Description

TECHNICAL FIELD

[0001] The present application relates to anesthetic injector with mixing function. BACKGROUND

[0002] In order to achieve the desired anesthetic effect, several different anesthetic drugs or techniques are used simultaneously or successively in current clinical anesthesia to obtain general anesthesia. This simultaneous or successive application of two or more general anesthetic drugs or anesthesia techniques to achieve analgesia, muscle relaxation, autonomic reflex inhibition and maintenance of stable vital signs is called combined anesthesia.

[0003] Combined anesthesia emphasizes combination of drugs, which not only maximizes the pharmacological effects of each drug, but also reduces the dosage and side effects of each drug. This method plays a very important role in improving anesthesia quality, ensuring patient safety and reducing medical costs, etc. However, when multiple drugs are used simultaneously for anesthesia, they are usually mixed in advance and then injected through a syringe.

[0004] However, this conventional operation has obvious drawbacks. Because the physical and chemical properties such as density, solubility and pH of different drugs are different, the mixed drugs are prone to stratification after a period of time. Stratified drugs not only affect the accuracy of the dose during injection, but also may cause differences in drug onset time and effect, thereby reducing anesthesia quality and increasing anesthesia risk, which poses a potential threat to the patient's life safety and the smooth progress of the operation. SUMMARY

[0005] In view of the deficiencies in the prior art, the present application provides an anesthetic injector with mixing function to solve the technical problem that the existing anesthetic injection is mostly performed by sucking the mixed drugs into the syringe for injection, which may cause stratification of the mixed drugs due to the different physical properties of the drugs after a period of time, thereby affecting anesthesia quality and increasing anesthesia risk.
