Feeding tube aperture

Abstract

A feeding tube aperture supported and aligned with a feeding tube opening in an abdominal wall of a patient, including a base having a first end surface transverse to an axis of the base and a feeding tube, a second opposed end surface, a central feeding tube passage extending between the first and second end surfaces, a plurality of vent passages around the feeding tube passage and extending between the first and second end surfaces, a hollow, cylindrical feeding tube support extension centered on and extending outwardly from the feeding tube passage to support and align the feeding tube aperture, and a plurality of spaced apart resilient spacers extending outwards from the second end surface. The plurality of spaced apart resilient spacers resiliently space the second end surface from the abdominal wall and form a plurality of air passages to allow a flow of air around the abdominal wall and the feeding tube opening.

What is claimed is: 
     
       1. A feeding tube aperture positionable at an external abdominal wall of a patient and along a feeding tube extending through the abdominal wall of the patient to support and align the feeding tube with a feeding tube opening through the abdominal wall of the patient, comprising:
 a base having
 a circumferential surface symmetric about an axis, 
 a first end surface transverse to the axis, 
 a second end surface transverse to the axis and facing in an axially opposite direction from the first end surface, 
 a centrally located feeding tube passage extending along the axis and through the base from the first end surface to the second end surface and having an interior diameter accommodating the feeding tube in a slidable frictional engagement between the feeding tube and an interior surface of the feeding tube passage, 
 a plurality of large axial vent passages occupying a region between the centrally located feeding tube passage and the circumferential surface and extending through the base from the first end surface to the second end surface with the plurality of large axial vent passages being disposed symmetrically around the centrally located feeding tube passage, 
 
 a hollow, cylindrical feeding tube support extension extending outwardly from the first end surface and axially centered on the axis with an interior diameter accommodating the feeding tube in a slidable frictional engagement between the feeding tube and an interior surface of the feeding tube support extension, and 
 a plurality of resilient spacers attached to a circumference of the second end surface and extending outward from the second end surface, the plurality of resilient spacers being spaced circumferentially apart around the circumference of the second end surface with a longitudinal axis of each of the plurality of resilient spacers extending generally along the circumference of the second end surface, so that
 when the feeding tube aperture is mounted onto the feeding tube with the second end surface oriented toward and directly adjacent the abdominal wall with the plurality of resilient spacers in contact with the abdominal wall,
 the feeding tube aperture is resiliently spaced from the abdominal wall by the plurality of resilient spacers, and 
 the plurality of resilient spacers form a common air space located between the second end surface and the abdominal wall, the air space extending from the centrally located feeding tube passage to the circumference of the second end surface and communicating with each of the plurality of large axial vent passages and with each of a plurality of circumferential vent passages formed between adjacent pairs of the plurality of resilient spacers, so that the plurality of large axial vent passages through the base, the air space between the second end surface and the abdominal wall and the plurality of circumferential vent passages allow a flow of air around the abdominal wall and the feeding tube opening in the abdominal wall during use. 
 
 
 
     
     
       2. The feeding tube aperture of  claim 1 , further comprising:
 a circumferential flange located on the circumference of the second end surface and extending outwards from the second end surface, wherein 
 each of the plurality of resilient spacers comprises a generally cylindrical hollow tube of resilient foam with a longitudinal opening in a wall of the generally cylindrical hollow tube extending lengthwise along the longitudinal axis of each of the plurality of resilient spacers, and 
 each of the plurality of resilient spacers is attached to the feeding tube aperture by mounting each of the resilient spacers at a selected location on a circumference of the circumferential flange with a first side of the longitudinal opening bearing against the base in a region of the circumferential surface of the base and an adjoining surface of the circumferential flange and a second side of the longitudinal opening bearing against the second end surface of the base. 
 
     
     
       3. The feeding tube aperture of  claim 1 , further comprising:
 a circumferential flange located on the circumference of the second end surface and extending outwards from the second end surface, wherein 
 each of the plurality of resilient spacers comprises a generally cylindrical hollow tube of resilient foam having a longitudinal opening formed in a wall of the generally cylindrical hollow tube, and 
 each of the plurality of resilient spacers is attached to the feeding tube aperture via engagement of the longitudinal opening with the circumference of the second end surface. 
 
     
     
       4. A medical tube aperture positionable at skin of a patient and along a medical tube extending through the skin of the patient to support and align the medical tube with a medical tube opening through the skin of the patient, comprising: a base having a circumferential surface symmetric about an axis, a first end surface transverse to the axis, a second end surface transverse to the axis and facing in an axially opposite direction from the first end surface, a centrally located medical tube passage extending along the axis and through the base from the first end surface to the second end surface and having an interior diameter accommodating the medical tube in a slidable frictional engagement between the medical tube and an interior surface of the medical tube passage, a plurality of large axial vent passages occupying a region between the centrally located medical tube passage and the circumferential surface and extending through the base from the first end surface to the second end surface with the plurality of large axial vent passages being disposed symmetrically around the centrally located medical tube passage, a hollow, cylindrical medical tube support extension extending outwardly from the first end surface and axially centered on the axis with an interior diameter accommodating the medical tube in a slidable frictional engagement between the medical tube and an interior surface of the medical tube support extension, and a plurality of resilient spacers attached to a circumference of the second end surface and extending outward from the second end surface, the plurality of resilient spacers being spaced circumferentially apart around the circumference of the second end surface with a longitudinal axis of each of the plurality of resilient spacers extending generally along the circumference of the second end surface, so that when the medical tube aperture is mounted onto the medical tube with the second end surface oriented toward and directly adjacent the skin with the plurality of resilient spacers in contact with the skin, the medical tube aperture is resiliently spaced from the skin by the plurality of resilient spacers, and the plurality of resilient spacers form a common air space located between the second end surface and the skin, the air space extending from the centrally located medical tube passage to the circumference of the second end surface and communicating with each of the plurality of large axial vent passages and with each of a plurality of circumferential vent passages formed between adjacent pairs of the plurality of resilient spacers, so that the plurality of large axial vent passages through the base, the air space between the second end surface and the skin and the plurality of circumferential vent passages allow a flow of air around the skin and the medical tube opening in the skin during use.
