  • Publication number: 20100076383
    Abstract: A low profile adaptor for use with a medical catheter. In one embodiment, the adaptor comprises a lower connector portion, an upper connector portion and a valve. The lower connector portion comprises a tubular portion and an annular portion, the annular portion radially surrounding the tubular portion along an intermediate length thereof. A helical thread is formed on the inside surface of the tubular portion. A circular lip projects upwardly a short distance from the top surface of the annular portion. The upper connector portion comprises a tubular section adapted for insertion into the tubular portion of the lower connector portion. An external helical thread is formed on the tubular section of the upper connector portion for mating engagement with the thread on the interior of the tubular portion of the lower connector portion. The upper connector portion also includes an annular base.

  • Patent number: 6976980
    Abstract: Low profile adaptor for use with gastrostomy feeding tube. In a preferred embodiment, the adaptor comprises a disc-shaped housing, the housing being provided with a bottom opening and a side slot, the side slot having a uniform width, except for an enlarged area at one end thereof. A tube is disposed within the housing, the tube having a first end, a second end, and a longitudinal bore. The first end is aligned with the bottom opening and is adapted to be inserted into the proximal end of a gastrostomy feeding tube. A ratchet-type clamp is disposed within the housing and is used to secure the gastrostomy feeding tube to the first end of the tube. A lateral slot is formed in the tube at its second end and is in fluid communication with the longitudinal bore. A dial is disposed within the housing and is rotatably mounted on the second end of the tube, the dial including a radial channel.

  • Patent number: 6814716
    Abstract: A device for externally retaining a gastrostomy feeding tube comprises a clip. In one embodiment, the clip is a generally rectangular, unitary structure shaped to include a first end wall, a second end wall spaced apart from and extending parallel to the first end wall, a lower wall extending perpendicularly between and interconnecting the first end wall and the second end wall, and an upper wall having a first end connected to the first end wall and a second end spaced apart from the second end wall. The first end wall, the second end wall, the lower wall and the upper wall together define a tubing storage cavity, with the space between the upper wall and the second end wall defining an inlet to the tubing storage cavity. The first end wall has a top surface, a bottom surface and a bore extending between said top surface and said bottom surface.
