Abstract
Abstract An apparatus for administering fluids through the nose by means of a tube is provided which comprises a tube having a distal end and a proximal end. The proximal end of the tube when no administration is being carried out is secured in position and disposed removably within the nasal vestibule for the administering. This ensures that during this time when no administering is being carried out, the proximal end of the tube is mounted invisibly within the nose whilst for administering the fluid it can easily be removed from the nasal vestibule and connected to the fluid container.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
189 words
Apparatus for administering fluids through the outer opening of a nostril by means of a tube having a distal end and a proximal end comprising a bearing member having a passageway therethrough, said bearing member having an outer surface adapted to fit snugly into the nasal vestibule of the nostril in which it is utilized in such a manner that substantially no air can pass between said outer surface and said vestibule, said passageway having an internal bearing face and connecting the outer opening of the nostril with the nasal cavity and having dimensions which are sufficient to permit the passage therethrough of a nasal feeding tube and which are greater at the end of the passageway proximal to the outer nostril opening than distal thereto, a feeding tube having a distal end and a proximal end, and a connector means adapted to fit into the proximal end of the feeding tube having a dimension perpendicular to the principle axis of the feeding tube greater than the minimum dimension of the said passageway but less then its maximum dimension and being adapted to rest against said internal bearing face.
Claim 2
Dependent Claim
189 words
Apparatus for administering fluids through the outer opening of a nostril by means of a tube having a distal end and a proximal end comprising a bearing member having a passageway therethrough, said bearing member having an outer surface adapted to fit snugly into the nasal vestibule of the nostril in which it is utilized in such a manner that substantially no air can pass between said outer surface and said vestibule, said passageway having an internal bearing face and connecting the outer opening of the nostril with the nasal cavity and having dimensions which are sufficient to permit the passage therethrough of a nasal feeding tube and which are greater at the end of the passageway proximal to the outer nostril opening than distal thereto, a feeding tube having a distal end and a proximal end, and a connector means adapted to fit into the proximal end of the feeding tube having a dimension perpendicular to the principle axis of the feeding tube greater than the minimum dimension of the said passageway but less then its maximum dimension and being adapted to rest against said internal bearing face.
Claim 3
Dependent Claim
33 words
An apparatus of claim 1 wherein said passageway has dimensions which are sufficient to permit the passage therethrough of a nasal feeding tube and a sufficient quantity of air to permit regular breathing.
Claim 4
Dependent Claim
13 words
An apparatus of claim 2 wherein said connector is provided with a flange.
Claim 5
Dependent Claim
27 words
An apparatus of claim 1 characterized in that the surface of the bearing member has a slight roughness and the bearing member consists of physiologically compatible material.
Claim 6
Dependent Claim
123 words
Apparatus for administering fluids through the outer opening of a nostril by means of a tube having a distal end and a proximal end comprising a bearing member having a cavity therein, said bearing member having an outer surface adapted to fit snugly into the nasal vestibule of the nostril whereby substantially no air can pass between said outer surface and said vestibule, a feeding tube having a distal end and a proximal end, a connector means adapted to fit into the proximal end of the feeding tube, said cavity having a single opening facing the nasal cavity of sufficient size to admit said connecting means therein and an internal bearing face with means to releasably hold said connector means within said cavity.
Claim 7
Dependent Claim
123 words
Apparatus for administering fluids through the outer opening of a nostril by means of a tube having a distal end and a proximal end comprising a bearing member having a cavity therein, said bearing member having an outer surface adapted to fit snugly into the nasal vestibule of the nostril whereby substantially no air can pass between said outer surface and said vestibule, a feeding tube having a distal end and a proximal end, a connector means adapted to fit into the proximal end of the feeding tube, said cavity having a single opening facing the nasal cavity of sufficient size to admit said connecting means therein and an internal bearing face with means to releasably hold said connector means within said cavity.
Claim 8
Dependent Claim
40 words
An apparatus of claim 5 wherein said bearing face is provided with a thread, and said connector is provided with a plug means insertable therein, said plug means having an external thread interactable with the thread in said bearing face.
Claim 9
Dependent Claim
40 words
An apparatus of claim 5 wherein said bearing face is provided with a pin means insertable in said connector and the bearing face surrounding said pin means is provided with a thread interactable with the external surface of said connector.
