Patent number: 11372103Abstract: A method includes receiving first electrical signals from a first single-element transducer (1121) and second electrical signals from a second single-element transducer (1122). The transducers are disposed on a shaft (110), which has a longitudinal axis (200), of an ultrasound imaging probe (102) with transducing sides disposed transverse to and facing away from the longitudinal axis. The transducers are angularly offset from each other on the shaft by a non-zero angle. The transducers are operated at first and second different cutoff frequencies. The shaft concurrently translates and rotates while the transducers receive the first and second ultrasound signals. The method further includes delay and sum beamforming, with first and second beamformers (1201, 1202), the first and second electrical signals, respectively via different processing chains (7121, 7122), employing an adaptive synthetic aperture technique, producing first and second images.Type: GrantFiled: March 1, 2016Date of Patent: June 28, 2022Assignee: B-K MEDICAL APSInventors: Svetoslav Ivanov Nikolov, Jens Munk Hansen

Patent number: 9358336Abstract: Drug delivery device with electronically controlled and axially displaceable piston drive member (10) adapted to engage a loaded cartridge piston. The piston drive member is moveable between a proximal loading position in which a cartridge can be received and a distal loaded position in engagement with the piston. A proximity sensor (11,12) provides a varying output indicative of a varying distance between the piston drive member and the piston. A controller (30) coupled to the proximity sensor is configured to control movement of the piston drive member from the loading position to the loaded position and stop movement when the controller based on input from the proximity sensor system determines that the loaded position has just been reached. By this arrangement it is prevented that a drug-filled cartridge is pressurized during the loading and initializing procedure.Type: GrantFiled: March 26, 2013Date of Patent: June 7, 2016Assignee: Novo Nordisk A/SInventors: Jens A.

Publication number: 20070244412Abstract: The invention relates to an apparatus for self-treatment of diabetes. The apparatus is particularly advantageous by comprising a plurality of devices each of which has its own dedicated function corresponding to a number of acts which a diabetic must perform on himself. The individual devices are mutually interconnectible, and the combination comprises at least a body fluid analyser and a dosing apparatus for administering a predetermined dose of insulin to the patient. Each of the devices may be provided in several sizes so that the user himself may combine the relevant devices of the relevant size with respect to the current need. This reduces the risk of forgetting parts of the equipment, and the confidence of using the equipment is enhanced because it is evident to the user that it is a complete apparatus consisting of unified parts.Type: ApplicationFiled: April 16, 2007Publication date: October 18, 2007Inventors: Steffen Lav, Jens Munk, Brian Ritsing
