  Endoscopes are used in applications such as in vivo observation in the medical field. In recent years, there has been proposed a capsule endoscope that is a biological information acquisition device that is introduced into the body by swallowing a subject and that captures an image while moving in the body with a peristaltic motion. While moving inside the body cavity, image data imaged inside the body by the capsule endoscope is sequentially transmitted to the outside as image communication and stored in a memory provided in an external receiver. The subject can move freely after swallowing the capsule endoscope by carrying the receiver.

  The capsule endoscope obtains driving power from a battery or the like built in the housing. Since the internal circuit and the like are sealed in the housing, the operator cannot start / stop by operating a switch or the like disposed on the outer surface of the housing.

  However, when the capsule endoscope is transported, the capsule endoscope may be erroneously activated due to unexpected disturbance noise, for example, a signal to an RFID tag used for material management. If the capsule endoscope is activated during transportation, the built-in battery is consumed before use. As a result, the capsule endoscope cannot be used, or a sufficient operating time cannot be secured, and the site to be observed cannot be observed.

<First Embodiment>
Hereinafter, the storage container 1 with a capsule endoscope, which is a storage container with a biological information acquisition device according to the first embodiment of the present invention, will be described with reference to FIGS.

  As shown in FIG. 1, a storage container 1 with a capsule endoscope of the present embodiment includes a capsule endoscope 10 that is a biological information acquisition device that can be introduced into a digestive organ lumen in a subject, and a capsule And a storage unit 20 for storing the mold endoscope 10. The storage unit 20 includes a storage case 20 </ b> A and a transmission / reception unit 40. The transmission / reception unit 40 includes a transmission coil 27 wound around the storage case 20A, a switch 22, and the like. The functions of the transmission coil 27, the switch 22, and the transmission / reception unit 40 will be described in detail later.

  The storage case 20A is a so-called blister pack, which is a storage case main body 20B for storing the capsule endoscope 10 and a seal that seals the storage case main body 20B and can be peeled off from the storage case main body 20B. 20C. Although FIG. 1 shows a state in which a part of the lid 20C is peeled off from the storage case main body 20B, the lid 20C can be peeled off and separated from the storage case main body 20B.

  After manufacturing, the capsule endoscope 10 is stored in the storage case body 20B and sealed by the lid 20C, and is kept in a clean state because it is distributed and stored as a storage container with a capsule endoscope. . Then, the operator peels off the lid 20C of the storage case 20A and takes out the capsule endoscope 10 for use.

  First, the capsule endoscope 10 will be described with reference to FIGS. As illustrated in FIG. 2, the capsule endoscope 10 includes an illumination unit 11, an imaging unit 12 that is an information acquisition unit, and an image signal transmission unit that is an information signal transmission unit, which are sealed inside a housing 16. 13, a power supply control unit (hereinafter also referred to as “control unit”) 14, a magnetic field signal receiving unit 15 that is an activation control signal receiving unit, a battery 14 </ b> A that supplies driving power to the imaging unit 12 and the image signal transmitting unit 13. (See FIG. 3). The casing 16 has an elongated capsule shape, the end portion 16A on the imaging unit 12 side has a dome shape made of a transparent material, and the central cylindrical portion 16B and the opposite dome-shaped end portion 16C have a light shielding material. It is configured. Note that a capsule endoscope having an image sensor at both ends and having both ends made of a transparent material may be used.

  Next, the circuit configuration of the capsule endoscope 10 will be described with reference to FIG. As shown in FIG. 3, a main function unit 17 is configured by an image acquisition unit 17 </ b> A, an image signal transmission unit 13, and an antenna 13 </ b> A that are information acquisition units including an illumination unit 11 and an imaging unit 12.

  The main function unit 17 acquires an image in the body of the subject and transmits it as an image signal. The battery 14 </ b> A is a power supply unit that supplies power used to drive the main function unit 17. The magnetic field signal receiving unit 15 receives an activation control signal generated by the alternating magnetic field (electromagnetic field) generated by the storage unit 20, rectifies it, and outputs it as a direct current. The power supply control unit (hereinafter also referred to as “control unit”) 14 includes a divide-by-2 circuit 14C and a switch 14B, and from the battery 14A to the main function unit 17 based on an electrical signal from the magnetic field signal reception unit 15. ON / OFF control of the power supply.

  The illuminating unit 11 of the capsule endoscope 10 includes an LED (not shown) for irradiating an imaging region when photographing the inside of the subject, and an LED driving circuit (not shown) for controlling the driving state of the LED. . The imaging unit 12 includes a CCD (not shown) that images an area irradiated by the LED, and a signal processing circuit (not shown) that processes an image signal output from the CCD into image data of a desired format. The image signal transmission unit 13 includes an image signal transmission unit (not shown) that generates image signals by modulating image data captured and processed by the CCD, and the antenna 13A is an image signal output from the image signal transmission unit. Send. In addition, although LED was illustrated as an illumination means, if it can irradiate an imaging region, it will not limit to this. Further, although the CCD is exemplified as the image pickup means, the present invention is not limited to this as long as it is possible to pick up an image. For example, a CMOS sensor or the like may be used.

  The magnetic field signal receiving unit 15 includes an antenna 35, a diode 38 constituting a rectifier circuit, a smoothing capacitor 37, and a resistor 34. The antenna 35 is a resonance circuit having a secondary coil 36A and a secondary capacitor 36B, and is adjusted so as to resonate with the frequency of the activation control signal. The secondary side coil 36 </ b> A is, for example, a coil or a planar coil wound in the circumferential direction of the casing 16, and efficiently receives an electromagnetic field parallel to the longitudinal direction of the elongated casing 16.

  An activation control signal generated by an AC magnetic field from the outside generates an AC current in the secondary coil 36A by electromagnetic induction. The alternating current generated by the start control signal received by the antenna 35 is rectified by the diode 38, smoothed by the smoothing capacitor 37, and transmitted to the divide-by-2 circuit 14C of the control unit 14 as a direct current electric signal at the received voltage level. Is done. That is, since the capsule endoscope 10 magneto-electrically converts the received activation control signal to obtain a direct current, a power source for the magnetic field signal receiving unit 15 to detect the magnetic field is unnecessary.

  The divide-by-2 circuit 14C has a D-type flip-flop circuit, and outputs a signal obtained by dividing the input electric signal by two to the switch 14B. The switch 14B includes a P-channel FET having a source connected to the battery 14A, a gate connected to the output of the divide-by-2 circuit 14C, and a drain connected to each circuit of the main function unit 17.

  When the magnetic field signal receiving unit 15 detects an AC magnetic field (receives power), the output electric signal (node N1) becomes a high level of the received voltage level. When the received voltage level exceeds the threshold of the divide-by-2 circuit 14C, the output of the divide-by-2 circuit 14C (node N2) becomes the ground voltage level, the switch 14B is turned on, and the main function unit 17 of the capsule endoscope 10 is turned on. Starts operation.

  When the output signal of the divide-by-2 circuit 14C is at the power supply voltage level, the switch 14B is off and power to the main function unit 17 is not supplied. Conversely, when the output signal of the divide-by-2 circuit 14C is at the ground voltage level, the switch 14B is turned on and power is supplied to the main function unit 17.

  As described above, the switch 14B performs a toggle operation in which the ON / OFF state is switched by one operation of the magnetic field signal receiving unit 15. That is, the switch 14B changes from the off state to the on state, or from the on state to the off state by one operation in which the magnetic field signal receiving unit 15 detects the magnetic field once. That is, the divide-by-2 circuit 14C functions as a state holding unit for the switch 14B. The D-type flip-flop circuit of the divide-by-2 circuit 14C may be another circuit as long as it can divide the input signal by two, and may be a T-type flip-flop circuit or the like.

  Next, the circuit configuration of the transmission / reception unit 40 of the storage unit 20 will be described with reference to FIG. The transmission / reception unit 40 includes an image signal reception unit 41 that is a start detection unit, a magnetic field signal transmission unit 21 that is a stop signal transmission unit, and a power source 47 such as a battery. The image signal receiving unit 41 is an information signal receiving unit that receives an image signal to be transmitted when the capsule endoscope 10 is activated. That is, the image signal receiving unit 41 of the storage unit 20 of the storage container 1 with a capsule endoscope is an activation detection unit that detects the start of supply of driving power to the capsule endoscope 10 by receiving an image signal.

  The activation detection unit may detect light generated by the illumination unit 11 of the activated capsule endoscope 10 with a photodiode or the like, or may detect activation by another method.

  As shown in FIG. 4, the image signal receiving unit 41 includes a receiving antenna 45, a receiving unit 44, a timer unit 43, a comparator 42, and a switch 46. The circuit of the reception antenna 45 is a resonance circuit that resonates with the frequency of the image signal of the capsule endoscope 10 and can efficiently receive the image signal.

  An image signal transmitted from the capsule endoscope 10 and received by the receiving antenna 45 is input to the input terminal (B1) of the comparator 42 via the receiving unit 44 and further to the other side of the comparator 42 via the timer unit 43. Input terminal (B2). The output signal of the comparator 42 controls the switch 46 to be turned on or off. The set time of the timer unit 43 is arbitrary, but is, for example, 1 minute.

  The magnetic field signal transmission unit 21 includes a transmission coil 27, a resonance capacitor 26, a switch 22, an oscillator 23, a frequency adjustment unit 24, and a driver 25. The switch 22 is a switch operated by the operator, for example, a push button switch. The frequency adjusting unit 24 performs processing such as setting a signal from the oscillator 23 to a desired frequency, and transmits a signal having a predetermined frequency to the driver 25. The driver 25 drives the transmission coil 27 by the input signal, and the transmission coil 27 generates an alternating magnetic field having a predetermined frequency according to the signal. The AC magnetic field generated by the magnetic field signal transmission unit 21 not only functions as a stop signal for stopping the capsule endoscope 10, but also functions as a start control signal for controlling start or stop.

  Note that the frequency of the alternating magnetic field generated by the storage unit 20 as the activation control signal is preferably a frequency that is standardized as a frequency used by the RFID tag. Not only the legal problem of electromagnetic wave emission, but also the magnetic field signal transmission unit 21 of the storage unit 20 and the magnetic field signal reception unit 15 of the capsule endoscope 10 are configured by general-purpose electronic components that are inexpensive and highly reliable. Because it can.

  The frequency of the alternating magnetic field is particularly preferably 13.56 MHz, which is internationally standardized as the frequency for the RFID tag in ISO 10536/14443/15693 of the International Organization for Standardization. As described above, since the capsule endoscope 10 can be used as energy by magneto-electrically converting the electromagnetic wave of the activation control signal, the power of the built-in battery 14A is consumed when the main function unit 17 is stopped. There is nothing to do. For this reason, even if days pass after manufacture, it is because the in-vivo observation possible time is securable.

  However, RFID tags are used in many applications including logistics management. For this reason, the capsule endoscope 10 that uses the electromagnetic field of the frequency used by the RFID tag as the activation control signal may receive a magnetic field signal of the same frequency in the distribution stage or the like, that is, erroneously activated. There is a possibility that.

  However, as will be described later, when the capsule endoscope 10 is accidentally activated during transportation / storage, the storage unit 20 automatically transmits a stop signal and receives the stop signal. The capsule endoscope 10 stops.

  For this reason, the capsule-equipped endoscope-containing storage container 1 according to the present embodiment can prevent consumption of the capsule endoscope 10 before use of the battery 14A.

  Further, as already described, the stop signal transmitted by the magnetic field signal transmission unit 21 of the storage unit 20 is a start control signal for stopping or starting the supply of the driving power of the capsule endoscope 10. For this reason, in use, the operator can start and stop the capsule endoscope 10 by operating the switch 22 of the storage unit 20.

Next, the flow of the operation of the capsule-equipped endoscope-containing storage container 1 will be described using the flowchart of FIG.
<Step S10>
After the capsule endoscope 10 is stored in the storage case main body 20B of the storage unit 20, the storage case main body 20B is sealed by the lid 20C, and the storage container 1 with the capsule endoscope is manufactured.

<Step S11>
The capsule endoscope 10 stored in the storage container 1 with the capsule endoscope is in a stopped state, that is, in a state where the supply of driving power is stopped until the magnetic field signal which is the activation control signal is received (Yes). Maintain (No). For this reason, the power of the built-in battery 14A is not consumed. And if a starting control signal is received (Yes), the process after step S12 will start.

  Even if the activation control signal is intentionally transmitted to activate the capsule endoscope 10, it is transmitted to an RFID tag or the like such as another article in the distribution / storage stage. Even so, the following operations are almost the same.

<Step S12>
When the magnetic field signal receiving unit 15 of the capsule endoscope 10 receives a magnetic field signal that is an activation control signal (step S11: Yes), the control unit 14 performs ON control (start) of power supply to the main function unit 17. To do.

<Step S13>
When the control unit 14 of the capsule endoscope 10 controls the supply of power to the main function unit 17, the main function unit 17 is activated and starts operating. That is, the image signal transmission unit 13 starts transmitting an image signal.

<Step S14>
The storage unit 20 is in a standby state until the reception unit 44 of the image signal reception unit 41 of the transmission / reception unit 40 receives an image signal via the reception antenna 45 (No).
When receiving the image signal (Yes), the receiving unit 44 outputs the image signal that is the activation detection signal “H”.

<Step S15>
The timer unit 43 of the image signal receiving unit 41 of the storage unit 20 starts counting, that is, time measurement.

<Step S16>
The timer unit 43 outputs a signal “L” when the count time is a set time (for example, 1 minute) or less, and outputs a signal “H” when the count time is exceeded. The comparator 42 compares the image signal “H” from the receiving unit 44 with the signal from the timer unit 43, and if the same “H” (step S 15: Yes), the switch 46 is turned on.

<Step S17>
When the switch 46 is turned on, the magnetic field signal transmission unit 21 of the storage unit 20 transmits a magnetic field signal that is a stop signal (startup control signal), similarly to when the switch 22 is pressed.

<Step S18>
The activated capsule endoscope 10 continues to operate the main function unit 17 until the activation control signal is received again (No).

<Step S19>
When the activation control signal is received from the storage unit 20 (step S18: Yes), the power supply control unit 14 of the activated capsule endoscope 10 controls the power supply to the main function unit 17 to OFF (stop). ) That is, the capsule endoscope 10 stops.

  The operation of the timer unit 43 of the storage unit 20 is based on whether the capsule endoscope 10 is activated due to a magnetic field signal transmitted to activate the operator, or an erroneous magnetic field during transportation / storage. This is for distinguishing between signals. That is, when the operator operates the switch 22 to activate the capsule endoscope 10, the capsule endoscope 10 is removed from the storage case 20A after a predetermined time. For this reason, even if the storage unit 20 transmits a magnetic field signal in step S17, the capsule endoscope 10 does not receive the magnetic field signal, and thus maintains the activated state. On the other hand, when activated by an incorrect magnetic field signal, the capsule endoscope 10 remains in the storage case 20A, that is, inside the solenoid of the transmission coil 27 even after a predetermined time. For this reason, the capsule endoscope 10 receives the magnetic field signal and stops.

  In addition, after the capsule endoscope 10 is taken out from the storage case 20A, the storage unit 20 may not transmit the magnetic field signal. For example, an opening detection sensor may be provided on the lid 20C and control may be performed based on the output of the opening detection sensor, or a part of the output wiring from the power supply 47 of the transmission / reception unit 40 may be provided on the lid 20C. In addition, the output wiring may be disconnected by peeling off the lid 20C.

  Alternatively, even when the image signal is received and the timer unit 43 starts counting for a predetermined time, when the capsule endoscope 10 is taken out from the storage case 20A and the image signal cannot be received, the storage unit 20 operates. You may make it cancel.

  Note that a DC magnetic field can also be used as the activation control signal, and the configuration of the magnetic field signal receiving unit 15 of the capsule endoscope 10 and the magnetic field signal transmitting unit 21 of the storage unit 20 can be simplified. For example, the magnetic field signal receiving unit 15 can use a reed switch.

<Second Embodiment>
Next, a storage container 101 with a capsule endoscope, which is a storage container with a biological information acquisition device according to a second embodiment of the present invention, will be described with reference to FIGS. Since the storage container 101 with a capsule endoscope according to the present embodiment is similar to the storage container 1 with a capsule endoscope according to the first embodiment, components having the same functions are denoted by the same reference numerals. Description is omitted.

  As shown in FIG. 6, a storage container 101 with a capsule endoscope according to the present embodiment includes a capsule endoscope 110 that is a biological information acquisition device to be introduced into a subject, and a capsule endoscope 110. And a storage unit 120 stored therein. The storage unit 120 includes a storage case 120A and an RF tag 120D described later.

  In other words, the storage case 120A of the storage unit 120 is a seal that seals the storage case main body 120B for storing the capsule endoscope 110 and the storage case main body 120B, and can be peeled off from the storage case main body 120B. 120C, and the RF tag 120D is disposed on the lid 120C.

  As shown in FIG. 7, the capsule endoscope 110 according to the present embodiment includes a magnetic field signal receiving unit 15 and a main function unit 17 included in the capsule endoscope 10 according to the first embodiment. In addition to the battery 14A, the power supply control unit 114 includes not only the magnetic field signal receiving unit 15 but also the main signal from the battery 14A based on a signal from the stop signal receiving unit 18. The power supply to the function unit 17 is turned off (stopped).

  On the other hand, as illustrated in FIG. 8, the RF tag 120 </ b> D of the storage unit 120 includes an image signal reception unit 141 and a stop signal transmission unit 121. The function of the image signal receiving unit 141 of the present embodiment is almost the same as that of the image signal receiving unit 41 of the first embodiment. However, since the image signal receiving unit 141 rectifies the received electromagnetic wave and obtains a direct current in the same manner as the magnetic field signal receiving unit 15 of the capsule endoscope 10 of the first embodiment, the RF tag 120D has a power supply. Is unnecessary.

  In addition, the stop signal transmitting unit 121 transmits a stop signal received by the stop signal receiving unit 18 of the capsule endoscope 110. The stop signal may be a signal different from the image signal and the start control signal.

Next, the flow of operation of the capsule-type endoscope-containing storage container 101 will be described using the flowchart of FIG.
<Step S20 to Step S23>
The operation is the same as that of Step S10 to Step S13 of the capsule-type endoscope-containing storage container 1 of the first embodiment.

<Step S24>
The image signal receiving unit 141 of the storage unit 120 receives the image signal, rectifies the received image signal to obtain a DC power source, and transmits the activation detection signal to the stop signal transmission unit 121 (Yes). That is, the image signal receiving unit 141 is in a standby state until an image signal is received (No).

<Step S25>
When the stop signal transmission unit 121 of the storage unit 120 receives the activation detection signal from the image signal reception unit 141, the stop signal transmission unit 121 transmits a stop signal. That is, since the image signal receiving unit 141 and the stop signal transmitting unit 121 that are activation detection units operate using the electromagnetic wave of the image signal that is the information signal received by the image signal receiving unit 141 as a power source, the storage unit 120 is powered. It is unnecessary.

<Step S26>
When receiving the stop signal (Yes), the stop signal receiver 18 of the capsule endoscope 110 sends a signal to the controller 114.

<Step S27>
When receiving the signal from the stop signal receiving unit 18, the control unit 114 of the capsule endoscope 110 performs OFF control (stops) the power supply to the main function unit 17. That is, the capsule endoscope 110 stops.

  As described above, when the capsule endoscope 110 is activated by an erroneous magnetic field signal during transportation or storage, the capsule endoscope 110 is removed from the storage unit 120. In order to receive the stop signal, the supply of drive power is automatically stopped.

  On the other hand, when the capsule endoscope 110 is activated by the magnetic field signal transmitted for activation by the operator, the stop signal receiving unit 18 of the capsule endoscope 110 receives the stop signal in step S26. Therefore, the capsule endoscope 110 maintains the activated state. That is, when the operator intentionally starts up the capsule endoscope 110, the start-up control signal is applied after the capsule endoscope 110 is taken out of the storage section 120. It is outside the reach of the image signal transmitted by the endoscope 110. For this reason, since the image signal receiving unit 141 of the storage unit 120 does not receive the image signal, the stop signal transmitting unit 121 does not transmit the stop signal.

  Alternatively, in the storage container 101 with the capsule endoscope, the operator may start up in a state of being stored in the storage case main body 120A in order to maintain the clean state of the capsule endoscope 110. In this case, the operator applies the activation control signal after peeling off and separating the lid 120C from the storage case main body 120A. Then, when the capsule endoscope 110 is activated, the RF tag 120D together with the lid portion 120C is located away from the capsule endoscope 110. For this reason, since the image signal receiving unit 141 of the RF tag 120D does not receive the image signal, the stop signal transmitting unit 121 does not transmit the stop signal.

  Further, like the container 1 with a capsule endoscope according to the first embodiment, the stop signal receiving unit 18 and the like have a timer unit, and the stop signal is transmitted while the timer unit is counting a predetermined time. The unit 121 may be controlled not to transmit a stop signal. In this case, the operator activates the capsule endoscope 110 that is sealed by the lid portion 120C, peels the lid portion 120C from the storage case main body portion 120A within a predetermined time, and the capsule endoscope 110. Can be taken out.

  As described above, since the capsule-equipped endoscope storage container 101 according to the present embodiment immediately stops even if the capsule endoscope 110 is erroneously activated, it prevents the battery 14A from being consumed before use. it can. Further, in the capsule-type endoscope-containing storage container 101, the image signal receiving unit 141 and the stop signal transmitting unit 121 are disposed on the lid 120C that can be peeled off from the storage case body 120A as the RF tag 120D. The capsule endoscope 110 can also be activated while maintaining a clean state. Furthermore, since the RF tag 120D operates using the received image signal, which is an electromagnetic wave, as a power source, no power source is required.

  In the above description, the capsule endoscope has been described as an example of the biological information acquisition device. However, as a capsule medical device for collecting digestive fluid, a swallowable capsule temperature sensor, or a swallowable capsule pH sensor, The present invention can be applied to various capsule-type biological information acquisition devices. Moreover, the storage part of the storage container with the biometric information acquisition device can be recycled.

  The present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the scope of the present invention.
