Wearable Glucose Monitoring Device Improvements

A patch for attaching a glucose monitor to a user's skin for at least 10 days without irritation. The patch has a closed ring shape that fits around the monitor. It has a water-resistant, hypoallergenic adhesive layer to adhere to the skin. A peelable protective sheet covers the adhesive to prevent premature sticking. This allows the patch to be positioned accurately around the monitor without adhering to anything else. The long-lasting adhesive provides secure retention for a week or more.

Extending the life of adhesive patches on wearable medical devices like continuous glucose monitors (CGMs) to prevent premature detachment due to skin perspiration, water exposure, and other factors. The method involves applying a thin film of a moisture-absorbing material over the original adhesive patch without covering the sensor itself. This additional layer absorbs moisture and prevents it from deteriorating the adhesive, extending the patch's life. The moisture-absorbing film is thin and transparent, so it doesn't affect the sensor's performance or appearance.

A patch for reinforcing adhesion of a continuous glucose monitoring device on the skin. The patch has an overlay with a removable release paper. When applied, the overlay pressurizes the device's existing adhesive tape against the skin for stronger attachment. The removable release paper allows easy separation without contaminating the device's adhesive. The paper is cut into multiple pieces that can be independently removed. This allows precise positioning of the overlay without moving the device.

Method for transmitting and receiving biometric information between a continuous blood glucose monitoring sensor and a communication terminal. The method involves generating transmission packets with a sequential generation identifier when the sensor measures biometric data like glucose. The packets are transmitted to the terminal which checks the identifiers to find and request any missing packets. This allows reliable reception even if there are disconnections.

In vivo analyte monitoring system with improved sensor insertion device to reduce the likelihood of improper sensor insertion and damage. The system has a sensor control device with an electronics housing, a sensor inside, and a sharp protruding from the bottom. A removable sensor cap covers the bottom and contains the sensor tail and sharp. The cap has a sealed chamber. The sharp is inserted through the cap and housing into the skin. The cap prevents premature retraction and stabilizes the sharp during insertion. It also prevents blood from fouling the sensor. The cap can be motion-actuated to delay retraction until the user removes it. This reduces the likelihood of prematurely withdrawing the sharp during insertion. The cap also reduces the axial and rotational movement of components during insertion. The cap can be designed for dermal sensors with smaller scales and shallower insertion paths.

Continuous, minimally invasive glucose monitoring system for diabetics that avoids needing to prick the skin to take blood samples. The system uses a body-attachable sensor module that can be inserted into the skin using an applicator. When attached to the body, the user presses a button on the applicator to initiate the sensor's operation. This allows precise insertion depth and timing. The sensor has a PCB, sensor probe, and pressure module.

Continuous glucose monitoring system with improved usability that allows users to easily attach the sensor to their skin. The system has an applicator that protrudes the sensor needle into the body when pressed. This eliminates the need for users to manually insert the sensor. After insertion, the applicator also extracts the needle.

Flexible, adhesive patch for long-term monitoring of bodily fluids like glucose. The patch has a thin, flexible circuit board with sensors and electronics, protected by layers. It adheres to the skin using a stronger adhesive than the removable applicator. The patch can be applied using an insertion tool. This allows inserting sensors into tissue. The tool then removes the patch on the skin. The tool can also press contacts onto the circuit. The patch can transmit data wirelessly. The thin, flexible design allows comfortable long-term wear. The patch can be manufactured using roll-to-roll printing techniques.

A body attachable unit for continuous glucose monitoring that can be inserted and attached to the skin using an applicator. The attachable unit contains the glucose sensor, electronics, and communication components. The user inserts the sensor into their skin through the applicator. After attachment, the user manually makes contact between the sensor and PCB to initiate operation. This allows precise sensor insertion timing, avoids contamination, and improves accuracy compared to pre-assembled sensors.

Flexible body-mountable devices with sensors that can be worn on the skin to continuously monitor analytes like glucose in interstitial fluid. The devices have flexible substrates that adhere to the skin and extend probes beneath it to access the fluid. The probes contain sensors to measure analyte concentrations. The devices also have electronics, batteries, and antennas all on a flexible substrate. This allows long-term wearability and wireless communication. The flexible form factor reduces discomfort and enables unobtrusive monitoring.

A medical sensor assembly for long-term wear on the skin to continuously monitor physiological parameters like glucose levels. The assembly has a flexible adhesive patch attached to the skin and a sensor inserted into it. The sensor has a measuring part that goes into the skin and a contact part to connect to a monitoring device. The patch has a flap that folds up to provide an opening for the sensor to pass through. This allows the sensor to be inserted into the skin without needing a separate entry point. The flap is permanently attached to the sensor to keep it in place.
