It is integrated for blood collecting containers and blood taking needle or is directly prepared into using liquaemin liquid moistening syringe.
Existing vacuum blood taking needle can dismantle syringe needle after actually used, then syringe needle is put into into specific collection box
It is interior, because syringe needle does not do protective treatment when reclaiming, therefore it is very easy to stab recovery personnel.
Utility model content
The purpose of this utility model is to provide a kind of vacuum blood taking needle, to solve above-mentioned background technology in propose ask
Topic.
For achieving the above object, the utility model provides following technical scheme：
A kind of vacuum blood taking needle, including outer tube, are provided with needle cavity in the outer tube, blood taking needle is provided with needle cavity, adopt
The end of blood pin is installed with limited block, and limited block is movably arranged in the limit chamber on the inside of outer tube, the blood taking needle
Bottom pass through limited block, and the bottom of blood taking needle to be connected with connector, connector is by connection flexible pipe and vacuum blood collection bottle phase
Connection, and described vacuum blood collection bottle is fixedly connected on the bottom of outer tube in the form of buckle；The limited block and outer tube
Slide block on outer wall is fixedly connected, and slide block is movably arranged in the chute in overcoat pipe outer wall, causes to adopt by promoting slide block
Move on blood pin, and limited block allows to avoid syringe needle from excessively stretching out with the setting of limit chamber；The head end of the outer tube is provided with
Spacing head, the center of spacing head is provided with the through hole being connected with needle cavity, can prevent from penetrating suddenly using spacing head it is too deep, and
And blood taking needle can be taken in using after terminating, the setting of spacing head can prevent recovery personnel from being stabbed by blood taking needle.
As further program of the utility model：Dust-proof release liners are coated with the surface of the through hole.
As the utility model further scheme：The surface of the vacuum blood collection bottle is provided with graduation mark.
Compared with prior art, the beneficial effects of the utility model are：The utility model simple structure, it is easy to use, it is whole
Body is safe, can avoid needlestick injuries other people, while using can realize after terminating syringe needle take in so that recovery personnel keep away
From wound.
Description of the drawings
Fig. 1 is a kind of structural representation of vacuum blood taking needle of the utility model.
In figure：The spacing head of 1- outer tubes, 2-, 3- through holes, 4- needle cavities, 5- blood taking needles, 6- limit chambers, 7- limited blocks, 8- are slided
Block, 9- vacuum blood collection bottles, 10- connection flexible pipes, 11- connectors, the dust-proof release liners of 12-.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1 is referred to, in the utility model embodiment, a kind of vacuum blood taking needle, including outer tube 1, in the outer tube 1
It is provided with needle cavity 4, needle cavity 4 and blood taking needle 5 is installed, the end of blood taking needle 5 is installed with limited block 7, and the activity peace of limited block 7
It is mounted in the limit chamber 6 of the inner side of outer tube 1, the bottom of the blood taking needle 5 passes through limited block 7, and the bottom of blood taking needle 5 to be connected with
Connector 11, connector 11 is connected by connection flexible pipe 10 with vacuum blood collection bottle 9, and described vacuum blood collection bottle 9 is with buckle
Form be fixedly connected on the bottom of outer tube 1；The limited block 7 is fixedly connected with the slide block 8 on the outer wall of outer tube 1, and sliding
Block 8 is movably arranged in the chute on the outer wall of outer tube 1, causes to be moved on blood taking needle 5 by promoting slide block 8, and limited block 7 and limit
The setting in position chamber 6 allows to avoid syringe needle from excessively stretching out；The head end of the outer tube 1 is provided with spacing 2, in spacing 2
The through hole 3 being connected with needle cavity 4 is provided with the heart, can prevent from penetrating suddenly using spacing 2 it is too deep, and using can after terminating
So that blood taking needle 5 to be taken in, the setting of spacing 2 can prevent recovery personnel from being stabbed by blood taking needle.
Dust-proof release liners 12 are coated with the surface of the through hole 3.
The surface of the vacuum blood collection bottle 9 is provided with graduation mark.
Operation principle of the present utility model is：Limited block 7 is fixedly connected with the slide block 8 on the outer wall of outer tube 1, and slide block 8
Be movably arranged in the chute on the outer wall of outer tube 1, by promote slide block 8 cause blood taking needle 5 on move, and limited block 7 with it is spacing
The setting in chamber 6 allows to avoid syringe needle from excessively stretching out, and by the way that blood taking needle 5 is released, blood sampling is so just capable of achieving, by blood taking needle
5 incomes, can realize safe recovery again.
