Abstract

Fluid infusion systems such as a portable fluid infusion device includes a housing configured to accommodate a removable fluid reservoir. The housing has a largest dimension and a smallest dimension. The portable fluid infusion device includes a drive system configured to be serially coupled to the removable fluid reservoir such that a combined dimension of the drive system and the removable fluid reservoir is less than or equal to the largest dimension. The portable fluid infusion device includes a planar battery configured to supply power to the drive system. The planar battery has a plurality of faces comprising one or more faces having a largest area, and the planar battery being situated such that the one or more faces are parallel to the largest dimension and the smallest dimension.

First claim

What is claimed is:

1. A portable fluid infusion device comprising:
a housing configured to accommodate a removable fluid reservoir;
a drive system within the housing and configured to dispense fluid from the removable fluid reservoir;
a battery within the housing and configured to supply power to the drive system;
a button on the housing;
a light emitting element, disposed within the button, wherein the light emitting element is configured to provide a visual indicator, that is viewable outside the housing and through the button, of a status associated with the portable fluid infusion device; and
processing circuitry configured to:
generate a first set of data of the portable fluid infusion device, wherein the first set of data includes the status associated with the portable fluid infusion device that is visually indicated by the light emitting element, and wherein the first set of data includes data indicating one or more of: whether the portable fluid infusion device is on, whether the portable fluid infusion device is operating properly, whether the portable fluid infusion device is undergoing wireless charging or done with wireless charging, whether there is an alarm or alert associated with the portable fluid infusion device, or whether the portable fluid infusion device is in pairing mode; and
generate a second set of data of the portable fluid infusion device, wherein the second set of data includes all data of the portable fluid infusion device that is to be displayed to a user, and wherein at least a portion of the second set of data of the portable fluid infusion device is for displaying on a device other than the portable fluid infusion device, and

wherein no portion of the portable fluid infusion device includes a display.

2. The portable fluid infusion device of claim 1 , further comprising a vibration motor.

3. The portable fluid infusion device of claim 1 , wherein the battery has a flat rectangular shape.

4. The portable fluid infusion device of claim 1 , wherein the battery has a flat cylindrical shape.

5. The portable fluid infusion device of claim 1 , further comprising a force sensor situated between the drive system and the housing.

6. The portable fluid infusion device of claim 1 , wherein the housing comprises a plurality of housing portions.

7. The portable fluid infusion device of claim 1 , wherein the portable fluid infusion device is an insulin infusion device.

8. The portable fluid infusion device of claim 1 , wherein the drive system comprises at least a motor and a slide, wherein in a retracted position, the motor is at least partially within the slide, wherein forward advancement of the slide causes the removable fluid reservoir to dispense fluid, and wherein each of the motor, slide, and the removable fluid reservoir are configured to be serially coupled to one another and be inline with one another to have a combined dimension that is less than or equal to the largest dimension.

9. The portable fluid infusion device of claim 1 , wherein the second set of data of the portable fluid infusion device includes an amount of insulin delivered.

10. The portable fluid infusion device of claim 1 , wherein the housing has a largest dimension, and wherein the drive system is configured to be serially coupled to the removable fluid reservoir such that a combined dimension of the drive system and the removable fluid reservoir is less than or equal to the largest dimension.

11. The portable fluid infusion device of claim 10 , wherein the housing has a smallest dimension, wherein the battery has a plurality of faces comprising one or more faces having a largest area, and wherein the battery is situated such that the one or more faces are parallel to the largest dimension and the smallest dimension.
