Abstract: A retainer is provided comprising a ring configured to fit over a readily available tracheostomy tube and be securable thereto, and further having cooperating straps configured to extend around and secure an auxiliary device coupled to the tracheostomy tube, such as a ventilator tube. The retainer is configured to be selectively and easily attachable to existing tracheostomy tubes to provide a platform for securing an auxiliary device.

Abstract: The improved medical nebulization device includes a head and a removeable depending liquid reservoir. The head has a closed top, closed sides and open bottom defining a central space in which is secured a nebulization chamber having closed sides and an open top and open bottom. A nebulization baffle is connected to the head top and extends into the nebulization chamber. A liquid draw tube is connected to the baffle and depends from the chamber into the reservoir. A nebulized aerosol output port extends between the space outside the chamber and a point peripheral of the head for supplying nebulized aerosol to a patient. An auxiliary multiple gas entrainment inlet port, with removeable cap, extends into the chamber at a point remote from the output port and is adapted to supply auxiliary gases such as a mixture of oxygen and helium. The liquid reservoir in one embodiment includes a graduated liquid measuring scale and is transparent.

Abstract: The improved endotracheal anti-disconnect device includes a flexible, resilent elongated patient neck band having a main body, the front surface of which bears a number of hook-receiving loops. The band has narrow opposite ends which form tabs, the front surfaces of which bear a number of hooks. With this arrangement the tabs can be passed through slots in the sides of an endotracheal tube bracket and then can be reflected rearwardly and connected by the hooks to the loops to releasably hold the bracket against the throat of a patient. The device also includes a ring assembly having a ring with a central space and to which ring are connected 4 connectors, which radiate therefrom. Two of the connectors are in the form of wings which are disposed horizontally and are elongated. The wings bear a number of hooks on their inner surfaces so that the ring can be pulled against the bracket and connected by the wings to the front surface of the neck band.

Abstract: The improved endotracheal bite block includes an elongated bite tube having a central endotracheal tube-receiving cavity extending therethrough to the front and rear ends of the bite tube. The bite tube is relatively inflexible and has an elongated post extending rearwardly thereof. The post has a strap-receiving slot therein and a rear retaining wall extending laterally outwardly for releasably holding an adhesive strip in place on the bite block, which tape also is used to hold an endotracheal tube against the bite block. The bite block further includes an elongated flexible strap with a strap retainer at one end and an opposite free end which can be passed through the slot and around an endotracheal tube and then can be cinched up to anchor the endotracheal tube and bite block together. Preferably, the bite tube is C-shaped in cross-section and single walled.

Abstract: The improved device is used in the present method for cleansing the head of a stethoscope with an antimicrobial spray liquid. The device includes a housing which defines a generally central cavity in which an aerosol spray cannister is releasably disposed in a bracket. The housing is closed but is openable in order to replace the cannister, as needed. The housing includes an openable port, such as an elastomeric iris, through which the head of a stethoscope, in accordance with the present method, is inserted for cleansing in the cavity. The cannister has a spray nozzle which is activatable by a trigger in the form of a lever secured in the cavity and extending out of the housing. The lever is disposed above the nozzle and can be manually moved from outside the housing to depress the nozzle and cause antimicrobial spray to be aerosol dispensed from the cannister in a path in the cavity which the stethoscope head intersects.

Abstract: The invention comprises an improvement for an automotive engine cooling testing system wherein a coolant reservoir is connected to the instrument module by means of two quick disconnect fittings; each such fitting is provided with an internally located shut-off valve that is actuated to close when a disconnection is made. The improvement provides a convenient way to bleed air out of the cooling system prior to commencement of a testing routine, therefore providing a more accurate test result.
