Problems solved by technology

On the downside, this complex design makes the check valve harder and more expensive to manufacture
Conventional check valves with complex designs are also more difficult to clean, maintain, repair and replace
Also, the complex design and multiple sections of some known check valves are more prone to failure

Embodiment Construction

[0044] It will be readily understood that the components of the present invention, as generally described and illustrated in the drawings herein, may be arranged and designed in a variety of different configurations. Accordingly, the following more detailed description of the preferred embodiments is not intended to limit the scope of the invention as claimed, but to merely characterize some of the presently preferred embodiments of the invention.

[0045] The present invention generally relates to a one-way valve for use in conjunction with, for example, suction valves for ventilation tubes and tracheostomy speaking valves. However, it should be understood that the one-way valve may be used in conjunction with other types of equipment and in other suitable environments. For example, a one-way valve can be used to regulate the flow of any type of fluid or flowable material such as air, water, blood, and the like. Thus, the one-way valve can be used with artificial heart valve...

Abstract

A check valve made up of a substantially rigid portion and a substantially flexible membrane that is generally dome shaped. The substantially rigid portion includes one or more spokes that meet in the center of the rigid portion and one or more partial spokes extending part way to the center of the rigid portion. The dome shaped, substantially flexible membrane also includes one or more flexible spokes and one or more collapse zones. The completed check valve is made by connecting a center portion of the substantially rigid portion to a center portion of the dome shaped, substantially flexible membrane.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit to U.S. Patent Application No. 11 / 248,900, filed October 11, 2005, entitled CHECK VALVE, which claims US PROVISIONAL PATENT APPLICATION NO. FOR VALVES, BAFFLES, SHORTENED SNORKELS, STEALTH SNORKELS, SNORKEL EQUIPMENT COMBINED WITH SCUBA EQUIPMENT FOR VALVES, BAFFLES, SHORTENED SNORKELS, SNORKEL EQUIPMENT COMBINED WITH SCUBA EQUIPMENT 60 / 683,477 priority and rights. Each of said applications is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to valves, and more particularly to one-way valves for allowing fluid flow in one direction and preventing fluid flow in the opposite direction. Background technique [0004] A conventional one-way valve is a device that allows gas, liquid, or other fluid to flow in one direction. In particular, conventional one-way valves allow fluid to flow in the intended direction w...
