Fig. 1-3 is please referred to, the utility model provides a kind of technical solution:
Quick arteriovenous identifies remaining needle, as shown in Figure 1, including tube socket 1, the side of tube socket 1 is equipped with lever 11, tube socket 1
One end be connected with fixing pipe 12, fixing pipe 12 is equipped with needle tubing 13 far from one end level of tube socket 1, and needle tubing 13 passes through fixing pipe
12 are connected with the inside of tube socket 1, and tube socket 1 is equipped with connecting tube 14 far from the side of lever 11, and connecting tube 14 and tube socket 1 is interior
Portion is connected, and connecting tube 14 is connected with drainage tube 15 far from one end of tube socket 1, and drainage tube 15 is connected far from one end of connecting tube 14
There is tee tube 16, is also arranged with tongs 17 on drainage tube 15.
Specifically, tube socket 1, lever 11 and fixing pipe 12 are all made of PVC material and are made, there is steady chemical structure, and
And the advantage that material is hard, increase the service life used.
As shown in Figure 1, Figure 2 and Figure 3, tube socket 1 is connected with identification pipe 2 far from one end of fixing pipe 12, identifies in pipe 2
Centre position is equipped with demarcation plate 21 vertically, and the periphery ring of demarcation plate 21 and the inner wall of identification pipe 2 are tightly connected, the center of demarcation plate 21
Net position offers circular hole 211, and demarcation plate 21 is equipped with pigment bin 22 close to the side of tube socket 1, and the side of pigment bin 22 is connected with
Sprue 221, demarcation plate 21 are equipped with water storing bin 27 far from the side of pigment bin 22, and pigment bin 22 is set far from the side of demarcation plate 21
There is fixed plate 23, fixed plate 23 is equipped with slide plate 24 far from the side of pigment bin 22, and the outer wall of drive rod 25 is also arranged with spring 26,
And spring 26, between fixed plate 23 and slide plate 24, slide plate 24 has biography close to the side central location horizontal connection of fixed plate 23
Lever 25, and drive rod 25 passes through fixed plate 23, drive rod 25 is connected with sealing-plug 251 far from one end of slide plate 24, by setting
The pigment bin 22 and water storing bin 27 set, when being inserted into artery, since the pressure of arterial blood is larger, and the pressure of venous blood
Very little is able to drive slide plate 24 to the movement of the side of fixed plate 23 by the pressure of arterial blood at this time, can make sealing-plug at this time
251 are separated from each other with circular hole 211, and the pigment in pigment bin 22 is mutually merged with the water phase in water storing bin 27, and medical staff only needs
The colour switching of water storing bin 27 is observed, just can quickly identify remaining needle insertion is artery or vein, is not only increased
The speed of judgement, and it is also more accurate.
Specifically, slide plate 24 and the inner wall of identification pipe 2 are slidably connected, and slide plate 24 is made of polytetrafluoroethylene (PTFE), is had
Preferable self-lubricating effect can increase the fluency of sliding in the pressure by arterial blood, and then ensure that the steady of work
It is qualitative.
Further, sealing-plug 251 is in a circular table shape, and sealing-plug 251 and circular hole 211 are mating, in the band of spring 26
Under dynamic, facilitate the grafting of sealing-plug 251 and circular hole 211 and be sealed.
Further, identification pipe 2 is made of polyvinyl chloride, is had the advantages that material is transparent, nontoxic, is facilitated doctor

It also can be more smooth when sliding.
The quick arteriovenous of the present embodiment identifies remaining needle when in use, through sprue 211 into pigment bin 22
Medical pigment is injected, then is clamped drainage tube 15 by tongs 17, is at this time inserted into needle tubing 13 in the blood vessel of patient, when slotting
When what is entered is artery, since the pressure of arterial blood is larger, blood can push slide plate 24 to fixation under the effect of the pressure
The side of plate 23 is mobile, and fixed plate 23 will drive the movement of drive rod 25, and then can make between sealing-plug 251 and circular hole 211
It is separated from each other, is interconnected between pigment bin 22 and water storing bin 27 by circular hole 211 at this time, the pigment in pigment bin 22 can be with storage
Water in sump 27, which contacts with each other, makes aquatic products change color, and the color that then medical staff can pass through water in observation water storing bin 27 becomes
Change can quickly identify arteriovenous；When being inserted into vein, since the pressure of venous blood is preferable, and then in the work of spring 26
It not will push 24 one end of slide plate under, will not be connected between pigment bin 22 and water storing bin 27 at this time, and then water will not generate change
Color.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
