Tissue penetration device
View Patent ↗A moving coil tissue penetration device includes a magnetic source that produces a magnetic field in a magnetically active region. A cylindrical coil is secured to a translation substrate and disposed at least partially within the magnetically active region. A sharpened member is configured to penetrate tissue and mechanically coupled to the translation substrate.
1. A lancing system comprising
a controllable driver that includes a driver coil pack, the controllable driver having a proximal end and a distal end with a distal end of a coupler shaft disposed at the distal end of the controllable driver;
a ratchet drive mechanism operably disposed at the distal end of the controllable driver; and
a plurality of lancets configured to be sequentially advanced by the ratchet drive mechanism into a coupled configuration with the coupler shaft of the controllable driver, each of a lancet being configured to be coupled to the controllable driver to be advanced from a housing to penetrating a skin surface and create an aperture from which a body fluid flows to an interior of the housing that includes a plurality of sample chambers.
2. The system of claim 1 , wherein the plurality of lancets are disposed within a lancet belt.
3. The system of claim 2 , wherein the lancet belt is disposed within a lancet belt cartridge having a supply canister for storage of the unused lancets of the lancet belt and a receptacle canister for acceptance and storage of the used lancets of the lancet belt.
4. The system of claim 1 , wherein the plurality of lancets are disposed within a lancet module belt.
5. The system of claim 4 , wherein the lancet module belt is disposed within a lancet module cartridge having supply canister for the unused lancet modules and a receptacle canister for acceptance and storage of used lancet modules.
6. The system of claim 1 , wherein the plurality of lancets are disposed within a sampling module belt comprising a plurality of sampling modules interconnected by a flexible belt member.
7. The system of claim 6 , wherein the sampling module belt is disposed within a sampling module cartridge having supply canister for the unused sampling modules and a receptacle canister for acceptance and storage of used sampling modules.
8. The system of claim 1 , wherein the plurality of lancets further comprise a drive head secured to a proximal end of each lancet and configured to be engaged by a drive coupler secured to a distal end of the coupler shaft.
9. The system of claim 8 , wherein the drive heads are substantially cylindrical in shape and the drive coupler comprises a T-slot drive coupler.
10. A lancing system comprising
a controllable driver having a proximal end and a distal end with a distal end of a coupler shaft disposed at the distal end of the controllable driver;
a ratchet drive mechanism operably disposed at the distal end of the controllable driver; and
a plurality of lancets configured to be sequentially advanced by the ratchet drive mechanism into a coupled configuration with the coupler shaft of the controllable driver, the plurality of lancets are disposed within a sampling module belt comprising a plurality of sampling modules interconnected by a flexible belt member, and
wherein the sampling modules of the sampling module belt further comprise an analytical site and sensor contacts and the ratchet drive mechanism further comprises a reader module with contact brushes configured to make electrical contact with the sensor contacts.
11. A lancing system comprising
a controllable driver having a proximal end and a distal end with a distal end of a coupler shaft disposed at the distal end of the controllable driver;
a ratchet drive mechanism operably disposed at the distal end of the controllable driver; and
a plurality of lancets configured to be sequentially advanced by the ratchet drive mechanism into a coupled configuration with the coupler shaft of the controllable driver; the plurality of lancets being disposed within a lancet belt having a supply canister for storage of the unused lancets of the lancet belt and a receptacle canister for acceptance and storage of the used lancets of the lancet belt, and;
wherein the ratchet drive mechanism comprises:
lancet guide wheel configured to laterally advance a lancet to be used into a coupled arrangement with a drive coupler disposed on a distal end of the elongate coupler shaft;
first and second cog rollers configured to pull tension on a first and second belt tape of the lancet belt and separate the first and second belt tapes away from the lancet to be used; and
an actuation lever mechanically coupled to the lancet guide wheel and first and second cog rollers and configured to advance the lancet guide wheel and first and second cog rollers in a synchronized manner so that as a lancet to be used is freed from the first and second belt tapes the freed lancet is then picked up and advanced into the drive coupler by the lancet guide wheel.
12. The system of claim 11 , further comprising a first and second take-up roller configured to take up slack portions of the first and second belt tapes.
