Description

A breathing mask for premature infants

technical field

The utility model relates to the technical field of medical devices, in particular to a breathing mask for premature infants.

Background technique

Premature infants often require respiratory support due to respiratory distress or respiratory failure due to immature lungs or various diseases. Respiratory support methods include non-invasive ventilation and invasive ventilation. Invasive ventilators have significantly reduced the mortality rate of premature infants with respiratory failure, but the complications such as ventilator-related lung injury and infection have seriously affected these premature infants, especially Long-term prognosis of extremely preterm infants. In order to minimize the complications of invasive ventilator ventilation, it can effectively treat respiratory failure at the same time. In recent years, clinicians tend to give priority to the early application of non-invasive ventilation, and decide whether to give invasive ventilation according to the effect of non-invasive ventilation support.

In the current clinical use, some problems in the fixation of non-invasive ventilation devices are found as follows:

1. The non-invasive ventilator fixation method is traditional, and it is fixed on the face or head by adhesive tape or cotton cloth, which is easy to damage the skin of premature infants or even skin pressure sores, and the deformation of the nose and face will affect the appearance;

2. The nasal cavity and the pipeline cannot be completely fitted even when the pipeline model is matched, and the pipeline is prone to fall off clinically, resulting in poor oxygen balance of the child and delaying treatment;

3. Babies cannot breathe through the nose with the mouth closed, causing the gas delivered by the ventilator through the nose to often leak out through the mouth, which cannot guarantee effective ventilation volume and pressure.

Therefore, how to solve the above problems has become the focus of research by those skilled in the art.
