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 anesthetic dispensing device (100) 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 (100) includes a handle (110) operably connected to a retractor (112) that carries an anesthetic dispensing device (104). A currently preferred dispensing device (104) includes a fluid-dispersing nozzle (118) in fluid communication with a syringe (116). Sometimes, an optical device (164) is coupled to the dispenser (100) to permit direct visualization of the application of anesthetic agent.
摘要:
Devices adapted to facilitate draining fluid from the abdominal/peritoneal cavity of a medical patient. The invention may be embodied in one or more element of an access port, insertion assist device, and/or abdominal catheter. A preferred abdominal catheter provides a drain field that can be inserted into the abdominal compartment, through an access opening having a small cross-section, in a stowed configuration and subsequently expanded to provide a large drain area through which to extract fluid from the compartment.

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:
Described is an apparatus (100) adapted to temporarily close a surgical access opening (106) to a patient's body cavity (110). The apparatus includes a base (102) that is disposed around a perimeter of the opening, and a cap (104) that typically provides resealable access through the opening. The base generally forms an air-resistant seal to the patient's skin. In certain embodiments, the cap may be removable from the base. The base typically includes structure (180) configured to permit suction to be applied effective to remove undesired fluids from the body cavity. A cap is adapted to change in size to accommodate expansion and contraction of viscera.
摘要:
Described is, e.g., an apparatus (100), and associated methods of manufacture and use, for draining a fluid, discharged from a urinary catheter (104) installed in a subject's bladder, into a drain container (138) while avoiding undesired pressure states in such bladder. A drain conduit (102) connected to the catheter has a sufficiently small size as to maintain plug-flow between opposite ends of the drain conduit. The discharge end of the drain conduit is connected to a siphon-break apparatus (106) configured to cause a siphon-break disposed at an elevation (132) in approximate agreement with the subject's bladder. The potential energy from fluid downstream of the siphon-break location is decoupled from fluid in the drain conduit.

摘要:
An interface device and method for interfacing instruments to a medical procedure simulation system serve to interface peripherals in the form of mock medical instruments to the medical procedure simulation system computer to enable simulation of medical procedures. The interface device includes a housing having a mock bodily region of interest to facilitate insertion of a mock instrument, such as an endoscope tube, into the interface device. The mock bodily region of interest may be pivotable to simulate various patient orientations. The instrument is engaged by a capture mechanism in order to measure rotational and translational motion of the instrument. An actuator is disposed within the interface device to provide force feedback to the instrument. The measured motion is provided to the computer system to reflect instrument motion on the display during the simulation. Alternatively, the interface device may be configured to accommodate instrument assemblies having a plurality of nested instruments (e.g., sheath, catheter and wire), whereby the interface device individually grasps, measures manipulation of and provides force feedback to the nested instruments. In addition, the interface device may be configured to simultaneously accommodate a plurality of independently inserted instruments.
