Abstract
The utility model belongs to the field of medical instruments and relates to a two-cavity negative pressure drainage tube. The two-cavity negative pressure drainage tube is mainly composed of an outer tube and a hollow inner tube, wherein one end of the outer tube is closed and the other end of the outer tube is opened, and the two ends of the hollow inner tube are opened. The length of the inner tube is larger than that of the outer tube. One end of the inner tube is arranged in the outer tube, but the bottom end of the inner tube and the bottom end of the outer tube do not make contact. The other end of the inner tube extends out of the outer tube. A plurality of drainage holes are formed in the wall of the outer tube. When intestinal juices exist in the abdominal cavity, the intestinal juices enter the gap between the inner tube and the outer tube from the drainage holes of the outer tube, and sucked out by the inner tube with negative pressure. When the intestinal juices do not exist in the abdominal cavity, the inner tube sucks air entering from the gap between the inner tube and the outer tube. Therefore, tissue and organs in the abdominal cavity do not directly make contact with the inner tube with the negative pressure and the situation that the tissue enters the inner tube with the negative pressure and are damaged can not happen.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of two-chamber negative-pressure drainage tube.
Background technology
The cause of the outer fistula of intestinal is the excessive of fistula oral area intestinal juice.Excessive intestinal juice not only can corrode to be organized and abdominal skin in fistula week, but also spill and leakage to abdominal cavity forms peritoneal abscess, peritonitis, and the rational and effective drain is the main method of control infection.
Existing negative-pressure drainage tube is generally made by medium-hard macromolecular material, be used to be connected the Drainage Section and the Connectivity Section that the pipeline of negative pressure is provided beyond can being divided into the Drainage Section that places in-house drain zone to have one or more conduction holes and being positioned at the drain zone, Drainage Section and Connectivity Section are continuous naturally, and both are respectively tail end and opening by a free end.The improvement of existing negative-pressure drainage tube is based on accelerating drainage speed more, is prevented that drainage tube from blocking, and as increasing the conduction hole quantity of drainage tube, changes the shape of conduction hole, changes the cross section of Drainage Section.But the improvement of these structures can not avoid all that negative pressure value sucks partial tissue in the conduction hole when higher in pipe, causes the obstruction of conduction hole also may cause damage to tissue.
The utility model content
The purpose of this utility model is that the above-mentioned defective at prior art provides a kind of two-chamber negative-pressure drainage tube.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of two-chamber negative-pressure drainage tube mainly is made up of the outer tube of end sealing other end opening and the hollow bowl of both ends open; Interior length of tube is greater than outer tube, and an end places in the outer tube, but the two bottom does not contact; The other end stretches out outer tube; Outer tube wall has some conduction holes.
In described the inwall spacing of outer wall and the outer tube of pipe be preferably 0.3 ?0.6mm, interior pipe and outer tube bottom preferably apart 1.0 ?1.5cm.
Preferred as another kind of the present utility model, the outer wall of being close to outer tube is provided with the hollow weep pipe of a both ends open.
Beneficial effect:
This utility model is managed in the built-in negative pressure drainage by in the outer tube perforate, keeps inner and outer pipe can appoint air to enter across a certain distance mutually unobstructedly.When intraperitoneal has intestinal juice, intestinal juice will enter the inner and outer pipes gap from the conduction hole of trocar sheath, be absorbed by the interior pipe with negative pressure again.When the intraperitoneal no liquid, the air that the suction catheter suction enters from the inner and outer pipes gap.Like this, Intraabdominal tissue, organ directly do not contact with the interior pipe with negative pressure, and unlikely generation tissue enters the negative pressure pipe and is damaged.Contain mucus, protein substance in the intestinal juice, under the situation of continuous suction air, will condense into crust and stop up conduction hole, reduce the effect of drainage tube.Preferred as another kind of the present utility model, by a weep pipe being set being close to outer tube outer wall, continue to splash into isotonic saline solution, every day 3000 ?4000ml, prevent that mucus, protein substance from condensing into crust and stopping up conduction hole, to keep the unobstructed of two-chamber negative-pressure drainage tube.

The specific embodiment
A kind of two-chamber negative-pressure drainage tube (Fig. 1) is made up of the outer tube 2 of end sealing other end opening and the hollow bowl 1 of both ends open; Interior pipe 1 length places in the outer tube 2 greater than outer tube 2, one ends, but the two bottom does not contact; The other end stretches out outer tube 2; Outer tube 2 tube walls have some conduction holes 3.The outer wall of interior pipe 1 and the inwall spacing of outer tube 2 are 0.4mm, and interior pipe 1 and outer tube 2 bottoms are at a distance of 1.0cm.When intraperitoneal has intestinal juice, intestinal juice will enter the inner and outer pipes gap from the conduction hole of trocar sheath, be absorbed by the interior pipe with negative pressure again.When the intraperitoneal no liquid, the air (Fig. 2) that the suction catheter suction enters from the inner and outer pipes gap.
This utility model drainage tube is used for the drain of the outer fistula fistula oral area intestinal juice of intestinal, in order to guarantee the unobstructed of negative-pressure drainage tube, remove after drainage tube is placed 4d, fistula has begun to take shape under the ground situation, duty is changed mozzle, purpose be to make on the drainage wall aperture not with fistula in granulation tissue adhesion.Should change every day later on outside 1 drainage tube, also should when placing drainage tube, follow the catheter of putting into F12 ?14 to continue to splash into isotonic saline solution, every days 3000 ?4000ml, purpose not only is to wash vomica but keeps the unobstructed of suction catheter.Contain mucus, protein substance in the intestinal juice, under the situation of continuous suction air, will condense into crust and stop up drainage tube, reduce the effect of drainage tube.
A kind of two-chamber negative-pressure drainage tube (Fig. 3) is made up of the outer tube 2 of end sealing other end opening and the hollow bowl 1 of both ends open; Interior pipe 1 length places in the outer tube 2 greater than outer tube 2, one ends, but the two bottom does not contact; The other end stretches out outer tube 2; Outer tube 2 tube walls have some conduction holes 3.The outer wall of interior pipe 1 and the inwall spacing of outer tube 2 are 0.5mm, and interior pipe 1 and outer tube 2 bottoms are at a distance of 1.5cm.The outer wall of being close to outer tube 2 is provided with the hollow weep pipe 4 of a both ends open, and realization can enter air, can continue to drip isotonic saline solution again.
