Patent number: 9962486Abstract: Occlusions in a delivery line of an infusion pump can be detected by measuring pressure differentials in the pump over short periods of time in order to minimize the effects of long term systematic sensor changes. In a delivery mode such as basal insulin delivery where a small portion of a volume of fluid is delivered, pressure readings can be obtained before and after the motor move to deliver each portion and compared. The differentials after one or more motor moves can be compared to determine whether an occlusion is present. In a delivery mode such as bolus insulin delivery in which an entire volume of fluid is delivered, pressure differentials can be obtained for consecutive deliveries at a common point in the delivery cycle of each delivery. Comparison of these pressure values can be used to determine whether an occlusion is present.Type: GrantFiled: November 2, 2015Date of Patent: May 8, 2018Assignee: Tandem Diabetes Care, Inc.Inventors: Michael J. Rosinko, Geoffrey A. Kruse, Paul Harris

Patent number: 9943650Abstract: A retractable self-destructing safety syringe with pre-attached needle including a barrel, an inner needle base disposed in a barrel neck at an end of the barrel body, and an elastic engagement mechanism formed between the barrel neck and the inner needle base is provided. An asymmetric elastic locking member having an elastic function is disposed at the end of the plunger, with which a sleeve-type retractable locking member on the needle base can be interlocked by the elastic function. After being retracted into the barrel body, the needle base together with the needle will be forced to deflect to one side under an asymmetric force, and the needle therefore will be forced to incline in a direction nearly a 45 degree angle toward to one side of the inner wall of the barrel and is blocked by the barrel neck, so that the needle and the needle base could not be pushed out the barrel neck again and self-destruction of the syringe is truly achieved.Type: GrantFiled: February 26, 2013Date of Patent: April 17, 2018Inventor: Zuyang Wang

Patent number: 9925336Abstract: A system for injecting a fluid medicament into a patient includes a drive mechanism, and a cassette loaded with a pre-filled hypodermic syringe. When the cassette is loaded, the syringe is held firmly inside and the cassette can be selectively engaged with the drive mechanism. The drive mechanism has two motors. A first motor initially moves the hypodermic syringe from a position inside the cassette where its needle is concealed, to a position where the needle extends from the cassette for insertion into a patient for an injection. With the needle inserted, a second motor pushes the syringe stopper to expel a fluid medicament from the syringe. After an injection, the first motor withdraws the syringe back into concealment inside the cassette, to again firmly hold the syringe on the cassette. The cassette and syringe, in combination, can then be removed from the drive mechanism and discarded.Type: GrantFiled: April 24, 2012Date of Patent: March 27, 2018Assignee: AVANT MEDICAL CORP.Inventors: John B. Slate, Michael W. Burk, Richard J. Koerner, Corey M. Magers, Andrew C. Barnes

Patent number: 9919084Abstract: A breast pump system includes a vacuum break backflow preventer for preventing breast milk from accidentally backflowing into a suction tube leading to a vacuum pump. The backflow preventer is a vacuum passageway with two spaced apart suction openings. The two openings convey air to cyclically pressurize and depressurize a small milk charging chamber. If milk accidentally covers one of the openings, air at the other opening minimizes the pressure differential that might otherwise draw the milk deep into the suction tube and toward the vacuum pump. For ease of cleaning and sanitizing, the system avoids or minimizes the use of baffles, permanently enclosed passageways, moving parts, and tight inside corners. Some passageways can be split open for access during cleaning. To make the breast milk collection device less protruding under a brassier, the vacuum passageway curves around the side of a nipple receptacle rather than in front of it.Type: GrantFiled: April 14, 2015Date of Patent: March 20, 2018Inventors: Ashia M. Pollen, Robert J. Harter

Patent number: 9884143Abstract: A medical personal-services suction handle includes a hand-graspable housing and a primary suction pathway disposed through the hand-graspable housing and having a suction line port at one end and an intake port at an opposing end thereof. An on/off valve disposed at least partially within the primary suction pathway has a user-manipulable interface by which the on/off valve selectively opens the primary suction pathway and occludes the primary suction pathway. A user-engageable pneumatic pathway serves, when selectively engaged, to pneumatically couple the primary suction pathway to a secondary external port in the hand-graspable housing such that suction is applied via the primary suction pathway to both the intake port and the secondary external port. By one approach the secondary external port comprises a thumb-control port.Type: GrantFiled: May 30, 2014Date of Patent: February 6, 2018Assignee: Medline Industries, Inc.Inventors: Michael Kobida, Michael Turturro
