Abstract
Abstract A tube construction and, specifically, a nasogastric tube construction is provided for patient treatment. An elongated generally flexible tube of a selected diameter permits insertion of one end of the tube into a body orifice, such as the nasal cavity, of the patient. The flexible tube is of a selected length to extend from the body orifice to a remote connection. A tube sheath covers a predetermined portion of the tube adjacent to the body orifice. The tube sheath has one end positioned adjacent the body orifice and is of sufficient length to extend from the body orifice to a position along the tube generally beyond the normal reach of the patient. Fastening straps affixed to the tube sheath anchor the tube sheath to the patient so that an end of the tube sheath is held in position adjacent the body orifice to prevent patient access to the tube covered by the sheath. The fastening straps are inelastic to prevent the patient from pulling the tube sheath away from the orifice and gaining access to the portion of the tube proximate the orifice. The tube sheath and fastening straps prevent removal of the tube by the patient.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
220 words
A tube construction for patient treatment comprising: an elongated generally flexible tube of a selected diameter to permit insertion of one end into a body orifice of a patient and of a selected length to extend from the body orifice to a remote connection; a tube sheath for covering a predetermined portion of the tube adjacent said body orifice, the tube sheath having one end to be positioned adjacent the body orifice of the patient and a sufficient length to extend from the body orifice to a position along the tube generally beyond the normal reach of the patient, the tube sheath having retention means to prevent the sheath from being retractable over the portion of the tube covered by the sheath to deny patient access to the tube; and sheath holder means for anchoring the tube sheath to the patient so that the end of the tube sheath is held in position adjacent the body orifice to prevent patient access to the tube covered by said sheath, said holder means being inextensible so that when the holder is in position on the patient, it prevents the patient from pulling the tube sheath away from the orifice and gaining access to the portion of the tube proximate the orifice in order to prevent dislodgement of the tube by the patient.
Claim 2
Dependent Claim
220 words
A tube construction for patient treatment comprising: an elongated generally flexible tube of a selected diameter to permit insertion of one end into a body orifice of a patient and of a selected length to extend from the body orifice to a remote connection; a tube sheath for covering a predetermined portion of the tube adjacent said body orifice, the tube sheath having one end to be positioned adjacent the body orifice of the patient and a sufficient length to extend from the body orifice to a position along the tube generally beyond the normal reach of the patient, the tube sheath having retention means to prevent the sheath from being retractable over the portion of the tube covered by the sheath to deny patient access to the tube; and sheath holder means for anchoring the tube sheath to the patient so that the end of the tube sheath is held in position adjacent the body orifice to prevent patient access to the tube covered by said sheath, said holder means being inextensible so that when the holder is in position on the patient, it prevents the patient from pulling the tube sheath away from the orifice and gaining access to the portion of the tube proximate the orifice in order to prevent dislodgement of the tube by the patient.
Claim 3
Dependent Claim
45 words
The tube construction of claim 1 in which the sheath holder means comprises two elongated generally inelastic fastening members fixed to the sheath so that the fastening members may be secured together around a portion of the patient's body to hold the sheath in position.
Claim 4
Dependent Claim
36 words
The tube construction of claim 2 in which the two members are of a length to extend around the patient, so that the ends may be tied together at a position remote from said body orifice.
Claim 5
Dependent Claim
14 words
The tube construction of claim 1 in which the tube sheath comprises cloth material.
Claim 6
Dependent Claim
20 words
The tube construction of claim 1 wherein said tube is a nasogastric tube and said body orifice is said nose.
Claim 7
Dependent Claim
59 words
The tube construction of claim 5 wherein said sheath holder means comprises two elongated generally inelastic fastening members fixed to the sheath and having a length so that the fastening members may be secured together generally behind the patient's head to hold the sheath in position extending outwardly from the nose of the patient away from the patient's face.
Claim 8
Dependent Claim
18 words
The tube construction of claim 1 in which said retention means comprises a compositional structure of the sheath.
Claim 9
Dependent Claim
15 words
The tube construction of claim 7 in which the compositional structure is a semi-rigid material.
Claim 10
Dependent Claim
16 words
The tube construction of claim 8 in which said semi-rigid material comprises a synthetic resinous material.
Claim 11
Dependent Claim
21 words
The tube construction of claim 9 in which said semi-rigid material comprises a plastic material derived from the synthetic resinous material.
Claim 12
Dependent Claim
33 words
The tube construction of claim 7 in which said retention means comprises a fastener for securing the sheath to the tube at a selected position along said sheath distal to the body orifice.
Claim 13
Dependent Claim
22 words
The tube construction of claim 11 in which said selected position along said sheath is beyond the normal reach of the patient.
Claim 14
Dependent Claim
44 words
The tube construction of claim 11 in which said tube has an enlarged diameter portion disposed intermediate the remote connection and the body orifice, and said selected position along said sheath for said fastener is between said enlarged diameter portion and said remote connection.
Claim 15
Dependent Claim
20 words
The tube connection of claim 11 in which said fastener is a tie for tying around the sheath and tube.
Claim 16
Dependent Claim
33 words
The tube construction of claim 1 in which said retention means comprises a fastener for securing the sheath to the tube at a selected position along said sheath distal to the body orifice.
Claim 17
Dependent Claim
22 words
The tube construction of claim 15 in which said selected position along said sheath is beyond the normal reach of the patient.
Claim 18
Dependent Claim
44 words
The tube construction of claim 15 in which said tube has an enlarged diameter portion disposed intermediate the remote connection and the body orifice, and said selected position along said sheath for said fastener is between said enlarged diameter portion and said remote connection.
Claim 19
Dependent Claim
20 words
The tube construction of claim 15 in which said fastener is a tie for tying around the sheath and tube.
Claim 20
Dependent Claim
24 words
The tube construction of claim 1 in which the retention means prevents the patient from bending the sheath to gain access to the tube.
Claim 21
Dependent Claim
19 words
The tube construction of claim 19 in which said retention means comprises a rigid compositional structure of the sheath.
