Problems solved by technology

[0009] However, in conventional receivers, the received high-frequency signal is demodulated into a baseband signal integratedly, predetermined signal processing is performed on the demodulated baseband signal, image data is obtained, and the image data is stored in a memory. Therefore, when changing the number of antennas according to the inspection application, or changing the radio frequency according to the area of ​​use, there is a problem that the entire receiving device needs to be changed, and it takes labor every time such a specification change is made. and time, no flexibility
In this case, it is difficult to normally receive wireless signals from the capsule endoscope introduced into the subject
[0012] However, in the above-mentioned conventional antenna unit, there is no structure capable of recording the number of times of use of the receiving antenna electrically connected via the cable, so it is difficult to confirm whether the received receiving antenna exceeds the usage limit.
Therefore, when performing a task of receiving wireless signals from the capsule endoscope in the subject, for example, a receiving antenna that cannot normally receive wireless signals due to a cable breakage may occur.

Embodiment approach 1

[0056] figure 1 It is a schematic diagram showing the overall configuration of a wireless in-vivo information acquisition system using the receiving device 2 of the present invention. Such as figure 1 As shown, the wireless in-body information acquisition system includes: a plurality of antennas A1-An having a wireless receiving function; a receiving device 2 connected to the plurality of antennas A1-An; and a capsule endoscope 3, which is introduced into The body cavity of the subject 1 is photographed, and the image data and the like are transmitted to the receiving device 2 through a high-frequency signal (wireless signal). Such a capsule endoscope 3 is introduced into the subject 1, has an imaging function for capturing images inside the subject 1, and transmits image data to a receiving device outside the subject 1 through predetermined radio waves. function of the device. In addition, the wireless in-body information acquisition system has a display device 4 for displ...

Embodiment approach 2

[0074] Next, Embodiment 2 of the present invention will be described. In Embodiment 1, the demodulation control unit 20 is arranged in the antenna unit 2a, and the antenna unit 2a performs demodulation control. However, in the present Embodiment 2, a binarization unit for converting a digital baseband signal is provided. For this The control unit of the binarization unit is also provided on the side of the antenna unit 20a.

[0075] Figure 4 It is a block diagram showing a schematic configuration of a receiving device 2A according to the second embodiment. Such as Figure 4 As shown, the receiving device 2A has an antenna unit 20a instead of the antenna unit 2a of the receiving device 2 according to Embodiment 1, and has a receiving device main body 20b instead of the receiving device main body 2b. Such an antenna unit 20a and the receiving device main body 20b are detachably connected by the connector 20c as in the case of the above-mentioned connector 2c. The antenna un...

Embodiment approach 3

[0082]Next, Embodiment 3 of the present invention will be described. In the first and second embodiments described above, the antenna units 2a and 20a demodulate high-frequency signals into baseband signals S2 and SE, but in the third embodiment, antenna switching control is also performed on the antenna unit side.

[0083] Figure 6 It is a block diagram showing a schematic configuration of a receiving device 2B according to the third embodiment. Such as Figure 6 As shown, the receiving device 2B has an antenna unit 21a instead of the antenna unit 20a of the receiving device 2A according to Embodiment 2, and has a receiving device main body 21b instead of the receiving device main body 20b. Such an antenna unit 21a and the receiving device main body 21b are detachably connected by the connector 21c as in the case of the above-mentioned connector 20c. On the side of the antenna unit 21a, there is also provided a switching control unit 40 for performing switching control of...

Abstract

The present invention provides an antenna unit and a receiving device using the antenna unit. An object of the present invention is to provide a receiving apparatus that can cope with various specifications with a simple structure. The receiving apparatus of the present invention includes an antenna unit and a receiving apparatus main body that is detachable from the antenna unit, and the antenna unit is provided with a receiving apparatus for receiving a wireless signal including image information transmitted by a capsule endoscope introduced into the subject. antenna. The antenna unit functions to demodulate the wireless signal received via the receiving antenna into a baseband signal, and the main body of the receiving apparatus obtains the image information from at least the baseband signal.

Description

technical field [0001] The present invention relates to an antenna unit provided with a receiving antenna for receiving wireless signals including image data captured by a capsule endoscope introduced into a subject, and a receiving device using the antenna unit. Background technique [0002] In recent years, in the field of endoscopes, capsule-type endoscopes, which are ingestion-type endoscopes equipped with an imaging function and a wireless communication function, have appeared, and are being developed as a method for obtaining objects captured by the capsule-type endoscope. A wireless in-vivo information acquisition system of a capsule endoscope system for image data in a test object. In this wireless in-vivo information acquisition system, the capsule endoscope performs the function of swallowing the capsule endoscope from the subject's mouth for observation (examination) until it is naturally discharged from the subject. During this period, the capsule endoscope move...
