Description
Technical field
The utility model relates to the field of medical instrument technology, make when specifically, being a kind of clinically nursing staff blood sampling
Prevent needle from stabbing and avoiding the disposable safety type blood-taking needle for thering is blood to leak out after blood sampling.
Background technique
In the medical field, medical staff is acquired by various means, obtains Human Physiology, pathological information, for correct
It diagnoses the illness, wherein usually having following three kinds of approach for the acquisition of blood preparation: 1) subcutaneous blood sampling, for blood constituent
Simple differential counting detection, mostly using subcutaneous (solid or prismatic) blood taking needle；2) venous blood collection, can be in hematology, blood
Aetology and other related discipline indexs are detected in detail, using very extensively in clinic, use pen type or split type quiet more
Arteries and veins blood taking needle；3) arterial blood drawing detects aterial blood gas indexes following mostly in critical acute disease, and application is less, uses arterial blood drawing more
Special syringe is acquired.Acquisition and inspection to blood preparation, the purpose is to by analysis detection to blood constituent, obtain
The detection of bacteriology, virological infection level in blood blood component and blood is obtained, to understand Human Physiology and pathologic condition, or
Effect after understanding drug therapy, and the development of disease, prognosis are judged.
Common venous blood collection needle construction includes puncture needle, puncture needle tail end connecting conduit, and the conduit other end connects needle stand,
Needle stand outer end connects blood taking needle.In use, implementing venipuncture by puncture needle, after puncturing successfully, by blood taking needle through piercing
In vacuum blood collection tube, under the action of negative pressure, blood is drawn into heparin tube by puncture needle, conduit and blood taking needle；Repeatedly,
The acquisition of multitube time blood specimen can be achieved, blood sampling finishes, and extracts venipuncture needle, local hemostasis.
There is very big deficiency in actual use in existing blood taking needle, mainly safety is poor.Needle tip after blood sampling
Outside being all exposed to, there is the potential danger to other people unexpected injuries and infection.And the blood taking needle of tail portion does not have protective cap, blood sampling
After when extracting, be easy to cause needle to stab, while leaking out with blood, operator's skin easy to pollute, to increase medical care
Personnel are by the risk of blood infection, such as AIDS, hepatitis B be by the disease of blood born, to medical staff's body, psychology
Cause different degrees of injury.
Chinese patent 2014102168011 discloses a kind of safety-type vein blood taking needle, including venous blood collection needle assemblies, with
