Description

Tracheotomy rehabilitation occluder

Technical Field

The utility model relates to the technical field of medical devices, in particular to a tracheotomy rehabilitation occluder.

Background Art

Tracheotomy is an important emergency treatment technique used in the clinical treatment and rescue of critically ill patients with airway obstruction caused by various reasons. It opens the airway, which is conducive to ventilation and supplementary oxygen supply. This plays an extremely important role in saving the patient's life, improving the patient's prognosis and quality of life, and achieving successful treatment of critically ill patients. After tracheotomy, the patient's ventilation route changes, an artificial airway is established, and air directly passes through the tracheotomy opening for gas exchange. The patient loses the function of the nose to warm, humidify and block dust. The invisible water loss of the airway is huge, the infection rate increases, and the complications increase significantly. After the patient is out of critical condition, the airway obstruction is relieved or the lung infection is controlled, the doctor will often consider removing the tracheal cannula, closing the artificial airway, and reducing clinical complications. However, many patients are accustomed to artificial airways. After the tracheal tube is closed, the ventilation through the mouth and nose is insufficient and cannot be tolerated. The patients experience chest tightness and shortness of breath, increased heart rate, decreased blood oxygen saturation, and even a feeling of suffocation. Therefore, before removing the tracheotomy tube, medical staff usually need to gradually test the tracheotomy tube, starting from blocking 1/3 of the tracheotomy and slowly transitioning to half-blocking the tube, until the tube is completely blocked. After blocking the tube, encourage the patient to go up and down the stairs without shortness of breath, and the blocking of the tube is successful if the vital signs are stable. The purpose of the test blocking is to observe whether the patient can stop direct airway ventilation, safely and smoothly transition to normal mouth and nose breathing, and finally close the tracheotomy opening.

The existing tracheotomy rehabilitation occluder does not have a pressure relief function. During the occlusion process, the patient's air intake is limited, and the pressure cannot be relieved in time when the patient cannot bear it.

It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention.
