Description
Technical field
This utility model belongs to medical test apparatus technical field, is specifically related to a kind of medical test blood taking needle.
Background technology
The method of blood is gathered in current medical test, generally that direct blood taking needle extracts blood, to extract blood transfer after blood in vitro, then chemically examine, because the syringe needle of blood taking needle itself has length, therefore when extruding blood taking needle piston rod, blood can not be extruded blood taking needle completely, therefore when piston rod is expressed to the end of blood taking needle, need syringe needle and blood taking needle body to separate, the remained blood in syringe needle is discharged.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of structure simple, be convenient to installing/dismounting, row's blood medical test blood taking needle thorough, easy to use.
The purpose of this utility model is achieved in that a kind of medical test blood taking needle, it comprises cylindrical shell, the arranged outside of described cylindrical shell has uniform scale, the inside of described cylindrical shell is provided with the piston head of fitting with cylinder inboard wall, the outside of described piston head is connected with piston rod, the left side of described cylindrical shell is connected with connection, the right-hand member of described connection is provided with nipple, the outside of described nipple is evenly provided with screw thread, the left end of described connection is connected with syringe needle, and the inside of the right-hand member of described syringe needle is provided with skid resistant course.
The end of described cylindrical shell is provided with circular cylinder edge.
The length of described piston rod is greater than the length of cylindrical shell.
The structure of described connection is the structure that the thin right-hand member of left end is thick.
The structure of described nipple is cylindrical structure.
Described syringe needle and skid resistant course are integral type structure.
The beneficial effects of the utility model: be connected with connection by the left end at cylindrical shell, the left end connecting needle of connection, blood taking needle is designed to split-type structural, not only rational in infrastructure, and be convenient to installation and removal, when blood in transfer blood taking needle is in the process of test tube, when the piston rod in cylindrical shell is expressed to end, connection can be taken off, discharge the blood remained in connection, therefore decrease the blood flow volume extracting testee to a certain extent, avoid the waste of blood; Total this utility model have structure simple, be convenient to installing/dismounting, row's blood advantage thorough, easy to use.
Accompanying drawing explanation
