Exterior pipe of hard film

Abstract

The invention relates to a medical treatment apparatus, in particular to an epidural guiding tube which comprises a malleable rubber tube. One end of the pipe is a hook bending tip and the other end is an open end. 1 to 6 orifice(s) for drug injection is/are arranged on the hook bending tip and an orifice for drug injection is arranged on the front end of the hook bending tip. A sleeve is arranged on the outside of the malleable rubber tube. The tip of the epidural guiding tube is shaped in a bending hook, so that the epidural guiding tube is not easy to penetrate putamen or blood vessel for progressing in an epidural space in the shape of a hook one-eighth bend. The diameter of the hook is bigger than (or equal to) the diameter of an intervertebral foramina and the epidural guiding tube is also strayed into the intervertebral foramina. Being positioned in a joint of the sleeve, the tip of the malleable rubber tube is in the state of extension, thus being convenient for putting the malleable rubber tube into an inner chamber of an epidural needle and favorable to protect the guiding tube away from the pollution of thimerosal, talcum powder on sterile gloves, etc.

Description

technical field [0001] The invention relates to a medical appliance, in particular to an epidural catheter for spinal canal anesthesia. Background technique [0002] The spine is the backbone of the human body, and it is also the main channel and protective cover for the transmission of nerve information. The spine, as the central part of the human body, is structurally located in the center of the body, coordinating and controlling the activities of the head and limbs. Nerves from each pair of intervertebral foramina control sensory and motor functions throughout the body. When the human body is sick and needs to perform surgery or perform diagnostic inspection operations, in order to reduce the pain of the patient, ensure the safety of the patient, and create good surgical conditions, it is necessary to anesthetize the patient. Intraspinal anesthesia is an important way of anesthesia. It injects local anesthetics into different cavities in the spinal canal to anesthetize...

AI Technical Summary

Problems solved by technology

Due to the puncture process of spinal anesthesia and the process of injecting drugs, the needle tube and catheter in the human body cannot be monitored, that is, the depth of the needle or catheter is controlled entirely by the doctor's experience and feel. The front end of the existing epidural catheter Harder, often easy to break through the dura mater or blood vessels, or through the intervertebral foramen, which will lead to anesthesia failure
