Description
Technical field
The invention belongs to technical field of medical instruments, particularly relate to the anticoagulant vacuum blood taking needle of medical disposable hard connecting band collection container and blood-letting mouth.
Background technology
China's tradition rigid connecting type blood taking needle has following shortcoming at present:
1, traditional rigid connecting type blood taking needle: during clinical blood sampling easily when moment thrombosis and haemolysis occur and particularly suffers from certain disease (as diseases such as hyperlipidemia) patient in blood drawing, blood flows out the external blood coagulation phenomenon that promptly takes place, and thrombosis stops up blood collection needles easily influences quality inspection.
2, traditional rigid connecting type blood taking needle does not link to each other with vacuum test tube, needs medical worker's connections when drawing blood operation such as nurse.Traditional design makes medical worker such as nurse increase operation link when blood drawing; Increase the probability of makeing mistakes; Increase workload; Be unsuitable for clinical blood drawing operation a large amount of, quick, that concentrate.
3, do not have anticoagulant in traditional rigid connecting type blood taking needle, contain anticoagulant, so after the clinical blood drawing, need put upside down mixing (blood combines with anticoagulant is better for convenience) immediately 5-8 time at vacuum test tube.
4, packaging material are too much, are unfavorable for environmental protection and reduce medical waste.
5, price height increases national medical insurance.
6, the traditional vacuum blood taking tube does not have secondary blood-letting mouth, may the read data failure during machine test on the blood sample in the whole blood taking tube or the Clinical Laboratory personnel think and be necessary duplicate test, and at this moment because the detection machine probe enters the blood sample in the whole blood taking tube, cause the homogeneous tube blood sample to pollute, go bad, blood samples of patients be need extract again, patient suffering and national medical insurance burden increased; The waste resource; Increase medical waste.
7, because the traditional vacuum blood taking tube uses the variety classes anticoagulant to tackle corresponding inspection item, so can't the separation of blood sample, even the purpose that secondary blood-letting mouth can not reach general detection is set, so in case blood sample goes wrong, or when query appearred in testing result, when maybe needing to increase inspection item, just can't carry out any detection and test once more.
8, owing to not adding any anticoagulant in traditional blood taking needle and not linking to each other, so anticoagulant is added in the vacuum test tube with vacuum test tube.The tradition anticoagulant mostly is every kind of chemicals of chemicals can only be at specific test item, heparin, sodium citrate, potassium oxalate, Na
2EDTA, K
2Traditional anticoagulant such as EDTA can not replenish mutually, can not exchange.Even so on blood taking needle, add heparin, sodium citrate, potassium oxalate, Na
2EDTA, K
2Anticoagulant such as EDTA, do not have in all senses yet and also can make troubles, increase misery (if on traditional blood taking needle, add traditional anticoagulant, patient's inspection item just need be more than 2 kinds) for the patient by many blood taking needles that the add different anticoagulant veins that puncture for clinical blood drawing check.
9, be inconvenient to add needed other additives of Clinical Laboratory.
The People's Republic of China's " Chinese pharmacopoeia version in 2005, first one, the 57th page of record " Hirudo (HIRUDO) ", this product is the dry all of Hirudinidae animal whitmania Whitmania pigra Whitman, Hirudo Hirudo nipponica Whitman or Folium Salicis Babylonicae Hirudo Whitmania wranulata Whitman, summer, Qiu Erji catch, scald extremely with boiling water, dry or the low humidity drying.Concoct: Hirudo is cleaned, cutting, drying.Scald Hirudo: get water purification trematodiasis section, water to little with Pulvis Talci according to the method for scalding and heave.Function with cure mainly: removing blood stasis, removing blood stasis stimulates the menstrual flow.Be used for the blood stasis amenorrhea, injury from falling down.
