Abstract: An ice tip is placed on the front end of a hypodermic needle to cool the flesh during insertion. The ice tip front end is sharp, for penetration, and the rear is provided with a recess, for reception of a hypodermic needle front end. The mold for forming the ice tip can be cooled by a cryogenic fluid being conducted into a main mold surrounding a tip forming heat conducting mold that is used to form the ice tip pointed front end and the recessed rear end.

Abstract: An ice coating is placed on the hypodermic needle to cool the flesh during insertion. The ice coated front end is sharp, for penetration. The ice coating can be formed by cooling the needle and dipping it in water or molding ice onto the needle. A refrigeration chamber or cryogenic chamber can be used to cool the needle. The mold for forming an ice coating can be cooled by a cryogenic fluid or refrigerant being conducted into coils of the mold surrounding heat conducting mold walls that are used to form the ice coating on the needle. The water can be sterilized with disinfectant included.

Abstract: A tongue stabilizer includes a tongue-engaging plate that is held on a laryngoscope blade by pressure sensitive adhesive, with a foam strip in-between to compensate for any irregularities between the tongue-engaging plate and the laryngoscope blade. The tongue-engaging plate is cup shape to cradle the tongue to prevent the tongue from interfering with the visibility and process of intubation. A protective strip can be used to cover the adhesive.

Abstract: A sterile, disposable laryngoscope blade sheath for use in the intubation process is disclosed. The sheath either provides for or permits the laryngoscope structure to perform the desired or designed functions. Such functions may be, for example, the manipulation of the epiglottis while maintaining the tongue positioned. This is accomplished by either providing an opening in the end of a rigid sheath for the shaped blade end to project through, or by shaping the rigid sheath so that it can perform the function using or independent of the blade end shape, or by providing a resilient end section that assumes or conforms to the shape of the blade.

Abstract: This disclosure is directed to an improved laryngoscope blade sheath for use in the intubation process to maximize laryngoscope use by providing a single unit to orchestrate the laryngescope and the endotracheal tube. This invention is a sterile, disposable, generally linguiform laryngoscope blade sheath. The sheath is made mostly from a fairly rigid material. The inside of the sheath is hollow so that all the common standard laryngoscope blades can be inserted through its aperture. The width of the sheath is wider than the common blades and the shape of the sheath is curved and spoon-like so that the tongue can be lifted stably without slipping. There are orifices on the underneath surface of the sheath so that the light of the laryngoscope blade can shine through these orifices and the trachea can be visualized. The sheath also has an intubation guide groove underneath to make intubation more efficent. Because this sheath is used only once there is no danger of cross infection.
