Pinch clip occluder for infusion sets

An apparatus for preventing free flow in a tube of a delivery set when used with a pump, the apparatus comprising:

• a pump housing means for holding a tube of the delivery set, the pump housing means having at least one channel disposed therein for receiving the tube, and a cover means for selectively holding the tube within the at least one channel, the cover means having an open position wherein the tube can be removed from the at least channel, and a closed position, wherein the tube is held within the at least one channel;
• occluder means for selectively preventing flow through the tube, the occluder means comprising:
• an occluder housing having an open first end, an open second end and a passage extending from the open first end to the open second end for holding a tube of an infusion set;
• and
• plunger means disposed generally transverse to the passage of the occluder housing for selectively occluding flow through the tube, the plunger means comprising a plunger passage movable between a first position wherein the plunger passage is not in alignment with the passage through the occluder housing so as to occlude flow through the tube, and a second position wherein the plunger passage is in alignment with the passage through the occluder housing so as to allow flow through the tube;
• and
• wherein the cover means is disposed so that when the cover means is moved into the closed position, the cover means contacts and moves the plunger means from the first position, wherein the plunger passage is not in alignment with the passage through the occluder housing, to the second position, wherein the plunger passage is in alignment with the passage through the occluder housing.

Apparatus for selectively controlling flow through one or more tubes of an infusion delivery set, the apparatus comprising:

• a pump housing having:
• at least one channel disposed therein for receiving a tube of the delivery set,
• a cover means for holding the tube of the delivery set within the housing, the cover means having an open position wherein the delivery set can be removed from the at least one channel, and a closed position, wherein the delivery set cannot be removed from the at least one channel, and
• a void formed therein for receiving an occluder means;
• an occluder means nestible within the pump housing, the occluder means comprising:
• an occluder housing having an open first end and an open second end and a passage therethrough extending from the open first end to the open second end for receiving the tube of the delivery set, the occluder housing further comprising a knob disposed so as to extend downward from the housing for disposition in the void in the pump housing;
• flow restriction means disposed at least partially within the housing and moveable between a first position in which the flow restriction means occludes flow through the tube of the delivery set and a second position in which the flow restriction means does not occlude flow through the tube;
• and
• biasing means disposed adjacent the housing and the flow restriction means for biasing the flow restricting means into the first position;
• and
• wherein the cover means is disposed to contact and move the flow restriction means into the second position when the cover means is moved into the closed position.
