Point-of-Birth Newborn Screening Instrument
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current newborn screening technologies require significant liquid handling and specialized technicians, leading to delays in diagnosing critical conditions, as they typically involve mailing dried blood spot specimens to laboratories for processing, which is not suitable for immediate diagnosis at the point of birth.
Innovation Solution
A portable point-of-birth testing system and instrument that includes a biochemical cartridge and a smart display, capable of performing multiplexed biochemical tests, pulse oximetry, and hearing screening, allowing for immediate analysis of newborn samples using a portable smart device or laptop, with features like barcode readers and optical detection systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional newborn screening using dried blood spot specimens mailed to laboratories is used, then specialized technicians and significant liquid handling are required, but this results in delays of a few days in diagnosing critical conditions
Solution Approach 1:
The invention extracts the essential testing functions from the centralized laboratory environment and places them in a portable device that can be used at the point of birth. The handheld device contains integrated reagents, detection components, and processing capabilities that were previously available only in laboratories, enabling immediate testing without mailing specimens.
Solution Approach 2:
The portable device serves as an intermediary between sample collection and final diagnosis. It includes an integrated sample processing chamber that receives blood samples directly from collection devices, performs automated processing, and interfaces with a display or communication system to transmit results, eliminating the need for intermediate mailing and laboratory handling steps.
2Adaptability or versatility
If mass spectrometry and laboratory technologies are used for high-throughput newborn screening, then multiplexed testing for over 30 conditions is achieved, but significant liquid handling and specialized technicians are required
Solution Approach 1:
The invention merges multiple testing functions into a single integrated handheld device. The device combines sample reception, automated liquid handling, multiple assay chambers for different analytes, detection systems, and result processing all in one portable unit, eliminating the need for separate laboratory equipment and technician operations for each test type.
Solution Approach 2:
The device incorporates automated sample processing capabilities that perform liquid handling, reagent mixing, and assay execution without requiring specialized technician intervention. The integrated system automatically manages the entire testing workflow from sample insertion to result generation, making complex multiplexed testing accessible to non-specialists.
3Reliability
If dried blood spot specimens are mailed to public health laboratories for processing, then standardized newborn screening is performed, but delays of a few days occur before diagnosis
Solution Approach 1:
The invention segments the centralized laboratory screening process into distributed point-of-care testing units. Each handheld device is a self-contained testing station that can independently perform standardized screening without relying on centralized laboratory infrastructure, enabling immediate local processing while maintaining quality through integrated automated protocols.

AI summary
A point-of-birth system and instrument, biochemical cartridge, and methods for newborn screening is disclosed. Namely, a point-of-birth system is provided that includes a point-of-birth instrument for receiving and processing a biochemical cartridge for performing newborn screening. Further, a portable smart device, such as a smartphone or tablet, is in communication with point-of-birth instrument, wherein the smart device may include a newborn screening (NBS) mobile app. In one example, the point-of-birth system and point-of-birth instrument support newborn biological screening only. However, in another example, the point-of-birth system and point-of-birth instrument support both newborn biological screening and newborn physiological screening.
