  • Patent number: 11219752
    Abstract: An in-line connector for use in an enteral feeding system includes a tamper-proof, single-use connector having a first component connectable to a first feeding device of the feeding system, and a second component connectable to a second feeding device of the feeding system. A releasable locking mechanism is provided such that the first component and the second component do not rotate when connected. The connector further includes one or more prongs positioned substantially flush against an interior wall of the second component when the first component and the second component are connected such that the prongs do not interfere with the releasable locking mechanism. Meanwhile, the one or more prongs are displaced away from the interior wall when the first component is detached or disconnected from the second component such that the second component resists re-insertion or reattachment of the first component.

  • Patent number: 11166881
    Abstract: Devices for cleaning a tube or clearing a blockage from a tube, such as an enteral feeding device are provided. The devices include an actuator and a syringe. The actuator is releasably attached to the syringe in a manner that allows the actuator to transition the syringe from a compressed position to an extended position, and vice-a-versa, without requiring the intervention of a user. A method of cleaning a tube or clearing a blockage in a tube is also provided. The tube cleaning device is filled with a liquid and the actuator pushes the liquid from the syringe into the tube when transitioning into a compressed position, and withdraws the liquid back into the syringe when transition into an extended position, causing the liquid to contact a blockage, and clear the blockage and/or clean the tube.

  • Publication number: 20210030629
    Abstract: A tubing assembly for use with electronic catheter guidance systems is provided and includes a catheter and an acoustic sensor. The catheter extends in a longitudinal direction and has a proximal end and a distal end that define a lumen therebetween. Further, the catheter is configured for placement within a patient's digestive tract. The acoustic sensor can be located within the lumen of the catheter or in a sampling chamber connected to the catheter. The acoustic sensor can communicate with a processor to deliver sound data to a display device. The appearance of random spikes on a frequency versus time spectrogram can indicate placement of the catheter in the digestive tract, while a rhythmic/repetitive pattern on a frequency versus time spectrogram can indicate placement of the catheter in the respiratory tract. A catheter guidance system and method for accurately placing a catheter in the digestive tract are also provided.

  • Publication number: 20200306141
    Abstract: A tubing assembly for use in conjunction with electronic catheter guidance systems is provided and includes a catheter and a sensor. The catheter extends in a longitudinal direction and has a proximal end and a distal end that define a lumen therebetween. Further, the catheter is configured for placement within a digestive tract of a patient. The sensor includes a temperature sensor, relative humidity sensor, or both, and can be located within the lumen of the catheter or in an air sampling chamber connected to the catheter. The sensor can communicate with a processor to deliver temperature and/or relative humidity readings to a display device. A constant temperature or relative humidity profile, or both after a pre-determined amount of time can indicate placement of the catheter in the digestive tract. A catheter guidance system and a method for accurately placing a catheter in the digestive tract are also provided.
