A support clamp 30 designed for attachment to a support 1 is extended from the distal end 25 of the housing 20. A C-shaped clamping member 40 is extended from the proximal end 24 of the housing 20. The C-shaped clamping member 40 has a pair of arms 41,42 each having a terminal end 43,44. The arms 41,42 of the clamping member 40 are spaced apart to define a clamping space therebetween for holding an object 2. A vibrating device 50 is provided within the hollow interior of the housing 20 and is designed for vibrating the housing 20.

In closer detail, the housing 20 has inner and outer surfaces 21,22 with the inner surface 21 defining the hollow interior of the housing 20. The housing 20 is preferably cylindrical in shape and has opposite proximal and distal ends 24,25.

Extending from the distal end 25 of the housing 20 is the support clamp 30. The support clamp 30 is designed for attachment to a support 1, such as a vertical elongate pole like a intravenous bag hanger. As shown in FIG. 2, the support clamp 30 has a base 31 and a clamping flange 32 with the base 31 positioned adjacent to the distal end 25 of the housing 20. The clamping flange 32 is spaced apart from the base 31 define a space between them for receiving a support 1 within the space. Preferably, the clamping flange 32 has a threaded clamping rod 33 extending through it for helping hold a support object I disposed within the space to the support clamp 30.

With reference to FIG. 2, the C-shaped clamping member 40 extends from the proximal end 24 of the housing 20. The clamping member 40 is designed for holding an object 2, such as a dialyzer, to the housing 20. The clamping member 40 has a pair of opposing arms 41,42 each terminating at a terminal end 43,44. The arms 41,42 of the clamping member 40 are spaced apart to define a clamping space therebetween for receiving an object 2, such as a dialyzer, therein. Each of the arms 41,42 has a threaded clamping rod 45,46 extending therethrough for holding the object 2 disposed within the clamping space to the clamping member 40. Preferably, each of the clamping rods 45,46 is positioned towards the terminal end 43,44 of its respective the arm 41,42. Ideally, the clamping rods 45,46 comprise quick-release pins.

As illustrated in FIG. 3, the vibrating device 50 is provided within the hollow interior of the housing 20. The vibrating device 50 is designed for vibrating the housing 20 so that an object held by the clamping member 50 is agitated. The vibrating device includes a motor 51 with a rotating shaft 52 disposed within the hollow interior of the housing 20. The motor 51 rotates the rotating shaft 52 when powered. Preferably, the motor 51 is mounted to the housing 20 to help hold the motor in place when rotating. The vibrating device 50 also includes an eccentric member 53 coupled to the rotating shaft 52 for vibrating the housing 20 when rotated. The rotating shaft 52 provides the eccentric motion of the eccentric member 53 when rotated.

Preferably, the vibrating device also includes a switch 54 electrically coupled to the motor 51 for permitting selective powering of the motor 51. The switch also preferably has an actuator 55 provided on the outer surface 22 of the housing 20 for permitting selective operation of the switch 54. A power source 56 is electrically coupled by an electric wire cord to the motor 51 to provide power to the motor 51.

In use, the agitator device is designed for vibrating a hemodialysis system having a dialyzer for providing dialysis to a patient. The agitator device 10 is designed for positioning between a support 1, such as the support pole of an intravenous bag holder, and an object 2, such as a dialyzer device. The device 10 is held to the support 1 by the support clamp 30 and its other end is attached to the dialyzer 2 with the clamping member 40. When the motor 51 is powered, the eccentric member 53 is rotated in an eccentric motion by and about the rotating shaft 52. This causes the housing 20 to vibrate thereby vibrating the object 2 held by the clamping member 40.

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
