The retention system also includes an inflatable balloon located at a distal end of the tube in fluid communication with the inflation lumen, the balloon having thin, flexible walls, a predetermined spheroid shape, and a volume at which a fluid in the balloon is under no pressure such that upon inflation with a fluid to pressurize fluid in the balloon, the balloon assumes a stable spheroid shape and exhibits a substantially linear pressure versus volume curve.

Medical connector with lift tabs

A connector for coupling to a base of medical device equipped with a circular hub having a circumferential recess. The connector includes a cap having a top surface, a bottom surface, a central region, and a circumferential region.

Positioning the connector on the circular hub and pressing the connector engage the catches with the circumferential recess of the circular hub so the connector can rotate completely about the circular hub. Lifting at least one lift tab to reversibly displace the resilient lobe and its respective catch radially to disengage from the circumferential recess decouples the connector.

Tubular workpiece for producing an improved balloon cuff tracheostomy tube

There is provided a tubular workpiece for blow-molding into an inflatable balloon component. The tubular workpiece is a raw tube having a lumen and composed of a thermoplastic polymer, the tube having an asymmetric wall thickness such that when the tube is preheated in a mold to a temperature sufficient to soften the material of the tube and inflated with a gas to generally uniformly stretch the material of the tube, the tube forms a balloon component. The balloon may be non-uniform in wall thickness depending on the type of mold used. The balloon may be attached according to conventional means to a hollow tube to produce a tracheostomy device.

A method of making an improved balloon cuff tracheostomy tube

There is provided a method of making a balloon having a differential thickness. The method uses a raw tube composed of a thermoplastic polymer which is placed in an asymmetrical mold. The tube is preheated in the mold to a temperature sufficient to soften the material of the tube and inflated with a gas to generally uniformly stretch the material of the tube while allowing the tube to retract lengthwise, thus forming a balloon. The resulting completed balloon has a differential wall thickness wherein the upper region has a thickness of from about 15 to about 30 micrometers and the lower region has a thickness of from about 5 to about 15 micrometers.

Subglottic suctioning system.

Un sistema de succión subglótico con un tubo traqueal (10) que tiene un lumen de ventilación, un lumen de inflación de balón (14) y un lumen de succión (16) se describen, los cuales pueden ayudar a reducir la incidencia de la neumonía asociada con ventilador (o adquirida). El lumen de succión se comunica con el espacio en la tráquea arriba del balón (22) en donde las secreciones se acumulan. El lumen de succión tiene una válvula (36) en el extremo próximo para la conexión a una fuente de vacío. La válvula se adapta para interrumpir el suministro de vacío al lumen de succión para permitir la interrupción de un fluido de enjuague en su lugar y re-establecer automáticamente la conexión a la fuente de vacío al término del enjuagado. El fluido de enjuagado ayuda a mantener un lumen de succión abierta y puede incluir medicamentos y agentes mucolíticos para mejorar o promover la curación o para alterar las propiedades del moco para hacer más fácil la remoción. El usuario puede fácilmente y repetidamente alternar la succión y enjuagar el fluido a través del lumen de succión, es decir, el usuario puede "pulsar" la línea para aflojar, romper y remover las secreciones y depositar esas que pueden bloquear u obstruir completamente y parcialmente el lumen de succión.

Subglottic suctioning system

A subglottic suctioning system with a tracheal tube (10) having a ventilation lumen, a cuff inflation lumen (14), and a suction lumen (16) are disclosed which may help reduce the incidence of ventilator associated (or acquired) pneumonia.

The rinsing fluid aids in maintaining an open suction lumen and may include medicaments and mucolytic agents to enhance or promote healing or to alter the properties of the mucus to make removal easier. The user may easily and repeatedly alternate suction and rinsing fluid through the suction lumen, i.e., the user may "pulse" the line to loosen, break up and remove secretions and deposits that may partially or completely block or clog the suction lumen.

Rapid identification of organisms in bodily fluids

There is provided a lateral flow assay that can provide an indication of Gram negative (GN) or Gram positive (GP) infection (or both) within 30 minutes, and desirably in less than 15 minutes. The immediate result would signal the presence of Gram negative bacteria, Gram positive bacteria, both Gram negative and Gram positive bacteria, or no bacteria detected. The detection level would be above a specific bacterial concentration threshold that is clinically significant infection source (e.g. 10^3 cfu/ml) versus the presence of a colonizing bacteria that is not a part of the active infection.
