  • Publication number: 20220265924
    Abstract: A system for monitoring upstream flow characteristics for a pump is provided. The system may receive one or more outputs from a fluid level sensor coupled with a pump. The system may detect based on at least the one or more outputs, an abnormal upstream flow condition in the pump, such as a full upstream occlusion in the tube, a partial upstream occlusion in the tube, an empty reservoir, and/or a backflow of the fluid into the drip chamber. The system may adjust, based on the detection of an abnormal upstream flow condition in the pump, operation of the pump.

  • Patent number: 10173003
    Abstract: A system and a method are adapted for assessing the patency of a fluid infusion line connected to a patient, a source of medicant, and a pump. The system is configured for injecting a fluid into the fluid pressure line using a syringe, determining whether the syringe exhibits a resistance to fluid being injected into a the fluid line and, if no resistance is exhibited, monitoring the pump to verify whether the pump exhibits an alarm that indicates a check valve has been opened.

  • Patent number: 10124158
    Abstract: A clamp for clamping flexible tubing is disclosed. The clamp includes a body having a first portion, a second portion, a first passage through the first portion, and a second passage through the second portion. The first passage is configured to compress a first length of the flexible tubing. The second passage is configured to compress a second length of the flexible tubing that does not overlap the first length.

  • Patent number: 9050447
    Abstract: A clamp for clamping flexible tubing is disclosed. The clamp includes a body having a first portion, a second portion, a first passage through the first portion, and a second passage through the second portion. The first passage is configured to compress a first length of the flexible tubing when the flexible tubing is displaced laterally into the first passage. The second passage is configured to compress a second length of the flexible tubing that does not overlap the first length when the flexible tubing is displaced laterally into the second passage.
