Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a posture display device that visually displays a detected posture based on posture information from a posture detection device.

[Prior Art] Conventionally, when monitoring a patient's posture, etc. in a hospital, an expensive television camera is used to photograph the patient, and the photograph is displayed on a television camera monitor device. For this reason, especially in dark places, expensive infrared television cameras had to be used.

In addition, in cases of ischemic heart disease such as angina pectoris or myocardial infarction, ST-T changes on the electrocardiogram can also occur due to changes in the subject's body position, so judgments cannot be made based solely on the electrocardiogram. Changes in body position must always be considered. Therefore, for accurate diagnosis, it is necessary to constantly monitor the patient's body position, and the patient is constantly monitored by a television camera. As a result, the patient may feel uncomfortable or intimidated. Furthermore, it was difficult to determine the posture when the subject was covered with a blanket, futon, etc. Therefore, in Japanese Patent Application Nos. 58-132560 to 132563, the inventor of the present application proposed a posture detection device and its detection circuit that are small, inexpensive and capable of very effectively detecting all postures including the body position of a patient. However, there is no means to effectively display the attitude information from this attitude detection device, and the attitude must be determined based on the signal level.
It becomes difficult to decipher.

[Object] The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a posture display device that can visually grasp the posture and is small and inexpensively constructed.

Another object of the present invention is to provide a biosignal display area for displaying biosignals such as an electrocardiogram monitoring monitor and a posture display area for visually displaying posture, and display them in association with each other. The purpose of this invention is to propose a posture display device that enables quick and accurate diagnosis.

[Example] An example of the present invention will be described below with reference to the drawings.

FIG. 1A is a block diagram showing the configuration of an attitude detection and attitude display device system according to the present invention, and 1 in the figure shows an attitude detection device such as that described in detail in Japanese Patent Application Nos. 58-132560 to 132563 mentioned above. , 2 is a recording tape recorder that records the attitude information detected by the attitude detection device 1, 3 is a reproduction tape recorder, 4 is an attitude demodulator that demodulates the attitude information from the reproduction tape recorder 3, and 5 is an attitude demodulator. 4 is an attitude display driver for displaying the attitude information demodulated on an attitude display device, and 6 is an attitude display device that displays an attitude state based on a drive signal of the attitude display driver.

The posture information detected by the posture detecting device 1 in this manner is recorded on the tape recorder, reproduced and demodulated, and displayed on the posture display device 6. By simultaneously recording electrocardiogram information from, for example, an electrocardiograph on this tape recorder, biological information corresponding to posture information can be easily obtained, and by displaying both in close proximity or on the same screen, appropriate diagnosis can be made. can be lowered. Here, we have shown an example in which the attitude information is recorded on a tape recorder, but instead of the tape recorder, a telemeter is used to transmit and receive the attitude information, and the attitude information is sent to the attitude demodulator 4.

An example of this is shown in FIG. 1B.

Here, a telemeter transmitting section 7 is used in place of the recording tape recorder 2 of FIG. 1A, and a telemeter receiving section 8 is used in place of the reproducing tape recorder 3. By doing so, the posture can be displayed on the posture display device 6 located at a remote location from the posture detection device 1.

Of course, if the locations are not remote, the two may be directly connected via a signal line.

This attitude detection device 1 is disclosed in, for example, Japanese Patent Application No. 58-132560.
By using the No. 1 posture detection device, it is small, inexpensive, and can be used even in dark places to detect blankets, etc. when a patient is sleeping.
The posture detection device can accurately detect the posture even when the patient is covered with a futon or the like, and does not give an unnecessary feeling of intimidation to the patient.

Next, FIG. 2 shows a display pattern of the attitude display device 6 using liquid crystal according to an embodiment of the present invention.

In FIG. 2, A ₁ to _{A 8} are display pattern parts indicating the nose, B ₁ to _{B 8} are display pattern parts indicating the ears,
C ₁ to _{C 8} are display pattern portions showing the eyes, D is a display pattern portion showing the head, and E ₁ to _{E 3} are display pattern portions showing the state of the upper body of the human body. The cuts in the circumference of the head display pattern part of this liquid crystal posture display device are the lead wire openings for driving the liquid crystal display parts of the eye display pattern parts _C1 to _C8 and the upper body display pattern parts _E1 to _E3 . be.

The display pattern of the posture display device 6 when the user is sleeping will be described with reference to FIGS. 3A to 3H, and the display pattern when the upper body is awake will be described with reference to FIGS. 4A to C.

Figure A in Figure 3 shows the patient sleeping facing directly upward. Figure B shows the patient moved 45 degrees to the right from Figure A, that is, lying on the right side at an upward angle of 45 degrees. Figure C shows the state where it is right sideways, and Figure D shows the state rotated 45 degrees further to the right than Figure C. Diagram E shows the patient lying prone, Diagram F shows the patient lying on the left side at a downward angle of 45 degrees, Diagram G shows the patient lying directly on the left side, and Diagram H shows the patient lying on the left side at an upward angle of 45 degrees. To the right of figure H
When rotated 45 degrees (upwards), it will point directly upwards as shown in Figure A.

As described above, as can be seen from the explanation of figures A to H in FIG. 3, the rotational movement and state during sleeping can be visually known at any time.

Next, the state where the upper body is standing up (including the case where the person is standing on both legs) will be explained with reference to FIG.

4A shows a state in which the upper body is standing up and bent forward (including a state of bowing, etc.). Only _E1 of the display pattern shown in FIG. 2 is displayed. Figure B shows a state in which the upper body maintains an almost upright posture, and only display pattern _E2 is displayed. Next, Figure C shows the normal state in which the upper body is arched, and the display pattern is only E ₃ .

The correspondence between display pattern parts and postures in the above case is shown below.

When applied to AND gate IC1, the output of IC1 turns on, displays the A1 pattern, and
It is input to each OR gate of IC12, IC16, IC23, IC24, and B3, B7, C1, C8,
0 display pattern is displayed, and the overall pattern shown in FIG. 3A is controlled.

As explained above, by visually displaying the posture information detected by the posture detection device 1 on the liquid crystal display, it is possible to create a small and inexpensive posture display device for patients, etc., and it can be easily attached to various measuring instruments. It is also possible to incorporate

By arranging this posture display device close to the monitor CRT screen of the electrocardiogram monitor device, a patient monitoring device is realized that can extremely easily compare and monitor the electrocardiogram waveform and the patient's posture (body position). An example of this patient monitoring device is shown in FIG. In the figure, 61 is a CRT screen that displays an electrocardiogram waveform, 62 is an example of patient posture display by the posture display device of this embodiment, and 63 is a patient name display section. Here, both the electrocardiogram waveform and posture display correspond in time.

Furthermore, the attitude display device of this embodiment is not limited to displaying a display pattern using a liquid crystal display;
The present invention can be applied to anything that has a display means that can display a display pattern.

FIG. 7 shows a display example when the posture display pattern 65 is displayed together with the electrocardiogram waveform display 64 on the waveform display CRT screen 60 of the electrocardiogram monitor device.

In this case, a display pattern instruction signal (corresponding to S1 to S11 in FIG. 1) from the posture demodulator 4 is given to, for example, a microprocessor (CPU) of the control section of the electrocardiogram monitor device or the CRT display control section,
It can be converted into a display pattern under the control of a microprocessor (CPU) and displayed on a CRT screen. The display pattern in this case can be easily displayed by storing it in a ROM or the like.

In this way, the posture corresponding to the biological signal is placed close to the
Alternatively, by displaying them on the same screen, it is extremely easy to determine the correspondence between the two and make an accurate diagnosis.

The measurement of such biosignals and the configuration of the biosignal display section are known and can be used as they are, so a description thereof will be omitted.

In the above description, S1 to S11 have been explained as posture information as an example, but it goes without saying that even if the posture information is code information or an analog signal, it is only necessary to convert it into the display pattern of this embodiment.

As explained above, according to this embodiment, the posture of the living body detected by the posture detection device 1 is combined with the head contour figure and the figures representing the nose position, the eye position, and the ear position at that time, so that the posture can be determined by By displaying the figure as a head with a nose and eyes, it is possible to easily recognize the subject's posture just by looking at the display.

Additionally, by displaying a head figure when the subject is in a sleeping position and a figure showing the inclination of the upper body when the subject is in an upright position, it is possible to visually display the postural position, including the inclination of the body, in real time. . Therefore, the subject's posture can be easily recognized just by looking at the display.

In other words, there is no need to analyze and interpret some kind of posture position display that represents the subject's posture position, as in the past, and then to specifically recognize the posture of the subject. The location of the subject can be easily recognized from

Further, according to this embodiment, the posture of the subject can be displayed in a small display area. For example, when displaying the measurement results of biological information measured by a biological signal measuring device, the posture of the subject can be displayed at the same time according to the posture at the time of measurement. Can be displayed visually. As a result, when analyzing the measurement results of biological signals, it is possible to judge the posture at the time, making it possible to make a quick and accurate diagnosis, especially when there is a correlation between the subject's posture and the measurement results such as electrocardiogram information. We can provide equipment that can be lowered.

[Effects of the Invention] As explained above, according to the present invention, all postures other than the patient's body position can be visually perceived. It can also be incorporated into the display section of other measuring instruments, etc.
By displaying the measurement results at the same time, it is possible to provide a posture display device that can reliably and easily grasp the posture and perform accurate diagnosis.
