Show, will disposably collect wooden pail for urine taking-up, and finish changing after new collection wooden pail for urine, rotate the spiral arm from the good probe of new grafting and it is new once
Property urinary catheter.By the new property urinary catheter of catheter grafting, change bladder irrigation bag and human bladder is connected by conduit, open
Dynamic electric control valve, can also supply flushing liquor naturally without using electric control valve.During with electric control valve, input speed can be preset
Degree and infusion amount.By spring scale and decoction density conversion its input quantity, and automatic closing electric control valve door.
When controlled micturition, urine can be imported into by catheter and urinary catheter in the collection wooden pail for urine, and is calculated and counted
Measure urination amount.The fluid level adjusting apparatus can make collection wooden pail for urine be in horizontality all the time.The data calculated by probe
To be more accurate.
The largest benefit for the mode that this kind is calculated is that can reduce error by the algorithm of data metering, i.e., suffer from every time
When person urinates, the concussion change of data can be all produced, reason is that fluid level adjusting apparatus can cause to collect waving for wooden pail for urine, separately
Outer urine is flowed into collection wooden pail for urine, and originally the liquid level of urine can also float, and equally cause the vibrations of measurement data, when data pass through one
When the section time is no longer shaken, the variable quantity of a liquid level increment just occurs, the maximum calculated before is changed plus this
Amount can just draw specific total amount, and this total amount can evade by evaporator strip Lai data error.This is also the equipment
Maximum feature and benefit.The real-time monitoring to urine discharge is realized, is measured.
