Definitions

  • the present technology includes processes and articles of manufacture that relate to a hyperangulated stylet, including a hyperangulated stylet with integrated suction.
  • a stylet can be a rigid but malleable introducer which fits inside an endotracheal (ET) tube and allows for manipulation of the tube shape to facilitate passage of the tube through the laryngeal inlet during tracheal intubation.
  • the stylet can provide additional rigidity to the ET tube which may aid in the placement of the ET tube.
  • a stylet can be preformed to match the shape of an angulated video laryngoscope and have a rigid design for fast intubation. When used with a video laryngoscope, the stylet can improve the view of the laryngoscope to enable fast and safe intubation.
  • suction may be necessary to clear secretions and to facilitate visualization in the airway for placement of the ET tube and to avoid introduction of airway debris further into the lungs or bronchial tree.
  • current suction technologies may not adequately clear the visual field during hyperangulated laryngoscopy. Adding suction to the blade of a laryngoscope may not reach a location deep enough in the visual field where proper suction can be achieved. Consequently, providing suction at the end of the laryngoscope blade may not properly clear the area. Further, providing suction at this location may block the view of the video laryngoscope.
  • suction is not always needed and may in certain instances be detrimental, a system in which suction can be selectively applied is desirable.
  • a hyperangulated stylet with integrated suction has a body including: a handle having a selectively coverable suction hole and a suction port, the suction port configured to connect to a suction source; and a stylet rod configured to be coupled to a lumen and having a distal end. Covering the suction hole enables suction through the lumen when the suction port is connected to the suction source.
  • a hyperangulated stylet with integrated suction includes a body.
  • the body includes a handle having a selectively coverable suction hole and a suction port.
  • the suction port can be configured to connect to a suction source to enable suction.
  • the body can also include a stylet rod having a distal end. A lumen that runs along an inside length of the stylet rod and extends out from the distal end of the stylet rod can provide suction for the hyperangulated stylet.
  • covering the suction hole enables suction through the lumen when the suction port is connected to the suction source.
  • a hyperangulated stylet with integrated suction includes a body.
  • the body can include a handle having a selectively coverable suction hole and a suction port.
  • the suction port is configured to connect to a suction source to enable suction.
  • the body can also include a stylet rod having a distal end. A lumen that runs along an outside length of the stylet rod and extends beyond the distal end of the stylet rod can provide suction for the hyperangulated stylet.
  • covering the suction hole enables suction through the lumen when the suction port is connected to the suction source.
  • a method of operating a hyperangulated stylet with integrated suction includes selectively covering a suction hole of the hyperangulated stylet to enable suction through a lumen of the hyperangulated stylet.
  • the lumen can run along an inside length of a stylet rod and extend out from a distal end of the stylet rod of the hyperangulated stylet.
  • the lumen can also run along an outside length of the stylet rod and extend beyond the distal end of the hyperangulated stylet.
  • FIGS. 1A, IB and 1C show a first embodiment of a hyperangulated stylet with integrated suction, in accordance with embodiments of the present disclosure.
  • FIGS. 2A, 2B and 2C show a second embodiment of a hyperangulated stylet with integrated suction, in accordance with embodiments of the present disclosure.
  • FIG. 3 shows a method of operating a hyperangulated stylet with integrated suction, in accordance with embodiments of the present disclosure.
  • Embodiments of the present disclosure advantageously provide a hyperangulated stylet with integrated suction.
  • the stylet has a body including a handle having a selectively coverable suction hole and a suction port that is configured to connect to a suction source and a stylet rod coupled to the handle and configured to be coupled to a lumen and having a distal end. Covering the suction hole enables suction through the lumen when the suction port is connected to the suction source.
  • the hyperangulated stylet may come with the lumen coupled to it or the stylet may not have a lumen, in which case the lumen will be either inserted into the stylet rod or coupled along an outside edge of the stylet rod, depending on the embodiment. The ability to change out the lumen allows for cleaning and replacement as needed.
  • a hyperangulated stylet with integrated suction and methodology for using the same is disclosed.
  • the hyperangulated stylet can include a relatively large internal diameter with an ability to connect to a suction source.
  • a lumen of a rigid hyperangulated stylet runs along an interior of the stylet in a relatively large internal diameter channel that accommodates the lumen.
  • a hole in the hyperangulated stylet handle can be a side-hole and can be selectively covered to enable suction through the lumen.
  • the lumen runs parallel (outside) to the stylet along an outside surface of the stylet rod, such as along an outside length of the stylet rod to enable in-line suction. In both cases, the lumen has a sufficiently large internal diameter and may have a particulate filter.
  • the hyperangulated stylet with integrated suction can be selectively operated by a person performing a procedure using the hyperangulated stylet.
  • the technology of the disclosure can provide certain benefits and advantages in a hyperangulated stylet.
  • the hyperangulated stylet of the present disclosure can enable selectively appliable suction and utilizes a lumen for suction that extends past a distal end of a stylet to enable suction without injuring the patient.
  • the hyperangulated stylet can be complementary shaped to a video laryngoscope to enable fast and safe intubation.
  • the hyperangulated stylet with integrated suction of the present disclosure enables suction during intubation while still being able to visualize the area with the video laryngoscope.

Abstract

Stylet hyperangulaire à aspiration intégrée pouvant comprendre un corps. Le corps peut comprendre une poignée ayant un trou d'aspiration pouvant être sélectivement recouvert et un orifice d'aspiration, une tige de stylet et une pointe dorsale. Le port d'aspiration peut être conçu pour se connecter à un dispositif d'aspiration. Une lumière du stylet hyperangulaire avec une aspiration intégrée peut s'étendre le long d'une longueur intérieure de la tige de stylet et s'étendre hors de la pointe dorsale. En variante, la lumière peut s'étendre le long d'une longueur extérieure de la tige de stylet et s'étendre au-delà de la pointe dorsale. Le recouvrement du trou d'aspiration peut permettre une aspiration à travers la lumière lorsque le port d'aspiration est connecté au dispositif d'aspiration.
