DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an audiometer.
For example, the present invention is suitably applied to an audiometer used in a medical institution that performs a mass examination.

[0002]

2. Description of the Related Art In recent years, medical institutions such as hospitals and medical examination centers have introduced data management using computers. For this reason, in each medical testing device used in such a medical institution, when the test result is transferred to the computer, the identification number of each subject (hereinafter, referred to as “identification number”) that can identify which subject the data belongs to. This is called the ID number)
There is a demand for the addition of a function that allows the user to input a password.

[0003]

However, many medical examination devices including an audiometer do not have a key for inputting numbers, such as a numeric keypad, on an operation panel, for example. If a new numeric keypad is provided on the operation panel, the external shape of the device becomes large, which is disadvantageous in terms of cost. For this reason, it is conceivable to add a function that allows an ID number to be input to these medical test devices by using a conventional key so that a number can be input. It is desirable that the keys for inputting be arranged in a concentrated manner on the operation panel, and there is a problem that operability is hindered simply by using a conventional key together with a key for appropriately inputting a number.

Here, an audiometer generally has an operation switch (hereinafter, referred to as a frequency switch) for switching the frequency of a test sound emitted from a receiver.
Since these frequency switches are switches having the same function, they are concentrated on the operation panel. Therefore, for example, when adding a function that allows the ID number to be input to the audiometer, if the frequency switch is used in combination with a key for inputting a numerical value, the cost will not increase and the operability will be improved. Therefore, it is considered that a function of efficiently inputting numerical values can be added as a whole.

The present invention has been made in view of the above points, and is intended to add a function of efficiently inputting numerical values to an audiometer.

[0006]

In order to solve this problem, the present invention has a plurality of controls 40 to 50,
The operated controls 40 to 50 of the respective controls 40 to 50
In an audiometer that emits a test sound of a predetermined frequency corresponding to the above from the receivers 11 to 13, a plurality of operators 40 to
By operating the device 50, the identification information and / or date information of the subject is input numerically.

[0007]

The identification information of the subject and / or the date information is input by operating a plurality of operators 40 to 50, so that the identification information can be input using the existing operators 40 to 50. It can be entered and thus has no significant cost disadvantages compared to conventional audiometers.

Generally, the plurality of operators 40 to 50
Are arranged in a predetermined position, the identification information and / or date information of the subject can be input numerically with good operability.

It is sent to the circuit 6.

The variable attenuator 5 attenuates the sine wave signal S3 as required based on the control signal S2B supplied from the CPU 3, and sends it to the switch circuit 7 as an attenuated sine wave signal S4. The switch circuit 7 sequentially opens and closes the switches based on a control signal S2C supplied from the CPU 3, and sends out an attenuated sine wave signal S4 to the receiver switch 9 via the amplifier 8 when the switches are closed. The handset switching unit 9 outputs the attenuated sine wave signal S4 based on the control signal S2D supplied from the CPU 3 to the first or second air conduction handset 10, 11 or the bone conduction handset 1

That is, in the audiometer 1, for example, when the power is turned on or the standard pure tone switch 31 is pressed, the CPU 3 selects the program of the standard pure tone inspection mode.

In this state, the CPU 3 operates the frequency switches 40, 41, 42, 4 provided on the operation panel 2.
When one switch is pressed from among 3, 44, 45, 46, 47, 48, 49, and 50, a corresponding control signal S2A is output to output a corresponding one of the frequency switches 40 to 50 that have been pressed. Frequency (125 [Hz], 250 [Hz], 500 [Hz], 800 [H

The hearing level and frequency of the test sound to be emitted can be changed, and thus various tests using the standard pure tone test method can be performed on the subject. Further, when the threshold switch 60 disposed on the operation panel 2 is pressed in the standard pure tone test mode, the CPU 3 sets the value corresponding to the dial scale of the hearing level adjustment dial 51 at this time by the subject. It is recorded in a memory (not shown) as a minimum hearing level value (threshold value) that can be heard. This allows the audiometer 1 to sequentially record the threshold value of the subject for each frequency as data.

Further, when the CPU 3 confirms that the ID number input mode has been selected in step SP3 (that is, the ID number input switch 80 has been pressed), the CPU 3 proceeds to step SP20 and selects one of the function switches 30. It is determined whether 31 to 34, 80 have been pressed. If a negative result is obtained in step SP20, the CPU 3 proceeds to step SP21 and waits for the input of a numerical value by the pressing operation of the frequency switches 40 to 50. When the frequency switches 40 to 50 are pressed, the CPU 3 proceeds to step SP22. Numerical values corresponding to the pressed frequency switches 40 to 50 are stored.

If a negative result is obtained at 0, the process proceeds to step SP23 to determine which of the functional switches 30 the switches 31 to 34, 80 are pressed. If the CPU 3 determines that the function switch 30 pressed in step SP23 is the ID number input switch 80, the CPU 3 proceeds to step SP21.

On the other hand, if the CPU 3 determines that the pressed function switch 30 is a switch 31-34 other than the ID number input switch 80, the CPU 3 proceeds to step SP.
The routine proceeds to step 24, where the standard pure tone inspection mode is always selected irrespective of the function switch 30 which has been pressed, and thereafter the process returns to step SP3.

(1-8) Operation of First Embodiment In the above configuration, the CPU 3 sets the ID number input switch 8
When the frequency switches 40 to 49 are pressed after the 0 is pressed, the operated frequency switches 40 to 49 are pressed.
Numerical values corresponding to 49 are sequentially stored, and thereafter,
When the ID number input switch 80 is pressed, the input numerical values are collectively stored in the memory as ID numbers. Thereby, in the audiometer 1, the frequency switches 40 to
Numerical values can be sequentially input by pressing the button 49. In this case, in the audiometer 1, since the existing frequency switches 40 to 50 are used as the numerical value input means, it is more cost effective than the case where the ten keys are newly arranged on the operation panel 2 as described above. It is.

In the audiometer 1, since the existing frequency switches 40 to 50 are used as numerical value input means, the operability is not hindered as described above.

(1-9) Effects of the First Embodiment According to the above configuration, it is possible to input a numerical value by using the frequency switches 40 to 50.
A function of efficiently inputting numerical values can be added to the audiometer.

(2) Second Embodiment FIGS. 5 and 6 in which parts corresponding to those in FIGS. 1 and 2 are denoted by the same reference numerals show an audiometer 90 according to a second embodiment, and an operation panel 91 has an ID number input switch. The configuration is almost the same as that of the audiometer 1 of the first embodiment, except that the 80 (FIG. 2) is not provided and the input method of the ID number is different. That is, in the audiometer 90, by sequentially pressing the frequency switches 40 to 50 while pressing the all switch 65 disposed on the operation panel 91, the numerical value corresponding to the pressed frequency switches 40 to 50 is assigned an ID number. Can be sequentially input.

For this reason, in the audiometer 90, the CPU 92 operates the operation switches 31 to 34, 40 to 50, 52, 53, 55, and 5 provided on the operation panel 91.
6, 60 to 63, 65, 66, and 70, each time the command signal S1 is supplied by the pressing operation, a predetermined ID number input determination mode program is sequentially executed to execute an operation command based on the command signal S1. Whether the switches 40 to 50 are pressed or not, and if the operation command is an operation command when the frequency switches 40 to 50 are pressed, the all switch 65 is pressed together. It is sequentially determined whether or not they are present.

The CPU 92 determines that the operation commands based on the command signal S1 are operating switches 31-34, 52, 53, 55, 56, 60-63, other than the frequency switches 40-50.
When it is confirmed that the operation commands 65, 66, and 70 are operation commands due to the pressing operation, or when the frequency switches 40 to 5
When it is confirmed that the all switch 65 has not been pressed together with 0, an operation command based on the command signal S1 is written into a command buffer memory (not shown). Thus, the CPU 92 thereafter returns to the program of each inspection mode, and thereafter reads out the operation commands from the command buffer memory and sequentially executes the operation commands, thereby executing the operation commands in the same manner as the audiometer 1 of the first embodiment. Standard pure tone inspection mode, SISI
Programs are sequentially processed in an inspection mode, an ABLB inspection mode, or a self-recording audio geometry inspection mode.

In practice, the CPU 92 selects and executes a program in each inspection mode according to the inspection processing procedure RT2 shown in FIG. In this case, the CPU 92 proceeds to step SP3.
1 to SP49 are processed in the same manner as steps SP1 to SP19 in the inspection processing procedure shown in FIG. 3 except that an operation command based on the command signal S1 is read out from the command buffer memory, and the contents are confirmed and then processed. Has been made. The CPU 92 also operates the operation switches 31 to 34, 40 to 50, 52, 53, 55, 56, and 6 disposed on the operation panel 91 during execution of the inspection processing procedure.
Each time 0 to 63, 65, 66, and 70 are operated, the process proceeds to the ID number input determination processing procedure RT3 shown in FIG.

In this case, when the ID number input determination processing procedure RT3 is started in step SP50, the CPU 92 determines in step SP51 whether or not the frequency switch 40 to 50 has been pressed. Further C
If the PU 92 obtains a negative result in step SP51, it proceeds to step SP52 and operates the operation switches 31 to 31.
4, 52, 53, 55, 56, 60 to 63, 65, 6
The operation command input by the pressing operation of steps 6 and 70 is written into the above-mentioned command buffer, and step SP53 is executed.
To return to the inspection processing procedure RT2. On the other hand, if a positive result is obtained in step SP51, the CPU 92 proceeds to step SP54 and determines whether or not the all switch 65 is being pressed together.

When the CPU 92 obtains a negative result in this step SP54 (that is, the frequency switch 40 to
(When the 50 is pressed and the all switch 65 is not pressed), the process proceeds to step SP55, and the operation command corresponding to the pressed frequency switches 40 to 50 is written in the above-mentioned command buffer memory. The process proceeds to step SP53 and returns to the inspection processing procedure RT2. On the other hand, if the CPU 92 obtains an affirmative result in step SP54 (that is, if the frequency switches 40 to 50 are pressed and the all switch 65 is pressed), the CPU 92 proceeds to step SP56 and presses the frequency pressed. Switch 40-50 8000
It is determined whether or not the frequency switch 50 corresponds to [Hz].

When the CPU 92 obtains a negative result in step SP56, it proceeds to step SP57 and sequentially stores numerical values corresponding to the pressed frequency switches 40 to 49 as ID numbers, and sends a control signal S2J to the operation panel 91. Then, the input numerical values are sequentially displayed on the display unit 57, and thereafter, the process proceeds to step SP53 and returns to the inspection processing procedure RT2. On the other hand, if the CPU 92 obtains a negative result in step SP56, it proceeds to step SP58 and deletes the numerical value of the least significant digit of the ID number stored at this time from the storage and controls the operation panel 91 at this time. After transmitting the signal S2J, the least significant digit among the numerals representing the ID numbers displayed on the display unit 57 is erased, and the process proceeds to step SP53 to return to the inspection processing procedure RT2.

According to the above configuration, for example, like the ID number input switch 80 of the audiometer 1 of the first embodiment,
There is no need to provide a dedicated switch for inputting an ID number, and thus a function capable of inputting numerical values to the audiometer more efficiently than in the first embodiment can be added.
