Abstract
The utility model discloses a kind of novel infusion needle, including needle guard main body and syringe needle, the syringe needle of the novel infusion needle includes straight line syringe needle section and the arc syringe needle section being connected with straight line syringe needle section end, and the arc syringe needle section is needle tip away from one end of connection end.The straight line syringe needle section of the novel infusion needle and the junction of arc syringe needle section are provided with hangnail.The arc syringe needle section chord length direction of the novel infusion needle and the angle in straight line syringe needle segment length direction are 45 °.The needle tip of the novel infusion needle is blunt circle.Hangnail and angle of bend are increased on syringe needle so that perfusion is fixed more to stablize quick, blunt round needle point is more convenient for the operator to carry out inserting needle.The novel infusion needle that the utility model is provided, can simple and quick completion perfusion operation, the incidence of pulmonary circulation when dramatically reducing perfusion not only ensure that pouring quality but also saved time and perfusion liquid.The utility model is adapted to popularity and uses.
Description
Technical field
The utility model belongs to biological technical field, more particularly to a kind of novel infusion needle.
Background technology
Perfusion fixation is a kind of removing animal body-internal-circulation blood, and structure of biological macromolecule changes in reduction zooblast
A kind of infrastest method, is widely used in the scientific research of brain diseases.In rat cerebral tissue's perfusion fixation procedure is carried out,
Need to use catheter needle to be irrigated fixation, venous catheter needle is often used at present, it is long that this mode irrigates the set time, Yi Lang
Take perfusion liquid, while easily there is pulmonary circulation, perfusion fault rate is higher, it is therefore desirable to invent a kind of dedicated for irrigating fixation
Novel infusion needle.
Utility model content
The problem that the utility model is solved is to provide a kind of incidence of pulmonary circulation when reducing perfusion, reduction and irrigates fixed
The novel infusion needle of duration and the fixed consumption liquid measure of reduction perfusion, it is proposed that following scheme：
A kind of novel infusion needle, including needle guard main body and syringe needle, the syringe needle of the novel infusion needle include straight line syringe needle section
And be connected with straight line syringe needle section end and integrated molding arc syringe needle section, arc syringe needle section is away from connection end
One end is needle tip.
Further improvement of these options, the straight line syringe needle section of the novel infusion needle and the junction of arc syringe needle section
It is provided with hangnail.
Further improvement of these options, arc syringe needle section chord length direction and the straight line syringe needle section of the novel infusion needle
The angle of length direction is 45 °.
Further improvement of these options, the needle tip of the novel infusion needle is blunt round structure.
The beneficial effect that the utility model is obtained：
（1）The novel infusion needle that the utility model is provided, increased hangnail and angle of bend on syringe needle so that perfusion is fixed
More stablize quick.
（2）Using novel infusion needle, the incidence of pulmonary circulation in run-bake-needle fault, and obvious reduction perfusion is difficult and to heart group
The damage knitted.
（3）The utility model on the premise of ensureing to brain tissue fixed effect, can significantly reduce perfusion it is fixed when
Consumption liquid measure that is long and significantly reducing perfusion fixation.
（4）It is more convenient for the operator to carry out inserting needle into blunt round structure needle point designs of the present utility model.
Brief description of the drawings
Fig. 1 is a kind of structural representation of novel infusion needle described in the utility model.
Brief description of the drawings：Straight line syringe needle section -1；Arc syringe needle section -2；Hangnail -3.
Specific embodiment
For technological means, creation characteristic, reached purpose and effect for realizing the utility model are easy to understand, below
With reference to specific embodiment, the utility model is expanded on further.
A kind of novel infusion needle as shown in Figure 1, including needle guard main body and syringe needle, the syringe needle bag of the novel infusion needle
Include straight line syringe needle section 1 and with straight line syringe needle section end be connected and integrated molding arc syringe needle section 2, the arc syringe needle
Section 2 is needle tip away from one end of connection end.
In the present embodiment, the straight line syringe needle section 1 of the novel infusion needle and the junction of arc syringe needle section 2 are provided with down
Thorn 3.Design hangnail 3 points out operator's inserting needle to suitable length, it is to avoid the too short run-bake-needle fault of inserting needle or long injury of myocardium, improves filling
Note efficiency and quality.
In the present embodiment, the arc syringe needle 2 chord length directions of section of the novel infusion needle and straight line syringe needle 1 length direction of section
Angle be 45 °.Angle is set and causes that perfusion operation is more consolidated quickly.
In the present embodiment, the needle tip of the novel infusion needle is blunt round structure.By needle point designs into blunt round knot
Structure is more convenient for the operator to carry out inserting needle.
The utility model provide perfusion fix pin, can simple and quick completion perfusion operation, dramatically reduce filling
The incidence of pulmonary circulation during note, not only ensure that pouring quality but also had saved time and perfusion liquid.
Those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to illustrate that this practicality is new
Type, and be not used as be to restriction of the present utility model, if in spirit of the present utility model, to the above
Change, the modification of embodiment will all fall in right of the present utility model.
