Embodiment 1

[0024] FIG. 1 is a schematic diagram showing the overall configuration of a wireless communication type in-subject information acquisition system as a preferred embodiment of the capsule endoscope of the present invention. As an example of this in-subject information acquisition system, a capsule endoscope is used. As shown in FIG. 1 , the wireless communication type in-body information acquisition system includes a capsule endoscope 3 as a capsule medical device and a receiving device 2 as an external device; the capsule endoscope 3 is introduced into the Inside the specimen 1, images of the body cavity are captured by the imaging function, and data such as image signals are sent to the receiving device 2; the receiving device 2 receives the image data of the body cavity transmitted from the capsule endoscope 3 by wireless communication. In addition, the wireless communication-type in-body information acquisition system also includes a display device 4 for monitoring the imag...

Abstract

Surface of a die (53) for inner circumference out of dies forming the front end cover of a capsule type endoscope is irradiated with an ion beam from an ion source (55) of an ion implanting apparatus, and the surface of the die (53) for inner circumference is treated to be roughened slightly and have micro protrusions and recesses in random. Subsequently, the die (53) for inner circumference is combined with other dies and the front end cover is injection molded, thereby enhancing the molding performance of the front end cover without damaging the imaging performance of the capsule type endoscope.

Description

technical field [0001] The present invention relates to an optical window member for a capsule endoscope such as a capsule endoscope, which is introduced into a subject to collect information in the subject. Background technique [0002] In recent years, an ingestible capsule endoscope has been proposed in the field of endoscopes. This capsule endoscope has an imaging function and a wireless communication function. The capsule endoscope has the function of observing (inspecting) in 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 it is naturally discharged. The interior moves with its peristaltic motion, which is photographed in turn. [0003] While moving in the body cavity, the image data captured by the capsule endoscope in the body is sequentially transmitted to the outside through wireless communication and stored in an external memory. By carrying a receiver having a wir...
