Abstract
The utility model discloses a kind of remaining needle needle point protector, comprise Injector Bushing (3), sealing gasket (4), draw point (2) and blood back hole (1), protective sleeve of syringe needle (5) is provided with in described Injector Bushing (3), described protective sleeve of syringe needle (5) is positioned between described sealing gasket (4) and described handle (7), described protective sleeve of syringe needle (5) interior both sides are equipped with a slice locking plate (6), described draw point (2) is through in described protective sleeve of syringe needle (5), when described draw point (2) is extracted out, described locking plate (6) can enter double as lock buckling groove described blood back hole (1) in described draw point (2) is blocked in described protective sleeve of syringe needle (5).This utility model a kind ofly can avoid the remaining needle needle point protector of pricking wound by available protecting needle point when puncturing and extracting draw point successfully.
Description
Technical field
This utility model relates to a kind of needle point protector, particularly relates to a kind of remaining needle needle point protector.
Background technology
At present, the structure of remaining needle is provided with draw point and sealing gasket in Injector Bushing, and the needle point of draw point is provided with blood back hole, and rear end is provided with handle.When using retained needle puncture, after draw point is extracted, the needle point due to the draw point of remaining needle does not have protective sleeve to protect, and there is the shortcoming of stabbing medical personnel and transmission of disease.
Utility model content
Technical problem to be solved in the utility model is to provide a kind ofly can avoid the remaining needle needle point protector of pricking wound by available protecting needle point when puncturing and extracting draw point successfully.
In order to solve the problems of the technologies described above, the remaining needle needle point protector that this utility model provides, comprise Injector Bushing, sealing gasket, draw point and blood back hole, protective sleeve of syringe needle is provided with in described Injector Bushing, described protective sleeve of syringe needle is between described sealing gasket and described handle, in described protective sleeve of syringe needle, both sides are equipped with a slice locking plate, described draw point is through in described protective sleeve of syringe needle, when described draw point is extracted out, described locking plate can enter double as lock buckling groove described blood back hole in described draw point is blocked in described protective sleeve of syringe needle.
Adopt the remaining needle needle point protector of technique scheme, during for using retained needle puncture, after draw point is extracted, protection draw point needle point is in protective sleeve of syringe needle automatically, thus avoids stabbing medical personnel and transmission of disease.During use, extract draw point puncturing successfully, when the syringe needle of draw point retreats in protective sleeve of syringe needle, namely locking plate snaps in the blood back hole (lock buckling groove) at needle point position, and protective sleeve of syringe needle together exits together with draw point and inserts in sharp instrument recycling box afterwards.This utility model does not change the operational approach of former retained needle puncture, and do not do obvious adjustment to the profile of original needle body, after draw point exits, available protecting needle point is in protective sleeve, to reach the object that protection needle point avoids pricking wound.
In sum, this utility model a kind ofly can avoid the remaining needle needle point protector of pricking wound by available protecting needle point when puncturing and extracting draw point successfully.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, Fig. 2, Fig. 3, Figure 4 and 5; sealing gasket 4 and draw point 2 is provided with in Injector Bushing 3; the front end of draw point 2 is provided with blood back hole 1; rear end is provided with handle 7, is provided with protective sleeve of syringe needle 5 in Injector Bushing 3, and protective sleeve of syringe needle 5 is between sealing gasket 4 and handle 7; in protective sleeve of syringe needle 5, both sides are equipped with a slice locking plate 6; draw point 2 is through in protective sleeve of syringe needle 5, when draw point 2 is extracted out, locking plate 6 can enter double as lock buckling groove blood back hole 1 in draw point 2 is blocked in protective sleeve of syringe needle 5.
See Fig. 1, Fig. 2, Fig. 3, Figure 4 and 5; adopt the remaining needle needle point protector of technique scheme, during for using retained needle puncture, after draw point 2 is extracted; automatic protection draw point 2 needle point in protective sleeve of syringe needle 5, thus is avoided stabbing medical personnel and transmission of disease.During use; extract draw point 2 puncturing successfully; when the syringe needle of draw point 2 retreats in protective sleeve of syringe needle 5, namely locking plate 6 snaps in the blood back hole 1 (lock buckling groove) at needle point position, and protective sleeve of syringe needle 5 together exits together with draw point 2 and inserts in sharp instrument recycling box afterwards.
Claims (1)
1. a remaining needle needle point protector, comprise Injector Bushing (3), sealing gasket (4), draw point (2) and blood back hole (1), it is characterized in that: in described Injector Bushing (3), be provided with protective sleeve of syringe needle (5), described protective sleeve of syringe needle (5) is positioned between described sealing gasket (4) and handle (7), described protective sleeve of syringe needle (5) interior both sides are equipped with a slice locking plate (6), described draw point (2) is through in described protective sleeve of syringe needle (5), when described draw point (2) is extracted out, described locking plate (6) can enter double as lock buckling groove described blood back hole (1) in described draw point (2) is blocked in described protective sleeve of syringe needle (5).
