Description
Technical field
The invention belongs to medical mechanical domains, and in particular to a kind of pre-filled two-chamber injector.
Background technique
In medical procedure, needs can be usually encountered by injector, drug is sent to treatment cavity (rectum, nasal cavity, ear canal
Deng) carry out local administration the case where, will generally by injector such as cavity/canal drug administration treatment bacterium, mould or mycoplasma infection
Drug is sent to therapentic part；Simultaneously as the difference of medicines structure and property, drug combination can be the first choice of clinical protocol, if
Some drugs are mixed to the reduction that can cause medicine stability and drug effect for a long time, as acid group and alkali root drug can occur to neutralize instead
It answers, so would generally be by different classes of drug pre-stored in different vessels, to meet the stability requirement of storage drug.It is existing
There was only single-chamber injector in clinic, in application, generally requiring more injectors being repeatedly inserted into progress using injector personnel, increases
Add labor intensity, also brings sense of discomfort to treated personnel, use is very inconvenient.And two-chamber injector can well solve
This problem.
Summary of the invention
The object of the present invention is to provide for storing the two-chamber injector of different pharmaceutical component, solves present clinic and only have
Single-chamber injector needs for more injectors to be repeatedly inserted into when application to inject, solve nursing staff's large labor intensity and
The sense of discomfort problem of treated personnel;Also solve mixed water injection drug and product-filled stability problem simultaneously.
In order to solve the above technical problems, the technical solution adopted by the present invention is that,
A kind of pre-filled two-chamber injector, including cylinder, handle, push rod, seal cap, it is characterised in that cylinder is by outer barrel, interior
Cylinder composition, cylinder body bottom have aperture, and there are dismountable seal cap, cylinder upper end opening in cylinder bottom end, and push rod is the double-deck push rod,
By internal layer push rod, outer layer push rod composition, outer layer push rod matches with outer barrel barrel dliameter size, internal layer push rod and inner cylinder barrel dliameter ruler
It is very little to match.
The pre-filled two-chamber injector, it is characterised in that have sealing ring in outer barrel, in outer diameter and outer barrel
Diameter size matches, and internal diameter matches with inner cylinder outer diameter, there is sealing column in inner cylinder, sealing column outer diameter with
Inner cylinder internal diameter matches.
The pre-filled two-chamber injector, which is characterized in that outer barrel inner seal ring is annular shape.
The pre-filled two-chamber injector, which is characterized in that cylinder body bottom aperture is divided into aperture one and aperture two, inner cylinder
Aperture one is arranged at body bottom, and aperture two is arranged at outer barrel bottom.
The pre-filled two-chamber injector, which is characterized in that inner cylinder is connected with outer barrel by bottom, primary to be molded
Molding.
The pre-filled two-chamber injector, which is characterized in that inner cylinder bottom is lower than outer barrel bottom.
The pre-filled two-chamber injector, which is characterized in that have a cylindrical protrusions, protrusion and inner cylinder among seal cap
Body bottom, which is portalled, to match.
The pre-filled two-chamber injector, which is characterized in that inner cylinder bottom opening one among interior cylinder body bottom, and
There is one, outer barrel bottom opening two there are one or more.
The application method of the pre-filled two-chamber injector, cylinder body bottom put on seal cap, drug one are filled into interior
Cylinder, then drug two is injected into outer barrel, sealing ring is pushed into outer barrel, sealing column is pushed into inner cylinder, completes two kinds
The preliminary filling of drug seals, and the double-deck push rod is inserted into cylinder when use, seal cap is opened, pushes push rod, two medical fluids portal from bottom
Into injecting position.
The beneficial effects of the present invention are:
Pre-filled two-chamber injector, can be by different classes of drug pre-stored in different vessels, to meet storage drug
Stability requirement, while more injectors need not be repeatedly inserted into needs when the application of single-chamber injector and push away by two-chamber injector
Note, alleviates nursing staff's labor intensity and the sense of discomfort problem of treated personnel.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
