Blood glucose meter

A portable handheld medical diagnostic device includes a front housing and a rear housing opposite the front housing. The front housing and the rear housing form a protective enclosure. A main circuit board is located in the protective enclosure. The main circuit board includes a controller facilitating a physiologic measurement. A display device is connected to the main circuit board that displays information related to the physiologic measurement. A frame is located in the protective enclosure that carries the display device and locates the display device adjacent the front housing such that the display device can be viewed from outside the protective enclosure. The frame includes a strip port formed integrally therewith that is accessible from outside the protective enclosure.

A limited-use blood glucose meter includes a printed circuit board assembly that includes a power source, a strip port, a strip reading device, a controller device, a bi-stable display, and a display controller. The strip reading measures a reaction between a blood sample present on the blood glucose test strip and the blood glucose reagent, generates a blood glucose signal, and calculates a blood glucose level. The controller device receives the blood glucose level from the strip reading device. The controller device provides display instructions to the display controller and the display controller provides drive voltages to the bi-stable segments such that the bi-stable segments persistently display the most-recent blood glucose level. The strip reading device performs a predetermined number of blood glucose tests and calculates a blood glucose level only for blood glucose strips associated with the disposable blood glucose meter.

A portable handheld medical diagnostic device includes a housing forming a protective enclosure. A main circuit board is located in the protective enclosure. The main circuit board includes a controller facilitating a physiologic measurement. A display device is connected to the main circuit board that displays information related to the physiologic measurement. An electronic skin is on the housing. The electronic skin comprises a liquid crystal material and is configured to display a color.

A control circuit and method for controlling a bi-stable display having bi-stable segments each capable of transitioning between an on state and an off state via application of a voltage are disclosed. The voltage is provided to a display driver from a charge pump, and supplied to individual ones of the bi-stable segments via outputs from the display driver in accordance with display instructions provided by a system controller. Both a bi-stable segment voltage level of at least one of the outputs of the display driver and a charge pump voltage level of the voltage are detected and compared to a valid bi-stable segment voltage level and a valid charge pump voltage level, respectively. A malfunction signal may be provided to the system controller if either of the detected voltage levels is not valid. The control circuit is useful in an electronic device such as, for example, a blood glucose measuring device.

Bi-stable display fail safes and devices incorporating the same

An instrument ( ) has a well ( ) for receiving a dry cell ( ), an opening ( ) through which a first connector ( ) is exposed to the well ( ), and a boss ( ) adjacent the opening ( ). The boss ( ) precludes the wrong terminal of the dry cell ( ) from engaging the first connector ( ) when the dry cell ( ) is inserted into the well ( ) in incorrect orientation. A second connector ( ) includes a base ( ), a first leg ( ) resiliently connected to and extending away from the base portion, a second leg ( ) resiliently connected to and extending away from the first leg ( ), and a third leg ( ) resiliently connected to and extending away from the second leg ( ) and toward the first leg ( ). A display ( ) for the instrument ( ) has a lens ( ) having a substantially transparent substrate with a polyurethane coating. The instrument housing has first and second portions. At least one locator pin ( ) extends from one ( ) of the housing portions and at least one complementary socket ( ) extends from the other ( ) of the housing portions for receiving the pin ( ) to maintain the first ( ) and second ( ) portions in assembled orientation.
