Benefits of technology

"The patent describes a breathing bag that has a connector portion and a distensible portion. The connector portion is thick enough to be connected directly to a male fitting, while the distensible portion has a flute design. The technical effect of this design is that it allows for easy connection and flexibility in the breathing bag, making it more comfortable and efficient for users."

Problems solved by technology

Such process is typically slow, unwantedly expensive and lends itself to imperfections.
Further, the typical prior art breathing bag made by the aforenoted dipping process and has a relatively thin wall thickness such that the connector portion is insufficiently stiff or rigid to connect, for example, to a standard 22 mm tapered male fitting or a non-tapered tubular or hollow cylindrical fitting.
Such thickness means that the neck portions 4 are insufficiently stiff or rigid to be connected directly to one of the above-noted male fittings.
As is further known to the art, the requirement of these additional bushings, the retaining bands, and the manufacturing steps required to insert and retain the bushings in the breathing bags further add unwanted cost and expense to the manufacture of the typical prior art breathing bag.

Embodiment Construction

[0023] A breathing bag embodying the present invention is illustrated diagrammatically in FIGS. 6 and 6A and indicated by alphabetical designation B. Breathing bag B includes a generally cylindrical connector portion C and a distensible portion D. The connector portion C is typically sized to connect directly to an ISO 22 mm male fitting and the distensible bag D expands and contracts in the process of delivering, or assisting in delivering, gas to the patient as noted above. As will be better understood from FIG. 6A, the connector portion C has a greater thickness than the thickness of the distensible portion D; the greater thickness of the connector portion C provides it with the strength or rigidity to serve its above-noted connector function. For illustration the thickness of the connector portion C has been exaggerated with respect to the thickness of the distensible portion D in FIG. 6A. In one embodiment, the distensible portion D had a thickness or wall thickness T1 of about...

Abstract

A breathing bag including a distensible bag portion and an integrally formed neck portion thicker than the distensible bag portion and sufficiently thick to be connected directly to a male fitting; the distensible bag portion may be fluted.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation application of pending application Ser. No. 10 / 843,769, filed May 12, 2004, which is a divisional application of application Ser. No. 10 / 176,906, filed Jun. 21, 2002, both entitled PROCESS OF MANUFACTURING A BREATHING BAG AND BREATHING BAG MANUFACTURED BY SUCH PROCESS, Jack H. Britten, et al., inventors, and assigned to the same assignee as this continuation application.BACKGROUND OF THE INVENTION [0002] This invention relates to a breathing bag including connector and distensible portions. [0003] Breathing bags are well known to the medical arts for delivering, or assisting in delivering, gas to a patient such as anesthesia gas or a breathing gas such as oxygen or oxygen-enriched air. Typical prior art breathing bags are illustrated diagrammatically in FIGS. 1A and 1B, FIGS. 2A and 2B, FIGS. 3A, 3B, 3C and 3D and FIGS. 4A, 4B and 4C. [0004] These prior art breathing bags typically include connector and...
