A splash shield for use in wound irrigation comprises a three-dimensional shield member having a peripheral edge and a surface extending from the peripheral edge, the shield member being formed at least in part of flexible and pliant material for selectively shaping the peripheral edge to fit the shape or dimension of a wound, and an adjustable hub extending from the surface of the shield member configured to be circumferentially adjustable to adapt to the fluid end portion of any number and variety of irrigation fluid delivery devices. An attachable drain tube and a splash shield having an attached drain tube for removing fluid from the wound site is also disclosed.

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 ().

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.

Plumbing structure desirably maintains fluid supply and drain conduits in a substantially parallel arrangement to assist routing those conduits between a patient's legs.

A dilator system for insertion of a catheter or other elongate device into a body of a patient includes a catheter having a lumen that initially defines a first inner diameter. The catheter includes a swellable material that swells after insertion into the body. A dilator includes an elongate body that is initially disposed in the catheter lumen and a tapered head extending from a distal end of the catheter lumen. The dilator head defines an outer diameter that is larger than the first inner diameter of the catheter lumen. After insertion of the dilator head and a distal portion of the catheter into the body, the catheter swells such that the lumen defines a second inner diameter that is larger than the outer diameter of the dilator head. This enables the dilator to be proximally removed from the body via the catheter lumen defining the second diameter.

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.

A valved sheath introducer for venous cannulation, including a valve, sheath, handle and cap. The valve is configured to permit safe introduction and removal of medical instruments through the sheath introducer. The valve may have one or more anchoring members and a thickened central portion through which a slit is formed. The central portion may have one or more concave surfaces and the slit can be angled with respect to the top surface of the valve. The cap is attached to the handle, compressing a portion of the valve therebetween.

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.
