This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,320.

Summary of the Inventive Concept

The present inventive concept discloses a family of blood sequestration devices adapted for specific, narrow markets or unique operational environments, including high-security facilities, disaster relief scenarios, remote areas with limited medical resources, extreme cold environments, and high-altitude environments.

Background and Problem Solved

The original blood sequestration device and method, as described in the original patent, provides an effective solution for accessing the bloodstream of a patient and inhibiting potentially contaminated blood from inclusion in a blood culture test sample. However, the original device may not be suitable for use in specialized environments, such as high-security facilities, disaster relief scenarios, or extreme weather conditions, where additional security features, ruggedization, or adaptability to unique conditions are required.

Detailed Description of the Inventive Concept

The newly generated claims describe a system for collecting blood samples in high-security facilities, comprising a blood sequestration device with enhanced security features to prevent unauthorized access to the blood sample. Another embodiment includes a method for disaster relief blood sampling, wherein the blood sequestration device is adapted for use in extreme weather conditions and includes a water-resistant housing. Additionally, the inventive concept encompasses a blood sequestration device for use in remote areas with limited medical resources, comprising a simplified user interface and a compact design for easy transportation. Other variations include a system for collecting blood samples in extreme cold environments, wherein the blood sequestration device includes a thermal insulation component to maintain a stable temperature during sample collection, and a blood sequestration device for use in high-altitude environments, comprising a pressure-resistant housing and a modified needle design to accommodate changes in atmospheric pressure.

Novelty and Inventive Step

The inventive concept's novelty lies in its adaptation of the original blood sequestration device to address the specific challenges and requirements of unique operational environments. The inventive step is the recognition of the need for specialized variations of the original device and the development of targeted solutions to meet those needs.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include blood sequestration devices adapted for use in other specialized environments, such as space exploration, military operations, or high-containment laboratories. Variations could also include different materials, designs, or user interfaces tailored to specific market needs.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including healthcare, biotechnology, and pharmaceuticals. The specialized blood sequestration devices could be marketed to high-security facilities, disaster relief organizations, remote medical clinics, and research institutions operating in extreme environments.

Field of Art

Medical device engineering, specifically blood collection and sampling technologies, focusing on needle-based sequestration devices for clinical diagnostics

Person of Ordinary Skill (PHOSITA) Profile

A biomedical engineer or medical device designer with expertise in blood collection technologies, familiar with safety mechanisms, sample isolation techniques, and environmental adaptation of medical instrumentation

Obviousness Rationale

A person having ordinary skill would recognize that the fundamental blood sequestration mechanism can be readily adapted to different environmental contexts by applying standard engineering design principles. The core needle retraction and sample isolation technology from the source patent provides a predictable base for specialized variations addressing specific operational challenges. These adaptations represent routine engineering modifications that would be apparent to a skilled practitioner seeking to optimize the device for unique use cases.
