Recording device for recording a blood count parameter

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

This invention concerns a device and method for accurately and non-invasively measuring blood count parameters—such as glucose concentration—inside a blood vessel. The system uses multiple transmitting and receiving antennas to send microwave signals through tissues. By selecting the antenna configuration with the least signal loss, the device ensures optimal signal transmission into the targeted vein, enabling more precise acquisition of blood characteristics compared to previous non-invasive methods. The invention can be integrated into wearable items like an armband for continuous monitoring.

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

• Continuous, non-invasive blood glucose monitoring for diabetic patients
• General monitoring of key blood parameters (e.g., glucose, lactate, oxygen) in hospitals or home-care settings
• Integration into wearable health devices for long-term patient tracking
• Remote or ambulatory patient monitoring for critical blood parameters
• Data-driven feedback for medication dosing (e.g., insulin) through live monitoring
• Clinical studies requiring accurate, passive blood parameter tracking without recurring invasive blood draws

BenefitsContent extracted from patent full text and abstract with AI.

• Eliminates the need for blood draws, reducing discomfort and infection risk for patients
• Enables continuous and real-time monitoring, which can improve diagnosis and treatment response (e.g., in diabetes management)
• Offers more accurate measurements by directly targeting venous blood, overcoming the lag and inaccuracy of non-venous or surface capillary readings
• Reduces user error and inconvenience associated with test strips and finger-prick methods
• Improves patient compliance with long-term monitoring regimens by being non-intrusive and wearable
• Facilitates early detection of rapid physiological changes, allowing timely medical intervention

Patent Abstract

The device has a processor (109) for selecting a detection configuration comprising a transmit antenna and a receiving antenna. A loss detector (107) detects a loss value based on a transmit signal and a receive signal when another detection configuration is selected to transmit the transmit signal. The detector detects another loss value based on the transmit signal and the receive signal when the former detection configuration is selected to transmit the transmit signal. The processor selects the detection configuration having a lower loss value to detect a blood count parameter. An independent claim is also included for a method for detecting a blood count parameter in a blood vessel.
