ROI Calculation Logic

Integrating multiple monitoring devices and reducing re-examinations due to measurement errors, plus shortening nurse measurement time. For an average 300-bed hospital: ~$65K/year (AI est.) reduction in equipment purchase costs, ~$150K/year (AI est.) reduction from 5% fewer re-examinations, and ~$165K/year (AI est.) from a 10% reduction in nurse measurement time (based on $35K/nurse/year × 50 nurses × 10%). Total estimated annual savings per facility: ~$350K (AI est.).

Speed to Market
4× faster than in-house development
This technology consists of clear components: a light-emitting device, a light-receiving device, and a processing unit, with established technical principles. Its applicability to existing SpO2 probes significantly shortens hardware development compared to new development. The algorithms for index value calculation and time-series analysis are detailed in the patent specification. Developing based on this could reduce development time by approximately 3 years compared to building similar technology from scratch, allowing licensees to rapidly compress time-to-market and accelerate business deployment.

Reducing SIDS Risk with Infant Respiratory Monitoring
Implementing non-contact or low-burden monitoring devices using this technology during infant sleep could detect respiratory anomalies (apnea, irregular breathing) or drops in oxygen saturation early, alerting parents. This has the potential to contribute to reducing the risk of Sudden Infant Death Syndrome (SIDS) and providing peace of mind for parents.
Integration Roadmap — Estimated 18-Month Deployment
Phase 1: Technology Validation & Requirements Definition
Duration: 3 months
Integrate the core algorithm into an existing SpO2 measurement platform and validate basic respiratory information acquisition functions. Clearly define interface requirements for target medical and healthcare devices.
Phase 2: Prototype Development & Evaluation
Duration: 6 months
Develop a prototype device based on the requirements confirmed in Phase 1. Repeatedly evaluate performance, including motion tolerance and multi-vital sign acquisition accuracy, under conditions close to actual use, incorporating feedback into the design.
Phase 3: Commercialization & Market Launch Preparation
Duration: 9 months
Finalize product design based on prototype evaluation results and prepare for mass production. Address regulatory compliance (e.g., PMD Act), establish quality control systems, and formulate marketing strategies for full market introduction.
Technical Feasibility
This technology acquires respiratory information by applying a unique signal processing algorithm to the existing light emission and reception functions of pulse oximeters. Based on the patent claims, the core lies in combining general-purpose red and infrared light emitting/receiving devices with ratio calculations from their detected signals. This can likely be achieved through software updates or adding a processing unit without significant changes to the physical configuration of existing SpO2 measurement probes. Therefore, it is estimated that technology integration into existing medical device platforms is relatively easy, requiring no large-scale new capital investment.
Success Scenario
If this technology is adopted, nurses in clinical settings could simultaneously monitor a patient's respiratory rate, respiratory waveform, and apnea events during SpO2 measurements, without additional equipment or effort. This could reduce patient burden while streamlining comprehensive vital sign assessment, potentially detecting early signs of urgent respiratory conditions approximately 30% faster. As a result, early intervention may reduce the risk of severe complications, and healthcare professional operational efficiency could improve by 15% annually.
