Anesthesia pump for anesthesia medicine

Abstract

The invention discloses an anesthesia pump for anesthesia medicine. The anesthesia pump includes a hollow square tube, a hollow cylinder, a piston, a connecting push rod, a press handle, a medicine inlet tube, a one-way valve, an injection head, a hose, a T-shaped bearing plate, an extrusion plate, an extrusion rod, a rotating handle, a hot water inlet tube, and a water outlet tube, wherein the hollow square tube and the right side wall of the hollow cylinder are fixedly glued, the medicine inlet tube is arranged on the side surface of the hollow cylinder, the one-way valve is fixedly glued tothe medicine inlet tube, the injection head is arranged on the left side wall of the hollow square tube, the injection head is connected to the hollow cylinder through the hose, the T-shaped bearingplate is arranged under the hose, the upper part of the hose is provided with the extrusion plate, the top of the hollow square tube is provided with the hot water inlet tube, and the bottom of the hollow square tube is provided with the water outlet tube. The anesthesia pump has the advantages that the anesthesia pump can accurately regulate the flow amount and the flow rate of the injected anesthetic and can heat the injected anesthetic liquid to make the injected anesthetic liquid more suitable for the temperature of the human body and alleviate the discomfort during injection.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anesthesia pump for anesthesia medicine. Background technique [0002] It is generally believed that anesthesia is a reversible functional inhibition of the central nervous system and (or) peripheral nervous system produced by drugs or other methods, and the main feature of this inhibition is the loss of pain sensation. Patient-controlled analgesia is a new treatment method proposed by Sechzer in the early 1970s. It is mainly used for postoperative pain and late cancer pain treatment and postpartum analgesia. An anesthesia pump (also known as an analgesic pump) is an electronically controlled injection device that can deliver constant-rate intravenous injections of painkillers at a pre-set rate. Can be used for various acute and chronic pains. The drugs in the anesthesia pump (also known as the pain relief pump) are usually anesthetics. The existing anesthesia pump (...

AI Technical Summary

Problems solved by technology

The drugs in the anesthesia pump (also known as the pain relief pump) are usually anesthetics. The existing anesthesia pump (also known as the pain relief pump) not only cannot meet the needs of rapid emergency anesthesia functionally, but also partly belongs to the integration of electronic components. It is easy to fail in the case of anesthesia. For this reason, the Chinese patent authorization announcement number is the invention patent of CN 205339726 U, which proposes a manual adjustment anesthesia pump to solve the above problems.

[0003] However, the invention cannot accurately detect and adjust the flow rate. Generally, the temperature of injection anesthesia is lower than that of the human body, and sudden injection will cause discomfort to the human body.
