Nasopharyngeal airway with visual probe

Abstract

A nasopharyngeal airway with visual probe comprises a breather pipe, one end of the breather pipe is in threaded connection with a connector, and the other end of the breather pipe is provided with aconnecting rubber pipe; an exhaust notch is formed in the connecting part of the connecting rubber pipe and the breather pipe, a visual probe is in interference fit with the interior of one end of theconnecting rubber pipe, and a wire is electrically connected to the visual probe; compared with the prior art, according to the scheme, the breather pipe is inserted more smoothly through a visual structure, meanwhile, the situation of misoperation of a doctor is reduced, and the pain of a patient is relieved; the arranged limiting clamping ring can move conveniently, it is avoided that the limiting clamping ring directly sleeves the breather pipe and causes damage to a patient in the moving process, meanwhile, rapid limiting can be achieved after sliding, and the pain of the patient is relieved; according to the invention, a doctor can adjust the breather pipe by observing the display screen, so that the doctor can adjust the plugging length of the breather pipe in a targeted manner, andthe convenience and the practicability are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a nasopharyngeal airway with a visible probe. Background technique [0002] The nasopharyngeal airway is a kind of artificial airway inserted into the pharynx through the nasal cavity. It is used to insert the pharyngeal cavity through the nasal cavity on one side to discharge the soft tissue of the pharynx cavity, achieve the purpose of upper respiratory tract ventilation, and relieve or relieve the patient's upper respiratory obstruction. smooth or obstructed. The nasopharyngeal airway is generally made of soft silicone or plastic material. It is a slightly curved cylindrical tube, similar to a non-balloon tracheal tube, but shorter, and the tube wall is thin and soft, with moderate hardness. The length varies with the inner diameter. Increase and increase; most of the existing nasopharyngeal airways are intubated by doctors based on experience. The insertion depth of ...

AI Technical Summary

Problems solved by technology

The nasopharyngeal airway is generally made of soft silicone or plastic material. It is a slightly curved cylindrical tube, similar to a non-balloon tracheal tube, but shorter, and the tube wall is thin and soft, with moderate hardness. The length varies with the inner diameter. Increase and increase; most of the existing nasopharyngeal airways are intubated by doctors based on experience. The insertion depth of the airway tube cannot be observed and cannot be adjusted according to the specific conditions of the patient. It is easy to cause blockage and poor ventilation effect situation, for this reason we provide a nasopharyngeal airway with a visual probe to solve the problems raised in the background technology
