Patent number: 7887510Abstract: The present invention relates to a device and method to control suction in a patient environment. The device comprises a body portion having an interior chamber adapted for coupling to a source of the vacuum; a valve comprising a shaft rotatably coupled to the body portion; and an actuator coupled to the shaft of the valve. In operation the valve is rotatable between i) a first position in which the vacuum is provided to the interior chamber via the valve at a first predetermined level and ii) a second position in which the vacuum is interrupted to the interior chamber. The actuator is adapted to move between a first position and a second position which increases the vacuum in the interior chamber to a second predetermined level for clearing occluded suction lines in the patient circuit.Type: GrantFiled: December 8, 2004Date of Patent: February 15, 2011Assignee: Boehringer Laboratories, Inc.Inventors: John Karpowicz, Kevin P.

Patent number: 6228056Abstract: An intermittent regulator is provided in which the regulator alternates between supplying partial vacuum to a patient for withdrawing fluids from the body of a patient, and supplying atmosphere to a patient, at a selected intermittent rate, that is adjustable upon adjusting a timing mechanism. The timing mechanism is isolated from communicating with the vacuum being drawn from a patient, separating the regulator into a “wet” side and a “dry” side. The regulator includes a piston and spool, each having magnets therein, whereby intermittent motion of the piston controls the motion of the spool and which thereby controls the opening of ports for delivery/non-delivery of vacuum to a patient. An alternative embodiment has porting for sensing occlusion in the patient line and converting the regulator from a continuous-on operation to an intermittent operation. An alternative embodiment has separate air inlet and outlet conduits to atmosphere from the “dry” side of the regulator.Type: GrantFiled: June 16, 1999Date of Patent: May 8, 2001Assignee: Boehringer Laboratories, Inc.Inventors: John R.

Patent number: 5992239Abstract: A gauge is provided, preferably for patient use, in which a piston moves linearly within a gauge body against the force of a spring. A diaphragm separates the sensing side of the piston from the clean or atmosphere side of the piston. The diaphragm rolls against the piston and the wall of the chamber during changes in pressure, and does not interfere with accuracy of the readings. Dampening is provided out of the patient fluid stream. The sight glass through which measurements are read produces an optical magnification. A baffle prevents entrained particles from the patient from entering the gauge in significant amounts. A surface-to-surface seat enables the gauge to be mounted as a saddle seat on a duct, regulator or the like.Type: GrantFiled: September 10, 1998Date of Patent: November 30, 1999Assignee: Boehringer Laboratories, Inc.Inventors: John R.

Patent number: 5879624Abstract: A container is provided that is disposable, for first collecting blood delivered from a patient, preferably by means of a vacuum draw of blood into a container, and then the blood in the container is treated. The treatment is provided by an at least partial a back-and-forth or reciprocating motion of blood along membranes, such that filtrate components of the blood pass through the membrane walls and are collected, whereby retentate components of the blood are retained, with the back-and-forth motion being provided by means of a substantially constant vacuum draw, that provides a pumping action by means of a diaphragm pump. A replenishment liquid is automatically added, substantially proportional to the amount of filtrate components of the blood that are withdrawn. The membranes are protected by a means for removing body fats or other potentially harmful materials.Type: GrantFiled: January 15, 1997Date of Patent: March 9, 1999Assignee: Boehringer Laboratories, Inc.Inventors: John R.
