Description
Technical field
This utility model relates to a kind of remaining needle, belongs to technical field of medical instruments.
Background technology
In recent years, the sharp blade tip of the syringe etc. being contaminated by the blood due to medical worker thrust by mistake cause acquired immune deficiency syndrome (AIDS),
The danger of the infection of hepatitis virus etc. becomes problem.Then, people have invented following safety indwelling needle, wherein, are including
In the remaining needle molectron of interior pin and outer pin, in the case of without the interior pin after using is encapsulated cap body again, it is covered,
Prevent from thrusting by mistake, such as disclose following safety indwelling needle, after wherein thrusting, by pressing be arranged in remaining needle by
Button, is pulled into inside needle guard by spring by interior pin, is received in wherein.The secured location with release mechanism in the past
In pin, due to cover the needle point protection mechanism of interior pin extracted out from outer needle assembly must have receive overall in the size of pin,
Therefore the becoming large-sized of remaining needle itself.It addition, use the occasion of spring at needle point protection mechanism, due to the bias force of this spring
The pull-out force of interior pin is more than interior pin and the frictional force of needle point protection mechanism, therefore has power required when extracting interior pin out and increase, and makes
The problem that feel is deteriorated.Even if it addition, have in by protections such as needle point guard blocks in the case of pin, needle point is recognized from needle point
Protection mechanism is in prominent danger.Also having safety indwelling needle, lower section is closed with a through hole thin slice, by blood back hole on puncture needle
Portion flattens to be formed and expands, and makes needle point be hidden in covering, owing to this covering is provided above tool sealing of hole springy ferrum
Sheet, shell fragment continues to form frictional force between draw point during puncture needle exits.Make the problem that feel is deteriorated.And this structure is multiple
Miscellaneous assembly technology requires height, the problem causing cost.

Would fit snugly within the protection set pull-out in indwelling needle chamber, wherein the soft set of plastics is possible not only to be accommodated in remaining needle needle handle and guarantor easily
Between sheath in space, and whole puncture needle can be wrapped up, relatively reliable guarantee blood cannot splash.
Preferably, above-mentioned puncture needle protection set is the medical cork of cylindricality with through hole.The most above-mentioned puncture needle protection set
Via bottoms there is a soft sealing of hole thin slice, now, this sealing of hole thin slice is cone-shaped slice upwardly, or above-mentioned wears
The bottom of pricker protection set is the taper bottom plug being formed and being available for the pin hole that puncture needle passes through, and utilizes puncture needle to lead to from taper bottom plug
After hole is exited, there is position deviation, when needle point runs into puncture needle needle point with automatic in protection set bottom through-hole under gravity
Automatically slip on taper bottom surface during taper surface, cause needle point cannot put through hole with protection and be again directed at, can be further ensured that and wear
Pricker needle point will not stretch out after exiting indwelling needle cavity from puncture needle protection set again, it is ensured that puncture needle needle point can be the most hidden
It is hidden in puncture needle protection set.
Preferably, the via top of above-mentioned puncture needle protection set is provided with a tool resilient sealing of hole thin slice, this sealing of hole thin slice
Can be to be shaped in puncture needle to protect sheath tip, it is also possible to being that sealing of hole thin slice is fixed on puncture needle guarantor's sheath tip, this is thin
Protection set is formed a closely sealed cavity by sheet, can be prevented effectively between puncture needle needle point and blood back bore portion the blood back cavity formed
In remained blood splash out.
This utility model is provided with telescopic connecting-piece structure owing to using between puncture needle needle handle and puncture needle needle handle,
During puncture needle exits, make puncture needle protection set with puncture needle needle handle between have certain distance poor so that puncture needle and
Protection set exits from remaining needle simultaneously, and tip portion can reliably be hidden in puncture needle protection set, reliably ensures to wear
Pricker needle point will not sting medical personnel by mistake, prevents needle point from thrusting the Hematogenous infection caused by mistake.Especially, the puncture needle protection set end
Portion arrange cone-shaped slice or bottom plug, after utilizing puncture needle to exit from through hole protection set central hole under gravity with wear
Pricker needle point with automatically there is position deviation, can be further ensured that puncture needle needle point after exiting indwelling needle cavity will not again from
Puncture needle protection set stretches out, it is ensured that puncture needle needle point can effectively be hidden in puncture needle protection set.The set of puncture needle protection simultaneously
The structure that the thin slice at top and the thin slice of bottom or bottom plug combine, can be prevented effectively between puncture needle needle point and blood back bore portion
Remained blood in the blood back cavity formed splashes out, avoids patient blood to medical personnel and the biography of surrounding further
Dye, and this utility model simple in construction, low cost, easy for operation, practical.
