Abstract

A clamping system of universally interchangeable clamping components and accessories for use with standard healthcare equipment or patient healthcare procedures. The clamping system includes a support rod, a slip-coupling and a mounting bracket from which depends a short perpendicular post, which bracket may be permanently affixed to any piece of furniture. The slip-coupling is a tubular body defining a receiving bore for close passage of the perpendicular post at a first end, and a through bore passing at a right angle to the receiving bore at the opposite end. A set screw is removably threaded through the tubular body and attached to an oversized knob head for easy manual rotation to tighten and release the set screw. The support rod passes through the through bore and from which other slip-couplings or a secondary slip-coupling are mounted. The rod is vertically oriented relative to the appliance to provide support for horizontally mounted secondary slip-couplings from which accessories depend, such as a removable tray, an arm rest, an elbow rest, a handle bar and veterinary limb clamp. A slotted bar serves as a horizontal appendage to which a secondary slip-coupling is attached to hold an I.V. pole.

Claims

1. A clamping system comprising:

a mounting bracket having a plate and at least two posts depending from said plate;

a support rod; and

,

a slip-coupling having a tubular body having a central longitudinal axis and a uniform cross section defined in a plane transverse to the longitudinal axis, comprising

a first end portion defining a receiving bore along the central longitudinal axis, said receiving bore configured to closely receive one said post,

a second end portion defining a through bore oriented perpendicularly to the central longitudinal axis and configured to closely receive said support rod,

a first releasable lock means for locking said slip-coupling from rotation about said one post; and

,

a second releasable lock means for locking said slip-coupling from sliding along said support rod.

2. The clamping system according to claim 1, further comprising a leaf-spring disposed within said receiving bore.

3. The clamping system according to claim 1, further comprising a limb clamp accessory having means for securing the limb of an animal.

4. The clamping system according to claim 1, further comprising a tray accessory comprising a tray attached to an arm dimensioned and configured to closely pass into the receiving bore of the first end portion of said slip-coupling.

5. The clamping system according to claim 1, further comprising a tray accessory including

a tray attached to an arm removably and closely passing into said receiving bore of the first end portion of said slip-coupling, said arm defining a first pin hole,

said first end portion defining a second pin hole in registry with said first pin hole, and

a wrist pin removably inserted into both said first pin hole and said second pin hole.

6. The clamping system according to claim 5, wherein said wrist pin is attached to a tether having a ring dimensioned to closely pass over said support bar.

7. The clamping system according to claim 1, wherein said first releasable lock means of said slip-coupling is a first set screw threaded through said tubular body and oriented perpendicularly to said receiving bore and having a knob head for manual rotation of said first set screw.

8. The clamping system according to claim 1, wherein said support rod is L-shaped.

9. The clamping system according to claim 1, further comprising a bipartite clamp unit including a first part and a second part together defining a split, cylindrical passage, said first part having a hole in registry with said threaded bore for receiving a matingly threaded screw of said secondary slip-coupling, and a screw passing through said hole and secured to said threaded bore.

10. A clamping system comprising:

a mounting bracket having a plate and a post depending from said plate;

a support rod;

a slip-coupling having a tubular body having a central longitudinal axis and a uniform cross section defined in a plane transverse to the longitudinal axis, comprising

a first end portion defining a receiving bore along the central longitudinal axis, said receiving bore configured to closely receive said post,

a second end portion defining a through bore oriented perpendicularly to the central longitudinal axis and configured to closely receive said support rod,

a first releasable lock means for locking said slip-coupling from rotation about said post, and,

a second releasable lock means for locking said slip-coupling from sliding along said support rod;

a secondary slip-coupling including

a shank, having a central longitudinal axis and a uniform cross section defined in a plane transverse to the longitudinal axis, comprising

a primary end portion having a planar terminal surface defined by said uniform cross section and defining a threaded bore for receiving a matingly threaded screw,

a secondary end portion defining a through passage oriented perpendicularly to the central longitudinal axis and configured to closely receive said support rod; and

,

a third releasable lock means for locking said secondary slip-coupling from sliding along said support rod.

11. The clamping system according to claim 10, further comprising an arm rest accessory including

a prismatically L-shaped member having a mounting bracket dimensioned and configured to closely receive said primary end portion of said secondary slip-coupling and defining an aperture in registry with said threaded bore of said primary end portion, and

a screw passing through said aperture and matingly received by said threaded bore.

12. The clamping system according to claim 10, further comprising an elbow rest accessory including

a prismatically U-shaped member having an end wall defining an aperture in registry with said threaded bore of said primary end portion, and

a screw passing through said aperture and matingly received by said threaded bore.

13. The clamping system according to claim 10, further comprising a handle bar accessory being an elongated secondary slip-coupling including a handle grip covering said primary end portion, said handle grip being manufactured of a material having non-slip and cushioning characteristics.

14. The clamping system according to claim 10,

wherein further said second releasable lock means of said slip-coupling is a second set screw removably threaded through said tubular body and oriented perpendicularly to said through bore attached to a knob head for manual rotation of said second set screw,

wherein said third releasable lock means of said secondary slip-coupling is a third set screw removably threaded through said tubular body and oriented perpendicularly to said through passage attached to a knob head for manual rotation of said third set screw, and

further comprising a bar defining an elongated slot dimensioned to allow passage of both the second set screw and the third set screw and preventing passage of the knob heads,

whereby the second set screw and the third set screw may be passed through said slot of said bar at any one of an infinitely variable number of points along the slot, and by tightening said set screws, the bar secured between the knob heads and each respective tubular body or shank.

15. The clamping system according to claim 10, further including an I.V. pole configured to closely pass through both said through passage of said secondary slip-coupling and said through bore of said slip-coupling.

16. The clamping system according to claim 10, further comprising a bipartite clamp unit including a first part and a second part together defining a split, cylindrical passage, said first part having a hole in registry with said threaded bore for receiving a matingly threaded screw of said secondary slip-coupling, and a screw passing through said hole and secured to said threaded bore.

17. The clamping system according to claim 10, further comprising a tray accessory comprising a tray having a mounting bracket dimensioned and configured to closely receive said primary end portion of said secondary slip-coupling and defining an aperture in registry with said threaded bore of said primary end portion, and

a screw passing through said aperture and matingly received by said threaded bore.
