having a flow path formed therein to enable a medicinal fluid to pass; and a primary filter installed in the first feeding hole and the second feeding hole, and filtering foreign materials included in a fed medicinal liquid. Accordingly, the primary filter can absorb pressure, and thus the primary filter can be prevented from being damaged by external pressure. Pores become compact by pressure, so small foreign materials included in the medicinal liquid can be filtered. While pressing the primary filter, a pressing projection of a sealed cap seals the first feeding hole or the second feeding hole, so the organization of the primary filter can be compactly maintained.

Description

A multi cock for liquid chemical injection < RTI ID = 0.0 >

TECHNICAL FIELD The present invention relates to a multi-coke for injecting a drug solution capable of immobilizing a foreign substance contained in a chemical liquid.

In general, the sap solution (drug solution) is parenterally injected into an intravenous solution such as a mixture of water and an electrolyte, a carbohydrate, an amino acid solution, a glucose solution, a plasma net, a texturizer, Or an artificial solution thereof. This solution should be mixed with other injections or collected as needed. Therefore, a 3-way multi-coke solution should be connected to the sap tube.

In this case, the injected solution mixed with the liquid is mostly stored in a glass ampoule to prevent chemical change as much as possible, and the glass ampoule is broken when the injection liquid is injected into the liquid. The minute glass fragments generated when the liquid is broken are mixed with the injection liquid, .

In order to solve the above problems, there has been disclosed a multi-way connector device using a stopcock type intravenous beverage having a built-in filter that reduces the injection resistance of Korean Utility Model Registration No. 20-0475695 (registered on Dec. 17, 2014) There is a bar.

Conventionally, a stopcock type multi-way connector device using a cocktail in which a filter with reduced injection resistance is incorporated has a liquid inflow tube integrally connected to a tube extending from a liquid storage container and a liquid inflow pipe connected to the liquid stored in the liquid storage container A liquid injection tube in which an end of a syringe in which a needle is removed is inserted so that an injection liquid or a liquid of the same kind is supplied to the injection needle, and a liquid injection tube integrally connected to a tube inserted into the blood vessel of the patient, Way connectors; And a stopcock valve formed on an upper side of a central portion of a housing constituting the external appearance of the multiway connector and opening / closing the fluid inflow tube, the injection fluid injection tube, and the fluid discharge tube by rotation, And a filter for removing fine particles formed in a cylindrical shape having a hollow portion formed inside the tube and having a predetermined length and becoming narrower toward the one end and the other end being closed while the other end is opened, The removal filter is disposed in a forward or reverse direction inside the injection liquid injection tube of the multiway connector, and the microfiltration removal filter is formed of four-leaf clover filter particles, and indicates the volume occupied by the micropores formed in the filter And to increase the porosity to reduce the injection resistance.

The conventional multi-way connector device for a cocktail-type cocktail in which a filter with reduced injection resistance is incorporated can prevent glass fragments mixed in an injection solution from being injected into a human body.

However, when the filter is solidified and the syringe is coupled to the multi-way connector device, there is a problem that the syringe is pushed and damaged at the end of the syringe, and the residue of the filter is broken into the chemical liquid.
