Abstract

The present teaching provide an attaching member that is attachable to a blood purification apparatus that includes peristaltic pumps. The attaching member holds pump tubes that are squeezed in a predetermined direction by the respective peristaltic pumps to deliver liquid. The attaching member includes a body that is attachable to a predetermined position of the blood purification apparatus. A holding portion is attached to the body and holds the pump tubes. The body has openings that house the flexible tubes, the flexible tubes allow liquid to flow therethrough, and the flexible tubes are securable by being passed through the openings.

Core Innovation

The invention relates to an attaching member configured to be attached to a blood purification apparatus that includes peristaltic pumps. The attaching member holds pump tubes to be squeezed in a predetermined direction by one of the peristaltic pumps to deliver liquid, and includes a body attachable to a predetermined position of the blood purification apparatus and a holding portion attached to the body that holds the pump tubes.

The holding portion includes first holding portions on a first edge of the body and second holding portions on a second edge of the body, so that connectors of the pump tubes are held in an inclined state by holding portions attached at two respective sides of the body. The body has openings provided in pairs, spaced apart, through which flexible tubes configured to allow liquid to flow through are allowed to pass, and the flexible tubes are securable by being passed from a first of the pair of openings in the body to a second of the pair of openings in the body.

The openings are formed in a central portion of the body positioned between the first holding portions and the second holding portions, and the pairs of openings are each a hole that penetrates through a portion of the body. In some configurations, the body includes slits connecting corresponding pairs of the openings, and lids cover one or more of the openings so that the flexible tubes pass through the openings when the lids are moved relative to the openings.

Claims Coverage

The document includes two independent claims covering an attaching member for a blood purification apparatus with peristaltic pumps. The claims center on a body with first and second edge holding portions that hold pump-tube connectors in an inclined state, together with central openings for flexible tubes, and one claim further recites lids that cover the openings and move relative to them.

Inclined-state edge holding for pump-tube connectors

First holding portions on a first edge of the body and second holding portions on a second edge of the body hold connectors of the pump tubes in an inclined state.

Paired central through-openings for flexible tubes

The body has openings provided in pairs, spaced apart, through which flexible tubes configured to allow liquid to flow through are allowed to pass, and the flexible tubes are securable by being passed from a first of the pair of openings in the body to a second of the pair of openings in the body.

Lids covering central openings

Lids cover one or more of the openings, and the flexible tubes are configured to pass through the openings when the lids are moved relative to the openings.

Central openings between edge holding portions

The openings are formed in a central portion of the body positioned between the first holding portions and the second holding portions.

Overall, the claims cover an attaching member that holds pump-tube connectors in an inclined state using first and second edge holding portions and routes flexible tubes through central openings between those holding portions, with a variant in which lids cover the openings and allow tube passage when moved.

Stated Advantages

Documented Applications

A connected blood purification circuit is exemplified, including extracorporeal blood circulation and flow routes for introducing substitution fluid or dialysate and for draining waste liquid from a connected blood purifier to the attaching member and pump tubes.
