Description
Technical field
The present invention relates to a kind of armarium, particularly a kind of blood constituent safely and efficiently that is applied to component blood collection field feeds back, acquisition control device.
Background technology
At present, human body is donated blood and is still the main source of medicinal blood.When donating blood, often only need certain or certain several specific blood component, for example blood plasma, platelet, erythrocyte etc., and other compositions can feed back to the blood donor are with the waste of avoiding blood resource and reduce the untoward reaction of transfusing blood.Therefore, donate blood technology in the modern times, adopt blood component to separate the method for gathering more, promptly the separation of whole blood of being gathered out by the blood donor becomes different compositions, and the composition that needs is taken out, then the composition blood that is left is fed back to the blood donor.
Existing blood component separator (as CS-3000 and NGL XCF-3000 blood component separator) is not owing to feed back container and two position is controlled conversion equipment automatically, the Hui Shu ﹑ of blood constituent separates, gathers respectively, is interrupted and carries out, and can not carry out the separation of blood constituent simultaneously when unwanted blood constituent feeds back to the blood donor.
Summary of the invention
In view of present blood recovery, to gather be respectively, be interrupted and carry out, troublesome poeration, the present situation that efficient is lower the objective of the invention is to design that the blood constituent that a kind of safe, efficient, blood recovery, collection uninterruptedly carry out feeds back, acquisition control device.
The present invention be a kind of safe, efficiently blood constituent feed back, acquisition control device, comprise feed back pump, feed back pump line, blood sampling pump and blood sampling pump line, it is characterized in that having on the control box, under the control box, the high and low level sensor of ultrasound wave, frame, blood sampling pump discharge flexible pipe, unwanted blood constituent flexible pipe, time controller, hose coupling and casing; Adopt transparent polymer material to be welded as a whole down with control box on the control box, form the feedback container and the multiplexer channel of sealing, each passage and feedback pump line, unwanted blood constituent flexible pipe, blood sampling pump line, the corresponding connection of blood sampling pump discharge flexible pipe, and be connected with hose coupling, form the medical disposable material global facility of sealing, be installed on the frame, frame becomes the 45o angle with horizontal plane, and the probe of high and low level sensor fits tightly respectively with under the control box by pilot hole corresponding on the frame; The series connection of the sensing circuit of high and low liquid level ultrasonic detector, and be connected the feedback pump with the control circuit series connection back of time controller, guarantor's circuit is opened in the sensing circuit setting of high liquid level ultrasonic detector.
Medical disposable material global facility is the medical disposable material of sealing sterilization, forms blood constituent jointly with frame, feedback pump, blood sampling pump, high and low liquid level ultrasonic detector and feeds back, gathers cycler.
Operation principle of the present invention is as follows:
Follow the separation and the collection of blood constituent, unwanted blood constituent enters through the input flexible pipe and feeds back in the container (Fig. 2 thick line scope) in the control box, when blood reaches highly when surpassing the probing wave width for H-number (by Fig. 6-to Fig. 5) in low liquid level, because the outer air face is vertical with ultrasound wave incident, ultrasound wave returns by former road, and the low level sensor of ultrasound wave receives behind the ultrasound wave of reflection the contacting with programmed element; Unwanted blood constituent continues to flow into and feeds back in the container, when blood reaches highly when surpassing the probing wave width for H-number in high liquid level, in like manner, ultrasound wave returns by former road after vertically running into the outer air face, ultrasonic wave height level sensor receives behind the ultrasound wave of reflection the contacting with programmed element---start and feed back pump, give the blood donor with the blood recovery that feeds back in the container; When blood recovery when high level sensor is surveyed less than the ultrasonic signal that returns, the contact of programmed element is disconnected, electric current is protected circuit and is passed through from opening, and still keeps feeding back the pump running; The pump of meanwhile taking a blood sample running---when unwanted blood constituent feeds back to the blood donor with a part of blood from the joint again pump the feedback of blood and blood constituent are separated carry out simultaneously to separating tank, it is uninterrupted to keep blood constituent to separate continuously.When the low level sensor of ultrasound wave highly for H-number above the probing wave width detection in the feedback container during air, because air/blood interface becomes the 45o angle with ultrasound wave incident, ultrasound wave is pressed 90o reflection (Fig. 6), detector does not receive the ultrasound wave of reflection, the contact of programmed element is disconnected---cutting off feeding back pumping source, blood recovery stops.Break down as the low level sensor of ultrasound wave in this process, do not cut off feeding back pumping source, time controller still can cut off the feedback pumping source then, realizes double protection functions, avoids air to pump in blood donor's body.Feeding back after pumping source is cut off, the blood sampling pump still keeps running, with blood from blood donor's pump to separating tank, make the separation of blood constituent keep continuously uninterrupted.Unwanted blood constituent enters through the input flexible pipe and feeds back in the container--enter next cyclic process.
This device has following function:
1, safety: adopt dual security protection, even avoid air when blood recovery, to pump into human body--under the situation that the ultrasonic detector single factors lost efficacy, time controller still can cut off the feedback pumping source, effectively protects the safety of blood donation personnel.
2, high efficiency: blood constituent Hui Shu ﹑ Cai Ji ﹑ separates and keeps seriality, has significantly shortened the component blood acquisition time.Be reduced to 68 minutes, and improved the comfortableness of blood donation personnel in 115 minutes that will gather 5.0 * 1011/ bags of dose double platelet.
3, reduced the waste of blood source: the feedback container of uninterrupted continuous firing and small size makes blood residual few.
