Abstract
A medical device includes an interface unit body, which is configured to hold a portion of a flexible infusion tube. A hinge insert is fixed to the interface unit body and is configured to engage a hinge receptacle, which defines a hinge axis, on an infusion pump. A catch insert is fixed to the interface unit body and is configured to lock onto a catch receptacle on the infusion pump upon rotation of the mechanical interface unit about the hinge axis while the hinge insert engages the hinge receptacle, so as to bring the tube into engagement with a peristaltic mechanism of the infusion pump in order to enable the peristaltic mechanism to propel a fluid through the tube.
Claims21
A medical apparatus, comprising:
- an infusion pump, comprising:
- a pump body;
- a peristaltic mechanism, which protrudes from the pump body and is configured to exert a force on a flexible infusion tube so as to propel a fluid through the tube;
- a hinge receptacle which is fixed to the pump body and defines a hinge axis;
- and
- a catch receptacle fixed to the pump body;
- and
- a mechanical interface unit, which is configured to hold a portion of the tube, and which comprises:
- a hinge insert, which is configured to engage the hinge receptacle;
- and
- a catch insert, which is configured to lock onto the catch receptacle upon rotation of the mechanical interface unit about the hinge axis while the hinge insert engages the hinge receptacle, so as to bring the tube into engagement with the peristaltic mechanism.

A method for infusion, comprising:
- providing a mechanical interface unit, which holds a portion of a flexible infusion tube and comprises a hinge insert and a catch insert;
- inserting the hinge insert into a hinge receptacle, which defines a hinge axis, on an infusion pump;
- rotating the mechanical interface unit about the hinge axis while the hinge insert engages the hinge receptacle, so as to bring the tube into engagement with a peristaltic mechanism of the infusion pump;
- and
- actuating the infusion pump while the tube is in engagement with the peristaltic mechanism so as to propel a fluid through the tube.
