The right part for playing the syringe needle is provided with pressure part, and the right part of syringe needle is extend into inner casing, and the side of the pressure part is provided with groove,
The side of the inside of the inner casing is provided with lock piece, and the pressure part is connected with pressing means, the side of the pressing means by needle tubing
Face is provided with double wedge, and the right part of the pressing means is connected with pressure rod, and the side of the pressure rod is fixedly connected with protective case；
The trivial stop member is evenly distributed on the madial wall of inner casing；
The left part of the inner casing is provided with alcohol tampon.
Operation principle and process of the present utility model：
When needing to use blood taking needle to be taken a blood sample, toward shell internal direction pressing protective case, pressurization is made by pressure rod
Part is moved to the left, and double wedge and groove are meshed, and drives pressure part to move to the left, due to raised barrier, spring can be made to exist
Enclosure is compressed, and when unclamping protective case, spring is released, because the elastic force of spring is acted on, the mistake moved right in syringe needle
In journey and rotated, pressure part is locked out part stop, is taken a blood sample, need not made after the completion of blood sampling so as to expose syringe needle
Used time, protective case is pressed again, spring is compressed again, when unclamp protective case when, due to the elastic force of spring act on syringe needle to
During moving right and rotated, pressure part is locked out part release, pressure part and pressing means are moved to right part together, then
Needle retractable enters enclosure, is contaminated in atmosphere so as to avoid syringe needle, nor can accidentally injure medical personnel, and
And switch valve can be closed after the completion of blood sampling, switch valve is opened again when take a blood sample next time, is being adopted so as to avoid patient
The pain repeatedly being had an acupuncture treatment during blood.
The beneficial effects of the utility model：
The utility model is simple in construction, easy to use, by retractor device syringe needle can be made to be stretched in shell, when
It can in atmosphere be contaminated, nor can accidentally injure so as to avoid syringe needle by needle retractable in shell when unused
Needle tubing can be switched to medical personnel, and by switch valve, switch valve can be closed, treated down after the completion of blood sampling
Switch valve is opened again when once taking a blood sample, so as to avoid the pain repeatedly being had an acupuncture treatment in blood collection procedure.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Refer to shown in Fig. 1, one kind blood transfusion chemical examination blood taking needle, including shell 1, the inside of the shell 1 is provided with flexible
Device 2, the inside of the retractor device 2 is interspersed with needle tubing 3, and the side of the needle tubing 3 is provided with needle guard 4, and needle guard 4 is used for and taken a blood sample
Device is connected, and the outer surface of the needle tubing 3 is socketed with protective case 5, and the side of the protective case 5 is interspersed with switch valve 6, switch valve
6 are used for controlling the switch of needle tubing 3；
The retractor device 2 includes syringe needle 201, and the outer surface of the syringe needle 201 is socketed with spring 202, the syringe needle 201
Side provided with projection 203, projection 203 is used for block spring 202, and the right part of the syringe needle 201 is provided with pressure part 204, syringe needle
201 side is fixedly connected with pressure part 204, and the right part of syringe needle 201 is connected with needle tubing 3 in pressure part 204, and syringe needle
201 right part is extend into inner casing 205, and the side of the pressure part 204 is provided with groove 206, the side of the inside of the inner casing 205
