Recording device for recording a blood count parameter

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent discloses a device and method for non-invasively measuring blood parameters (such as glucose level) directly within a blood vessel by transmitting electromagnetic signals (at different frequencies) into the vessel, capturing the received signals, and analyzing frequency shifts in the absorption spectrum. The device includes a transmitter, receiver, loss detector, and processor that collectively determine blood composition parameters based on the frequency shifts correlated to reference values. The system can be implemented, for example, in a wearable wristband.

Use CasesContent extracted from patent full text and abstract with AI.

• Non-invasive and continuous monitoring of blood glucose levels for diabetic patients
• Monitoring lactate, lactic acid, or oxygen content in the bloodstream for critical care or sports medicine applications
• Telemedicine applications for remote patient health tracking
• Wearable health trackers incorporated into armbands or wristbands for daily health management
• Hospital or clinical settings for rapid, painless blood analysis without drawing blood samples

BenefitsContent extracted from patent full text and abstract with AI.

• Non-invasive: No need for blood draws or finger pricks, increasing patient comfort and compliance
• Continuous and real-time monitoring: Enables better management of conditions like diabetes and provides timely alerts for dangerous fluctuations
• High accuracy: The method focuses on venous blood and leverages frequency shifts in absorption lines, improving reliability compared to surface measurements
• Adaptable to various blood constituents: Not limited to glucose, but can be configured for other blood parameters (e.g., lactate, oxygen)
• Wearable and user-friendly: Can be integrated into comfortable devices like wristbands, potentially supporting remote healthcare and reducing hospital visits
• Robust against individual variability and skin properties, as it targets blood parameters in vessels rather than superficial skin readings

Patent Abstract

A transmitter (101) transmits transmit signals of corresponding frequencies into blood vessel. A receiver (105) receives the transmitted signals. A loss detector (107) determines loss values based on transmitting and receiving signals. A processor (109) determines frequency shifts of loss values relative to reference loss values and determines blood count parameter based on frequency shifts. An independent claim is included for method for detecting blood count parameter in blood vessel.
