The purpose of this utility model can reach by the following technical solutions:
A kind of safe type retention needle, comprise casing seat, be socketed on the sleeve pipe of casing seat front end, needle tubing, the needle stand that is connected with needle tubing end, the front end of described needle tubing is slidably stretched out so state sleeve pipe through described casing seat and sleeve pipe successively, it is characterized in that: also include safety clamp, described safety clamp is located in casing seat, and be socketed on described needle tubing, when needle tubing exits casing seat, cover the needle point of needle tubing.
Further, described safety clamp is can the clamp structure of folding, innerly forms accommodating cavity, and needle tubing is held on needle tubing along the front end of safety clamp described during cannula slide; When the needle point of described needle tubing slides to accommodating cavity inside, the front end of described safety clamp covers the needle point of needle tubing.
Further, described safety clamp is provided with the first outwardly projection, accordingly, described internal surface of sleeve pipe is provided with the second projection internally protruded, and the front end of described safety clamp flicks and to be held on needle tubing thus to be arranged on casing seat inside by the first projection clamping second projection.
Further, the rear end of described safety clamp has through hole, and accordingly, described needle tubing is provided with the 3rd outwardly projection, and the described 3rd needle point protruding through top pressure through hole restriction needle tubing deviates from accommodating cavity by through hole.
Further, the needle point of needle tubing is less than the length of accommodating cavity to the distance of the 3rd projection.
As the preferred scheme of one, described sleeve pipe is fixedly connected on described casing seat by rivet.
As the preferred scheme of one, the supporting joint be provided with for aerofluxus on described needle stand.
Implement this utility model, there is following beneficial effect:
This utility model arranges safety clamp on needle tubing, when needle tubing completes in the process puncturing and exit, needle tubing slides relative to safety clamp, the needle point sleeve of needle tubing is made to be located at safety clamp inside, and under the stop of the 3rd projection, needle point cannot exit safety clamp, thus thoroughly ensure that needle point covers completely and be combined in accommodating cavity to deviate from, ensure that the life security of medical personnel, there is security protection, easy to use and reliable beneficial effect.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Specific embodiment 1:
See figures.1.and.2, the present embodiment comprises casing seat 1, is socketed on the sleeve pipe 2 of casing seat 1 front end, needle tubing 3, the needle stand 4 that is connected with the end of needle tubing 3, the front end of described needle tubing 3 is slidably stretched out so state sleeve pipe 2 through described casing seat 1 and sleeve pipe 2 successively, it is characterized in that: also include safety clamp 5, described safety clamp 5 is located in casing seat 1, and be socketed on described needle tubing 3, when needle tubing 3 exits casing seat 1, cover the needle point of needle tubing 3.
The concrete structure at the tip of position needle tubing 3 is covered: as shown in Figures 2 and 3 as safety clamp 5, described safety clamp 5 is can the clamp structure of folding, the accommodating cavity 6 of inner formation, when carrying out venipuncture, when needle tubing 3 slides along sleeve pipe 2, the front end of described safety clamp 5 is held on needle tubing 3, and the needle point of needle tubing 3 stretches out sleeve pipe 2 carries out human vein puncture; After puncture completes and exits, the needle point of described needle tubing 3 slide to accommodating cavity 6 inner time described safety clamp 5 front end cover the needle point of needle tubing 3.And exit sleeve pipe 2 at needle tubing 3 and slide in the process of accommodating cavity 6, in order to fixing safety clamp 5, needle tubing 3 is slided relative to safety clamp 5, described safety clamp 5 is provided with the first outwardly projection 51, accordingly, described sleeve pipe 2 inwall is provided with the second projection internally protruded, and the front end of described safety clamp 5 flicks and to be held on needle tubing 3 thus to be arranged on casing seat 1 by the first projection 51 clamping second projection inner.
When the needle point of needle tubing 3 falls back on after in accommodating cavity 6, move back safety clamp 5 to prevent needle point, cause needle point outside exposed and stab medical personnel situation occur, the rear end of described safety clamp 5 has through hole, accordingly, described needle tubing 3 is provided with the 3rd outwardly projection 31, and described 3rd projection 31 deviates from accommodating cavity 6 by the needle point of top pressure through hole restriction needle tubing 3 by through hole.Described needle tubing 3 is slidably connected through through hole and safety clamp 5.Needle tubing 3 is arranged for the particular location of the 3rd projection 31, and the needle point of needle tubing 3 is less than the length of accommodating cavity 6 to the distance of the 3rd projection 31.
On the mounting structure of casing seat 1, described sleeve pipe 2 is fixedly connected on described casing seat 1 by rivet.The supporting joint 7 be provided with for aerofluxus on described needle stand 4.
Operation principle of the present utility model:
As shown in Figure 2, when carrying out venipuncture, the front end of safety clamp 5 is strutted by needle tubing 3 and is clamped on needle tubing 3, and because safety clamp 5 is softened, first projection of safety clamp 5 snaps fit onto in the second projection of casing seat 1, make safety clamp 5 be limited to be fixedly mounted in casing seat 1, needle tubing 3 can stretch out sleeve pipe 2 along sleeve pipe 2 forward slip and carry out puncturing operation.
After puncture completes, as shown in Figure 3, needle tubing 3 exits backward, and because safety clamp 5 is connected on casing seat 1, needle tubing 3 slides on safety clamp 5.When the needle point of needle tubing 3 slides in accommodating cavity 6, safety clamp 5 clamping, makes needle point be covered by the front end of safety clamp 5.And when needle tubing 3 slides into the position that the 3rd projection 31 contacts with through hole, due to the stop of the 3rd projection 31, needle tubing 3 cannot be extracted out in safety clamp 5, thus thoroughly ensure that needle point covers completely and be combined in accommodating cavity 6, ensure that the life security of medical personnel.After safety clamp 5 clamping, the first projection 51 is deviate from from the second projection, and under the effect of the 3rd projection 31, safety clamp 5, by needle tubing 3 pull-out in casing seat 1, realizes safety clamp 5 and disassembles rapidly from casing seat, flexible structure, easy to use.
Above disclosedly be only a kind of preferred embodiment of this utility model, certainly can not limit the interest field of this utility model with this, therefore according to the equivalent variations that this utility model claim is done, still belong to the scope that this utility model is contained.
