Abstract
The invention discloses a tracheal cannula. A convex point is formed from 8 centimeters below an end cuff of a patient, at intervals of 10 centimeters along one circle of the periphery of the cannula wall and at every 90 degrees; and the convex points are adapted and tightly combined with concave points of a current common disposable tooth pad, so that the tracheal cannula is stably fixed on the disposable tooth pad, the tooth pad is firmly positioned in the oral cavity of the patient, and unsmooth ventilation caused by blockage of the tracheal cannula when the patient accepts anesthesia or danger potential caused when the cannula is not firmly fixed and slips out of the oral cavity of the patient is fully overcome.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of tracheal intubation.
Background technology
Tracheal intubation is with a kind of special endotracheal tube, insert in the patient's trachea by oral cavity or nasal cavity, this apparatus and technology can provide optimum condition for airway patency, ventilation oxygen-supplying, respiratory tract attraction and prevent that mistake from inhaling etc., be a kind of endotracheal anesthesia and the technology that gives emergency treatment to a patient, tracheal intubation is important measures of rescuing the cardiopulmonary arrest patient.It is convenient to remove respiratory secretions, and it is unobstructed to keep trachea, reduces airway resistance, help reducing the respiratory tract anatomical dead space, guarantee effective ventilatory volume, for administration in oxygen supply positive pressure breathing and the trachea provides condition, trachea or endobronchial intubation are to implement safety measure of anesthesia.Therefore, respiratory arrest that a variety of causes causes or respiratory failure, the patient that need carry out artificial assisted respiartion all should use tracheal intubation and endotracheal intubation.
Urgent tracheal intubation technology has become cardio-pulmonary resuscitation and has reached with the important measures in the anxious Cavity in Critical Patients rescue process of respiratory dysfunction.Endotracheal intubation is an important rescue technology commonly used in the rescue service, be in the management of respiratory general, the most effective most widely used means the most efficiently it, be the basic skill that the medical worker must be on top of, to rescue patient life, reduce case fatality rate and play crucial effects.And trachea endocrine of sucking-off in time or foreign body, prevent that foreign body from entering respiratory tract, keep respiratory passage unblocked, carry out effectively artificial or mechanical ventilation, prevent whether patient's anoxia and carbon dioxide retention tracheal intubation be timely, direct relation that can the success or not, the patient that rescue transport safely and patient's prognosis situation.
In using the process of tracheal intubation, the time do not have fixation to skid off the patient oral cavity and the report of the danger that takes place relevant for patient's under the situation of having accepted anesthesia, killing of looking like under the tracheal intubation caused ventilating smooth or intubate.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the object of the present invention is to provide a kind of tracheal intubation, have difficult drop-off, characteristics safe in utilization.
In order to achieve the above object, technical scheme of the present invention is achieved in that a kind of tracheal intubation, it is characterized in that, from the 8 centimeter beginnings of patient end 1 cover capsule 2 below, every 10 centimeters outside tube wall Monday enclose, per 90 degree places are provided with a salient point 6.
The salient point 6 that the present invention is provided with is suitable with the concave point of disposable bite-block commonly used now, combine closely, such result is firm tracheal intubation being fixed on the disposable bite-block, and bite-block more firm in patient's oral cavity, overcome the patient fully and under the situation of accepting anesthesia, tracheal intubation killed the smooth or intubate of causing ventilating and do not have the fixation to skid off the patient oral cavity and the dangerous hidden danger that takes place.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and operation principle are described in detail.
A kind of tracheal intubation, the pipe shaft 3 that comprises hollow, the machine end 5 that the patient end 1 of pipe shaft 3 is provided with cover capsule 2, pipe shaft 3 is provided with joint 4, and pipe shaft 3 middle parts are communicated with gas tube 7, and gas tube 7 is provided with aeration 8, patient end 1 cover capsule 8 centimeters 2 below are located to begin, every 10 centimeters Monday circles outside tube wall, per 90 degree places are provided with a salient point 6, one circles and are provided with 4 salient points 6, salient point 6 is suitable with the concave point of the disposable bite-block of using always now, difficult drop-off.
Operation principle of the present invention is: disposable bite-block more firm in patient's oral cavity, the present invention inserts in the disposable facing, the suitable difficult drop-off of combining closely of concave point of salient point 6 and disposable bite-block.
Claims (1)
1. a tracheal intubation is characterized in that, from 8 centimeters following beginnings of patient end (1) cover capsule (2), every 10 centimeters outside tube wall Monday enclose, per 90 degree places are provided with a salient point (6).
