Description

Technical Field

[0001] The invention relates to the technical field of breathing masks, in particular to a helmet-type anti-condensation breathing mask for non-invasive mechanical ventilation. Background Art

[0002] Mechanical ventilation is a ventilation method that uses mechanical devices to replace, control or change spontaneous breathing movements, with the help of a ventilator to maintain airway patency, improve ventilation and oxygenation, prevent hypoxia and carbon dioxide accumulation in the body, and enable the body to survive respiratory failure caused by the underlying disease and create conditions for the treatment of the underlying disease.

[0003] However, when the user wears the breathing mask, the user will blow hot air onto the breathing mask during breathing. Since the temperature on the breathing mask is relatively low, the hot air will be adsorbed on the breathing mask to form water mist and produce condensed water. The condensed water adheres to the mask and may drip onto the nose of the user when the user turns over at night, causing discomfort to the user, thereby reducing the comfort of use. In addition, the condensed mist inside the mask may also affect the field of vision and make the user feel inconvenient. The condensed water provides a humid environment for bacteria, making it a culture medium for bacteria. At the same time, the condensed water is the part of the ventilator pipeline that is most prone to infection and is also the part where bacteria are most likely to gather. If these bacteria enter the user's respiratory tract with the airflow, it may cause respiratory tract infection and cause harm to the user. Therefore, a helmet-type anti-condensation breathing mask for non-invasive mechanical ventilation is needed. Summary of the invention
