Problems solved by technology

However, the current injection method usually still uses the syringe pushed by the doctor to perform the injection, and it is difficult for the doctor to accurately control the injection volume of the anesthetic agent; in addition, when the gas is discharged from the syringe, part of the injection liquid often flows out, causing waste, and The needle part of the current anesthesia syringe is often easy to remain and easy to inject, resulting in further waste

Abstract

The invention discloses a high-precision anesthetic injector. The anesthetic injector comprises a syringe, a push rod arranged in the syringe, a push handle connected to the tail end of the push rod, a piston connected to the front end of the push rod, a slender rod connected to the front end of the piston, a finger supporting piece connected to the tail end of the syringe, a needle head connected to the front end of the syringe, a needle guard sleeved on the needle head, a puncture needle connected to the front end of the needle guard and a precise injection device arranged on the syringe. According to the high-precision anesthetic injector, by arranging the precise injection device, the high precision and micro control of the injection amount of anesthetic agents can be realized, the accuracy of the injection amount of the anesthetic agents is ensured; by arranging the match of conical needles and the needle guards, and the sealing between the conical needles and the needle sleeves is ensured, so as to prevent liquid from leaking; the purpose that gas in the syringe is discharged and agentia is discharged when the gas is discharged is realized; the waste of the agentia is avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a high-precision anesthesia syringe. Background technique [0002] At present, clinically, patients need anesthesia before surgery, and micro-injection of anesthetic agents is required for certain parts of the anesthesia. There are precise requirements for the dosage of the agents, so as to achieve better anesthesia effects and ensure the health of patients. However, the current injection method usually still uses the syringe pushed by the doctor to perform the injection, and it is difficult for the doctor to accurately control the injection volume of the anesthetic agent; in addition, when the gas is discharged from the syringe, part of the injection liquid often flows out, causing waste, and The needle part of the current anesthesia syringe is often easy to remain and easy to inject, resulting in further waste. Contents of the invention [0003] The technical problem to be s...
