Description
Technical field
The utility model belongs to digestive endoscopy detection auxiliary the field of medical instrument technology, and in particular to a kind of digestive endoscopy
With oxygen absorption type oropharyngeal airway.
Background technique
Painless digestive endoscopy checks the inspection for being applied to digestive organs more and more widely.Currently, largely painless orally disappear
Changing endoscopy or operation is that non-intubation and general anaesthesia is realized under the conditions of transnasal catheter oxygen uptake, this is because the short time
Digestive endoscopy operate when required depth of anesthesia it is not high, only with Intravenous Anesthesia rather than trachea cannula can be completed.
However, transnasal catheter oxygen-absorption efficiency is low in digestive endoscopy checking process, effect is poor, patient is caused easily to occur low
Oxygen mass formed by blood stasis threat to life safety.Meanwhile under the Intravenous Anesthesia state of not trachea cannula, patient, which is easy glossoptosis, leads to air flue
Obstruction, so that the mortality accident such as respiratory failure, cardiopulmonary arrest occur.
The effective measures of prevention and treatment glossoptosis are the application of oropharyngeal airway or nasopharyngeal air duct, but are digested at present
Existing oropharyngeal airway when endoscopic technic can not pass through digestive endoscopy and cannot provide reliable and stable because bore is meticulous
Oxygen uptake condition, it is difficult to be suitable for digestive endoscopy.
In order to solve the above-mentioned technical problem, the Chinese utility model patent of Patent No. CN 205460272U provides one
The kind weak stimulation oropharyngeal airway of digestive endoscopy, the jaw face of air passage ontology and lingual surface are respectively that uvula is recessed and tongue is central
It is recessed, to mitigate the stimulation to uvula, while tongue central sulcus being maked somebody a mere figurehead, one side of air passage ontology is that semicircular ventilation is recessed
Slot, another side are circular endoscope passage, and bite-block is arranged in end, and lip screening glass is arranged on bite-block, and vent grooves and scope are logical
Road both passes through bite-block and lip screening glass.
However, the ventilation road shape approximation conventional arched oropharyngeal airway of the patent, can make tongue tip move forward after placement
Or it is mobile toward the other side, to stop digestive endoscopy to be placed in and operate, as violence operation can damage tongue body.In addition, the patent
In vent grooves be semi-circular open channel, if wanting oxygen uptake, need additionally to place oxygen channel, and current clinical application
Oxygen channel is mostly nose conduit, is placed into rear oral cavity and is easy blocking, should not be used in oxygen uptake in oral cavity, while semi-circular opening is logical
Road is easy oxygen and leaks, and oxygen-absorption efficiency is low, and when patient respiratory inhibition occurs, it is logical cannot to be directly connected to respiratory balloon progress positive pressure
Gas.
Utility model content
