Abstract
Abstract An instrument for administering fluid into a body through an orifice therein, which consists of a tube having an orifice entering end having means for being retained on the body during the administration of the fluid. The retaining means consists of an enlargement surrounding the tube adjacent said end and having concentric inner and outer concavities formed in its frontal surface defined by ridges adapted to form a seal with the body surface around the orifice; the outer concavity having an opening through its wall through which its interior is connected to an air exhaust pump; the means connecting the concavity opening with the air pump including a one-way air valve.

Total Claims: 8
Claim 1
Independent Claim
151 words
An instrument for administering fluid into a body through an orifice therein, comprising a tube having a frontal end insertable into said orifice, an enlargement surrounding said tube distally of its said frontal end, said enlargement having a first frontally facing concavity formed therein, said concavity defined by an outer peripheral edge and an inner peripheral edge, said inner peripheral edge spaced from said tube, said peripheral edges adapted to form a sealing contact with the body area surrounding said orifice when said frontal end is inserted into said orifice, said concavity having an opening formed in a wall portion thereof, and air exhaust means connected to said enlargement adapted to exhaust air from said concavity through said opening, said enlargement having a second frontally facing concavity between said first concavity and said tube, said second concavity defined from said first concavity by said inner peripheral edge of said first concavity.
Claim 2
Dependent Claim
151 words
An instrument for administering fluid into a body through an orifice therein, comprising a tube having a frontal end insertable into said orifice, an enlargement surrounding said tube distally of its said frontal end, said enlargement having a first frontally facing concavity formed therein, said concavity defined by an outer peripheral edge and an inner peripheral edge, said inner peripheral edge spaced from said tube, said peripheral edges adapted to form a sealing contact with the body area surrounding said orifice when said frontal end is inserted into said orifice, said concavity having an opening formed in a wall portion thereof, and air exhaust means connected to said enlargement adapted to exhaust air from said concavity through said opening, said enlargement having a second frontally facing concavity between said first concavity and said tube, said second concavity defined from said first concavity by said inner peripheral edge of said first concavity.
Claim 3
Dependent Claim
11 words
The instrument of claim 1, wherein said concavities surround said tube.
Claim 4
Dependent Claim
15 words
The instrument of claim 1, wherein said concavities surround and are concentric with said tube.
Claim 5
Dependent Claim
29 words
The instrument of claim 3, wherein said tube is formed with an enlarged orifice-entering head at its said frontal end and said enlargement is formed distally of said head.
Claim 6
Dependent Claim
77 words
The instrument of claim 4, wherein the peripheral edges of said first concavity are disposed in longitudinally offset relation to one another with said outer peripheral edge thereof disposed distally of said inner edge thereof, and said second concavity is formed with an inner peripheral edge frontally offset relative to the inner edge of said first named concavity and defined by the intersection of the surface of said second concavity with the distal end of said head.
Claim 7
Dependent Claim
83 words
The instrument of claim 4, wherein said air-exhaust means include a closed chamber connected to said enlargement, distally thereof, the interior of said chamber communicating with the interior of said first concavity through said opening, said chambeR having an opening formed in a wall portion thereof, and means connecting the interior of said chamber to an air exhaust mechanism, said connecting means including a one-way air valve adapted to permit passage of air outwardly of said chamber and inhibiting movement of air thereinto.
Claim 8
Dependent Claim
53 words
The instrument of claim 1, wherein said air-exhaust means includes an air exhaust mechanism and means connecting said mechanism to said first concavity through said opening, said connecting means including a one-way valve adapted to permit passage of air out of said first concavity and inhibiting passage of air thereinto through said opening.
