Optical fiber for administration

Abstract

An optical fiber for administration comprises an administration tube and a conductive optical fiber body. The administration tube and the conductive optical fiber body are embedded together through an insulating material. The front end of the administration tube is a blind end, namely the end where the optical fiber body emits light. The portion, close to the blind end, of the administration tube, is provided with a medicine spray hole. The outer wrapping insulating material is also provided with a medicine spray hole corresponding to the medicine spray hole of the administration tube. The administration tube penetrates out of the end, connected with a power supply, of the optical fiber body. By the adoption of the optical fiber for administration, thyrocricocentesis can be avoided, medicine can be sprayed through the epiglottis, the glottis and the trachea in sequence, no obvious pain stimulation exists, the whole airway is in a good narcotic state, and the stress response to endotracheal intubation is greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a drug delivery optical fiber, which is used for injecting local anesthetics into the trachea and reducing the stress response of tracheal intubation. Background technique [0002] At present, in order to reduce the response of the trachea during blind intubation, in addition to intravenous injection of a small amount of sedative and analgesics, local anesthetics are also injected into the cricothyroid membrane. Cough, the more important thing is that puncture can easily cause tracheal injury, especially when the cricothyroid membrane is not positioned accurately. Contents of the invention [0003] The purpose of the present invention is to provide a drug delivery optical fiber, which can avoid cricothyroid membrane puncture, and can spray medicine sequentially through the epiglottis, glottis and trachea without obvious pain stimulation, so that the whole airway can rea...
