Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly to a kind of blood taking needle.
Background technology
For transfusion or the blood taking needle of blood drawing in prior art, its syringe needle is both provided with needle guard, when infusing or draw blood, protects
Syringe needle is pulled out by scholar, can carry out puncture of infusing or draw blood.But after transfusion or blood drawing terminate, due on the needle guard that pulls out
Pin hole is the least, and therefore to be again worn on syringe needle by needle guard, difficulty is relatively big, easily stabs finger；And do not put to blood taking needle
Needle guard, blood taking needle is exposed outside, when reclaiming blood taking needle, there is also and stabs nurse's risk.
Many studies have shown that, nurse is the professional colony that in hospital, pricking wound occurrence frequency is the highest, and nurse is also sense simultaneously
The colony occurred frequently of dye Emperical Bayesian method.More than 20 kind hematogenous infectious disease, the most most common, danger can be propagated by pricking wound
That evil is maximum is HBV, HCV, HIV.
The most how preventing blood taking needle from stabbing medical personnel is letter major issue to be solved.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of telescopic Anti-stabbing blood taking needle, to solve prior art
In blood taking needle easily stab the technical problem of medical personnel.
This utility model telescopic Anti-stabbing blood taking needle, including the needle handle of syringe needle, flexible pipe, connecting needle and flexible pipe, also wraps
Including protecting pipe, described protecting pipe is provided with along its axially extended straight gathering sill, described needle handle is by cylindrical section and is arranged at circle
The annular flange flange composition of shell of column rear end, described annular flange flange is provided with the guiding projection being slidably matched with straight gathering sill；Described
The endoporus of protecting pipe is by the front pilot hole section being slidably matched with cylindrical end and the rear pilot hole section group being slidably matched with annular flange flange
Become, described needle handle is cased with end and withstands on the compression spring on annular flange flange end face；
The external cylindrical surface of described protecting pipe is threaded thread bush, described thread bush is provided with and dodges guiding projection
Axial groove；
It is additionally provided with handle on the front end external cylindrical surface of described protecting pipe.
Further, described telescopic Anti-stabbing blood taking needle, also include the needle guard coordinated with syringe needle.
The beneficial effects of the utility model:
This utility model telescopic Anti-stabbing blood taking needle, its syringe needle, when blood drawing or transfusion, is being guided by thread bush gear
On projection side, making syringe needle be positioned at outside protecting pipe, blood drawing or vein puncture are not affected by protecting pipe；Terminate in blood drawing or transfusion
Time, rotate thread bush, make the axial groove on thread bush just to guiding projection, at this moment syringe needle and needle handle are made in the thrust of compression spring
Move axially along protecting pipe with lower, in syringe needle the most automatic retraction protecting pipe, thus medical personnel can be protected from needle sting, adopt
Blood pin is safe to use.
Accompanying drawing explanation
Fig. 1 is that the syringe needle of the present embodiment telescopic Anti-stabbing blood taking needle stretches out the structural representation under protecting pipe state；
Fig. 2 is the structural representation under the syringe needle retraction protecting pipe state of the present embodiment telescopic Anti-stabbing blood taking needle；
Fig. 3 is protecting pipe and the plan structure schematic diagram of thread bush combination；
Fig. 4 is the main TV structure schematic diagram of thread bush.
Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
As it can be seen, the present embodiment telescopic Anti-stabbing blood taking needle, including syringe needle 1, flexible pipe 2, connecting needle and flexible pipe
Needle handle 3, also includes protecting pipe 4, described protecting pipe is provided with along its axially extended straight gathering sill 5, and described needle handle 3 is by cylinder
Section 31 and the annular flange flange 32 being arranged at cylindrical section rear end form, and described annular flange flange is provided with and is slidably matched with straight gathering sill
Guiding projection 6；The endoporus of described protecting pipe is joined by the front pilot hole section being slidably matched with cylindrical end with annular flange flange slip
The rear pilot hole section group closed
Become, described needle handle is cased with the compression spring 7 that end withstands on annular flange flange end face；
The external cylindrical surface of described protecting pipe is threaded thread bush 8, described thread bush is provided with and dodges guiding projection
Axial groove 9；
It is additionally provided with handle 10 on the front end external cylindrical surface of described protecting pipe.
The present embodiment telescopic Anti-stabbing blood taking needle, its syringe needle is when blood drawing or transfusion, convex in guiding by thread bush gear
On block side, making syringe needle be positioned at outside protecting pipe, blood drawing or vein puncture are not affected by protecting pipe；At the end of blood drawing or transfusion,
Rotating thread bush, make the axial groove on thread bush just to guiding projection, at this moment syringe needle and needle handle are in the thrust of compression spring
Lower move axially along protecting pipe, in syringe needle the most automatic retraction protecting pipe, thus medical personnel can be protected from needle sting, blood sampling
Pin is safe to use.
The present embodiment telescopic Anti-stabbing blood taking needle, also includes the needle guard 11 coordinated with syringe needle, at original state, syringe needle 1
It is in outside protecting pipe, by arranging needle guard 11, syringe needle can be prevented to be contaminated, also can prevent from stabbing when taking blood taking needle.
Finally illustrating, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although ginseng
According to preferred embodiment, this utility model is described in detail, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent, without deviating from objective and the model of technical solutions of the utility model
Enclosing, it all should be contained in the middle of right of the present utility model.
