Abstract

A device and a system for humor component detection are capable of continuously carrying out measurement with accuracy for a long time and are excellent from the aspect of good hygiene. The humor component detection system comprises the humor component detection device and an extra-corporeal sensing device. The humor component detection device comprises a biosensor, a microbe containing portion, and an outer shell. Here, the biosensor comprises a sensing element and an electronic device. The microbe containing portion includes a pouched microtube blanketing film into which the electrodes of the sensing element are inserted, a plurality of acinous polymer-filmed porous microcapsules contained inside the film, and GOD genetically-modified bacteria contained in the microcapsules.

Claims

1. A humor component detection device retained in a living body, the humor component detection device comprising:

a biosensor which is capable of measuring a humor component; and

an organism which produces a substance used in the biosensor.

2. The humor component detection device according to claim 1,

wherein the organism includes microbes.

3. The humor component detection device according to claim 2,

wherein the microbes include transgenics bacteria.

4. The humor component detection device according to claim 1,

wherein the organism is any of (A) to (C) below:

(A) cells having genetic information for autoreproduction;

(B) tissues composed of the cells; and

(C) a mixture of the cells and the tissues.

5. The humor component detection device according to claim 4,

wherein the cells are of human origin.

6. The humor component detection device according to claim 1,

wherein the organism is covered with an organism diffusion preventing film which does not permit permeation of the organism.

7. The humor component detection device according to claim 1,

wherein the biosensor includes a detecting element, which performs detection of the humor component, and is covered with an interfering substance preventing film, and

wherein the interfering substance preventing film limits permeation of interfering substances against the detection and allows permeation of the humor component.

8. The humor component detection device according to claim 1,

wherein the biosensor includes a detecting element, which performs detection of the humor component, and is covered with a produced substance diffusion preventing film,

wherein the produced substance diffusion preventing film limits permeation of substances produced by the organism and allows permeation of the humor component, and

wherein the organism is contained inside the produced substance diffusion preventing film.

9. The humor component detection device according to claim 1, further comprising:

an outer shell which houses the biosensor and the organism and permits permeation of the humor component.

10. The humor component detection device according to claim 1,

wherein the biosensor includes, as a detecting element for detecting the humor component, electrodes which is able to detect electrical signals produced when the humor component undergoes electrochemical reaction.

11. The humor component detection device according to claim 10,

wherein the electrodes are chemically modified with living body functional polymer.

12. The humor component detection device according to claim 1, further comprising:

a transmitting unit which transmits data obtained as a result of detection by the biosensor, to an outside.

13. The humor component detection device according to claim 12,

wherein the transmitting unit wirelessly communicates the data in real time.

14. A humor component detection system comprising:

the humor component detection device that is retained in a living body and includes

a biosensor which is capable of measuring a humor component,

an organism which produces a substance used in the biosensor, and

a transmitting unit which transmits data obtained as a result of detection by the biosensor, to an outside; and

an extra-corporeal monitoring device provided with a receiving unit which is capable of receiving the data transmitted from the transmitting unit.

15. The humor component detection system according to claim 14,

wherein the extra-corporeal monitoring device has a data recording unit which stores the data received together with time data.

16. The humor component detection system according to claim 14,

wherein the extra-corporeal monitoring device includes:

a determining unit which determines whether the data received is abnormal or not; and

a notifying unit which, when the data is determined to be abnormal, notifies of an anomaly.
