Abstract

In one embodiment, a door is used to provide uniform pressure to insert tubing into slots of a pump having walls that are narrower than the outer diameter of the tubing. In another embodiment, connectors are attached to receptacles on the pump, where the connectors insert and/or hold the tubing in slots of the pump. The connectors push the tubing into the slots while closing thereby covering the slots, which helps assure that the tubing is properly inserted into the slots. Optionally, the tubing may be partially affixed to the connectors so that detaching the connectors from the pump receptacles may remove the tubing from the slots. In one embodiment, as long as the connectors are connected to the pump receptacles properly, the tubing is properly inserted and/or retained in the slots.

Claims

1. A device, comprising:

a pump that transports fluid in a tubing of a particular outside diameter in a particular direction;

a slot in the pump, into which the tubing is inserted;

a door for inserting the tubing into the slot, the door being hingedly connected to the pump, wherein the door, when closed, covers the slot with two sides of the door extending beyond either side of the slot;

two panels, one at each side of the door, each panel having a notch for guiding the tubing;

the notch having an opening that faces away from an underside of the door and faces towards the slot, so that during noiinal operation the tubing can be located in the slot without being located in the notch, the tubing can remain in the slot without contacting the notch as the door swings closed, and only after the door is at an angle that is closer to being closed than to being fully open, the notch contacts the tubing and pushes the tubing into the slot as the door is further closed;

a bar connecting the two panels at the sides of the door for providing pressure across a length of the tubing for pushing the tubing into the slot as the door is closed.

2. The device of claim 1, further comprising a lock for locking and releasing the door.

3. The device of claim 1, wherein the slot is slightly narrower than the outside diameter of the tubing.

4. The device of claim 1, wherein the notches formed by the panels are narrower than the outside diameter of the tubing for retaining the tubing, and as a result opening the door retracts the tubing from the slot.

5. The device of claim 1, wherein the slot is within a sensor, wherein the sensor measures properties of the fluid in the tubing in the slot.

6. The device of claim 5, wherein the sensor is a bubble detector for detecting bubbles in the tubing.

7. The device of claim 5, wherein the sensor is a pressure sensor for measuring pressure of the fluid in the tubing.

8. The device of claim 5, wherein as a result of the bar pushing the tubing into the slot, the tubing is aligned with the sensor.

9. The device of claim 1, wherein the bar includes a concave surface facing the slot, the concave surface being in contact with an arc of the tubing across a length of the tubing.

23. The device of claim 1, the bar being straight.

25. The device of claim 1, further comprising a hinge via which the door is hingedly connected to the pump, the hinge not being configured to be detachable from the door, and the hinge not being configured to be detachable from the pump.

10. A device, comprising:

a pump that transports fluid in a tubing of a particular outside diameter in a particular direction, the pump having a receptacle for engaging a connector;

a door having an underside facing a peristaltic pump mechanism and covering the peristaltic pump mechanism, the receptacle being located to a side of the door that is not covered by the door, the receptacle is not covered by the door;

a slot in the pump receptacle;

the connector that engages the receptacle includes guiding and supporting structures for inserting the tubing into the slot and retaining the tubing in place, the connector being partially attached to the tubing;

wherein the connector is detachable from the receptacle, wherein detaching the connector from the receptacle results in retracting the tubing from the slot.

11. The device of claim 10, wherein the connector includes a tab that holds the connector to the receptacle and when depressed releases the connector from the receptacle.

12. The device of claim 10, wherein the guiding and supporting structures include at least two guiding members for guiding the tubing and a supporting edge with ends connected to the notches, each of at least two of the at least two guiding member forming a notch, the supporting edge having a concave surface facing the receptacle for providing pressure across a length of the tubing for pushing the tubing into the slot.

13. The device of claim 12, wherein the supporting edge is in contact with an arc of the tubing between 60 degrees and 180 degrees, the tubing having a length, the arc of the tubing being an arc that is perpendicular to the length.

14. The device of claim 12, wherein the two guiding members have partially circular grooves facing the receptacle.

15. The device of claim 12, wherein the two guiding members have channels for the tubing to go through.

16. The device of claim 12, wherein the connector being partially attached to the tubing including attachment of the tubing to the ends of the supporting edge but not along the supporting edge.

17. The device of claim 12, wherein the connector being partially attached to the tubing including attachment of the tubing to the at least two guiding members while the tubing is not attached to the supporting edge.

18. The device of claim 10, further comprising a conductor that completes a circuit which provides an indication that the tubing retained by the connector is fully and properly inserted into the slot.

19. The device of claim 10, wherein the connector being a first connector and the receptacle being a first receptacle, the device includes a second connector that engages with a second receptacle, wherein the first connector and the second connector are in different shape so that one of the first connector and the second connector is not able to engage the other'"'"'s receptacle.

20. The device of claim 10, wherein the slot is in at least a sensor for measuring properties of fluid in the tubing.

21. A method comprising:

partially attaching a tubing to a connector, the connector including at least two guiding members connected via a supporting edge for providing pressure across a length of the tubing;

inserting the connector in a receptacle on a pump, the connector being detachable from the receptacle, wherein inserting the connector in the receptacle connects to the connector to the pump, wherein a slot is located within the receptacle, the slot being located in only a portion of the receptacle, wherein the tubing is inserted into the slot as a result of the connector being inserted in the receptacle; and

wherein the tubing is retained in place, by the connector as a result of being partially attached to the connector, wherein the pump, when in operation, transports fluid in the tubing in a particular direction, wherein detaching the connector from the receptacle results in retracting the tubing from the slot and results in detaching the connector from the pump.

22. A device comprising:
