Description

Painless gastroscopy airway management system

Technical Field

The invention relates to the technical field of medical detection auxiliary instruments, in particular to an painless gastroscopy airway management system.

Background

The painless gastroscopy is to administer a certain dose of short-acting anesthetic through veins to help a patient to quickly enter a calm and sleep state, complete the gastroscopy in no feeling, and quickly recover after the examination is finished. After anesthesia, many patients, particularly obese patients and patients with sleep apnea, experience severe airway obstruction or even failure to ventilate due to glossoptosis and relaxation of the oropharyngeal muscles, resulting in oxygen saturation due to insufficient supply. Some airway obstruction can be resolved by lifting the mandible, but some patients still require the intervention of upper airway ventilation tools to relieve the obstruction, and even threaten the life safety of the patients when the hypoxia is severe, and the process of treating the airway can seriously interfere with or even require the suspension of the gastroscopy process.

1) The mouth piece aggravates the tongue tenesmus in order to prevent that the involuntary bite of patient can produce the damage to the gastroscope mirror body, can regularly place the mouth piece when patient is awake, this is the cavity of centre and can supplies the short pipeline of bite-block class of gastroscope to pass through, its shortcoming can push the tongue backward, it is little to the patient of clear-headed and no respiratory tract obstruction risk, but for the patient after the anesthesia and or have respiratory tract obstruction risk (such as obesity), anesthesia itself all can lead to tongue tenesmus and pharyngeal muscle relaxation, the use of mouth piece pushes the tongue backward again, thereby aggravates respiratory tract obstruction. To this kind of condition, generally can use the oropharynx air vent, the oropharynx air vent is the non-tracheal tube nature of a clinical nothing and does not have the wound air vent, can push the tongue forward from the tongue back, alleviates tongue tenesmus, and open the air flue obtains effectual breathing in, avoids the people tongue tenesmus to cause the trachea to block up and suffocate when anaesthetizing. However, the airway tube inside the existing conventional oropharyngeal airway is too small to allow passage of a gastroscope, and therefore cannot be performed simultaneously with the gastroscopy, and cannot be inserted while the patient is awake because of the vomiting reflex that can be caused.

2) Problems not completely solved by emerging tools to solve the above problems, oropharyngeal airways have been created that can pass gastroscopes, to some extent solving the problem of airway obstruction, but have a number of disadvantages. In the using process, the situation of the oropharynx and the larynx can not be detected when the gastroscope directly faces to the glottis and the esophagus opening after passing through the oropharynx air duct under the ideal state. Furthermore, it is not flexible enough to use, and if such oropharyngeal airway is not placed before the examination begins, the gastroscope must be withdrawn and replaced once the airway is obstructed during the examination, which seriously affects the examination procedure. b intraductal end passes behind the throat and the trachea butt joint, insert comparatively deeply, then gastroscope or bronchofiberscope enter into the human body through this oropharynx breather pipe and examine, from the inside region to the throat of oral cavity like this, these two kinds of endoscopes are all in oropharynx breather pipe, just can not observe the condition of throat, can not examine the pathological change of throat, this oropharynx breather pipe is exclusively used for establishing the air duct simultaneously, be used for establishing the passageway usefulness for endoscopy specially, its inside space is little, the scope has occupied most space after inserting, its flow of ventilating also receives the influence, not very suitable gastroscope inspection uses. c is the same as the defect of the common oropharyngeal airway, once the oropharyngeal airway is not placed well, the only vent hole at the front section can be blocked by soft tissues, so that the ventilation can not be realized.

3) In view of the above, there is a need for a new tool, and there is a need for a dedicated airway management system for oral painless gastroscopy, which satisfies the following conditions: 1. the mouth-biting function and the oropharynx air duct function are combined, the mouth-biting function is put into a patient when the patient is awake, and whether the patient is put into the oropharynx air duct or not can be considered according to the airway condition of the patient after anesthesia and gastroscopy are started; 2. the flexible application does not influence the gastroscopy process, can be placed and taken out in any gastroscopy process, and does not occupy the channel with the gastroscopy; 3. has the functions of oxygen ventilation and sputum suction, is convenient for supplying oxygen through the oropharyngeal airway and sucking oropharyngeal secretions, and reduces the choking cough caused by the secretion sucked into the trachea. 4. The porous design prevents the main pipeline from being incapable of ventilating after the opening is blocked. In summary, the main objective is to facilitate post-anesthesia airway management while improving the efficiency of the gastroscopy and also to a great extent the safety factor of the patient.
