  • Patent number: 7918835
    Abstract: An aspiration instrument includes a compliant protective guard for minimizing injury to internal organs and other soft tissue while removing fluids from the body cavity. The compliant protective guard may be constructed from foam, plastic or other like material, including polyethylene and polypropylene. A preferred embodiment of the protective guard takes the shape of a bell. The compliant guard may be connected with the aspiration instrument using adhesives, such as glue or epoxy, or with a snap or friction fit. The compliant guard may define a single opening in fluid communication with the yankauer. The compliant guard may also define a plurality of openings for removing fluids from the body.

  • Patent number: 7794421
    Abstract: The present invention provides a coupling device for attaching a sleeve (40) to a surgical aspirator tip (10) that allows airflow between the external environment and the interior of the sleeve (40). The coupling device includes a male member (26) attached to the tip (10) and a female member (42) formed in the proximal end of the sleeve (40). The male member (26) includes at least one longitudinal groove (100). When the male member (26) is received into the female member (42), at least one venting channel (80) is defined between at least one longitudinal groove of the male member (26) and the inner surface of the female member (42). Venting channel (80) permits airflow between the external environment and the interior of the sleeve (40).

  • Patent number: 7776004
    Abstract: A surgical aspirator tip and sleeve combination includes a hollow aspirator tip adapted to be placed into communication with a suction source, a grip portion, a coupling portion extending distally from the grip portion, and a neck portion extending distally from the coupling portion. The surgical aspirator sleeve is receivable on the tip to define an internal channel between the sleeve and the neck portion. The internal channel is in fluid communication with the interior of the tip. A plurality of spaced orifices on the sleeve provide communication between the external environment and the internal channel. At least one longitudinal groove is formed at least partially within the grip portion and the coupling portion. The longitudinal groove defines a venting channel in communication with the internal channel and the external environment. The longitudinal groove is adapted to be at least partially covered to adjust the suction within the internal channel.

  • Patent number: 7762993
    Abstract: A catheter syringe conveyor with a needle guard housing is adapted to facilitate the insertion of a catheter into a targeted blood vessel. A catheter syringe is slidably situated within a hand-held housing structure; a syringe holder that is slidably connected to the housing allows a technician to maneuver the catheter syringe up and down within the housing. At least one stabilizer finger is attached to the bottom of the housing. After a blood vessel is penetrated by the needle of the catheter syringe, the technician maneuvers a catheter pusher to lower the catheter off of the needle and into the blood vessel. After the catheter is inserted, the technician is able to slide the catheter syringe back up within the housing to move the needle within the protective walls of the housing for safety, and a syringe lock holds it there securely for safekeeping.

    Abstract: A minimally invasive tracheal fluid removal device and corresponding method of use for removing accumulated subglottic secretions in an intubated patient's endotracheal tube. The device may be configured as a dual-track or single-tube suction guidance system. This device presents a significant improvement over the art as it eliminates the need to reintubate the patient each time the suction mechanism is removed to be cleaned.

  • Patent number: 7540860
    Abstract: A splashback shield for attachment to a syringe for wound irrigation includes a generally dome-shaped shield with a conduit or tunnel through the top that narrows to form a nozzle as it extends substantially inside the shield. A number of air vents or passageways surround the conduit so when submerging and re-filling the syringe with irrigant with the shield attached any air trapped inside the shield escapes rather than drawn into the syringe. The air vents are preferably elongate tubular passageways that narrow exiting the shield, facilitating air escaping but the irrigant mixed with any blood and contamination tends not to pass through the vents. The device is an improvement over the conventional Zerowet® Splashield® product.
