Embodiment Construction

[0023] Referring now to the drawings in detail, numeral 10 designates a device according to a first embodiment of the present invention. Device 10 includes an elongated hollow body 12 having a first cylindrical portion 14 , an integrally connected intermediate conical portion 16 , and a mask 18 integrally connected to intermediate portion 16 . A central bore 20 is formed in the body 12 extending from the mask opening 22 through the mask 18 , the conical portion 16 and the body 14 .

[0024] An adjustable threaded cap 24 closes a normally closed end 26 of the body portion 14 . The cap 24 is provided with threads 28 on the inner wall of the cap. A central plug 32 is formed in the cap and projects outwardly from an inner end 34 of the cap 24 . As best seen in Figure 3, the end 34 forms an annular shoulder which provides a first abutment surface against which the compression spring 40 bears, as described in more detail below.

[0025] An inhalation port 42 is cut through the wa...

Abstract

A hand-held breathing device for use by patients having respiratory problems creates a sealed backpressure in the airways of the patient by creating resistance to exhalation. A peep valve is mounted inside a hollow body, and a pre-set compression spring is mounted between the valve and an adjustable cap or cam lever in the main body of the device. A pair of valve openings extend through the wall of the main body, one opening serving as an intake port for inhaling of air by the patient and the second port-for exhalation of carbon dioxide. An intake valve is mounted inside the body between a normally open end of the device and the exhalation valve. In one of the embodiments, the device is attached to a nebulizer to facilitate buildup of positive pressure and delivery of medication to the patients' lungs.

Description

[0001] Cross-References to Related Applications [0002] This application is a continuation-in-part of applicant's co-application 471,533 entitled "Sealed Back Pressure Attachment Device for Nebulizer," filed December 23, 1999, the contents of which are incorporated herein by reference in their entirety . technical field [0003] The present invention relates to a device for assisting the lung function of a patient; it can be used alone for exercising the muscles involved in breathing or in combination with a nebulizer for delivering medicine to the patient's airway. In particular, the present invention relates to devices that create a positive back pressure within the airway of a user to maintain the airway and restore normal breathing. Background technique [0004] Nebulizers are the most widely used device for assisting people with breathing difficulties; nebulizers aid in drug delivery during asthma attacks, emphysema attacks, and similar conditions. Nebulizers are com...
