Abstract
Abstract A pressure-applying device for use in an infusion set for feeding blood, saline solution or other fluids from a compressible bag to a catheter or needle for administration to a patient. The device comprises at least a pair of highly resilient, arcuate shaped metallic plates pivoted along their adjacent edges and drawn together along their free edges by buckles or clasps. When pivoted into facing relation the adjacent convex surfaces of the plates act to squeeze fluid from the compressible bag when positioned therebetween. Use of the device obviates the necessity to elevate the infusion bag during use, since infusion is effected by positive pressure rather than by gravity alone.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
198 words
An assembly for exerting pressure upon a compressible fluid container, comprising: a. a pair of curved resilient plates having respective inner and outer planar edges extending transversely of the curvature thereof; b. hinge means for hingedly mounting said inner edges of the plates to one another in substantial parallelism for pivotal movement of the plates into facing relation with the convex surfaces of the plates facing one another; c. clasp means mounted along said outer edges of the plates for securing said edges to one another and thereby holding the plates in close proximity to one another with the convex surfaces thereof adapted to apply pressure to a compressible fluid container positioned between said plates; d. restraining means for limiting movement of the compressible fluid container transversely of said first and second plate edges to facilitate compression of the container and dispensing of the fluid theRefrom by said assembly; e. said restraining means comprises a hollow sleeve secured to said sheath in the region of said hinge and along the concave side of said plates for receiving a compressible fluid bag to prevent movement of said bag when said plate halves are being moved to the operating position.
Claim 2
Dependent Claim

An assembly for exerting pressure upon a compressible fluid container, comprising: a. a pair of curved resilient plates having respective inner and outer planar edges extending transversely of the curvature thereof; b. hinge means for hingedly mounting said inner edges of the plates to one another in substantial parallelism for pivotal movement of the plates into facing relation with the convex surfaces of the plates facing one another; c. clasp means mounted along said outer edges of the plates for securing said edges to one another and thereby holding the plates in close proximity to one another with the convex surfaces thereof adapted to apply pressure to a compressible fluid container positioned between said plates; d. restraining means for limiting movement of the compressible fluid container transversely of said first and second plate edges to facilitate compression of the container and dispensing of the fluid theRefrom by said assembly; e. said restraining means comprises a hollow sleeve secured to said sheath in the region of said hinge and along the concave side of said plates for receiving a compressible fluid bag to prevent movement of said bag when said plate halves are being moved to the operating position.
Claim 3
Dependent Claim
66 words
The assembly of claim 1, wherein said restraining means further comprises a plurality of hollow sleeves of different diameters secured to said sheath in the region of said hinge and along the concave side of said plates for receiving compressible fluid bags of varying sizes, each of said sleeves preventing movement of the bag received therein as said plate halves are moved to the operating position.
