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 . image 3 As best seen in FIG. 1 , end 34 forms an annular shoulder that provides a first abutment surface against which compression spring 40 bears, as described in more detail below.

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

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 the continuation of the 471,533 common application entitled "Sealed Back Pressure Attachment Device for Nebulizer" (Sealed Back Pressure Attachment Device for Nebulizer) submitted by the applicant on December 23, 1999, the contents of which are incorporated herein in their entirety Reference. 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...
