Abstract

An intravenous (IV) pole system for supporting medical equipment having a base with legs, a mast engaged to the base, and a lifting mechanism including a gas spring engaged to the base and the mast. Each of the legs includes at least one wheel. The lifting mechanism is constructed to position the legs in an extended configuration and a retracted configuration. The lifting mechanism is further constructed to raise the legs and wheels relative to the base and relative to a surface. The lifting mechanism is configured to position the wheels proximate to the mast in the retracted configuration.

Claims (39)

1. An IV pole system for supporting medical equipment comprising:

a base having a plurality of legs, each of said plurality of legs comprising at least one wheel;

a mast engaged to said base said mast comprising a length, a top, and a bottom; and

a lifting mechanism comprising a gas spring engaged to said base and to said mast,

said lifting mechanism being constructed and arranged to position said plurality of legs in an extended configuration and in a retracted configuration, at least a portion of said wheels being disposed lower than said bottom of said mast when said plurality of legs are in the extended configuration and said wheels being radially separated from said mast in said extended configuration, said lifting mechanism being further constructed and arranged to elevate said base and to draw at least a portion of said plurality of legs inwardly proximate to said mast in said retracted configuration and to position said wheels radially proximate to said mast and to said bottom and to elevate said wheels above a surface in said retracted configuration,

wherein when the plurality of legs are in the extended configuration, the wheel of each of the plurality of legs contacts the surface and the bottom of the mast does not contact the surface, and wherein when the plurality of legs are in the retracted configuration, the bottom of the mast contacts the surface.

2. The IV pole system of claim 1 said gas spring comprising:

two ends and a cylinder having a pin aperture, said gas spring further comprising a plunger, said plunger and said cylinder being movably engaged to each other, said gas spring being constructed and arranged to separate said two ends and to alter said length of said mast; and

said cylinder comprising a compressible fluid, said cylinder being constructed and arranged to exert a pneumatic force on said plunger to separate said two ends, said cylinder being further constructed and arranged to exert a pneumatic force on said plunger to elevate said base and to position said at least one leg into said retracted configuration.

3. The IV pole system of claim 2 wherein said at least one leg is pivotably engaged to said mast.

4. The IV pole system of claim 3 further comprising;

a brace, said brace being pivotally engaged to said base and to said at least one leg,

said pivotal engagement to said base being elevated relative to said pivotal engagement to said at least one leg when said at least one leg is in said retracted configuration.

5. The IV pole system of claim 4 wherein said cylinder is proximal to the base.

6. The IV pole system of claim 2 in which said gas spring is positioned within a hollow portion of said mast.

7. The IV pole system of claim 4 further comprising:

a gas release pin, the gas release pin being constructed and arranged to be inserted into and separated from said pin aperture, said gas release pin being constructed and arranged to actuate said gas spring.

8. The IV pole system of claim 7 further comprising:

a pedal having a pedal lever, said pedal lever being engaged to said gas release pin, said pedal lever being constructed and arranged to insert and separate said gas release pin relative to said pin aperture.

9. The IV pole system of claim 8 further comprising:

at least one wing extending substantially parallel to the mast, said at least one wing being engaged to said mast.

10. The IV pole system of claim 8 further comprising:

a halo, the halo comprising a outer frame having at least one hook projecting away from the frame, the frame being engaged to the mast proximate to said top.

11. The IV pole system of claim 8 further comprising a pole mount,

the pole mount comprising a horizontally sliding bar engaged to both a vertically extending support bar and at least one engagement member,

the vertically extending support bar comprising an elevating mechanism and one or more gripping members,

the gripping members being constructed and arranged for engagement to the mast,

the elevating mechanism being constructed and arranged to adjust a vertical position of said mast from a first position to a second position, where the second position is higher than the first position,

the horizontally sliding bar being constructed and arranged to adjust a horizontal separation distance between the at least one engagement member and the vertically extending support bar.

12. The IV pole system of claim 11 , the at least one engagement member being constructed and arranged to engage a hospital bed.

13. The IV pole system of claim 11 , further comprising a support bar engaged to the elevating member, the elevating member being constructed and arranged to lift said bar.

14. The IV pole system of claim 11 , further comprising a biasing mechanism engaged to the horizontally sliding bar, the biasing mechanism exerting a force on the horizontally sliding bar altering a separation distance between the at least one engagement member and the vertically extending support bar.

15. The IV pole system of claim 14 , the horizontally sliding bar further comprising an inner portion and an outer portion wherein the inner portion is in a telescoping relationship to the outer portion.

16. The IV pole system of claim 15 , wherein the horizontally sliding bar is pivotably engaged to the at least one engagement member.

17. The IV pole system of claim 11 in which the second position is higher than the first position by no more than one inch.

18. An IV pole system for supporting medical equipment comprising:

a base having a plurality of legs each of said plurality of legs comprising at least one wheel;

a mast engaged to said base, said mast comprising a length, a top, and a bottom; and

a gas spring lifting mechanism being constructed and arranged to elevate said base relative to said mast, said lifting mechanism being further constructed and arranged to position said plurality of legs in an extended configuration and in a retracted configuration, at least a portion of said wheels being disposed lower than said bottom of said mast when said legs are in the extended configuration and said wheels being radially separated from said mast in said extended configuration, said lifting mechanism being further constructed and arranged to elevate at least a portion of said legs proximate to said mast in said retracted configuration and to position said wheels radially proximate to said mast and to said bottom, and to elevate said wheels above a surface, in said retracted configuration.
