Problems solved by technology

Specifically, for example, in the case of the first example, if the magnet is not set in a state close to the capsule body at all times, it cannot be kept off, so it is inconvenient to handle when the capsule body does not need to be connected, for example, to clean the capsule body.
[0007] That is, in the case where the capsule body does not need to be connected for cleaning, etc., since the magnet must be set close to the capsule body, it is inconvenient to handle

no. 1 Embodiment approach

[0028] Figure 1 to Figure 3 Regarding the first embodiment of the present invention, figure 1 shows the internal structure of the capsule medical device according to the first embodiment, figure 1 (A) represents a longitudinal section, figure 1 (B) use figure 1 The A-A section of (A) shows the structure of the switch substrate, figure 2 Indicates the circuit structure of the switching circuit, image 3 This is a schematic structure for explaining the operation of the capsule medical device.

[0029] Such as figure 1 As shown in (A), in the capsule medical device 1 according to the first embodiment of the present invention, the cylindrical capsule main body (hereinafter, simply referred to as the main body) 2 is covered by the transparent and hemispherical front end cover 3 The front end of the main body 2 is covered by a rear cover 4 with rounded corners to form a capsule container sealed by a watertight structure, and a camera unit is built in as described below.

no. 2 Embodiment approach

[0064] Next, refer to Figure 4 and Figure 5 A second embodiment of the present invention will be described. Figure 4 A schematic configuration of a capsule medical device 1B according to a second embodiment of the present invention is shown. In this capsule medical device 1B, a switch circuit 34B has only one sensor, for example, only a reed switch 32 .

[0065] Figure 5 The specific circuit structure of the switch circuit 34B of this embodiment is shown. Such as Figure 5 As shown, the anode of the power supply 35 is connected to one input terminal of the AND gate 41 constituting the switch circuit 34B, and is connected to the power supply terminal Vcc of the D-type flip-flop 42 . And, this positive electrode is connected to 6ND through a resistor R and a reed switch 32 connected in series thereto.

[0066] In addition, the connection point of the resistor R and the reed switch 32 is connected to the clock input terminal CLK of the flip-flop 42, and the inverted outp...

no. 3 Embodiment approach

[0075] Next, a third embodiment of the present invention will be described.

[0076] The configuration of the third embodiment is obtained by modifying the first embodiment described above.

[0077] exist Figure 6 The main part of the capsule medical device 1C of the third embodiment is shown in . In this embodiment, the switch circuit 34C for power supply / blocking is formed by, for example, two photosensors 31a and 31b, and a shielding member 45 for shielding light (shielding light) is arranged between the two photosensors so that Light that is on or off on one side will not be incident on the other.

[0078] This embodiment has substantially the same effect as the first embodiment, and since the same type of sensor is used, the cost can be reduced. In addition, at the time of turning on and off, the on and off states can be controlled by one type of light emitting unit, so that the convenience can be improved.

[0079] Figure 7 express Figure 6 This is the first mod...

Abstract

A capsule type medical device includes: a capsule-shaped external member; a sensor capable of sensing a physical amount change caused outside of the external member in a non-contact manner; and a switch circuit performing at least one of two controls arranged inside the external member: a first control for switching energy supply from a battery to an electric circuit from ON to OFF and a second control for switching the energy supply from OFF to ON according to a temporary change of the physical amount detected by the sensor. The state of energy supply switched by these controls can be maintained until the sensor detects the next physical amount change.

Description

technical field [0001] The present invention relates to a capsule-shaped medical device for examining the inside of a living body and the like in a capsule shape. Background technique [0002] PCT WO 01-35814A1 discloses an example of image acquisition as an example of a capsule-type medical device that performs inspections of the inside of a living body in a capsule shape that is easy for a patient to swallow. [0003] In this example (first example), the capsule main body for image acquisition is covered by the casing before use. A magnet is installed on the side of the housing. When used for image acquisition, the capsule body can be taken out from the housing and separated from the housing. The magnetic force of the magnet can be used to set the switch circuit from off to on. [0004] In addition, Japanese Patent Laid-Open Publication (Patent No. 2849131) cites an example of ultrasonic diagnosis as another example of the capsule medical device. [0005] In this example...
