Patent number: 10850089Abstract: An occlusion assembly for compressing a pair of collapsible tubes comprises a frame comprising a tubing guide configured for positioning the collapsible tube. The occlusion assembly also comprises a tubing occluder mounted to the frame with an occluding member constructed and positioned to controllably occlude or release occlusion of the collapsible tube. A door mounted to the frame is positioned to cover at least a portion of the collapsible tube and tubing occluder when closed and provide user access when open. The assembly includes a retainer mechanism engaged by the door when the door is closed to permit operation of the tubing occluder when the door is closed and retain the tubing occluder in a non-occluding configuration when the door is opened.Type: GrantFiled: June 29, 2017Date of Patent: December 1, 2020Assignee: DEKA Products Limited PartnershipInventors: Kevin L. Grant, Brett A. Rudolf, James D. Dale, Jesse T. Bodwell

Patent number: 10780213Abstract: A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.Type: GrantFiled: August 7, 2017Date of Patent: September 22, 2020Assignee: DEKA Products Limited PartnershipInventors: Kevin L.

Patent number: 10722645Abstract: A method for discharging fluid from a syringe and for mitigating occlusion conditions includes actuating the plunger of a syringe into a barrel. The method monitors fluid pressure within the barrel of the syringe and determines that an occlusion exists when the fluid pressure exceeds a predetermined threshold. The method actuates the plunger out of the barrel by a predetermined amount in response to the detected occlusion and actuates the plunger of the syringe into the barrel until a measured fluid pressure within the barrel of the syringe exceeds another predetermined threshold.Type: GrantFiled: August 10, 2017Date of Patent: July 28, 2020Assignee: DEKA Products Limited PartnershipInventors: Dean Kamen, Larry B. Gray, Jesse T. Bodwell, John M. Kerwin, Michael J. Baier, Dirk A. van der Merwe, Stephen L. Fichera, Jonathan R. Thurber, Martin D. Desch

Publication number: 20190328964Abstract: A syringe pump is disclosed that includes a body, a syringe seat, a syringe actuator, a memory, and one or more processors. The syringe seat is coupled to the body. The syringe actuator is configured to actuate a syringe secured within the syringe seat. The memory is configured to store a plurality of instructions. The one or more processors, in accordance with the plurality of instructions, is/are configured to: prime the syringe pump in a prime phase; determine if an occlusion exists during the prime phase using a first test; stop the prime phase; initiate fluid delivery into a patient; enter into a start-up phase; determine if an occlusion exists using a second test during the start-up phase; transition from the start-up phase into a steady-state phase; and determine if an occlusion exists during the steady-state phase using a third test.Type: ApplicationFiled: July 12, 2019Publication date: October 31, 2019Inventors: Martin D.

Publication number: 20180256803Abstract: A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.Type: ApplicationFiled: May 8, 2018Publication date: September 13, 2018Applicant: DEKA Products Limited PartnershipInventors: Simon C.

Patent number: 9839776Abstract: An occluder, and methods for occlusion, that employs first and second opposed occluding members associated with each other, a tube contacting member connected to, or comprising at least a portion of, at least one of the first and second occluding members, and a force actuator constructed and positioned to apply a force to at least one of the first and second occluding members. The application of the force by the force actuator may cause the tube contacting member to move between a tube occluding position and an open position. A release member may be configured and positioned to enable an operator to manually move the tube contacting member from the tube occluding position to the open position even with no force applied to the at least one of the first and second occluding members by the force actuator.Type: GrantFiled: October 24, 2014Date of Patent: December 12, 2017Assignee: DEKA Products Limited PartnershipInventors: Simon C.
