Embodiment Construction

[0026]FIG. 1 illustrates an exemplary embodiment of a medical vacuum aspiration device (MVA) 10. The MVA 10 may include a cannula 100, a valve 200, and an aspirator cylinder 300. The cannula 100 removably connects to a first opening of valve 200 and the aspirator cylinder 300 removably connects to a second opening of the valve 200. The valve 200 opens and closes fluid communication between the cannula 100 and the aspirator cylinder 300.

[0027] Referring to FIGS. 2 and 3, the valve 200 may include a housing 202, a cap 204, buttons 206, and a fluid conduit 208. The housing 202 includes first and second fluid openings 210, 212 into which the cannula 100 and the aspirator cylinder 300, respectively, are inserted. The housing 202 can be opened to permit access to and removal of the fluid conduit 208. As shown in FIG. 3, an interior of housing 202 receives at least part of the fluid conduit 208. According to one embodiment, each end of the fluid conduit 208 extends outward beyond the resp...

Abstract

A medical vacuum aspiration device includes an aspiration cylinder and a valve. The valve includes a removable fluid conduit, a valve housing having at least first and second housing portions, means for removably attaching the first housing portion to the second housing portion, and an actuator. The removable fluid conduit has a first end for attaching to a cannula and a second end for attaching to the aspiration cylinder. The first and second housing portions may define a cavity for removably holding at least a portion of the fluid conduit. The actuator is coupled to the valve housing and selectively compresses a portion of the fluid conduit to open and close a fluid path defined by the fluid conduit.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a medical vacuum aspiration device (MVA). In general, it is more economical for MVAs to be used multiple times before they are disposed. Between uses, the MVA should be sterilized and / or disinfected. However, the materials chosen for the components of the MVA may be susceptible to degradation and / or damage by certain sterilization procedures and disinfectants. For example, latex components of the MVA can oxidize in an autoclave and certain plastic components can melt in an autoclave or degrade in the presence of chemical disinfectants. [0002] Some MVAs are difficult to adequately clean and sterilize because they cannot be disassembled sufficiently. Other MVAs can include multiple parts that can be disassembled for sterilizing and disinfecting. However, the parts are easily misplaced or lost when disassembled. Further, a plurality of interfaces must be provided between each of the parts in order to connect the parts ...
