Embodiment 1

[0042] First, the system introduced into the subject of Example 1 will be described. figure 1 It is a schematic diagram showing the overall configuration of the subject introduction system of Example 1. Such as figure 1 As shown, the system for introducing into the subject according to the first embodiment includes: the capsule endoscope 2 introduced into the subject 1; processing, etc.; the display device 4, which displays the contents of the wireless signal received by the receiving device 3 and transmitted from the capsule endoscope 2; and the portable recording medium 5, which is transmitted between the receiving device 3 and the display device 4 information exchange. In addition, if figure 1 As shown, in this embodiment 1, the object coordinate axis and the reference coordinate axis are set. The object coordinate axis is formed by the X axis, the Y axis and the Z axis, and is a fixed coordinate axis relative to the capsule endoscope 2. The reference coordinate The axe...

Embodiment 2

[0100] Next, the subject body introduction system of Example 2 will be described. Like Embodiment 1, this Embodiment 2 adopts the following structure: the receiving unit and the position detection unit formed independently of each other constitute the receiving device, and the capsule endoscope 2 starts the magnetic field according to the formation of the magnetic field for position detection by the position detection unit. detection.

[0101] Figure 12 It is a schematic block diagram showing the configuration of the capsule endoscope 63 constituting the intra-subject introduction system of the second embodiment. Furthermore, despite the Figure 12 The illustrations are omitted below, but similarly to the first embodiment, the intra-subject introduction system of the second embodiment includes a display device 4 and a portable recording medium 5 . Also, yes Figure 12 The constituent elements shown below have the same structures / functions as those in Embodiment 1, unless ...

Embodiment 3

[0113]Next, the subject body introduction system of Example 3 will be described. The body-introduction system of the third embodiment has a configuration in which position detection is performed by using geomagnetism instead of the first linear magnetic field in the position detection means. In addition, in the following description, the structure example based on Example 1 is demonstrated, However, Of ​​course, the structure which uses earth magnetism instead of a 1st linear magnetic field can also be employ|adopted about the structure of Example 2.

[0114] Figure 16 It is a schematic diagram showing the overall configuration of the subject introduction system of Example 3. Such as Figure 16 As shown, the subject introduction system of the third embodiment has the capsule endoscope 2, the display device 4, and the portable recording medium 5 similarly to the first embodiment, and the difference is that the position detection unit 71 of the receiving device 70 is formed. ...

Abstract

The invention provides a system for introducing into a subject, a receiving device and a device for introducing into a subject. The receiving device (3), which is a structural element of the system introduced into the subject, has a structure in which a receiving unit (6) and a position detecting unit (7) are formed independently, wherein the receiving unit (6) consists of receiving antennas (8a-8d) Consists of a reception processing device (9), a position detection unit (7) consisting of a transmitting antenna (10a-10d), a first linear magnetic field forming part (11a), a second linear magnetic field forming part (11b), a diffusion magnetic field forming part (12 ) and processing device (13) constitute. Therefore, when the subject body introduction system is used for the purpose of acquiring in-subject information acquired by the capsule endoscope (2) and position detection of the capsule endoscope (2), the receiving unit (6 ) and the position detection unit (7), in the case of only obtaining the information in the subject, only the receiving unit (6) can be used, thereby suppressing the increase of the use cost, and the subject bears the burden during use. The degree of burden is limited to the minimum corresponding to the purpose of use.

Description

technical field [0001] The present invention relates to a device introduced into a subject, which acquires in-vivo information as information related to the subject, and transmits a wireless signal including the acquired in-subject information, and is performed by the A receiving device for receiving and processing wireless signals transmitted from the device introduced into the subject, and a system introduced into the subject composed of the device introduced into the subject and the receiving device. Background technique [0002] In recent years, swallowing capsule endoscopes have been proposed in the field of endoscopes. This capsule endoscope is provided with an imaging function and a wireless communication function. Capsule-type endoscopes have the function of observing (inspecting) inside internal organs such as the stomach and small intestine in the body cavity after being swallowed from the mouth of the subject (human body) until being naturally discharged. It mov...
