Novel anesthetic needle device capable of continuous injection for an anesthesiology department

Abstract

The invention discloses a novel anesthetic needle device capable of continuous injection for an anesthesiology department. The device comprises a shell, an inner cavity is formed in the shell, a pressure transducer is arranged on the side surface of the inner cavity, a PLC is arranged on the side surface of the shell, a liquid outlet pipe is arranged in the position, close to the bottom surface, of the side surface of the shell, a second electromagnetic valve is arranged on the side surface of the liquid outlet pipe, the end portion of the liquid outlet pipe is provided with a connecting hose,a needle tube base is arranged on the end portion of the connecting hose, and a needle tube is arranged at the center of the side surface of the needle tube base. According to the novel anesthetic needle device capable of continuous injection for the anesthesiology department, the structure is reasonable, the practicability is high, and through a micro pressure pump, the liquid outlet pipe, the inner cavity, the connecting hose and the PLC, continuous injection can be conducted through an anesthetic needle; through the micro pressure pump, the pressure transducer and the PLC, the injection speed of the anesthetic needle is conveniently adjusted; through an observation window, the injection amount of the anesthetic needle and the residual amount in the inner cavity are conveniently observed, and accordingly the device is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of anesthesia appliances, in particular to a novel continuous injection anesthesia needle device for anesthesia. Background technique [0002] At present, the anesthesia needles used in hospitals can also be called hard waist anesthesia needles, which belong to the traditional structural form that has not changed for many years. The specific operation during anesthesia is more troublesome. The operation time is long, and the anesthesia plane is not easy to adjust. [0003] For example, the patent application publication number CN 202113136 U discloses an anesthetic needle device, which consists of a spinal anesthesia needle, a needle tube body, a needle tube seat, a needle handle and an epidural catheter. The needle tube body is the main part of the present invention, and the whole body is hollow The cylindrical structure of the needle tube body is provided with a needle tube seat at the rear end of the nee...

[0002] At present, the anesthesia needles used in hospitals can also be called hard waist anesthesia needles, which belong to the traditional structural form that has not changed for many years. The specific operation during anesthesia is more troublesome. The operation time is long, and the anesthesia plane is not easy to adjust

[0003] For example, the patent application publication number CN 202113136 U discloses an anesthetic needle device, which consists of a spinal anesthesia needle, a needle tube body, a needle tube seat, a needle handle and an epidural catheter. The needle tube body is the main part of the present invention, and the whole is hollow. The cylindrical structure of the needle tube body is provided with a needle tube seat at the rear end of the needle tube body, which penetrates into the needle tube body, and a spinal anesthesia needle and an epidural catheter are arranged side by side, and a needle handle is connected to the rear end of the spinal anesthesia needle. simple, less practical
