Washbasin.Water after rinsing simultaneously gathers in washbasin 1 can impregnate hose further so as to washing hose outer wall.When triple valve 2
In the state that output end is connected with the second input terminal, infusion pump 4 and perfusion spray head 8 can recycle perfusion by the medical fluid in washbasin 1
Hose inner wall is rinsed, and the immersion effect improved to hose is circulated by medical fluid, improves the utilization rate and hose of medical fluid
Cleaning effect.
In present embodiment, the first pressure regulator valve 3 is set between triple valve 2 and washbasin 1, by the first pressure regulator valve 3 and is filled
Stream pump 4 cooperates the control, it can be achieved that for each 8 perfusion flow velocity of perfusion spray head, to accurately control in perfusing course in hose
Portion is hydraulic, that is, avoids hose from rising brokenly and guarantee the impact force of inner flexible tube inner wall again, improve cleaning effect.
Specifically, being additionally provided with enzyme in washbasin 1 washes filling pipe end 17, contained with will pass through enzyme and wash filling pipe end 17 and conveyed into washbasin 1
The reagent of active enzyme impregnates outside hose, then the output end of triple valve 2 is connected with the second input terminal, infusion pump 4 and perfusion
Active enzyme solution in washbasin 1 can be mentioned circulation perfusion wash hose inner wall by spray head 8, to reduce hose cleaning difficulty, be improved soft
Pipe cleaning efficiency.
Specifically, can be intake first by the first water inlet pipe 9 when passing through the device washing hose, with clear water washing hose,
After the completion of clear water cleaning, and opens draining/medical fluid switching valve 6 and sewage is discharged to draining position;The row of turning off after the completion of clear water rinses
Water/medical fluid switching valve 6, and reagent of the input of filling pipe end 17 containing organized enzyme is washed by enzyme and impregnates hose, after immersion again
Sewage is discharged;Draining/medical fluid switching valve is navigated into medical fluid position again, the medical fluid in explosive box is transported in washbasin 1;Medical fluid is filled out
After full washbasin 1, draining/medical fluid switching valve 6 is closed, makes medical fluid circulate flushing by infusion pump 4 and circulating line 5 soft
Pipe;Medical fluid is finally transmitted back to by explosive box by draining/medical fluid switching valve again.After medical fluid is discharged, again through the first water inlet pipe 9
Hose inner cavity is rinsed in water inlet, outer wall is rinsed by 8 rotary nozzle of the second water inlet pipe, to avoid liquor residue.
In this way, in present embodiment, by clear water flushing, active enzymatic activities processing, medical fluid disinfection and sterilization etc. to hose
It is cleaned multiple times, ensure that hose cleaning effect.
