APPLICATOR AND METHOD FOR DISPENSING A FLUID AND A PARTICULATE

摘要

An applicator and method for dispensing a stream of a particulate and a fluid from a cannula and a mixing tip. The mixing tip includes a housing having an inlet, an outlet, and a mixing channel extending therebetween. A fin is positioned within the housing and extends along at least a portion of the mixing channel. The fin spirals about the mixing channel from the inlet toward the outlet for mixing and distributing the particulate generally uniformly within the fluid. The stream is directed into the mixing channel of the mixing tip and spiraled along the fin within the mixing channel. The spiraling increases turbulence and mixes the stream into a mixed stream of particulate and fluid. The mixed stream is discharged from the mixing tip for being dispensed onto an anatomical site.

主权项

1. An applicator for dispensing a generally uniform density of a particulate and a fluid for use during a medical procedure, the device comprising;
a cannula, the cannula having a distal cannula end portion and a flow channel extending therethrough; a mixing tip, the mixing tip operatively connected to the distal cannula end portion, the mixing tip further comprising;
a housing having a proximal end portion and a distal end portion;an inlet positioned at the proximal end portion of the housing, the inlet fluidly connected to the flow channel for receiving a stratified particulate and fluid;an outlet positioned at the distal end portion of the housing;a mixing channel extending through the housing from the inlet to the outlet; anda first fin positioned within the housing and extending along at least a portion of the mixing channel, the first fin configured in a generally spiral shape about the mixing channel and positioned between the inlet and the outlet for mixing the particulate and the fluid and distributing the particulate generally uniformly within the fluid for discharge from the outlet.
