Carry out real-time detection, meanwhile, the pressure that master controller real-time processing is detected from blood donor's pressure detector 4 is pressed according to blood donor
The size of power, constantly quickly adjustment air pump 15 exports the size of negative pressure to master controller.Size i.e. according to blood donor's pressure come
The speed of adjustment collection blood, is acquired with most suitable collection blood flow velocity, prevents blood donor from occurring uncomfortable.
During collection blood, blood needs to add the anti-coagulants prevent solidification, and the consumption of anti-coagulants can not be excessive, if anti-freezing
The different use ratios when blood is gathered of agent kind type are also different.For this utility model devises a set of control anti-coagulants
The method of consumption：First, a size is included in the supporting disposable infusion utensil of collection hematological system of the present utility model
It is 1：16 three-way connection 22.Secondly, when anti-coagulants and blood proportioning are 1：When 16, the pressure in anti-freezing agent container will be with system
Pressure is consistent.Finally, if anti-coagulants is not 1 with blood proportioning：When 16, then the pressure value in anti-freezing agent container is calculated
Formula is：Ratio/16 are matched somebody with somebody in system pressure * settings, for example：Anti-coagulants proportioning is set as 1：15, when system pressure is -50mmHg,
Pressure value so in anti-freezing agent container is：- 50*15/16=-46.875mmHg.
During collection blood, centrifuge 18 is in operating condition, and the blood constituent entered in Centrifuge Cup is centrifuged.
During collection blood, when anti-coagulants is used up, the output signal of anti-coagulants air detectors 2 changes, and master controller is known
Not prompting user treatment afterwards.
During collection blood, blood plasma claims sensor 12, and measurement has gathered the weight of blood constituent in real time, and exports to main control
Device.
During collection blood, the detection alms bowl photoelectric sensor 19 and haemocyte detector 9 for collecting blood constituent are monitored, when
When collection blood constituent changes, alms bowl photoelectric sensor 19 or the output signal of haemocyte detector 9 change, master controller
Corresponding actions are performed after identification.
During collection blood, blood donor's valve 7 is closed in open mode, brine valve 9, blood plasma valve 11 is in and opens
State.Whether there is air in blood donor's air detectors monitor in real time pipeline.
Also transfuse blood liquid when, main controller controls air pump 15 start export malleation, pressure size lean on system pressure detector 13
Carry out real-time detection, meanwhile, the pressure that master controller real-time processing is detected from blood donor's pressure detector 4 is pressed according to blood donor
The size of power, constantly quickly adjustment air pump 15 exports the size of malleation to master controller.Size i.e. according to 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, according to user set salt solution also throughput rate also had an intravenous drip of physiological saline to blood donor, the speed of also defeated salt solution
Degree, consumption are controllable, the method that the utility model devises a set of control salt water consumption and also defeated salt velocity：First, salt solution
When container keeps suitable difference in height, also defeated salt solution with blood donor site of puncture, blood plasma valve 11 is closed, and brine valve 9 is opened, and is donated blood
Member's valve 7 is opened, and salt solution is flowed into blood donor's body by deadweight.Secondly, collection hematological system of the present utility model is supporting once
Property delivery device in include a flow regulator 30, for manually regulation salt water flow velocity.Finally, salt solution also throughput rate claims by salt solution
Refitting is put and is measured, it is ensured that also defeated salt water meets user's setting value.
Also transfuse blood liquid when, centrifuge 18 be in halted state, blood donor's valve 7 be in open mode.Also transfuse blood liquid when, salt solution
When using up, the output signal of blood donor's air detectors 8 is changed, and user is pointed out treatment after master controller identification.Blood donor is empty
Whether there is air in gas detector 4, the real-time detection pipeline of blood donor's air detectors 5, once it is also defeated to find that air stops immediately,
And blood donor's valve 7, brine valve 9, the Close All of blood plasma valve 11, system send alarm signal, user is pointed out treatment.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, the utility model can also on the premise of the utility model spirit and scope are not departed from
There are various changes and modifications, these changes and improvements are both fallen within the range of claimed the utility model.The utility model will
Protection domain is asked to be defined by appending claims and its equivalent.
