Abstract
Abstract A pump for e.g. a blood- treatment apparatus, comprises a stator 14 to support a portion of a pumping tube 53 extending from a "cassette" 50 and a rotor 12 furnished with tube-compressing rollers 17, 18, 19, which may be on pivoted arms 21, 22, 23, the stator being movable perpendicularly relative to the rotor to facilitate installation of the tube. Movement of the stator may be effected by turning a cylindrical member (44), Fig. 3 (not shown), which carries an eccentric pin (42), 46 engaging with a slot 43 in the stator. <IMAGE>

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
95 words
A peristaltic pump comprising:
rotor means,
a plurality of roller means mounted to said rotor means to define a locus as said rotor means rotates,
fluid-carrying tubing in cassette means and extending therefrom,
stator means movable between an operating position wherein said tubing is forced into abutment with said locus and a loading position wherein the stator means is spaced apart from said rotor means facilitating positioning said tubing extending from the cassette means between said rotor means and said stator means, and
means for moving said stator means between said loading and operating positions.
Claim 2
Dependent Claim
95 words
A peristaltic pump comprising:
rotor means,
a plurality of roller means mounted to said rotor means to define a locus as said rotor means rotates,
fluid-carrying tubing in cassette means and extending therefrom,
stator means movable between an operating position wherein said tubing is forced into abutment with said locus and a loading position wherein the stator means is spaced apart from said rotor means facilitating positioning said tubing extending from the cassette means between said rotor means and said stator means, and
means for moving said stator means between said loading and operating positions.
Claim 3
Dependent Claim
18 words
The peristaltic pump of Claim 1, wherein said stator means moves linearly between said loading and operating positions.
Claim 4
Dependent Claim
16 words
The peristaltic pump of Claim 2 including means for maintaining the linearity of said stator movement.
Claim 5
Dependent Claim
32 words
The peristaltic pump of Claim 3, wherein said means for maintaining the linearity of said stator movement comprises a pair of slots on the stator movable on pins extending through said slots.
Claim 6
Dependent Claim
24 words
The peristaltic pump of Claim 4, wherein said slots are generally wider than said pins except at the ends thereof defining the operating position.
Claim 7
Dependent Claim
17 words
The peristaltic pump of claim 1 wherein said means for moving said stator means comprises cam means.
Claim 8
Dependent Claim
18 words
The peristaltic pump of Claim 6, wherein said cam means extends through a cam slot in said stator.
Claim 9
Dependent Claim
20 words
The peristaltic pump of Claims 4 and 7, wherein said cam slot is positioned normal to said pair of slots.
Claim 10
Dependent Claim
32 words
The peristaltic pump of Claim 1 wherein said locus is a cylinder and wherein resilient means maintain the position of said roller means removed from said rotor means to define said locus.
Claim 11
Dependent Claim
13 words
A peristaltic pump substantially as hereinbefore described with reference to the accompanying drawings.
Claim 12
Dependent Claim
13 words
A peristaltic pump substantially as hereinbefore described with reference to the accompanying drawings.
