Abstract
The utility model discloses a gastric lavage tube which comprises an outer tube and an inner tube. The tail ends of the outer tube and the inner tube are blind ends. A partition wall is arranged in the inner cavity of the tail-end part of the outer tube, and the partition wall divides the inner cavity of the outer tube into a liquid feed chamber and a liquid suction chamber. A liquid feed hole is formed on the wall of the outer tube corresponding to the liquid suction chamber. A liquid discharge hole is formed on the wall of the outer tube corresponding to the liquid feed chamber. The inner tube is sleeved in the inner cavity of the outer tube by passing through the partition wall. A liquid suction hole is formed on the wall of the inner tube inside the liquid feed chamber. The liquid feed hole and the liquid suction hole are in staggered arrangement. The gastric lavage tube is not easy to block.
Description
Technical field
This utility model relates to a kind of gastrolavage tube.
Background technology
At present, the gastrolavage tube that hospital uses is the single tube structure, and the gastrolavage tube of this single tube structure is easily stopped up by the chyme residue of gastric and liquid food when gastric lavage, incurs loss through delay the opportunity of gastric lavage, influences the efficient of gastric lavage, and then the success rate of influence rescue.
The utility model content
The technical problems to be solved in the utility model is at above-mentioned deficiency, and a kind of not susceptible to plugging gastrolavage tube is provided.
In order to solve the problems of the technologies described above, this utility model provides a kind of gastrolavage tube of following structure, this gastrolavage tube comprises outer tube and interior pipe, the end of outer tube and interior pipe is a cecum, be provided with partition in the inner chamber of the terminal part section of outer tube, partition is partitioned into admission chamber and imbibition chamber to the inner chamber of outer tube, the tube wall of the outer tube corresponding with the imbibition chamber is provided with inlet opening, the tube wall of the outer tube corresponding with admission chamber is provided with liquid outlet, interior pipe passes partition and is sleeved in the outer tube bore, the tube wall that is positioned at the pipe of imbibition intracavity is provided with imbibing hole, and inlet opening and imbibing hole shift to install.
The gastrolavage tube of said structure, owing to adopt inside and outside two-layer pipe, the imbibing hole hole on the inner pipe wall corresponding with the imbibition chamber of the inlet opening on the outer tube wall of imbibition chamber correspondence shifts to install, thereby gastrolavage tube provided by the utility model is difficult for obstruction.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Gastrolavage tube as shown in drawings, this gastrolavage tube comprises outer tube 1 and interior pipe 2, the end of outer tube 1 and interior pipe 2 is a cecum, be provided with partition 3 in the inner chamber of the terminal part section of outer tube 1, partition 3 is partitioned into admission chamber 4 and imbibition chamber 5 to the inner chamber of outer tube 1, the tube wall of the outer tube 1 corresponding with imbibition chamber 5 is provided with inlet opening 6, the tube wall of the outer tube 1 corresponding with admission chamber 4 is provided with liquid outlet 7, interior pipe 2 passes partition 3 and is sleeved in outer tube 1 inner chamber, the tube wall that is positioned at the pipe 2 in imbibition chamber 5 is provided with imbibing hole 8, and it is that inlet opening 6 is not corresponding with imbibing hole 8 positions that inlet opening 6 shifts to install with imbibing hole 8.Imbibing hole 8 and inlet opening 6 are preferably irregularly shaped, and for example tri-angle-holed, polygonal hole etc. so more help preventing stopping up.
During use, the gastrolavage tube of said structure is connected with paunch flusher, liquid of gastric lavage flows into and is ejected into gastric through liquid outlet 7 from admission chamber 4, and the liquid of gastric enters imbibition chamber 5 and in imbibing hole 8 flows into pipe 2 inner chambers, again by interior pipe 2 discharges through inlet opening 6.
