Cricothyroidotomy simulation device
An artificial anatomical model used in an embodiment as a simulation and training device for performing a cricothyroidotomy procedure on a patient having an upper airway obstruction is provided. Furthermore, the simulation device includes a mandible and neck base structure that geometrically mimics a human mandible and neck region with corresponding anatomical landmarks such that a cricothyroidotomy procedure can be performed on the device for training purposes in some embodiments. Moreover, various components of the device are easily removable and replaceable independent of one another, further simplifying the training process.
1. A method of reloading a cricothyroidotomy model for subsequent training usage, the model comprising (a) a mandible and neck base structure that geometrically mimics at least a portion of the mandible and neck comprised of, at least in part, a muscle portion, and a skin layer disposed over said muscle portion, said base structure defining a tracheal access window; (b) a tracheal structure disposed within and removable from the base structure; said tracheal structure comprises a tracheal aperture that is aligned with the tracheal access window, (c) a replaceable cricoid membrane surrounding the tracheal structure at the tracheal opening; (d) a hyoid cartilage component affixed at one end to the tracheal structure and disposed ventral to the cricoid membrane; and (e) a replaceable skin component disposed over the base structure at the tracheal access window but ventral to the hyoid cartilage component
wherein the method comprises
removing at least in part the skin layer from the muscle portion;
removing said replaceable skin component;
removing said cricoid membrane from said tracheal structure;
putting a replacement cricoid membrane onto said tracheal structure;
putting a replacement skin component over said tracheal structure above said cricoid membrane; and
returning said skin layer over said muscle portion whereby said tracheal access window is aligned with a portion of said replaceable skin component.
2. The method of claim 1 , further comprising displacing the hyoid cartilage component from the cricoid membrane prior to removing the cricoid membrane from the tracheal structure.
3. The method of claim 2 , further comprising repositioning the hyoid cartilage component is over at least a portion of the replacement cricoid membrane and under at least a portion of the replacement skin component.
