Patent number: 9265898Abstract: 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.Type: GrantFiled: September 12, 2008Date of Patent: February 23, 2016Assignee: Wolfe Tory Medical, Inc.Inventors: Govind R.

Publication number: 20150038904Abstract: A syringe structured to permit multiple filling and emptying cycles with a single syringe, but then to automatically disable that syringe to resist syringe reuse subsequent to a final dose-ejecting cycle. The syringe includes a plunger with a distal tip carrying capture structure that protrudes from the dispensing aperture of the syringe at a fluid fully-expelled position. A fluid discharge attachment can be coupled to the syringe to guide dispensing one or more dose of treatment substance. A first locking element, typically carried by the fluid discharge attachment, couples with the capture structure to resist retraction of the fully-depressed plunger, and thereby resists reciprocation of the plunger to prevent reuse of the syringe. Effectively, the discharge aperture of the syringe is pinned between an internally disposed stopper and the external capture structure.Type: ApplicationFiled: March 22, 2013Publication date: February 5, 2015Applicant: Wolfe Tory Medical, Inc.Inventors: Marshall T. Denton, Perry W. Croll, Mark A. Christensen, Huy N. Tran

Publication number: 20130298902Abstract: 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.Type: ApplicationFiled: November 11, 2011Publication date: November 14, 2013Applicant: WOLFE TORY MEDICAL, INC.Inventors: Marshall T.

Publication number: 20130277443Abstract: Described is an atomizing nozzle having a relatively small frontal area permitting insertion of a nozzle into small diameter medical conduit(s). A body of a preferred nozzle has a characteristic size (e.g., cross-section diameter) of less than about 0.2 inch (0.5 cm). The nozzle body is typically carried on an extension member, which can be transversely flexible to permit passage of a nozzle body through a tube and along a nonlinear path. The nozzle body is typically connected to an extension member by way of a lap joint associated with the nozzle body. Preferred embodiments have a De/O ratio of less than 12.0, a Db/O ratio of less than about 18, and a Db/De ratio of less than about 1.1. Certain embodiments include a swirling chamber disposed upstream of the ejection orifice and having a proximal wall with a portion configured to at least approximate a portion of a dome, or other curved surface.Type: ApplicationFiled: October 20, 2010Publication date: October 24, 2013Applicant: WOLFE TORY MEDICAL, INC.Inventors: Perry W.

Patent number: 7726328Abstract: 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.Type: GrantFiled: August 26, 2009Date of Patent: June 1, 2010Assignee: Wolfe Tory Medical, Inc.Inventors: Mark A.

Publication number: 20080103408Abstract: A device structured to generate an input signal to a monitor (201) to visually indicate a value for one or more physiological state variables measured by one or more transducers (203) associated with a medical patient. Preferred embodiments include a pressure transducer (195) placed in fluid communication with the patient's bladder (177) effective to infer intra-abdominal pressure P2. Embodiments may also include a temperature transducer (143) configured to measure the temperature of fluid in/near the bladder (177) to infer core body temperature. Certain embodiments of the invention may include a second pressure transducer (235) configured to measure arterial blood pressure. In the latter case, signals received from the two pressure transducers (177, 235) may be manipulated to produce a third signal corresponding to abdominal perfusion pressure, which can then be indicated on a numeric display device (233).Type: ApplicationFiled: November 21, 2005Publication date: May 1, 2008Applicant: Wolfe Tory Medical, Inc.Inventors: Marshall T.

Patent number: 7112177Abstract: 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.
