Multichannel oropharyngeal ventilator for anesthesiology department

Abstract

The invention relates to the technical field of medical devices, and specifically relates to a multichannel oropharyngeal ventilator for anesthesiology department. The multichannel oropharyngeal ventilator for the anesthesiology department comprises an arcuate fixing cover, a ventilation pipe, a gas injection pipe, an air purification film, a conical liquid reservoir, an arc plate, ear-hangings, ahose, a tongue pressing plate and an arc transverse plate; the ventilation pipe transversely penetrates through the middle of the arcuate fixing cover; connecting caps formed with threads on inner walls are arranged at both the front end and the rear end of the ventilation pipe; the air purification film is arranged at where the connecting cap arranged at the front contacts with the gas injectionpipe; soft branch pipes and a connecting pipe are arranged at the front of the ventilation pipe; and the bottom of the connecting pipe is in threaded connection with the conical liquid reservoir. Themultichannel oropharyngeal ventilator for the anesthesiology department is capable of avoiding the phenomenon of occlusion of the ventilation pipe by teeth of a patient during long-time ventilation,so that, normal ventilation is ensured. Moreover, various operations, such as gastric intubation, sputum aspiration and the like, can be performed by the same apparatus; and aspirated sputum can alsobe collected. In addition, air breathed out by the patient can be purified by the arranged air purification film so as to reduce influence of air impurities on patient health.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-channel oropharyngeal ventilator for anesthesiology. Background technique [0002] The respiratory system is a general term for the organs that perform gas exchange between the body and the outside world. The function of the respiratory system is mainly to exchange gas with the outside world, exhale carbon dioxide, inhale fresh oxygen, and complete the exhalation of the old and the inhalation of the new. The respiratory system includes the airways (nasal cavity, pharynx, larynx, trachea, bronchi) and lungs. Respiratory systems in other animals such as insects function very simply, and in amphibians their skin is even vital for gas exchange. Plants also have a respiratory system, but the directionality of gas exchange can be opposite to that of animals, and the stomata on the back of plant leaves are also part of their respiratory system.

Problems solved by technology

[0005] Although the pharyngeal ventilation device provided by the above-mentioned patent documents can ensure the normal breathing of the patient, it cannot perform operations such as gastric tube insertion and sputum suction under the same device, and its functions are relatively single.

Furthermore, when the patient is ventilating for a long time, the facial muscles may be fatigued, and then the phenomenon of teeth occlusal on the ventilator may occur, which will affect the normal progress of pharyngeal ventilation.
