Abstract

A device and method for measuring blood pressure are provided. More particularly, a non-invasive device utilizing an ultra-sound transducer and a conventional blood pressure cuff are used, in combination, to measure blood pressure.

Claims

1. A system for monitoring the blood pressure of a patient, comprising:

a blood pressure cuff located around the arm of the patient;

an ultrasound transceiver located in communication with the blood pressure cuff;

a processor for receiving and processing information from the ultrasound transceiver, said processor triggering the operation of said blood pressure cuff when information received from the ultrasound transceiver indicates a blood pressure of the patient exceeds a preset threshold value.

2. The system of claim 1, wherein the ultrasound transceiver is located on the blood pressure cuff.

3. The system of claim 1, wherein the ultrasound transceiver is removably connected to the blood pressure cuff.

4. The system of claim 1, wherein said processor uses the ultrasound information to determine at least one characteristic of the patient'"'"'s artery and wherein said threshold is adjusted based on said at least one characteristic.

5. The system of claim 4, wherein said threshold is manually adjusted.

6. The system of claim 4, wherein said threshold is automatically adjusted by said processor.

7. A method for monitoring the blood pressure of a patient, comprising the steps of:

providing a blood pressure cuff located around the arm of the patient;

providing an ultrasound transceiver located in communication with the blood pressure cuff;

processing information from the ultrasound transceiver; and

triggering the operation of the blood pressure cuff when information received from the ultrasound transceiver indicates a blood pressure of the patient exceeds a preset threshold value.

8. The method of claim 7, further comprising the step of triggering an alarm if the blood pressure measured by the blood pressure cuff exceeds a second preset threshold.

9. The method of claim 7, further comprising the steps of:

determining, from the ultrasound information, at least one characteristic of the patient'"'"'s artery; and

adjusting the threshold based on the at least one characteristic.
