Abstract
The utility model relates to the technical field of traditional Chinese medical appliances, in particular to a power-assisted anesthetic syringe, which comprises a syringe consisting of a needle tube, a piston, a push-pull rod, a needle seat and a needle. The power-assisted anesthetic syringe is characterized in that the power-assisted anesthetic syringe is provided with a retracting spring, a positioning rod, an ejector plate, a retracting button and a hinge shaft, the retracting spring is arranged on the lateral face of the needle tube, one end of the retracting spring is fixedly connected with the needle tube, the other end of the retracting spring is fixedly connected with the push-pull rod, a positioning groove is arranged on one side of the rear of the push-pull rod, the positioning rod is arranged in the positioning groove and hinged to the push-pull rod through the hinge shaft, one end of the positioning rod is hinged to the retracting button, the other end of the positioning rod is connected with the ejector plate, the retracting button is connected with the push-pull rod in a threaded manner, the ejector plate at the other end of the positioning rod is abutted to an end of the needle tube to lock the push-pull rod by means of clockwise rotating the retracting button, the ejector plate at the other end of the positioning rod is separated from the needle tube by means of anticlockwise rotating the retracting button, and accordingly, the push-pull rod injects medicines by the aid of automatic retraction of the retracting spring. Owing to the structure, the power-assisted anesthetic syringe has the advantages of being reasonable in structure, convenient to operate, safe in use, time-saving, labor-saving and the like.
Description
Technical field
This utility model relates to traditional medical utensil technical field, specifically a kind of anesthetic syringe with power-assisted.
Background technology
So-called nerve block anesthesia (conduction anaesthesia) is that local anaesthetics is expelled near peripheral nervous does, through the conduction of block nerves impulsion, the regional anesthesia that this nerve is arranged; Nerve block anesthesia is a kind of little to patient trauma, and dangerous little, price is relatively cheap; The anesthesia of effect is used common syringe usually during injection, it is made up of needle tubing, piston, push-pull bar, needle holder and syringe needle; The needle tubing front end is connected with syringe needle through needle holder, is provided with piston in the needle tubing, and piston rear end is connected with push-pull bar; Push-and-pull through push-pull bar; Can or get rid of needle tubing with the medicinal liquid inspiration, deficiency is: relatively requiring great effort during injection, also is a kind of damage even use needle tubing injection a period of time of 5 milliliters to the hands of anaesthetizing the doctor.
Summary of the invention
The purpose of this utility model is the deficiency that solves above-mentioned prior art, and a kind of anesthetic syringe of rational in infrastructure, easy to operate, safe in utilization, time saving and energy saving band power-assisted is provided.
This utility model solves the technical scheme that its technical problem adopted:
A kind of anesthetic syringe with power-assisted comprises syringe, and syringe is made up of needle tubing, piston, push-pull bar, needle holder and syringe needle; It is characterized in that being provided with retraction spring, locating rod, top board, retraction button and hinge, retraction spring is located at the needle tubing side, and retraction spring one end is fixedly connected with needle tubing; The other end is fixedly connected with push-pull bar, and push-pull bar rear portion one side is provided with detent, is provided with locating rod in the detent; Locating rod is hinged through hinge and push-pull bar, and locating rod one end is hinged with the retraction button, and the other end is connected with top board; The retraction button is threaded with push-pull bar, and through the retraction button that turns clockwise, the top board of the locating rod other end is against syringe tip; To pin push-pull bar; Be rotated counterclockwise the retraction button, the top board of the locating rod other end breaks away from needle tubing, makes push-pull bar carry out injection by the automatic retraction of retraction spring.
This utility model has advantages such as rational in infrastructure, easy to operate, safe in utilization, time saving and energy saving owing to adopt said structure.
Description of drawings
Accompanying drawing is the structural representation of this utility model.
Reference numeral: needle tubing 1, piston 2, push-pull bar 3, needle holder 4, syringe needle 5, retraction spring 6, locating rod 7, top board 8, retraction button 9, hinge 10, detent 11.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further specified:
Shown in accompanying drawing, a kind of anesthetic syringe with power-assisted comprises syringe; Syringe is made up of needle tubing 1, piston 2, push-pull bar 3, needle holder 4 and syringe needle 5, it is characterized in that being provided with retraction spring 6, locating rod 7, top board 8, retraction button 9 and hinge 10, and retraction spring 6 is located at the needle tubing side; Retraction spring 6 one ends are fixedly connected with needle tubing 1, and the other end is fixedly connected with push-pull bar 3, and push-pull bar 3 rear portions one side is provided with detent 11; Be provided with locating rod 7 in the detent 11, locating rod 7 is hinged through hinge 10 and push-pull bar 7, and locating rod 7 one ends are hinged with retraction button 9; The other end is connected with top board 8, and retraction button 6 is threaded with push-pull bar 3, through the retraction button that turns clockwise; The top board 8 of locating rod 7 other ends is against needle tubing 1 end, to pin push-pull bar 3, is rotated counterclockwise retraction button 9; The top board 8 of locating rod 7 other ends breaks away from needle tubing 1, makes push-pull bar 3 carry out injection by the automatic retraction of retraction spring 6.
This utility model is rotated counterclockwise retraction button 9 in use, makes locating rod 7 break away from needle tubing 1; After the injection, the retraction button 9 that turns clockwise makes the top board 8 of locating rod 7 other ends be against needle tubing 1 end in needle tubing 1; Anaesthetize position injection to the patient then, in syringe needle is pricked into patient's body, rotate back to the button that contracts again counterclockwise; The top board 8 of the locating rod other end breaks away from needle tubing 1, makes push-pull bar 3 carry out injection by the automatic retraction of retraction spring 6.
This utility model has advantages such as rational in infrastructure, easy to operate, safe in utilization, time saving and energy saving owing to adopt said structure.
