The inner tube mainly plays the drainage effect, and pushed down in, intraductal liquid as drainage tube and will be pushed to the outer tube in, and the wound that can not flow backwards back. Simultaneously, protective case forms a confined air cavity around the outer tube, play fine buffering and guard action.
Description
Technical field
This utility model relates to a kind of drainage tube.
Background technology
Drainage tube applies very general a kind of medical apparatus and instruments clinically, and its effect is directed to external by the pus gathered between tissue or in body cavity, blood, liquid, prevents postoperative infection, reduces local pressure, prevent adhesion, promotes wound healing.
Clinically at present, patient, when using drainage tube, note being pressed onto drainage tube in the moment, otherwise it is not smooth that drainage tube will be caused to circulate, and even causes liquid to flow back to wound.This adds increased the degree of patient's discomfort.Existing drainage tube is only a simple conduit, can not solve the problem.
Utility model content
For above-mentioned technical problem, this utility model provides the drainage tube of a kind of resistance to compression folding.
The technical scheme that this utility model provides is:
A kind of drainage tube, comprising:
Interior pipe, its front end is insertable part, and the middle part of described interior pipe offers the side opening that diameter is 1mm, and the front end of described interior pipe has conduction hole, and rear end is unlimited;
Outer tube, it is sheathed on the outside of the middle part of described interior pipe, and the front end of described outer tube is connected with the outer wall of described interior pipe, thus makes the front end of described outer tube be closed state, and the rear end of described outer tube is unlimited; And
Protective casing, it is set in the outside of described outer tube, and the front end of described protective casing is connected with the front end of described outer tube, and the rear end of described protective casing is connected with the outer wall of the rear end of described outer tube, to form an air cavity closed in the outside of described outer tube.
Preferably, in described drainage tube, the tube wall of described protective casing is outwardly formed with multiple air chamber, communicates with each other between described air chamber and described air cavity.
Preferably, in described drainage tube, the locular wall of described air chamber is less at the thickness of tube wall of the part not forming air chamber than described protective casing.
Preferably, in described drainage tube, the thickness of the locular wall of described air chamber is 0.1mm, and described protective casing is 0.3mm at the thickness of tube wall of the part not forming air chamber.
Preferably, in described drainage tube, the tube wall lateral surface of described protective casing is evenly distributed with multiple air chamber, communicates with each other between air chamber.
Preferably, in described drainage tube, the thickness of described air chamber is 2 ~ 3mm.
Drainage tube described in the utility model comprises interior pipe, outer tube and protective casing, and outer tube sleeve is located at the outside of interior pipe, and interior pipe has insertable part; interior pipe mainly plays drainage; when drainage tube is held down, the liquid in interior pipe will be extruded in outer tube, and can not flow back to wound.Meanwhile, protective casing forms an air cavity closed around outer tube, plays good cushioning and protection.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of an embodiment of drainage tube described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail, can implements according to this with reference to description word to make those skilled in the art.
As shown in Figure 1, this utility model provides a kind of drainage tube, comprising: interior pipe 9, and its front end is insertable part 1, and the middle part 2 of described interior pipe offers the side opening 5 that diameter is 1mm, and the front end of described interior pipe has conduction hole, and rear end 7 is what open wide; Outer tube 3, it is sheathed on the outside of the middle part 2 of described interior pipe, and the front end of described outer tube 3 is connected with the outer wall of described interior pipe, thus the front end making described outer tube 3 is closed state, and the rear end 8 of described outer tube is what open wide; And protective casing 4; it is set in the outside of described outer tube 3; the front end of described protective casing is connected with the front end of described outer tube, and the rear end of described protective casing is connected with the outer wall of the rear end of described outer tube, to form an air cavity 10 closed in the outside of described outer tube.
During drain, the insertable part of interior pipe is inserted into wound, and because the aperture of side opening is less, liquid can not flow directly into in outer tube, or only has small part and flow in outer tube, and interior pipe still plays main drainage, and liquid is finally discharged from the rear end of interior pipe.When drainage tube is subject to external force extruding, liquid can be squeezed and enter to outer tube by side opening, and discharges from the rear end of outer tube.Based on above-mentioned design, even if drainage tube is squeezed, liquid also can not flow back to wound.
Meanwhile, protective casing 4 forms an air cavity closed around outer tube, has good cushioning effect, the squeezing action of internal pipe is reduced to extruding.
In described drainage tube, the tube wall of described protective casing 4 is outwardly formed with multiple air chamber 6, communicates with each other between described air chamber 6 and described air cavity 10.When drainage tube is squeezed, air chamber also can play cushioning effect.When squeezing action is excessive, the gas in air chamber enters in air cavity, and air chamber can not be crushed easily.
In order to make the easier Exhaust Gas of air chamber, air chamber wall is more yielding, and to reduce air chamber by the probability crushed, in described drainage tube, the locular wall of described air chamber 6 is less at the thickness of tube wall of the part not forming air chamber than described protective casing.
Particularly, in described drainage tube, the thickness of the locular wall of described air chamber is 0.1mm, and described protective casing is 0.3mm at the thickness of tube wall of the part not forming air chamber.
In described drainage tube, the tube wall lateral surface of described protective casing is evenly distributed with multiple air chamber, communicates with each other between air chamber.Air chamber provides ground floor to protect, and air cavity provides the second layer to protect, but is not communicated with between air chamber with air cavity, is only communicated with between air chamber, to reduce single air chamber by the probability crushed.
In order to provide enough protections, in described drainage tube, the thickness of described air chamber is 2 ~ 3mm.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the general concept that claim and equivalency range limit, this utility model is not limited to specific details and illustrates here and the legend described.
