Embodiment Construction

[0029] The device of the present invention includes a mouthpiece configured so that when the device is properly used by the patient, the mouthpiece will urge the patient's lower jaw into place to increase deposition of the inhaled medicinal aerosol in the patient's lungs. The device of the present invention increases the deposition of an inhaled pharmaceutical aerosol in a patient's lungs by modifying the geometry of the patient's mouth to create a laminar flow of the gas / inhaled pharmaceutical aerosol mixture. Proper positioning of the patient's jaw and associated anatomy will reduce deposition of inhaled medicinal aerosol particles in the upper airway and increase deposition in the lungs.

[0030] figure 1 5 shows an exemplary embodiment of an apparatus 10 according to an embodiment of the present invention. The device 10 comprises a hollow body 11 having a front end 12 , a rear end 30 and an imaginary axis 50 passing through the hollow body 11 . The device 10 comprises a ...

Abstract

The present invention relates to an apparatus (10) to aid in administering inhaled pharmaceutical aerosol to a patient. The apparatus (10) is used in conjunction with an aerosol delivery device. The apparatus comprises steps (32, 34) on the top and bottom of the apparatus (10), which when used aid the patient causes mandibular advancement, and opening of the mouth, causing opening of patient's airway, resulting in improved aerosol lung deposition. The invention also relates to a method of using such apparatus in a combination with an aerosol delivery device or a system, and to the mouthpiece of said apparatus.

Description

[0001] The present application claims the benefit of priority under 35 USC §119(e) to US Provisional Application No. 61 / 140,138, filed December 23, 2008, the contents of which are incorporated herein by reference. technical field [0002] The present application relates to devices for assisting in spraying inhaled medicinal aerosols to patients. The invention also relates to methods of using such devices in conjunction with aerosol delivery devices or systems. Background technique [0003] Medical devices for delivering drugs to patients in aerosol form have been in use since the mid-1950s. This device is used to deliver an inhaled pharmaceutical aerosol (IPA) into the lungs of a patient. The most common use of this device is to treat asthma and chronic obstructive pulmonary disease, in the form of metered dose inhalers, dry powder inhalers or nebulizers. [0004] A frequent problem with the use of inhalers is the inefficiency in delivering the aerosol to the target. Wher...
