Abstract

<P>PROBLEM TO BE SOLVED: To keep the voice at a confortable volume without performing a troublesome operation when a patient calls a medical worker by a nurse call system. <P>SOLUTION: When call by a slave unit 1 is performed, a control part 11 for a master unit extracts age information of an applicable patient from a patient information storage part 13 and a voice processing part 16 processes the voice to be output when an age of the patient is equal to or higher than a predetermined value. Thus, since the voice input by a microphone 15 for the master unit is automatically processed according to the age of the patient, the voice output from a speaker 5 for the slave unit becomes easy to catch corresponding to the age of the patient. Consequently, the patient can obtain the voice which is easy to catch without performing the troublesome operation. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a nurse call system for calling a nurse or a caregiver in response to a request from a patient or a care recipient in a hospital or a care facility.

  Conventionally, in the nurse call system, a nurse call cordless handset, a nurse and a caregiver (hereinafter, collectively) that are installed in the vicinity of a patient or a care recipient (hereinafter collectively referred to as a patient) (for example, in the vicinity of a bed). The nurse call master unit installed in the room where the health care worker is located is connected by wire or wireless. Then, when the patient operates the nurse call slave unit, the nurse call master unit outputs a ringing tone or a melody tone. A nurse or a caregiver listens to a ringing tone or melody sound emitted by the nurse call master unit, answers by a handset provided in the nurse call master unit, and talks with the patient.

  By the way, when the patient is an elderly person, there is a problem that the voice of the call by the nurse call system becomes difficult to hear due to factors such as senile deafness.

In order to solve such a problem, an intercom device that can select a sound quality that is easy for an elderly person to hear is known (Patent Document 1, etc.).

  In FIG. 1, the child device 1 is attached to a bed in a hospital room where a patient is present, and is connected to a parent device 10 installed in a nurse center or the like via a transmission line. Here, the plurality of slave units 1 are connected to one master unit 10 so as to be identifiable. A corridor lamp (not shown) or a controller (not shown) may be connected between the slave unit 1 and the master unit 10.

  The subunit | mobile_unit control part 2 controls each component of the subunit | mobile_unit 1. FIG. The call switch 3 generates a call signal by a patient operation and outputs the call signal to the child device control unit 2. Here, the call operation unit 3 includes a button (not shown) operated by the patient and a call signal generation unit (not shown) that generates a call signal by operating the button. The patient presses a button on the call operation unit 3 when he / she wants to call a medical worker.

  The slave unit communication interface 4 transmits the call signal input from the slave unit control unit 2 to the master unit 10. The slave unit communication interface 4 transmits the voice input to the slave unit microphone 6 to the master unit 10 as a voice signal. The slave unit communication interface unit 4 receives the audio signal input from the master unit 10.

  The handset speaker 5 outputs the sound based on the sound signal transmitted from the base unit 10 and input via the handset communication interface 4 to the outside. The handset microphone 6 inputs voice uttered by the patient. Thereby, a telephone call is performed between the child device 1 and the parent device 10.

  The base unit controller 11 controls each component of the base unit 10. The base unit communication interface 12 receives a call signal and a voice signal transmitted from the handset 1. The base unit communication interface 12 transmits the voice input by the base unit microphone described later and processed by the voice processing unit 16 to the handset 1.

  The patient information storage unit 13 stores fixed data unique to a patient such as a patient name, identification ID (identification), gender, blood type, age, and address. In addition, the patient information storage unit 13 stores semi-fixed data such as a patient's bed number, relief category, nursing level category, medical subject, and doctor in charge. The patient information storage unit 13 stores vital data such as body temperature, blood pressure, and respiratory rate, nursing plan data, nursing history data, and the like. Here, the respective data are associated and stored in the patient information storage unit 13.

  The display unit 14 identifies the patient from the bed number of the bed on which the call switch 3 is operated, and displays that the call has been made along with the patient's name and bed number. The base unit microphone 15 inputs a voice uttered by a medical worker.

  The voice processing unit 16 processes the voice input by the base unit microphone 15 according to the age of the patient stored in the patient information storage unit 13. Specifically, when the base unit communication interface 12 receives a call signal, the base unit control unit 11 has a response operation unit (for example, a response button or a handset) that does not show a response to the call signal. When operated, the following control is performed.

  The base unit controller 11 uses the bed number (corresponding to the patient identification information in the claims) included in the call signal input to the base unit communication interface 12 as a key to call the patient's age as the patient information. Extracted from the storage unit 13. When the parent device control unit 11 determines that the patient's age is equal to or greater than a predetermined age (for example, 50 years old or more), the parent device control unit 11 operates the voice processing unit 16. The sound processing unit 16 processes and outputs the sound so as to increase the volume of the sound input from the parent microphone 15. On the other hand, when the parent device control unit 11 determines that the patient's age is less than the predetermined age, the parent device control unit 11 stops the operation of the sound processing unit 16. The voice processing unit 16 outputs the voice input from the base unit microphone 15 as it is.

  When the base unit communication interface 12 receives a call signal, the base unit speaker 14 outputs a ringing tone generated by the base unit control unit 11. Further, the base unit speaker 14 outputs sound based on the audio signal from the handset 1 received by the base unit communication interface 12. In addition, an alarm unit may be separately provided that does not output the ringing tone from the main unit speaker 14 but sounds the ringing tone exclusively or displays the call. In response to these calling operations, base unit 10 performs a response operation using a response operation unit (not shown).

  The voice processed by the voice processing unit 16 is transmitted to the slave unit 1 via the master unit communication interface 12. The slave unit communication interface 4 of the slave unit 1 receives the processed voice signal in the same manner as a normal voice signal. Moreover, the subunit | mobile_unit speaker 5 outputs the audio | voice by the processed audio | voice signal input via the subunit | mobile_unit communication interface 4 to the exterior.

  As described in detail above, according to the present embodiment, when a call is made by the child device 1, the parent device control unit 11 extracts the age information of the corresponding patient from the patient information storage unit 13, The voice processing unit 16 processes and outputs a voice when the patient's age is a predetermined value or more. As a result, the voice input from the base unit microphone 15 is automatically processed according to the age of the patient, so that the voice output from the handset speaker 5 is easy to hear according to the age of the patient. It becomes. Therefore, the patient can obtain a voice that is easy to hear without troublesome operations.

  In the above-described embodiment, the sound processing by the sound processing unit 16 increases the sound volume, but is not limited thereto. For example, it is possible to make the sound easy to hear by shifting the sound input by the microphone 15 for the parent device to a low frequency band. Further, by converting the speech speed of the voice input by the base unit microphone 15 to be slow, the voice can be easily heard. In addition, the voice input from the microphone 15 for the parent device is recognized and converted into text, transmitted to the child device 1 and displayed on the display unit (not shown) of the child device 1, thereby allowing the patient to The sound from 10 can be visually recognized. Further, these voice processing methods may be combined.

  Further, in the above-described embodiment, when the age of the calling patient is equal to or higher than a predetermined age, the base unit control unit 11 increases the volume of the voice input from the base unit microphone 15. However, the present invention is not limited to this. For example, the base unit control unit 11 may vary the degree of processing by the voice processing unit 16 depending on the age value of the patient who has called. For example, when the patient's age is 50 years or older, the parent device control unit 11 increases the volume by 10% by the voice processing unit 16, and when the patient's age is 60 years or older, the parent device The control unit 11 increases the volume by 20% using the voice processing unit 16, and when the patient's age is 70 years or older, the control unit 11 for the master unit increases the volume by 30% using the voice processing unit 16. For example, the degree of voice processing may be improved as the patient's age increases.

  In the above-described embodiment, the voice processing unit 16 is provided in the parent device 10, but is not limited to this. For example, as shown in FIG. 2, the voice processing unit 7 may be provided in the slave unit 1. Specifically, when a response operation is performed with respect to the call signal received by the base unit communication interface 12, the base unit control unit 11 uses the patient identification information included in the call signal to store the patient information storage unit 13 The age information of the patient is extracted from the information, a voice processing instruction signal is generated according to the age information of the patient, and transmitted from the communication interface 12 for the master unit. When the slave unit communication interface 4 receives the voice processing instruction signal, the slave unit control unit 2 controls the voice processing unit 7 to process the voice output from the slave unit speaker 5. ing.
