Publication number: 20170202538Abstract: Devices and method are provided for ultrasound transmission without the need for external couplants, such as gels, which are typically used in conventional ultrasound procedures. In particular, ultrashields are provided for use with ultrasound probes, wherein the ultrashields have specialized layers to provide an uninterrupted pathway of acoustic conductance from the probe to the surface of the body throughout the procedure while introducing minimal to no attenuation of ultrasound wave transmission. In addition, combinations of ultrashields and probe covers are provided to provide additional features such as a microbial barrier.Type: ApplicationFiled: March 31, 2017Publication date: July 20, 2017Applicant: HealthCare Evolution LLCInventors: Siddharth DESAI, Jerry JONES

Patent number: 9649434Abstract: A patient controlled liquid drug administration device providing either or both of a continuous flow of a liquid drug, as well as successive boluses thereof, to be self-administered by a patient while allowing delivery of only full bolus volumes. The device includes a reciprocating pump defining a closed internal reservoir having a fixed first wall, and a second, flexible wall that is axially movable in relation to the fixed wall between reservoir-full and reservoir-empty positions. A lock is connected to a push button that activates a plunger of the pump. The lock has a first position preventing the push button from being depressed when the push button is in an extended position and the plunger is in a reservoir-empty position and a second position permitting the push button to be depressed when the push button is in an extended position and the plunger is in a reservoir-full position.Type: GrantFiled: June 15, 2015Date of Patent: May 16, 2017Assignee: Avent, Inc.Inventors: Quang Ngoc Vu, Siddharth Desai, Giuseppe Sacca
