Manual mixer
First Claim
1. A manual mixer for mixing and agitating materials for use during surgery, the manual mixer comprising:
- a body portion having a sidewall portion defining an interior area;
a mixing assembly provided in the interior area of the body portion, the mixing assembly including a plunger portion and a resilient member, the plunger portion interfacing with the sidewall portion, and the plunger portion including a portion for engaging the resilient member, the resilient member including a first end portion, a second end portion, and a length extending between the first end portion and the second end portion thereof, the resilient member having a non-uniform cross section along the length, the plunger portion being adapted to move upwardly and downwardly within the interior area;
a cap portion attached to the body portion, the cap portion enclosing the interior area of the body portion, and the cap portion including an aperture that is at least partially threaded; and
a stem portion extending through the partially-threaded aperture in the cap portion, the stem portion being at least partially threaded, wherein threads of the partially-threaded stem portion and threads of the partially-threaded aperture engage one another, and wherein rotation of the stem portion rotates the resilient member, and moves the plunger portion upwardly or downwardly within the interior area, the rotational movement of the resilient member, and upward and downward movement of the plunger portion serving to mix and agitate the materials provided in the interior area, the resilient member being expanded when the plunger portion is moved upwardly, and the resilient member being compressed when the plunger portion is moved downwardly.

Abstract
A manual mixer serves to facilitate mixing and agitating materials for use during surgery. For example, the manual mixer includes a body portion defining an interior area, a mixing assembly provided in the interior area of the body portion, a crank assembly for actuating the mixing assembly, and a valve assembly. The mixing assembly serves to mix and agitate the materials provided in the interior through rotation of a plunger portion and a spring attached thereto, and through upwards and downwards movement of the plunger portion in the interior area. Rotation of the crank assembly serves to rotate the plunger portion and the spring attached thereto, and effectuate upwards and downwards movement of the plunger portion. The valve assembly can be opened to facilitate dispensing of the materials from the interior area.

9. A method of mixing and agitating materials using a manual mixer, the method comprising:
-
providing the manual mixer having a body portion, a mixing assembly, and a stem portion, the body portion defining an interior area, the mixing assembly being provided in the interior area, and the stem portion being interconnected with a portion of the mixing assembly; removing the mixing assembly from the interior area; providing the materials to be mixed and agitated in the interior area; replacing the mixing assembly in the interior area; and rotating the stem portion to rotate a resilient member of the mixing assembly, and move a plunger portion of the mixing assembly upwardly or downwardly within the interior area, the rotation of the resilient member, and upwards and/or downwards movement of the plunger portion serving to mix and agitate the materials provided in the interior area, the plunger portion being moveable between a first position and a second position, the first position being a maximum upward position of the plunger portion, and the second position being a maximum downward position of the plunger portion, the resilient member being expanded when the plunger portion is moved upwardly within the interior area toward the first position, and the resilient member being compressed when the plunger portion is moved downwardly within the interior area toward the second position. - View Dependent Claims (10, 11, 12, 13, 14, 15)
