Abstract

A gastrostomy feeding port includes a deformable, conical tip portion having at least one side aperture therethrough, a tube portion which extends rearwardly from the tip portion, a fitting portion on the rear end of the tube portion, a removable valve portion in the fitting portion and a flange portion which extends outwardly from the fitting portion. The feeding port is adapted to be installed in a patient so that the tube portion extends through a preestablished stoma in the patient'"'"'s stomach with the tip portion located in the patient'"'"'s stomach and the fitting portion and the flange portion engaging the skin of the patient adjacent the stoma. Since the valve portion is removable received in the fitting portion, it can be repaired or replaced if needed without replacing the entire feeding port.

Claims

2. In the gastrostomy feeding port of claim 1, said tip portion being of hollow conical configuration and being deformable to pass said tip portion through said stoma.

3. In the gastrostomy feeding port of claim 1, said valve portion being threadedly received in said fitting portion.

4. In the gastrostomy feeding port of claim 1, said valve portion comprising duck-bill type valve.

5. The gastrostomy feeding port of claim 1 further comprising means biasing on said tip portion biasing the latter against the inner side of the stomach wall of said patient.

6. In the gastrostomy feeding port of claim 5, said biasing means comprising an outwardly extending concave flange on said fitting portion facing toward said tip portion, said flange being resiliently deformable and being engageable with the skin of said patient adjacent said stoma for biasing said tip portion against the inner wall of the patient'"'"'s stomach.

7. In the gastrostomy feeding port of claim 1, said valve portion being removably received in said fitting portion. PG,16

8. A gastrostomy feeding port comprising a tip portion, a tube portion, a fitting portion and a valve portion, said tip portion being receivable through a preestablished stoma in the stomach of a patient and being operative for passing a fluid into said stomach, said tip portion including retaining means engageable with the inner wall of said stomach for preventing the inadvertent removal of said feeding port from said stoma, said tube portion communicating with said tip portion for passing said fluid thereto and extending rearwardly therefrom, said tube portion being dimensioned to extend outwardly through said stoma when said tip portion is in engagement with the inner wall of the stomach of said patient, said fitting portion being of a low-profile configuration and being attached to the rear end of said tube portion so that said fitting portion is disposed substantially on the exterior of said patient adjacent the skin surrounding said stoma when said tip portion is in engagement with said inner stomach wall, said valve portion being removably received in said fitting portion and being accessible from the exterior of said patient, said valve portion being operative for permitting the flow of a feeding formula into said tube portion from said fitting portion and for preventing the reverse flow of said feeding formula.

9. In the gastrostomy feeding port of claim 8, said tip portion being of hollow conical configuration and being deformable to pass said tip portion through said stoma.

10. In the gastrostomy feeding port of claim 8, said valve portion being threadedly received in said fitting portion.

11. In the gastrostomy feeding port of claim 8, said valve portion comprising a duck-bill type valve.

12. The gastrostomy feeding port of claim 8 further comprising means biasing on said tip portion biasing the latter against the inner side of the stomach wall of said patient.

13. In the gastrostomy feeding port of claim 12, said biasing means comprising an outwardly extending concave flange on said fitting portion facing toward said tip portion, said flange being resiliently deformable and being engageable with the skin of said patient adjacent the stoma for biasing said tip portion against the tinner wall of the patient'"'"'stomach.
