Anesthetic drop syringe

Abstract

An anesthetic drop syringe comprises a hollow square tube, a hollow cylinder, a piston, a connecting push rod, a handle, a medicine feeding tube, a one-way valve, an injection head, a hose, a T-shapedcarrier plate, a pressing plate, a pressing bar, a rotating handle, a hot water inlet pipe and an outlet pipe, wherein the hollow square tube is fixed to the right side wall of the hollow cylinder byan adhesive; the medicine feeding tube is arranged on the side of the hollow cylinder; the one-way valve is glued and fixed to the medicine feeding tube; the injection head is arranged on the left side wall of the hollow square tube; the injection head communicates with the hollow cylinder through the hose; the T-shaped carrier plate is arranged under the hose; the pressing plate is arranged above the hose; the top of the hollow square tube is provided with the hot water inlet pipe; and the bottom of the hollow square tube is provided with the outlet pipe. The syringe precisely controls the flow and the flow rate of an injected medicine, and can heat the injected medicine to make the injected medicine adapt to body temperature and relieve discomfort during injection.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to an anesthetic drip syringe. 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. The main characteristic of this inhibition is the loss of pain. Patient controlled analgesia is a new treatment method proposed by Sechzer in the early 1970s. It is mainly used for postoperative pain and cancer pain treatment and postpartum analgesia. The anesthesia pump (also known as the analgesic pump) is an electronically controlled injection device that can perform constant-rate intravenous injection of analgesics at a preset speed. It can be used for various acute and chronic pain. The drugs in anesthesia pumps (also known as analgesic pumps) are usually anesthetics. The existing anesthesia pumps (also known as analgesic pumps) a...

AI Technical Summary

Problems solved by technology

The drugs in the anesthesia pump (also known as the pain pump) are usually anesthetics. The existing anesthesia pump (also known as the pain 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

At the same time, the existing equipment cannot accurately detect and adjust the flow rate. Generally, the temperature of the injected medicine is lower than that of the human body, and sudden injection will cause discomfort to the human body.
