Description
Technical field
The present invention relates to a kind of blood storage system, particularly relate to a kind of blood storage system and method based on REID.
Background technology
Blood is stored in blood bank usually, by medical institutions, blood station or Red Cross's keeping, uses when transfusing blood in order to needs person.Due to uncertain to the demand of blood clinically, the blood model of needs or the type of component blood also differ, so prolongation blood and the deepfreeze technology of component blood shelf-life receive increasing concern.
Blood refrigerating can prevent from solidifying, ensure nutrition needed for cell metabolism, extend in blood the life-span of body outside human body, ensure to be defeated by patient after can play corresponding function.But because the feature of various haemocyte body is different, the method for preservation is also different, and storage life is also different.
At present, whole blood and red cell preservation can preserve 35 days in 4 ± 2 DEG C; Blood platelet is stored in special bag, and in 22 ± 2 DEG C, also constantly vibration, can preserve 5 days; FFP can preserve 1 year under Cryogenic Conditions below-20 DEG C.
Existing deep cooling cold storage plant is manual operation, needs workman manually to enter refrigerator and takes out blood.Be accessed in manually on blood administration and have very large drawback.First also will cause producing heat interchange between freezer and the external world, certainly will refrigerating capacity be increased, and increase energy resource consumption, also have adverse effect to the storage of blood.Secondly, blood storage there will be significant deficiency in information transmission He in information processing manually, as information errors, by the model of blood, quantity misregistration, deposit wrong position or get wrong blood bag, information processing error for another example, does not get blood according to first depositing the principle of first getting, cause unnecessary overstocked expired of blood, etc.
In recent years, the high speed development of message area and automatic field, brings the technology of many advanced persons.Wherein REID is exactly newly enter to rise and a kind of automatic identification technology got the nod rapidly.
Radio-frequency (RF) identification (RFID) technology is a kind of non-contact automatic identification technology realized based on radio frequency principle.The most basic radio-frequency (RF) identification (RFID) system consists of the following components: electronic tag, read write line and read write line Upper system.The principle of work of radio-frequency (RF) identification (RFID) system is as follows: read write line is by the radiofrequency signal of emitting antenna scattering certain frequency, when electronic tag enters emitting antenna perform region, respond to this radiofrequency signal and produce induction current, and therefrom extract energy activated circuit own; The electronic tag being in state of activation returns the carrier signal of the information that need send with himself coding etc. as answer signal by the transmitting antenna that label is built-in; System acceptance antenna receives the carrier signal that electronic tag returns, and is returned to read write line through antenna adjustments device; Be sent to backstage main system after the signal that read write line demodulation code receives to filter and certification; The information that main system reception read write line transmits judges the legitimacy of this electronic tag according to logical operation, and handles accordingly according to different set or send the action of command signal control topworks.
In recent years, developing rapidly and widespread use of REID, made market creates the multiple new technology that combines with it and new product.The typical apply of REID mainly contains logistics and supplies management, manufactures and assembling, aviation luggage process, mail/fast freight parcel process, document tracking/library management, animal identification identifies, motion timing, access control/electronic entrance ticket, road automatic charging etc.Rfid system automatically identifies destination object by radiofrequency signal and obtains related data, and the work that identifies is without the need to manual intervention, and RFID technique identifiable design moving object simultaneously also can identify multiple label simultaneously, is not afraid of oil stain, contamination by dust etc.Have that the waterproof not available for bar code, antimagnetic, high temperature resistant, long service life, reading distance are large, data can encrypt, store the advantages such as data capacity is larger, storage information can be changed on label.
In blood storage apparatus field, if rfid system can be combined with automatic technology, RFID noncontact is utilized automatically to identify and powerful information carrying capacity, make staff without the need to stepping into storehouse, realize automatic blood bag warehouse-in by automated machine conveyer to pile up, automatically getting blood becomes possibility; In conjunction with database information system, also can strict guarantee blood bag first-in first-out, and the stock-taking of robotization, thus greatly improve the efficiency of blood storage process.
