Abstract
The utility model discloses a medical drainage tube comprising an inner tube, wherein the wall of the inner tube is provided with a plurality of through holes, a protective tube is arranged outside the inner tube, a gap with a certain width is arranged between the protective tube and the inner tube, and the wall of the protective tube is provided with at least one clearance communicated with the gap. The medical drainage tube is additionally provided with the protective tube, and the protective tube is internally provided with the clearance, so that muscles are prevented from being embedded into the through holes of the inner tube during a drainage operation, furthermore, the pain of a patient can be relieved, the secondary injury for the patient can be avoided, and meanwhile, the drainage smoothness can be improved.
Description
Technical field
This utility model relates to armarium, is specifically related to a kind of medical drainage tube.
Background technology
Medical drainage tube is generally used for surgical operation, by drainage tube by between tissue or the pus gathered in body cavity, blood and liquid etc. be directed to external, thereby prevent postoperative infection and affect wound healing.At present, the body that the drainage tube used in hospital is single layer structure, and be provided with a plurality of through holes in body.In operation process, utilize these drainage tubes to insert in human body and carry out drain.When surgical drainage, due to pressure-acting, the muscle of human body embeds in the through hole of body, therefore when pulling out in human body, need to provide larger withdrawal force when drainage tube, through hole can produce the effect that pull to muscle simultaneously, thereby increase patient's misery, even cause secondary insult.
The utility model content
The deficiency that this utility model exists in order to overcome above prior art, provide a kind of simple and reasonable for structure, can avoid causing the medical drainage tube of secondary insult.
The purpose of this utility model realizes by following technical scheme: this medical drainage tube; comprise inner tube; the tube wall of described inner tube is provided with a plurality of through holes; described inner tube is provided with protecting tube outward; be provided with the gap of one fixed width between described protecting tube and inner tube, the tube wall of described protecting tube is provided with at least 1 gap communicated with gap.
As a kind of preferred, the quantity in described gap is 2, and the centrage symmetry of 2 relative protecting tubes in gap.This distribution of forces that can allow protecting tube be subject to is even, and the deformation of avoiding protecting tube to occur because of pressure affects the effect of drain.
As a kind of preferably, described gap is linearly, and parallel with inner tube.Particularly, linearly, insert this medical drainage tube or while extracting human body, gap can not magnified in gap, thereby to can not scratch muscle.
The length in described gap is 15mm～25mm.The length in described gap determines according to the through hole dispersion of distribution of inner tube.
As a kind of preferred, the quantity in described gap is 1, and described gap in the shape of a spiral.When gap, in the shape of a spiral the time, medical personnel adopt the mode of rotation insert human body or extract in human body, and this is avoided scratch muscle, reduce pain.
Described protecting tube is cylindrical.The cross sectional shape of described protecting tube can also be triangle or rectangle, and the cross sectional shape of protecting tube of the present utility model is annulus, and protecting tube is cylindrical.
Described medical drainage tube also comprises at least 1 connector, and the inwall of described protecting tube is fixedly connected with the outer wall of inner tube by connector.
For improving the stability of protecting tube, the quantity of described connector is 2, and described 2 relative inner tubes of connector are symmetrical arranged.
As planting preferably, the width size in described gap is 1mm～3mm.
The ratio of the thickness of the thickness of described protecting tube, the width in gap and inner tube is 1:2:1.
The work process of this medical drainage tube: medical drainage tube is inserted to human body, and the liquid in human body enters inner tube through gap and through hole successively, and liquid is directed to human external by inner tube, thereby completes the process of drain.
This utility model has advantages of as follows with respect to prior art: this medical drainage tube is by setting up protecting tube, and be provided with gap in protecting tube, when carrying out surgical drainage, thereby avoid muscle to embed in the through hole of inner tube, therefore can reduce patient's misery, avoid patient is caused to secondary insult; The protecting tube that this medical drainage tube is set up is cylindrical, and both convenient processing, also avoided stress concentration simultaneously, thereby reduces patient's pain; This medical drainage tube is by setting up protecting tube, thereby the human muscle embeds flowing of the liquid that affects inner tube in the through hole of inner tube, thereby improved the smoothness of drain.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of medical drainage tube of embodiment 1.
Fig. 2 is the left view of a kind of medical drainage tube of embodiment 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1
A kind of medical drainage tube as depicted in figs. 1 and 2; comprise inner tube 1; the tube wall of described inner tube 1 is provided with a plurality of through holes 2; the outer protecting tube 3 that is provided with of described inner tube 1; be provided with the gap 5 of one fixed width between described protecting tube 3 and inner tube 1; the tube wall of described protecting tube 3 is provided with 2 gaps 4 that communicate with gap 5, and the centrage symmetry of 2 gap 4 relative protecting tubes 1.Symmetrically arranged gap 4, this distribution of forces that allows protecting tube 3 be subject to is even, and the deformation of avoiding protecting tube 3 to occur because of pressure affects the effect of drain.
As a kind of preferably, described gap 4 is linearly, and parallel with inner tube 1.Particularly, linearly, insert this medical drainage tube or while extracting human body, gap 4 can not magnified in gap 4, thereby to can not scratch muscle.
The length in described gap 4 is 20mm.The length in described gap 4 determines according to through hole 2 dispersions of distribution of inner tube 1.
Described protecting tube 3 is cylindrical.The cross sectional shape of described protecting tube 3 can also be triangle or rectangle, and the cross sectional shape of protecting tube 3 of the present utility model is annulus, and protecting tube 2 is cylindrical.
