Medical mixed injection port

Abstract

A mixing / charging port for medical treatment capable of cleanly wiping out a residual liquid, residual blood, or the like. The mixing / charging port for medical treatment includes a disk-like valve 1 having an insertion hole at the center, a seating 7 for supporting a lower part of the periphery of the valve 1 with the center of a rear surface side of the valve 1 left unsupported, and a cover 2 for restraining the valve 1 by covering at least an upper part of the periphery of the valve 1 with the center of a front surface side of the valve 1 left uncovered, wherein a fitting hole 6 defined by an inner edge portion of the cover 2 works as an anchor for anchoring an insertion member to the mixing / charging port in a way in which the insertion member is fitted to the fitting hole when the insertion member is inserted into the insertion hole; and the thickness of the center of the valve 1 is larger than the thickness of the periphery of the valve 1, and the thickness of the edge portion of the cover provided with the fitting hole 6 substantially corresponds to the difference between the thickness of the center of the valve 1 and the thickness of the periphery of the valve 1.

Description

technical field [0001] The present invention relates to a mixed injection port for medical use, which is installed on a medical device in order to perform mixed injection of liquid from the outside of the infusion flow path, or conversely, to take liquid from the inside of the infusion flow path. of. Background technique [0002] When performing infusion or blood transfusion to patients, in order to mix different types of medicinal liquids, or to sample the liquid flowing in the infusion flow path, it is often necessary to set a side mixed injection line on the main infusion flow path. At this time, the conventional method is to provide a mixed injection port (plug) for puncturing made of rubber on the infusion flow path of the infusion device, and to pierce an injection needle or the like into the mixed injection port to perform mixed injection. [0003] However, when the needle is punctured from a position other than the predetermined puncturing part of the mixed injectio...

AI Technical Summary

Problems solved by technology

That is, first, the receiving part of the suction device of the mixing port must be deepened, and after using this shape, it is difficult to remove the liquid spilled from the valve, and it is easy to cause uncleanness.

In addition, mixed injection may start when the suction device is not fully inserted into the mixed injection port with a deep suction device receiving part.

In this case, if the amount of the mixed drug solution is small, the effective amount of the drug solution cannot be administered

Second, the valve structure becomes complicated, which will become the main cause of cost increase

In this way, when wiping off the remaining liquid or blood, due to the existence of this step, it will not be wiped off at the step portion 10, and the remaining liquid and blood cannot be wiped cleanly. go
