Description
Technical field
The utility model relates to a kind of negative-pressure drainage tubes, more particularly to a kind of integrated negative-pressure drainage tube.
Background technique
Existing medical drainage tube is generally used for surgical operation, will be gathered between tissue or in body cavity by drainage tube
Purulence, blood and liquid etc. are drained in vitro, to prevent postoperative infection and influence wound healing.And existing some drainage tubes use
Double-deck pipe body structure need to be converted to transfer tube hydrops being transported to collection device when drainage tube drains into human external.In this way
The end of drainage tube needs transfer tube of plugging into, not only time-consuming and laborious to connection between the two, but also there is the risk loosened, makes
At the leakage of hydrops, to influence the implementation of surgical operation.
Utility model content
In order to overcome the deficiencies of the prior art, the purpose of this utility model is to provide one kind without separately plugging into, integration
Molding negative-pressure drainage tube.
The utility model is that technical solution used by solving the problems, such as it is:
A kind of integration negative-pressure drainage tube, including outer tube and inner tube, said inner tube end are gradually increased and extend to outer tube
Tube wall, said inner tube and outer tube are integrally formed, said inner tube connection outer tube supported on both sides, and said inner tube is equipped with conduction hole, institute
Outer tube is stated equipped with two drainage seams, the drainage seam is symmetricly set on outer tube, and the thickness of the outer tube draws from separate respectively
It gradually narrows to drainage seam the position of stream seam.
Further, said inner tube two sides are parallel to each other towards the tube wall of drainage seam.
Further, plane where said inner tube tube wall is stitched with drainage is perpendicular.
Further, said inner tube is equipped with multiple conduction holes along the axial uniformly arrangement of inner tube, the position of the conduction hole
It is corresponding with the position of drainage seam.
Further, the drainage seam is axially extended straight along outer tube.
The beneficial effects of the utility model are: a kind of integrated negative-pressure drainage tube that the utility model uses, interior pipe end
It is gradually increased and extends to outer tube wall, inner and outer tubes are integrally formed, and pipe end interior so directly postpones to outer tube wall simultaneously
It attaches integrally, becomes the pipe structure of single layer, convenient for transmitting the hydrops for draining and, without additional transmission of separately plugging into
Pipe, also avoids the risk leaked.In addition, inner tube is directly connected with outer tube, and the pipe walls support outer tube of inner tube two sides, knot
Structure is stablized, and supporting surface is big, and support force foot not only takes full advantage of the space of outer tube, thus accelerate drainage speed, Er Qie
Tube body is not easy to collapse during drainage is shunk, and prevents clogging, guarantees drainage effect.
Detailed description of the invention
Fig. 1 is that the inner tube of the utility model extends to outer tube part structural schematic diagram；
Fig. 2 is the cross section structure schematic diagram of the utility model；
Figure label: 1- outer tube；2- inner tube；3- conduction hole；4- drainage seam.
Specific embodiment
The utility model is described in further detail with example with reference to the accompanying drawing.
As shown in Figs. 1-2, the utility model provides a kind of integrated negative-pressure drainage tube, including outer tube 1 and inner tube 2, inner tube 2
End is gradually increased and extends to 1 tube wall of outer tube, and inner tube 2 and outer tube 1 are integrally formed, and the connection outer tube 1 supported on both sides of inner tube 2 is interior
Pipe 2 is equipped with conduction hole 3, and outer tube 1 is equipped with two drainage seams 4, and drainage seam 4 is symmetricly set on outer tube 1, the thickness of outer tube 1
It gradually narrows from the position far from drainage seam 4 to from drainage seam 4 respectively, so that the tube body and drainage seam 4 close to drainage seam 4 are formed
Valve structure.2 end of inner tube is directly postponed to 1 inner wall of outer tube and is attached integrally, and the pipe structure of single layer is become, convenient for transmission
It drains the hydrops taken and also avoids the risk leaked without additional transfer tube of separately plugging into.Inner tube 2 is directly and outside
Pipe 1 is connected, and the pipe walls support outer tube 1 of 2 two sides of inner tube, stable structure not only take full advantage of the space inside outer tube 1,
To accelerate drainage speed, and tube body is not easy to collapse during draining contraction, prevents clogging.
In the present embodiment, in order to guarantee the optimum efficiency of drainage, 2 two sides of inner tube are parallel to each other towards the tube wall of drainage seam 4,
2 tube wall of inner tube and drainage 4 place planes of seam are perpendicular.
Inner tube 2 is equipped with multiple conduction holes 3 along the axial uniformly arrangement of inner tube 2, the position of conduction hole 3 and the position of drainage seam 4
It sets relatively, drainage speed can be accelerated in this way.
Drainage seam 4 is axially extended straight along outer tube 1.
When it is implemented, negative-pressure drainage tube is inserted into human body, make to generate negative pressure in tube body by external negative pressure device, negative
It opens drainage seam 4 under pressure effect, the intracorporal hydrops of people is drained to by drainage seam 4 and conduction hole 3 to human external, thus
The process of drainage is completed, and stops 4 closure of drainage seam when negative pressure drainage.
The negative-pressure drainage tube in vivo using the double-deck pipe body structure of outer tube 1 and inner tube 2 be convenient for drawing hydrops by section；And
External section becomes single layer pipe structure, since 2 end of inner tube is directly postponed to 1 inner wall of outer tube and is attached integrally convenient for transmission
Hydrops, without additional transfer tube of separately plugging into.
The above, the only preferred embodiment of the utility model, the utility model are not limited to above-mentioned implementation
Mode, as long as its technical effect for reaching the utility model with identical means, all should belong to the protection scope of the utility model.
