Portable peristaltic pump
First Claim
1. A portable peristaltic pump comprising:
- a rotor (109) equipped with at least one turning roller (110),a means for driving (111,
112) said rotor,a means for controlling (113) said driving means,a support piece equipped with a rounded-off part (308) arranged in a substantially concentric manner to the rotor, wherein during operation said at least one turning roller compresses a flexible tubing (202) against the rounded-off part (308), wherein said flexible tubing (202) is connected to a liquid reservoir (210), anda means for turning said rotor by an external action to affect discharge from the tubing, wherein the rotor comprises two concentric superimposed parts and an engaging-disengaging means, wherein the first part is connected to said means for driving and the second part carries said at least one turning roller;
wherein the engaging-disengaging means engages the first and second parts, during normal operation, to enable rotation of the second part by the means for driving,wherein the engaging-disengaging means automatically disengages the first and second parts when the second part of said rotor is put into rotation through the means for turning by external action.

Abstract
The invention concerns a peristaltic pump comprising a rotor (109) provided with three turning rollers (110), means for driving the rotor, a support piece with a rounded portion arranged substantially concentric to the rotor and against which the rollers, when operating, come to compress a flexible pipe connected to a reservoir of liquid to push it outwards and means for turning said rotor by external means to air bleed the pipe. The rotor (109) is made of two concentric superposed parts the first (115) of which is coupled with drive means and the second (122, 123) bears the rollers. The rotor further comprises engaging-disengaging means (118, 120) whereby: when operating normally, its two parts co-operate for its rotation by its drive means; when it is rotated by external means, said parts are automatically disengaged. The invention is useful for subcutaneous or intravenous injection of medicinal solutions.

12. A portable peristaltic pump comprising:
-
a rotor (109) equipped with at least one turning roller (110), a driver (111,
112) of said rotor,a controller (113) of said driver, a support piece equipped with a rounded-off part (308) arranged in a substantially concentric manner to the rotor, wherein said at least one turning roller compresses a flexible tubing (202) against the rounded-off part (308), wherein said flexible tubing (202) is connected to a liquid reservoir (210), and a turner of said rotor by an external action to affect discharge from the tubing, wherein the rotor comprises two concentric superimposed parts and a clutch, wherein the first part is connected to said driver and the second part carries said at least one turning roller; wherein the clutch engages the first and second parts, during normal operation, to rotate the second part by the driver, wherein the clutch automatically disengages the first and second parts when the second part of said rotor is turned by said turner by an external action. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
