Description
Technical field
The invention belongs to the field of medical instrument technology, specifically, in particular to a kind of endoscope perfusion device.
Background technique
Currently, it is international some national in the disinfection and sterilizing problem to soft endoscope, using the trendy of purchase
Endoscope automatic rinser can after cleaning sterilize automatically to endoscope.According to statistics, as long as one patient 5 of endoscopy
Minute, the time of a piece scope standard of machine processing needs 25-35 minutes, for many hospitals, daily in face of a large amount of
When endoscopy case, all with cleaning machine automatic processing, scope not enough has enough to meet the need at all, needs manually to clean and carries out
Cooperation.And in view of the price problem of endoscope automatic rinser, in many small-middle hospitals certainly even without mating endoscope
Dynamic cleaning machine.Therefore, the mode of traditional artificial cleaning and sterilizing endoscope is still that can not abandon.Either handles or make by hand
With washing and disinfecting machine, thoroughly cleaning is that endoscopy disinfection is successfully crucial and basic to the first step by hand.Although current industry mark
Standard is recommended to use cleaning-sterlizing machine for endoscope, but emphasizes that the manual cleaning step before machine washing cannot be saved.
Artificial quantity can be reduced with endoscope cleaning disinfectant, reduce disinfectant exposure duration, realization cleaning and sterilizing mistake
Journey standardization, but there are not easy to clean at high cost, tiny duct disinfection, cleaning and sterilizing it is overall the time required to it is long the disadvantages of.Row
Although industry standard is recommended to use endoscope cleaning disinfectant, but emphasize that the manual cleaning step before machine washing cannot be saved.With it is automatic
In comparison, artificial cleaning and sterilizing is short not by influence of hydraulic pressure there are the time for cleaning and sterilizing；Cleaning, the advantages that disinfection cost is cheap.
Therefore, a kind of easy to operate, high reliablity and cheap artificial cleaning endoscope apparatus seems very necessary is designed.
Summary of the invention
In view of the above drawbacks of the prior art, technical problem to be solved by the invention is to provide a kind of endoscope perfusions
Device.
Technical solution of the present invention is as follows: a kind of endoscope perfusion device, it is characterised in that: set side by side on the valve body of check valve
The first half-duplex channel and the second half-duplex channel are set, the inner hole of each half-duplex channel is the step-like of big at both ends and small in middle, and unidirectional
The front end in channel is liquid outlet, and rear end is to pump mouth, and the liquid outlet of the first half-duplex channel by the first hose and attracts pipe fitting
The liquid outlet of connection, the second half-duplex channel is connect by the second hose with gas connection, and one of half-duplex channel pumps mouth
It is connected with syringe；The first steel ball of plugging action has been housed in the inside of each half-duplex channel front end, the first steel ball forward by
