Means Or Method For Facilitating Removal Of Non Therapeutic Material From Body Patents (Class 604/540)
  • Patent number: 8814840
    Abstract: There is described a medical apparatus, which may comprise a fluid collection vessel and a sensor. The sensor is arranged to sense when the fluid collection vessel is substantially full even when the fluid collection vessel is tilted by up to a predetermined angle from its preferred orientation. The fluid collection vessel may comprise a main chamber and a sensor chamber in fluid communication with one another. The sensor is located in the sensor chamber. The fluid inlet, the main chamber and the sensor chamber are arranged such that fluid entering the fluid collection vessel via the fluid inlet flows into the main chamber even when the fluid collection vessel is tilted by up to the predetermined angle from its preferred orientation, and, once the main chamber is full, any further collected fluid flows from the main chamber into the sensor chamber.

  • Patent number: 8801698
    Abstract: A reservoir is incorporated in between a guide portion and an introducer tip of the introducer member. A spherical or similarly shaped plug is inserted into the guide portion. The plug is designed such that it forms a seal within the guide portion, preventing any fluid flow between the reservoir and an environment external to a distal end of the guide portion. This prevents a liquid or gel contained inside the reservoir from drying or leaking. The plug may further be held in place against a distal opening of the reservoir by positive pressure within the reservoir. The plug may further be held in place within the guide portion by a plurality of bumps or notches. When the catheter is advanced through the guide portion, the catheter tip pushes the plug into the reservoir, thereby breaking the seal and lubricating the catheter.

  • Patent number: 8795222
    Abstract: Topical exposure of nitric oxide gas to wounds such as chronic non-healing wounds may be beneficial in promoting healing of the wound and in preparing the wound bed for further treatment and recovery. Nitric oxide gas may be used, for example, to reduce the microbial infection and burden on these wounds, manage exudate secretion by reducing inflammation, upregulate expression of endogenous collagenase to locally debride the wound, and regulate the formation of collagen. High concentration of nitric oxide ranging from about 160 to 400 ppm may be used without inducing toxicity in the healthy cells around a wound site. Additionally, exposure to the high concentration for a first treatment period reduces the microbial burden and inflammation at the wound site and increase collagenase expression to debride necrotic tissue at the wound site.

  • Patent number: 8679079
    Abstract: A manually-activated reduced pressure treatment system includes a substantially rigid housing, and an end cap slidingly received by the housing. An inner chamber is disposed between the end cap and housing, and a volume of the inner chamber is variable in amount depending on the position of the end cap within the housing. The end cap is slidingly movable between an uncompressed position at which the volume of the inner chamber is at a maximum value and a compressed position at which the volume of the inner chamber is at a minimum value. A position indicating member is associated with the end cap and housing to indicate the position of the end cap relative to the housing at predetermined positions between the uncompressed position and the compressed position.

  • Patent number: 8668682
    Abstract: A vacuum regulator apparatus for continuous subglottic aspiration is provided. In one version, the regulator apparatus attaches to a standard vacuum regulator and shares the same vacuum supply outlet as the standard vacuum regulator. Sufficient airflow is provided through the regulator apparatus and calibrated bleed orifice to provide proper continuous subglottic aspiration. Vacuum levels to maintain the airflow are in a range suitable to provide patient comfort. A ball flow indicator provides visual indication of flow through a subglottic tube interface port of the regulator apparatus. A direct flow channel can be momentarily opened causing flow to bypass the regulator module in for clearing blockages affecting the subglottic tube interface port.

  • Patent number: 8663200
    Abstract: A negative pressure wound therapy apparatus can include a wound dressing, a fluid collection container, a vacuum pump comprising a pump motor, and tubing. Additionally, the apparatus can include a pressure sensor that measures a pressure in the tubing. One or more tubes can channel a fluid between the wound dressing, the fluid collection canister, and the pump. In addition, first and second control circuits can be provided for controlling the pump motor without using a processor. The first control circuit can generate a difference signal between a desired pressure input and a pressure sensor input, and can further generate a motor control signal responsive to the difference signal. Moreover, a second control circuit can provide an override signal based at least in part on the difference signal and at least one reference signal. The override signal beneficially overrides the motor control signal to prevent the pump motor from stalling.

  • Publication number: 20140046303
    Abstract: A method and device are provided for simultaneously or near-simultaneously diagnosing and treating tension pneumothorax and/or hemothoraxA Veress-type needle portion includes a hollow needle for puncturing the chest wall over a blunt hollow probe biased by one or more springs to extend distally into the pleural cavity. Openings in the blunt hollow probe connect via a pathway to an automatic check valve, which permits the flow of air and/or fluid only in a proximal direction. Pressure from within the pleural cavity is transmitted to the interior surface of a pressure documenter. If pressure greater than atmospheric pressure is present in the pleural cavity, the pressure documenter will be automatically urged proximally to simultaneously allow air and/or fluid to escape from the pleural space through the device, thus treating the tension pneumothorax and/or hemothorax, as well as providing a stable indicator to positively document the diagnosis of increased pressure.

  • Patent number: 8647327
    Abstract: The invention relates to a test unit for wound drainage coverings comprising: a base body with at least one cavity; at least one supply line that runs through the base body and which connects an outer side of the base body to the cavity; a surface of the base body that is embodied as a support surface for supporting wound coverings and the wound drainage coverings thereof and several channels that run through the base body, the channels connecting the cavities to the support surface. Low pressure can be produced in the cavity and the channels when the support surface is covered in an air-tight manner. As a result, wound drainage applications are tested in different ways using simple and economical means.

  • Patent number: 8636722
    Abstract: Various forms of anti-clog suction tips apparatus are disclosed. For example, an anti-clog suction tip apparatus includes a suction tip assembly having a suction tip with a suction opening at a first end thereof for removing debris through suction, a hose attachment portion for attaching the suction tip assembly to a suction source, and an ejection wire channel. The apparatus further includes an ejection wire assembly having an ejection wire extending within the channel and an ejection button integral with or connected to the ejection wire. Applying a force to the ejection button advances the ejection wire through the channel such that an end portion of the ejection wire enters the suction tip and dislodges debris clogging the suction tip. The ejection wire may include an enlarged end portion such as, for example a ball tip. One or more of the components of the apparatus may be single-use and disposable.

  • Patent number: 8636721
    Abstract: A manually operable pump for the effective removal of fluids to include blood, blood clots, fluid, and air from a body cavity of a subject is provided. The manually operable pump is adapted to be connect to a range of fluid conduits and is equipped with one-way valves that effectively permit flow of fluid through the pump in only one direction. The sensitivity of the one-way valves is such that when properly positioned, fluid can flow through the valves and out of the pump without manual compression of the pump and with the aid of gravity power alone.
