Problems solved by technology

Therefore, even if it is desired to further increase internal components in the capsule-shaped housing, or to replace internal components with increased space, the current situation is that there is no storage space in the capsule-shaped housing.
In addition, it is difficult to realize the miniaturization of capsule-type medical devices

Embodiment Construction

[0024] The capsule medical device has an antenna for externally transmitting information obtained from components of the capsule medical device or receiving information provided from the outside. The inventors of the present application focused on the following situation: the conventional antenna accommodated in the capsule medical device forms the antenna described in Japanese Patent Laid-Open No. 2005-329247. figure 1 In the three-dimensional shape shown, there is a no-signal zone inside the antenna. In addition, the inventors of the present application found a case where more space can be provided by reducing or eliminating the above-mentioned no-signal area.

[0025] The present invention is an antenna to be built in a capsule medical device. The antenna includes: an antenna conductor; and a plate-shaped antenna substrate electrically contacting at least a part of the antenna conductor. The antenna substrate is attached tightly. As in the present invention, the antenna i...

Abstract

An antenna to be embedded in a capsule type medical device (21). The antenna includes an antenna conductor (29a;29b;29;52a;52b;52), and a sheet-like antenna substrate (28a) which at least partly electrically contacts with the antenna conductor (29a;29b;29;52a;52b;52). The antenna is formed by closely attaching the antenna conductor (29a;29b;29;52a;52b;52) and the sheet-like antenna substrate (28a).

Description

technical field [0001] The present invention relates to an antenna for a capsule medical device as an antenna used for a capsule medical device, and a capsule medical device using the antenna for a capsule medical device. Background technique [0002] In recent years, capsule-type medical devices that are inserted into the body of a subject for in-vivo observation, inspection, treatment, or treatment have come into practical use. The capsule medical device has a capsule-shaped housing, and various internal components housed in the capsule-shaped housing, such as an imaging unit, a transmitter, an antenna, and a power source. A capsule endoscope is known as such a capsule-type medical device. As a capsule endoscope, there is, for example, a swallowable capsule described in JP-A-2005-329247. [0003] However, in the above-mentioned capsule medical device, an aggregate is formed in which internal components are arranged relatively close to each other. In addition, the aggrega...
