Abstract

A recording medium includes a sensor circuit unit generating a current in accordance with a blood glucose level in blood, and a control unit calculating blood glucose level data from the data obtained by digital conversion of the generated current at signal processing unit, writing the calculated data to an EEPROM as a memory unit, reading the blood glucose level data from EEPROM and transmitting the same to a portable terminal on which recording medium is mounted, through a communication control unit. The recording medium further includes a power supply control unit receiving power from the portable terminal on which the recording medium is mounted, and supplying power to various portions in the recording medium. As a result, the recording medium can be utilized, when mounted on the portable terminal, a blood glucose monitoring apparatus, and the recording medium can be used in a system for providing bi-directional service between the portable terminal and a server managing the blood glucose information received from the portable terminal connected by a network.

Claims

1. A remote medical system, comprising:

a network through which bi-directional communication is allowed;

a first portable terminal connected to said network through a wireless base station;

a recording medium operating mounted on said first portable terminal; and

a server connected to said network;

wherein

said recording medium includes

a first communication control unit exchanging data with said first portable terminal,

a sensor circuit unit generating a current in accordance with a blood glucose level of taken blood,

a signal processing unit converting said generated current to a digital data and outputting the data,

an electrically erasable and programmable non-volatile memory unit storing blood glucose level data converted based on the data output from said signal processing unit,

a first control unit converting the data output from said signal processing unit to said blood glucose level data, writing the converted data to said memory unit, reading said blood glucose level data from said memory unit and transmitting the data to said first portable terminal through said first communication control unit, and

a power supply control unit receiving power from said first portable terminal and supplying power to said sensor circuit unit, said signal processing unit, said memory unit, said first communication control unit and said first control unit,

said first portable terminal transmits said blood glucose level data to said server through said wireless base station and said network, and

said server manages said blood glucose level data transmitted from said first portable terminal in association with customer information and transmits information on said blood glucose level data to said first portable terminal through said network and said wireless base station.

2. The remote medical system according to claim 1, wherein

said first portable terminal includes

a second communication control unit exchanging data with said recording medium,

a power supply unit supplying power to said recording medium,

a third communication control unit exchanging data with said wireless base station, and

a second control unit controlling said second and third communication control units.

3. The remote medical system according to claim 1, wherein

when said recording medium measures said blood glucose level, said first portable terminal obtains blood glucose level data corresponding to the measured blood glucose level from said recording medium and automatically transmits the blood glucose level data to said server through said wireless base station and said network.

4. The remote medical system according to claim 1, further comprising:

a second portable terminal owned by a physician or a medical institution having a contract in advance and connected to said network; and

a third portable terminal owned by a hospital and connected to said network;

wherein

said second and third portable terminals carry out data communication with said server and said first portable terminal through said network based on said blood glucose level data transmitted from said first portable terminal to said server.

5. The remote medical system according to claim 1, further comprising a fourth portable terminal owned by an advertiser serving to provide information on a medical product or medical equipment or to provide advertisement of a company manufacturing and marketing a medical product or medical equipment and connected to said network;

wherein

said fourth portable terminal carries out data communication with said server and said first portable terminal through said network.

6. The remote medical system according to claim 1, wherein said sensor circuit unit includes an enzyme electrode and generates a current in accordance with said blood glucose level from enzyme reaction between glucose in said taken blood and enzyme fixed to said enzyme electrode.

7. The remote medical system according to claim 1, wherein

said recording medium further includes an inlet port for inserting test paper for mounting said test paper on which said taken blood is applied.

8. The remote medical system according to claim 1, wherein

said first portable terminal displays said measured blood glucose level data.
