Wireless in-vivo information acquiring system and external device
First Claim
Patent Images
1. A wireless in-vivo information acquiring system comprising:
- a body-insertable device that is inserted into a body of a patient; and
an external device that is disposed on outside of the body of the patient, wherein the body-insertable device includes a function executing unit that executes a predetermined function to acquire in-vivo information on the body of the patient, and the external device includes a power source that outputs a power supply signal for supplying power to the body-insertable device;
a first power accumulating unit that accumulates power for driving the power source;
a second power accumulating unit that accumulates the power for driving the power source; and
a switching unit that selectively switches between the first power accumulating unit and the second power accumulating unit in such a manner that the first power accumulating unit primarily supplies power to the power source, and when a residual amount of power of the first power accumulating unit is lower than a predetermined value, the second power accumulating unit supplies the power to the power source.

Abstract
A pill inserted into a body of a patient acquires in vivo information on the body of the patient. A receiver receives the in vivo information on the body of the patient from the pill through a receiving antenna. The receiver includes batteries, and a switching circuit that switches between the batteries according to respective residual amounts of the batteries. The receiver also includes an AC power source, which allows charging of the batteries. A residual amount detecting circuit detects a residual amount of an output of the receiver, and a result of detection is informed by an informing unit.

6. A wireless in-vivo information acquiring system comprising:
-
a body-insertable device that is inserted into a body of a patient; and
an external device that is disposed on outside of the body of the patient, wherein the body-insertable device includes a function executing unit that executes a predetermined function to acquire in-vivo information on the body of the patient, and the external device includes a wireless communicating unit that performs wireless communication between the external device and the body-insertable device;
a first battery that accumulates power for driving the wireless communicating unit;
a second battery that accumulates the power for driving the wireless communicating unit, disposed separately from the first battery; and
a switching unit that selectively switches between the first battery and the second battery in such a manner that the first battery primarily supplies power to the wireless communicating unit, and when a residual amount of power of the first battery is lower than a predetermined value, the second battery supplies the power to the wireless communicating unit.
