Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a medical diagnostic device with improved communication equipment.

[Conventional technical background]

Many medical diagnostic devices, such as diagnostic X-ray devices, scintillation camera devices, and CT scanners, perform diagnosis with a patient placed on a bed. Since these diagnostic devices use radiation for diagnosis, the patient is placed in a separate room from the operator (physician, technician) who performs the diagnosis.

Therefore, a communication means is required for communicating with the patient operator and giving instructions, and medical diagnostic equipment is provided with communication equipment for this purpose.

Conventionally, this communication equipment has microphones 1a and 1 on the operator side and the patient side, respectively, as shown in Fig. 1.
b and speakers 2a, 2b are provided, and one of the momentary type (automatic return type) two-system, two-circuit changeover switch 4 is connected to the input and output sides of one amplifier 3, respectively. By switching, the circuit configuration was such that one side could be used as a transmitter and the other as a receiver.

That is, by connecting the normally closed side contact of the changeover switch 4 to the patient-side microphone 1b, when the changeover switch 4 is not operated, the patient's voice is picked up by the microphone 1b, amplified by the amplifier 3, and then operated. The signal is sent to the operator side speaker 2a and transmitted to the operator side. Place this route in listen mode (Listen)
It's called Mode.

In addition, when transmitting from the operator side to the patient side, operate the changeover switch 4, change the changeover switch 4 to the normally open side contact, connect the operator side microphone 1a to the amplifier 3, and after amplifying the sound, send it to the patient side. This is done by giving it to the speaker 2b. This route is called talk mode.

The reason for having these two modes, listen mode and talk mode, is to prevent the contents of the conversation on the operator's side from being inadvertently leaked to the patient's side.

However, in such conventional methods, the patient is unilaterally under the control of the operator and cannot know what condition he or she is in.

Patients may feel anxious, especially if the diagnosis takes a long time.

For example, in CT Sukiyana, you are left alone in an isolated room for 15 to 30 minutes. Even under normal circumstances, people would feel anxious if they were placed in such a stressful situation, but it is even more so when they are sick.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a medical diagnostic apparatus having a broadcasting facility that can automatically notify the patient of the current situation upon request.

[Summary of the invention]

That is, in order to achieve the above object, the present invention provides a diagnostic device that performs diagnosis using a plurality of operations and outputs the operation status, and a diagnostic device that stores in advance voice messages to the subject corresponding to each of the above-mentioned operations. voice control that selects from the storage section a voice message corresponding to the operating state of the diagnostic device at the time of operation of the switch, based on a storage section in which the test subject is operating, a switch pressed by the subject, and the output from the diagnostic device; Department and
The apparatus is configured to include a voice reproduction section that reproduces the selected voice message near the subject.

The diagnostic device is configured to perform diagnosis through a plurality of operations and output the operation status, and the storage unit stores in advance voice messages to the subject corresponding to each of the above-mentioned operations. When the test subject presses the switch, the voice control section selects from the storage section a voice message corresponding to the operating state of the diagnostic device at the time the switch is activated, based on the output from the diagnostic device. and,
The audio reproduction unit reproduces the selected audio message near the subject. Therefore, when the subject presses the switch himself/herself, the subject can be informed by voice of the current operating status of the diagnostic device, and can grasp the situation at any time. In addition, without bothering the operator,
Since the operating state of the diagnostic device is communicated to the subject when the subject operates the switch, there is little worry of making the subject anxious.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG.

In the figure, 1a and 1b are microphones, 2
Reference numerals a and 2b are speakers, 3 is an amplifier, and 4 is a changeover switch located at the operator's hand, which are exactly the same as the configuration shown in FIG. 1.

That is, the microphone 1b on the operator's side is connected to the amplifier 3 through the normally open contact side of one switch of the momentary dual circuit changeover switch 4, and the microphone on the patient's side is connected to the amplifier 3 through the normally closed contact side of one switch.
The output side of the amplifier 3 is connected to the speaker 2a on the operator side via the normally closed contact side of the other switch of the changeover switch 4, and to the speaker 2a on the patient side via the normally open contact side. 2b. 5 is a medical diagnostic device such as a CT scanner, 6 is a control device that controls this CT scanner 5, 7 is a voice controller that generates an output corresponding to the control content of this control device 6, and 8 is this voice controller. A voice storage device outputs a memorized voice corresponding to the output of 7, an amplifier 9 amplifies the output of this voice storage device 8, and 10 a two-system, two-circuit momentary type changeover switch located on the patient's side. . One system of this changeover switch 10 has its normally closed side connected to the output side of the amplifier 3, its normally open side connected to the output side of the amplifier 9, and its fixed terminal side connected to the speaker 2 on the patient side.
The output of one of the amplifiers 3 and 9 is applied to the speaker 2b by turning on/off the changeover switch 10. The switch in the other system of the changeover switch 10 has its fixed terminal side connected to the voice controller 7, and its normally open side connected to ground, so that when the switch is operated, a ground potential is applied to the voice controller 7. The voice controller 7 is activated.

In this apparatus having such a structure, only the output of the microphone 1b on the patient side is inputted to the speaker 2a on the operator side via the amplifier 3 when the changeover switches 4 and 10 are not operated.
Therefore, in this state, only the patient's voice is unilaterally transmitted to the operator. Furthermore, when the changeover switch 4 is operated, the microphone 1b on the patient side is disconnected, the microphone 1a on the operator side is connected to the amplifier 3, and the output of this amplifier 3 is given only to the patient side speaker 2b. This allows the operator's voice to be transmitted to the patient.

The above is exactly the same as before.

This device is characterized in that the current status of the diagnostic device can be automatically notified by a changeover switch 10 provided at the patient's hand.

In other words, CT, which is one of the medical diagnostic devices, is used here.
Take Sukiyana as an example, a CT scan in which a patient is diagnosed
An audio output system is provided that outputs audio corresponding to the control content of the CT controller 6 that controls the scanner 5, and by pressing the switch 10 in the patient's hand, the current operating status of the CT apparatus can be audio broadcasted. It's like this.

That is, the CT controller 6 is placed in a separate room for the operator, which is isolated from the patient's side, and the operator can start imaging by pressing various command buttons or switches on the operation desk of the CT controller 6. The CT controller 6 is activated to set the region of interest of the reconstructed image and to generate various other commands and perform corresponding controls. In addition, the CT controller 6 performs imaging, that is, X-ray exposure, collects data, and then performs image reconstruction based on this data, which is performed by a computer according to a program. Therefore, outputs indicating various operating conditions can be easily obtained.

Therefore, in this device, the audio controller 7 obtains an output indicating this operating status and generates a preset output for controlling the audio storage device 8 corresponding to this output.
is provided, and the audio storage device 8 is controlled by this output.

The voice storage device 8 stores voice messages corresponding to the CT control device 6. For example, "It will be over in 5 minutes." or "The doctor is currently conducting an examination. Please wait a moment."
or "X-ray exposure is in progress."

In this device, the voice controller 7 is started by operating the changeover switch 10 on the patient's hand, so when the patient wants to know the situation, by operating the changeover switch 10, the speaker 2b on the patient side is activated. is switched to the amplifier 9 side by the changeover switch 10, and at the same time the audio controller 7 is started.
A voice storage device 8 control output corresponding to the operation information of the CT control device 6 is generated. As a result, the audio storage device 8 generates an audio message output corresponding to the operation information, which is applied to the speaker 2b via the amplifier 9 and the changeover switch 10.

This allows the patient to know the current situation.

On the other hand, in a situation where the changeover switch 4 is not operated, the communication equipment system for dialogue between the patient side and the operator side is in the listen mode where only the patient's voice is transmitted.
In this device, only the speaker 2b on the patient side is connected to the system that broadcasts CT scanner information.
Information broadcast by the patient-side speaker 2b is transmitted to the operator-side speaker 1a via the patient-side microphone 1b.

Therefore, the operator can infer the patient's psychological state.

The changeover switch 10 for patient operation is of a type that closes to the normally open side only while it is pressed, but a self-holding circuit or the like is provided to keep the switch self-holding until the end of the message to prevent audio interruption. You may try to prevent it.

〔Effect of the invention〕

As described in detail above, the present invention provides a medical diagnostic device in which the patient side and the operator side are isolated and the diagnostic device is controlled by remote control to perform diagnosis. transmitting means and receiving means for voice communication, and these are always kept in the transmitting state on the patient side and in the receiving state on the operator side, and the patient side is kept in the receiving state by operation on the operator side, and the patient side is always kept in the receiving state, and a switch for switching the side to a transmitting state; a control means for obtaining the operating state of the diagnostic device and generating an output corresponding to the operating information; and a control means for storing voice message information corresponding to the operating information in advance; a voice storage means for outputting corresponding voice message information; and a switch provided on the patient side for starting the control means when operated by the patient and inputting the output of the voice message information to the reception means on the patient side. When the patient operates a switch on the patient's side, a voice message is played that displays the current operating information of the diagnostic device, such as ``Image reconstruction is in progress,'' so the patient can immediately know the current status. In addition to being able to relieve the psychological anxiety caused by standing upright for a long time, the voice message sent to the receiving means on the patient's side is transmitted to the operator via the transmitting means on the patient's side unless the operator operates the switch on the patient's side. Since the information is transmitted to the receiving means on the side, the operator can listen to it, which allows the operator to infer the patient's psychological state and give appropriate instructions to reduce the patient's psychological burden. It is possible to provide a medical diagnostic device having excellent features such as:
