Abstract
A needle dismounting device belongs to the technical field of medical auxiliary instruments and comprises a sleeve (1), a finger ring (2), an elastic clamp arm (3) and a clamp plate (4). The needle dismounting device is characterized in that the finger ring (2) is fixedly connected to the outer wall of an open end of the sleeve (1), the inner diameter of the sleeve (1) is larger than the outer diameter of a needle seat and smaller than the outer diameter of a needle cylinder, the elastic clamp arm (3) is fixedly connected onto the outer wall of the sleeve (1) opposite to the finger ring (2), the clamp plate (4) clinging to the open end face of the sleeve (1) is fixedly connected to the front end of the elastic clamp arm (3), an inverted 'U'-shaped bayonet (5) is arranged at the lower end of the clamp plate (4), and the width of the inverted 'U'-shaped bayonet (5) is larger than the outer diameter of a syringe nipple and smaller than the outer diameter of the needle seat. The needle dismounting device is simple in structure and safe and convenient in use, needles can be easily dismounted, and working efficiency is improved.
Description
Technical field
This utility model belongs to the medical auxiliary apparatus technical field, specifically a kind of syringe needle puller.
Background technology
At present, clinical laboratory takes a blood sample with ordinary syringe when blood sampling mostly clinically, generally will blood collection needles be taken off after blood sampling finishes, and then the blood branch is annotated in the test tube.And do not have special-purpose syringe needle extracting tool now, and the reviewer directly takes off syringe needle with hands, and easy like this finger of stabbing the reviewer causes infection.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy and simple to handle, the syringe needle puller that can very easily syringe needle be disassembled.
The purpose of this utility model is achieved in that this syringe needle puller is made up of sleeve, finger ring, elasticity jig arm, clamp; Internal diameter connects less than the sleeve opening end outer wall of syringe external diameter greater than the needle holder external diameter is fixing finger ring; Be connected on the sleeve outer wall relative and fixing the elasticity jig arm with finger ring; Elasticity jig arm front end connects is fixing the clamp of being close to the uncovered end face of sleeve, and the clamp lower end is provided with width and falls " U " shape bayonet socket greater than the syringe nipple external diameter less than the needle holder external diameter.
During use, press the compression elasticity jig arm behind the syringe needle insertion sleeve with the syringe front end, the bayonet socket of clamp lower end promptly may be stuck on the nipple of needle holder rear end, spurs sleeve then, and syringe needle can disassemble and get in the sleeve.
The beneficial effect of this utility model is: simple in structure, safe in utilization, convenient, can very easily syringe needle be disassembled, and increase work efficiency.
Description of drawings
Accompanying drawing is the structure cutaway view of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this syringe needle puller is made up of sleeve 1, finger ring 2, elasticity jig arm 3, clamp 4; Internal diameter connects less than the sleeve 1 opening end outer wall of syringe external diameter greater than the needle holder external diameter is fixing finger ring 2; Be connected on sleeve 1 outer wall relative and fixing elasticity jig arm 3 with finger ring 2; Elasticity jig arm 3 front ends connect is fixing the clamp 4 of being close to sleeve 1 uncovered end face, and clamp 4 lower ends are provided with width and fall " U " shape bayonet socket 5 greater than the syringe nipple external diameter less than the needle holder external diameter.
Claims (1)
