Method and apparatus for penetrating tissue
View Patent ↗These and other objects of the present invention are achieved in a body fluid sampling system for use on a tissue site that includes an electrically powered drive force generator. A penetrating member is operatively coupled to the force generator. The force generator moves the member along a path out of a housing having a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A cartridge houses the penetrating member. The cartridge has first and second seals coupled to the penetrating member to maintain a sterile environment around a portion of the penetration member prior to penetrating member actuation. A user interface is configured to relay at least one of, penetrating member performance or a penetrating member setting.
1. A body fluid sampling system for use on a tissue site, the system comprising:
a drive force generator;
a penetrating member operatively coupled to said force generator, said force generator moving said member along a path out of a housing having a penetrating member exit, into said tissue site, stopping in said tissue site, and withdrawing out of said tissue site;
said drive force generator configured to be controlled to follow a predetermined velocity trajectory into the tissue and out of said tissue;
a disposable housing said penetrating member, said disposable having a first and a second seal formed at a distal end and a proximal end of said disposable respectively to maintain a sterile environment around a portion of the penetration member prior to penetrating member actuation; and
a user interface coupled to a processor, wherein in response to an input at the user interface by a user the processor provides an input to the drive force generator of a lancing penetration parameter selected from at least one of, penetrating member depth of penetration, velocity, braking, or retraction.
2. A body fluid sampling system for use on a tissue site, the system comprising:
a drive force generator;
a penetrating member operatively coupled to said force generator, said force generator moving said member along a path out of a housing having a penetrating member exit, into said tissue site, stopping in said tissue site, and withdrawing out of said tissue site;
a position sensor positioned to provide an indication of a position of the penetrating member during actuation;
a disposable housing said penetrating member, said disposable having a first and a second seal formed at a distal end and a proximal end of said disposable respectively to maintain a sterile environment around a portion of the penetration member prior to penetrating member actuation; and
a user interface coupled to a processor, wherein in response to an input at the user interface by a user the processor provides an input to the drive force generator of a lancing penetration parameter selected from at least one of, penetrating member depth of penetration, velocity, braking, or retraction.
