Description
Technical field
The present invention relates to a kind of single use anti-pricking wound type venous detaining needle.
Background technology
Using venous detaining needle is a new Materials of Nursing Techniques, and it the most progressively instead of traditional scalp draw point.Its transfusion advantage of more traditional scalp draw point is: the sleeve pipe of indwelling intravenous can indwelling time long, and be difficult to puncture blood vessel wall.The sleeve pipe of venous detaining needle has puncture needle to lead into human vein blood vessel, therefore after sleeve pipe punctures and puts in place, the puncture needle guided need to exit and abandon, in this process, the puncture person that nurse operation is the most easily rejected stabs, or has influence on the operation to remaining needle because fearing to stab.At present; many hospitals of China all using venous detaining needle as clinical care and the main tool for the treatment of; but being substantially all is the remaining needle of non-anti-pricking wound type; annual country need to be from the substantial amounts of anti-pricking wound type remaining needle of external import; the anti-pricking wound type venous detaining needle of main flow is after puncturing the successfully withdraw of the needle; needle point can reclaim in protection device, it is to avoid the puncture needle that nurse has just been abandoned in operation is stabbed and caused blood infection.The patent of invention that applicant has obtained is entitled: a kind of safety needle assembly (patent No.: 201420566186.2), it is capable of after entry needle is injected, by its anti-stab safety device, the needle point of entry needle is housed, prevent needle point from exposing, play the effect preventing prick into human body, but during specifically used, the elastic screens arm needing its elastic spacing one stretches in this limited impression, play position-limiting action, this entry needle is limited in this sleeve pipe, can not be moved along, (specifically checking mandate text) can not be moved backward, but once occur that elastic spacing one cannot limit the movement of entry needle in specifically used, the exposure of entry needle can be caused, in other words, its structure not possessing double insurance guarantees that entry needle is housed in needle stand.
Summary of the invention
Offer single use anti-pricking wound type venous detaining needle is provided, on the basis of the present invention retains existing remaining needle function, add Anti-stabbing safety device, automatic locking needle point when the Anti-stabbing safety device energy biopsy needle guide of the present invention exits, prevent needle point from exposing, be prevented effectively from medical personnel and be wounded by stabbing in operation and infected.
A further object of the present invention is to provide single use anti-pricking wound type venous detaining needle; the present invention stops the needle point of puncture needle to depart from anti-acupuncture protection set by anti-acupuncture folder and anti-pin barrier sheet; realize the effect that double protection needle point exposes, prevent the needle point of puncture needle from exposing prick into human body.
nullThe technical solution used in the present invention is: single use anti-pricking wound type venous detaining needle,Including puncture needle and for the needle point housing puncture needle the Anti-stabbing safety device preventing needle point from exposing,This Anti-stabbing safety device includes anti-acupuncture protection set、It is arranged on this anti-acupuncture protection set internal for stoping the needle point of puncture needle to press from both sides and be arranged on the internal anti-pin barrier sheet for stoping the needle point of puncture needle to stretch out of this anti-acupuncture protection set from this anti-acupuncture guarantor's guard trailing end from the anti-acupuncture that this anti-acupuncture guarantor's guard leading end stretches out,When the needle point of this puncture needle is taken in this anti-acupuncture protection set inside,When the needle point of this puncture needle being promoted toward the front end that this anti-acupuncture protection is overlapped by external force,By this anti-acupuncture folder, the needle point of this puncture needle is stopped and the spacing inside at this anti-acupuncture protection set,When the needle point of this puncture needle being pulled toward the rear end that this anti-acupuncture protection is overlapped by external force,Limited this puncture needle by this anti-acupuncture barrier sheet to continue to move to and by spacing for the needle point of the puncture needle inside at this anti-acupuncture protection set.
This anti-acupuncture sandwiched is equipped with the leading edge hole passed for this puncture needle, rear end perforation and the elastic arm of force, this elasticity arm of force contacts with the needle body of this puncture needle all the time and produces the elastic force being perpendicularly oriented to this puncture needle direction all the time, after this lancet puncture operation completes, the needle point of puncture needle is pulled until its needle point departs from this leading edge hole and enters the inside of anti-acupuncture protection set toward this anti-acupuncture protection set is internal, effect now by elastic arm of force elastic force, this anti-acupuncture folder run-off the straight, the needle point making puncture needle deviates this leading edge hole, the needle point making this puncture needle is not located on same level line with leading edge hole, press from both sides so that the needle point of this puncture needle cannot stretch out this anti-acupuncture by leading edge hole.
This anti-pin barrier sheet arranges the trepanning penetrated for puncture needle, and this puncture needle is convexly equipped with one and stops the needle point limiting section by trepanning near the position of needle point, by this anti-pin barrier sheet by spacing for the needle point of the puncture needle inside at anti-acupuncture protection set.
This anti-acupuncture folder includes top board, front end-plate and end plate, wherein, this front end-plate is connected to the front end of this top board, this end plate is connected to the rear end of this top board, it is overall that this elasticity arm of force and this front end-plate are connected to become one, this leading edge hole is arranged in this front end-plate, and the perforation of this rear end is arranged in this end plate.
This anti-acupuncture folder is additionally provided with the limiting plate that the needle point preventing puncture needle passes from the both sides of front end-plate, and this limiting plate and this elasticity arm of force are connected to become an entirety, and this limiting plate is provided with hole clipping.
This limiting section is, by the form of punching press, the needle body of puncture needle flattens the flat protuberance formed, and this anti-pin barrier sheet is round steel sheet.
The invention have the benefit that the present invention structurally includes puncture needle and for the needle point housing puncture needle the Anti-stabbing safety device preventing needle point from exposing, this Anti-stabbing safety device includes anti-acupuncture protection set, it is arranged on this anti-acupuncture protection set internal for stoping the needle point of puncture needle to press from both sides and be arranged on the internal anti-pin barrier sheet for stoping the needle point of puncture needle to stretch out of this anti-acupuncture protection set from this anti-acupuncture guarantor's guard trailing end from the anti-acupuncture that this anti-acupuncture guarantor's guard leading end stretches out, when the needle point of this puncture needle is taken in this anti-acupuncture protection set inside, on the basis of the present invention retains existing remaining needle function, add Anti-stabbing safety device, automatic locking needle point when the Anti-stabbing safety device energy biopsy needle guide of the present invention exits, prevent needle point from exposing, it is prevented effectively from medical personnel to be wounded by stabbing in operation and infected.
The present invention stops the needle point of puncture needle to depart from anti-acupuncture protection set by anti-acupuncture folder and anti-pin barrier sheet, it is achieved the effect that double protection needle point exposes, and prevents the needle point of puncture needle from exposing prick into human body.
