AI Technical Summary

Technical Problem

Existing infant nasal masks cannot be individually adjusted according to the shape and size of an infant's face, resulting in an unsatisfactory fit, uneven air pressure, and affecting the effectiveness of respiratory therapy and the infant's comfort.

Method used

It adopts an air pressure detection structure, flexible airbag, inflation valve structure, flexible sponge, fixed head cover and tension adjustment component. By monitoring the air pressure in real time and adjusting the expansion of the flexible airbag and the tension of the elastic band, it ensures that the breathing nasal mask fits the baby's face and the air pressure is stable.

Benefits of technology

It improves the fit and comfort of the nasal mask to the baby's face, avoids air leakage and negative pressure, ensures the effectiveness of respiratory therapy, adapts to different baby face shapes and sizes, and prevents suffocation and discomfort.

Abstract

The application belongs to the technical field of medical devices, and specifically provides a baby respiratory nasal mask capable of adjusting the fitting degree according to the air pressure state, which comprises a respiratory nasal mask, an air pressure detection structure, a flexible air bag, an inflation valve structure, a flexible sponge, a fixed head cover and a tightness adjusting assembly; the respiratory nasal mask is connected with a breathing machine through a pipeline; the breathing machine is provided with a control module; the air pressure detection structure is installed on the respiratory nasal mask; the control module transmits an air pressure detection signal to the air pressure detection structure; the flexible air bag is installed on the end surface of the respiratory nasal mask in contact with the baby's face; the inflation valve structure is arranged on the flexible air bag; the flexible sponge is installed on the end surface of the flexible air bag away from the respiratory nasal mask; the fixed head cover is connected with the respiratory nasal mask through an elastic band; and the tightness adjusting assembly is installed on one end of the elastic band located on the fixed head cover. The tightness adjusting assembly drives the elastic band to adjust the tightness between the respiratory nasal mask and the baby's face to adapt to different babies.
