Abstract

An apparatus for intravenous feeding comprising a drum that is mounted for rolling movement along a base. A constant tension spring has one end thereof fixed to the drum and one end thereof fixed to the base. A collapsible container is positioned such that the drum under the action of the spring tends to collapse the container uniformly and thereby dispense of the contents of the container out of the container.

Claims

1. An apparatus for intravenous feeding comprising a base, means on the base for defining a track, a drum, means on the base for guiding the drum along the track for relative rolling movement with respect to the base, a constant tension spring wound about the periphery of said drum and having one end thereof fixed to the drum and the other end thereof fixed to said base adjacent one end thereof, whereby a collapsible fluid container positioned on the spring when said spring is in an unwound condition can be progressively compressed by the constant tension spring as the spring moves the drum on said base

2. The combination set forth in claim 1 including a handle attached to said drum for moving said drum against the action of said spring.

3. The combination set forth in claim 1 including low-friction contact surfaces on said drum engaging said base.

4. The combination set forth in claim 1 wherein said means for guiding said drum comprises a member on said base adjacent each end of said drum and extending longitudinally on said base and parallel to the direction of movement of said drum.

5. The combination set forth in claim 1 including stop means for limiting the movement of said drum toward said one end of said base.

6. The combination set forth in claim 5 including a handle connected to said drum.

7. The combination set forth in claim 6 including means on the other end of said base for engaging said handle and holding said drum in a retracted position.

8. The combination set forth in claim 5 wherein said stop means is adjustable longitudinally on said base.

9. The combination set forth in claim 4 including stop means on said guiding means for limiting the movement of said drum toward said one end of said base.

10. The combination set forth in claim 4 wherein said guiding means comprises guide rails spaced from said base and grooved portions on said drum engaging said rails.

11. The combination set forth in claim 1 including a stop on said base engageable by the end of a fluid container.
