Abstract

Disclosed is a medicine ingestion state management method capable of objectively managing medicine ingestion states of patients. The medicine ingestion state management method involves an operation of prescribing medicine (10) encapsulating, together with a medicament, a medicine information transmitting unit (20) having a function of transmitting medicine information capable of specifying a type and a quantity of the medicament to each individual patient, and an operation of grasping the medicine ingestion state of each patient by collecting the medicine information from each medicine information transmitting unit (20) in each patient.

First claim

What is claimed is:

1. A capsule comprising;
a medicament; and
an IC chip which transmits information to outside of a body of a patient who ingests the medicament, the IC chip being covered with a first material which is not dissolved within the patient's body, and
wherein the IC chip and the medicament are combined with a second material dissolvable within the patient's stomach,
wherein the IC chip is connected to an electrode in the capsule and starts a given operation using power generated by exposure of the electrode to gastric juice, and
wherein the exposure of the electrode to the gastric juice is caused by dissolution of the second material by the gastric juice.

2. The capsule according to claim 1 , wherein the IC chip transmits information indicating a type of the medicament.

3. The capsule according to claim 1 , wherein the IC chip includes a first module that counts a length of time elapsed from when the capsule dissolved within the patient's body, and a second module that transmits information calculated from the length of time which is counted by the first module.

4. The capsule according to claim 3 , wherein the first module starts counting the length of time elapsed when power is supplied to the IC chip as a result of dissolution of the capsule within the patient's stomach.

5. The capsule according to claim 3 , further comprising an electrode connected to the IC chip, wherein the electrode functions as a battery by immersion into body fluid.

6. The capsule according to claim 3 , wherein the second module transmits medicine information containing information representing a medicine effective period of the medicament.

7. The capsule according to claim 1 , wherein the IC chip includes:
a first IC chip; and
a second IC chip,
wherein the first IC chip is covered with the first material, and the second IC chip is partly covered with a second material which responds to body fluid within the patient's body.

8. The capsule according to claim 7 , wherein the first IC chip transmits first identifying information, the second IC chip transmits second identifying information, and the first identifying information and second identifying information include the same information about the medicament.

9. A capsule which can be swallowed and encapsulates a medicament, the capsule being made from a first material dissolvable within a stomach, the capsule comprising:
an IC chip covered with a second material which does not dissolve in a human body and encapsulated with the medicament in the capsule,
wherein the IC chip is connected to an electrode in the capsule and includes
a memory;
a module that writes information into the memory, wherein the module starting writing after power is supplied from the electrode to the IC chip as a result of dissolution of the capsule in the stomach; and
a transmitting module that transmits information stored in the memory, using the power,
wherein the power is generated by exposure of the electrode to gastric juice, and
wherein the exposure of the electrode to the gastric juice is caused by dissolution of the first material by the gastric juice.

10. The capsule according to claim 9 , wherein the information includes an identifier of a unit on which the IC chip is equipped.

11. The capsule according to claim 9 , wherein the memory stores information which changes from before swallowed to after swallowed.

12. A medicine ingestion state management system, comprising:
a database storing prescription information;
a combination of a medicament and an IC chip, the combination being made using a material that is soluble by gastric juice, the IC chip is connected to an electrode, and receives power generated by exposure of the electrode to the gastric juice, and the IC chip transmits medicine information using the power;
a wireless communication device configured to receive the medicine information transmitted from the IC chip;
a computer configured to determine whether or not the patient ingests the medicament as prescribed by referring to the prescription information stored in the database, based on the medicine information received from the IC chip; and
a display configured to display a result information indicating whether or not the patient ingests the medicament as prescribed,
wherein the exposure of the electrode to the gastric juice is caused by dissolution of the material by the gastric juice.
