PediSAL™ is a new collection device designed with the most fragile patients in mind: premature newborns. In their first days in the world it is key to identify the healthiness of the newborn, however there is little or no way to collect a sample in non-invasive fashion that does not cause the child trauma. The PediaSAL™ is a different type of collector altogether, integrating a passive collection process with soother design to not only collect but also relax the newborn. A trained individual can then take the harvested saliva sample to a number of downstream processes that look for DNA, RNA, proteins, and other components which may be of interest.
Principles of the Device
The PediaSAL™ integrates a perforated soother with a saliva sampling device. A trained individual places the soother end of the device in the mouth of the premature newborn or infant, which passively draws saliva into a soft absorptive pad as the child suckles on the soother. After a short time the pad saturates, and the healthcare worker may then remove the collection portion only, leaving the soother with the child. Saliva can then be expressed from the collection portion using a compression tube directly into any of a variety of common laboratory vials.
