BACKGROUND OF THE INVENTION
The present invention relates to medical training devices and, more particularly, a wearable airway medical training device.
When conducting airway-related medical training, emergency medical personnel face the challenge of learning their trade using unrealistic and bulky wearable surgical airway training devices. Simply put, current surgical airway training devices are too large, thereby creating an inaccurate appearance of the neck, resulting in an unrealistic experience, and thereby inculcating the medical personal being trained in surgical airway procedures with an impracticable simulation. Additionally, the reset time for current surgical airway training devices is not conducive to training a large number of students.
As can be seen, there is a need for a wearable medical training device that provides a realistic airway-related training simulation as well as capable of being quickly reset.
The device embodied in the present invention allows a role player to more accurately simulate a patient with an airway obstruction, and thereby more constructively teach related surgical airway procedures, while maintaining realism for the trainee and safety for the wearer. The present invention allows for safe and realistic surgical airway training through providing a wearable airway medical training device with the lowest possible profile, thereby facilitating a realistic simulation by the role player in movement and appearance. Additionally, the airway medical training devise embodied by the present invention enables rapid resetting of the device for a fast-paced training environment.

DETAILED DESCRIPTION OF THE INVENTION
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Broadly, the present invention embodies a two-piece airway-related medical training system composed of a base plate and a front panel. The base plate is secured around the neck of a role-playing wearer and has an integrated cut-resistant layer. The front panel connects over the base plate of the wearer. The front panel provides a trachea portion having a replaceable cuttable skin portion to facilitate the airway-related medical training. The front portion may also provide a fluidly coupled blood simulator, a simulated wound site, and other indicia of neck injuries that are used to teach and educate trainees of the airway-related medical training system.
Referring now to FIGS. 1 through 7C, the present invention may include a base plate 1 and a front plate 6 adapted to work in concert to provide a wearable, safe, low-profile device for training airway-related surgical procedures. The base plate 1 and the front plate 6 may be 1/16th to 3/16th inch in thickness, or in other words the combined being the thickness of the base plate thickness and the front plate thickness, wherein the combined thickness is between and including 1⁄8th of an inch to 3⁄8th of an inch. The base plate 1 may encompass a flexible steel mesh 2 or have the flexible steel mesh 2 embedded therein or otherwise integrated thereto. The flexible steel mesh 2 may be replaced with any flexible, durable, cut-resistant layer, like Kevlar or a blend of Kevlar and steel or a composite of like materials.
The base plate 1 may be anvil-shaped with a body portion 20, a waist portion 22, a heel portion 24, and a horn portion 26, as illustrated on FIGS. 1 and 2. The body portion 20 may provide a mesh window or boundary 30 on one or both surfaces thereof to provide visibility of the integrated steel mesh 2 or an indication where a central/body portion 10 is during use. The heel portion 24 may provide a first connector 4 and second connector 5 on opposing, front and rear surfaces, respectively.
The hook portion 25 and the heel portion 24 may be dimensioned and adapted to wrap around a human neck so that the first connector 4 can removable connect to the second connector 5 in a secured condition, securing the body portion 20 adjacent to a trachea area of the wearer. The first connector 4 is more elongated than the second connector 5 so that a proximal portion of the first connector 4 would be unengaged by the second connector 5 in the secured condition. A third connector 3 may be disposed between the body portion 20 and a distal end of the horn portion 26. As a result, in the secured condition, the proximal portion of the first connector 4 and the third connector 3 are viable to be attached to by the front panel 6. The removable connectors 3, 4 and 5 may be hook and loop fasteners or the like for adjusting the fit to different-sized necks.
The waist portion 22 may be a flap dimensioned and adapted to protect against irritation of the role player/wearer while an airway tube or adjunct tools are utilized/inserted during the airway-related training.
The front panel 6 may be a sleeve with an access window 40 that communicates between a front surface and opposing rear surface of the front panel 6. The access window 40 is centrally located. The front panel 6 provides rear connectors 7 along the both ends thereof. The rear connectors 7 are dimensioned and adapted to engage the proximal portion of the first connector 4 and the third connector 3 of the base plate 1 in the secured condition, removably attaching the front panel 6 to the base plate 1 in such a way that the access window 40 lays over the integrated steel mesh 2 defined by the cutout 30 or at least boundary defined by 30. In any event, the access window 40 is adjacent to and/or surrounds the trachea of the role player.
A sacrificial skin component 17 may be dimensioned and adapted to removably cover the access window 40. In other embodiments, the sacrificial skin component 17 may be sandwiched between the base plate 1 and the front panel 6 so as to be engaged by the front panel 6 so that a portion of the sacrificial skin component 17 is visible through the access window 40, creating a realistic simulation of airway-related/trachea skin while allowing for rapid replacement of the sacrificial skin component 17 after a trainee is done performing surgical access. The sacrificial skin component 17 may be designed to be cuttable by surgical tools to access other portions of the sleeve-like front panel 6, which represents other portions of the role player's neck. Thereby the airway-related medical training enables a trainee access to the “neck” of the role player without damaging reusable (non-sacrificial skin component 17) parts of the front panel 6. The front panel 6 may have a simulated wound 13 fluidly coupled to a conduit 14, a pump system 16 and a blood reservoir 15 for creating the appearance of an arterial bleeding from the simulated wound site 13.
The front panel 6 and/or the sacrificial skin component 17 may come in various colors and textures, as exhibited in the illustrations, specifically skin colors and textures of 8, 9 and 10, whereby the front panel 6 provides, for instance, textured skin to give the appearance of burns to the entire surface front surface.
The sacrificial skin component 17 may also be fluidly attached to the blood reservoir 15 for creating the appearance of bleeding from the trachea area. The blood pouch 15 may be placed behind the sacrificial skin component 17 and filled with simulated blood to give the appearance of bleeding from the surgical site when the users cuts through the sacrificial skin component 17.
The present invention allows the end user to create a realistic training aid that feels and responds to the surgical airway procedure including the mounting of a trachea model and the bleeding from the surgical site common to the surgical airway procedure. Additionally, the airway medical training device is low profile creating a realistic and natural outward appearance and conform to the role player wearing it. The integration of a flexible steel mesh system allows for safe training of the Open Surgical Airway Procedure (OSAP), see FIGS. 7A through 7C. This device is capable rapid resetting after use facilitating large groups of trainees. The carotid wound configuration allows for the user to simulate a carotid bleeding wound requiring wound packing and a subsequent surgical airway placement. The burn configuration presents the appearance of burned skin indicated the need for open surgical airway. Additional configurations may also include the addition of simulated swelling with the use of fluid-filled reservoirs 15 indicating the collection of blood under the skin (front panel) of the neck necessitating OSAP, and thus a good training tool.
A method of making the present invention may include the following. First, a manufacturer may make the present invention using two molds layered with a synthetic leather to create a skin-like appearance of the colored silicone that is poured into the mold. Each part may be molded separately and may have a high performance, four-way stretch nylon impregnated into the silicone prior to completion of the cure period. The base plate may have a layer of steel mesh that is placed into the silicone to be completely encapsulated into the model allowing for no visibility of the metal insert in the final product. After the silicone has cured the excess stretch nylon is trimmed from each model. Removable fasteners may be sewn onto the model at specific location outlined in the attached picture using colored thread on a standard sewing machine or adhering via adhesive substances. The removable colors may be matched to the a plurality skin tones that the device is made in including light, medium and dark skin. The sacrificial skin made in a leather covered flat mold measuring 20×15 inches and then is cut into twenty-five individual silicone squares. The blood reservoir may be made from a vacuum seal bag measuring 3×6 inches where 5-25 ml of red colored fluid is placed inside the bag and heated sealed using a vacuum sealer.
A method of using the present invention may include the following. The wearable airway medical training device 100 disclosed herein may be provided. A medical licensed medical trainer (end-user) would assemble the device and configure it for either a non-wounded neck or a wounded neck configuration depending on their training needs. The assembled device would then be attached to a role player who would make the actions and sounds of a person with an airway obstruction. The end-user would then direct a trainee to assess the patient and perform an open surgical airway procedure. The trainee can continue the medical scenario at the direction of end-user. After the training scenario is completed, the role player will remove the device and the end-user will reset the device for another scenario. This device allows for realistic and rapid open procedure surgical airway training. The profile of this devise allows the end-user to create complex scenarios while maintaining a realistic appearance. The unique safety features of this device in the form of flexible steel mesh allows for safe surgical airway training while maintaining safety of the role player.
It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
