Description

High-flow temperature humidifying oxygen therapy joint for tracheotomy patient Technical Field The invention relates to the technical field of medical appliances, in particular to a high-flow temperature and humidity oxygen therapy joint for a tracheotomy patient. Background Tracheotomy is an important measure in rescuing critical patients and maintaining the respiratory tract unobstructed. For patients after tracheotomy, it is important to provide continuous, effective and comfortable oxygen therapy. The high-flow temperature humidification oxygen therapy is used as an advanced respiratory support technology, can provide oxygen with constant concentration, and is used for heating and humidifying inhaled gas, so that the requirements of human physiology are met, airway mucosa of a patient can be effectively protected, sputum is diluted, and comfort level and treatment compliance of the patient are improved. In the prior art, when high-flow temperature humidification oxygen therapy equipment is connected with an endotracheal tube or a tracheal tube of a patient, a simple straight-through connector or a three-way connector with a side hole is generally adopted, however, the traditional connectors have the defects that firstly, the oxygen flow is strong in impact and poor in comfort, high-flow oxygen directly and intensively rushes to the airway of the patient through the straight-through connector, stronger impact and stimulation can be generated on airway mucosa, the patient is easy to choke and uncomfortable, even airway spasm is caused, especially for sensitive or awake patients, experience is poor, secondly, the problem that the exhalation resistance is large and the oxygen is wasted is solved, and when the simple three-way connector exhales, the gas exhaled by the patient can be exhausted from the side hole after being opposed to the input oxygen flow, so that the exhalation resistance is increased, and a great amount of oxygen is wasted.
