Abstract

A continuous analysis apparatus capable of transmitting information about components in body fluid to another apparatus such as medicine dosing apparatus more correctly without giving a user displeasure. The continuous analysis apparatus according to the present invention includes a sensing unit 2 including a sensor that is held in subcutaneous tissue for obtaining information with respect to an objective substance in a sample; and a data holding unit 3 having a storage means for storing the information obtained from the sensor or data corresponding to the information, the sensing unit and the data holding unit having configuration so that they are separably joined to each other.

Claims

1. A continuous analysis apparatus comprising:

a sensing unit including a subcutaneous sensor for obtaining information with respect to an objective substance in a sample,

a power supply for supplying power to the sensor,

a data storage part for storing information obtained from the sensor; and

a data holding unit joined to or alternatively, separated from the sensing unit, the data holding unit including a storage means, and

a control part, included in the data holding unit, for performing, when the data holding unit is joined to the sensing unit, control of storing the information stored in the data storage part of the sensing unit or data corresponding to the information stored in the data storage part of the sensing unit into the storage means and performing, when the data holding unit is separated from the sensing unit and joined to an external apparatus, control of transmitting to the external apparatus the information stored in the storage means,

wherein the sensing unit and the data holding unit each comprise a data communication unit for transmitting data from the sensing unit to the data holding unit or from the data holding unit to the sensing unit, and

wherein the external apparatus comprises a data communication unit configured for transmitting data from the external apparatus to the data holding unit or from the data holding unit to the external apparatus via their respective communication units.

2. The continuous analysis apparatus according to claim 1, wherein the sensing unit and the data holding unit each comprise an engaging means for separably joining the data holding unit to the sensing unit.

3. The continuous analysis apparatus according to claim 1, wherein the data communication units of the sensing unit and the data holding unit transmit the data when the sensing unit and the data holding unit are not in contact with each other.

4. The continuous analysis apparatus according to claim 1, wherein the data communication units of the sensing unit and the data holding unit each comprise connector units, wherein the connector units transmit the data when the sensing unit and the data holding unit are in contact with each other.

5. The continuous analysis apparatus according to claim 4, wherein each connector unit is placed in one engaging means, and

the data is transmitted by joining the data holding unit to the sensing unit.

6. The continuous analysis apparatus according to claim 4, wherein each engaging means is placed in one connector unit, and

the data holding unit is joined to the external apparatus by bringing the data holding unit and the external apparatus into contact.

7. A control system comprising the continuous analysis apparatus according to claim 1 and the external apparatus, wherein

the external apparatus has a storage means for storing the information from the data holding unit, and

the data holding unit and the external apparatus are joined together or alternatively, separated from each other.

8. The control system according to claim 7, wherein the external apparatus and the data holding unit each comprise an engaging means for separably joining the data holding unit to the external apparatus.

9. The control system according to claim 7, wherein the data communication units of the external apparatus and the data holding unit transmit the data when the external apparatus and the data holding unit are not in contact with each other.

10. The control system according to claim 7, wherein the data communication units of the external apparatus and the data holding unit each comprise a connector unit, wherein the connector units transmit the data when the external apparatus and the data holding unit are in contact with each other.

11. The control system according to claim 10, wherein each connector unit is placed in one engaging means, and

the data is transmitted by joining the data holding unit to the external apparatus.

12. The control system according to claim 10, wherein each engaging means is placed in one connector unit, and

the data holding unit is joined to the external apparatus by bringing the data holding unit and the external apparatus into contact.

13. The control system according to claim 7, wherein the external apparatus connector unit is installed in the engaging means, wherein the external apparatus is a medicine dosing apparatus for dosing medicine into a body, an information processing apparatus for managing information related to a sample component, or a display unit for displaying a concentration of a sample component.
