  • Patent number: 11872558
    Abstract: A well plate assembly with an interior channel system in the well plate lid provides a more efficient and uniform distribution of fluid into a receptacle positioned below the well plate lid. The channel system in the lid allows air, or other fluid, to pass through with the use of a pump to each of a plurality of channels in the receptacle. Inlet and outlet valves in the lid prevent a gasket positioned between the lid and the receptacle from releasing contact with the receptacle due to high pressure experienced during the injection of fluid into the assembly. Specifically, pressure under a specified tolerance passes through the inlet valves, and if the pressure within the channel system exceeds the limit of the outlet valve, the outlet valve opens and allows air to escape the lid safely without disturbing the fluid flow into the channels below.

  • Patent number: 11806270
    Abstract: Certain embodiments relate to a soft odor barrier material in a medical device. The soft odor barrier material includes an elastomer and an antiblocking agent. In certain forms, the antiblocking agent imparts an interior rough surface having an arithmetic mean surface roughness (Ra) not less than 0.1 ?m. In certain forms, the antiblocking agent is non-blocking upon folding and packaging.

  • Publication number: 20220387258
    Abstract: In one aspect of the subject invention, a labeling shell is provided for a drug vial having a glass reservoir and an opening sealed by an elastomeric stopper, the labeling shell including: a polymeric tubular body formed to accommodate the reservoir of the drug vial, the tubular body having a first open end defining a first opening smaller than a diameter of the reservoir of the drug vial so as to prevent passage therethrough of the reservoir, wherein the elastomeric stopper is exposed through the first end with the reservoir being accommodated in the tubular body; and, a polymeric cap removably mountable to the tubular body to selectively cover the elastomeric stopper of the drug vial with the reservoir being accommodated in the tubular body. Advantageously, the subject invention provides a labeling surface for a drug vial, while also providing restricted access to the drug vial to limit tampering therewith.

  • Patent number: 11076978
    Abstract: A controlled discharge ostomy appliance assembly comprises (i) a stoma seal that is self-urging with a dynamic damping characteristic that resists changes of seal volume, (ii) a press-fit coupling member displaceable from an unlocked position to a locked position as part of a press-fit process, and (iii) a single-use frangible portion. The assembly further includes a protector shield removably fastened to the appliance forming a combined assembly therewith. The protector shield comprises (i) a seal displacer manipulable for displacing the stoma seal to a non-operative position ready for fitting, (ii) a substantially rigid coupling member guard portion for protecting the state of the coupling member, and (iii) a bracing portion for bracing the single-use frangible portion.

  • Patent number: 10695928
    Abstract: A rod slicer includes a receiving vessel, a cover vessel, and a rod mount. The rod mount may releasably couple with the cover vessel. At least one blade is mounted to or within the cover vessel. The rod mount has openings for one or more rods. The rod mount can be rotated, causing any rods in the openings to pass across from the rod mount into the cover vessel. In the cover vessel, a slicing edge of the blade, thus cutting a segment of a desired length from the rod. A pump may be connected to an opening in the vessel to vacuum the cut segments into the vessel. In some configurations, the blade is adjustable to change the length of the segments.

  • Patent number: 10576262
    Abstract: A spring-loaded bag connector having a spring-loaded valve and a housing comprising a fluid inlet portion and a fluid outlet portion. The spring-loaded bag connector is configured to connect with a fluid collection bag to generate a self-closing collection bag. Additionally, the spring-loaded bag connector is configured to couple with a second coupling element, such as a coupling connector, to facilitate the drainage and collection of waste to a fluid collection bag. Uncoupling of the bag connector and the second coupling element results in minimal fluid contamination on the outer surfaces of the bag connector system. The bag connector systems provided herein are included in medical appliances for body waste management.
