Abstract

Abstract A vaginal and cervical device comprising an elongated tubular member with an air tube connected to a pressure source at one end, a tubular extension structure at the distal end comprised of inner and outer sheets of flexible material which define an air chamber and which may be collapsed into the distal end of the tubular member or deployed therefrom into a fully extended position to provide an opening for observation of a cervix to aid in artificial insemination. Air from the pressure source maintains the tubular extension in the extended position. The outer sheet of the tubular extension may be stretchable to define an expander which is inflated by way of the pressure source or, alternatively, a separate expander may be mounted on the medial portion of the tubular member either of which press against the walls of the vagina to hold the device firmly in place.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 189 words
A device comprising an elongated tubular member with a proximal end and a distal end, an air passageway extending between said proximal and distal ends, a pressure source connected to said passageway, and an extension structure mounted to said distal end, said extension structure being selectively movable between a collapsed position and an extended position, said extension structure being longitudinally disposed beyond said distal end when in said extended position, said extension structure including an air chamber in communication with said passageway for receiving air from said pressure source to maintain said extension structure is a generally tubular configuration when in said extended position to defein an opening at the outer end thereof in general longitudinal alignment with the distal end of said tubular member, said extension structure comprising inner and outer sheets of flexible material oppositely disposed of each other and defining said air chamber and being disposed substantially within the tubular member near the distal end when in collapsed condition, said inner and outer sheets being of substantially non-stretchable material such that they are influenced laterally a negligible amount under the influence of pressure from said source.
Claim 2
Independent Claim 189 words
A device comprising an elongated tubular member with a proximal end and a distal end, an air passageway extending between said proximal and distal ends, a pressure source connected to said passageway, and an extension structure mounted to said distal end, said extension structure being selectively movable between a collapsed position and an extended position, said extension structure being longitudinally disposed beyond said distal end when in said extended position, said extension structure including an air chamber in communication with said passageway for receiving air from said pressure source to maintain said extension structure is a generally tubular configuration when in said extended position to defein an opening at the outer end thereof in general longitudinal alignment with the distal end of said tubular member, said extension structure comprising inner and outer sheets of flexible material oppositely disposed of each other and defining said air chamber and being disposed substantially within the tubular member near the distal end when in collapsed condition, said inner and outer sheets being of substantially non-stretchable material such that they are influenced laterally a negligible amount under the influence of pressure from said source.
Claim 3
Dependent Claim 46 words
The device set forth in claim 1 including a sleeve of flexible, stretchable material attached to said tubular member intermediate said distal and proximal ends thereof and in communication with said pressure source to define an inflatable expander for holding said device in place during use.
Claim 4
Independent Claim 165 words
A device for enabling observation of and access to a body cavity through a body passageway comprising an elongated, substantially rigid tubular member adapted to be inserted into a body passageway and defining a bore enabling observation and access therethrough to the body cavity, a collapsible and extendible extension on one end of said tubular member, said extension being connected with said tubular member and having an open end remote from the tubular member to enable observation and access therethrough, said open end of the extension being larger than the tubular member and disposed axially beyond the end of the tubular member to which the extension is connected, illumination means carried by said device for illuminating the area of the body cavity encompassed by the open end of the extension, and means extending and collapsing said extension from the end portion of the tubular member remote from the extension for anchoring the extension in the body cavity and the tubular member in the body passageway.
Claim 5
Independent Claim 165 words
A device for enabling observation of and access to a body cavity through a body passageway comprising an elongated, substantially rigid tubular member adapted to be inserted into a body passageway and defining a bore enabling observation and access therethrough to the body cavity, a collapsible and extendible extension on one end of said tubular member, said extension being connected with said tubular member and having an open end remote from the tubular member to enable observation and access therethrough, said open end of the extension being larger than the tubular member and disposed axially beyond the end of the tubular member to which the extension is connected, illumination means carried by said device for illuminating the area of the body cavity encompassed by the open end of the extension, and means extending and collapsing said extension from the end portion of the tubular member remote from the extension for anchoring the extension in the body cavity and the tubular member in the body passageway.
Claim 6
Dependent Claim 88 words
The structure as defined in claim 3 wherein said extension includes inner and outer panels of flexible material having outer ends connected together to define the open end of the extension, said panels having inner ends connected to said tubular member to define a closed space between said panels, said means extending and collapsing said extension including fluid pressure means communicated with the closed space between the panels to extend the extension when fluid pressure enters the space and permit collapse thereof when fluid pressure is exhausted therefrom.
Claim 7
Dependent Claim 33 words
The structure as defined in claim 4 wherein said outer panel is extended into anchoring engagement with the body cavity when extended and being constructed of resilient material to enable enlargement thereof outwardly.
Claim 8
Dependent Claim 37 words
The structure as defined in claim 5 wherein said fluid pressure means includes an air tube extending along the tubular member, said illumination means including a small light mounted interiorly of the tubular member adjacent the extension.
Claim 9
Dependent Claim 64 words
The structure as defined in claim 3 wherein said extension is flexible and capable of assuming a dimension not greater than the tubular member when collapsed to facilitate insertion of The device into a bovine vagina with the open end of the extension adapted to confront the cervix to enable location and observation thereof and to facilitate insertion of a pipette for artificial insemination.
