Abstract
The utility model belongs to the field of a medical appliance, and relates to a clinical tracheal catheter, particularly a flexible non-injury pernasal and peroral tracheal catheter. The tracheal catheter improves the traditional tracheal catheter, and the utility model is composed of a tracheal catheter top end, an inflating sac, an air injecting opening of the inflating sac, an abutting end of a breathing loop circuit of the tracheal catheter, a ring conducting wire and a ring. The tracheal catheter top end of the tracheal catheter is slightly softer than a traditional tracheal catheter wall, a tip is bent, when required, the top part of the tracheal catheter can be bent through manually pulling the ring; intubation processes can be simplified, intubation damage is decreased, and clinicians' tracheal intubation operation is convenient.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of clinical endotracheal tube of using, and is specifically related to the flexible per nasal of a kind of not damaged, per os endotracheal tube.
Background technology
Clinically, aspects such as the central respiratory function that causes at cardio-pulmonary-cerebral resuscitation, cranium disease of brain etc. goes down, acute and chronic respiratory failure, ARDS, general anesthesia control breathing, all to use the tracheal intubation technology, so this technology is the very important operating technology of serious symptom medical science, Anesthesia Department, emergency department, is the clinical skill that relevant medical worker must grasp.
The approach that tracheal intubation enters according to endotracheal tube is divided into oral trachea cannula, nasal trachea cannula and through the tracheostoma intubate.According to whether utilizing the pharyngeal anatomical structure of laryngopharyngeal mirror photopic vision, be divided into photopic vision intubation and blind tracheal intubation.Per os photopic vision tracheal intubation and per nasal photopic vision tracheal intubation all are after the operator exposes the throat anatomical structure with laryngopharyngeal mirror, to make a mouthful axle, pharynx axle, three unifications of larynx axle, reach the purpose that exposes glottis, under direct-view endotracheal tube are inserted trachea.Yet also there is many disadvantages in present endotracheal intubation, reach three real unifications and also compare difficulty.Sometimes, need utilize the harder intubate of quality to lead core and endotracheal tube is moulded " L " shape or hook-shaped, be beneficial to endotracheal tube and enter trachea by glottis, after endotracheal tube tip is by glottis, need pull out again and lead core along physiological bending.Nasal trachea cannula need endotracheal tube through the nostril, nasal vestibule, cavum nasi proprium, choana, nasopharynx part, pars oralis pharyngis, enter trachea by glottis, but there are physiological bending in nasal vestibule and nasal cavity, nasal cavity and nasopharynx part, and nasal cavity and nasopharynx part are that softness, blood are for abundant mucosa, be very easy to the mucosa of damage nasal cavity, nasopharynx during endotracheal tube process physiological bending, cause hemorrhagely, even endotracheal tube directly misplugs under the mucosa, causes severe complication.
Summary of the invention
The purpose of this utility model provides a kind of flexible not damaged endotracheal tube.This utility model endotracheal tube per nasal, oral trachea cannula, flexible, can simplify the intubate process, reduce injury of tracheal intubation, make things convenient for the operation of clinician's tracheal intubation.
The flexible not damaged endotracheal tube of this utility model improves traditional endotracheal tube, by endotracheal tube top 1, and gas cell 2, gas cell gas injection port 3, endotracheal tube is breathed loop cohesive end 4, and finger ring lead 5 and finger ring 6 constitute.Described top is long to be 4.0-5.0cm, and softer slightly than traditional endotracheal tube wall, its requirement is that intrinsic pressure at air bag is 30cmH
2Tube wall is not flattened during o, and it is provided with top end opening 1a and tip side mouth 1b, and the straight shape of the more traditional endotracheal tube of bent at its tip 1c is most advanced and sophisticated slightly crooked; Apart from catheter tip 1.5-2.5 centimeters, bonding gas cell, its length on endotracheal tube is 3-4 centimetre; Described finger ring lead origin also is fixed in the tip, walks in the endotracheal tube tube wall, and is free and make finger ring apart from tail end 7-10cm place, is inserted in for intubationist's finger, spurs latch closure and can make the top of endotracheal tube upwarp bending.
This utility model shows to have following advantage through clinic trial:
Its tip apex is bending slightly and has following meaning: 1, reduce in the endotracheal tube traveling process damage to mucous membrane tissue, especially in nasal intubation, the damage of nasal cavity and nasopharynx part mucosa not only can be reduced in Wan Qu tip slightly, and it is more convenient also endotracheal tube to be advanced; 2, the tip enters glottis easily, because vocal cords are higher than the vocal cords folds in a garment of both sides, under the situation that is difficult to photopic vision glottis structure (difficulty exposes and blind tracheal intubation), the tip of traditional straight shape withstands on vocal cords and vocal cords folds in a garment intersection easily, be difficult to enter glottis, tip bending slightly then can avoid above-mentioned phenomenon to take place, or can enter glottis after the rotation a little.
Its top quality is softer slightly than tradition, to the damage of mucosa, the top upwarps bending during the finger ring tractive, makes intubate no longer need tracheal intubation to lead core in the time of reducing endotracheal tube and advance, simplify the operation course, and can reduce when being inserted with the endotracheal tube of leading core damage glottis through glottis.
Its finger ring lead is attached to the tip, and finger ring is buckled for the operator and is inserted in finger, when needing, pulls finger ring and can make top curved, 1, oral trachea cannula enters trachea by glottis easily; 2, the per nasal blind tracheal intubation runs into physiological bending, and the pulling latch closure also can make the front end bending, makes endotracheal tube smoothly by nasal vestibule and nasal cavity, and the physiological bending that nasal cavity and nasopharynx part form enters into nasopharynx part and pars oralis pharyngis.
