  • Patent number: 9668909
    Abstract: A gastrojejunostomy tube is used when a patient's stomach must be bypassed, with nutrients and/or medication being delivered directly to the jejunum. In this situation, the stomach commonly fills with stomach acid and digestive enzymes, which may cause vomiting, acid reflux or other esophageal problems. The gastrojejunostomy drainage bag is provided to allow the contents of the stomach to be drained through the gastrojejunostomy tube, rather than building up within the patient's stomach. The gastrojejunostomy drainage bag includes a receptacle having a lower portion and an upper stem portion, the upper stem portion terminating in a port adapted for connection to the gastrojejunostomy tube. Preferably, a lower port is formed through the lower portion, allowing the contents of the gastrojejunostomy drainage bag to be selectively emptied. A method of releasing gas or trapped air from the stomach is also disclosed.

    Abstract: A system and method are disclosed for automatically limiting the drainage of a bodily fluid such as cerebrospinal fluid (CSF) from a patient into a collection chamber. The collection chamber includes a vent having an hydrophobic filter for the passage of air to facilitate the movement of CSF yet to maintain a closed system. The system includes a buoyant float hingedly connected with the top of the collection chamber in one embodiment. When fluid rises in the collection chamber to a predetermined volume, buoyant force raises the float and causes a seal plug mounted on top of the float to seal one of an inflow port or a vent port. The float is limited to pivoting movement in one plane and to a certain angle within that plane. The system and method avoid overdrainage of CSF from the patient and overfilling of the collection chamber.

  • Patent number: 8317753
    Abstract: A compact, nonelectric fluid dispenser for use in controllably dispensing beneficial agents such as propofol and dexmedetomidine hydrochloride to patients. The dispenser includes a fluid flow control assembly that precisely controls the flow of the medicament solution to the patient and embodies a collapsible drug container that can be filled in the field with the beneficial agents to be delivered to the patient. The unit-dose fluid dispenser of the invention is presented in a sterile and aseptic manner, where the drug has been pre-filled in the system, so that the practitioner cannot mistakenly give the wrong drug to the patient. The dispenser uniquely provides a more efficient medicament delivery system for procedure rooms, such as the endoscopy center, so that a greater number of patients can be treated per day at a higher standard of care with increased profits for the healthcare provider.

  • Patent number: 8292858
    Abstract: A drain bag outlet device includes inlet, valve and outlet portions. The inlet portion includes a connector and a cylindrical portion. The connector is adapted to connect to a fluid drain bag. A second end of the connector is adapted to connect to the cylindrical portion forming a generally longitudinal opening therethrough. The valve portion is attached to a second end of the cylindrical portion and includes a valve member for moving between positions to permit and obstruct fluid flow through the longitudinal opening. The outlet portion includes an outlet member having an angled portion and a shield connected to the valve portion. The shield completely surrounds and extends below the outlet member. The shield includes upper and lower portions. The diameter of the upper is less than the diameter of the lower portion. The outlet device eliminates the fluid that is spilled, splashed or sprayed on a healthcare worker.

  • Patent number: 8221366
    Abstract: A system and method are disclosed for automatically limiting the drainage of a bodily fluid such as cerebrospinal fluid (CSF) from a patient into a collection chamber. The collection chamber includes a vent having an hydrophobic filter for the passage of air to facilitate the movement of CSF yet to maintain a closed system. The system includes a buoyant float hingedly connected with the top of the collection chamber in one embodiment. When fluid rises in the collection chamber to a predetermined volume, buoyant force raises the float and causes a seal plug mounted on top of the float to seal one of an inflow port or a vent port. The float is limited to pivoting movement in one plane and to a certain angle within that plane. The system and method avoid overdrainage of CSF from the patient and overfilling of the collection chamber.

  • Patent number: 8187227
    Abstract: A barrier of a vacuum pump prevents contamination from entering a vacuum pump air line. The barrier separates parts of the pump and is moveable between an initial state and a distended state. The barrier is assembled within the pump with a pre-load. When the vacuum source is applied to the barrier, the barrier achieves a distended state and when the vacuum source is released, the barrier incrementally self returns to an initial state. The geometry and material construction of the barrier, along with the pre-load, assists in returning the barrier on its own to the initial state from the distended state.
