Description

  The present invention relates to a biological information measuring device and system, for example, to a biological information measuring device and system such as an electrocardiograph which can be transported by a trolley.

  Conventionally, there is an electrocardiograph called multi-function electrocardiograph having an electrocardiogram analysis function in addition to the electrocardiogram measurement function. The multifunctional electrocardiograph has the electrocardiogram analysis function and can obtain the determination result on the spot where the electrocardiogram was measured, so it is used not only in hospitals but in various places such as health checkup. Furthermore, some multifunctional electrocardiographs have a function that can support an exercise stress test and an LP (Late Potential) test. Such a multifunctional electrocardiograph is described, for example, in Patent Documents 1 to 3 and the like.

  By the way, in the multi-function electrocardiograph, (1) insert one end of the power cord into the AC inlet of the electrocardiograph and then operate the AC while keeping the other end of the power cord plugged into an external AC outlet (for example, wall outlet) (2) Insert one end of the power cord into the AC inlet of the electrocardiograph and plug the other end of the power cord into an external AC outlet to charge the battery once and then operate the battery as a power source or any operation Is done.

  Therefore, in a multi-function electrocardiograph, at the time of AC operation and battery charging, it is necessary for a user who is a medical worker to insert a power cord into the AC inlet.

  In particular, multifunctional electrocardiographs generally consume more current than simple-type electrocardiographs because they are multifunctional, so the time that they can be driven by their own battery is short, and frequent use of power cords Charging or AC operation with the power cord plugged in is required. Therefore, the user was forced to frequently work to plug the power cord into the AC inlet, which was very troublesome.

Such a thing can occur widely in a living body information measuring device which can measure a plurality of living body information. For example, in a biological information monitor that measures and displays a plurality of biological information such as an electrocardiogram, blood pressure, SpO ₂ , a plurality of biological information are measured, and a display unit that displays a plurality of biological information as a measurement result Due to the increase in size, as with multi-function electrocardiographs, the battery can be driven by its own battery for a short time, requiring frequent charging with a power cord or AC operation with the power cord plugged in. The user was forced to work frequently, such as plugging the power cord into the AC inlet, which was very annoying.

  The present invention has been made in consideration of the above points, and provides a biological information measuring device and system that can eliminate the need for the user to insert and remove the power cord from the AC inlet.

  Before describing the embodiments of the present invention, the process leading to the present invention will be described first.

  The inventor of the present invention focused on the fact that biomedical information measuring devices such as multi-functional electrocardiographs and biomedical information monitors can generally be placed and transported on a dedicated trolley. That is, the medical information measuring apparatus for medical use is placed on the trolley and transported, and is placed together with the trolley at a convenient place in the room where the biological information is measured.

  Furthermore, the inventor has made it possible for the trolley and the biological information measuring device to prevent the biological information measuring device from falling out of the trolley and to align the recording paper (folded paper) sent to the recorder. It paid attention to the fact that the positioning engagement part which mounts and positions a living body information measuring device in a mounting position was provided. Then, it was considered that wireless power feeding from the trolley to the biological information measuring device can be suitably performed by effectively utilizing the existing positioning engagement portion.

  That is, one feature of the present invention is that the power receiving coil unit is provided in the biological information measuring apparatus and the power transmitting coil unit is provided in the trolley so that wireless power feeding can be performed from the trolley to the biological information measuring apparatus by electromagnetic induction. It is. Further, one feature of the present invention is that positioning of the power receiving coil unit and the power transmitting coil unit is performed by utilizing an existing positioning engagement portion.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing an appearance of a system according to the present embodiment. The present embodiment is an example in the case where the biological information measurement device mounted on the trolley 200 is a multi-function electrocardiograph (hereinafter simply referred to as "electrocardiograph") 100. The system 10 includes a multifunction electrocardiograph 100 and a trolley 200. The electrocardiograph 100 is mounted on the mounting table 210 of the trolley 200.

  The electrocardiograph 100 includes a display unit 110, a recorder unit 120, an operation unit 130, and the like. The electrocardiograph 100 measures a multilead electrocardiogram, such as a 12 lead electrocardiogram. The electrocardiogram measurement result and the electrocardiogram analysis result can be displayed on the display unit 110, and can be recorded on a recording sheet by the recorder unit 120. Further, the circuit board 150 (FIG. 2), the amplifier 160 (FIG. 2), etc. on which various circuits including an electrocardiogram measurement circuit, an electrocardiogram analysis circuit, and an image processing circuit are formed inside the housing 140 of the electrocardiograph 100 Is housed.

  Positioning and engaging portions 211 and 212 formed of screw holes are provided on the mounting table 210 of the trolley 200. Further, on the bottom of the electrocardiograph 100, a positioning engagement portion (not shown) made of a screw hole is provided. In practice, the screw holes in the bottom of the electrocardiograph 100 are provided in two of the four rubber legs provided to project from the bottom of the electrocardiograph 100, which are diagonally located. Then, the positions of the screw holes of the mounting table 210 and the screw holes of the electrocardiograph 100 are made to coincide with each other, and the electrocardiograph 100 can be positioned and fixed on the mounting table 210 by screwing in screws. In the example of the present embodiment, although the case where the screw hole is provided as the positioning engagement portion is described, the positioning engagement portion is not limited to the screw hole. For example, four engagement holes in which the four rubber legs of the electrocardiograph 100 are fitted are provided on the upper surface of the mounting table 210, and the four rubber legs and the four engagement holes are engaged with each other. The electrocardiograph 100 may be positioned at an upper predetermined position.

  Further, a sheet passing hole 213 is formed in the mounting table 210, and a recording sheet such as a folded sheet placed on the sheet table 250 is electrocardiographed from the bottom surface direction of the electrocardiograph 100 through the sheet passing hole 213. It is designed to be drawn into the recorder unit 120 of 100. The electrocardiograph 100 can also perform recording using roll paper stored in the recorder unit 120, in addition to recording using folded paper.

  Also, a cable passage hole 214 is formed at the rear end position of the mounting table 210, and a cable such as a communication cable connected to the electrocardiograph 100 is directed downward of the mounting table 210 via the cable passage hole 214. Pulled out.

  In addition to this, the trolley 200 is provided with a power cord 220. The power supply cord 220 may be one that can be inserted into and removed from the AC inlet of the trolley 200, or may be one that is fixedly pulled out from the trolley 200.

  In the mounting table 210, a power transmission coil unit 230 and a battery 240 are incorporated. In addition, although the power transmission coil unit 230 is always provided in the mounting base 210, the battery 240 may be incorporated not only in the mounting base 210 but in the lower part or pillar of the trolley 200, for example. The power from the power cord 220 is sent to the power transmission coil unit 230 and the battery 240.

  FIG. 2 is a schematic cross-sectional view showing an internal arrangement of the electrocardiograph 100 of the present embodiment.

  The circuit board 150, the amplifier 160, and the like are accommodated in the housing 140. On the surface side of the circuit board 150, a central processing unit (CPU) 151 that executes calculation parts of an electrocardiogram measurement circuit, an electrocardiogram analysis circuit, and an image processing circuit, a memory (not shown), and the like are mounted.

  Furthermore, the power receiving coil unit 170 is mounted on the back side of the circuit board 150. The power receiving coil unit 170 is supplied with power wirelessly from the power transmission coil unit 230 of the trolley 200 by electromagnetic induction. The power receiving coil unit 170 is electrically connected to the circuits on the circuit board 150, the amplifier 160, the display unit 110, the recorder unit 120, the battery 180, and the like. Thus, the electrocardiograph 100 can be directly operated by the power obtained by the power receiving coil unit 170, and the battery 180 can be charged by the power obtained by the power receiving coil unit 170.

  Further, in the present embodiment, the electrocardiogram measurement circuit, the electrocardiogram analysis circuit, and the image processing circuit are mounted on the front surface side of the circuit board 150, and the receiving coil unit 170 is mounted on the back surface side of the circuit board 150. The adverse effect on the electrocardiogram measurement circuit, the electrocardiogram analysis circuit and the image processing circuit due to the noise generated by the electromagnetic induction can be reduced.

  Incidentally, in practice, a drive circuit (not shown) for causing the power transmission coil unit 230 and the reception coil unit 170 to perform synchronous operation and the like is required. That is, each of the power transmission coil unit 230 and the reception coil unit 170 needs a drive circuit. However, the method of driving the power transmission coil unit 230 and the reception coil unit 170 by the drive circuit is a known technique, and the description thereof is omitted here.

  In the above configuration, when the user mounts the electrocardiograph 100 on the mounting table 210 of the trolley 200, the mounting portions provided on the mounting table 210 and the electrocardiograph 100 engage with each other, thereby mounting the electrocardiograph 100. The electrocardiograph 100 is positioned at a predetermined position on the table 210. As a result, the power transmission coil unit 230 and the power reception coil unit 170 are positioned at opposing positions.

  By driving the power transmission coil unit 230 in this state, power is supplied to the power reception coil unit 170 by electromagnetic induction. Incidentally, for example, a sensor for detecting that the electrocardiograph 100 is placed at a predetermined position on the mounting table 210 may be provided, and the drive of the power transmission coil unit 230 may be controlled based on the detection result of this sensor. Specifically, the power transmission coil unit 230 may be driven only when the electrocardiograph 100 is mounted at a predetermined position on the mounting table 210.

  Here, the trolley 200 drives the power transmission coil unit 230 by the power from the power cord 220, for example, when the power cord 220 is plugged into an external AC outlet. On the other hand, the trolley 200 drives the power transmission coil unit 230 by the electric power charged to the battery 240, for example, when the power supply cord 220 is not plugged into an external AC outlet. Of course, if the power transmission coil unit 230 is driven by the electric power charged in the battery 240, the arrangement position of the trolley 200 can be selected without being restricted by the length of the power cord 220.

  As described above, according to the configuration of the present embodiment, by providing the electrocardiograph 100 with the power receiving coil unit 170 that receives power wirelessly by electromagnetic induction, the user can use the electrocardiogram on the mounting surface of the trolley 200. Only by mounting the meter 100, the electrocardiograph 100 can be made to perform AC operation or charging operation, and hence it is possible to realize the electrocardiograph 100 which can eliminate the need for the user to insert and remove the power cord from the AC inlet. . As a result, it is possible to eliminate the trouble of inserting and removing the power cord from the user into the AC inlet, and further, the deterioration due to the friction of the AC inlet and the deterioration due to the rust of the contact are eliminated, leading to improvement of maintainability and grounding in the electrocardiograph The source of the leakage current can be cut off, leading to safety. Furthermore, since the AC inlet can be omitted, the electrocardiograph 100 can be reduced in size and weight.

  Further, since the alignment between the transmitting coil unit 230 and the receiving coil unit 170 can be performed using the existing engaging portions already provided in the electrocardiograph 100 and the trolley 200, the electromagnetic induction can be performed with a small additional configuration. It is possible to realize good power supply by

  Furthermore, compared with the electrocardiograph 100 on which various electrical components are mounted, the trolley 200 has a space margin. Therefore, it is preferable to mount the battery 240 having a larger capacity than the electrocardiograph 100 in the trolley 200. In this way, the frequency of using the power cord 220 can be reduced.

  The above-described embodiment is merely an example of embodying the present invention, and the technical scope of the present invention should not be interpreted in a limited manner by these. That is, the present invention can be implemented in various forms without departing from the scope of the present invention or the main features thereof.

  In the above embodiment, by providing the receiving coil unit 170 on the back side of the circuit board 150, the adverse effect on the electrocardiogram measurement circuit, the electrogram analysis circuit and the image processing circuit due to the noise generated by the electromagnetic induction is reduced. As described above, when the receiving coil unit 170 is provided in the recorder unit 120, the receiving coil unit 170 can be kept away from the electrocardiogram measurement circuit, the electrocardiogram analysis circuit, and the image processing circuit. You can get it.

Although the above embodiment has described the case where the present invention is applied to the electrocardiograph 100, the present invention can also be applied to, for example, a biological information monitor, and a biological information measuring device capable of measuring a plurality of biological information. Can be widely applied. That is, as described above, in the biological information monitor that measures and displays a plurality of biological information such as an electrocardiogram, blood pressure, SpO _{2 and the} like, a plurality of biological information is measured. Since the display unit for displaying information is enlarged, as with multi-induction multi-function electrocardiographs, the battery can be driven by its own battery for a short time, and frequent charging using a power cord or plugging in a power cord It is necessary to perform an uninterrupted AC operation, and therefore, the user is forced to frequently perform the work of plugging the power cord into the AC inlet, resulting in a very troublesome problem.

  In particular, the present invention is suitably applied to a medical biomedical information measurement apparatus which has such a problem and is placed in a trolley.

  The present invention can obtain the effect that the user can eliminate the need to connect and disconnect the power cord to the AC inlet, and is suitable for, for example, a multifunction electrocardiograph.
