Abstract

An attaching member is provided that is capable of releasing a load occurring on a pump tube that is being attached to or detached from a peristaltic pump so that the work of attaching or detaching the pump tube to or from the peristaltic pump can be performed stably. An attaching member to be attached to a blood purification apparatus including peristaltic pumps holds pump tubes to be squeezed in a predetermined direction by the peristaltic pumps for liquid delivery. The attaching member includes a body attachable to a predetermined position of the blood purification apparatus, and holding portions attached to the body and that hold the pump tubes. The holding portions are displaceable relative to the body by rocking.

Core Innovation

The invention relates to an attaching member for a blood purification apparatus including a peristaltic pump. The attaching member holds a pump tube to be squeezed in a predetermined direction by the peristaltic pump for liquid delivery. The attaching member comprises a body attachable to a predetermined position of the blood purification apparatus and a holding portion attached to the body that holds the pump tube.

The holding portion is continuous with and folded with respect to the body, and is displaceable by rocking relative to the body. The holding portion is displaceable about a folded area while holding the pump tube when the pump tube is being attached to or detached from the peristaltic pump. Additional embodiments describe anchoring of the holding portion using an anchoring part and an anchor member, and arrangements where movement of the anchor member enables attachment or detachment behavior while anchored.

Further refinements include mechanisms where rocking of the holding portion releases a load occurring on the pump tubes, expandable portions such as pantograph-like and bellows-like areas, and arrangements where holding portions or body components separate or slide relative to each other during attachment and detachment. The disclosed apparatus-level implementation also includes inlet-side and outlet-side connectors held by the holding portion, where the inlet-side connector is displaceable by a greater amount than the outlet-side connector, and a detecting unit that contacts a predetermined area to apply an urging force while preventing displacement of the holding portion caused by that urging force.

Claims Coverage

The independent claim identified is clm-00001, with dependent claims narrowing the attaching member structure and operation. The inventive features focus on a continuous folded holding portion that rocks relative to the body during pump tube attachment and detachment, anchoring-based attachment and detachment interactions, load release, differential connector displacement, and detection that prevents unintended holding-portion displacement.

The claim set covers an attaching member with a continuous folded holding portion rocking relative to a body during pump tube attachment and detachment, together with anchoring-based attachment and detachment interactions, load release by rocking, differential connector displacement between inlet and outlet sides, and a detecting unit that applies urging force while preventing unintended displacement.
