BRIEF SUMMARY
BACKGROUND
The present invention concerns the improvement of a display device which displays data necessary for diagnosis and treatment in a medical diagnosis and treatment system.
Various types of medical diagnosis and treatment systems are provided with a display unit which is composed of monochrome display elements such as LEDs; for example, in the case of the pulse oximeter, display is performed in different modes, so that if the measured oxygen saturation level of the patient is normal, the display element is continuously illuminated while the measured value is displayed, and if it deviates from the normal range, the measured value is displayed while the display element flashes. Also, when the settings of the normal range are changed, the inputted setting values are displayed, but since these values are either steadily illuminated or flash, it is difficult to distinguish them clearly from the display when the values are normal or abnormal, resulting in the problem that the possibility of mistaken reading is high.
SUMMARY OF THE INVENTION
The present invention was developed in light of these problems, and has the purpose of offering a display device for a medical diagnosis and treatment system which allows the confirmation of contents or status to be displayed in accordance with these contents or status.
The present invention offers a medical diagnosis and treatment system display device which is provided with a multicolor display unit by which display can be performed in at least 2 colors and a control unit which along with determining whether display is to be performed by continuous illumination or by flashing, in accordance with the diagnostic or therapeutic data to be displayed, displays the diagnostic or therapeutic data by driving the aforesaid multicolor display unit.
By means of the present invention, multiple types of data can be displayed in accordance with the type of color used in a continuous illumination mode, and by adding flashing to this the amount of data which can be displayed is doubled, so that various types of data can be displayed in respectively differing modes. For example, when the multicolor display unit consists of 2 colors, by the combination of display color and steady illumination or flashing display can be performed in 4 modes, so that the 3 statuses of normal and abnormal diagnostic and therapeutic data and setting adjustment values can be easily displayed in differing display modes.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a block diagram of the medical diagnosis and treatment system provided with a display device in accordance with one working example of the present invention.
FIG. 2 is a diagram showing the configuration of the display unit of this working example.
FIG. 3 is a diagram of the control circuit in this working example.
FIGS. 4(a) and 4(b) are flow charts of the operating sequence in this working example.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The working example shown in the figures is next explained. FIG. 1 is a block diagram of the medical diagnosis and treatment system provided with a display device of the working example, FIG. 2 is a diagram showing an example of the configuration of the display device, FIG. 3 is a diagram of the control circuit, and FIG. 4 is a flow chart of the operating sequence. The present invention is not limited to the pulse oximeter described above, and can be applied to various types of medical diagnosis and treatment systems. Also, a microcomputer is used in the working example, but the control unit can be constituted so as not to use a microcomputer.
In FIG. 1, the symbol (1) indicates the multicolor display unit, which is composed of a display device (1a) and a display element drive circuit (1b), the symbol (2) indicates the control unit, which is composed of the microcomputer (2a), external interface (2b), speaker drive circuit (2c), watchdog circuit (2d), etc., (2e) is the CPU of the microcomputer (2a), and the control unit (2) performs various control operations such as digital communication with the dis
