Filed:

Apr 23, 2002

Appl. No.:

10/128780

Inventors:

Brent G. Duchon - San Jose CA, US
Joel S. Douglas - Los Altos Hills CA, US
Jeffrey N. Roe - San Ramon CA, US
Ryszard Radwanski - Morgan Hill CA, US

Assignee:

Amira Medical - Palo Alto CA

International Classification:

A61B 5/00

US Classification:

600583, 600584, 606181

Abstract:

A device for sampling body fluid includes a housing having a sleeve at a forward end thereof which is displaceable in response to being pressed against a user's skin to trigger the firing of a lancet. After the lancet is removed from the incision, the sleeve is repeatedly pressed against the skin to depress a ring of body tissue in surrounding relationship to the incision to express body fluid outwardly through the incision. A pusher member is then actuated to push a capillary tube through a front end of the housing for drawing-in body fluid. The lancet is a disposable lancet which includes a body supporting a skin-lancing member and the capillary tube. The disposable lancet passes through an upper end of a lancet carrier when being installed or removed. The device cannot be armed until the disposable lancet is installed in the housing, because the capillary tube functions to push a safety device to a non-safety position.

Assignee:

Mercury Diagnostics, Incorporated - Scotts Valley CA

International Classification:

A61B 508

US Classification:

702 31

Abstract:

A monitoring system which collects patient physiological date is designed specifically for communication with a communication module which facilitates data transfer from the monitoring system to a remote site. The communication module has data input mechanisms to facilitate setting parameters of the monitoring system and/or the communication module. The communication module is provided with a modem member which is used to communicate with the remote site and an optional data exchange module which is designed to communicate the same information with a local computer system. The remote site may be a bulletin board system or internet site where the monitoring information can be stored by the patient using the monitoring system by patient identification or name and include monitoring readings, time and date stamp, conditions such as meal times, exercise times and therapy amounts and their associated date and time.
