Abstract
This utility model belongs to medical instruments field, the double-cavity negative-pressure drainage tube of the preposition sponge used under relating to scope.The double-cavity negative-pressure drainage tube of preposition sponge, is made up of spongy top and the double-cavity negative-pressure drainage tube be placed in spongy top; Described double-cavity negative-pressure drainage tube closes the outer tube of other end opening and the hollow bowl composition of both ends open primarily of one end; Inner tube length is greater than outer tube, and one end is placed in outer tube, but the two bottom does not contact; The other end stretches out outer tube; Outer tube wall has some conduction holes.The double-cavity negative-pressure drainage tube of the preposition sponge of this utility model can realize the constant drainage to inflammatory liquid, can solve vomica, around clean fistula mouth, also can promote that granulation generates, promote wound healing.
Description
Technical field
This utility model belongs to medical instruments field, the double-cavity negative-pressure drainage tube of the preposition sponge used under relating to scope.
Background technology
The cause of Enteral fistulas 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, and also can form peritoneal abscess, peritonitis in spill and leakage to abdominal cavity, rationally effective drain is the main method of infection control.
Existing negative-pressure drainage tube is generally made up of medium-hard macromolecular material, can be divided into be placed in in-house drain region with one or more conduction holes Drainage Section be positioned at beyond drain region for being connected Drainage Section and the Connectivity Section of pipeline providing negative pressure, Drainage Section and Connectivity Section are naturally continuous, and one end that both dissociate is respectively tail end and opening.The improvement of existing negative-pressure drainage tube is many based on accelerating drainage speed, preventing drainage tube from blocking, and as increased the conduction hole quantity of drainage tube, changing the shape of conduction hole, changing the cross section of Drainage Section.But the improvement of these structures all can not be avoided being sucked in conduction hole by the tissue of local when negative pressure value is higher in managing, cause the obstruction of conduction hole also may to tissue damage.And the general percutaneous of existing negative-pressure drainage tube is blind to be put, and can not look at fistula port area straight in put procedure, can only the later stage by imaging examination adjustment drainage tube position, with just to fistula mouth.In addition, used negative pressure drainage is realized by external vacuum pump, drainage tube and Lou Koudeng infected tissue region contact area little, best vacuum sealing state can not be reached, affect drainage effect.
Utility model content
The purpose of this utility model is the above-mentioned deficiency for prior art, the double-cavity negative-pressure drainage tube of the preposition sponge used under providing a kind of scope.
The purpose of this utility model realizes by following technical scheme:
A double-cavity negative-pressure drainage tube for preposition sponge, is made up of spongy top and the double-cavity negative-pressure drainage tube be placed in spongy top; Described double-cavity negative-pressure drainage tube closes the outer tube of other end opening and the hollow bowl composition of both ends open primarily of one end; Inner tube length is greater than outer tube, and one end is placed in outer tube, but the two bottom does not contact; The other end stretches out outer tube; Outer tube wall has some conduction holes.
Wherein, the other end of described hollow bowl stretches out outer tube, is connected with vacuum pump.
The preferably described outer wall of hollow bowl of the double-cavity negative-pressure drainage tube of described preposition sponge and the inwall spacing of outer tube be 0.3 ?0.6mm, hollow bowl and outer tube bottom apart 1.0 ?1.5cm.
Double-cavity negative-pressure drainage tube outer tube all embeds in spongy top.Spongy top is, according to wound surface size and the degree of depth, polyurethane sponge is pruned obtained by molding, and the exterior surface area of spongy top need be less than wound surface area.
Beneficial effect:
The trocar sheath end of this negative-pressure drainage tube is enclosed construction, and all side opening, all among sponge, makes the pressure distribution in drainage process in drainage tube even, ensures the even drain at wound surface place, improve drainage effect and therapeutic effect.Further, by outer tube perforate, manage in built-in negative pressure drainage, keep inner and outer pipe air can be appointed across a certain distance to enter mutually unobstructedly.When intraperitoneal has intestinal juice, intestinal juice enters inner and outer pipes gap by from the conduction hole of trocar sheath, then absorbs by having pipe in negative pressure.When intraperitoneal no liquid, suction catheter aspirates the air entered from inner and outer pipes gap.Like this, Intraabdominal tissue, organ directly do not contact with having in negative pressure to manage, and unlikely generation tissue enters negative tube and is damaged.In addition, design meets scope and use, ensure the drainage tube placement that endoscope's direct-view is lower, efficiently solve the technical problem that the intestinal fistula drainage tube position that exists in prior art is not good.
The double-cavity negative-pressure drainage tube of the preposition sponge of the present invention can realize the constant drainage to inflammatory liquid, can solve vomica, around clean fistula mouth, also can promote that granulation generates, promote wound healing.

Detailed description of the invention
Embodiment 1
The double-cavity negative-pressure drainage tube (Fig. 1) of a kind of preposition sponge, is made up of spongy top 1 and the double-cavity negative-pressure drainage tube 2 be placed in spongy top 1.Double-cavity negative-pressure drainage tube, the hollow bowl 4 of the outer tube 3 and both ends open of closing other end opening by one end forms; Interior pipe 4 length is greater than outer tube 3, and one end is placed in outer tube 3, but the two bottom does not contact; The other end stretches out outer tube 3; Outer tube 3 tube wall has some conduction holes 5.The outer wall of interior pipe 3 and the inwall spacing of outer tube 4 are 0.4mm, and interior pipe 3 and outer tube 4 bottom are at a distance of 1.0cm.When intraperitoneal has intestinal juice, the hole via spongy top 1 is entered inner and outer pipes gap by intestinal juice from the conduction hole 5 of trocar sheath, then absorbs by having pipe in negative pressure.When intraperitoneal no liquid, suction catheter aspirates the air entered from inner and outer pipes gap.
Drainage tube has one end per nasal of spongy top to insert, and per os inserts gastroscope, and foreign body forceps inserts operating gastroscope hole, and clamp sponge is together with around drainage tube to fistula mouth and vomica thereof.In drainage tube, the other end of pipe connects negative pressure, regulates vacuum pump to produce the pressure durations drain of 100-125mmHg.If vomica is comparatively large, the drainage tube of 2 preposition sponges can be used.
