Abstract

There is disclosed a system for cleaning and disinfecting allograft material. In an embodiment, the system includes a sterile bag and a motorized paddle blender. The sterile bag having an outer wall configured to withstand blending forces, at least one paddle contact section, and a free-floating mesh bag configured to retain the allograft material. The motorized paddle blender having at least one paddle configured to apply blending forces on the sterile bag on the at least one paddle contact area, a motorized portion to actuate the at least one paddle, and a door component configured to hold the sterile bag adjacent the at least one paddle. The at least one paddle and the allograft retaining section are configured to prevent the paddle from contacting the allograft material when the blending forces are applied on the sterile bag on the at least one paddle contact area.

First claim

What is claimed is:

1. A system for cleaning and disinfecting allograft material, the system comprising:
a sterile bag having an outer wall configured to withstand blending forces, at least one paddle contact section, and a free-floating mesh bag configured to retain the allograft material, an allograft retaining section separate from the at least one paddle contact section;
a motorized paddle blender having at least one paddle configured to apply blending forces on the sterile bag on the at least one paddle contact area, a motorized portion to actuate the at least one paddle, and a door component configured to hold the sterile bag adjacent the at least one paddle, wherein the at least one paddle and the allograft retaining section are configured to prevent the paddle from contacting the allograft material when the blending forces are applied on the sterile bag on the at least one paddle contact area.

2. A system in accordance with claim 1 , wherein the sterile bag is a paddle blender bag having modifications to provide the allograft retaining section separate from the at least one paddle contact section.

3. A system in accordance with claim 1 , wherein the motorized paddle blender includes two paddles separated by a given distance to apply blending forces on the sterile bag at two paddle contact sections, and the allograft retaining section having a width less than the given distance separating the two paddles so as to allow the allograft retaining section to retain the allograft material between the two paddle contact sections corresponding to the two paddles.

4. A system in accordance with claim 1 , further comprising a hollowed port system within the at least one paddle configured to provide temperature control.

5. A system in accordance with claim 1 , further comprising an ultrasonic water bath configured to submerge the sterile bag and the motorized paddle blender.

6. A system in accordance with claim 5 , wherein the ultrasonic water bath is configured to control temperature of the allograft material.

7. A system in accordance with claim 6 , wherein the ultrasonic water bath is configured to supplement mechanical washing of the allograft material with forces of fluid created by the at least one paddle.

8. A system in accordance with claim 1 , wherein the free-floating mesh bag configured to retain the allograft material further includes at least one magnet configured to locate the free-floating mesh bag with the allograft material apart from the reciprocating paddle sections.
