Abstract: A system of watching a person's blood pressure includes a database server; a network server; and a communication devices; wherein the database server is built-in with a database of blood pressure and with a software, so that a) the database server determines time for a person to measure his/her blood pressure according to medical criteria on his/her blood pressure history recorded in the database; b) the network server and the communication device notify the person to measure his/her blood pressure in advance the determined time and report his/her measured blood pressure to the network server according to the determined time; and c) the network server and the communication device remind the person of the blood pressure measurement if the network server should fail to receive his/her measured blood pressure after the determined time.

Abstract: A system of watching a person to be diagnosed/treated in time includes a database server; a network server; and a communication devices; wherein the database server is built-in with a database of vaccination and with a software, so that a) the database server determines time for a person to be diagnosed/treated according to medical criteria on his/her medical data recorded in the database; b) said network server and said communication means notify said person to be diagnosed/treated according to the determined time in advance the determined time; and c) said network server and said communication means remind said person of the diagnosis/treatment if said network server should fail to receive a confirmation of his/her diagnosis/treatment after the determined time.

Abstract: A system of watching a person's blood sugar includes a database server; a network server; and a communication devices; wherein the database server is built-in with a database of blood sugar and with a software, so that a) the database server determines time for a person to measure his/her blood sugar according to medical criteria on his/her blood sugar history recorded in the database; b) the network server and the communication device notify the person to measure his/her blood sugar in advance the determined time and report his/her measured blood sugar to the network server according to the determined time; and c) the network server and the communication device remind the person of the blood sugar measurement if the network server should fail to receive his/her measured blood sugar after the determined time.

Abstract: A system of watching a person to be vaccinated in time includes a database server; a network server; and a communication devices; wherein the database server is built-in with a database of vaccination and with a software, so that a) the database server determines time for a person to be vaccinated according to medical criteria on his/her vaccination history recorded in the database; b) said network server and said communication means notify said person or his/her proxy the determined vaccination time in advance the determined vaccination time; and c) said network server and said communication means remind said person or his/her proxy of the vaccination if said network server should fail to receive a confirmation of his/her vaccination after the determined vaccination time.
