The ostomy appliance includes a base plate, and the accessory device includes a memory, a processor, and an interface coupled to the processor. The interface is configured to communicate with the monitor device. The interface includes a display device and is configured to obtain monitor data from the monitor device coupled to the ostomy appliance. The processor is configured to determine an operating state of the ostomy appliance, determine respective locations of one or more changing rooms based on the operating state, and output to the display device directions to a changing room of the one or more changing rooms. ## Claims ### Claim 1 An accessory device for an ostomy system comprising a monitor device and an ostomy appliance, the ostomy appliance comprising a base plate, the accessory device comprising: a memory; a processor; and an interface coupled to the processor and configured to communicate with the monitor device, wherein the interface comprises a display device and is configured to obtain monitor data from the monitor device coupled to the ostomy appliance, wherein the processor is configured to: determine an operating state of the ostomy appliance; determine respective locations of one or more changing rooms based on the operating state; and output to the display device directions to a changing room of the one or more changing rooms. ### Claim 2 (depends on 1) The accessory device according to claim 1, wherein determining the operating state of the ostomy appliance comprises determining an operating state of the base plate. ### Claim 3 (depends on 2) The accessory device according to claim 2, wherein determining the operating state of the base plate comprises determining a remaining wear time of the base plate. ### Claim 4 (depends on 1) The accessory device according to claim 1, wherein the interface comprises an input device configured to receive input from a user. ### Claim 5 (depends on 1) The accessory device according to claim 1, wherein the interface comprises an input device configured to receive input from a user and wherein the changing room is selected based on a selection from the one or more changing rooms by the user via the input device. ### Claim 6 (depends on 1) The accessory device according to claim 1, wherein the interface comprises an input device configured to receive input from a user and wherein the changing room is selected based on a selection of a mode of transportation by the user via the input device. ### Claim 7 (depends on 1) The accessory device according to claim 1, wherein the interface is configured to receive one or more configuration criteria from a user of the accessory device and wherein the processor is further configured to determine whether the one or more changing rooms satisfy the one or more configuration criteria, and configured to output to the display device an indication in accordance with the determination that the one or more changing rooms satisfy the one or more configuration criteria. ### Claim 8 (depends on 1) The accessory device according to claim 1, wherein the interface is configured to receive one or more configuration criteria from a user of the accessory device and wherein the processor is further configured to determine whether the one or more changing rooms satisfy the one or more configuration criteria, and configured to output to the display device an indication in accordance with the determination that the one or more changing rooms satisfy the one or more configuration criteria and wherein the processor is further configured to obtain a ranking of the one or more changing rooms and to determine whether the one or more changing rooms meet or exceed a threshold ranking. ### Claim 9 (depends on 1) The accessory device according to claim 1, wherein the interface is configured to receive one or more configuration criteria from a user of the accessory device and wherein the processor is further configured to determine whether the one or more changing rooms satisfy the one or more configuration criteria, and configured to output to the display device an indication in accordance with the determination that the one or more changing rooms satisfy the one or more configuration criteria and wherein the one or more configuration criteria comprise changing rooms that are handicap accessible. ### Claim 10 (depends on 1) The accessory device according to claim 1, wherein the processor is configured to determine a location of the accessory device and the changing room that is closest to the location of the accessory device from the one or more changing rooms. ### Claim 11 (depends on 1) The accessory device according to claim 1, wherein the processor is configured to receive a future location of a user and determine respective locations of the one or more changing rooms based on the future locations. ### Claim 12 A method of operating an accessory device for an ostomy system comprising a monitor device and an ostomy appliance, the ostomy appliance comprising a base plate, the method comprising: determining an operating state of the ostomy appliance; determining respective locations of one or more changing rooms based on the operating state; and providing directions to a changing room of the one or more changing rooms. ### Claim 13 (depends on 12) The method according to claim 12, wherein to determine the operating state of the ostomy appliance, the method comprises determining an operating state of the base plate. ### Claim 14 (depends on 13) The method according to claim 13, wherein determining the operating state of the base plate comprises determining a remaining wear time of the base plate. ### Claim 15 (depends on 12) The method according to claim 12, further comprising receiving an input and wherein the one or more changing rooms are selected based on the received input. ### Claim 16 A system, comprising: at least one processor; and a memory storing instructions that, when executed by the at least one processor, cause the system to perform a set of operations, the set of operations comprising: determining an operating state of the ostomy appliance; determining respective locations of one or more changing rooms based on the operating state; and providing directions to a changing room of the one or more changing rooms. ### Claim 17 (depends on 16) The system of claim 16, wherein the operating state of the ostomy appliance is determined based on an operating state of a base plate of the ostomy appliance. ### Claim 18 (depends on 17) The system of claim 17, wherein the operating state of the base plate corresponds to a remaining wear time of the base plate. ### Claim 19 (depends on 16) The system of claim 16, further comprising receiving user input indicating a selection of the changing room from the one or more changing rooms. ### Claim 20 (depends on 16) The system of claim 16, further comprising selecting the changing room from the one or more changing rooms based on user input indicating a mode of transportation by a user.
