Abstract

A medical tubing and slide clamp set is disclosed for use with a medical infusion pump designed for operation with a preselected medical tubing set having predetermined size and functional characteristics. The medical tubing and slide clamp includes a preselected medical tubing set having predetermined size and function characteristics. An opaque slide clamp is provided with a grasping end and a longitudinal clamp plate extending from the grasping end. The longitudinal clamp plate defines a clamp slot with a wide open portion sized for receiving the preselected medical tubing without closing the tubing, a narrow open portion sized for closing the tubing and a transition portion interconnecting the narrow and wide portions. A plurality of orifices are formed along the longitudinal clamp plate at predetermined locations arranged according to the size and functional characteristics of the medical tubing set. A receptacle formed in a medical pump includes a plurality of light sources and sensors mounted at predetermined positions for sensing the orifices or the absence of orifices to determine whether the size and functional characteristics of the tubing set will are proper for operation in the medical pump.

Claims

1. A medical tubing and slide clamp set for use with a medical infusion pump designed for operation with a preselected medical tubing set having predetermined size and function characteristics, said set comprising:

(a) a preselected medical tubing set having predetermined size and functional characteristics;

(b) an opaque slide clamp comprising a grasping end, a longitudinal clamp plate extending from said grasping end, said longitudinal clamp plate defining a clamp slot with a wide open portion sized for receiving said preselected medical tubing without closing said preselected medical tubing and a transition portion interconnecting said narrow and wide portions of said clamp slot; and

(c) a plurality of light transmitting orifices formed at predetermined locations along said longitudinal clamp plate, sized and shaped to avoid passage of said medical tubing set therethrough and to permit transmission of light therethrough at said predetermined locations, said predetermined locations of said light transmitting orifices arranged on said clamp plate to indicate, by light transmission therethrough, said size and functional characteristics of said medical tubing set.

2. A medical tubing and slide clamp set of claim 1 wherein said plurality of orifices comprise two orifices formed at two predetermined locations selected from at least three predetermined locations on said opaque slide clamp.

3. A medical tubing and slide clamp set of claim 1 wherein said plurality of orifices comprise two orifices formed at two predetermined locations selected from at least four predetermined locations on said opaque slide clamp.

4. As in claim 1 wherein said plurality of orifices comprise three orifices formed at three predetermined locations selected from at least three predetermined locations on said opaque slide clamp.

5. As in claim 1 wherein said plurality of orifices comprise of three orifices formed at three predetermined locations selected from at least four predetermined locations on said opaque slide clamp.

6. As in claim 1 wherein said plurality of orifices comprise four orifices formed at predetermined locations selected from at least four predetermined locations on said opaque slide clamp.
