Body fluid sampling module with a continuous compression tissue interface surface
A body fluid sampling device includes a housing, a penetrating member positioned in the housing and a test strip. A compliant front end is coupled to the housing. The compliant front-end includes a rigid member with an interior aperture to receive the body fluid from a wound site.
1. A body fluid sampling device, comprising:
a housing;
a penetrating member positioned in the housing coupled to an electronic controllable penetrating member driver;
a position sensor;
a processor in communication with the position sensor, the processor processing information regarding skin site position for lancing and success rate of a lancing event relative to different skin sites, in response to selection of a profile the processor configured to modulate power from a power supply to the electronic controllable penetrating member driver, an electrical conductor electrically coupling the processor to the position sensor;
a database that stores information and statistics for each user and each profile of a particular user, the processor configured to store results of a lancing event and construct the database; and
a display coupled to the processor and the database that displays information to teach a user skin sites to avoid and use for successful lancing to obtain a good sample of fluid sample during a lancing event.
2. The device of claim 1 , wherein the database is updated based on measurements achieved from previous failed and successful measurements of the body fluid.
3. The device of claim 2 , wherein multiple targets can be displayed for different skin sites.
4. A body fluid sampling device, comprising:
a housing;
a penetrating member positioned in the housing coupled to an electronic controllable penetrating member driver;
a position sensor;
a processor that includes historical penetration data of a user's different skin sites, in response to selection of a profile the processor configured to modulate power from the electronic controllable penetrating member driver, an electrical conductor electrically coupling the processor to the position sensor;
a database that stores information and statistics for each user and each profile of a particular user, the processor configured to store results of a lancing event and construct the database; and
a display coupled to the processor that displays a skin site position in response to a measured value as a skin site approaches the position sensor, wherein previous failed and successful measurement attempts are plotted with position corresponding to the measured value, the display coupled to the processor and the database and displaying information to teach a user skin sites to avoid and use for successful lancing to obtain a good sample of fluid sample during a lancing event.
5. The device of claim 4 , wherein the display instructs a user to position a finger position in a region with a highest number of successful historical measurements.
6. The device of claim 5 , wherein the processor filters the historical data based on skin site location.
