Description

Single plug twoport composite cover

Technical field

This utility model relates to a kind of medical package apparatus, relates in particular to a kind of single plug twoport composite cover.

Background technology

At present, composite cover in the infusion vessels such as the plastic infusion bottle using in medical and health industry and flexible-package transfusion bag is divided into single port Dan Sai and twoport pair is filled in two types, and dosing mouth seal cover wherein and loading mouth seal cover have again draw-ring type, pull dividing of folding and torsional mode.

In the infusion vessel of single port Dan Sai, because dosing mouth and loading mouth are same passage, dosing mouth and loading mouth can not separate separately, therefore easily cause cross-contamination, not too health.

In the infusion vessel of the two plugs of twoport, dosing mouth and loading mouth are all positioned at the roof upper surface of enclosing cover, the two shape is identical, the word or the symbol that only, in lid top wall, mark are distinguished, during dosing owing to only opening dosing mouth seal cover, therefore can to dosing mouth and loading mouth, distinguish at an easy rate, can not make mistakes; But, after loading mouth seal cover is opened, while especially changing infusion vessel in infusion process, being easy to dosing mouth and loading mouth to obscure, mistake is used as dosing mouth as loading mouth, is therefore easy to cause cross-contamination, and sanitary condition can not be fully guaranteed.

Utility model content

This utility model, for deficiency, provides a kind of single plug twoport composite cover of clean hygiene.

The technical scheme that this utility model solves the problems of the technologies described above is as follows:

A single plug twoport composite cover, comprises enclosing cover and inner cap, and inner cap is positioned at enclosing cover, and the sidewall of enclosing cover is connected with the sidewall of inner cap is airtight, the airtight plug that is connected with between the roof of enclosing cover and the roof of inner cap; The roof of inner cap has interior dosing mouth, and interior dosing mouth is circular, and the center of circle of interior dosing mouth and the center of circle of interior lid top wall coincide, the airtight dosing mouth diaphragm seal that is connected with in interior dosing mouth place; The roof of enclosing cover has loading mouth, loading mouth is also circular, the airtight loading mouth seal cover that is connected with in loading mouth place, above loading mouth seal cover, be fixedly connected with connecting cylinder, connecting cylinder upper end is fixedly connected with trigger piece, it is characterized in that, the center of circle of loading mouth and the center of circle of outer lid top wall coincide, and the radius of loading mouth is less than the radius of interior dosing mouth; The roof of enclosing cover also has outer dosing mouth, outer dosing mouth is 1/2nd toroidals, the width of outer dosing mouth be greater than syringe needle diameter, be less than the diameter of plastic infusion syringe needle, it is peripheral that outer dosing mouth is opened in loading mouth, the cylindrical center of circle of outer dosing mouth and the inner circle center of circle all coincide with the center of circle of loading mouth, and the exradius of outer dosing mouth is less than the radius of interior dosing mouth; The airtight dosing mouth seal cover that is connected with in outer dosing mouth place, above dosing mouth seal cover, be fixedly connected with brace, brace upper end is fixedly connected with draw ring, the cylindrical center of circle of draw ring and the inner circle center of circle all coincide with the center of circle of loading mouth, the vertical height of draw ring is higher than the vertical height of trigger piece, and the operating side of trigger piece is positioned at draw ring below.

This utility model is arranged on the draw ring below on dosing mouth seal cover by the trigger piece operating side on loading mouth seal cover, during use, must first dosing mouth seal cover be opened, and therefore can loading mouth be used as to dosing mouth by mistake; Due to the width of outer dosing mouth be greater than syringe needle diameter, be less than the diameter of plastic infusion syringe needle, while therefore infusing, can dosing mouth be used as to loading mouth by mistake yet, loading mouth and dosing mouth be independently use separately, the two can cross-contamination, so clean hygiene.
