Abstract: A method and an apparatus for applying an anesthetic that includes a receptacle having an upper end, a substantially hollow interior, a lower end having a tube or nozzle extending therefrom, and an attachment for attaching to the barrel of a syringe or vice versa. The receptacle receives a container or canister containing an endothermic gas or vapor (propellant) that rapidly absorbs heat when released to the atmosphere. A depressible actuating member or trigger propels the gas or vapor through an outlet nozzle that is oriented to project a stream of gas or vapor along a delivery axis that intersects a delivery axis of the needle, therefore, the gas or vapor can be successively delivered to an injection site with minimal repositioning of the housing.

Abstract: The present device provides a method and an apparatus for applying a vaporized endothermic gas to a skin surface to provide numbing of the application site for injection with a syringe. The device includes a container or canister containing an endothermic gas that rapidly absorbs heat when released to the atmosphere. A depressible actuating member or trigger propels the gas or vapor through an outlet nozzle that is constructed to break the liquid into a vapor that can be projected as a stream of vapor along a delivery axis that intersects a delivery axis of the syringe needle; therefore, the gas or vapor can be successively delivered to an injection site with minimal repositioning of the device.

Abstract: A medical procedure accessory components holding unit and methods of using thereof. The accessory holder is designed to hold and store one or more components or medical devices that could be used in a medical procedure, particularly medical devices, for applying an anesthetic. The accessory holder may include four (4) medical device storage or use modules: a syringe disposal device module, a dispensing tool module, a canister module, and a syringe attachment module.

Abstract: A method and an apparatus for applying an anesthetic include an elongated tubular housing having an upper end, a substantially hollow interior, and a lower end having an injection needle extending therefrom. A first chamber is formed within the housing interior for holding an anesthetic cartridge therein. A second chamber receives a cannister containing an endothermic gas that rapidly absorbs heat when released to the atmosphere. The cartridge is penetrated by a plunger that forces the anesthetic through the injection needle. A depressible trigger propels the gas through an outlet nozzle that is oriented to project a stream of gas along a delivery axis that intersects a delivery axis of the needle; therefore, the gas and anesthetic can be successively delivered to an injection site with minimal repositioning of the housing. Accordingly, a dental practitioner can initially disperse the endothermic gas onto the injection site to minimize any pain and discomfort associated with an injection.
