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.
Claims18
An applicator system for surgical prep solution, the system comprising:
- a collapsible container comprising:
- surgical prep solution;
- and
- a spout;
- 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 proximal end of the stem is adapted to attach to the spout of the collapsible container, wherein the passage is in fluid communication with the orifice at the distal end of the stem and the collapsible container when the proximal end of the stem is attached to the spout;
- wherein the passage comprises a ratio of length of the passage between the distal and proximal ends to a minimum cross-sectional dimension of the passage of about 20:1 or more whereby flow of the surgical prep solution to the pad is restricted.
An applicator system for surgical prep solution, the stem comprising:
- a collapsible container comprising:
- surgical prep solution;
- and
- a spout;
- 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 comprising a flow restrictor, the stem extending between the distal end of the stem and a proximal end of the stem wherein the proximal end of the stem is adapted to attach to the spout of the collapsible container, and wherein the passage is in fluid communication with the orifice at the distal end of the stem and the collapsible container when the proximal end of the stem is attached to the spout, and whereby flow of the surgical prep solution to the pad is restricted;
- and
- the collapsible container comprises an original volume and a collapsed volume after dispensing of the surgical prep solution, the collapsible container recovering 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.
