Description
Technical field
This utility model belongs to chemical device technical field and in particular to a kind of negative-pressure type for chemiluminescence instrument is clear
Wash system.
Background technology
In chemiluminescence instrument, weigh instrument performance to have a critically important index is exactly residual contamination rate.Because city
On face, the different blood serum sample of most chemiluminescence instrument detection is all to be drawn by sample pin to add.Therefore sample needle
Cleaning just seem most important.Sample needle has the service sink of various structures when cleaning.
Most of instruments adopt on the market spring formula or waterfall type, have certain defect, such as spring formula cleaning
Can avoid hanging liquid, but cleaning performance is poor.Waterfall type cleaning performance is good, but hangs liquid phenomenon and cannot avoid.Modified form simultaneously
Service sink although above-mentioned requirements can also be met simultaneously, but in order to clean up, scavenging period is long, typically will
The time of 2s-3s.Requirement can be met for small throughput miniature instrument, such as per hour test quantity be 120 samples with
Under instrument, requirement can be met, but for high flux such as 200 flux, the throughput instruments of even more high, this clear
Wash that mode is excessively slow, longer scavenging period can seriously tie down the speed of service of whole machine, since it is desired that a kind of quick, efficiently
Cleaning way.
Utility model content
The purpose of this utility model is to provide a kind of negative-pressure type purging system for chemiluminescence instrument, on solving
State the problem proposing in background technology.
For achieving the above object, this utility model provides a kind of following technical scheme: negative pressure for chemiluminescence instrument
Formula purging system, including cleanout fluid bucket, diaphragm pump, pipeline, sample pin, service sink, gas liquid two purpose switch valve, Miniature negative pressure pump,
