When a call is made from a nurse call sub-unit, an IP adaptor 7 identifies a predetermined telephone number corresponding to a calling type included in a calling signal output from a controller unit 5. By the transmission of the calling signal, which includes the identified predetermined telephone number as a calling party, from an SIP server 8 to the IP mobile telephone 10, the IP mobile telephone 10 recognizes the predetermined telephone number included in the calling signal, as the calling party. By enabling outputting the ringing tone which is set to the telephone number of the calling party through the telephone directory storage, it becomes sufficient only to register the predetermined telephone numbers as many as the number of calling types into the telephone directory of the IP mobile telephone 10.

Description

  The present invention relates to a nurse call system and a ringing tone control device, and more particularly, a patient calls a nurse by pressing a call button, and the called nurse performs an operation for a response so that the patient and the nurse can perform a response. It is suitable for use in a nurse call system configured to be able to make a call from a remote location.

  In general, nurse call systems used in hospitals and nursing care facilities are used when patients and care recipients (hereinafter simply referred to as patients) need the support of doctors, nurses, and caregivers (hereinafter simply referred to as nurses). In addition, the system is configured such that a patient can call a nurse by pressing a call button or the like of a nurse call cordless handset.

  In many nurse call systems, a call is made to a nurse call master unit installed in a nurse center, but a call is made to a PHS (Personal Handyphone System) terminal carried by a nurse via a private branch exchange (PBX). A nurse call system is also provided. In recent years, nurse call systems that include a SIP (Session Initiation Protocol) server and perform calls to IP (Internet Protocol) telephones have also been proposed (see, for example, Patent Documents 1 and 2).

  In the nurse call system described in Patent Document 1, the nurse call parent device and the portable nurse call parent device (IP phone) are provided with an IP transmission / reception circuit that enables IP communication between them. The nurse call master unit has a function of notifying the IP phone of a call from the nurse call slave unit and a function of enabling IP communication between the nurse call slave unit and the IP phone. In addition, an IP exchange that controls communication between the nurse call parent device and the IP telephone is connected to the nurse call parent device via a LAN.

  In addition, the nurse call system described in Patent Document 2 is a nurse call cordless handset that makes a call and a call from a patient in a room, and calls from the nurse call cordless handset (call history such as call source, call destination, and call time). It consists of a nurse call master unit that displays and makes a response call and a portable nurse call master unit (IP phone). The nurse call base unit and the IP telephone are connected to each other by a SIP server that connects the extensions.

  In the conventional nurse call system including these Patent Documents 1 and 2, when the patient calls by pressing the call button of the nurse call slave unit, the call is made and the nurse call master unit or portable nurse call is performed. It is notified by the master unit (PHS terminal or IP phone). In response to this, the nurse responds with the handset of the nurse call master unit, the PHS terminal carried by the nurse or the IP phone.

  Call notification to a nurse call parent device or a portable nurse call parent device is performed by display on a monitor screen, ringing sound, and ringing. For example, when a call is made from a nurse call cordless handset, a ringing tone sounds at the nurse call master phone or portable nurse call master phone, and patient information such as the name and room number of the calling patient is displayed on the monitor screen. Is displayed. In addition to patient information, some systems are configured to display call types such as general call / emergency call / ME call. The ME call is a call that is performed when a patient's abnormality is detected in a medical device connected to the nurse call slave.

  The nurse call system displays the call type on the monitor screen of the nurse call master unit or portable nurse call master unit when a call is made from the nurse call slave unit. Therefore, it is possible to take an appropriate response such as a quick response to a call with a high degree of urgency.

  However, there is a case where the display on the monitor screen cannot be immediately seen because the nurse is in the care of the patient or preparing for the treatment. In addition, even when a nurse holds a portable nurse call parent machine in a pocket, the display on the monitor screen cannot be seen immediately. In this case, there was a problem that the nurse could not immediately grasp the urgency of the call.

  There has been proposed a nurse call system in which a ringing tone can be distinguished and output from a nurse call parent device or a portable nurse call parent device according to the type of the call signal output from the nurse call child device (for example, And Patent Documents 3 and 4). In the nurse call system described in Patent Document 3, the normal call sound or the test ring tone can be distinguished and output from the nurse call parent device in accordance with the normal call signal or the test call signal output from the nurse call slave unit. Yes.

  Further, in the calling system described in Patent Document 4, in the telephone directory of the nurse call receiver (portable nurse call parent device), the telephone numbers obtained by combining the call type and the child device number are grouped for each call type. It is registered and a ringing pattern (vibration or ringing pattern) is set for each group (calling type). According to this technique, the nurse can grasp the urgency level of the call based on the ringing pattern.

  However, the nurse call system of Patent Document 3 switches the ring tone according to the call type in the nurse call parent device, and the portable nurse call parent device distinguishes and outputs the ring tone according to the call type. Can not.

  On the other hand, in the calling system of Patent Document 4, a ringing tone corresponding to the call type can be output even in a portable nurse call parent device. However, in the portable nurse call master unit, a telephone number that is a combination of the call type and the slave unit number must be registered in the phone book for each nurse call slave unit. Therefore, when the number of nurse call cordless handsets is large, the number of telephone numbers to be registered in the telephone book increases, and there is a problem that the registration work becomes complicated.
