Problems solved by technology

Due to the capacity of the built-in battery, the number of photographs will be limited, and the introduction of the drive mechanism will also be limited.
In addition, small batteries that are generally used cannot be disposed of as simple non-combustible garbage, so after being discharged out of the body for recycling, the batteries are taken out of the capsule endoscope and disposed of separately

no. 1 Embodiment approach

[0054] First, the concept of the power supply system of the present invention will be described. Figure 1A It is a diagram showing the appearance structure of the ingestion-type medical capsule device (hereinafter referred to as the capsule device) in the state of being injected into the living body according to the first embodiment of the present invention. Figure 1B is shown along Figure 1A The diagram of the cross-sectional structure of the capsule device in the A-A direction of . also, figure 2 is a diagram showing a schematic configuration of a power supply system. image 3 shows along the Figure 1A The cross-sectional shape of the electrode of the first modified example in the direction AA of .

[0055] In the description below, the digester contents refer to all substances contained in the digester that function as electrolytes or electrolyte solutions. Specifically, it is a mixture of digestive secretions such as saliva and gastric juice secreted from the mouth,...

no. 2 Embodiment approach

[0106] Next, a capsule device equipped with a power supply system according to a second embodiment will be described.

[0107] Figure 8 An example of the appearance and structure of a capsule device mainly used for working in the duodenum and small intestine is shown. Here, regarding the structural parts of the present embodiment, the same structural parts as those of the above-mentioned first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

[0108] As a power supply system mounted on the capsule device 1, an electrode 22 made of aluminum serving as a cathode and an electrode 23 made of carbon serving as an anode are formed on the wall surface of the capsule main body 5, forming a circuit that stores the contents of the digester. Voltaic battery as electrolyte. The above-mentioned power supply unit 6 is arranged inside the capsule body 5 and is connected by wires. In addition, the entire surface of the electrode 21 is covered...

no. 3 Embodiment approach

[0114] Next, a capsule device equipped with a power supply system according to a third embodiment will be described.

[0115] Figure 9 A cross-sectional structure of a capsule device that works primarily in the large intestine is shown. Here, regarding the structural parts of the present embodiment, the same structural parts as those of the above-mentioned first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

[0116] The power supply unit 6 (not shown) of the power supply system in the capsule device 1 has the same configuration as that of the above-mentioned first embodiment.

[0117] In the capsule device 1 of the present embodiment, an electrode 22 made of aluminum serving as a cathode and an electrode 23 made of carbon serving as an anode are formed on the outer surface of the capsule main body 5, so that the digester contents are used as an electrolyte solution. Voltaic battery. It is the same as the electrode in the ab...

Abstract

Provided is a power generation system that does not restrict patient's area of activity, is harmless to a living body, and can obtain a sufficient amount of electric power in the stomach or bowel, and also is provided a disposable medical capsule device that is mounted with the power generation system and does not need to be collected after being used. The power generation system is mounted in the capsule device, includes at least two electrodes or a pair of electrodes consisting of an aluminum electrode and a catalyst-supported carbon electrode which are provided on the outer wall surface of the capsule main body, is immersed in an electrolyte solution consisting of stomach fluid or bowel fluid to generate electricity, and supplies the power supply to a constituent region in the capsule device.

Description

technical field [0001] The present invention relates to an ingestible medical capsule device equipped with a power supply system that generates electricity using the contents of a digestive system in a living body, and performs surrounding information detection and medical treatment when shed in a living body. Background technique [0002] In recent years, various medical capsule devices formed in a capsule shape have been known. As such a capsule device, a representative capsule endoscope mounts an imaging mechanism and a battery in a capsule, and drives the imaging mechanism with the battery to perform imaging. Due to the capacity of the built-in battery, the number of photographs will be limited, and the introduction of the driving mechanism will also be limited. In addition, small batteries that are generally used cannot be disposed of as simple non-combustible garbage. Therefore, after being discharged out of the body for recycling, the batteries are taken out of the c...
