Location detection systems and methods
A location detection system identifies the locations of medical devices such as patient support apparatuses and/or patient care devices within a medical facility. The devices communicate via a wired connection to one or more medical facility systems (e.g. nurse call system, computer network, etc.), and/or via a wireless connection to such systems. The location detection system automatically determines location information of the devices and communicates the location information so that the recipient of any outgoing alerts and/or other information sent from the devices is apprised of the location of the particular device sending the alert or other information. Caregivers are thereby able to respond to the correct location of an alert, and software systems such as EMR systems, admission discharge and transfer (ADT) systems, etc. are able to correlate transmitted device data with the location and/or patient assigned to that location.
1. A location detection system comprising:
stationary module positioned at a known location within a facility, the stationary module including a first unique identifier and a first wireless transceiver adapted to transmit the first unique identifier; and
a mobile patient support apparatus having a second unique identifier and a second wireless transceiver, the mobile patient support apparatus adapted to receive the first unique identifier from the stationary module, the mobile patient support apparatus further including a data table that correlates the first unique identifier to the known location within a healthcare facility, the mobile patient support apparatus adapted to transmit the known location to a wireless access point of a computer network using a third wireless transceiver, and the mobile patient support apparatus adapted to only transmit the known location to the wireless access point of the computer network if the mobile patient support apparatus and the stationary module successfully link to each other utilizing fourth and fifth wireless transceivers, the fourth and fifth wireless transceivers having a shorter communication range than the first and second wireless transceivers.
2. The location detection system of claim 1 wherein the first and second wireless transceivers operate in accordance with Institute of Electrical and Electronics Engineers (IEEE) standard 802.15.1, and the third wireless transceiver operates in accordance with IEEE standard 802.11.
3. The location detection system of claim 1 wherein the mobile patient support apparatus is adapted to receive the data table from a server coupled to the computer network, the mobile patient support apparatus receiving the data table via the third wireless transceiver.
4. The location detection system of claim 3 wherein the mobile patient support apparatus requests the data table from the server in response to a triggering event.
5. The location detection system of claim 1 wherein the data table correlates the first unique identifier to a room number of the healthcare facility.
6. A location detection system comprising:
a mobile patient support apparatus having a first unique identifier and a first wireless transceiver, the mobile patient support apparatus adapted to transmit the first unique identifier via the first wireless transceiver; and
a stationary module positioned at a fixed location within a healthcare facility, the stationary module including a second unique identifier and a second wireless transceiver adapted to receive the first unique identifier from the mobile patient support apparatus, the stationary module also including a data table that correlates the first unique identifier to the fixed location within the healthcare facility, and the stationary module being adapted to transmit the fixed location and the first unique identifier to a wireless access point of a computer network using a third wireless transceiver, wherein the stationary module is adapted to only transmit the fixed location and the first unique identifier to the wireless access point of the computer network if the mobile patient support apparatus and the stationary module successfully link to each other utilizing fourth and fifth wireless transceivers, the fourth and fifth wireless transceivers having a shorter communication range than the first and second wireless transceivers.
7. The location detection system of claim 6 wherein the stationary module is adapted to transmit the fixed location to the mobile patient support apparatus via the second wireless transceiver.
8. The location detection system of claim 6 wherein the first and second wireless transceivers operate in accordance with Institute of Electrical and Electronics Engineers (IEEE) standard 802.15.1, and the third wireless transceiver operates in accordance with IEEE standard 802.11.
9. The location detection system of claim 6 wherein the stationary module is adapted to receive the data table from a server coupled to the computer network, the stationary module receiving the data table via the third wireless transceiver.
10. The location detection system of claim 6 wherein transmitting the fixed location to the wireless access point includes transmitting a room number of a room that includes the fixed location.
