Mouth-lip fitting type oropharyngeal airway and application method thereof

Abstract

The invention relates to a mouth-lip fitting type oropharyngeal airway and an application method thereof. A reinforced connection ring is fixedly installed on the outer wall of a limit joint tube; anairbag ring is fixedly installed on the outer wall of the reinforced connection ring; the top of the airbag ring is provided with an airbag valve connector; an adsorption tube is fixedly installed ina vent pipe; the top of the adsorption tube is arranged on the outer side of the limit joint tube; a chamfered softened joint is fixedly installed on the outer side at the bottom of the vent pipe; anda tooth-tongue protecting washer is fixedly installed on the outer wall of the vent pipe at the lower part of the airbag ring. Thus, abrasion to mucosa can be relieved; even if liquid such as salivagenerated by foreign body sensation, the adsorption tube can be used to perform rapid adsorption; more important, the adsorption tube can be placed at the front or middle position to use; and throughthe utilization of the inner cavity of the isolated vent pipe, adsorption can be performed on the premise of not influencing other vent pipe inner cavity pipes to place in, therefore, risks during using can be reduced, and safety factors can be greatly enhanced.

Description

technical field [0001] The invention relates to the medical field, in particular to a lip anastomotic oropharyngeal airway and a method for using the same. Background technique [0002] Oropharyngeal airway placement is indicated for upper airway obstruction caused by tongue retrograde. Choose a suitable oropharyngeal tube. After implanting in the oral cavity, the tongue can leave the posterior pharyngeal wall, forming a gap between the tongue and the palate to the upper oropharynx, so that the gas can enter the trachea and keep the airway unobstructed. When using, choose the supine position, and suck the secretions from the mouth and throat. Choose an oropharyngeal tube of the size equivalent to the distance from the patient's incisors to the mandibular angle. The correct position is that the front end of the oropharyngeal tube is at the base of the tongue on the epiglottis. Test the artificial airway for patency and prevent the tongue or lips from being caught between t...

Problems solved by technology

Advantages and disadvantages of oropharyngeal airway tube placement: the advantages are easy insertion, convenient and rapid use, and can prevent airway obstruction caused by soft tissue relaxation of the tongue and pharynx; Misplacement and slippage, easy to cause laryngospasm, can cause damage to the tongue and teeth

[0003] It can be seen that the traditional oropharyngeal airway has certain disadvantages in use: first, due to the structural design of the traditional oropharyngeal airway, it is bound to cause certain damage to the throat wall during use. The design of the oropharyngeal airway is more obvious. The structure of the bent part of the bottom will cause damage when the front part of the bottom enters, and then cause nausea and vomiting, and produce a large amount of saliva and body fluids. If these liquids are not cleaned during use, It will cause serious consequences; secondly, the top limit end of the oropharyngeal airway with traditional structure is small. When in use, once the oropharyngeal airway of appropriate size cannot be selected, the risk of inhalation of the patient will increase, resulting in greater Necessary trouble; Thirdly, the traditional oropharyngeal airway is easy to move up and down and horizontally during the use stage, and even slips in severe cases, which not only increases the risk of inhalation, but also causes secondary insertion, which brings pain to the patient; In addition, the traditional oropharyngeal airway is easy to cause laryngospasm, and after insertion, due to the structure of the hard debris material, it can cause damage to the tongue and teeth, especially the parts around the teeth that are in contact with each other, which is easy to cause damage
