Abstract:
PROBLEM TO BE SOLVED: To achieve a simply-structured and highly-reliable connectivity in connection between a hemodialysis part and a line connector.SOLUTION: The blood line connector 202 for a blood circuit includes a patient access connection end 202b including a tube connection end 202a that engages with a blood circuit tube to be sealed, a male screw patient access part, and a member 202c having a female screw part that conducts fluid-tight connection. Further, the connector 202 includes a pair of locking arms 202d extending backward toward the tube connection end 202a from the member 202c, wherein each of the arms 202d has finger recess parts and thorny projection parts. The pair of locking arms 202d are configured to engage the patient access connection end 202b by locking it using a fitting connector of the hemodialysis part and the thorny projection parts when press-fit connection is conducted, and engagement of the thorny projection part with the fitting connector is released when each of the finger recess parts are biased.

PROBLEM TO BE SOLVED: To achieve highly reliable connectability between a hemodialysis part and a line connector with simple configuration.SOLUTION: An three-prongs reagent supply connector system includes a connector (491) comprising three parallel prongs: first and second outer prongs arranged in a common plane; and a center prong arranged above the common plane. The first prong is provided to be connected in fluid communication with an outlet of a first container (28) for a first reagent via a first supply line (492); the second prong is provided to be connected in fluid communication with a second container for a second reagent via a second supply line (494); and the center prong is provided to be connected in fluid communication with an inlet of the first container (28) via a center supply line (493). The three parallel prongs of the connector (491) are provided so that: the connector may help prevent the improper connection to a connection point of the hemodialysis unit; and connection in only one direction of the connector (491) to corresponding receiving holes of the connection point can be made.
Abstract:
A pill dispenser includes a housing, a pill-dispensing mechanism, a receptacle, a pill-viewing camera, an identifying camera, one or more processor, and a storage medium (e.g., a memory). The pill-dispensing mechanism is coupled an opening of the housing. The first pill-viewing camera is positioned to capture an image of the receptacle, and the identifying camera is positioned to capture an image of an area adjacent to the housing. The one or more processors are in operative communication with the pill-dispensing mechanism, the pill-viewing camera, and the identifying camera. The storage medium stores processor executable instructions for: instructing the pill-dispensing mechanism to dispense a pill; instructing the pill-viewing camera to capture a first image of the pill to determine a presence of the pill; instructing the pill-viewing camera to capture a second image to determine an absence of the pill; and instructing the identifying camera to capture a third image.
Abstract:
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.

Abstract:
An enclosure for containing a hemodialysis unit includes a housing suitable to support components for performing hemodialysis including a dialyzer, one or more pumps to circulate blood through the dialyzer, a source of dialysate, and one or more pumps to circulate the dialysate through the dialyzer. The housing may have a front panel at which blood circuit connections and dialysate fluidic connections are located, e.g., blood line connections for patient blood access, connections for a reagent supply, dialyzer connections for both blood flow and dialysate, etc. The enclosure may also include a pair of vertical, side-by-side doors hingedly mounted to the housing. With the doors in the closed position, access to the patient access and dialysate fluidic connections may be blocked, and the doors may allow for the retention of heat in the housing suitable for disinfection during a disinfection cycle.
Abstract:
Attorney Docket: L50WO 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.

Abstract:
There is provided a hemodialysis and similar dialysis system. The system includes a method for removing air or other undissolved gas from a flow of blood in a dialysis unit, comprising providing an air trap in a blood flow circuit of a dialysis unit, the air trap having a container with an inlet port located at a top of the container and an outlet port at a bottom of the container, the air trap being arranged to remove air from blood flowing from the inlet port to the outlet port and introducing blood into the container via the inlet port of the air trap such that the blood flows from the inlet port to the outlet port of the container and further removing air from blood flowing in the air trap and trapping the air in the air trap and causing flow of fluid from the outlet port to the inlet port of the air trap so as to remove the trapped air from the container.
