Purpose..
When acquiring blood, main controller controls air pump 15 starts to export negative pressure, and pressure size leans on system pressure detector 13
It detects in real time, meanwhile, master controller handles the pressure detected from blood donor's pressure detector 4 in real time, is pressed according to blood donor
The size of power, master controller constantly quickly adjust the size that air pump 15 exports negative pressure.I.e. according to the size of blood donor's pressure come
The speed of adjustment acquisition blood is acquired with most suitable acquisition blood flow velocity, prevents blood donor from occurring uncomfortable.
When acquiring blood, blood needs addition anti-coagulants to prevent from solidifying, and the dosage of anti-coagulants cannot be excessive, if anti-freezing
Use ratio of the agent kind type difference when acquiring blood is also different.The present invention devises a set of control anti-coagulants dosage thus
Method：First, it is 1 comprising a size in the mating disposable infusion utensil of acquisition hematological system of the invention：16
Three-way connection 22.Secondly, when anti-coagulants and blood proportioning are 1：When 16, the pressure in anti-freezing agent container will be kept with system pressure
Unanimously.Finally, if it is not 1 that anti-coagulants is matched with blood：When 16, then the pressure value calculation formula in anti-freezing agent container is：
Ratio/16 are matched in system pressure * settings, such as：Anti-coagulants proportioning is set as 1：15, when system pressure is -50mmHg, then anti-freezing
Pressure value in agent container is：- 50*15/16=-46.875mmHg.
When acquiring blood, centrifuge 18 is in operating condition, and the blood constituent entered in Centrifuge Cup is centrifuged.
When acquiring blood, when anti-coagulants is used up, 2 output signal of anti-coagulants air detectors changes, and master controller is known
Not prompting user processing afterwards.
When acquiring blood, blood plasma claims sensor 12 to measure the weight for having acquired blood constituent in real time, and exports to main control
Device.
When acquiring blood, the detection alms bowl photoelectric sensor 19 and haemocyte detector 9 of collecting blood constituent are monitored, when
When collection blood constituent changes, alms bowl photoelectric sensor 19 or 9 output signal of haemocyte detector change, master controller
Corresponding actions are performed after identification.
When acquiring blood, blood donor's valve 7 is in opening state, brine valve 9 is closed, blood plasma valve 11 is in and opens
State.Whether there is air in blood donor's air detectors real time monitoring pipeline.
Also transfuse blood liquid when, main controller controls air pump 15 start export positive pressure, pressure size lean on system pressure detector 13
It detects in real time, meanwhile, master controller handles the pressure detected from blood donor's pressure detector 4 in real time, is pressed according to blood donor
The size of power, master controller constantly quickly adjust the size that air pump 15 exports positive pressure.I.e. according to the size of blood donor's pressure come
The speed of adjustment also blood transfusion liquid, it is also defeated to carry out with most suitable also defeated blood flow velocity, prevent blood donor from occurring uncomfortable.
Also transfuse blood liquid when, also had an intravenous drip of physiological saline to blood donor according to brine set by user also throughput rate, the speed of also defeated brine
Degree, dosage are controllable, the method that the present invention devises a set of control salt water consumption and also defeated salt velocity：First, saline container
When keeping suitable difference in height, also defeated brine with blood donor site of puncture, blood plasma valve 11 is closed, and brine valve 9 is opened, blood donor's valve
7 open, and brine is flowed by dead weight in blood donor's body.Secondly, the mating disposable infusion device of acquisition hematological system of the invention
Comprising a flow regulator 30 in tool, for adjusting salt water flow velocity manually.Finally, brine also throughput rate by brine weighing device into
Row measures, it is ensured that also defeated salt water meets user's setting value.
Also transfuse blood liquid when, centrifuge 18 is in halted state, and blood donor's valve 7 is in opening state.Also transfuse blood liquid when, brine
When using up, 8 output signal of blood donor's air detectors changes, prompting user processing after master controller identification.Blood donor is empty
Whether there is air in gas detector 4,5 real-time signal piping of blood donor's air detectors, once it is also defeated to find that air stops immediately,
And blood donor's valve 7, brine valve 9,11 Close All of blood plasma valve, system send out alarm signal, prompt user's processing.
Basic principle, main feature and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent defines.
