US Patent:

8386042, Feb 26, 2013

Filed:

Nov 3, 2009

Appl. No.:

12/611341

Inventors:

Dmitry Yudovsky - Campbell CA, US
Ian B. Hanson - Northridge CA, US
Sheldon B. Moberg - Thousand Oaks CA, US

Assignee:

Medtronic Minimed, Inc. - Northridge CA

International Classification:

A61N 1/00

US Classification:

607 19, 600595, 7351434

Abstract:

A portable medical device is provided with an internal accelerometer device. The medical device includes a circuit board, the accelerometer device, and a response module coupled to the accelerometer device. The accelerometer device is mechanically and electrically coupled to the circuit board, and it includes a plurality of mass-supporting arms for a plurality of electrically distinct sensor electrodes, piezoelectric material for the mass-supporting arm, and a proof mass supported by the mass-supporting arms. Each of the mass-supporting arms has one of the sensor electrodes located thereon. Acceleration of the proof mass causes deflection of the piezoelectric material, which generates respective sensor signals at one or more of the sensor electrodes. The response module is configured to initiate an acceleration-dependent operation of the portable medical device in response to generated sensor signals present at the sensor electrodes.

International Classification:

A61M 5/172
A61M 5/145

Abstract:

A drive mechanism having integrated status indication includes a drive housing, a status switch interconnect, a drive biasing member, a piston, and a drug container having a cap, a pierceable seal, a barrel, and a plunger seal, wherein the drive biasing member is configured to bear upon an interface surface of the piston. Drive mechanism may include an incremental status stem having a stem interconnect, wherein the stem resides within the drive housing and the piston, and wherein the stem has an interconnect which engages one or more contacts on the piston to provide incremental feedback. A drug delivery pump with integrated status indication includes a housing and an assembly platform, upon which an activation mechanism, an insertion mechanism, a fluid pathway connection, a power and control system, and the drive mechanism having a drug container may be mounted.
