Description

Multi-functionally adopt the blood exchange transfusion set

Technical field

This utility model relates to a kind of medical equipment, relates in particular to a kind of multi-functional blood exchange transfusion set of adopting who is used to gather blood.

Background technology

At present; There are following many deficiencies the national blood station widely used disposable blood exchange transfusion set of adopting of system: 1. adopt the blood exchange transfusion set and can only be used for blood sampling; Not having the function that keeps sample, is two complete isolating operations owing to take a blood sample and keep sample, and the operator can be before blood sampling or after the blood sampling; Give unique sign indicating number of donating blood to the blood donor; BIAO and BEN after respectively giving the blood bag simultaneously respectively and leaving and taking blood is pasted identical identify label (sign indicating number of donating blood), with realization three's concordance, but in the real work; Unavoidably can occur inconsistent situation (example: what occur when two people take a blood sample simultaneously intersects the setting-out and the stickup identify label mistake of intersecting) between BIAO and BEN that leave and take, blood and the blood donor, and cause the generation of mistake and accident because of anthropic factor causes; 2. possibly influence the capacity of blood bag inner blood when causing the blood waste easily; Leucocyte-removing is adopted and is tended to exist 7ml blood be wasted (because of filtering leukocyte, after female bag moves to the transfering bag, female bag will be dropped together with conduit with blood) between blood exchange transfusion set's blood taking needle to blood bag in the conduit; And can't utilize; Blood also has certain loss when the leukoreduction filter dish, when keeping sample (like bone marrow prepare) in increase, if artificially do not increase the deviation that collection capacity also possibly cause blood volume in the blood bag; 3. influence testing result; The general pattern that keeps sample is that the blood of adopting into the blood bag (with the abundant mixing of blood bag inner blood preservation liquid) through blood collection needles, in vitro under the action of negative pressure, is sucked blood in vitro through conduit in the blood bag; First BIAO and BEN is the conduit inner blood; Usually not diluted, but second, the 3rd BIAO and BEN of leaving and taking will diluted (need leave and take two BIAO and BEN) at least in the real work, possibly can influence the verity and the accuracy of testing result in various degree; 4. there is contaminated risk, existingly keeps sample, the blood sampling pattern is to have gathered earlier behind the blood specimen taken again, so; The blood that collects at first must flow in the blood bag earlier; Therefore, easily the residual antibacterial on the skin is brought in the blood taking bag, exist certain blood by the risk of germ contamination; 5. recheck that to examine flow process more loaded down with trivial details and dangerous, when BIAO and BEN need be rechecked when examining again, the department that the testing staff need arrive storing blood carries out the blood bag and looks for; And the blood in the extraction conduit detects once more, and program is complicated, and workload increases that (staff needs conduit is cut off; Be reentered into blood in vitro, simultaneously the supravasal yard label of donating blood torn, stick on the test tube and detect); Simultaneously, the conduit pigtail appearance of extraction is also checked the generation that carelessness causes mistake because of the people easily; 6. have the danger of occupational exposure, the staff is stabbed finger by blood taking needle easily, and in the process that keeps sample, staff's left hand is held test tube, and the right hand is held blood taking needle pinprick is gone into the block place of test tube, because area is less, is easy to stab hands and refers to; 7. be unfavorable for the clearance management of blood, because the controlling unit that keeps sample can't guarantee that 100% is correct, Ministry of Public Health is when issuing the blood station quality control procedure; For the mistake and accident of the BIAO and BEN inconsequent of controlling and find to keep sample, formulated blood and criticized the clearance control sequence, in order to implement batch to let pass operation; Artificially with the blood preparation of life period and space tight association, be established as a binding batch, have only when BIAO and BEN all in same batch all to be detected and confirm errorless after; Could let pass to the related blood of BIAO and BEN; Will make can delaying the clearance time of blood, under the situation nervous, can let pass as early as possible in order to make blood with blood; And the quickening detection speed also will increase the cost of detection; 8. be unfavorable for blood from blood donor's blood vessel to patient vessel's overall process effective monitoring and trace to the source; Taking a blood sample at present, keeping sample, give the sign indicating number of donating blood still is three different links hand-manipulated; Still can not realize real-time omnidistance computer management, so can not realize that blood products is in the effective monitoring of blood collecting and supplying overall process and reduce the risk that anthropic factor causes; 9. centralization detects and has certain risk; It is Blood Transfusion Services's Development Trend that centralization detects; But it can only be responsible for (rechecking again, inspection still detects with former BIAO and BEN) to the BIAO and BEN that detects; Can't guarantee between blood, BIAO and BEN, the blood donor under the very correct and consistent situation that there is certain risk in the testing result clearance blood according to BIAO and BEN.
