Abstract
A device for aspirating fluids from a body cavity or hollow organ. The device includes an elongated tube having a proximal opening adapted to be coupled to a suctioning device. The elongated tube also has a portion spaced from the proximal opening to be positioned in the cavity or organ. The portion is convolved about a central axis and has at least one aspirating port facing inwardly of the convolved portion for spacing the at least one aspirating port from the walls of the cavity or organ.
Claims15
A nasogastric tube, comprising:
- an elongated tube having a proximal opening adapted to be coupled to a suctioning device;
- the elongated tube further having a distal portion spaced axially from the proximal opening and adapted to be positioned in the stomach;
- the distal portion of the elongated tube being formed in an elongated helix having one or more aspirating ports, all of said aspirating ports facing inwardly of the helical portion for spacing such ports from the gastric mucosa.
A device for aspirating fluids from a body cavity or hollow organ, comprising:
- an elongated tube having a proximal opening adapted to be coupled to a suctioning device;
- the elongated tube having a portion spaced from the proximal opening to be positioned in the cavity or organ;
- the portion being formed in an elongated helix having one or more aspirating ports, all of said aspirating ports facing inwardly of the helical portion for spacing such ports from the walls of the cavity or organ.
A method of aspirating fluid from a body cavity or hollow organ, comprising:
- positioning a distal portion of an elongated tube in said body cavity or hollow organ, the distal portion being formed in an elongated helix having one or more aspirating ports facing inwardly of the helical portion for spacing such ports from the walls of the cavity or organ;
- the helically formed distal portion having an outwardly facing surface lacking aspirating ports such that body tissue coming in contact with said outwardly facing surface is not subjected to suction applied to the interior of the elongated tube;
- coupling a suctioning device to a proximal end of the elongated tube;
- and
- applying suction to the proximal end of the elongated tube.
