Abstract

A medical telemetry system includes a first detection section for detecting a first vital sign signal using a first sensor, a transmitter 10 which modulates a signal detected by the first detection section and transmits the modulated signal by radio wave transmission, a receiver 30 which receives the detection signal that has been transmitted by radio wave transmission and demodulates the received signal, having a connector 32 for transmitting the demodulated signal to a vital sign signal input section of the vital sign signal monitor 20, wherein the connector 32 of the receiver is connectable with a commonly used vital sign signal input section of each of various types of vital sign signal monitors 20.

Claims

1. A medical telemetry system, comprising:

a first sensor, adapted to be attached on a living body to detect a first vital sign signal;

a first transmitter, adapted to be connected to the first sensor and transmitting the first vital sign signal by radio wave transmission;

a receiver, receiving the first vital sign signal transmitted from the first transmitter;

a connector, integrally provided with the receiver and having a first terminal operable to output at least the first vital sign signal received by the receiver;

at least one monitor, operable to display at least the first vital sign signal; and

a connection wire, having a first end adapted to be connected to the monitor and a second end provided with a second terminal adapted to be detachably connected to the first sensor and to be detachably connected to the first terminal.

2. The medical telemetry system as set forth in claim 1, wherein the connector is detachably connected with the receiver.

3. The medical telemetry system as set forth in claim 1, wherein:

the first sensor is operable to detect a second vital sign signal; and

the first transmitter is operable to transmit the first vital sign signal and the second vital sign signal in a multiplexing manner.

4. The medical telemetry system as set forth in claim 3, wherein the receiver is operable to demultiplex the first vital sign signal and the second vital sign signal, and is operable to transmit the first vital sign signal and the second vital sign to the first terminal in a superimposing manner.

5. The medical telemetry system as set forth in claim 4, wherein the second vital sign signal is superimposed using an impedance change technique.

6. The medical telemetry system as set forth in claim 3, wherein the first vital sign signal is an electrocardiographic waveform of the living body, and the second vital sign signal is a respiratory status of the living body.

7. The medical telemetry system as set forth in claim 1, further comprising a second sensor, adapted to be attached on the living body to detect a second vital sign signal,

wherein the first transmitter is operable to transmit the first vital sign signal and the second vital sign signal in a multiplexing manner.

8. The medical telemetry system as set forth in claim 7, wherein the first vital sign signal is an electrocardiographic waveform of the living body, and the second vital sign signal is a respiratory status of the living body.

9. The medical telemetry system as set forth in claim 7, wherein the receiver is operable to demultiplex the first vital sign signal and the second vital sign signal, and is operable to transmit the first vital sign signal and the second vital sign signal to the first terminal in a superimposing manner.

10. The medical telemetry system as set forth in claim 9, wherein the second vital sign signal is superimposed using an impedance change technique.

11. The medical telemetry system as set forth in claim 1, further comprising:

a second sensor, adapted to be attached on the living body to detect a second vital sign signal; and

a second transmitter, adapted to be connected to the second sensor and transmitting the second vital sign signal by radio wave transmission, wherein;

the receiver is operable to receive the second vital sign signal transmitted from the second transmitter and to transmit the first vital sign signal and the second vital signal to the first terminal in a superimposing manner; and

the second terminal of the connection wire is further adapted to be detachably connected to the second sensor.

12. The medical telemetry system as set forth in claim 11, wherein the second vital sign signal is superimposed using an impedance change technique.

13. The medical telemetry system as set forth in claim 11, wherein the first vital sign signal is an electrocardiographic waveform of the living body, and the second vital sign signal is a respiratory status of the living body.

14. The medical telemetry system as set forth in claim 11, wherein the second terminal is provided with at least one of a hook member and a clip member.

15. The medical telemetry system as set forth in claim 1, further comprising a switch operable to cut off the output of the at least first vital sign signal from the first terminal, wherein:

the transmitter is operable to detect detachment of the first sensor from the living body; and

the switch cuts off the output of the at least first vital sign signal when the transmitter detects the detachment of the first sensor.

16. The medical telemetry system as set forth in claim 1, wherein the second terminal is provided with at least one of a hook member and a clip member.
