Description
Technical field
This utility model relates to the puncture of blood bag, is specifically related to a kind of blood bag puncture pigtail and twists into two parts mechanism.
Background technology
The problem of transfusion safety is more and more subject to the attention of numerous doctors and patients, through Transfusion Transmission disease, the existence of the virus such as especially various viral hepatitis, acquired immune deficiency syndrome (AIDS) in blood plasma, find there is HAV ~ HFV with the relevant virus of blood transfusion by research, SEN is viral in addition, TT is viral, HGV is viral, Protein virus (TSE), cytomegalovirus (CMV), Epstein-Barr virus, the mankind are addicted to T lymphocyte virus I type and II type (HTLV mono-I, II) etc.Due to the reason such as detection technique, window phase, accurately cannot detect in blood plasma whether there is these virus.By application blood products, the disease propagated is troubling especially, particularly the rapid spread of acquired immune deficiency syndrome (AIDS) and global propagation at present, and a lot of country is using the great state basic policy of prevention and corntrol HIV as national final and decisive juncture.How preventing the infected upper disease because of blood transfusion, is the problem that current blood transfusion medical science and clinical medicine and even various circles of society pay close attention to jointly.To fundamentally control and stop hematogenic infectious disease, except strengthening the detection to a series of blood born diseases, inactivation of viruses process can also be carried out to blood, just can accomplish transfusion safety.Blood-plasma virus killing by physics or chemical means, the structure of virus protein is damaged, and allows the virus that may exist in blood plasma lose infection, to cause a disease and fertility.In in the past 10 years, this technology is progressively promoted at home.Carrying out inactivation of virus to blood constituent is the most effective approach realizing safe transfusion, greatly reduces the probability of viral infection like this, for major contribution has been made in the blood transfusion of China and clinical practice.For preventing blood transfusion from spreading disease, clinical practice virus inactivated plasma is far-reaching and great to preventing Emperical Bayesian method meaning.
The connection of inactivation of virus blood bag and plasma bags mainly contains two kinds of modes: one is aseptic adapter, and one is aseptic puncture.Aseptic adapter connects, and because consumables cost is higher, usage quantity is relatively less, and great majority all adopt aseptic puncture to connect.
At present, aseptic puncture is all manual work from pulling out pin, twisting the overall processes such as cap, puncture, scanning.Operator one holds puncture pigtail, and another holds puncture needle, thrusts puncture pigtail certain depth.Manually carry out aseptic puncture, although technique mature and reliable, there is problem and the hidden danger of the following aspects:
1, the risk of occupational exposure
In a large number, high-frequency puncture may cause the risk of operator's occupational exposure.
2, the risk of blood plasma pollution
Manual operations requires very high to environment and operator's hand disinfection and puncture success rate.
3, operator's labor intensity is large
Need energy high concentration during operation, when puncture quantity is more, pull out pin, twist the operation labor intensity such as cap, puncture, scanning greatly, finger skin easily causes wearing and tearing and damage.
4, cannot implementation procedure record and control.
Therefore, develop a kind of compliant requirement, automatically carrying out pulling out pin, stubborn cap, puncture operation in clean environment, and have the full-automatic blood bag lancing system of automatic transport, scanning, collecting function, is the fundamental way overcome the above problems.
