4. The medical telemetry system according to claim 1, wherein

the transmitter is a short-range device, and

the first medical telemeter is a wireless medical telemetry device.

5. The medical telemetry system according to claim 1, wherein

the monitor apparatus is further configured to transmit the first identification code for identifying the first medical telemeter and a command indicating the operation to be performed by the first medical telemeter to the transmitter, and

the transmitter is further configured to transmit the first signal, which includes the first identification code and the command that are transmitted by the monitor apparatus.

6. The medical telemetry system according to claim 1 further comprising an external medical apparatus configured to transmit the first identification code for identifying the first medical telemeter and a command indicating the operation to be performed by the first medical telemeter to the transmitter, wherein:

the transmitter is further configured to transmit the first signal, which includes the first identification code and the command that are transmitted by the external medical apparatus.

7. The medical telemetry system according to claim 6, wherein the command is an operation instruction command for causing the first medical telemeter to transmit the second signal which includes biological information measured by the external medical apparatus or an alarm issued by the external medical apparatus, wherein

the biological information or the alarm has been transmitted from the external medical device to the first medical telemeter.

8. The medical telemetry system according to claim 1 further comprising an external medical apparatus configured to transmit a command indicating the operation to be performed by the first medical telemeter to the transmitter, wherein:

the transmitter has the first identification code for identifying the first medical telemeter, and is further configured to transmit the first signal, which includes the first identification code and the command that is transmitted by the external medical apparatus.

9. The medical telemetry system according to claim 8, wherein the command is an operation instruction command for causing the first medical telemeter to transmit the second signal which includes biological information measured by the external medical apparatus or an alarm issued by the external medical apparatus, wherein

the biological information or the alarm has been transmitted from the external medical device to the first medical telemeter.

10. The medical telemetry system according to claim 1 further comprising an antenna configured to receive the second signal, wherein

the transmitter and the antenna are integrally provided.

11. The medical telemetry system according to claim 1, wherein the transmitter is provided in the monitor apparatus.

12. The medical telemetry system according to claim 1 further comprising:

a patient information storage portion configured to store patient information for identifying a patient; and

a patient information acquiring portion configured to acquire the patient information from the patient information storage portion, wherein

the patient information acquiring portion is further configured to transmit the first identification code for identifying the first medical telemeter and the acquired patient information, to the transmitter, and

the transmitter is further configured to transmit the first signal, which includes the first identification code that is transmitted by the patient information acquiring portion and a command.

13. The medical telemetry system according to claim 12, wherein the first medical telemeter is configured to issue an alarm, in response to an indication that the patient information included in the received first signal does not coincide with patient information registered in the first medical telemeter.

14. The medical telemetry system according to claim 12, wherein

the first medical telemeter is further configured to transmit the second signal, which includes the patient information that is included in the received first signal, to the monitor apparatus, and

the monitor apparatus is further configured to issue an alarm, in response to an indication that the patient information included in the received second signal does not coincide with patient information registered in the monitor apparatus.

15. The medical telemetry system according to claim 12, wherein

the first medical telemeter is further configured to transmit the second signal, which includes the patient information that is included in the received first signal, to the monitor apparatus, and
