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.

[0059] Figure 5 ~ Figure 12 Relating to embodiment 2 of the present invention, Figure 5 It is a diagram illustrating a capsule endoscope and an external device constituting a capsule endoscope device (hereinafter referred to as "in-body information acquisition system"), Figure 6 It is a diagram for explaining external devices and terminal devices constituting the in-vivo information acquisition system, Figure 7 It is a side sectional view showing the structure of Embodiment 2 of the capsule medical device, Figure 8 Is to explain the composition Figure 7 The view of the structure of the observation side cover and the opening of the capsule body shown in part A, Figure 9 Is to explain the composition Figure 7 A diagram showing the positional relationship between the side cover and the capsule body when viewing part A, Figure 10 It is a figure which shows the state which arrange|positioned the capsule main body in a mold, Figure 11 It is a figure explaining the st...

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, an ultrasonic welding machine 150 is disposed in a vacuum furnace 160, and the ultrasonic welding operation is performed in a vacuum environment.

[0095] That is, in this embodiment, as described Figure 12 As shown, for the capsule body 112 assembled on the mold 151 of the ultrasonic welding machine 150 and assembled with the tubular member 123, etc., the observation side cover 111 is arranged in a predetermined state, and the welding head 152 is placed in contact with the observation side cover. When the installation on the stepped portion 125 of 111 is completed, vacuum extraction is performed, and thereafter, 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, the expansion of th...

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-type medical device introduced into a subject to collect information in the subject, such as a swallow-type capsule endoscope, and more particularly to a capsule-type medical device maintaining high liquid-tightness, and its configuration A medical capsule casing of an exterior part of a medical capsule for 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 this capsule endoscope is that, after being swallowed by the examinee as the subject for observation (examination), the capsule endoscope The scope moves inside the stomach, small intestine, etc. (inside the body cavity) along with the peristaltic movement of the stomach, small intestine, etc., and takes pictures sequentially using the imagin...
