Embodiment approach 1

[0032] FIG. 1 is a schematic diagram showing the overall configuration of a wireless in-vivo information acquisition system according to the first embodiment. As shown in FIG. 1 , the wireless in-vivo information acquisition system includes: a capsule endoscope 2, which is introduced into the body of a subject 1, and captures images in the body cavity; Mirror 2's wireless transceiver function. Furthermore, the wireless in-vivo information acquisition system includes: a display device 4 for displaying an in-vivo image based on data received by the transmitter-receiver device 3; The transmitting and receiving device 3 includes: a transmitting and receiving jacket 3b worn by the subject 1; and an external device 3a for processing wireless signals transmitted and received by the transmitting and receiving jacket 3b. The receiving antenna A1 and the amplifier C1 are disposed on the transmitting and receiving jacket 3b.

[0033] The display device 4 is used to display the in-body c...

Embodiment approach 2

[0053] Next, a wireless in-vivo information acquisition system according to Embodiment 2 will be described. The wireless in-vivo information acquisition system of Embodiment 2 further includes an antenna for power recovery, which is disposed on the transmission and reception jacket, recovers a part of the wireless signal transmitted from the transmission and reception device, and has an amplifying unit that uses the power obtained by the antenna for power recovery. The structure of the driving power. In addition, in the second embodiment, the capsule endoscope 2 , the display device 4 , and the portable recording medium 5 have the same configurations as those in the first embodiment.

[0054]FIG. 7 is a block diagram showing the configuration of the transmission and reception jacket 41 constituting the transmission and reception device according to the second embodiment. The transmitting and receiving jacket 41 has the same receiving antennas A1 to An, power feeding antennas ...

Abstract

There are included a capsule-like endoscope (2) for capturing intracoelomic images; and a transmitter / receiver apparatus (3) having a wireless transmission / reception function for the capsule-like endoscope (2). There are further included a display device (4) for displaying, based on data received by the transmitter / receiver apparatus (3), intracoelomic images; and a mobile recording medium (5) for delivering data between the transmitter / receiver apparatus (3) and the display device (4). A transmitter / receiver jacket (3b) constituting the transmitter / receiver apparatus (3) includes a reception antenna (A1) for receiving radio signals transmitted from the capsule-like endoscope (2); and an amplifier (C1) provided in the vicinity of the reception antenna (A1). The provision of the amplifier (C1) in the vicinity of the reception antenna (A1) can suppress the attenuation of received radio signals and also suppress the admixture of noise signals.

Description

technical field [0001] The present invention relates to a wireless in-body information acquisition system, which includes: an in-body introduction device that is introduced into a subject to acquire information on the subject; A receiving device for in-body information wirelessly transmitted by the device introduced into the subject. Background technique [0002] In recent years, in the field of endoscopes, swallow-type capsule endoscopes have appeared. This capsule endoscope is provided with an imaging function and a wireless communication function. Capsule-type endoscopes have the function of moving with peristaltic movements in internal organs such as the stomach and small intestine in body cavities such as the stomach and small intestine during the period from swallowing the subject's mouth for observation (examination) to natural excretion. Take pictures sequentially. [0003] While moving in the body cavity, the image data captured by the capsule endoscope in the bo...
