  • Patent number: 10272175
    Abstract: There is provided a composition comprising covalently linked segments of for example, polycaprolactone and polyethylene glycol that are linked by a cross-linker. Such a composition foams in the presence of a catalyst and a solution containing an oxygen forming chemical like hydrogen peroxide. The foamed composition retains oxygen for delivery to, for example, a wound, where it aids in healing.

  • Patent number: 10245401
    Abstract: 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.

  • Publication number: 20180161476
    Abstract: The present disclosure is directed to a closed cell foam matrix for delivering oxygen containing a superabsorbent material oxygen entrapped within the superabsorbent material. The superabsorbent material has at least 15 percent by mass monoethylenically unsaturated carboxylic, sulphonic or phosphoric acid or salts thereof, an acrylate or methacrylate ester that contains an alkoxysilane functionality, and a copolymerizable hydrophilic glycol containing ester monomer. To produce the closed cell foam matrix for delivering oxygen, an alkali hydroxide catalyst is added to the superabsorbent material to form a hydrogel layer. Then, an oxygen precursor is added to the hydrogel layer. The hydrogel layer is heated to produce oxygen by reacting the alkali hydroxide catalyst and the oxygen precursor thereby entrapping the oxygen in the formed closed cell foam matrix.

  • Patent number: 8974399
    Abstract: 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.

  • Patent number: 8607795
    Abstract: There is provided a balloon cuffed tracheostomy tube with a balloon designed so as to enhance the tube's anchorability without sealing the tracheal stoma. The tracheostomy tube device includes a conventional curved hollow tube. The distal end of the tube is adapted for insertion through a tracheal stoma and into the tracheal lumen of a patient's throat. The device further includes an inflatable balloon enveloping a portion of the tube. The balloon has a distal portion substantially centered about and attached to the distal end portion of the tube. The balloon also has a proximal portion attached to the bend region of the tube and positioned substantially off-center relative to the proximal portion of the tube and about the bend region below the proximal plane of the device.

  • Patent number: 8545951
    Abstract: Anti-fouling treatments are applied to polymer substrates for preventing bacterial adhesion. The polymer substrate may comprise a medical device, such as a catheter. The treatment generally comprises a polymer layer graft polymerized to the surface of the polymer substrate. An anti-biofilm agent is contained in the polymer layer or applied to the surface. A polymer over-layer is then applied that encapsulates the anti-biofilm agent. The anti-biofilm agent prevents bacterial adhesion through the polymer over-layer.

  • Patent number: 8307824
    Abstract: There is provided a method for performing a tracheotomy. In this method a tracheostomy dilator has a body and a tip which are detachably attached. The tip has a proximal inner portion which is within the body while the tip is attached to the body. The dilator is inserted into the trachea and used to dilate an opening. After the trachea has been dilated, the body may be detached and removed from the tip, the tip remaining partially in the trachea. A dilator loading catheter installed within a tracheostomy tube may be mated with the tip and the tip, loading catheter and tracheostomy tube moved into the trachea. After the tracheostomy tube is installed, the tip and loading catheter may be withdrawn through the tracheostomy tube and the tracheostomy tube placed in service.

  • Publication number: 20110290245
    Abstract: 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.

  • Publication number: 20110159456
    Abstract: 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.

  • Patent number: 7913640
    Abstract: There is provided a moisture indicator for a heat and moisture exchange (HME) device that uses a pre-colorant and an activator applied to an inner surface of the HME device. The colorant undergoes a color change of Delta E (?E) of equal to or greater than 3 units upon exposure to moisture but not upon exposure to high humidity. The colorant is visually obvious to the unaided human eye under normal light conditions through the body of the device. The HME device with the visual indicator for moisture can indicate to the care-giver that it is time to change the HME device.

  • Publication number: 20100147309
    Abstract: 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.
