Then, for example, on the right side of the patient selection switch 63 (on a display screen following the switch)
By displaying the collected data from the patient and the processing data, the patient name and the collected data of the patient can be clearly associated and recognized.

In a general information processing apparatus, various instruction inputs and display of processing results accompanying the instruction inputs are executed in a time series, and the display results and the instruction inputs are frequently associated with each other. There is little need. As a result, when an instruction is input, only the input instruction guidance is displayed on the display screen, and the instruction input is performed. Thereafter, there is no problem in switching the display screen and displaying the result. For practical use, the display screen and the sensing area of the touch panel are matched, and the sensing area is set as wide as possible.

However, as described above, in the biological information processing apparatus, for example, it is frequently performed to analyze collected information from a patient, display the analysis result in real time, and constantly monitor the state of the patient. In such a case, if it is desired to see only the information of a specific patient in more detail, the current display state is temporarily stopped and the screen is completely shifted to the input guidance screen, and the patient state during that time cannot be grasped. Will be.

As described above, it is necessary to input a valid instruction while continuing to display and monitor the patient state. In such a case, by using the switch 63 of the present example, it is possible to promptly input an instruction without greatly changing the current display state. In this case, the display area of the processing result of the biological information is not narrowed.

As described above, according to the embodiment of the present invention, in addition to the first sensing area 51 functioning as a normal touch panel, the second sensing area 52 is provided via a certain non-sensing area 53. Since the display area is provided, for example, even when a processing result or the like is displayed on the display screen, the second sensing area can be allocated to, for example, an instruction input only without disturbing the display control. Therefore, as an example, this is assigned as a patient selection switch for selecting a patient, and the display screen area on the right side displays the collected biological information and the processed biological information from the patient, thereby associating with the display content on the display screen. This makes it possible to input an instruction very easily and reliably. For this reason, it is possible to reduce operation errors and the like, and to provide a highly reliable device with few malfunctions even in an emergency situation.

The patient plate 350 does not require any special computer operation or electronic device operation, and can be created by writing a patient name by handwriting or the like. Even if the patient bed is changed once the patient name plate is created, simply change the set position of the patient plate or insert the patient plate into the corresponding switch, and the patient name and display image can be easily displayed. Can be taken.

As described above, according to the present invention, in addition to the first sensing area which is also a display area of the processing result functioning as a normal touch panel, the second sensing area is provided on the side face of the first sensing area. Using a touch panel provided with the area 52, a switch to which a function corresponding to the display is assigned can be provided on a side surface of the display area of the processing result of the biological information, and even when the function of the switch is changed, It can be easily handled only by replacing the display plate displaying the function after the change.

For this reason, for example, even if the switch is used as a patient-specific switch and the display area on the side of the patient-specific switch is controlled to display the collected biological information and processing information from the patient, the display of the display area can be performed. Can be recognized very easily. In addition, even if the patient is moved and the collected information is displayed from a different device, the display plate displaying the patient name is moved together with the patient and locked on the side of the display area of the corresponding device. By doing so, even if there is a change in the display target,
Everyone can respond very easily.

Further, the display plate is merely required to be locked or held by the corresponding switch, and the change thereof is easy. Furthermore, this switch does not require any special switch contacts, but can be added by changing the specifications of the touch panel slightly.The contact input detection circuit of the switch is also compatible with the touch panel control circuit provided on the display surface. They can be shared and can be simplified. In other words, no special control circuit for the switch circuit is required at all, only a mechanism capable of pressing the touch panel at the switch contact point is sufficient, and there is no need to adjust the control circuit, and the occurrence of defects is greatly reduced. It can be reduced, and the reliability can be increased.
