(b) Conventional technology With the development of medical science in recent years, surgeries have been performed on important organs such as the brain and heart. The surgical procedures are also becoming more complex. Along with this.

Even small changes in the patient's condition or the state of his organs have a large impact on the outcome of the surgery, so it is important to constantly monitor these conditions in order to proceed with the surgery.

On the other hand, it is also important to constantly monitor the condition of critically ill patients in intensive care units where various devices are used to treat them. by the way.

In these conventional systems, data for understanding the patient's condition is displayed on devices installed near an operating table or treatment table, or on these terminal devices.

(c) Problems to be solved by the invention In conventional treatment systems, data for emulating conditions such as the condition of the patient and the state of organs is not available.

If necessary, as it is displayed on the equipment installed near the patient's board and its terminal equipment.

Doctors and supervisors should take their eyes off the area being treated.

These data had to be read, which made treatment time-consuming and caused inconveniences such as overlooking the display on the monitor equipment when focusing only on the treatment area, and delay in noticing changes in condition. .

Therefore, it is an object of the present invention to provide a monitoring device that does not require doctors and others to take their eyes off the treatment site.

2) Means for Solving the Problems The present invention has been made in view of the above, and it is possible to use a head-up display to collect essential data representing the condition of a patient and the state of organs such as organs. The treatment area or the entire patient is displayed within the field of view of the doctor or supervisor who is gazing at the patient.

In other words, 1 the present invention includes an input section for inputting medical information, a conversion section for converting the information input to the input section into an image @, and a display image based on the image signal converted by the conversion section. To provide a medical head-up display comprising a display device and a combiner that allows display light from the display device to enter the front field of view of a viewer such as a doctor who performs treatment such as surgery or monitors a critically ill patient.

Here, medical information includes, for example, electrocardiograms, blood pressure values, electroencephalograms, breathing air conditions (oxygen concentration and respiratory rate), but the present invention is not limited to these; Contains all information necessary for treatment.

In addition, one display device is one such as a liquid crystal display, CRT,
This includes fluorescent display tubes, etc. ,Furthermore, the combiner is.

It is disposed in a position that does not obstruct treatment or monitoring by a doctor, etc., and is preferably made of a material that allows the patient to see through the treatment area or the entire patient, such as transparent glass or transparent plastic.

Although there are various possible positions for displaying medical information, it is particularly preferable to place it in a position where it can be seen overlapping the affected area of the patient, the area targeted for treatment, etc. Display the outline line,
This can be achieved by displaying this during the initial positioning of the device prior to treatment and adjusting the combiner so that the patient's body can be seen superimposed on it.

(e) Effect: By using the present invention, doctors, etc. can know various medical information that is being monitored while keeping their eyes on the patient or the patient's body parts during treatment and monitoring, and can administer appropriate treatment to the patient without delay. be able to.

Furthermore, changes in the patient's condition expressed as information can be surely understood, and the treatment can be avoided.Examples The present invention will be explained according to the embodiments shown in the following nine drawings. .

FIG. 1 shows the configuration of a medical head-up display according to the present invention. From terminals into which various information is input (for example, electrocardiogram input terminal (1-), blood pressure value input terminal (1-2), electroencephalogram human power terminal (1-3), respiratory air condition input terminal (1-4), etc.) These information entered.

The symbol generator (SO) converts it into an image signal and sends it to the liquid crystal drive circuit (LA). Further, as a result, a display image is projected on the liquid crystal panels (I, C) connected to the liquid crystal drive circuit (LA). A high-intensity bank light (LL) is attached to this liquid crystal spring (LC) K, which passes through the liquid crystal panel (LC) and emits as display light (LR).

This display light (LR) is transmitted through a lens (t, 1, L2) so that the position of the virtual image (distance to the virtual image when viewed from the doctor's eyes (B)) is approximately the same as the patient's treatment area. It is collimated and emitted from the head-up display body■. After that, the 1 display light (LH) f'i is reflected by the combiner glass (Q) composed of a half mirror and reaches the eyes of the treating doctor (smell).By being collimated in this way, the 1 display image is The patient's body appears to appear directly and undistorted on itself.

Further, FIG. 2 shows a general outline of the installation of the head-up display of the present invention in a surgical procedure. Patient ■ is placed on the operating table α) and is ready for treatment. The treating doctor (DC) stands next to the operating table.

The head-up display body is made of combiner glass (
It has an integral structure with C3 and is suspended from the ceiling (F'). In addition, a lighting device (PL) is installed on the ceiling ( ) to illuminate the treatment area.
), the treatment area is covered with a combiner glass (C) when proceeding with the treatment.
), it is possible to know various data indicating the patient's condition at any time. Figure 3 shows an example of the display as seen from the doctor's eyes. This is, for example, a display of the reference contour line of the body. (BL) is displayed during initial positioning before treatment.

By adjusting the combiner glass (C) so that the patient's body can be seen superimposed on this.

For example, the electrocardiogram (HG) is displayed almost near the heart, and the expiratory oxygen concentration and breath view (BO) are displayed almost near the lungs. In this way, it will be easier for the doctor to understand the data showing the patient's condition, and to prevent misidentification of the data, the head-up display shown in the example will be displayed even during treatment. It may have a structure that allows it to be stored in a state where it is pulled up to the top when not in use. In addition, a CCD camera (CM) for recording the state of the surgery may be integrated with the Hend 7Sop Display main unit, and in this case, the video signal from the camera (CM) is
It is also possible to record the two-peak signals created for display together.

Note that the configuration of one head-up display is not limited to that shown in the drawings; for example, it may be structured such that a head-up display body (1-D) can be accommodated on an operating table (Tl). This can also be done using other display devices such as CRT or fluorescent display.

It goes without saying that there are various variations in the content of the display and the arrangement of the display image 1, the method of configuring the equipment, its shape, etc., according to the scope of the claims. Although an example in which a doctor performs treatment using the display is shown, the present device can also be used for cases other than one surgery, and may also be used by someone other than a doctor.
