Automatic safety occluder
First Claim
Patent Images
1. A system for selectively controlling flow through an infusion tube comprising:
- a pump having a body and a pumping mechanism;
a recess formed in the pump body for receiving an occluder of an infusion set;
an electric solenoid disposed in communication with the recess;
an infusion set having a tube for delivering a fluid and an occluder disposed thereon; and
wherein the infusion set is mounted in the pump such that the tube engages the pumping mechanism and such that the occluder is positioned in the recess such that actuation of the solenoid actuates the occluder to selectively allow flow through the tube; and
wherein the solenoid is formed as part of an infusion pump, and wherein the occluder is disposable in the infusion pump adjacent the solenoid such that actuation of the solenoid actuates the occluder.

Abstract
An automatic safety occluder provides an occluder for an infusion set that is biased in a closed position until an electrical signal is received that causes the occluder to open. Should the occluder fail to be installed correctly, or if power is removed, the occluder will return to its biased closed position, preventing free flow. The occluder may also be placed in an integrated unit such that the automatic safety occluder may attach to the tubing as a unit.

13. A system for selectively controlling flow through an infusion tube comprising:
-
a pump having a body and a pumping mechanism; a recess formed in the pump body for receiving an occluder of an infusion set; an electric solenoid disposed in communication with the recess; an infusion set having a tube for delivering a fluid and an occluder disposed thereon; and wherein the infusion set is mounted in the pump such that the tube engages the pumping mechanism and such that the occluder is positioned in the recess such that actuation of the solenoid actuates the occluder to selectively allow flow through the tube; wherein the occluder comprises; a body; a plunger; a passage through the body; a passage through the plunger; wherein the tube passes through the body passage and the plunger passage; and wherein the plunger moves between a first position wherein the body passage and the plunger passage are in alignment so as to allow flow through the tube and a second position wherein the tube is pinched closed by the body passage and the plunger passage; and wherein the solenoid is attached to the plunger and not to the body of the occluder such that actuation of the solenoid will not actuate the occluder if the occluder and solenoid are not constrained to a fixed position. - View Dependent Claims (14, 15)

16. A system for selectively controlling flow through a tube for delivering fluid to a patient, the system comprising:
-
a pump having a body, a pumping mechanism and a recess for receiving a tube; an electric solenoid disposed in communication with the pump body; a fluid delivery set mounted in the pump, the fluid delivery set having a fluid delivery tube which engages the pumping mechanism and an occluder disposed along the tube for selectively preventing flow through the tube; and wherein the solenoid is disposed in communication with the occluder such that actuation of the solenoid actuates the occluder to selectively allow flow through the tube; wherein the occluder comprises a body and a plunger movable within the body, and wherein the tubing extends through the plunger and the body such that the plunger allows fluid to flow through the tubing in the first position and pinches the tubing closed to prevent fluid flow through the tubing when in the second position; and wherein the solenoid is disposed in communication with the plunger and not to the body of the occluder such that actuation of the solenoid will not actuate the occluder if the occluder and solenoid are not constrained to a fixed position. - View Dependent Claims (17)
