Medical fluid delivery system with uniquely configured pump unit and fluid delivery set
First Claim
1. A medical fluid delivery system comprising:
- a peristaltic pump unit, anda fluid delivery set adapted to be operatively mounted on the pump unit, said fluid delivery set comprising a drip container having a longitudinal axis for holding fluid to be pumped by the pump unit, and a formation on the drip container having an external contour of unique configuration, said external contour being non-circular in a plane generally transverse to said longitudinal axis of the drip container,said pump unit comprising holding means having a socket for receiving and holding said drip container in an operative position on the pump unit,said socket having a uniquely configured non-circular internal contour adapted to mate with the uniquely configured external contour of said formation on the drip container when the drip container is received in the socket whereby a fluid delivery set without said uniquely configured formation cannot be mounted in said operative position on the pump unit.

Abstract
A medical fluid delivery system comprising a peristaltic pump unit and a fluid delivery set adapted to be operatively mounted on the pump unit. The fluid delivery set comprises a drip container for holding fluid to be pumped by the pump unit, and a formation on the drip container having an external contour of unique configuration. The pump unit comprising a holder having a socket therein for receiving and holding the drip container in an operative position on the pump unit. The socket has a uniquely configured internal contour adapted to mate with the uniquely configured external contour of the formation on the drip container whereby a fluid delivery set without the uniquely configured formation cannot be mounted in operative position on the pump unit.

17. A peristaltic pump unit for use in a medical fluid delivery system, said pump unit being adapted for use with a fluid delivery set comprising a drip container for holding fluid to be pumped by the pump unit, said drip container having a longitudinal axis and a formation on the container with a uniquely configured, non-circular external contour, said pump unit comprising
a housing, and means on the housing for holding said drip container in an operative position on the pump unit, said holding means on the housing comprising a socket having an internal side wall with a uniquely configured, non-circular internal contour adapted to mate with the uniquely configured external contour of said formation on the drip container whereby a drip container without said uniquely configured formation cannot be mounted in operative position on said pump unit, the internal side wall of the socket being generally polygonal in shape in a plane generally transverse to the longitudinal axis of the drip container.

21. A peristaltic pump unit for use in a medical fluid delivery system, said pump unit being adapted for use with a fluid delivery set comprising a drip container for holding fluid to be pumped by the pump unit, said drip container having a formation thereon with a uniquely configured, non-circular, generally triangular external contour, said pump unit comprising:
-
a housing, and means on the housing for holding said drip container in an operative position on the pump unit, said holding means on the housing comprising a socket having an internal side wall with a uniquely configured, non-circular generally triangular internal contour adapted to mate with the uniquely configured generally triangular external contour of said formation on the drip container whereby a drip container without said uniquely configured formation cannot be mounted in operative position on said pump unit.
