Description
Technical field
The application belongs to medical instruments field, is specifically related to a kind of universal dispensation apparatus of infusion.
Background technique
Before infusion, medical staff is frequently necessary to mix after dissolving drug to carrying out drop extension to patient again in infusion bag,
Applied dispensing method is more, such as is directly made up a prescription using syringe, or uses special sterile dispensing device, and sterile matches
The type of medicine device is also varied.
The appearance of connector sleeve type sterile dispensing device is being made up a prescription so that the process of making up a prescription of medical staff has obtained great simplification
In the process, it need to only turn upside down, squeeze infusion bag, it is simple and convenient.Sterile dispensing device one end of the type is equipped with one
It is connected to the connector sleeve of cillin bottle, one piece of needle tubing is provided in connector sleeve for piercing through the rubber plug of cillin bottle, the other end and is equipped with one
A connector sleeve for being fixed to infusion bag rubber plug, and it is provided with the rubber plug that another piece of needle tubing passes through infusion bag, cillin bottle and infusion
Bag passes through two needle tubing connections.When in use, infusion bag is higher than and cillin bottle and is repeatedly extruded so that the liquid in infusion bag into
Enter cillin bottle and sufficiently dissolve or mix the drug in cillin bottle, then cillin bottle is higher than infusion bag and repeats above-mentioned movement, until
Medical fluid in cillin bottle is all drawn back to infusion bag.
The open end of infusion bag is typically provided with rubber plug, however, the structure of rubber plug is different between the infusion bag of different size,
Such as some infusion bags preset 1 piece of jack in rubber plug central area, some have preset 2-3 pieces in rubber plug (non-central region), and
Some then Non-precondition jacks.Since the matching requirement of the construction of connector sleeve and infusion bag rubber plug is very high, many dispensers are provided only with
For needle tubing without connector sleeve, above structure inevitably brings other problems when improving matching compatibility, such as is matching
It might have liquid medicine spill during medicine and pollute environment or medical fluid itself, influence the safety of medical staff and sufferer.
A kind of connector sleeve type sterile dispensing device, the sterile dispensing device are disclosed in Chinese patent literature CN205198574U
Structure with doubly-linked female connector, connector sleeve is interior to be equipped with buckle protrusion, can firmly be connected the infusion of cillin bottle with corresponding bore
Bag.One connector sleeve of the dispenser is the cylinder that bore matches infusion bag rubber plug, when being applied to the defeated of default 2-3 pieces of jack
When liquid bag, the central area at the axle center of infusion bag rubber plug and corresponding connector sleeve set bottom generates offset, causes connector sleeve that can not be embedded in
With fixed infusion bag rubber plug, therefore versatility receives certain restrictions.
