Abstract
A blood collection needle comprises a blood drawing syringe needle communicated with a blood injection syringe needle through a hose. One side of the blood drawing syringe needle and one side of the blood injection syringe needle are both provided with an adjustable needle base. Each adjustable needle base comprises a shell, wherein a screw, close to the side wall, in the shell is in screwed connection with a clamping head, the lower end of the clamping head is fixedly connected with a communication pipe, multiple seams are vertically drawn on the side wall of the communication pipe in the circumferential direction, the end, away from the clamping head, of the screw is fixedly connected with a rotary wheel outside the shell, and the end, away from the rotary wheel, outside the shell is provided with an end cap. By arranging the adjustable needle bases, the blood collection needle can completely eliminate the situation that the top end of a blood drawing syringe needle and the tip end of the blood injection syringe needle probably hurts people or animal and cause bacterium infection, and safety is improved.
Description
Technical field
The present invention relates to medical blood test field, particularly a kind of blood taking needle.
Background technology
In blood test, blood taking needle is a kind of very common medicine equipment, is mainly used in blood collection.General blood drawing is all coordinated using blood taking needle and negative pressure test tube.Blood taking needle is expendable consumed product, and after losing, the syringe needle of blood taking needle is all an exposure in air.This is not only easy to stab operator, it is also possible to accidentally injure other people；Especially after taking a blood sample to patients with infectious diseases, disease carrying germ will likely be carried on the syringe needle of blood taking needle, once stabbing human or animal, will result in the propagation of disease carrying germ, so that bringing the consequence for being difficult to expect to society.Even if there is the needle stand for preventing syringe needle from hurting sb.'s feelings infection in addition, because pin hole is too little, the risk being wounded by stabbing is equally existed during insertion.
The content of the invention
The technical problem to be solved is to provide a kind of blood taking needle, and the tip of blood drawing syringe needle and the tip of note blood syringe needle can be avoided to stab the situation that human or animal causes the propagation of disease carrying germ, improves security.
To solve above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of blood taking needle, including blood drawing syringe needle, blood drawing syringe needle is connected by flexible pipe with note blood syringe needle, the blood drawing syringe needle and note blood syringe needle side are equipped with adjustable needle stand, and can adjust needle stand includes shell, and inside the shell is connected by the screw rod of proximal wall with dop spiral, dop lower end is fixedly connected with siphunculus, a plurality of seam is along the circumferential direction vertically decorated with the wall of siphunculus side, the one end on screw rod away from dop is fixedly connected with the rotating wheel outside shell, the outer one end away from rotating wheel of shell is provided with end cap.
Described siphunculus material is elastomeric material.
Elastic ring is additionally provided with described flexible pipe.
A kind of blood taking needle of the present invention, by arranging adjustable needle stand, on the one hand blood taking needle syringe needle can be isolated, it is telescopic additionally, due to the siphunculus of adjustable needle stand, opening adjustable size, therefore staff will not be damaged in syringe needle insertion process, can thoroughly prevents syringe needle and stab the situation that human or animal causes the propagation of disease carrying germ, improve security.And the apparatus structure is simple, it is easy to implement.
Description of the drawings
With reference to the accompanying drawings and examples the invention will be further described：
Fig. 1 is the overall structure diagram of the present invention.
Fig. 2 is the schematic diagram that needle stand is can adjust in the present invention.
In figure：Blood drawing syringe needle 1, note blood syringe needle 2, flexible pipe 3 can adjust needle stand 4, shell 5, screw rod
6, dop 7, siphunculus 8, rotating wheel
9, seam 10, end cap 11, elasticity
12。
Specific embodiment
As shown in Figure 1 and 2, a kind of blood taking needle, including blood drawing syringe needle 1, blood drawing syringe needle 1 is connected by flexible pipe 3 with note blood syringe needle 2, the blood drawing syringe needle 1 and the side of note blood syringe needle 2 are equipped with adjustable needle stand 4, and can adjust needle stand 4 includes that the screw rod 6 in shell 5, shell 5 by proximal wall is connected with the spiral of dop 7, the lower end of dop 7 is fixedly connected with siphunculus 8, and the described material of siphunculus 8 is elastomeric material.Such as rubber, elastoplast.A plurality of seam 10 is along the circumferential direction vertically decorated with the side wall of siphunculus 8, the one end on screw rod 6 away from dop 7 is fixedly connected with the rotating wheel 9 outside shell 5, the outer one end away from rotating wheel 9 of shell 5 is provided with end cap 11.
As shown in figure 1, being additionally provided with elastic ring 12 on described flexible pipe 3.Thus structure, prevents pin from deviating from from needle stand, improves security.
When needing to process blood taking needle, turn rotating wheel 9, the dop 7 being connected with the spiral of screw rod 6 is moved downward with siphunculus 8, and is screwed out, because siphunculus 8 is provided with seam 10, the siphunculus opening for stretching out shell 5 opens, at this moment, the tip at the tip of blood drawing syringe needle 1 and note blood syringe needle 2 can be respectively placed in the needle stand 4 of other side, then opposite direction turn rotating wheel 9, siphunculus 8 is withdrawn, and covers end cap 11.Finally it is positioned in elastic ring 12 and tightens, thoroughly removes a hidden danger.
