Abstract

A low profile gastrostomy feeding device having a bolster portion, a balloon member, and tubular member extending between the bolster portion and the balloon member. The bolster portion includes an anti-reflux valve, a closure member, an inflation valve housing, and a cap retainer portion. An inflation lumen and a feeding lumen are provided by the tubular member. The inflation lumen curves as it passes through the bolster portion from the tubular member to the inflation housing.

Claims

1. A gastrostomy feeding device comprising a bolster portion, a balloon member, and a tubular member extending between said bolster portion and said balloon member, said tubular member and bolster portion cooperating to define an inflation passage and a feeding passage, said inflation and feeding passages extending through said tubular member generally parallel one another and to a longitudinal axis of said tubular member, said bolster portion comprising an anti-reflux valve, an inflation valve housing, a receptacle, and a feeding port, said inflation valve housing receiving an inflation valve and being in fluid communication with said balloon member via said inflation lumen, said receptacle receiving a locking cap member, said cap member being disposed relatively between said feeding port and said anti-reflux valve, wherein said inflation lumen curves as it extends through said bolster portion from said tubular member toward said inflation valve housing to maintain a generally constant thickness of material between said inflation lumen and said receptacle to reduce distortion of the inflation passage by forces applied to the cap member, and wherein said bolster portion further includes a closure member, said closure member having a first end secured to the bolster portion and a second end including a plug which is received within the cap member.

2. A gastrostomy feeding device according to claim 1, further comprising a feeding adaptor, wherein said cap member defines a keyway and said feeding adaptor defines a key, said feeding adaptor key being received within and removably locked to said keyway in a twist-and-lock fashion.

3. A gastrostomy device according to claim 1, wherein said receptacle is provided by a cap retainer portion of said bolster portion, said receptacle being defined by a pair of annular wall surfaces and a radial wall, said radial wall surrounding and corresponding to at least a portion of said cap member.

4. A gastrostomy device according to claim 3, wherein said radial wall includes an annular wall portion and a frustoconical wall portion, said annular wall portion defining a cylindrical space and said frustoconical wall portion extending downwardly from said annular wall portion.

5. A gastrostomy device according to claim 4, wherein an annular seal member is disposed relatively beneath said frustoconical wall portion, said seal member defining a lower extent of said receptacle.

6. A gastrostomy device according to claim 5, wherein said cap retainer portion includes an outer wall, said outer wall being penetrated by an opening, said outer wall defining an upper limit of said receptacle.

7. A gastrostomy device according to claim 6, wherein said anti-reflux valve is located vertically adjacent said seal member.

8. A gastrostomy device according to claim 7, wherein said anti-reflux valve is integrally formed with the bolster portion and includes a plurality of flexible arms.

9. A gastrostomy feeding device comprising a bolster portion, a balloon member, and a tubular member extending between said bolster portion and said balloon member, said tubular member and bolster portion cooperating to define an inflation passage and a feeding passage, said inflation and feeding passages extending through said tubular member generally parallel one another and to a longitudinal axis of said tubular member, said bolster portion comprising an anti-reflux valve, an inflation valve housing, a receptacle, and a feeding port, said inflation valve housing receiving an inflation valve and being in fluid communication with said balloon member via said inflation lumen, said receptacle receiving a locking cap member, said cap member being disposed relatively between said feeding port and said anti-reflux valve, wherein the cap member comprises upper and lower ring-shaped wall members that are joined by a cylindrical interconnecting wall, said upper and lower ring-shaped wall members extending radially outward farther than said cylindrical interconnecting wall;

wherein said receptacle is defined at least in part by a radial wall surrounding and corresponding to at least a portion of said cap member, said radial wall including an annular wall portion and a frustoconical wall portion, said annular wall portion defining a cylindrical space and said frustoconical wall portion extending downwardly from said annular wall portion;

wherein said gastrostomy device further comprises an annular seal member disposed relatively beneath said frustoconical wall portion, said seal member defining a lower extent of said receptacle;

wherein said anti-reflux valve is located vertically adjacent said seal member;

wherein said cap retainer portion includes an outer wall, said outer wall being penetrated by an opening, said outer wall defining an upper extent of said receptacle;

wherein said bolster portion further includes a closure member, said closure member having a first end secured to the bolster portion and a second end including a plug which is received within the cap member; and

wherein said gastrostomy feeding device further comprises a feeding adaptor, wherein said cap member defines a keyway and said feeding adaptor defines a key, said feeding adaptor key being received within and removably locked to said keyway in a twist-and-lock fashion.

10. A gastrostomy feeding device comprising a bolster portion, a balloon member, a feeding adaptor, and a tubular member extending between said bolster portion and said balloon member, said tubular member and said bolster portion cooperating to define an inflation passage and a feeding passage, said inflation and feeding passages extending through said tubular member generally parallel one another and to a longitudinal axis of said tubular member, said bolster portion comprising an anti-reflux valve, an inflation valve housing, a receptacle, an annular seal member, and a feeding port, said inflation valve housing receiving an inflation valve and being in fluid communication with said balloon member via said inflation lumen, said receptacle receiving a locking cap member, said cap member being disposed relatively between said feeding port and said anti-reflux valve, wherein said anti-reflux valve is integrally formed with said bolster portion and comprises a plurality of flexible arm members, and wherein said seal member is disposed relatively between said cap member and said anti-reflux valve, and wherein said cap member defines a keyway and said feeding adaptor comprises a key, said feeding adaptor key being received within and removably locked to said cap member keyway in a twist-and-lock fashion.

11. A gastrostomy feeding device according to claim 10, wherein said feeding adaptor comprises a dispensing portion which is adapted to extend through said cap member and beyond said anti-reflux valve and into said tubular member, said dispensing portion defining an annular groove which sealing receives said seal member.
