Enhanced Blood Sequestration Device with Integrated Sensors and Real-Time Quality Control
Legal Citation
Summary of the Inventive Concept
An improved blood sequestration device that incorporates advanced sensors and data analytics to ensure high-quality blood samples, reducing contamination risks and improving diagnostic accuracy.
Background and Problem Solved
The original patent disclosed a blood sequestration device that addressed the need for safe and efficient blood sampling. However, it lacked real-time monitoring and quality control features, which can lead to contaminated samples and inaccurate diagnoses. The new inventive concept addresses this limitation by integrating blood flow sensors, sterilization modules, and data analytics to provide real-time feedback and quality control during blood sampling.
Detailed Description of the Inventive Concept
The enhanced blood sequestration device comprises a housing, a movable element, and a blood flow sensor that detects changes in blood flow and alerts the user to potential contamination. The device also features a sterilization module to ensure the needle and sampling pathway are sterile. A data analytics module analyzes blood flow patterns and provides real-time feedback to the user. The device can automatically retract the needle and seal the blood sample container upon detection of potential contamination. Additionally, the device features a dynamic needle retraction system that adjusts the rate of needle retraction based on blood flow rate and pressure, reducing the risk of contamination and improving sample quality.
Novelty and Inventive Step
The new claims introduce the integration of advanced sensors and data analytics, which enable real-time quality control and contamination detection. The dynamic needle retraction system and sterilization module further enhance the device's ability to provide high-quality blood samples. These features are not present in the original patent and provide a significant improvement over existing blood sequestration devices.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include the use of different types of sensors, such as pressure sensors or temperature sensors, to detect changes in blood flow. The device could also be designed for use with different types of needles or sampling pathways. Additionally, the data analytics module could be integrated with electronic health records or laboratory information systems to provide a more comprehensive view of blood sample quality and diagnostic results.
Potential Commercial Applications and Market
The enhanced blood sequestration device has significant commercial potential in the medical device industry, particularly in the areas of infectious disease diagnosis and blood banking. The device's ability to provide high-quality blood samples and reduce contamination risks could lead to improved diagnostic accuracy and patient outcomes. The market for blood sequestration devices is growing, driven by the increasing demand for accurate and efficient blood sampling technologies.
