Abstract

PROBLEM TO BE SOLVED: To improve the reliability of the medical information system by receiving a polling request from an emergency medical information center with precedence over other usual speech request so as to improve the operability. SOLUTION: A host computer of an emergency medical information center sends a polling request corresponding to information dealing with emergency to an information terminal equipment of each medical agency once a day, for example, to collect current information dealing with emergency. An exchange references a specific telephone number table to send a specific frequency call signal whose frequency is, e.g. 2100Hz only to a polling request of information dealing with emergency. A frequency discrimination circuit 33 receives a call signal received via a telephone line 12 via a call signal reception circuit 27 to discriminate the frequency. When the frequency of the call signal is 2100Hz, a changeover control circuit 36 controls a changeover switch 25 to connect the telephone line 12 to a MODEM 30. In this case, a tone ringer 34 stops call tone ringing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency medical information system, and more particularly to improvement of an emergency medical information terminal device installed in each medical institution.

[0002]

2. Description of the Related Art In general, each local government has constructed an emergency medical information system using a general public line network as a part of medical services for residents in its own administrative area.

FIG. 6 is a schematic block diagram of an emergency medical information system. For example, various medical institutions 2 such as hospitals existing in this municipality are connected to the emergency medical information center 1 installed in a medical association, etc., via telephone lines 3.

The emergency medical information center 1 has two medical institutions 2.
Emergency response information such as the number of empty bets and emergency response courses is stored and held in the host computer 4. Then, for example, when a notification of the occurrence information of the emergency patient is received from the fire department, the police station, or the general public, the medical institution 2 that can accept the patient is selected based on the emergency response information stored in the host computer 4. Then, the selected result is responded to the caller.

The fire department, the police station, or the general public who is informed of the medical institution 2 of the recipient from the emergency medical information center 1 carries the corresponding emergency patient to the instructed medical institution 2. Since the number of vacant beds in each medical institution 2 and the emergency correspondence subject are changed frequently, the host computer 4 of the emergency medical information center 1 sends the information terminal device 7 of each medical institution 2 to the information terminal device 7 at a fixed cycle such as once a day. Then, a polling request for emergency response information is transmitted via the telephone line 3.

The information terminal device 7 of each medical institution 2 has not only a normal telephone function but also automatic data reception and data transmission functions via a modem. The information terminal device 7 is the host computer 4 of the emergency medical information center 1.
When receiving the polling request from the modem via the modem, the emergency response information stored and held in its own storage unit is transmitted to the host computer 4 of the emergency medical information center 1 via the telephone line 3.

The host computer 4 of the emergency medical information center 1 sequentially transmits the polling request to each medical institution 2 at a predetermined time interval required for transmitting the polling request and receiving the emergency response information, and each medical institution 2 The emergency response information is sequentially collected from, and the emergency response information stored in its own file is updated to the latest information.

In such an emergency medical information system, when the operator of the emergency medical information center 1 selects the medical institution 2 based on the emergency response information stored in the host computer 4, the telephone 5 for confirmation is selected. The information terminal device 7 of the medical institution 2 selected in step 1 is called, the operator near the information terminal device 7 is notified that the emergency patient is going, and then the selection result is returned to the whistleblower.

[0009]

However, the emergency medical information system having the above-mentioned structure still has the following problems to be improved. As described above, the information terminal device 7 provided in each medical institution 2 has an automatic data reception function and an automatic transmission function via a modem in addition to the normal telephone function.

Therefore, when a call signal of 16 Hz is received from the outside through the telephone line 3, the call signal cannot be distinguished from the polling request from the host computer 4 or the call request from the general telephone 5.

Generally, as a procedure of automatic call reception using a modem, when a call signal of 16 Hz elapses for a predetermined time, the telephone line is switched to the modem side to automatically receive the call in the automatic call reception mode, and the caller is called. A communication line is formed with a computer. Then, via the formed communication line, a polling request from the source computer is received, and based on this polling request, access processing to the emergency response information stored in its own storage unit is started.

However, for the operator near the information terminal device 7, the polling request is mistaken for the call request from the general telephone and the handset is picked up and the telephone line is forcibly switched to the call circuit side. I have a concern.

When the telephone line is forcibly switched to the call circuit side, the emergency medical information center 1 on the transmission side of the polling request
Since there is no response to the polling request, the host computer 4 of the information terminal device 7 of the medical institution 2 concerned
Is judged to be abnormal. Then, the information collection process for the next medical institution 2 is started. When the information collecting process for all the medical institutions 2 is completed, the polling request is transmitted again to the medical institutions 2 that could not collect information earlier.

Even at this point, if the operator mistakenly picks up the handset (handset) and responds, the host computer 4 of the emergency medical information center 1 will fail to collect information twice from the relevant medical institution 2. Stop collecting the third information.

Therefore, the emergency response information of the medical institution 2 stored in its own file is not updated correctly,
There is a problem that correct emergency response information cannot be provided to the fire department, police station, or the general public who are inquiries.

Further, even for the operator near the information terminal device 7 of the medical institution 2, the polling execution time is set for the time being, but as long as the ringing tone is heard, the polling request and the call request cannot be distinguished. Therefore, there is a concern of making an incorrect response, which is very annoying.

The present invention has been made in view of such circumstances, and when the polling request by the computer is automatically stopped, the ringing tone is automatically stopped so that the polling request can be surely responded to, and the emergency medical information center is provided. An emergency medical information terminal that can reliably transmit emergency response information, improve the reliability of the entire emergency medical information system, and can reliably respond only to call requests and reduce the mental burden on the operator. The purpose is to provide a device.

[0018]

According to the present invention, a computer connected to an emergency medical information center and a telephone set are connected via a telephone line, and a modem transmits a polling request from the computer of the emergency medical information center via the telephone line. A call is automatically received via the emergency response information to the computer of the emergency medical information center as a polling response, and a manual call is received using the call circuit in response to a call request from the telephone of the emergency medical information center via the telephone line. It is applied to the emergency medical information terminal device that performs.

In order to solve the above-mentioned problems, the emergency medical information terminal device described above is provided with a switching means for switching a telephone line to a communication circuit or a modem, and a call signal for receiving a call signal received through the telephone line. Receiving means, frequency measuring means for measuring the frequency of the calling signal received by the calling signal receiving means, and connecting the telephone line to the calling circuit side when the frequency measured by the frequency measuring means is the specified calling signal frequency, , A line control means for sending a switching signal to the switching means for connecting the telephone line to the modem when the frequency is a predetermined specific frequency, and a call for stopping ringing of the ringing tone when the frequency measured by the frequency measuring means is the specific frequency. And a sound stopping means.

In the emergency medical information terminal device having such a configuration, the frequency of the calling signal received through the telephone line is, for example, a specified frequency of 16 Hz and, for example, 2100 Hz.
And the specific frequency of.

Specifically, in the exchange installed in the telephone station, a specific source telephone number and a specific destination telephone number are registered, and a specific telephone number of the specific source telephone number is specified from the telephone terminal. Only when the telephone terminal having the destination telephone number is called, the call signal of the specific frequency is transmitted from the exchange to the destination telephone terminal.

In the present invention, the specific source telephone number is the telephone number of the computer of the emergency medical information center, and the specific destination telephone number is the telephone number of the emergency medical information terminal device of the present application.

Therefore, the emergency medical information terminal device on the receiving side detects the frequency of the calling signal to determine whether the calling signal is a polling request from the computer of the emergency medical information center or a call request from a general telephone. It can be easily distinguished whether it is due to. And
In the case of a polling request, the ringing tone is stopped because the telephone line is switched to the modem side to automatically receive the call through the modem.

Therefore, the operator in the vicinity of the emergency medical information terminal device does not accidentally pick up the handset and respond to the polling request from the computer of the emergency medical information center. On the other hand, in the case of a normal call request, a ringing tone is sounded as usual to inform the operator.
