Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data input device for inputting data, and more particularly to a data input device suitable for inputting measurement data having a temporal correlation.

[0002]

2. Description of the Related Art In a medical database or the like, data such as body temperature, blood pressure, pulse, and respiratory rate are measured at predetermined time intervals, and the measured data is input using a terminal device such as a data input device. Things have been done. Such measurement data usually does not change significantly and has a strong temporal correlation. In the conventional data input device, when inputting this kind of measurement data, a numerical value is directly input from a keyboard. Further, in a tablet device in which a tablet and a display are integrated, a pen input data input device that inputs data by pen touch with a stylus displays a predetermined numerical value and counts up the numerical value with the pen touch or You are counting down and setting the value to enter.

[0003]

However, in the former method of the above-mentioned conventional input operations, numerical values are input digit by digit using the keyboard, and therefore it is easy to input an incorrect numerical value due to an error in key input operation. Moreover, the influence of mistakes is great. On the other hand, in the latter input method, the operation of counting up or down the numerical value is complicated, and the operability of data input is difficult.

The present invention has been made in order to solve such a problem, and it is easy to input data such as measured values, the number of input errors is small, and the influence of input errors is also small. It is an object of the present invention to provide an extremely small data input device.

[0005]

A data input device according to the present invention changes a range of data displayed on the display unit according to a display change instruction and a display unit for displaying a plurality of continuous data within a certain range. The display range changing means, the input means for specifying one of the data displayed on the display means, and the data processing means for processing the data specified by this means are provided.

The display range changing means may shift the range of the data displayed on the display means by one data or may shift the display range by the display range.
It may be displaced in the middle range.

If the data is measured data,
It is desirable that the display means displays a plurality of continuous data within a certain range centered on the previously input measurement data. Further, the display means may display different data ranges for a plurality of measurement targets.

[0008]

According to the present invention, since a plurality of continuous data are displayed in a fixed range and one of the displayed ranges is specified to input the data, the data can be input. The input operation is an operation of selecting one of some data. For this reason,
Input mistakes are prevented and the input operation becomes easy.

It is possible to display and select all data that may be input as data, but in this case, desired data is selected from a large number of data. Takes time. In this respect, according to the present invention, since the data is displayed only in a certain range, the data can be easily selected. Furthermore, even if you specify a position different from the data that should be entered, the entered data is part of the limited range, so there is no mistake that the most significant digit is significantly different. It is possible to suppress an error that does not occur and causes almost no problem.

When selecting data not displayed in the above range, the display range may be changed by the display range changing means. In this case, the range of displayed data is shifted by n data. However, if the value of n is set to a large value, desired data can be searched for with a small number of display changing operations. The selection operation becomes much easier than the conventional method of changing the numerical value.

Further, since the measurement data has a high temporal correlation, if the data of a certain range centering on the previous measurement value is displayed, the possibility that the next measurement data will be included in the display range becomes extremely high. Data can be selected with almost no display change operation. Further, by displaying the range according to each measurement target, the probability that the measurement data is included in the display range can be increased similarly to the above, and it becomes possible to select the data with almost no display change operation. .

And are displayed. The scroll instruction units 45 and 46 and the numerical value selection unit 47 are provided corresponding to five types of measurement data of body temperature, blood pressure (H), blood pressure (L), pulse and respiration rate, respectively. Eleven continuous data such as “35.5”, “35,6”, ..., “36.5” are displayed in the numerical value selection section 47 corresponding to each measurement data. When the stylus 4 makes a pen touch on the scroll instruction parts 45, 46,
The display range of the 11 pieces of data is changed. In this case, the display range may be scrolled by 1 data, 11 data, or an intermediate range. When one of the data in the numerical value selection section 47 is touched with the stylus 4, the data is input data 4
Registered as 4.

FIG. 5 is a diagram showing data for determining the display range stored in the memory 12, where v (0) to v (4) are
The variables dv (0) to dv (4) in which the numerical values displayed at the top of the numerical value selection unit 47 corresponding to the body temperature, blood pressure (H), blood pressure (L), pulse, and respiratory rate are respectively stored are The size of one step of the display data of the numerical value selection unit 47 corresponding to the body temperature, the blood pressure (H), the blood pressure (L), the pulse, and the respiratory rate is a variable stored. These variables are stored in the memory 12 and are changed when the display range is changed.

FIG. 6 is a flow chart showing the processing for displaying the numerical value selection section 47. As shown in FIG. 4, the start coordinate value of the numerical value selection unit 47 in the x-axis direction is set to x0, y.
The starting coordinate value in the axial direction is y0, the display step length in the x-axis direction is dx, and the display step length in the y-axis direction is dy. First, variables j and k are reset (S1, S2), and x0 is set to x0.
By substituting + j · dx and substituting y0 + k · dy for y, the position to be displayed is determined (S3). Then, v (j) -k · dv (j) is displayed at the position (x, y) (S4). Actually, (x, y) of the VRAM 18
The above calculated value is stored in the address corresponding to. This S
When the processes of S3 and S4 are sequentially executed while changing j from 0 to 4 and k from 1 to 10 for each j (S5 to S8), the numerical value selection unit 47 displays all the numerical values to be displayed. Will be displayed.

Next, the processing when a pen touch on the scroll instruction sections 45, 46 or the numerical value selection section 47 is detected will be described with reference to the flowchart of FIG. First, C
When the PU 11 inputs the x, y coordinate values via the position detection circuit 24 (S11) and recognizes from the x, y coordinate values that it is a pen touch on the scroll instruction units 45, 46 or the numerical value selection unit 47. (S12), it is determined from the x coordinate value whether the input corresponds to body temperature, blood pressure (H), blood pressure (L), pulse, or respiration rate (S13). = 0, i = 1 if blood pressure (H), i = 2 if blood pressure (L), i = 3 if pulse, i = 4 if breathing rate Are respectively substituted (S14a to S14e).

Next, from the y coordinate value, the scroll instruction section 4
5 (▲) is touched with the pen, or scroll instruction unit 4
It is determined whether it is a pen touch on 6 (▼) or a pen touch on the numerical value selection unit 47 (S15). If the scroll instruction unit 45 is touched with the pen, the variable v (i) is changed to v (i) + n · dv (i) (S1).
6) If the scroll instruction unit 46 is a pen touch, the variable v (i) is changed to v (i) -n · dv (i) (S17). Note that n is a value that determines the step range at the time of scrolling, when 1 is set, scrolling for one data is performed, and when 11 is set, 1 is set.
One data, that is, the display range is scrolled. For example, the scroll instruction unit 4 corresponding to the body temperature
When the scroll instructing unit 45 is touched with the pen when the numbers 5 and 46 and the numerical value selecting unit 47 are displayed as shown in FIG.
It is scrolled by the amount of data and becomes as shown in FIG.

On the other hand, as a result of the y-coordinate determination, the numerical value selection unit 47
If it is recognized as a pen touch to v (i)
-[(Y-y0) / rounded value of dy] xdv (i) is processed as input data (S18). Here, for example, when the body temperature should be entered as "36.0", even if the user mistakenly touches the adjacent "36.1" with the pen, the error is 0.1 degrees, which may cause a serious measurement error. There is no.

If the process of replacing the variable v (i) with the input data + [5.dv (i)] is performed when the input data is obtained in S18, it is indicated by A in FIG. 9 at the next measurement. As described above, the range centering on the previous input data is displayed. Considering that the probability that the measurement data at the time of the next measurement and the measurement data at the time of the previous measurement will be significantly different is extremely low, by performing such a display,
The probability of scrolling the display range in the next measurement is also extremely low, which makes it easier to select measurement data.

Further, if the variables v (0) to v (4) described above are stored for each patient and the display range is made different for each patient, the scroll due to the difference in the measurement data range between patients is performed. Since the occurrence of is eliminated, the selection operation becomes easier. In this case, for example, in the variables v (0) to v (4), the index indicating the number of the numerical value may be stored as shown in FIG. 10 without storing the data as it is. . In this way, it is possible to reduce the storage capacity when storing the variables v (0) to v (4) in association with each of a large number of patients.

The present invention is not limited to the above embodiment. In the above embodiment, medical measurement data is taken as an example, but it goes without saying that it can be applied to other data input. Also, as a tablet device,
In addition to the above-mentioned ones, it can be applied to all types of tablet devices such as an electrostatic coupling system, an electrode contact system, a piezoelectric effect system, and a conductive sheet system. Furthermore, the present invention can be applied to a device in which a display and a tablet are separately configured, and can also be applied to a data input device connected to a host computer by a cable.

[0026]

As described above, according to the present invention, a plurality of continuous data are displayed in a certain range, and one of the limited ranges is specified to input the data. Thus, the operation of inputting data is an operation of selecting one of several data, and the selection width is narrow, so that an input error can be prevented and the input operation becomes easy.
