Abstract
An attaching member attachable to a blood purification apparatus including a peristaltic pump, the attaching member holding a pump tube to be squeezed in a predetermined direction by the peristaltic pump for liquid delivery. The attaching member includes a body attachable to a predetermined position of the blood purification apparatus, and a holding portion attached to the body and that holds the pump tube. The holding portion holds the pump tube such that the pump tube is inclined in a direction in which the pump tube is attached to the peristaltic pump.
Core Innovation
An attaching member is attached to a blood purification apparatus including a peristaltic pump, and holds a pump tube to be squeezed in a predetermined direction by the peristaltic pump for liquid delivery. The attaching member includes a body attachable to a predetermined position of the blood purification apparatus and a holding portion attached to the body and holding the pump tube, wherein the holding portion holds the pump tube such that the pump tube is inclined, relative to the body, in a direction in which the pump tube is attached to the peristaltic pump.
The holding portion extends in an inclined state and holds a connector formed at both ends of the pump tube. The holding portion is connected to a flow route, and the holding portion extends continuously or extends in an inclined state relative to the body. The holding portion is formed with a resin molded component that is formed continuously, and is attachable at an inclined state to the body by folding at folds extended along boundaries between the body and the holding portion.
The attaching member further provides mechanical behavior for attaching and detaching, including holding portions that are displaceable and rockable about folds under load during attaching or detaching. The holding portion is provided with anchoring holes and is engageable with anchor members so that anchoring enables attachment and detachment by moving the anchor members.
Claims Coverage
The independent claims define an attaching member for a blood purification apparatus with a peristaltic pump that holds and positions a pump tube in an inclined direction toward the pump, and further specify resin-molded/folding, body/holding geometry, connector, flow-route connection, and anchoring/displaceability features (4 independent claims).
Inclined pump tube attaching in direction of peristaltic pump attachment
The attaching member includes a body attachable to a predetermined position and a holding portion attached to the body and holding the pump tube, wherein the holding portion holds the pump tube such that the pump tube is inclined, relative to the body, in a direction in which the pump tube is attached to the peristaltic pump and the holding portion extends in an inclined state.
Inclined state attachment via continuously formed resin molded component and folding at folds
The holding portion is formed with a resin molded component that is formed continuously, and the holding portion is attachable at an inclined state to the body by folding at folds extended along boundaries between the body and the holding portion.
Inclined surfaces on the body to incline the holding portion
The body includes inclined surfaces that the holding portions attach to so that the pump tube is inclined in the direction in which the pump tube is attached to the peristaltic pump.
Connector-at-both-ends pump tube held in inclined state connected to flow route
The holding portion holds a connector formed at both ends of the pump tube and the holding portion is connected to a flow route, where the holding portion extends in an inclined state.
Across the independent claims, the inventive core is an attaching member that holds a pump tube so the pump tube is inclined relative to the body in the direction of attachment to the peristaltic pump, including connector and flow-route connection, and further geometry and construction features such as resin-molded continuously formed components with folding at folds and body inclined surfaces that support the inclined holding portion.
Stated Advantages
Documented Applications
A connected blood purification circuit with dialysate or substitution-fluid introduction lines and a drain-liquid discharge line is described for blood purification treatment.
