Abstract

An apparatus for mounting and securing medical/surgical devices may be attached to a litter (40), The medical/surgical devices may include. for example, IV holders (186), aspirators (144). cardiac monitors (148) , defibrillators (150) , infusion pumps 152 (152), ventilators (146) and other devices. The apparatus frame assembly (10) includes rails (12), (14), (16), (18), (20), (46), (48), (50), (52) having cross-sections of standard surgical rails, for attachment of slidable rail clamps (84), (104). Medical device mounts (108), (110), (112) are attached to the slidable rail clamps. The medical device mounts have height and/or rotational adjustment to improve patient access and view. The apparatus may be mounted longitudinally anywhere along the litter to maximize access to the patient.

First claim

What is claimed is:

1. An apparatus for mounting medical devices, the apparatus including a frame assembly, comprising:
a pair of parallel rails fixed to at least two transverse rails extending between the pair of parallel rails;
a pair of arm assemblies pivotally attached to opposing first and second ends of the pair of parallel rails;
each arm assembly including a pair of parallel arms with each arm including a clamp at a distal end for engaging a pole of a litter having a pair of parallel poles, each arm assembly including two transverse rails extending between the pair of parallel arms;
each arm depending downwardly and normal to a respective one of the pair of parallel rails in an open position of the frame assembly and extending parallel to the respective one of the pair of parallel rails in a folded position of the frame assembly;
a pair of retractable spring plungers inserted through respective openings in the first ends of the pair of parallel rails and through respective openings in proximal ends of the pair of parallel arms to lock the pair of parallel arms of the arm assembly at the first end of the parallel rails normal to the first ends of the parallel rails; and
a tensioner assembly including a threaded rod with one end of the tensioner assembly pivotally attached to a lower one of the two transverse rails of the arm assembly at the second end of the pair of parallel rails and another end of the tensioner assembly disposed in a slotted receiver fixed to one of the at least two transverse rails extending between the pair of parallel rails.

2. The apparatus of claim 1 , wherein each clamp has a concave surface for receiving a pole of the litter.

3. The apparatus of claim 2 , further comprising the litter having the pair of parallel poles wherein each clamp engages one of the parallel poles.

4. The apparatus of claim 2 , wherein the parallel rails and transverse rails have a cross-section of North American standard surgical rails.

5. The apparatus of claim 2 , wherein the parallel rails and transverse rails have a cross-section of European standard surgical rails.

6. The apparatus of claim 2 , further comprising a swing stop pin fixed to each parallel rail to limit rotation of the arm assembly at the second end of the parallel rails to a position in a range of five degrees to twenty degrees past a position that is perpendicular to the parallel rails.

7. The apparatus of claim 1 , further comprising a rail clamp including a channel shaped to engage and slide along the parallel rails and the transverse rails.

8. The apparatus of claim 7 , wherein the rail clamp includes a rail body having an internally threaded opening that engages an externally threaded fastener, the externally threaded fastener including a contact disc at one end that presses against one of the parallel or the transverse rails to secure the rail clamp from sliding along the one of the rails.

9. The apparatus of claim 8 , wherein the rail clamp includes a stud fixed to the rail body for attachment of medical devices.

10. The apparatus of claim 9 , further comprising a medical device rotation assembly rotatably fixed to the stud of the rail clamp.

11. The apparatus of claim 10 , wherein the rotation assembly rotates 360 degrees on the stud.

12. The apparatus of claim 10 , wherein the rotation assembly is constrained from vertical translation with respect to the stud.

13. The apparatus of claim 12 , wherein the rotation assembly includes a boss and a clamp pivotally connected by a dowel, a first pivot pin with a threaded opening disposed in the boss, a second pivot pin with an unthreaded opening disposed in the clamp and a threaded rod that engages the threaded opening in the first pivot pin and extends through the unthreaded opening in the second pivot pin to an outside of the clamp.

14. The apparatus of claim 13 , wherein the vertical translation is constrained by lower inner diameter portions of the boss and the clamp engaging a lower portion of the stud which has a diameter that is smaller than a diameter of an adjacent portion of the stud.

15. The apparatus of claim 14 , wherein the boss includes a top surface, the apparatus further comprising a medical device mount fixed to the top surface.

16. The apparatus of claim 15 , wherein the medical device mount is one of an infusion pump mount, a defibrillator/cardiac monitor mount and an aspirator/ventilator mount.

17. The apparatus of claim 8 , further comprising an IV pole assembly fixed to the rail clamp, the IV pole assembly including a lower pole fixed to the rail clamp, an externally threaded compression bushing fixed to the lower pole, an internally threaded compression sleeve that engages the externally threaded compression bushing, an upper pole slidable and rotatable in the lower pole and an IV upper weldment at a top of the upper pole.

18. The apparatus of claim 1 , further comprising a tray assembly disposed on the second ends of the pair of parallel rails.

19. The apparatus of claim 16 , wherein the aspirator/ventilator mount incudes an angle mount weldment fixed to the top surface of the boss, a T-mount fitting fixed to the angle mount weldment, a threaded bolt extending through a threaded opening in the T-mount fitting, and a disc fixed to one end of the threaded bolt for tightening against an aspirator or ventilator.

20. The apparatus of claim 16 , wherein the defibrillator/cardia.c monitor mount includes a platform assembly fixed to the top surface of the boss, two hold downs fixed to the platform assembly, a pair of threaded platform pins that engage threaded openings in the platform assembly and a knob fixed to each of the pair of threaded platform pins.

21. The apparatus of claim 20 , further comprising a defibrillator/cardiac monitor having a bottom surface wherein each hold down of the platform assembly includes an overhang that mates with a gap above a ledge in the bottom surface of the defibrillator/cardiac monitor, and the platform pins are received in holes in the bottom surface adjacent to the ledges and further wherein the platforms pins are vertically translatable into the holes in the bottom surface by turning the knobs to thereby securely fasten the hold downs to the bottom surface of the defibrillator/cardia monitor.

22. The apparatus of claim 16 , wherein the infusion pump mount includes a pump pole with a base fixed with fasteners to the top surface of the boss and a pump yoke weldment fixed to a top surface of the pump pole.
