Description
Technical field
The utility model is related to medical instruments field, especially a kind of safety type blood-taking needle.
Background technology
After acquiring blood using blood taking needle, heparin tube is removed, heparin tube is sent into inspection.After the completion of blood sampling, syringe needle is easy
Accidentally injure nurse.Meanwhile heparin tube connect tighter with connector, and syringe outer wall is relatively smooth, it is difficult to brisk using smaller strength
Ground existing syringe is taken out heparin tube.
Invention content
The utility model is directed to deficiencies of the prior art, provides a kind of blood taking needle simple in structure, syringe with
Bloodletting tube is connected through a screw thread, and needle cap is set convenient for bloodletting tube with the connection of syringe with detaching, outside syringe needle, can rotate exposing or
Syringe needle is hidden, ensures the safety of blood taking needle, the outer wall of syringe is equipped with rubber segments, increases the frictional force between hand and syringe, just
Syringe is held in pinching.
The purpose of this utility model is to be achieved through the following technical solutions：
A kind of safety type blood-taking needle, including syringe, bloodletting tube, connector, connecting tube, syringe needle, the inner wall of the syringe is set
Be equipped with internal thread, the bloodletting tube is connected through a screw thread with syringe, sets needle cap outside the syringe needle, the syringe needle outer wall with
Needle cap inner wall is connected by thread helix.
Further, the syringe needle outer wall is provided with nested screw thread with needle cap inner wall.
Further, the outer wall of the syringe is equipped with rubber segments.
Further, the length of the rubber segments is the 1/3 of syringe length.
Further, the rubber segments are set on the middle part of syringe outer wall axial direction.
Further, the rubber segments are equipped with lines.
Further, the connector is fixed on one end end of syringe.
Utility model advantageous effect：Have the advantages that simple in structure, syringe is connected through a screw thread with bloodletting tube, convenient for blood drawing
Pipe sets needle cap with the connection of syringe with detaching outside syringe needle, can rotate exposing or hiding syringe needle, ensures the safety of blood taking needle
Property, the outer wall of syringe increases the frictional force between hand and syringe, syringe is held convenient for pinching equipped with rubber segments.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
1st, syringe；2nd, bloodletting tube；3rd, connector；4th, connecting tube；5th, syringe needle；6th, internal thread；7th, needle cap.
Specific embodiment
It is noted that following detailed description is all illustrative, it is intended to provide further instruction to the application.It is unless another
It indicates, all technical and scientific terms used herein has usual with the application person of an ordinary skill in the technical field
The identical meanings of understanding.The utility model is described in further detail below according to drawings and examples：
As shown in Figure 1, the utility model safety type blood-taking needle includes syringe 1, bloodletting tube 2, connector 3, connecting tube 4, syringe needle
5, the inner wall of the syringe 1 is provided with internal thread 6, and the bloodletting tube 2 is connected through a screw thread with syringe 1, outside the syringe needle 5
Needle cap 7 is set, and 5 outer wall of syringe needle is connect by thread helix in 5 outer wall of syringe needle and needle cap 7 with 7 inner wall of needle cap
Wall is provided with nested screw thread.
The outer wall of the syringe 1 is equipped with rubber segments, and rotate syringe 1 convenient for medical staff is detached from bloodletting tube 2.
The length of the rubber segments is the 1/3 of 1 length of syringe.
The rubber segments are set on the middle part of syringe 1 outer wall axial direction.
Increase the frictional force between hand and syringe 1, syringe 1 is held convenient for pinching, the rubber segments are equipped with lines.
The connector 3 is fixed on one end end of syringe 1.
Operation principle：5 outside needle cap 7 of medical staff's rotating needle has an acupuncture treatment after exposing syringe needle 5, rotates clockwise needle thereafter
Cylinder 1, syringe 1 and 2 bonding in vacuum of bloodletting tube start to take a blood sample.After blood taking needle acquisition blood, medical staff takes needle from patient
Needle cap 7 is rotated afterwards, and syringe needle 5, which is rotated into needle cap 7, to be prevented from stabbing medical staff.Bloodletting tube 2 connect relatively tight, medical care with connector 3
Personnel, which only need to rotate syringe 1 counterclockwise, removes bloodletting tube 2, and bloodletting tube is sent to inspection.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation, although the utility model has been disclosed with preferred embodiment as above, be not limited to the present invention, it is any to be familiar with sheet
