Abstract
A medical anesthetic syringe belongs to the technical field of medical devices, and the medical anesthetic syringe consists of a syringe (1) and a limiting bushing (2), and is characterized in that a liquid outlet hole is arranged in a syringe needle to be close to a needle tip, and the outer wall of the syringe needle behind the liquid outlet hole is provided with a scale mark; and the outside of a syringe tube is connected with the limiting bushing (2) with a circular hem on the front end in a threading way. The medical anesthetic syringe is simple in structure and convenient to use, not only is the puncture depth accurately controlled, but also the anesthetic medicine can quickly flow out from the needle tip and the liquid outlet hole and can be uniformly scattered to the periphery, so that the optimum anesthetic effect can be realized.
Description
Technical field: this utility model belongs to technical field of medical instruments, specifically a kind of medical anesthetic syringe.
Background technology: existing anesthetic syringe mainly is made up of syringe, push rod, piston, syringe needle; Holding syringe by doctor's one hand during injection has an acupuncture treatment; The acupuncture treatment degree of depth and dosage can only lean on the doctor to control with the personal experience; Had an acupuncture treatment shallow or the dosage deficiency does not reach the anaesthetic effect of application, had an acupuncture treatment dark or cause the generation of malpractice easily for drug overdose.And existing anesthesia syringe needle is at when injection drug at the needle point place only, and administration is slow, inhomogeneous, occurs the unfavorable phenomenon of local anesthesia sometimes, brings misery for the patient who undergos surgery, and influences doctor-patient relationship, has reduced medical personnel's work efficiency.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of and can not only accurately control the acupuncture treatment degree of depth, and the medical rapidly and uniformly anesthetic syringe of administration.
The purpose of this utility model is achieved in that this medical anesthetic syringe is made up of syringe, spacing collar, it is characterized in that near needle point syringe needle above be provided with liquid outlet, the syringe needle outer wall of liquid outlet back is provided with scale mark; The syringe external screw-thread is connecting the spacing collar that front end is provided with circular fold.
During use, rotary spacing sleeve as required, the needle length of exposing spacing collar is the degree of depth of acupuncture treatment.
The advantage of this utility model: simple in structure, easy to use, can not only accurately control the acupuncture treatment degree of depth, and the anesthetics fluid power flows out in needle point and the liquid outlet fast and equably to around diffusion, thereby reach best anaesthetic effect.
Description of drawings: accompanying drawing 1 is the structural representation of this utility model.
The specific embodiment: describe in further detail below in conjunction with 1 pair of this utility model of accompanying drawing: this medical anesthetic syringe is made up of syringe 1, spacing collar 2; It is characterized in that the syringe needle outer wall of liquid outlet back is provided with scale mark near being provided with liquid outlet above the tip needle; The syringe external screw-thread is connecting the spacing collar 2 that front end is provided with circular fold.
