Abstract

A universal reclining armrest system for use with an articulated examination chair. The system includes an armrest adapter having a universal aperture for receiving a post portion of an armrest assembly. The armrest adapter further includes a splined peg for coupling to a pivoting mechanism of an articulated chair. The pivoting mechanism enables the chair to move throughout an operable range of motion while maintaining a fixed rotational position of an attached armrest adapter. The armrest assembly further includes an adjustable joint to provide 360° of rotational adjustment to the armrest relative to the fixed position of the armrest adapter.

Claims

1. An interchangeable device system comprising:

an articulated chair having a backrest hingedly coupled to a seat, wherein the backrest and the seat are adjustable over an operable range of motion; and

a first device adapter that is coupleable with a first device and that is interchangeably coupled to a first portion of the backrest at a first desired orientation relative to a horizontal plane, the first desired orientation of the first device adapter being maintained throughout the operable range of motion of the articulated chair, the first device adapter being selectively removable from the first portion of the backrest, and being interchangeably coupleable with a second portion of the backrest, which is opposite to the first portion of the backrest, the second portion adapted to receive the first device adapter such that the first device adapter is at a second desired orientation relative to the horizontal plane, and such that the second desired orientation of the first device adapter is maintained throughout the operable range of motion of the articulated chair.

2. The system of claim 1, wherein the first device is an intravenous armrest having a planar surface for supporting an arm of a patient in an extended position.

3. The system of claim 1, further comprising a second device adapter that is coupleable with a second device and that is interchangeably coupled to the second portion of the chair at a third desired orientation relative to the horizontal plane, wherein the third desired orientation of the second device adapter is maintained throughout the operable range of motion of the articulated chair, the second device adapter being selectively removable from the second portion of the backrest and being interchangeably coupleable with the first portion of the backrest, the first portion adapted to receive the second device adapter, such that the second device adapter is at a fourth desired orientation relative to the horizontal plane, and such that the fourth desired orientation of the second device adapter is maintained throughout the operable range of motion of the articulated chair.

4. The system of claim 3, wherein the first and second devices assist in the treatment of at least one of the following:

i) an intravenous infusion;

ii) an administration of an anesthesia;

iii) dialysis;

iv) chemotherapy;

v) phlebotomy;

vi) platelet or plasma apheresis;

vii) a surgical procedure;

viii) a cosmetic procedure; and

ix) an elective procedure.

5. The system of claim 1, wherein the articulated chair comprises an examination chair.

6. The system of claim 1, wherein the first desired orientation is equal to the second desired orientation.

7. The system of claim 1, wherein the first portion of the backrest comprises a first side of the backrest, and the second portion of the backrest comprises a side of the backrest that is opposite the first side of the backrest.

19. The system of claim 1, wherein the interchangeable device system further comprises a retaining mechanism to selectively attach the first device adapter to and to selectively detach the first device adapter from a location selected from the first portion and the second portion of the backrest.

20. The system of claim 1, wherein the first device adapter is interchangeably coupleable with the second portion of the backrest at a plurality of different orientations.

8. An interchangeable device system comprising:

an articulated chair having a backrest hingedly coupled to a seat, wherein the backrest and the seat are adjustable over an operable range of motion, the backrest having a first side and a second side, the first side being positioned opposite the second side; and

a first device interchangeably coupled to the first side of the backrest at a first desired orientation relative to a horizontal plane, the first desired orientation of the first device being maintained throughout the operable range of motion of the articulated chair, the first device being selectively removable from the first side of the backrest and adapted to be coupleable with the second side of the backrest at a second desired orientation relative to the horizontal plane, such that the second desired orientation of the first device is maintained throughout the operable range of motion of the articulated chair.

9. The system of claim 8, wherein the first device is interchangeably coupleable with the second side of the backrest at a plurality of different orientations.

10. The system of claim 8, wherein the first, device is an intravenous armrest having a planar surface for supporting an arm of a patient in an extended position.

11. The system of claim 8, wherein the interchangeable device system further comprises a retaining mechanism to selectively attach the first device to and to selectively detach the first device from a location selected from the first side and the second side.

12. The system of claim 8, wherein the first device is configured to assist in the treatment of at least one of the following:

i) an intravenous infusion;

ii) an administration of an anesthesia;

iii) dialysis;

iv) chemotherapy;

v) phlebotomy;

vi) platelet or plasma apheresis;

vii) a surgical procedure;

viii) a cosmetic procedure; and

ix) an elective procedure.

13. The system of claim 8, wherein the second desired orientation is the same as the first desired orientation.

14. The system of claim 8, wherein a portion of the first device is a support surface.

15. An interchangeable device system comprising:

an articulated surface for supporting a patient having a first portion hingedly coupled to a second portion, wherein the first portion and the second portion are adjustable over an operable range of motion; and

a first device adapter that is coupled to a first device and that is interchangeably coupled to a first side of the first portion such that the first device adapter is at a first desired orientation relative to a horizontal plane and the first device is at a second desired orientation relative to the horizontal plane, the first desired orientation of the first device adapter and the second desired orientation of the first device being maintained throughout the operable range of motion of the articulated surface for supporting the patient, the first device adapter being selectively removable from the first side of the first portion and adapted to be interchangeably coupleable with a second side of the first portion, which is substantially opposite to the first side, such that the first device adapter is at a third desired orientation relative to the horizontal plane and the first device is at a fourth desired orientation relative to the horizontal plane and such that the third and fourth desired orientations of the first device adapter and the first device, respectively, are maintained throughout the operable range of motion of the surface for supporting a patient.

16. The system of claim 15, wherein the first device adapter is interchangeably coupleable with the second side of the first portion at a plurality of different orientations.

17. The system of claim 15, wherein the interchangeable device system further comprises a retaining mechanism to selectively attach the first device adapter to and to selectively detach the first device adapter from a location selected from the first side and the second side of the first portion.

18. The system of claim 15, wherein the first device is selectively releasable from the first device adapter, such that a second device that is structurally different from the first device is interchangeably coupleable with the first device adapter.
