Description
Technical field
The utility model is related to a kind of part-structures of Medical Devices, are to be related to one kind for Hemodialysis liquid specifically
The automatic quantitative blanking machine of liquid make-up machine.
Background technology
Hemo system needs constantly suck the dialysis concentrate prepared in patient procedure is treated, existing to be provided to dialysis machine
The mode of dialyzate probably has following four：
First, hospital's purchase dialysis dry powder, then certain proportion reverse osmosis water is added in by shop instruction, with modeling after stirring and filtering
It transports to after charging basket packing beside every hemo system and is drawn for hemo system, the plastic barrel after is needed to clean and sterilized, and is cleaned and is disappeared
Dialyzate is dispensed after poison again.Its shortcoming is：
1st, the dialysate concentration fluctuating error prepared every time is big, and the water added in every time is all observed by people and controlled.Concentration
Error is big, influences whether hemo system therapeutic effect；
2nd, the daily amount of labour of staff is big, and the Dialysis center of 50 bed is two classes of patients daily, per the work of nature
It needs to carry 200 barrels of dialyzates as personnel, every barrel of dialyzate is at 10 kilograms or so；
3rd, the plastic barrel of dialyzate is filled in the presence of repeatedly using, if cleaning and sterilizing is not controlled, can cause plastic barrel
Cross contamination, bacterium, endotoxin detection are exceeded, directly influence dialysis quality.
2nd, using the finished product barreled dialyzate produced by dialysis dry powder producer in factory according to GMP requirements.Its shortcoming is：
1st, hospital using the cost of same dosage dialyzate than using the of high cost of dialysis dry powder, the plastics of barreled dialyzate
Bucket is entirely with medical grade plastic, and the cost of a plastic barrel, which is spread out on every person-portion dialyzate, needs 5 yuan, increase hospital's expenditure into
This；
2nd, the plastic barrel is not recycled according to clinical waste, increases the pollution to environment；
3rd, transport and carrying cost ratio dry powder are high.Particularly the original ward of hospital is just nervous, also to take out a big storehouse
Storehouse stores dialyzate.
3rd, using central liquid supply system, dialyzate is provided to every hemo system.Its shortcoming：
1st, central fluid supply uses longer pipeline, using sealing and circulating feed flow.It needs to empty pipeline after dialysis every time
In dialyzate and needed before dialysis starts with the clear water in the dialyzate discharge line of normal concentration, the two processes
All there are the wastes of dialyzate；
2nd, central fluid supply pipeline is connected with hemo system pipette, it is necessary to destroy hemo system original structure, cuts pipette, in
Between plus quick switching joint.Sealing ring is easy to aging in use for quick coupling, causes leakage, influences the entire ring of blood dialysis room
Border；
3rd, personalized dialysis is can not achieve, each dialysis patient state of an illness is different, therefore the formula of dialyzate is also different.
Central fluid supply can only provide a kind of all usable formula of all patients, can not meet the personalized dialysis of individuals patients.
4th, unit liquid make-up machine by bed, shortcoming：
A person-portion dialysis powder is added in every time, is used after all having dissolved for hemo system.It is remaining in machine after dialysis
Liquid needs all to exhaust, and could put into the dry powder of a person-portion again, is used for second patient.The machine cannot continuously put into dry
Powder and continuous preparation fresh dialysis fluid.
Existing liquid make-up machine can not realize the now with the current of dialyzate real-time continuously, and so causing to match somebody with somebody liquid every time all needs
Cleaning treatment carried out to equipment, and disposably prepare the resting period that more dialyzate extends dialyzate, easily gone out
Existing pollution hidden trouble.
