AI Technical Summary

Benefits of technology

The present invention provides a laryngo-tracheal anesthetic device that can be used during intubation procedures. The device has a reversibly deformable conduit that can be bent and maintained in shape to guide an ETT. The device can also function as an introducer for placing the ETT. The device is designed to be easily assembled, replaced, or sterilized without needing to replace the entire device. The invention also provides a method to decrease the total time involved in performing a direct laryngoscopy by combining the functions of anesthetizing the patient's trachea and posterior pharynx and also as a stylet and introducer for placing an ETT. The invention is modular in design, allowing for easy assembly, replacement, or sterilization of components. The invention also provides a device for pressurizing a cartridge of anesthetic on an intravenous line.

Problems solved by technology

These two or more discreet steps potentially distract the anesthetist who must first reach for the LTA device and then the ETT.
Also, the act of direct laryngoscopy places a great deal of stress on the patient.
Many patients, such as those with heart disease, do not tolerate these large swings in blood pressure and in heart rate which can occur with multiple acts of direct laryngoscopy.
Additionally, prolonged direct laryngoscopy creates increased risks for the patient.
Prolonging direct laryngoscopy causes increased edema, tissue trauma, bleeding, and secretions, which all impair the view of the vocal cords by the time the ETT is to be placed.
During this time period, the trachea is unprotected and the risk of aspiration is increased.
Also, on occasion the stimulation caused by LTA placement in an incompletely paralyzed patient may cause reflexive spasm of the vocal cords, thus preventing placement of the ETT altogether.
Often a “top heavy” intubation device, when loaded into an endotracheal tube inadvertently causes trauma to the eyes and face of the patient during manipulation of the device.
However, these devices require extreme dexterity as the anesthesiologist must change hand positions multiple times to inject the LTA and place the ETT.
Changing hand positions is further complicated because the anesthesiologist must dedicate one hand to holding the laryngoscope blade.
In fact, the greatest challenge of such a combined stylet and LTA device is to be able to perform the intended function of LTA application without increasing the current level of difficulty, dexterity, and skill needed to administer the LTA, all without increase movement of the device in situ.

vial embodiment

[0053]Though the following discussion of the dispenser relates to a laryngo-tracheal anesthetic device that can also serve as an aid during intubation, the dispenser can be used for a variety of other purposes. For instance, the dispenser can be part of a stand-alone LTA device that can be passed through an ETT, including a pediatric ETT, or an LTA over which an ETT is passed. Additionally, the dispenser, as discussed below, can be used for administering a controlled dose of a medicament through an IV, and it allows for the easier performance of a nerve block procedure. In short, the dispenser portion of the device can be used for a variety of applications and in a variety of contexts.

[0054]The dispenser 15 comes in a variety of embodiments. In each embodiment, the dispenser 15 is adapted to receive a cartridge or ampule of anesthetic. The dispenser 15 releases the contents of the cartridge for dispersion through the conduit 20 and out the nozzle 25 when actuated by the actuation me...

Syringe Embodiment

[0078]In a second embodiment of the present invention depicted in FIGS. 8A-8D, the dispenser 15 works in combination with a syringe 102. In some configurations of the second embodiment, a reservoir 100 is utilized to pressurize the fluid in the syringe 102. In other configurations, the syringe 102 is pressurized, either internally or externally, and connected directly to a pressure release valve 104 (as shown in FIG. 8A).

[0079]In configurations using a reservoir 100, the reservoir 100 is adapted to receive the syringe of anesthetic as depicted in FIG. 8A such that the reservoir is positioned between the syringe and the stylet 20. The reservoir defines a cavity which is isolated from the ambient environment. The syringe 102 is a typical one in that it comprises a barrel 105, a plunger 110 slidably received by one end of the barrel, and a tip 115 positioned at a second end of the barrel. Some syringe embodiments also feature finger tabs 117, which provide a means to ...

Abstract

A nozzle received by a patient. The nozzle has at least two portions. A first portion that has an upper end and a lower end in which a central aperture extends between the upper and lower ends of the nozzle. The central aperture terminates at the opening of the lower end of the nozzle. A second portion that has two ends, the second end is rounded. There is at least one support arm joining the first and second body portions but holding the second body portion a set distance from the first body portion.

Description

PRIORITY[0001]This PCT application claims the benefit of U.S. patent application Ser. No. 14 / 301,170, filed on Jun. 10, 2014, the entirety of which is incorporated by reference.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The present invention relates to a method and device for anesthetizing and intubating, and more particularly, the present invention relates to a method and device for anesthetizing and intubating a patient with a single hand movement.2. Background of the Invention[0003]Laryngo-tracheal anesthesia (LTA) is an important component of the anesthetic plan for general anesthesia during surgery. LTA blunts airway reflexes and discomfort involved in the manipulation of the airway for surgery and facilitates placement and maintenance of an endotracheal tube (ETT). Of the approximately 15 million general anesthetic procedures performed each year that require an ETT, about one third will require the use of LTA.[0004]Often laryngo-tracheal anesthetic is applied ju...
