  • Patent number: 11395873
    Abstract: Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In one embodiment, a negative pressure source can provide negative pressure via a fluid flow path to a wound dressing comprising a stabilizing structure. The stabilizing structure can be inserted into a wound and collapse upon application of negative pressure to the wound when the stabilizing structure is positioned in the wound. A controller can in turn determine a measure of collapse of the stabilizing structure from a pressure in the fluid flow path while the negative pressure source maintains a magnitude of the pressure in the fluid flow path within a negative pressure range. The controller can output an indication responsive to the measure of collapse.

    Abstract: Apparatus for transporting particles through a patient's trachea into the respiratory system include a delivery tube having at least a ventilation lumen and a particle delivery lumen. The delivery tube has a centering device near its distal tip, such as a balloon eccentrically mounted on the tube to position an outlet of the particle delivery lumen near a centerline of the trachea above the carina branching into the right and left bronchus. A proximal end of the delivery tube connects to a source of particles, and a controller may be provided to adjust a rate and/or an amount of the particles delivered to the patient. In a specific example, frozen particles are delivered to control core body temperature. In other instances, the particle may be a medicament or other substance for effecting other therapies or diagnostic procedures.

  • Patent number: 10758114
    Abstract: Disclosed is a laryngoscope insertion section having a curved superior surface and a curved inferior surface, and a channel extending from the proximal end the channel having an inferior internal surface with a greater curvature than the curvature of the inferior surface. The insertion section is compatible with laryngoscope hardware optimised for indirect viewing, yet enables direct viewing. Additionally, the distance between the inferior and superior surfaces is at a maximum within the intermediate portion, and enables the dimensions of the proximal and distal portions to be minimized. Thus, the intermediate portion, which is located in the patient's oral cavity in use, is provided with greatest depth and therefore strength where the greatest forces are received, whereas the distal and proximal portions are of reduced dimensions to as to minimize trauma to the patient's airway and mouth areas, respectively, in use.

  • Patent number: 10716910
    Abstract: A resuscitator mouth shield assembly for protecting a caregiver from bodily fluids during CPR includes a resuscitation bag that has a hose extending toward a face cup. A coupler releasably engages the resuscitation bag and a panel is rotatably coupled to the coupler. The panel is spaced from the resuscitation bag when the coupler is positioned on the resuscitation bag. Moreover, the panel is positioned between a patient's face and a caregiver when the resuscitation bag is positioned on the user's face. In this way the panel inhibits bodily fluids that are expelled from the patient from contacting the caregiver.

  • Patent number: 10709858
    Abstract: The present invention is a multipurpose airway device adapted for insertion into the mouth of a patient. The airway device has an elongate, tubular airway body of substantially elliptical or substantially circular cross-section with a substantially straight section, the proximal end of which is adapted to function as an integral bite block; a curved distal section with a distal tip; and a central channel for accepting an intubation device. The airway device further includes a substantially oval-shaped detachable intraoral seal and a connector for facilitating attachment of breathing or anaesthesia equipment thereto. The invention also relates to an ETT locking device for attachment to the multipurpose airway device and a multipurpose airway pack including the multipurpose airway device and the ETT locking device.

  • Patent number: 10653510
    Abstract: An example medical device for treating a body lumen is disclosed. The medical device includes an expandable scaffold positionable within a body lumen wherein the body lumen has an inner surface. The medical device also includes a support member extending circumferentially around and attached to an outer surface of the expandable scaffold. The support member is configured to be positioned between the outer surface of the expandable scaffold and the inner surface of the body lumen and at least a portion of the support member is configured to shift relative to the inner surface of the body lumen. Further, shifting the support member shifts the scaffold longitudinally from a first position within the body lumen to a second position within the body lumen with the scaffold in an expanded state to accommodate peristalsis.

  • Patent number: 10610655
    Abstract: Systems and methods are provided for inserting an endoscope through an anatomical cavity to a target site. A speaker is positioned externally proximate to a patient and the endoscope is inserted into the anatomical cavity. A signal is received from at least one sensor positioned near the distal end of the endoscope. The signal is indicative of vibrations induced in internal cavity tissue by the externally positioned speaker. A first anatomical structure in contact with the distal end of the endoscope is identified based on the signal indicative of vibrations induced in the internal cavity tissue by the externally positioned speaker. As the distal end of the endoscope moves from the first anatomical structure into contact with other anatomical structures along a path to the target site, the received signal indicative of induced vibrations changes correspondingly and is used to guide the endoscope to the target site.

  • Patent number: 10603454
    Abstract: A tracheostomy tube assembly comprises an outer tracheostomy tube (1) and an inner cannula (20) fitted in the tube. The machine end of the inner cannula has a collapsible region (22) formed by a plurality of curved or bent struts (26) extending parallel with one another between a machine end collar (28) and a patient end collar (27). The struts (26) carry outwardly-projecting catches (23) arranged to engage a rib (24) extending around the inside of a hub (16) at the machine end of the tube and thereby resist removal of the cannula from the tube. The inner cannula (20) is removed by twisting the machine end collar (28) so that the struts (26) collapse inwardly and thereby disengage the catches (23) from the rib (24).
