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.

Atomizer for nasal therapy

An anesthetic dispensing device () particularly adapted to apply anesthetic agent to the oral cavity and upper tracheal area of a medical patient prior to intubation of such patient. An exemplary dispenser () includes a handle () operably connected to a retractor () that carries an anesthetic dispensing device (). A currently preferred dispensing device () includes a fluid-dispersing nozzle () in fluid communication with a syringe (). Sometimes, an optical device () is coupled to the dispenser () to permit direct visualization of the application of anesthetic agent.

Atomizing nozzle for nasal therapy

A multi-access adapter operable to dispense doses of a medicament in succession from a bulk container, such as a vial. A preferred adapter may be used alone, or in combination with various discharge devices. A first preferred combination includes the adapter paired with a needle for injection of the medicament into one or more patients. A second preferred combination includes an atomizing nozzle affixed to the adapter and arranged for discharge of the medicament therethrough. Sometimes the atomizing nozzle carries a nostril guide structure that can be absorbent and may operate as a splash guard.

An apparatus for monitoring the intra-abdominal pressure of a 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 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 () and arranged to permit repetitive operation of a syringe () to inject a bolus of fluid into the patient's bladder (). Subsequent to making a pressure measurement, the urine valve () is returned to the bladder () draining position.

Intra-abdominal pressure monitoring device and method

An improved apparatus for monitoring the intra-abdominal pressure of a hospitalized patient includes a urinary catheter connected to a urine valve having selectable communication positions between a discharge end of the urinary catheter and either a drain or a fluid source. Preferably, the urine valve has a housing adapted to resist patient discomfort from leg-valve contact. One operable protective housing may be embodied as a separate tray component. 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 for communication to the fluid source, an infusion pump may be used to introduce a known quantity of fluid through the urine valve and into the patient's bladder where the fluid's pressure can be measured. Desirably, a double check valve is 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 making a pressure measurement, the urine valve is returned to the bladder draining position.

An apparatus for monitoring intra-abdominal pressure in a medical patient includes a urinary catheter connected to a urine valve having selectable communication positions between a discharge end of the urinary catheter and either a drain or a fluid source. Preferably, the urine valve has a housing adapted to resist patient discomfort from body-valve contact. A 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 for communication with the fluid source, a syringe may be used to introduce a known quantity of fluid through the urine valve into the patient's bladder where the fluid's pressure can be measured.
