Description
Technical field
The utility model relates to a kind of medical instrument more particularly to a kind of blood taking needles.
Background technique
Existing blood taking needle 10 as shown in Figure 1, comprising: needle stand 11, the first end of needle stand 11 are formed with puncture needle 13,
The second end of needle stand 11 is formed with external thread part 12, and the second end of external thread part 12 is formed with the heparin tube steel surrounded by rubber cap
Needle 14；Puncture needle 13 is connected to heparin tube steel needle；The front end internal thread hole of blood taking needle 10 and needle holder passes through external thread part 12
It is combined together, after vacuum blood collection tube is inserted into needle holder 20；When blood sampling, puncture needle 13 is pierced into the vein blood vessel of patient, is adopted
Blood vessel steel needle penetrates rubber cap and the capping of vacuum blood collection tube enters in vacuum blood collection tube, thus blood via puncture needle 13,
Vacuum blood collection tube is flowed into after heparin tube steel needle.
Due to often needing to adopt patient multitube blood, at this moment, puncture needle 11 is always maintained in the blood vessels, and needle is held in replacement
Vacuum blood collection tube in device.When being replaced, puncture needle is inevitably movable, the needle point of puncture needle be easy to from
Intravascular puncture vascular wall and be located at extravascular, thus need to re-start puncture.
Utility model content
In view of the above problems, the utility model is directed to a kind of blood taking needle, can effectively avoid needle point in blood collection procedure
Extravascular happen is punctured to from intravascular.
The blood taking needle of the utility model comprising needle stand, needle stand are formed with set made of silica gel in the lower end of its first side
Pipe, needle stand are formed with the external screw thread of the internal thread hole of the center for being bound to needle holder front end in the upper end of its second side
Portion, external thread part are formed with the heparin tube steel needle surrounded by rubber cap, lower end end shape of the needle stand in its second side in its second end
At there is handle groove；It include slanted channel in needle stand, which is connected to casing with heparin tube steel needle；The lower end of slanted channel
It is separated with handle groove by the spaced walls of rubber；Puncture needle is accommodated in casing, the first end of puncture needle passes through spaced walls, warp
By in the lower end sleeve pipe of slanted channel, the tip of puncture needle is exposed to outside the first end of casing；When blood taking needle with hold
When needle device combines, the second end of puncture needle is located at the lower section of the front end of needle holder, and puncture needle is freely pulled out
Out.
Preferably, the second end of puncture needle is formed with handle, and the first end of handle is located in handle groove, and the second of handle
End is located at outside handle groove.
Preferably, puncture needle is solid needle.
By the blood taking needle of the utility model, it is puncture and indwelling by the Function Decomposition of puncture needle, punctures by steel needle
It completes, indwelling has the casing of silica gel to complete；Puncture needle is transferred to after completing to puncture, only retains silica gel sleeve pipe in patient vessel
It is interior, even if the casing activity when changing heparin tube, will not pierce through blood vessel from inside to outside.

Specific embodiment
In the following, being described in detail in conjunction with blood taking needle of the attached drawing to the utility model.
The utility model uses for reference the structure of indwelling, is transformed to blood taking needle.
The blood taking needle 10 of the utility model comprising needle stand 11, needle stand 11 are formed with silica gel system in the lower end of its first side
At casing 15, needle stand 11 is formed with the interior spiral shell of the center for being bound to 20 front end of needle holder in the upper end of its second side
The external thread part 12 of pit, external thread part 12 are formed with the heparin tube steel needle 14 surrounded by rubber cap, needle stand 11 in its second end
Handle groove 17 is formed at the lower end end of its second side；It include slanted channel 19 in needle stand 11, the slanted channel 19 is by casing 15
It is connected to heparin tube steel needle 14；The lower end of slanted channel 19 is separated with handle groove 17 by the spaced walls 18 of rubber；Hold in casing 15
Receiving has puncture needle 13, and the first end of puncture needle 13 passes through spaced walls 18, via the lower end sleeve pipe 15 of slanted channel 19
In, the tip of puncture needle 13 is exposed to outside the first end of casing 15；When blood taking needle 10 is combined with needle holder 20, steel is punctured
The second end of needle 13 is located at the lower section of the front end of needle holder 20, as shown in figure 4, pulling out puncture needle 13 freely
Out.The second end of puncture needle 13 is formed with handle 16, and the first end of handle 16 is located in handle groove 17, the second end of handle 16
Outside handle groove 17.Puncture needle 13 be solid needle, the puncture needle for the blood taking needle being different from the prior art, the prior art
The puncture needle of blood taking needle is hollow.
In use, then puncture needle is punctured together with casing into patient's first by blood taking needle in conjunction with needle holder
In vein blood vessel, steel needle is extracted, vacuum blood collection tube is fitted into needle holder and is covered on heparin tube steel needle, can be carried out in this way
Blood sampling.When needing to change heparin tube, the heparin tube for adopting full blood sample is pulled up, changes new heparin tube.It is endovascular due to being retained in
It is the casing of silica gel, even if heparin tube is movable in the blood vessels during changing heparin tube, the tip of casing will not be from inside to outside
Pierce through blood vessel.Further, since trochar and puncture needle are located at the lower end of needle holder, compare when being punctured and the prior art
Puncture needle be located at the center of needle holder, the angle of puncture can be smaller.
