<Caliper settings>
The polygraph 100 of the present embodiment has a caliper function. The caliper function is executed by the main unit 200.

  FIG. 2 shows a configuration for realizing the caliper function. Operation signals obtained by key operations or mouse operations on the input device 10 are sent to the display control unit 201 and the line setting unit 202. The display control unit 201 changes the position of the cursor on the display 20 based on the operation signal.

  The line setting unit 202 sets a measurement start line, a measurement end line, and an intermediate line that serves both as a measurement start and a measurement end based on the operation signal. Each set measurement line is displayed on the display 20 via the display control unit 201. Further, information on each set measurement line is sent to the section length calculation unit 203.

  The section length calculation unit 203 calculates a section length between each measurement line. The calculated section length is displayed on the display 20 via the display control unit 201.

  FIG. 3 is a diagram illustrating an example of setting a measurement line according to the present embodiment. A waveform such as an intracardiac electrocardiogram is displayed on the display. In such a screen, first, when the left click button of the mouse 13 is held down, a measurement start line LS is displayed. Next, the measurement start line LS is set to the position by moving the measurement start line LS to a desired position while keeping the left click button pressed and releasing the left click button.

  Next, when the mouse 13 is moved to the left and right in that state, the measurement line moves in response to the movement, and the measurement line is moved to a desired position and the left click button of the mouse 13 is pressed while pressing the control key (Ctrl). The intermediate line L1 is set at that position. Next, when the mouse 13 is moved to the left and right in that state, the measurement line moves in response to the movement, and the measurement line is moved to a desired position and the left click button of the mouse 13 is pressed while pressing the control key (Ctrl). The intermediate line L2 is set at that position.

  Next, when the mouse 13 is moved to the left and right in that state, the measurement line moves in response to the movement, and the measurement line is moved to a desired position and the left click button of the mouse 13 is pressed to reach the measurement end line LE at that position. Is set.

  Here, the intermediate lines L1 and L2 are lines that serve as both measurement start and measurement end. The section length calculation unit 203 identifies the measurement start line LS, the measurement end line LE, and the intermediate lines L1 and L2 from the difference in setting operation, and sets the section length (50 ms) between the measurement start line LS and the intermediate line L1. ), A section length (25 ms) between the intermediate line L1 and the intermediate line L2, and a section length (40 ms) between the intermediate line L2 and the measurement end line LE are calculated. By providing the intermediate lines L1 and L2 that serve both as the measurement start and the measurement end, it is possible to easily realize a continuous caliper that can calculate and display the section length of the continuous sections.

  FIG. 4 is a diagram showing a comparative example with respect to the present embodiment. In order to perform the continuous caliper similar to the embodiment, first, the measurement start line LS1 and the measurement end line LE1 are set. Next, the measurement start line LS2 is set at the same position as the measurement end line LE1, and the measurement end line LE2 is set. Next, the measurement start line LS3 is set at the same position as the measurement end line LE2, and the measurement end line LE3 is set. Here, the operation of setting the measurement start line LS2 at the same position as the measurement end line LE1 and the operation of setting the measurement start line LS3 at the same position as the measurement end line LE2 are actually difficult. In addition, the number of operations required to set the measurement line is increased compared to the embodiment, which takes time. On the other hand, in the present embodiment, by providing the intermediate lines L1 and L2 that are used for both the measurement start and the measurement end, it is possible to reduce the trouble of setting a continuous caliper.

FIG. 5 is a diagram illustrating a state in which the measurement line of the present embodiment is set on the display 20 on which the electrocardiogram is displayed. The waveforms in FIG. 5 are the surface electrocardiogram (II, V ₁ ) and intracardiac electrocardiogram (HRA _1-2 ) when a single extra-phase stimulus is applied from the right ventricular apex during the tachycardia at the timing of the refractory period of the His bundle. , HBE _5-6 ,..., RVA _3-4 , RVA _1-2 ).

Continuous caliper is performed by setting intermediate lines L1 to L6 in addition to the measurement start line LS and the measurement end line LE at the peak position of the HRA _1-2 . By performing this continuous caliper, it can be seen at a glance that the section length (AA interval) sandwiching the stimulation spike by the extraventricular stimulation is shorter than that during tachycardia. Thereby, it can be judged that the chamber conduction is via the auxiliary conduction path.

  As described above, according to the present embodiment, in addition to the measurement start line LS and the measurement end line LE, the measurement start and measurement end of the section are combined between the measurement start line LS and the measurement end line LE. By setting the intermediate lines L1, L2,... To be performed and performing the continuous caliper, it is possible to set a measurement line that is convenient for measuring the section length, and to reduce the effort required to set the measurement line. It becomes like this.

  Note that the method of setting the measurement start line, the measurement end line, and the intermediate line shown in the above embodiment is a preferable example, and the operation assigned to each line setting is not limited to the above embodiment. However, it is preferable that the setting operation assigned to the setting for the intermediate line is obtained by adding a predetermined setting operation to the setting operation for the measurement start line or the measurement end line. That is, in the embodiment, an operation of pressing a control key in addition to the left click button, which is a setting operation of the measurement end line, is assigned to the setting operation of the intermediate line. By doing so, the intermediate line can be set by an operation similar to the setting operation of the measurement start line and the measurement end line, so that the intermediate line can be set by an operation that does not bother.

  In the above-described embodiment, the case where the measurement end line LE is set when the left click button of the mouse 13 is pressed after setting the intermediate lines L1 and L2 has been described. However, the measurement end line LE is set. The method is not limited to this, and the intermediate line may also serve as the measurement end line. For example, when the measurement end line LE is not set, the rearmost intermediate line (in the case of the embodiment, the intermediate lines L2 (FIG. 3) and L6 (FIG. 5)) may be the measurement end line. .

  In the above-described embodiment, the case where the present invention is applied to the polygraph 100 has been described. However, the present invention can be widely applied to biological information measuring apparatuses other than the polygraph 100.

  The above-described embodiments are merely examples of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed as being limited thereto. That is, the present invention can be implemented in various forms without departing from the gist or main features thereof.

  The present invention can be applied to a biological information measuring device having a caliper function.
