Consumptive material comprises three kinds of washing liquids (1 liquid, 2 liquid, 3 liquid) bag, frozen red cells blood bag, finished bag, waste fluid bag and many pipelines.Three kinds of washing liquid bags are communicated with first fork of blood pump 108 3 trouble interfaces separately by pipeline, pipeline is provided with control valve 101,102 and 103 separately; Frozen red cells blood bag and finished bag are communicated with second fork of blood pump 108 3 trouble interfaces separately by pipeline, pipeline is provided with control valve 104 and 105 separately, and the frozen red cells bag places one to shake up on the device 112; Waste fluid bag is by the junctions of pipeline connection blood pump 108 3 trouble interfaces, and pipeline is provided with control valve 109;
Infusion support is the support (can be 20cm as support length, the diameter of metallic rod can be 1cm) with a plurality of hooks of arranging straggly, and three kinds of washing liquids (1 liquid, 2 liquid, 3 liquid) bag, finished bag, waste fluid bag all can be suspended on this support.Support should be placed on the position near main frame.Be appreciated that infusion support is not an indispensable accessory of the present utility model, also can finish the suspension of above-mentioned various pipe, bag with the simple and easy hook that the scene can conveniently hang.
In the enforcement, controller 111 not only is electrically connected (representing to be electrically connected with dotted arrow among Fig. 1) startup and rotating speed with control centrifuge 110 with the motor of centrifuge 110, controller 111 also is electrically connected (representing to be electrically connected with dotted arrow among Fig. 1) with shaking up device 112, controls its frequency of oscillation and amplitude; Control valve on the pipeline is electromagnetic valve, and controller 111 is connected (among the figure not faithful representation) and controls their keying with these control valves; Controller 111 also is electrically connected (representing to be electrically connected with dotted arrow among Fig. 1) with the motor of blood pump 108, control its wriggling direction and flow velocity.The control circuit of controller can design according to above function introduction in the usual way, also can be with reference to the control circuit of the U.S.'s 215 type hemocyte washing machine.
In concrete enforcement, the apparent size of cabinet 10 can be 40 * 35 * 30 centimetres, and materials such as available engineering plastics or metal are made.
In concrete enforcement, the main effect of blood pump 108 is that cleaning mixture is pumped into the blood bag, fully is mixed into cell suspension with hemocyte, and the drive motors of peristaltic pump can be the CM1-23L20 (model) of cool muscle, and its rotating speed can be set.Because peristaltic pump adopts direct current generator, by regulating the voltage-regulation motor speed of supplying with motor, the peristaltic pump rotating speed is arranged on 5-300 milliliter/min usually, and under this set, washing 200 milliliters of erythrocytic times is 30-50 minute.When adding washing liquid, peristaltic pump wriggling direction from left to right, when the frozen red cells after the dilution enters centrifuge, peristaltic pump wriggling direction from right to left, behind the centrifuge washing, peristaltic pump pumps into waste fluid bag with waste liquid from left to right, and repeated centrifugation washing step repeatedly.After washing finished, peristaltic pump pumped into finished bag with the finished product erythrocyte from left to right.
(referring to Fig. 1) describes the Washed Red Blood Cells process below in conjunction with this utility model structure:
Frozen red cells bag (blood bag) put under 37 ℃ thaw, be placed on then and shake up on the device 112.Open system, controller 111 are opened and are shaken up device 112, frequency of oscillation 3Hz, 1.5 inches of amplitudes.This moment, valve 101 and 104 was opened, and blood pump 108 begins to start flows liquid from left to right, and flow velocity is approximately 25ml/min.Blood pump 108 is computation time by the control flow velocity, and after required amount of liquid all arrived the blood bag, controller 111 controls shook up device 112 time-outs and shake, and leave standstill 2 minutes.Valve-off 101 then, open valve 102, and controller 111 is opened and shaken up device 112, frequency of oscillation 3Hz, 1.5 inches of amplitudes.Blood pump 108 starts once more flows liquid from left to right, and flow velocity is approximately 150ml/min.Left standstill 2 minutes.So far, washing liquid 1 and washing liquid 2 enter the blood bag successively, have reduced the glycerol osmotic pressure.
Valve-off 102 is opened feed liquor valve 106, and blood pump 108 rotates from right to left, and liquid flow in the centrifuge 110 from right to left in the startup blood bag.Controller 111 orders about centrifuge work, and centrifuge is discharged to drain pipe by high speed centrifugation with supernatant, close feed liquor valve 106 this moment, open the control valve 109 on liquid valve 107 and the waste fluid bag pipeline, blood pump 108 rotates from left to right, supernatant is pumped out to waste solution channel flows into waste fluid bag.Valve-off 107 is opened valve 103, opens to shake up device 112, and frequency of oscillation and amplitude are the same, and blood pump 108 start liquid flow from left to right and flow into the blood bag, and flow velocity is approximately 150ml/min.After an amount of washing liquid 3 entered the blood bag, valve-off 103 was opened feed liquor valve 106, and blood pump 108 rotates from right to left, and liquid flow in the centrifuge 110 from right to left in the startup blood bag.Controller 111 orders about centrifuge work, the beginning centrifuge washing.Centrifuge is discharged to drain pipe by high speed centrifugation with supernatant, and close feed liquor valve 106 this moment, opens the control valve 109 on liquid valve 107 and the waste fluid bag pipeline, and blood pump 108 rotates from left to right, supernatant is pumped out to waste solution channel flows into waste fluid bag.Open valve 103 and valve 106, blood pump 108 starts flows liquid from left to right, and flow velocity is approximately 150ml/min, and washing liquid flows into centrifuge 110 in No. 3 washing liquid bags, centrifuge 110 work, beginning centrifuge washing and above-mentioned identical process output to supernatant in the waste fluid bag; Centrifugal repeated washing process like this 3 times.
Open feed liquor valve 106 and control valve 105 at last, control blood pump 108 rotates from left to right, makes the finished product erythrocyte of centrifuge 110 bottoms flow into finished bag.Washing process is finished.
In sum, this utility model adopts accurate peristaltic pump to replace the manual liquid feeding of 115 type blood washing machine, make whole washing process can realize automatization, simultaneously, with peristaltic pump from 215 type blood washing machine two be reduced to one, make washing process easier, step is simple, is convenient to operation; Wherein two external tappings with centrifuge link to each other with peristaltic pump by Multidirectional connector, thus make liquid feeding, effluent discharge and translate into every work such as product erythrocyte can along with peristaltic pump wriggle direction difference and realize.
