Abstract: Systems and methods for designing and optimizing tools are provided. A computational fluid dynamics (CFD) simulation model implemented by a processor is provided to simulate a fluid flow inside the tool to generate a particle density distribution of fluids inside the tool. The particle density distribution is converted to a spatial distribution of fluid concentration of the mixture which allows for high resolution visualization of fluid flow in the tool.

Abstract: A securement device for securing a medical article, comprising abase having a longitudinal axis, a top face and a bottom face, where the longitudinal axis defines a longitudinal direction, a cuff disposed on the top face of the base and positioned along the longitudinal axis, the cuff comprising an entry gap in at least a portion of the cuff and defining an interior aperture, and a bar disposed on the top face of the base, the bar positioned along the longitudinal axis, where the bar is moveable between an open position and a closed position and where the bar cooperates with the cuff in the closed position to secure the medical article.

Abstract: A securement device for securing a medical article is disclosed. The securement device comprises a base and a first securing portion comprising a strap that is movable between an open position and a closed position and a connector disposed on the base. The strap cooperates with the connector in the closed position to form an enclosure. The strap further comprises a curvilinear segment that projects inwardly into the enclosure in a convex orientation when the strap is in the closed position. Securement systems for securing medical articles and methods of securing at least a portion of a medical article to a patient are also provided.

Abstract: Brackets, systems comprising a bracket, and methods for securing medical articles. The bracket can include a base, a post coupled to the base and extending upwardly from the base in a direction generally normal to a first major surface of the base, and an arm coupled to the base and extending generally parallel to the first major surface of the base. The arm can be spaced a distance from the first major surface of the base to define a channel under the arm that is dimensioned to receive at least a portion of the medical article. The arm can be cantilevered, and the post and the arm can each be fixed with respect to the base. Methods can include abutting an external surface of the medical article against the post; and moving a portion of the medical article into the channel defined by the arm.

Abstract: A graphic for use with medical article securement systems, medical article securement systems comprising a graphic, and methods of using same. The graphic can include a representation of an anatomical feature, such that the graphic provides a visual cue for coupling the medical article securement system to a subject in a desired orientation relative to the subject. Medical article securement systems comprising a graphic can be configured to be coupled to the subject and further configured to secure at least a portion of a medical article. Methods can include coupling the medical article securement system to the subject according to the graphic.

Abstract: A medical article securement system comprising a bracket and a flap for securing a medical article. The bracket can include a base, and an arm coupled to the base and extending generally parallel to the first major surface of the base. The arm can be spaced a distance from the first major surface of the base to define a channel under the arm that can be dimensioned to receive at least a portion of the medical article. The flap can include a fixed end, and a free end that is movable with respect to the bracket between a first position in which the flap is not positioned over the bracket, and a second position in which at least a portion of the flap is positioned over the bracket to further inhibit movement of the medical article. The fixed end of the flap can be coupled to the bracket.

Abstract: A harness assembly for a respiratory protection device is provided. In an exemplary embodiment, the harness assembly includes a strap support having an attachment point, a first strap having a first strap attachment element, and a second strap having a second strap attachment element, wherein the first strap attachment element is attachable to the second strap attachment element and attachable to the attachment point of the strap support, and the first and second straps are positionable between the first configuration in which the first strap attachment element is attached only to the second attachment element and a second configuration in which the first attachment element is attached to the second attachment element and the attachment point of the strap support.
