Abstract
The utility model discloses an examination and blood sampling needle, and belongs to the technical field of medical instruments. The examination and blood sampling needle consists of a needle cylinder (1), a needle cylinder cap (2), a needle (3), a piston (4) and a pintle (5). The examination and blood sampling needle is characterized in that: the needle cylinder cap (2) provided with the needle (3) is hermetically sleeved at the front end of the needle cylinder (1) of which the rear outer wall is provided with an annular protrusion (6), the side wall of the piston (4) in the needle cylinder (1) is provided with a limiting convex rib (8) adapting to an axial groove (7) in the inner wall of the needle cylinder (1), the pintle (5) penetrates through the bottom of the needle cylinder (1) and a through hole adapting to the pintle (5) and then is in threaded connection to a threaded tube (9) fixed in a groove in the center of the bottom of the piston (4). The examination and blood sampling needle is easy and convenient to operate, time-saving and labor-saving during examination and blood sampling, and can prevent a blood sample from being damaged and lighten the working difficulty of medical staff.
Description
Technical field
This utility model belongs to the medical instruments technical field, is a kind of check blood taking needle specifically.
Background technology
At present, when testing blood sampling to patient, use the syringe pump blood sample mostly, and then inject BIAO and BEN in vitro clinically, operation very bothers like this, wastes time and energy, and damages sample easily, has increased medical worker's work difficulty.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of easy and simple to handle, time saving and energy saving when testing blood sampling to patient, and can avoid the check blood taking needle of sample damage.
The technical scheme of this utility model is: this check blood taking needle is made up of syringe, syringe medicated cap, syringe needle, piston, pintle; Above, the syringe forward end seal suit that the rear end outer wall is provided with annular protrusion is provided with the syringe medicated cap of syringe needle; Syringe internal piston sidewall is provided with the retaining convex rib that adapts with syringe inwall axial notch, and pintle passes the through hole rear thread that syringe bottom adapts with it and is connected in the corrugated tubing of piston bottom center groove internal fixation.
After blood sampling finishes, move the piston in the syringe to syringe bottom after, the rotation pintle can be laid down pintle from piston, and then the syringe medicated cap of syringe upper end is laid down and can blood sample be inspected by ready samples.
The beneficial effect of this utility model is: easy and simple to handle, time saving and energy saving when testing blood sampling to patient, and can avoid blood sample to be damaged, alleviated medical worker's work difficulty.
