The receiver receives a request for rescue of a rescued person and rescued person location information. The emergency medical staff arrival time estimation unit estimates an emergency medical staff arrival time at which an emergency medical staff arrives at the rescued person based on the rescued person location information. The acquisition unit acquires user location information of a registered user that is a candidate for a rescuer. The user arrival time estimation unit estimates the user arrival time when the registered user arrives at the rescued person based on the user location information. The transmitter transmits the request for rescue to the registered user that is able to arrive earlier than the emergency medical staff. ## Claims ### Claim 1 A rescue system comprising: a receiver for receiving a request for rescue of a rescued person and rescued person location information; an emergency medical staff arrival time estimation unit for estimating an emergency medical staff arrival time at which an emergency medical staff arrives at the rescued person based on the rescued person location information; an acquisition unit for acquiring user location information of a registered user that is a candidate for a rescuer; a user arrival time estimation unit for estimating a user arrival time at which the registered user arrives at the rescued person based on the user location information; and a transmitter for transmitting the request for rescue to the registered user that is able to arrive earlier than the emergency medical staff, wherein the emergency medical staff arrival time estimation unit and the user arrival time estimation unit are configured to continually monitor arrival time of the emergency medical staff and the registered user, respectively, and when it is determined that the emergency medical staff is expected to arrive at the rescued person earlier than the rescuer, the rescuer is provided with an option to cancel traveling. ### Claim 2 (depends on 1) The rescue system according to claim 1, further comprising a determination unit for determining whether to make the request for rescue to the registered user based on the emergency medical staff arrival time and the user arrival time, wherein when the determination unit determines to make the request for rescue to the registered user, the transmitter transmits the request for rescue. ### Claim 3 (depends on 1) The rescue system according to claim 1, further comprising: a candidate display unit for displaying, as the candidate for the rescuer, the registered user that is able to arrive earlier than the emergency medical staff, based on the emergency medical staff arrival time and the user arrival time; and an acceptance unit for accepting making the request for rescue to the registered user displayed, wherein the transmitter transmits the request for rescue to the registered user accepted by the acceptance unit. ### Claim 4 (depends on 1) The rescue system according to claim 1, wherein: the user arrival time estimation unit estimates the user arrival time for a plurality of modes of transportation; and the transmitter transmits, to the registered user that is able to arrive earlier than the emergency medical staff for at least one of the modes of transportation, information on the modes of transportation and the request for rescue. ### Claim 5 (depends on 2) The rescue system according to claim 2, wherein: the registered user includes a healthcare worker having qualification or expertise in rescue; the receiver also receives information on a type of rescue of the rescued person; and the determination unit determines whether to make the request for rescue to the registered user, giving priority to the registered user having the qualification or the expertise matching the type of rescue of the rescued person among a plurality of the registered users that are able to arrive earlier than the emergency medical staff. ### Claim 6 (depends on 3) The rescue system according to claim 3, wherein: the registered user includes a healthcare worker having qualification or expertise in rescue; the receiver also receives information on a type of rescue of the rescued person; and the candidate display unit displays, as the candidate, the registered user having higher priority and matching the type of rescue of the rescued person, based on information on the qualification or the expertise of the registered user.
