摘要:
A subglottic suctioning system with a tracheal tube having a ventilation lumen, a cuff inflation lumen, and a suction lumen are disclosed which may help reduce the incidence of ventilator associated (or acquired) pneumonia. The suction lumen communicates with the space in the trachea above the cuff where secretions accumulate. The suction lumen has a valve on the proximal end for connection to a source of vacuum. The valve is adapted to interrupt the supply of vacuum to the suction lumen to allow for the introduction of a rinsing fluid in its place and to automatically re-establish the connection to the source of vacuum upon completion of rinsing. 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.

摘要:
There is provided a tracheal catheter designed so that a suction catheter may be used to suction out any secretions that accumulate in the zone above the balloon. There is further provided a tracheal catheter having a ventilation lumen with a flexible wall to provide a flexible lumen which takes up negligible volume when the catheter is not inserted. The suction catheter may be inserted into the flexible lumen, bending the flexible lumen wall that normally lies substantially flat against the ventilating lumen. As the suction catheter is inserted into the lumen, the lumen opens to accept it. When the catheter is removed, the wall of the flexible lumen moves back into position against the ventilating lumen wall, again taking up negligible volume. There is also provided a method of suctioning the subglottic space of an intubated patient. This involves providing a tube as described above, inserting a catheter into the flexible lumen from the proximal end, and providing suction to the proximal end of the catheter.

There is provided a device that retains a collected sample for on-demand testing of a small portion of the collected sample while the rest of the sample remains for optional additional analysis. The on-demand test provides relatively immediate information about aspects of the sample, e.g. presence of microbes, chemistry, nutritional condition, presence of contaminants.

There is provided a device for sampling bodily fluids. Some embodiments have a handle, a lumen, and a diverter valve. The distal end of the handle is adapted to connect with a sampling device and is in fluid communication with the lumen. There is a vacuum connection on the proximal end of the handle that is also in fluid communication with the lumen. A suction valve may desirably be located in the lumen to control the application of vacuum from the vacuum connection to the sampling device. The diverter valve directs the flow through the lumen such that a sample from the patient goes into a sputum trap when the trap is connected. The device may further have a saline port in fluid communication with the lumen, located distal to the suction valve, for rinsing the tube and diluting secretions.

There is provided a device for performing a balloon dilation tracheostomy. The balloon has internal braces or “stays” extending from the center to the inside surface of the balloon, though other arrangements are possible. The braces control the ultimate expansion and final shape of the balloon when it is fully inflated, inhibiting the ability of parts of the balloon to herniate. The balloon should also expand more uniformly, allowing the practitioner to more confidently expand the tracheal stoma site and ensuring a successful dilation and tube placement.

An oral care suction device that includes a suction control port cover. The oral care suction device includes a body having a fluid flow passage formed therethrough. The body has a suctioning feature is located on or joined at its distal end. The body also has an attachment feature located at its proximal end. The oral care suction device also includes a suction control port located intermediate the distal end and proximal end of the body and configured to be covered by a finger or a portion of the hand of a user to alter the level of suction through the suctioning feature while allowing one hand operation of the suctioning device. The suction control port defines a channel from an exterior of the body to the fluid flow passage. A breathable fabric is positioned to cover the suction control port so that contact of the finger or portion of the hand of a user with liquids and particles drawn into and through the fluid flow passage during suctioning is minimized.

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 medical device assembly for imparting a lubricious and/or antimicrobial liquid onto a medical device is provided. The medical device is surrounded by a pouch and includes a burst package or frangible cells for storage of the liquid prior to delivery onto the surface of the medical device. This helps prevent contamination of the medical device upon removal of the medical device from its pouch, insertion of the device into a body cavity, and implantation of the device into the body cavity.
