Description

Ventilation mask with chin strap

technical field

The utility model relates to a ventilation mask, in particular to a ventilation mask with a mandibular strap.

Background technique

Non-invasive positive pressure ventilation (NIPPV) refers to the need for invasive or invasive endotracheal intubation or tracheotomy, just through the nasal mask, mouth and nose mask, full face mask or head mask, etc. A technique for positive pressure assisted ventilation connected to a ventilator. NIPPV is often used in the treatment of respiratory failure and chronic obstructive pulmonary disease (COPD), which can effectively reduce the intubation rate of patients with acute respiratory failure, shorten the time of invasive ventilation, and reduce the length of hospitalization and treatment costs. However, while it is used as a treatment method, it also brings some unavoidable common complications to patients. Mask air leakage affects the patient's comfort and treatment effect, and is the main factor affecting the patient's poor tolerance. Severe cases can lead to failure of non-invasive ventilation therapy and intubation due to disease progression. Mask leak is affected by the size of the mask and how accurately it fits.

At the same time, for patients with chronic respiratory failure, non-invasive ventilators are often the "standard configuration", while for patients who are unconscious and open their mouths to breathe, they cannot breathe effectively in accordance with the rhythm of breathing, which will cause a large amount of gas to enter the digestive tract, causing gastrointestinal Complications such as gas or bloating and abdominal pain can occur.
