Outside the deficiency for the said equipment; The someone has proposed a kind of blood container that is used for optical photon therapy at present, and this blood container comprises blood. reservoir, buffering cup, oxygen discharging tube, Y tube road, and oxygen discharging tube connects blood. reservoir through the buffering cup; One end in Y tube road connects blood. reservoir; The other two ends in Y tube road, wherein an end is for irritating the blood vessel end, and the other end is the oxygenation pipe end.During use, take blood to inject blood. reservoir, irritate the blood vessel end with closed with covers through irritating the blood vessel end.Blood. reservoir is put to blood therapeutic instrument, open oxygen discharging tube, oxygenation pipe end and oxygen cylinder oxygenation pipeline are connected, and decontrol the oxygen cylinder valve, the beginning oxygenation.Start blood therapeutic instrument blood in the blood. reservoir is carried out the light quantum processing; When the change of rocking of producing of machine and oxygen flow, the quilt in the buffering cup of the blood in the blood. reservoir is slowed down, and returns in the blood. reservoir; Prevent spilling of blood, increased the time of blood contact oxygen.After finishing dealing with, close blood therapeutic instrument, close oxygen, blood. reservoir is taken out in blood therapeutic instrument, whole process is accomplished.Though this blood container has very great help for the processing of blood; But, in the process of blood. reservoir pumping blood, because the liquid level in the blood. reservoir can't be observed outside bag; Therefore; The blood amount of charging into of uncontrollable blood. reservoir, too much charging into can cause blood through cushioning the outside that cup and oxygen discharging tube spill into blood. reservoir, and very few charging into can cause not reaching instructions for use.
Summary of the invention
The control device and the method that the purpose of this invention is to provide a kind of light quantum blood container; The present invention detects the liquid level in the blood. reservoir through liquid level detector; Through the control of controller, make the liquid level in the blood. reservoir reach required liquid level to electromagnetic valve.
The technical scheme that realizes the object of the invention is following:
The control device of light quantum blood container comprises a liquid level detector that is installed in the blood. reservoir, and this Level Detection meter is used for detecting the blood that fills into blood. reservoir;
And being installed on first electromagnetic valve of irritating on the blood vessel, this first electromagnetic valve is opened or is cut off to the blood. reservoir pumping blood;
And being installed on second electromagnetic valve on the oxygen catheter, this second electromagnetic valve is opened or is cut off to the blood. reservoir delivering oxygen;
And a controller that is connected with liquid level detector, this controller receives the signal of telecommunication that comes from liquid level detector, after calculating, sends the signal that first electromagnetism turn-offs and second electromagnetic valve is opened;
And be connected in first driving amplifier between first electromagnetic valve and the controller;
And be connected in second driving amplifier between second electromagnetic valve and the controller.
The control method of light quantum blood container may further comprise the steps:
Step 1 detects the liquid level situation that fills into the blood in the blood. reservoir through liquid level detector, and detection case is sent to controller;
Step 2, controller calculates the signal that liquid level detector sends, and judges whether to turn-off first electromagnetic valve, and whether opens second electromagnetic valve; If controller sends signal, make first electromagnetic valve continue to open, second electromagnetic valve turn-offs, and then continues to the blood. reservoir pumping blood; If controller turn-offs first electromagnetic valve, second electromagnetic valve is opened, make oxygen delivery in blood. reservoir;
Step 3, step 2 controller are controlled second electromagnetic valve and are opened the time, and oxygen is contacted with blood fully.
Adopted such scheme, the present invention detects the liquid level in the blood. reservoir through liquid level detector, through the control of controller to electromagnetic valve, makes the liquid level in the blood. reservoir reach required liquid level.Avoided too much charging into can cause blood through cushioning the outside that cup and oxygen discharging tube spill into blood. reservoir, very few charging into can cause not reaching instructions for use.Make charging into of blood reach necessary requirement.
