Summary of the Inventive Concept

A system and method for preventing pressure injuries in patients in high-security, disaster relief, extreme weather, remote, or immunocompromised environments, utilizing specialized sensors, processors, and communication devices tailored to each environment's unique challenges.

Background and Problem Solved

The original patent, 'Pressure injury prevention sensor and decision support tool', addresses the pressing issue of pressure ulcers in general healthcare settings. However, it does not provide specific solutions for patients in high-security, disaster relief, extreme weather, remote, or immunocompromised environments, where the risk of pressure injuries is heightened and conventional solutions may not be applicable. The new inventive concept fills this gap by adapting the pressure injury prevention system to these specialized environments.

Detailed Description of the Inventive Concept

The new inventive concept comprises a system and method for preventing pressure injuries in patients in high-security, disaster relief, extreme weather, remote, or immunocompromised environments. The system includes a tamper-evident measurement device with sensors to measure pressure from the patient's weight, a secure processor to encrypt patient data, and a satellite communication device for alerting caregivers in disaster relief settings. The system can also include a waterproof measurement device for extreme weather conditions, a remote monitoring center for transmitting patient pressure data in remote or rural areas, and a processor configured to analyze patient data in conjunction with immunological data for patients with compromised immune systems.

Novelty and Inventive Step

The new claims introduce novel and non-obvious adaptations of the original pressure injury prevention system to specialized environments, including high-security, disaster relief, extreme weather, remote, and immunocompromised environments. The inventive step lies in the integration of environment-specific components and features, such as tamper-evident measurement devices, secure processors, satellite communication devices, waterproof measurement devices, and immunological data analysis, which enable the system to effectively prevent pressure injuries in these unique settings.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different types of sensors, such as capacitive or piezoelectric sensors, or integrating the system with existing healthcare infrastructure, such as electronic health records or patient monitoring systems. Variations of the system could also be designed for specific industries, such as aerospace or maritime, where patients may be exposed to extreme environments.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including healthcare, disaster relief, aerospace, and maritime. The system could be marketed to healthcare providers, disaster relief organizations, and companies operating in extreme environments, offering a unique solution for preventing pressure injuries in specialized settings.
