International Classification:

A61M 5/142
A61M 39/12
A61M 3/02

Abstract:

In one embodiment, a door is used to provide uniform pressure to insert tubing into slots of a pump having walls that are narrower than the outer diameter of the tubing. In another embodiment, connectors are attached to receptacles on the pump, where the connectors insert and/or hold the tubing in slots of the pump. The connectors push the tubing into the slots while closing thereby covering the slots, which helps assure that the tubing is properly inserted into the slots. Optionally, the tubing may be partially affixed to the connectors so that detaching the connectors from the pump receptacles may remove the tubing from the slots. In one embodiment, as long as the connectors are connected to the pump receptacles properly, the tubing is properly inserted and/or retained in the slots.

International Classification:

A61M 3/02

US Classification:

604500, 604151

Abstract:

Connectors are attached to a pump housing. The pump squeezes tubing of a particular outer diameter creating a peristaltic contraction of the tubing to push the fluid in the tubing in a particular direction. The connectors hold the tubing in slots having walls that are narrower than the outer diameter of the tubing. To aid in pushing the tubing into the slots, a door is attached to the connectors that pushes the tubing into the slots while closing thereby covering the slots, which helps assure that the tubing is properly attached to the connector. Alternatively, the connector may be permanently attached to the tubing, but may be detached from the pump housing, so that as long as the connectors are connected properly, the tubing is connected properly.
