Abstract

Some patients have an catheter extending from an upper arm in order to administer intravenous pharmaceuticals. A clamping apparatus rigidly holds an end of the catheter during pharmaceutical administration thus allowing the procedure to be performed using only the patient'"'"'s free hand. The apparatus has a base from which a support member extends. A mechanism enables the support member to be positioned at a number of angles with respect to the base. A catheter clamp can be attached along the support member in a number of positions. This mechanism allows the position of the clamp to be varied in order to accommodate patients having arms of different size.

Claims

1. An apparatus for enabling a patient, with a tube extending from an arm, to administer a pharmaceutical through the tube, said apparatus comprising:

a base having a surface on which the patient rests the arm during use of the apparatus;

a support member extending from said base and having a rigid section with a longitudinal axis;

a clamp attached to said support member to receive and hold the tube; and

a mechanism attaching said support member to said base so that said support member can be located in a plurality of positions at each of which the longitudinal axis is at different angle in a plane that intersects the surface of said base.

2. The apparatus as recited in claim 1 wherein said mechanism comprises a plurality of apertures in said base for receiving said support member, wherein an angle at which said support member extends from said base can be varied by placing said support member in different ones of said plurality of apertures.

3. The apparatus as recited in claim 1 wherein said support member pivotally extends from said base;

and wherein said mechanism comprises a spring which biases said support member in one rotational direction, and a strut attached to said support member for engaging stops on said base.

4. The apparatus as recited in claim 1 wherein said mechanism comprises a spring loaded device for pivotally attaching said support member to said base and biasing said support member in one rotational direction;

and a strut attached to said support member for engaging stops on said base.

5. The apparatus as recited in claim 1 wherein said clamp includes a device that releasably attaches to said support member so that said clamp may be positioned at different locations on said support member.

6. An apparatus for enabling a patient, having a tube extending from an arm, to administer a pharmaceutical through the tube, said apparatus comprising:

a support member;

a clamp attached to said support member to receive the tube; and

a base on which the patient rests the arm during use of the apparatus and having a surface with a plurality of apertures for receiving said support member, each aperture having a longitudinal axis at a different angle with respect to the surface so that said support member can be rigidly positioned at a plurality of different angles with respect to the surface.

7. The apparatus as recited in claim 6 wherein said clamp includes a device that releasably attaches to said support member so that said clamp may be positioned at different locations on said support member.

8. An apparatus for enabling a patient, with a tube extending an arm, to administer a pharmaceutical through the tube, said apparatus comprising:

a base on which the patient rests the arm during use of the apparatus;

a support member attached to said base and rotatable with respect to said base;

a strut attached to said support member for engaging stops on said base to hold said support member in a given position against a bias provided by said spring; and

a clamp attached to said support member to receive the tube.

9. The apparatus as recited in claim 8 further comprising a spring which biases said support member in one rotational direction.

10. The apparatus as recited in claim 8 wherein said support member has a L-shape with a first leg to which said clamp is attached and a second leg attached to said base by a bracket;

and further comprising a torsion spring wrapped around the second leg and bias said support member in one rotational direction.

11. The apparatus as recited in claim 8 wherein said clamp includes a device that releasably attaches to said support member so that said clamp may be positioned at different locations on said support member.

12. The apparatus as recited in claim 8 wherein said support member has one end fixedly attached to said base, and a joint that permits another end of said support member to move away from the base 62.

13. The apparatus as recited in claim 8 wherein said support member has one end fixedly attached to said base, and a resilient joint that permits another end of said support member to move away from the base 62.
