Description
Technical field
The present invention relates to medical instruments fields, and in particular, to a kind of dual-purpose duplex mixing syringe connector and double
Join mixing syringe.
Background technology
Duplex mixing syringe on current market cannot be applicable in two kinds of occupation modes of application type and hysteroscope type simultaneously, therefore
Doctor cannot switch occupation mode at any time according to the use demand in surgical procedure.Common method is to configure application type simultaneously
Special duplex mixing syringe and hysteroscope type two kinds of products of special duplex mixing syringe, doctor when in use can only basis
It needs to use the certain types of duplex mixing syringe of one of which.If an operation needs while using application type and hysteroscope
Two kinds of occupation modes of type, it usually needs prepare two sets of different types of duplex mixing syringes, and be equipped with two sets of medical sprays simultaneously
It applies reagent and not only results in unnecessary waste in this way, and increase patient since medical spraying reagent price general charged is more expensive
Financial burden；Or doctor manually mixes two injection tubes from a type of duplex when needing to switch occupation mode
It closes and is removed on syringe, then be re-assembled on another type of duplex mixing syringe, such operation is during surgery
Extremely inconvenient, it can not only extend operating time, but also increase the risk of operation.
Hysteroscope type duplex mixing syringe mixes in advance in order to avoid two kinds of medicaments, and hybrid position setting is double in hysteroscope type
Join the nozzle location of mixing syringe, such factor determines the connection of duplex mixing syringe threeway tube module and long nozzle
It is necessarily designed to the good integral structure of leakproofness, is mixed in advance before avoiding two kinds of reagents from not reaching nozzle.Common solution
Scheme is to be made of one entire duplex mixing syringe threeway tube module with long nozzle, but due to being confined to plastic product
Processing technology, this scheme can not be come out with injection molding.Therefore, most of producer solves this using metal cavity pipe is increased
Problem.But metal cavity pipe can only use the very low sterilizing side of this efficiency of gaseous sterilization currently without good sterilizing scheme
Formula.
Alternatively possible scheme is by duplex mixing syringe threeway tube module and long sprinkler design at being detachably connected
's.But since hysteroscope type duplex mixing syringe nozzle position can have problem using common threaded connection, it is difficult to ensure that double
Two cavities of the threeway tube module of connection mixer, which just seal during screw thread rotation with two cavities of long nozzle, to be docked.
Once it is inaccurate that docking occurs, it may appear that two kinds of liquid of duplex mixer are also less than nozzle and have just mixed in advance, coagulate
The problem of glue blocks.
Therefore, existing duplex mixing syringe can not switch two kinds of occupation modes of application type and hysteroscope type quickly.There is an urgent need for
Designing a kind of can be suitable for application type simultaneously and hysteroscope type two kinds of occupation modes and the duplex mixing syringe that can be switched fast
Connector and duplex mixing syringe.
