Abstract
本实用新型属于医疗器械领域，涉及一种双腔负压引流管。一种双腔负压引流管，主要由一端封闭另一端开口的外管和两端开口的中空内管组成；内管长度大于外管，一端置于外管内，但二者底端不接触；另一端伸出外管；外管管壁开有若干引流孔。当腹腔内有肠液时，肠液将从外套管的引流孔中进入内外管间隙，再由具有负压的内管吸除。当腹腔内无液体时，吸引管抽吸自内外管间隙进入的空气。这样，腹腔内的组织、器官不与具有负压的内管直接接触，不致发生组织进入负压管而被损伤。
The utility model belongs to the field of medical equipment and relates to a double-cavity negative pressure drainage tube. A double-chamber negative pressure drainage tube, mainly composed of an outer tube with one end closed and the other end open, and a hollow inner tube with both ends open; the inner tube is longer than the outer tube, and one end is placed in the outer tube, but the bottom ends of the two do not touch; The other end protrudes from the outer tube; the wall of the outer tube is provided with a number of drainage holes. When there is intestinal fluid in the peritoneal cavity, the intestinal fluid will enter the space between the inner and outer tubes from the drainage hole of the outer tube, and then be sucked out by the inner tube with negative pressure. When there is no fluid in the abdominal cavity, the suction tube sucks the air that enters from the space between the inner and outer tubes. In this way, the tissues and organs in the abdominal cavity are not in direct contact with the inner tube with negative pressure, so that the tissue will not enter the negative pressure tube and be damaged.
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.
