Battery pack assembly having a status indicator for use during mechanical ventilation
First Claim
1. A method for maintaining charge to a ventilation system using more than one battery pack assemblies, the method comprising:
- receiving a first cell status for a first battery pack assembly, wherein the first cell status for the first battery pack assembly is displayed on a first status indicator on an exposed exterior of the first battery pack assembly, and wherein the first cell status indicates information about the first battery pack assembly;
detecting low voltage information in the first cell status;
disconnecting the ventilation system from the first battery pack assembly;
connecting the ventilation system to a second battery pack assembly; and
displaying a second cell status for the second battery pack assembly on a second status indicator, wherein the second cell status indicates information about the second battery pack assembly, and wherein the second cell status indicates different battery information than the first cell status.

Abstract
This disclosure describes methods and apparatus for indicating battery cell status on a battery pack assembly used during mechanical ventilation. Embodiments described herein seek to provide methods for indicating battery cell status on the exposed exterior of a battery assembly pack both when the battery is in use and when the battery is not in use during mechanical ventilation. Embodiments utilize power from the ventilator as well as power from the battery pack itself to light the indicators during periods of battery use and non-use, respectively. Embodiments described herein further seek to provide an apparatus indicating battery cell status on the exposed exterior of the battery pack assembly during mechanical ventilation. Embodiments described herein further seek to provide an apparatus for a battery pack assembly used during mechanical ventilation. Embodiments described herein seek to provide a system for a ventilation system with an inserted battery pack assembly.

12. A system for mechanical ventilation, the system comprising one or more battery pack assemblies inserted into a ventilation system, the system further comprising:
-
a pneumatic system for circulating breathing gases to and from a patient, the pneumatic system further comprising a compressor for pressurizing gases; a controller for controlling operation of the one or more inserted battery pack assemblies, wherein the controller is further configured to; receive a first cell status for a first battery pack assembly, wherein the first cell status for the first battery pack assembly is displayed on a first status indicator on an exposed exterior of the first battery pack assembly, and wherein the first cell status indicates information about the first battery pack assembly; receive low voltage information in the first cell status; disconnect the ventilation system from the first battery pack assembly; connect the ventilation system to a second battery pack assembly and display a second cell status for the second battery pack assembly on a second status indicator, wherein the second cell status indicates information about the second battery pack assembly, and wherein the second cell status indicates different battery information than the first cell status. - View Dependent Claims (13, 14, 15, 16)
