Description
Technical field
The utility model relates to field of medical technology, are especially a kind of singlehanded pull-back safe blood-taking needle.
Background technique
Currently, blood taking needle be it is a kind of use very common medical apparatus, due to using frequently, dosage it is big, thus market
On there is the different blood sampling apparatus of many structures.
It is found by retrieval, the utility model of patent No. CN201220172268.X discloses that a kind of visual blood back is two-way to be adopted
Blood needle, by blood taking needle sheath, vein needle shield, blood sampling needle assemblies and intravenous needle assemblies form, blood sampling needle assemblies by blood-collecting needle tube,
Blood sampling needle stand and butyl Capsule composition, intravenous needle assemblies are made of vein needle tubing and vein needle stand, it is characterised in that: blood sampling needle stand
It is made with vein needle stand of transparent or semitransparent material, blood sampling needle ring shape sheath and vein needle ring shape sheath are close in opposite directions
It is nested together, forms sealed internal chamber.Blood-collecting needle tube and vein needle tubing are not directly connected intercommunication.A little venous blood of venipuncture
Enter sealed internal chamber by vein pressure, so as to clear view to blood back, is punctured successfully with determination.
A kind of one-way reverse-blocking safe blood-taking needle of the disclosure of patent No. CN201210323237.4, it is characterised in that: packet
Butt end needle tubing, venipuncture end needle tubing and the attachment device between butt end needle tubing, venipuncture end needle tubing are included, is connected
One-way reverse-blocking flow structure is equipped in device.This blood taking needle is structurally reasonable, by the way that one-way reverse-blocking flow structure is arranged, can prevent vein
Blood countercurrently enters human vein blood vessel from heparin tube in blood collection procedure, ensure that the safety of person of blood collecting；The needle handle of design
Safe lunge-proof device is constituted with the combination of venipuncture needle protective case, ensure that venipuncture end needle tubing does not pierce accidentally, protect medical care
Personnel play the role of safety blood taking.
The utility model of patent No. CN201420173162.0 discloses a kind of safe blood-taking needle comprising has saddle, soft
Pipe, staight needle, staight needle handle and syringe needle, the both ends of hose are connected to staight needle and saddle respectively, and staight needle handle is set to staight needle and hose
Junction, safe blood-taking needle further include having protective cover, protective case and handle；Fix and be connected to syringe needle, the other end in one end of saddle
It is connect with hose；Protective case is that both ends are equipped with opening, and protective case is movable to be sheathed on saddle and be close to saddle, the length of protective case
Degree is greater than the pattern length of syringe needle and saddle；At least one axial latasuture, handle and saddle phase are offered on the side of protective case
Fixed, handle extends to outside protective case from latasuture；The internal diameter of protective cover is greater than the outer diameter of vacuum tube, and protective cover covers at outside staight needle
And it is fixed with staight needle handle spiral.It is slided on needle stand by the way that saddle is arranged to cover syringe needle, so that the processing after blood sampling to syringe needle
Safety be substantially improved；The use for avoiding spring syringe needle reduces the pain of patient.
However, although these existing blood taking needles improve the correlated performance of blood taking needle from different aspect, there is also with
Lower shortcoming: the guide groove of currently used blood taking needle be it is open, puncture needle blocks needle point without object after use,
Puncture needle is easy to hurt healthcare givers from guide groove stretching and cause blood-borne.It is too thin that needle handle design is held simultaneously, and is not provided with anti-
Sliding function, lacks ergonomic design.The screw connection mode that uses is connect with needle holder in blood sampling needle stand, and when assembly is more taken
When, production cost is also high.
Also, existing recoil of spring formula blood taking needle, this is that high speed is rebounded, and can generate vibration, generate impact, blood grain meeting
Splashing is generated, false triggering is easy；
Moreover, other retraction type blood taking needles, needle essence is preceding drawing protection pipe to cover needle point, one-handed performance is unable to, in reality
It is related with medical staff's habit in the operation of border, accidental injury can be generated in actual operation.
Moreover, existing safe blood-taking needle is that with the hands will definitely increase needle forward action to be needle punched into when operating
It is dangerous.
