Abstract

In the medical field, it is necessary to obtain physiological parameters, including temperature, heart rate, and blood pressure, from patients frequently. The devices involved generally require human operation (for example thermometer and sphygmomanometer), or continuous direct connection to large devices. All these do not only create discomfort to the patients, but also requires operation of these devices from medical staff, which translates into substantial labor hours. To resolve these issues, RFID medical devices capable to read physiological parameters are provided, such that less human operation can be involved, or the patients may be freed from continuous connections to large devices.

Claims

1. A RFID medical device for reading at least one physiological parameter from a patient by a reader, including:

at least one sensor for sensing said physiological parameter from the patient as a corresponding at least one sensed signal;

a RFID transmitter for transmitting said sensed signal to the reader in a contactless manner, said RFID transmitter electronically and cooperatively connected to said sensor.

2. The RFID medical device of claim 1, wherein said physiological parameter is selected from the group consisting of body temperature, heart rate, and blood pressure, and said sensor is selected respectively from the group consisting of temperature sensor, heart rate sensor, and blood pressure sensor.

3. The RFID medical device of claim 2 including a plurality of said sensors for sensing a plurality of respective physiological parameters.

4. The RFID medical device of claim 1, wherein the REID transmitter has an operating voltage from 2V to 5V.

5. The RFID medical device claim 2, wherein the sensor is a heart rate sensor having an operating voltage from 2V to 7V.

6. A system for reading at least one physiological parameter from a patient including a RFID device of claim 1 and a reader.
