1. An ultrasound patch configured for detecting fluid flow in a vessel in a patient, comprising:
a flex circuit;
first and second transducer elements connected to the flex circuit, the flex circuit hinged to angularly position the first and second transducer with respect to each other;
control electronics coupled to the first and second transducer elements through the flex circuit;
a battery coupled to the control electronics;
a housing containing the flex circuit, the first and second transducer elements, the control electronics and the battery, the housing comprising opposing top and bottom surfaces, the housing configured to be secured to skin of the patient over the vessel with the top surface facing away from the patient's skin, and the bottom surface configured to face toward the patient's skin and toward the vessel patient during use with the patient; and
a frame securely retained in a fixed position within the housing, the frame supporting the first and second transducer elements at an angular orientation relative to each other.
