OCCLUSIVE NON-INFLATABLE BLOOD PRESSURE DEVICE
First Claim
1. A blood pressure device comprising:
- a blood pressure cuff configured to selectively occlude and de-occlude a blood vessel of a patient without inflation of the blood pressure cuff;
an acoustic sensor configured to detect a biological sound of the patient responsive to de-occlusion of the blood vessel, the biological sound reflecting a measurement time at which a blood pressure measurement should be taken; and
a pressure sensor configured to output a pressure signal responsive to actuation of the blood pressure cuff, wherein the pressure signal at the measurement time is indicative of a blood pressure of the patient.

Abstract
A blood pressure device including a compressible material can be placed around a limb of a patient (e.g. a band or cuff). Further, the blood pressure device can include a sleeve that, at least partially, covers the compressible material and is capable of compressing the compressible material to occlude a patient'"'"'s blood vessel without inflating the sleeve. In some embodiments, the sleeve can compress the compressible material using a motor assembly. This motor assembly can include a motor and any additional mechanical devices that can be used to facilitate compressing the compressible material. For example, the motor assembly may include one or more of the following: a cable, a pulley, and a gear assembly, such as a worm drive or any other gear assembly that can facilitate compressing the compressible material.

12. A blood pressure device comprising:
-
a compressible material configured to be placed around a limb of a patient; a sleeve disposed at least partially around the compressible material and configured to compress the compressible material; and a pressure sensor configured to output a pressure signal responsive to compression of the compressible material, wherein the pressure signal is configured to reflect a blood pressure of the patient. - View Dependent Claims (13, 14, 15, 16)

17. A method for using a blood pressure device, the method comprising:
-
causing a non-inflatable blood pressure cuff to occlude a blood vessel of a patient; causing the non-inflatable blood pressure cuff to de-occlude the blood vessel subsequent to said occlusion; detecting, with an acoustic sensor, a biological sound responsive to said de-occlusion of the blood vessel; and taking a blood pressure reading responsive to detection of the biological sound. - View Dependent Claims (18, 19, 20)
