Summary
Researchers developed anatomical nasal protectors for newborns using prongs. Gamma radiation ensured the sterility and stability of the hydrocolloid material, making it safe for clinical evaluation.
Area of Science:
- Biomedical Engineering
- Materials Science
Background:
- Neonatal nasal prongs require protective devices.
- Existing solutions may pose risks or be ineffective.
Purpose of the Study:
- To design and develop an anatomical nasal protector for newborns.
- To evaluate the efficacy of different sterilization methods for the protector.
Main Methods:
- Descriptive study and technological production following the Product Development Process.
- Design phases included informational, conceptual, and detailed design (March 2017 - February 2019).
- Hydrocolloid nasal protectors were subjected to five sterilization methods: UV, gamma radiation, formaldehyde, hydrogen peroxide plasma, and steam.
Main Results:
- Nasal protectors were successfully designed and materialized using hydrocolloid plates.
- Microbiological testing revealed bacterial growth after formaldehyde and UV radiation sterilization.
- Gamma radiation demonstrated effectiveness in ensuring both sterility and material stability.
Conclusions:
- Three classifications of hydrocolloid nasal protectors were developed.
- The protectors exhibit safe and promising characteristics for further research.
- Clinical evaluation in newborns using prongs is recommended for these novel devices.

01:24Nose and Nasal Cavity
8.3K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...
