Description
Technical field
The utility model discloses a kind of pen type safe blood-taking needle, especially disclose a kind of pen type safe blood-taking needle with over cap.
Background technology
Venous blood collection is widely used in clinical, and its Diagnosis and Treat for disease has great significance.Vein blood taking needle is used widely clinically in recent years, and compared to syringe venous blood collection, vein blood taking needle has the multiple advantages such as it is easy and simple to handle, safety and precise, time saving and energy saving, sterility is high, patient suffering is little.Blood taking needle is divided into pen type blood collection and hose type blood taking needle, generally believes that pen type blood collection has significant advantage when solving the problems such as blood coagulation at present.Whether successfully but in clinical, pen type blood collection also exists many problems, such as, after puncture, blood taking needle is interior without blood back, can not determine puncture problem.In order to solve without blood back in the rear blood taking needle of puncture, whether successfully can not determine puncture problem, domestic patent CN201420469955.7 discloses a kind of pen type safe blood-taking needle, thoroughly solves the problem that can't see blood back.But domestic patent CN201420469955.7 is in clinical, after blood sampling, although needle holder automatic rebounding enters in sleeve and makes puncture needle not leak outside under self stress, protection medical personnel preserve from, but puncture needle still has to come off and exposes the probability of urceolus in end processing sequences, the safety of related personnel can not be protected thoroughly, for solving this problem, there is mounting spring in blood taking needle at present, after blood taking needle is finished using, under the action of the spring, the puncture needle of blood taking needle can spring back in urceolus, thus reach the object of protecting from infection or stabbing.But in the assembling process of hemostix, spring assembling is complicated, is difficult to realize automated production, inefficiency.
Utility model content
This utility model overcomes the deficiency that prior art exists, and aims to provide a kind of pen type safe blood-taking needle with renovating.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of pen type safe blood-taking needle with renovating, and described blood taking needle comprises urceolus 1, lower needle holder 2, upper needle holder 3, puncture needle 4, collection blood pin 5, sheath 6, renovate 7, damping sleeve 8 and packing ring 9.Described urceolus 1 comprises button 11, annular slot 12 and upper needle holder mouth 13.Above described urceolus 1, front view is trapezoidal, and it is square type that sectional view is looked on the right side.Described button 11 is positioned at the upper side of urceolus 1.Described upper needle holder 3 comprises card key 31 and transparent windows 32.It is inner that described upper needle holder 3 is arranged on urceolus 1, through upper needle holder mouth 13 above it, leaks at urceolus 1 outside.Described card key 31 is installed on button 11 place.Be connected above lower needle holder 2 with below upper needle holder 3.Described puncture needle 4 is arranged on needle holder 3 center cavity, and described collection blood pin 5 is arranged on lower needle holder 2.Described damping sleeve 8 is enclosed within below collection blood pin 5.Described upper needle holder 3 is transparent windows 32 with the cavity of needle holder 2 intermediate formation.Described transparent windows 32 is in trapezoidal.Trapezoidal observation window 32 is beneficial to observation blood back more, decreases blood hold-up.
Describedly renovate 7 and be sleeved on above urceolus 1.Blood sampling complete, until puncture needle retraction spring into urceolus after, renovate 4 and can be buckled in needle holder mouth 13, avoid in use with use after cause infect and stab.
Described sheath 6 covers on outside puncture needle 4, is installed on needle holder 3.Packing ring 9 is installed with, to stop that needle holder does not eject from urceolus bottom in described annular slot 12.
This utility model compared with prior art has following beneficial effect:
1, safer, be applicable to automated production.Compared with prior art, this utility model is renovated owing to having installed additional, avoids after blood sampling completes, and puncture needle to retract in urceolus possibility out again, and avoids the use of spring, and thus use safer, assembling is simple, is applicable to suitability for industrialized production.
2, easy to use, be convenient to observe.This utility model observation window is positioned at the inner upper position of urceolus, and observation window is trapezoidal, decreases the hold-up of blood, decreases blood taking tube blood backflow amount, is thus convenient to observe.
