WIRELESS CHARGING SYSTEM FOR MEDICAL DEVICES
A wireless charging system for recharging batteries in a medical environment includes a charging station. The charging station may include an opening to receive batteries and an outlet for dispensing charged batteries, wherein the outlet comprises a slot in a front cover. The charging station also includes a wireless power transmitter having a transmitting antenna.
1 . A method for wireless charging batteries for a medical device, the method comprising:
receiving a first battery through an inlet at a top of a charging station, the first battery being in a first orientation;
receiving a second battery through the inlet and onto the first battery to form a stack of batteries inside the charging station, the second battery being in a second orientation;
transmitting power wirelessly to the first battery in the first orientation and concurrently transmitting power wirelessly to the second battery in the second orientation;
providing the first battery in a charged state through an outlet at a bottom of the charging station; and
subsequently, providing the second battery in a charged state through the outlet.
2 . The method of claim 1 , wherein the first battery and the second battery are received through in the inlet in a depleted state.
3 . The method of claim 1 , wherein the first battery and the second battery are concurrently charged by a single transmitting antenna.
4 . The method of claim 3 , wherein the transmitting antenna is positioned behind a rear plate, wherein the first battery and the second battery are positioned between the rear plate and a front cover when being charged.
5 . The method of claim 1 , further comprising:
detecting, by the charging station an error state; and
changing an indicator light on the charging station to communicate the error state.
6 . The method of claim 1 , wherein the first battery is within a sterile barrier.
7 . The method of claim 1 , wherein the power is wirelessly transmitted to a receiving antenna within the first battery.
8 . The method of claim 1 , wherein the first battery is a battery for a video laryngoscope.
9 . A method for wireless charging batteries for a medical device, the method comprising:
receiving a first battery through an inlet at a top of a charging station, wherein the inlet is an opening defined between a rear plate and a transparent front cover of the charging station;
receiving a second battery through the inlet and onto the first battery to form a stack of batteries inside the charging station, the second battery being in a different orientation from the first battery;
wirelessly transmitting power, via a transmitting antenna inside the rear plate, concurrently to the first battery and the second battery;
providing the first battery in a charged state through an outlet at a bottom of the charging station, the outlet at least partially defined in the front cover of the charging station; and
subsequently, providing the second battery in a charged state through the outlet.
10 . The method of claim 9 , wherein the first battery and the second battery are received through in the inlet in a depleted state.
11 . The method of claim 9 , further comprising:
detecting, by the charging station an error state; and
changing an indicator light on the charging station to communicate the error state.
12 . The method of claim 9 , wherein the first battery is within a sterile barrier.
13 . The method of claim 9 , wherein the power is wirelessly transmitted to a receiving antenna within the first battery.
14 . The method of claim 9 , wherein the first battery is a battery for a video laryngoscope.
15 . A method for wireless charging batteries for a medical device, the method comprising:
receiving, by a charging station, a first battery through an inlet at a top of the charging station, wherein the inlet is an opening defined between a rear plate and a transparent front cover of the charging station;
receiving, by the charging station, a second battery through the inlet and onto the first battery to form a stack of batteries inside the charging station;
wirelessly transmitting power, via a transmitting antenna inside the rear plate, concurrently to the first battery and the second battery;
receiving, by a first receiving antenna of the first battery, the wirelessly transmitted power;
during receipt of the wirelessly transmitted power, illuminating, by the first battery, a first indicator on the first battery to indicate a charge state of the first battery, wherein the first indicator is viewable through the transparent front cover;
receiving, by a second receiving antenna of the second battery, the wirelessly transmitted power; and
during receipt of the wirelessly transmitted power, illuminating, by the second battery, a second indicator on the second batter to indicate a charge state of the first battery, wherein the first indicator is viewable through the transparent front cover.
16 . The method of claim 15 , further comprising:
dispensing the first battery in a charged state through an outlet at a bottom of the charging station, the outlet at least partially defined in the front cover of the charging station; and
subsequently, dispensing the second battery in a charged state through the outlet.
17 . The method of claim 15 , wherein the first battery is within a sterile barrier.
18 . The method of claim 15 , wherein the first battery is a battery for a video laryngoscope.
19 . The method of claim 15 , further comprising:
detecting, by the charging station an error state; and
changing an indicator light on the charging station to communicate the error state.
20 . The method of claim 9 , wherein the first battery and the second battery are received through in the inlet in a depleted state.
