摘要： An apparatus for monitoring fluid pressure includes a reusable base section, and a disposable dome section detachably connected to the base section. The disposable dome section defines a fluid pathway and includes a dome viewing segment in fluid communication with a flush segment and a stopcock segment. A pressure transducer sensor is disposed in the reusable base section and is adapted to produce electrical signals proportional to fluid pressures sensed in the fluid pathway. A usage indicator can be disposed in the base section to provide a visual indication of usage of the apparatus within a predetermined number of uses. A calibration port can be provided in the base section to allow for simple calibration by the user without violating the sterility of the apparatus. The ability to reuse the base section with the sensor component reduces the cost of the apparatus, while the disposability of the dome section with the fluid pathway ensures sterility for each use.

摘要： An atomizing nozzle structured particularly for nasal therapy. Preferred embodiments include a 2-piece atomizing nozzle structured to couple with luer-locking structure carried by a syringe. Such an atomizing nozzle includes a nasal stopper and a stem. A preferred nasal stopper includes a distal tip sized for insertion into a nostril of a human child, with a proximal shield portion being structured to resist over-insertion of a discharge orifice into the nostril. A nasal stopper desirably provides a centering function to urge the discharge orifice away from a nasal wall. One operable stem is structured to couple with the stopper and desirably carries unitary thread structure at a proximal end. A second operable stem is structured as a unitary part of the nasal stopper and also desirably carries unitary thread structure at a proximal end. Certain embodiments may also include spacer structure configured to reduce a dead volume inside the atomizing nozzle. Other embodiments may also include spacer structure configured to reduce dead volume inside a syringe that is coupled to the atomizing nozzle.

摘要： An apparatus for monitoring the intra-abdominal pressure of a hospitalized patient includes a urinary catheter connected to a urine valve providing selectable communication between a discharge end of the urinary catheter and either a drain or a fluid source. Preferably, the urine valve is adapted for remote actuation and has a housing adapted to resist patient discomfort from leg-valve contact. Plumbing structure desirably maintains fluid supply and drain conduits in a substantially parallel arrangement to assist routing those conduits between a patient's legs. When the urine valve is oriented to permit communication with the fluid source, an infusion pump may be used to infuse a known quantity of fluid through the urine valve and into the patient's bladder. A pressure transducer desirably is connected in-circuit to indicate the fluid's pressure. To facilitate the infusion process, an automatic flow control device may be included in a fluid supply path and arranged to permit repetitive operation of a syringe to inject a bolus of fluid into the patient's bladder. Subsequent to a period of time in which to make a pressure measurement, preferred embodiments of the urine valve automatically return to a bladder draining position.

摘要： A temporary airway that can be used to facilitate an intubation procedure. Desirably, the temporary airway is removable from an installed intubation conduit without requiring disassembly of the intubation system and interrupting breathing treatment of the patient. Certain embodiments include an intubation lumen, and a treatment lumen. The intubation lumen is configured to assist in guiding an intubation conduit into operable position in a medical patient. The treatment lumen is operable to apply an anesthetic agent, and/or treatment fluids, including gas, such as Oxygen or compressed air. Certain treatment lumens are associated with a fluid dispersion nozzle, most preferably an atomizing nozzle.

摘要： An apparatus for monitoring the intra-abdominal pressure of a patient includes a urinary catheter (102) connected to a urine valve (250) providing selectable communication between a discharge end of the urinary catheter (102) and either a drain (224) or a fluid source (104). Preferably, the urine valve (250) is adapted for remote actuation and has a housing adapted to resist patient discomfort from leg-valve (250) contact. Plumbing structure desirably maintains fluid supply (225) and drain (223) conduits in a substantially parallel arrangement to assist routing those conduits (225, 223) between a patient's legs. When the urine valve (250) is oriented to permit communication with the fluid source (104), an infusion pump (116′) may be used to infuse a known quantity of fluid through the urine valve (250) and into the patient's bladder (216). A pressure transducer (218) desirably is connected in-circuit to indicate the fluid's pressure and avoid pressure fluctuations induced by system components. To facilitate the infusion process, an automatic flow control device may be included in a fluid supply path (225) and arranged to permit repetitive operation of a syringe (116′) to inject a bolus of fluid into the patient's bladder (216). Subsequent to making a pressure measurement, the urine valve (250) is returned to the bladder (216) draining position.

摘要： A fluid delivery valve for use in fluid conducting systems includes a rigid bracing member positioned within a hollow, flexible, resilient valve housing. By applying opposing lateral forces to the external surface of the housing near a widened portion of the bracing member, the valve housing deforms around the widened portion and the valve is actuated. Actuating the valve permits fluid communication between the inner chamber of the valve housing, and a channel which extends through an enlarged portion. The channels are sealed by the inner wall of the housing when the opposing forces are released. The fluid is thus selectively allowed to travel past the bracing member.
