Abstract

The utility model provides a medical anesthetic syringe, which comprises a needle (1), a needle socket (2), a needle tube (3) and a push rod (4). The needle (1) is connected with a liquid outlet end of the needle tube (3) through the needle socket (2), one end of the push rod (4) is provided with a piston (5) and positioned in the needle tube (3), liquid outlet pores are distributed on the outer wall of the needle (1) close to a needle tip, scale marks are arranged on the outer wall of the needle (1) and behind the liquid outlet pores, and a support leg frame (8) is sleeved on the needle tube (3). When the medical anesthetic syringe is used for anesthetic injection, the needle inserting depth and dosage can be controlled accurately, drugs are administrated evenly, and an infusion part of a patient can be positioned reliably so that the best anesthetic effect can be achieved.

Description

Medical anesthetic syringe

Technical field

This utility model belongs to technical field of medical instruments, is specifically related to a kind of medical anesthetic syringe.

Background technology

Existing medical anesthetic syringe has repeatedly used metal or glass syringe; The also plastic injector of property use once; Mainly form by syringe, push rod and pin; One end of push rod band piston is positioned at syringe, and the airtight liquid outlet end that is socketed in syringe of syringe needle also has pin and syringe are made as one.During injection, hold syringe by doctor's one hand usually and have an acupuncture treatment, the acupuncture treatment degree of depth and dosage can only lean on the doctor to control with the personal experience, cause the thing of malpractice to happen occasionally deeply or to drug overdose because of having an acupuncture treatment in clinical; Had an acupuncture treatment shallow or the dosage deficiency does not reach the anaesthetic effect of application again.Secondly, existing anesthetic needle is tiny smooth surface, the drug at the needle point place only during injection; Administration is slow, and is inhomogeneous, occurs the unfavorable phenomenon of local anesthesia sometimes; Bring misery for the patient who undergos surgery, influence doctor-patient relationship, reduced medical personnel's work efficiency.In addition, when doctor's one hand was held syringe and had an acupuncture treatment, hands had rocking in various degree unavoidably, and the position that causes having an acupuncture treatment is inaccurate, influences anaesthetic effect even causes malpractice.

The utility model content

The purpose of this utility model provides a kind ofly can accurately control the acupuncture treatment degree of depth and dosage, and administration is even, and the acupuncture treatment position can reliable localized medical anesthetic syringe.

For this reason; The medical anesthetic syringe of this utility model design includes syringe needle, syringe needle socket, needle tubing and push rod, and syringe needle links to each other with the liquid outlet end of needle tubing through the syringe needle socket; One end of push rod has piston and is positioned in the needle tubing; Syringe needle is distributed with the fluid aperture near the outer wall of needle point, and the syringe needle outer wall is provided with scale in the rear of fluid aperture, is with support foot rest on the needle tubing.

When anaesthetizing injection; After finding the position that needs acupuncture treatment accurately, with support foot rest be resisted against need the acupuncture treatment position around, again the inserting needle orientation is finely tuned; So just can aim at the acupuncture treatment position fast and accurately, and can guarantee that in pushing away the liquid process needle tubing and syringe needle do not shake; The anesthesia medicinal liquid not only flows out from needle point, also in said fluid aperture, flows out, and fluid is fast, can be more equably to diffusion all around, and administration is even; The acupuncture treatment degree of depth can accurately be controlled according to scale, thereby reaches best anaesthetic effect.

Support foot rest has two retractable supports feet, and the end of feet is connected with sucker, is convenient to like this according to different acupuncture treatment positions the length of feet regulated, and sucker is adsorbed on body surface, makes the more stable support needle tubing of support foot rest.

Piston is provided with the dentation annular groove, and the bar portion of push rod is provided with annular protrusion, and annular protrusion contacts with the inwall of needle tubing.The dentation annular groove increases the elasticity of piston, makes it to paste mutually with needle interior wall more closely, strengthens its sealing.Annular protrusion on the push rod has reduced the contact area between push rod and the needle interior wall, has so both guaranteed push rod steadily moving in needle tubing, has reduced friction again, makes mobile smooth and easy.

Use this utility model to anaesthetize injection, can accurately control the acupuncture treatment degree of depth and dosage, give and want evenly, and can reliably locate, to reach best anaesthetic effect the acupuncture treatment position.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done further explain.

Referring to Fig. 1, Fig. 3; A kind of medical anesthetic syringe has syringe needle 1, syringe needle socket 2, needle tubing 3 and push rod 4, and syringe needle 1 links to each other with the liquid outlet end of needle tubing 3 through syringe needle socket 2; One end of push rod 4 has piston 5 and is positioned at 3 li of needle tubings; Syringe needle 1 is distributed with fluid aperture 6 near the outer wall of needle point, and syringe needle 1 outer wall is provided with scale 7 in the rear of fluid aperture 6, is with support foot rest 8 on the needle tubing 3.

When anaesthetizing injection; After finding the position that needs acupuncture treatment accurately, with support foot rest 8 be resisted against need the acupuncture treatment position around, again the inserting needle orientation is finely tuned; So just can aim at the acupuncture treatment position fast and accurately, and can guarantee that in pushing away the liquid process needle tubing 3 and syringe needle 1 do not shake; The anesthesia medicinal liquid not only flows out from needle point, and also from 6 li outflows of fluid aperture, fluid is fast, can be more equably to diffusion all around, and administration is even; The acupuncture treatment degree of depth can accurately be controlled according to scale, thereby reaches best anaesthetic effect.

Referring to Fig. 2; Support foot rest 8 has two retractable supports feet, and the end of feet is connected with sucker 9, is convenient to like this according to different acupuncture treatment positions the length of feet regulated; Sucker 9 is adsorbed on body surface, makes the more stable support needle tubing 3 of support foot rest 8.

Referring to Fig. 1, piston 5 is provided with dentation annular groove 10, and the bar portion of push rod 4 is provided with annular protrusion 11, and annular protrusion 11 contacts with the inwall of needle tubing 3.Dentation annular groove 10 increases the elasticity of piston 5, makes it to paste mutually with needle tubing 3 inwalls more closely, strengthens its sealing.Annular protrusion 11 on the push rod 4 has reduced the contact area between push rod 4 and needle tubing 3 inwalls, has so both guaranteed that push rod 4 moved at the steady of 3 li of needle tubings, has reduced friction again, makes mobile smooth and easy.
