  • 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: 10569039
    Abstract: An introducer for tracheal tube intubation has a proximal section connected to a distal section having an angled bougie tip. The introducer is configurable (i) for use as a bougie in which a tracheal tube is railroaded over the introducer's back end and into a trachea and (ii) for use as a stylet in which a tracheal tube is pre-loaded onto the introducer for insertion into a trachea. In certain embodiments, the introducer has one or more flexible or malleable sections that enable the introducer to bend into different configurations. The flexible/malleable sections have directional bending such that the sections bend in roughly the same plane as the angled bougie tip. This enables an operator always to know the orientation of the bougie tip even after it has been inserted into the trachea. The flexible/malleable sections enable the introducer to be configured with a handle or other type of grip.

  • Patent number: 10524651
    Abstract: A laryngoscope insertion section for a laryngoscope, which is typically a video laryngoscope, includes a lateral tube guide configured to retain an endotracheal tube in a plane. A viewing port for a camera or other image collector is laterally displaced from the plane of the endotracheal tube. The said plane of the endotracheal tube is aligned substantially in the same plane as a patient's median plane and the tube can be advanced into the larynx using a natural curving motion similar to the motion used to introduce an endotracheal tube using a convention laryngoscope. In a preferred embodiment, the distal tip of the insertion section and a retained endotracheal tube will be located in the patient's median plane during intubation. As the tube guide retains endotracheal tubes substantially in a plane, lateral curvature is avoided, reducing resistance to advancement of the tube.

  • Patent number: 10328227
    Abstract: A tracheal tube includes an inner cannula and an outer cannula that are connected with a threaded connection able to swivel, and wherein the inner cannula is also connected to an elbow adaptor through a Bayonet Neill-Concelman (BNC) connection. Both the threaded and the BNC connects provide more secure connections of the corresponding components and are able to withstand greater amounts of force exerted on them without becoming detached from each other. The elbow adapter may further be coupled to a pressure release valve that will alleviate pressure buildup within the tracheal tube.

  • Patent number: 10314516
    Abstract: A method of diagnosing an air leak in a lung compartment of a patient may include: advancing a diagnostic catheter into an airway leading to the lung compartment; inflating an occluding member on the catheter to form a seal with a wall of the airway and thus isolate the lung compartment; measuring air pressure within the lung compartment during multiple breaths, using the diagnostic catheter; displaying the measured air pressure as an air pressure value on a console coupled with the diagnostic catheter; and determining whether an air leak is present in the lung compartment based on the displayed air pressure value during the multiple breaths.

  • Patent number: 10314993
    Abstract: A laryngeal mask (1) comprising an air-way tube (2) and a mask portion (6) with an inflatable cuff (8) which is arranged around the airway tube (2) at the distal end thereof. A gastric tube (12) which extends at least partially along the outer surface of the airway tube (2), penetrates through the wall of said inflatable cuff (8) at a first location, extends through said inflatable cuff (8), and ends in a connection to an opening (12) in the wall of the cuff at a second location at the tip part of the laryngeal mask, so as to provide a passage through said circumferential cuff. With respect to a central mirror symmetry plane said gastric tube extends along the outer surface of the airway tube (2) in an asymmetrical manner, through said inflatable cuff (8) at the first location arranged asymmetrically with respect to said central plane, through said inflatable cuff (8), and ends in the connection to the wall of the cuff (8) at the second location at the tip part.

  • Patent number: 10279145
    Abstract: A single-use, sterile, disposable catheter placement assist device to aid in the sterile placement of transurethral urinary catheters in female patients, and a method for catheter placement using the device. The catheter placement assist device includes a labia separator with flared wings having a curved profile. The wings meet at a valley. The catheter placement assist device also includes a posterior shield that covers the perineal tissues including the anus to prevent contamination of the sterile catheter with bacteria and may further include a spout that may be shallowly inserted into the vagina to position the catheter device to optimize labial separation, retraction of the posterior vaginal wall, perineal shielding, and visualization of the urethral meatus. The additional features of a light, a handle, a catheter tip holder, a swab storage location, and a stackable configuration may further be included with the catheter placement assist device.

  • Patent number: 10258319
    Abstract: An airway assist device (AAD) is provided. The device includes an upper AAD component and a lower AAD component. The upper AAD component includes and upper tooth guide connected to an upper plate having a pair of depending legs. The upper AAD component further includes an upper force receiving plate. The AAD also includes a lower AAD component. The lower AAD component includes a lower tooth guide connected to a lower plate. The lower AAD component further includes a lower force receiving plate. The upper and lower AAD components are connected in a way that allows relative longitudinal movement between the two components between a neutral position and a plurality of extended positions. A ratchet mechanism inhibits movement of the lower plate from any extended position toward the neutral position. The ratchet mechanism may be manually disengaged to allow the lower AAD component to return to the neutral position. An oxygen delivery housing may be connected to the upper plate to distribute oxygen.

  • Patent number: 10251533
    Abstract: The outer tube includes two insertion holes which are formed in a cross-sectional D-shape via a partition wall provided in the central part in a cross-section vertical to respective axial directions of the insertion holes. A slit of a valve body located in the insertion hole is disposed along reference line passing through centers of respective arcs of the insertion holes as seen from the axial directions of the insertion holes. Therefore, two leaflets of the slit abut on an arc edge of the insertion hole and a D-shaped cut part of the partition wall respectively when the insertion part of the treatment tool is internally fitted, and they are deformed into the same shape. Since there is no difference in stress applied to two leaflets, it is possible to secure the airtightness by the slit over a long period of time.
