Abstract

A first detector is provided with a cuff adapted to be placed on an upper arm of a subject to detect noninvasive blood pressure of the subject. At least one second detector is adapted to be placed on a part of the subject to detect at least one vital sign of the subject. A single main body is detachably provided on the cuff while being connected with the first detector and the at least one second detector. A display is provided on the main body and operable to display the non-invasive blood pressure and the at least one vital sign as measurement data. A transmitter is provided in the main body and operable to transmit the measurement data to a receiver placed in a remote location.

Claims

1. A vital sign telemeter comprising:

a first detector comprising a cuff adapted to be placed on a first part of a subject to detect non-invasive blood pressure of the subject, and connected to a cuff hose;

at least one second detector adapted to be placed on a second part of the subject to detect at least one additional vital sign of the subject, and connected to a lead wire;

a single main body including a first connector to which the cuff hose is detachably connected, and a second connector to which the lead wire is detachably connected;

a display provided in the main body, and operable to display the non-invasive blood pressure and the at least one additional vital sign;

a transmitter provided in the main body, and operable to transmit the non-invasive blood pressure and the at least one additional vital sign to a receiver placed in a remote location;

a retainer configured to be attached to a third part of the subject to retain the main body; and

a cover configured to surround the main body, and formed with a window adapted to expose the display provided in the main body when the main body is surrounded by the cover,

wherein the first connector and the second connector of the main body are exposed to outside from the cover when the main body is surrounded by the cover.

2. The vital sign telemeter according to claim 1, wherein the retainer is wound around the third part of the subject to retain the main body.

3. The vital sign telemeter according to claim 2, wherein the third part of the subject is one of a shoulder, a waist and an arm of the subject.

4. The vital sign telemeter according to claim 1, wherein

the at least one second detector includes at least one of:

a plurality of electrodes adapted to be attached on at least one of a chest and a limb of the subject to detect one of electrocardiogram and respiration of the subject;

a sensor adapted to be attached on a finger of the subject to detect oxygen saturation in blood of the subject; and

a sensor adapted to be attached on a face of the subject to detect a concentration of carbon dioxide in gas expired through nostrils of the subject.

5. The vital telemeter according to claim 4, further comprising:

a controller configured to set an interval between periodic activation of the first detector, and configured to determine a pulse rate based on a detected pulse wave,

wherein the first detector is operable to detect the pulse wave, and

wherein the display is so configured as to simultaneously display the non-invasive blood pressure, the at least one additional vital sign, the pulse rate, the pulse wave, and the interval between periodic activation of the first detector.

6. A telemeting method, comprising steps of:

providing a first detector comprising a cuff adapted to be placed on an upper arm of a subject;

providing at least one second detector including a sensor adapted to be attached on a finger of the subject to detect oxygen saturation in blood of the subject;

connecting the first detector and the at least one second detector to a single main body which is detachably provided on the cuff;

detecting non-invasive blood pressure of the subject through the first detector;

detecting the oxygen saturation in blood of the subject through the second detector;

displaying the non-invasive blood pressure and the oxygen saturation in blood of the subject on a display provided on the main body, as measurement data;

transmitting the measurement data to a receiver placed in a remote location; and

transmitting information indicating that the measurement data for the oxygen saturation is unreliable at least while the first detector detects the non-invasive blood pressure.

7. A telemeting system, comprising:

a first detector, comprising a cuff adapted to be placed on an upper arm of a subject to detect non-invasive blood pressure of the subject;

at least one a second detector, including a sensor adapted to be placed on a finger of the subject to detect oxygen saturation in blood of the subject;

a single main body, detachably provided on the cuff while being connected with the first detector and the second detector;

a receiver, placed in a remote location from the main body and provided with an indicator; and

a transmitter, provided in the main body and operable to transmit the non-invasive blood pressure and the oxygen saturation in blood as measurement data to the receiver, wherein;

the transmitter transmits information indicating that the measurement data for the oxygen saturation is unreliable at least while the first detector detects the non-invasive blood pressure, to the receiver; and

the indicator indicates that the measurement data for the oxygen saturation received from the transmitter is unreliable when the receiver receives the information.
