  • Publication number: 20240132931
    Abstract: A growth medium for a biological indicator is provided. The growth medium can include a base growth medium as well as an additive. The additive can include a carbon source unit, such as, but not limited to, glucose, and a volatile organic compound unit. Alternatively, the additive can include a carbohydrate source. The present invention is also directed to a self-contained biological indicator (SCBI) that includes a container, spores disposed on a carrier, a growth medium, and an additive. The additive can include a carbon source unit or a molecule containing a part that can form a VOC when reduced or oxidized, such as, but not limited to glucose, and a volatile organic compound unit. Alternatively, the additive can include a carbohydrate source. It has been found that the addition of such additives to the growth medium facilitates the efficient and accurate detection of a failed sterilization process.

  • Publication number: 20240110217
    Abstract: A method for determining if a spore in a self-contained biological indicator is in a germination phase is provided. The method includes subjecting a self-contained biological indicator to a sterilization process; exposing spores in the self-contained biological indicator to a growth medium; incubating the spores in the self-contained biological indicator; sampling headspace in the self-contained biological indicator; and determining if a volatile organic compound attributable to the germination phase of the spores in the biological indicator is released into headspace upon contact with the growth medium, wherein the presence of the volatile organic compound attributable to the germination phase of the spores in the self-contained biological indicator indicates failure of the sterilization process. A method for determining if a sterilization process was successful or was a failure by measuring VOC concentration is also provided.

  • Publication number: 20240110218
    Abstract: A biological indicator system for determining the efficacy of a sterilization process is provided. The system includes a radiofrequency identification sensing board having a radiofrequency identification tag, a microcontroller/digital electronics, a sensing pad, and a circuit coupled to the sensing pad that measures an impedance level or a resistance level of the sensing pad upon exposure to a volatile organic compound. The radiofrequency identification tag includes a radiofrequency integrated circuit and an antenna that communicates wirelessly with a radiofrequency identification reader to transmit data associated with the impedance or resistance levels measured from the sensing pad. The data can be transmitted in real-time during incubation, and this data can then be sent to a user interface to determine the efficacy of a sterilization process when the biological indicator system is placed in a sterilization chamber during a sterilization cycle. A method of using the system is also provided.

  • Patent number: 11639577
    Abstract: An automated method is provided for forming pleats in a textile product in a production line. The method includes conveying a web of the textile product on a conveyor in the production line. The web is folded using a folding board at a folding station in the production line. The method includes removing heat from the folding board. The automated method can allow for high speed folding of the textile product without damaging the textile product from heat caused by friction between the web of textile product and the folding board.

  • Patent number: 11220362
    Abstract: An automated system and method wrap the fastening ties around the body of a continuous stream of facemasks in a facemask production line. The facemasks are oriented such that each facemask has a leading pair of ties and a trailing pair of ties extending from a body in a conveying direction of the production line. The leading pair of ties is drawn below the body as the facemask continues to be conveyed in the conveying. The body is conveyed through a plurality of conveyor sections oriented at angles such that the conveying direction of the body changes at a junction from one conveyor section to an adjacent conveyor section. At the junctions between conveyor sections, an impinging force is directed against the body that causes the body to flip, thereby causing the leading and trailing pairs of ties to further wrap around the body.

  • Patent number: 10987811

The facemasks are oriented such that each facemask has a leading pair of ties and a trailing pair of ties extending from a body in a conveying direction of the production line. At a wrapping station in the production line, the body is subsequently clamped with a clamping device of an automated robotic arm. The robotic arm is driven in the conveying direction while rotating the clamping device and body relative to a rotation axis through the body to cause the leading and trailing pairs of ties to wrap around the body. The robotic arm then deposits the facemask with wrapped ties onto the conveyor.

  • Patent number: 10940225
    Abstract: Sterilization packaging systems with features for sealing a volume against an ingress of contaminants are provided. Such features include a sealing assembly including a gasket and a sheet of filter material. The sealing assembly seals a lid to a seal rim of a base. The gasket has an upper surface, outer edge, and inner edge. The upper surface of the gasket comprises a first row of alternating protrusions and indentations and a second row of alternating protrusions and indentations that define a channel therebetween. The sheet of filter material extends from an inner edge of the gasket. The gasket completely surrounds the sheet of filter material, wherein the indentations and channel facilitate delivery of a sterilization agent through the filter material. A sterilization assembly including a lid having a plurality of protrusions in its upper surface in conjunction with a gasket having a smooth upper surface is also provided.

  • Patent number: 10813393
    Abstract: An automated system and method for the manufacture of facemasks from a web of a textile product in a production line is provided. The web is conveyed in the production line along a machine direction. A first tie is attached at a tie attaching station to the web of the textile product, such that the first tie extends from the web in a cross-machine direction perpendicular to the machine direction. The web and first tie are cut at a cutting station in the cross-machine direction across a width of the web in the cross-machine direction to form a facemask separate from the web.
