Abstract
Systems and methods for applying or dispensing surgical prep solution. The applicator system includes a spreader element and a container of surgical prep solution. The spreader element includes a body with an orifice covered by a pad. The orifice is in fluid communication with a passage through an elongated stem connected to the body. The container may be collapsible with only limited recovery. The spreader element may include a receptacle for receiving the container.
Claims33
An applicator system for surgical prep solution, the system comprising:
- a spreader element comprising:
- a body comprising an orifice;
- a pad attached to the body over the orifice;
- a stem comprising a distal end attached to the body and a passage extending between the distal end of the stem and a proximal end of the stem, wherein the passage is in fluid communication with the orifice at the distal end of the stem;
- a collapsible container comprising:
- surgical prep solution;
- a spout adapted to attach to the proximal end of the stem, wherein the surgical prep solution can be delivered to the passage for delivery to the pad;
- wherein the collapsible container comprises an original volume and a collapsed volume after dispensing of the surgical prep solution, and further wherein the collapsible container recovers about 50% or less of a difference between the original volume and the collapsed volume within 30 seconds of dispensing a majority of the surgical prep solution.

A method of applying surgical prep solution, the method comprising:
- providing a spreader element comprising a body comprising an orifice;
- a pad attached to the body over the orifice, a stem comprising a distal end attached to the body and a passage extending between the distal end of the stem and a proximal end of the stem, wherein the passage is in fluid communication with the orifice at the distal end of the stem;
- providing surgical prep solution in a collapsible container;
- attaching the collapsible container to the proximal end of the stem, wherein the surgical prep solution is in fluid communication with the passage of the stem;
- and
- dispensing the surgical prep solution into the passage by compressing the collapsible container, wherein the collapsible container comprises an original volume and a collapsed volume after dispensing of the surgical prep solution, and further wherein the collapsible container recovers about 50% or less of a difference between the original volume and the collapsed volume within 30 seconds of dispensing a majority of the surgical prep solution.

A method of manufacturing an applicator system for surgical prep solution, the method comprising:
- providing a spreader element comprising a body comprising an orifice;
- a pad attached to the body over the orifice;
- a stem comprising a distal end attached to the body and a passage extending between the distal end of the stem and a proximal end of the stem, wherein the passage is in fluid communication with the orifice at the distal end of the stem;
- providing a collapsible container comprising surgical prep solution and a spout adapted to attach to the stem of the spreader element, wherein the surgical prep solution can be delivered to the passage for delivery to the pad;
- wherein the collapsible container comprises an original volume and a collapsed volume after dispensing of the surgical prep solution, and further wherein the collapsible container spontaneously recovers about 50% or less of a difference between the original volume and the collapsed volume within 30 seconds of dispensing a majority of the surgical prep solution.
