Description

Vial assembly for transporting medical fluid to syringe

The present invention relates to a vial assembly for transporting a medical liquid to a syringe, and more particularly, to a syringe that can be easily taken out through a syringe without the use of a needle from a vial containing a medical liquid such as a chemical liquid, particularly a viscous chemical liquid. It relates to a vial assembly for transporting a medical liquid.

In general, a vial (hereinafter referred to as a vial assembly) refers to a vial or a storage container in which internal storage materials such as contact lenses, as well as other chemical solutions such as injection solutions and powdered injections, are kept sterile. This vial assembly is sealed by a vial cap to prevent leakage and deterioration of the contents being stored, and to block the inflow of foreign substances from the outside, and is formed in various shapes to be safely stored and transported.

The conventional vial assembly may include a vial container and a vial cap sealing the opening of the vial container. The vial container forms a space to store a medical liquid such as a chemical solution, and may be formed of a sterile, antibacterial-treated glass material, or a plastic material that has passed a predetermined pharmaceutical container test method. The vial cap may be provided to seal the opening of the vial container.

The medical liquid contained in the vial container also moves the syringe through the needle.

However, when the medical liquid contained in the vial container has viscosity, when the medical liquid contained in the vial container is moved to a syringe, time and power may be consumed during the transfer if a needle having a narrow diameter is used. In addition, in the process of transferring to the needle, bubbles are generated in the medical liquid in the vial container, which takes time to remove the bubbles.

Therefore, there is a need for a vial assembly that transports medical liquids from a vial container to a syringe with a syringe that can facilitate the movement of medical liquids, especially viscous chemicals, and prevents bubbles from occurring when the liquid moves. .

7 is a view schematically showing a state in which the vial assembly 100 according to an embodiment of the present invention is used in connection with the syringe 200.

Referring to FIG. 7, the vial assembly 100 of the present invention may exist in a state in which the vial 110 is positioned below and the adapter 121 is positioned above the vial 110 before use. In this state, when transferring the chemical solution to the syringe 200 for use of the chemical solution inside the vial 110, the vial 110 is positioned above and the adapter 121 is positioned downward. The vial assembly 100 is turned over. In this case, an air layer in which the chemical solution does not exist may be positioned between the adapter 121 and the upper side of the vial 110.

When the adapter 121 is positioned downward, the flow path pipe member 123, specifically the end 1232a of the flow path pipe 1232 is located in the air layer between the vial 110 and the chemical solution. .

When the syringe 200 is coupled to the connecting member 122, the transfer pipe 211 is inserted into the hollow 122s of the connecting protrusion, and the luer lock 210 is the connecting member 122 It may be screwed to the screw thread 1211 formed on the outer surface of the to be in close contact.

When pressure is applied to the syringe 200 to transfer the chemical solution contained in the vial 110, the chemical solution is transferred from the vial 110 to the syringe 200 through the transfer pipe 211. At this time, the chemical solution is transferred to the syringe 200 by the suction pressure of the syringe 200, and external air is introduced through the flow pipe member 123 through the vent pipe 1231. In addition, as the medical liquid is transferred to the syringe 200 through the connector 120 according to the pressing force of the syringe 200, air bubbles may flow into the liquid side. It does not disappear quickly, and may be located on the upper side of the chemical solution. In addition, the air introduced into the vent pipe 1231 is discharged to the end portion 1232a of the flow path pipe 1232 and flows into the air layer. Accordingly, the pressure inside the vial 110 and the outside of the vial 110 can be equally maintained.

In addition, when the syringe 200 sucks the chemical, air is introduced in comparison to the suction pressure, and as the end of the flow path pipe 1232 is positioned in the air layer, as in the present invention, it is introduced into the vial 110. Since air is not generated in the chemical solution, the generation of bubbles with the chemical solution can be minimized.When the chemical solution is transferred to the syringe 200 and air is introduced into the chemical solution to generate bubbles, when the chemical solution has a higher viscosity than water The higher it is, the more time it takes for the air bubbles to escape from the chemical solution or for the generated air bubbles to disappear. However, as the end of the flow path pipe 1232 is arranged in the air layer as in the present invention, the generation of bubbles with the chemical solution is minimized, and thus it is possible to prevent bubbles from flowing into the syringe 200 together with the chemical solution. The inflow of can be facilitated. In addition, since the pressure of the air layer and the external pressure are kept constant, even a chemical liquid having a high viscosity can be easily transferred to the syringe 200. In addition, air bubbles introduced into the chemical solution may rise to the top of the chemical solution. At this time, as the chemical solution is transported to the syringe 200 according to the pressurization of the syringe 200, air bubbles may also be introduced into the syringe 200. However, as the air bubbles are located only in the front of the syringe 200, when the syringe 200 is pressed in reverse, the air can be easily discharged to the outside of the syringe.

Those of ordinary skill in the art to which the present invention pertains will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, it should be understood that the embodiments described above are illustrative in all respects and are not limiting. The scope of the present invention is indicated by the scope of the claims to be described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts are included in the scope of the present invention.
