Cryoprecipitated antihemophilic factor preparation device
Technical field
The present invention relates to Cryoprecipitated antihemophilic factor preparation device field, be specially a kind of Cryoprecipitated antihemophilic factor preparation device.
Background technology
Cryoprecipitated Antihemophilic Factors are isolated most blood plasma, and are solid-state component blood by the quick-frozen in 1h of remaining cold insoluble matter after referring to and adopting specific method the fresh frozen plasma in preservation period to be melted at 1 DEG C ~ 6 DEG C.Cryoprecipitated Antihemophilic Factors are mainly used in inpatient with haematological diseases, such as congenital or acquired afibrinogenemia, congenital or acquired blood coagulation factor VIII deficiency disease, von Willebrand disease, children and light-duty grownup's hemophilia A etc.Cryoprecipitated Antihemophilic Factors from whole blood, isolate fresh frozen plasma by blood collecting and supplying unit, and then prepare from fresh frozen plasma.The quality of Cryoprecipitated Antihemophilic Factors and the standardization of whole preparation process and stdn closely related.At present, the preparation process of Cryoprecipitated Antihemophilic Factors in blood station mainly still adopts manually-operated method, causes the quality product prepared to be difficult to reach the standard of national requirements, and production efficiency is low, time-consuming effort.
The preparation of existing Cryoprecipitated Antihemophilic Factors mainly contains two kinds of methods:
1.4 DEG C of refrigerator defrosting+centrifuging:
The fresh frozen plasma being frozen into solid state is put into 4 DEG C of refrigerators to leave standstill, allow it naturally slowly melt, about 15 hours, still have during a little rubble ice until basic thawing and take out, heavy centrifugal.Isolate upper plasma to transfering bag, lower floor's blood plasma and the white depositions of staying former bag are cryoprecipitate, reach standard by the capacity of Weighing control cryoprecipitate.
2.1 DEG C ~ 6 DEG C water-baths are thawed+siphonage:
The fresh frozen plasma being frozen into solid state is put into the water being chilled to 1 DEG C ~ 6 DEG C in advance, the blood plasma of thawing oozes transfering bag by syphonic effect, and white depositions remaining in former bag is cryoprecipitate.Standard is reached by the capacity of Weighing control cryoprecipitate.
Wherein publication number is that CN102389592A uses water-bath freezing process and siphonage to be prepared, it adopts two cover weighing systems, the weight (namely going up weighing system) of fresh frozen plasma of weighing respectively and flow out to the real-time weight (namely descending weighing system) of transfering bag, forms siphon by peristaltic pump air-discharging.Because blood plasma cannot be weighed in water, so need a kind of lifting device first " upper weighing system " lift-off water surface, then weigh, then blood plasma is fallen in backwater thaw.
Secondly also have a publication number to be its use frozen air freezing process of CN104623748A, therefore there is the device such as blower fan, airduct.
The technical disadvantages of the following aspects that above-mentioned disclosed patent exists has:
One, owing to have employed the method that two cover system two steps are weighed, weigh to fresh frozen plasma and transfering bag respectively.Weighing of fresh frozen plasma must be carried out more than the water surface, needs again to put back in water to thaw, so realize with lifting device after having claimed.And the running and comparing of lifting device is time-consuming.The more important thing is, the setting of lifting device, cause the preparation work of cryoprecipitate can only carry out (a collection of at present can only prepare 15 bags) by the gross, as long as there is wherein one bag of cryoprecipitate not yet to prepare, all required etc. to be done after, just can carry out the preparation work of next batch cryoprecipitate, this is also the factor causing working efficiency not high.
Two, the setting of peristaltic pump makes the conduit between blood bag be pullled in wriggling process of being everlasting, and needs operator to keep and aside observes, pull back, otherwise cause conduit rupture by by the conduit pullled, very dangerous.
Three, whole operating in cabinet completes, and causes whole set equipment volume to be doted on greatly like this.Be provided with two cover refrigeration systems, a set of for the air cooling in cabinet, a set of to the water refrigeration in water bath.And air cooling role in cabinet is little, makes power double on the contrary, cause the waste of electric energy in a large number.
Four, the air thawing method preparation time adopted is very long, more than 10 hour, cannot promptly prepare.An equipment can only be prepared a collection of in one day, cannot realize the object of preparation in enormous quantities.And cryoprecipitate quality product prepared by air thawing is not high, thrombin meeting is wherein inactivation because preparation time is long.Wind after refrigeration can cause a large amount of energy waste by in/out air tube, and can very out of true by the homo(io)thermism that the refrigeration of wind and heating realized to blood plasma unfreezing.Generally, air thawing legal system belongs to filtering technique for cryoprecipitate.
