Abstract: Sterilization packaging systems with features for sealing a volume against an ingress of contaminants are provided. Such features include a frame including a plurality of vertical members and a plurality of horizontal members, each vertical member and horizontal member having an inner side and an outer side; a sterilization wrap, a first portion of the sterilization wrap positioned adjacent the inner side of each vertical member and each horizontal member to define a volume and an opening to access the volume; and a lid for sealing the volume against an ingress of contaminants. Additionally, a sterility gauge for signaling whether the volume is sealed against contaminants also may be provided. Exemplary sterilization packaging systems may include other features as well.

Abstract: A method and system are provided for placing nose wires in a facemask production line. A supply of individual pre-cut nose wires are supplied to a dispenser in the production line. With the dispenser, the nose wires are metered at a defined spacing and orientation onto a running carrier web that is conveyed past the dispenser. The carrier web and nose wires deposited thereon are conveyed to a folding station wherein a binder web is folded over an edge of the carrier web such that the nose wires are encapsulated between the binder web and the carrier web.

Abstract: A protective disposable facemask includes a body having a top edge and a bottom edge, the top and bottom edges cooperating with each other to define a periphery that contacts a wearer's face. A first reactant material is deposited along the top edge, the first reactant material having a malleable unreacted state such that the top edge is conformable across the wearer's nose and face in the unreacted state. The first reactant material is reactable with a second reactant material to form a stiffened nose member that retains the conformed shape across the wearer's nose and face. A method of manufacturing the facemasks is also encompassed.

Abstract: An automated method and system for preparing facemask for subsequent stacking and packaging in a facemask production line include conveying individual facemasks in an alternating and offset nesting pattern on a first conveyor at a first conveying speed. The facemasks are transferred to a second conveyor having a second conveying speed that is greater than the first conveying speed so that an increased gap is generated between adjacent facemasks. The aligned facemasks are wrapped at an automated in-line wrapping station wherein a continuous wrapping material is bonded around each individual facemask. At an in-line cutting station, the bonded wrapping material is cut between each adjacent facemask.

Abstract: The present disclosure describes a draping system for a two-tiered hospital instrument back table can be used to quickly and conveniently create a sterile field. The system has a drape that is a single piece of material, desirably a film that may be clear. The single piece of material has other material attached to it on its upper side or surface in areas that generally coincide with the two upper surfaces of the table when the drape is installed on the table, and that has a lower coefficient of friction than the single piece of material. The drape may be held in place with a continuous or discontinuous band that encircles the upper tier or the upper tier support posts.

Abstract: A method and system are provided for splicing a reserve nose wire to a running nose wire in a facemask production line. Prior to depletion of the running nose wire, a reserve nose wire is brought up to a transport speed in a conveying direction of the running nose wire. At or near a zero relative speed between the running nose wire and the reserve nose wire, a leading end of the reserve nose wire is introduced onto the running nose wire, and the two wires are spliced together. The running nose wire is then cut upstream of the splice location such that the reserve nose wire becomes a new running nose wire in the production line.

Abstract: A method and associated system are provided for splicing a reserve nose wire to a running nose wire in a facemask production line, wherein the running nose wire is supplied continuously from a supply roll. Prior to depletion of the running nose wire, the supply roll is moved from an operating location to an intermediate location that is further from the production line while continuing to supply the running nose wire from the supply roll. The supply roll is then moved from the intermediate location back towards the production line while decelerating the supply roll to a stop, thereby creating an accumulation of the running wire functionally between the supply roll and the production line. With the supply roll at a stop, the running nose wire is continuously supplied from the accumulation and a leading end of a reserve roll of nose wire is spliced to the running nose wire at a location upstream of the accumulation where the running nose wire is at a standstill. The running nose wire is then cut at a location upstream of the splice such that the reserve nose wire and reserve roll become a new running nose wire and new supply roll in the production line.

Abstract: A multi-layered face mask coated with discontinuous patterns of phase change material are incorporated into the face mask construction to provide for cooling of the microclimate in the dead space of the face mask. Optimized cooling is achieved by strategic placement of layers coated with a phase change material within the mask construction and the amount and density of the phase change material in contact with the temperature sensitive areas of the face, as well as areas experiencing the maximum amount of flux from exhaled breath. The shape of the mask can also be adjusted to increase skin contact with the phase change material and decrease dead space volume, which reduces the volume of warm exhaled air and can provide sufficient cooling with less phase change material. The discontinuous patterns of phase change material also provide inter-layer spacing between the layers of the mask, which can improve splash resistance.

Abstract: A method and associated system for cutting and placing individual nose wires in a facemask production line include supplying a continuous wire from a supply source to a cutting station where the continuous wire is cut into individual nose wires having a defined length. The nose wires are then conveyed to a treatment station prior to being deposited onto a carrier web. At the treatment station, a surface treatment is performed on a side of the nose wires that results in an increased surface attachment of the nose wires to the carrier web.

Abstract: Sterilization packaging systems with features for sealing a volume against an ingress of contaminants are provided. Such features include a sealing assembly, where the sealing assembly includes a sheet of sterilization material and a clamp for sealing the sheet of sterilization material against a container to seal the volume of the container from contaminants. Also provided is a sealing assembly including a sheet of sterilization material and a clamp having open position and clamped positions. The clamp is configured to extend about a perimeter of a container, the sheet of sterilization material is disposed between the container and the clamp when the clamp is in the clamped position to seal a volume of the container, and the clamp is held in the clamped position by a latch. Exemplary sterilization packaging systems may include other features as well.
