Problems solved by technology

In addition, in the capsule endoscope disclosed in Japanese Patent Laid-Open No. 2001-91860, in the bonding process of bonding the transparent cover and the cylindrical cover with an adhesive, it is difficult to manage so that the adhesive The amount of coating is a certain amount of problems
In addition, during bonding, unevenness or valleys are formed on the outer surface of the capsule by excess adhesive. In this case, complicated post-processing is required to make the outer surface of the capsule smooth.

Embodiment 1

[0035] Fig. 1 is a side sectional view showing the structure of the first embodiment of the capsule medical device of the present invention, and Fig. 2 is a plan view after unfolding the rigid flexible wiring board shown in Fig. 1. In addition, in this embodiment, as an example, a capsule endoscope that is introduced into a body cavity from the mouth or the like of a person as a subject, and photographs an inspection site in the body cavity is described.

[0036] The capsule endoscope 1 as shown in FIG. 1 includes: a closed container 2 as an outer casing formed in a capsule shape; an illumination unit 3 as a function execution unit for executing a predetermined function set in advance. The body cavity emits illuminating light for illuminating the inspected part; the imaging unit 4, as a function execution unit, receives the reflected light of the illuminating light and photographs the inspected part; executes the drive control and signal processing of the illumination unit 3 and t...

Embodiment 3

[0094] Figure 13 It is a figure explaining the example of the ultrasonic welding operation of Example 3 of this invention. As shown in the figure, in this embodiment, the ultrasonic welding machine 150 is arranged in the vacuum furnace 160, and the ultrasonic welding operation is performed in a vacuum environment.

[0095] That is, in this embodiment, as described Picture 12 As shown, the observation side cover 111 is arranged in a predetermined state for the capsule body 112 on which the tubular member 123 and the like are assembled on the mold 151 of the ultrasonic welding machine 150, and the welding head 152 is arranged in contact with the observation side cover. When the installation of the step portion 125 on the 111 is completed, vacuum extraction is performed, and then the welding operation is performed.

[0096] Thereby, no air remains in the capsule internal space formed by the observation side cover 111 and the capsule main body 112. Therefore, during the period from...

Abstract

PROBLEM TO BE SOLVED: To enhance safety by assuring a liquid-tightness of a container and also to improve light transmittance of the container.SOLUTION: An outer surface 21a of a front cover 21, a joint surface 24a of a joint end section 24 of the front cover 21, and a joint surface 25a of a joint end section 25 of a body cover are subjected to plasma treatment by atmospheric pressure plasma treatment to form a plurality of microscopic irregularities on the outer surface 21a and the joint surfaces 24a and 25a. The joint surfaces 24a and 25a are engaged and attached by an adhesive after the hydrophilicity of the outer surface 21a and the joint surfaces 24a and 25a is enhanced.

Description

Technical field [0001] The present invention relates to a capsule medical device such as a swallowable capsule endoscope that is introduced into a subject to collect information in the subject, and more particularly to a capsule medical device that maintains high liquid tightness, and a structure A medical capsule housing of an exterior part of a medical capsule for performing observation, inspection, or treatment in a subject, and a manufacturing method thereof. Background technique [0002] In recent years, in the field of endoscopes, capsule endoscopes equipped with imaging functions and wireless functions have appeared. The structure of the capsule endoscope is such that after being swallowed by the examinee as the subject for observation (examination), during the observation period before the biological body of the examinee is naturally discharged, the capsule endoscope The mirror moves inside (in the body cavity) such as the stomach and small intestine with the peristaltic ...
