  • Patent number: 10610670
    Abstract: Provided is a catheter fixture. The catheter fixture includes: a base plate having a base hole for passing a catheter; and a fixture body formed on a top of the base plate, and the fixture body having a first guide hole connected to the base hole, extending in an open direction of the base hole, and guiding the catheter and a second guide hole extending in a different direction from the first guide hole and guiding the catheter. Since the first guide hole and the second guide hole are formed in different directions in the catheter fixture, a user can extend the catheter in different directions if necessary. Accordingly, it is possible to more stably and simply prevent backflow of food or medicine, using one catheter fixture without a specific component.

  • Patent number: 10603455
    Abstract: A tracheostomy tube (1) has a movable and lockable flange (2) by which the tube can be supported about the neck of a patient. The flange has a rotatable locking ring (34), which is threaded with a housing (26) fixed with the wings (22 and 23) of the flange. A resilient sleeve (50) is located in a recess (44) of the locking ring between a compression surface (45) on the locking ring at one end and the floor (46) of the housing at the opposite end. When the locking ring (34) is twisted it is moved forwardly along the housing (26), thereby compressing the resilient sleeve (50) axially. The axial compression causes the sleeve (50) to expand radially against the outside of the tube (1) and the inside of the housing (26), thereby locking the flange (2) in position.

    Abstract: Systems and methods for respiratory therapy are disclosed. The system may include a nebulizer, an adaptor, and a nasal cannula. The nebulizer is operable to generate an aerosolized medicament and pass the aerosolized medicament through a nebulizer outlet port. The adaptor has a nebulizer coupling port configured to be coupled to the nebulizer outlet port. The nasal cannula is configured to provide a flow of breathing gas from a breathing gas source to the patient. The nasal cannula comprises at least one nasal prong and an attachment device positioned adjacent the at least one nasal prong. The attachment device is configured to secure the adaptor outlet port adjacent an outlet of the nasal prong. The method includes securing a nasal cannula to the patient, attaching an adaptor to the nasal cannula, generating an aerosolized medicament, transferring the aerosolized medicament into the adaptor, and providing a flow of breathing gas to the patient.

  • Patent number: 10219686
    Abstract: An integrated medical bite block is engaged by a user's teeth and installed into the user's mouth. The bite block includes a through passageway, an upper grove, and a lower grove. The through passageway is penetrating through the bite block. One end of the through passageway comprises an inlet opening, the other end comprises an oral opening. The oral opening is connected with the user's mouth. An upper surface of the bite block provides the upper grove configured for receiving one or more upper teeth (maxillary teeth) of the user, and a lower surface of the bite block provides a lower grove configured for receiving one or more lower teeth (mandibular teeth) of the user. One distance between the lower grove and the oral opening is greater than the other distance between the upper grove and the oral opening, thereby the invention serves to extend forward the mandible and reposition a malposition between the mandible and the maxilla of the user.

  • Patent number: 10213568
    Abstract: A nasopharyngeal cannula comprising a body formed by a tubular portion that is curved so as to be inserted into a patient's nostril and a collar for resting on the base of the patient's nostril is described. The cannula also comprises a main channel forming a fluid passage between the collar and the tubular portion of the body and two auxiliary channels formed in the body and extending from the collar into the main channel. Each auxiliary channel opens into the collar at an inlet/outlet port oriented radially in relation to the axis of the main channel such as to be oriented laterally on each side of the patient's nostril when the cannula is in place on the patient.

  • Patent number: 10213567
    Abstract: Supraglottic airway devices such as the laryngeal mask airway (LMA) device are used in anesthesia practice to maintain an open airway in patients undergoing anesthesia. LMA devices are also used as a conduit for the insertion of endotracheal tubes (ETT) through the laryngeal opening into the patient's trachea (endotracheal intubation). In scenarios where the conventional method of tracheal intubation is challenging or not possible, modified LMA devices have played a pivotal role for several decades. However, present embodiments of LMA devices suffer from significant shortcomings that the device in this patent aims to address. Currently available modified LMA devices have many limitations when used as a conduit for the insertion of ETT. The apparatus shown the present description aims to address those major limitations and to significantly improve the success rate of tracheal intubation.

  • Patent number: 10213224
    Abstract: A cleaning device for cleaning a catheter lumen of a tissue removal catheter has a flushing chamber with distal and proximal seals and an inlet port. The proximal seal is a duckbill seal that includes a pair of opposing duckbill members that slidingly accept the distal end portion of a catheter body to form a seal about the catheter body proximal to a proximal opening in of the catheter lumen. Fluid is directed in the inlet port, into the flushing chamber, into proximal opening in the catheter body, and through the catheter lumen to discharge tissue contained in the catheter lumen. In some embodiments, the cleaning device is preloaded on the catheter body. The cleaning device can have an internal stop that engages with an external stop on the catheter body when the cleaning device is positioned in an operative position.

  • Patent number: 10201694
    Abstract: A medical catheter control valve includes a valve body defining a fluid channel and a single open-end hole extended across the fluid channel, and a click-on mechanism consisting of a plunger unit with a through hole and a spring member and mounted in the single open-end hole. When click the plunger unit, the plunger unit is shifted to keep the through hole in alignment with the fluid channel for allowing a fluid to pass through the fluid channel. When push back the plunger unit, the through hole is deviated from the fluid channel and the fluid channel is blocked. Thus, the medical catheter control valve can be conveniently controlled with one single hand.

  • Patent number: 10173023
    Abstract: An oropharyngeal device is disclosed for insertion into the oral cavity and the oropharynx of an individual. The oropharyngeal device comprises a tubular member extending between a proximal end and a distal end. The tubular member includes a channel extending between the primary aperture and the secondary aperture. A flange is coupled to the proximal end of the tubular member. The tubular member defines a gradual narrowing of the tubular member between the proximal end and the distal end for avoiding gagging reflex of the individual upon insertion of the distal end of the tubular member through the oral cavity and positioned adjacent to the epiglottis. The tubular member defines an arcuate shape for depressing the tongue and maintaining airway patency between the oral cavity and the epiglottis.

  • Patent number: 10149956
    Abstract: A bi-lateral endobronchial suctioning device includes actuating and articulating components that allow a provider to accurately suction both right and left bronchi as well as the trachea in a controlled and safe manner. A control mechanism is used to manipulate the actuating components in tubes forming a suction catheter to flex the tip of the bi-lateral endobronchial suctioning device to the left and to the right when the device is inserted through an endotracheal tube or other similar device, to enable directional control of a catheter for suctioning the lungs or trachea. The device further includes a bronchoalveolar lavage (BAL) port allowing sterile saline or other liquids or fluids to travel down the catheter lumen to assist with breaking up thick secretions which collect in the airways.
