Publication number: 20230211079Abstract: An intravenous delivery system may operate by gravity feed, and may have a liquid source containing a liquid, a drip unit that receives the liquid from the liquid source, and tubing that receives the liquid from the drip unit for delivery to a patient. A flow rate sensor may be used to measure a flow rate of liquid through the intravenous delivery system, and may generate a flow rate signal indicative of the flow rate. A controller may receive the signal, and may compare the flow rate with a desired flow rate. If the flow rate is more or less than the desired flow rate, the controller may transmit a control signal to a flow rate regulator. The flow rate regulator may receive the control signal and, in response, modify the flow rate to bring the flow rate closer to the desired flow rate.Type: ApplicationFiled: March 9, 2023Publication date: July 6, 2023Inventors: S.

Publication number: 20230204464Abstract: Contamination detection systems, kits, and techniques are described for testing surfaces for the presence of hazardous contaminants, while minimizing user exposure to these contaminants. Even trace amounts of contaminants can be detected. A collection kit provides a swab that is simple to use, easy to hold and grip, allows the user to swab large areas of a surface, and keeps the user's hands away from the surface being tested. The kit also provides open and closed fluid transfer mechanism to transfer the collected fluid to a detection device while minimizing user exposure to hazardous contaminants in the collected fluid. Contamination detection kits can rapidly collect and detect hazardous drugs, including trace amounts of antineoplastic agents, in healthcare settings at the site of contamination.Type: ApplicationFiled: February 15, 2023Publication date: June 29, 2023Inventors: Weston F.

Publication number: 20230012604Abstract: The present invention relates to a multiple-use intravenous (IV) catheter assembly septum and septum actuator. In particular, the present invention relates to an IV catheter assembly having a stationary septum actuator and a blood control septum, wherein the blood control septum is configured to slide within a catheter adapter of the IV catheter assembly between a compressed state and an uncompressed state. When in the compressed state, a slit of the blood control septum is opened and the septum comprises stored compressive potential energy. When the septum is released from the compressed state, the stored compressive potential energy is release and the blood control septum is restored to its original shape, thereby closing the septum's slit.Type: ApplicationFiled: September 21, 2022Publication date: January 19, 2023Inventors: Darin Charles Vincent, S.
