Abstract

The utility model relates to the technical field of drainage tubes, and discloses a sandwich drainage tube which comprises an outer tube and an inner tube, wherein one end of the inner tube is positioned at the inner side of the outer tube, the other end of the inner tube penetrates through the side wall of the other end of the outer tube and is fixedly connected with the outer tube, a plurality of lavage channels are communicated between one end of the inner tube positioned in the outer tube and the outer tube, a plurality of export holes and a plurality of import holes are formed in the outer wall of the outer tube, which is close to one end of the lavage channels, the import holes are respectively communicated with the lavage channels, and the export holes are respectively positioned between two adjacent lavage channels. This kind of sandwich drainage tube, through lavage passageway, keep apart the inner chamber of inner tube and the inner chamber of outer tube for the liquid that lavage was in to the patient's body through the inner tube directly gets into the patient through the introduction hole, thereby avoid lavage liquid to be directly derived by the outer tube, improve lavage efficiency, alleviate patient lavage treatment burden.

Description

Sandwich drainage tube Technical Field The utility model relates to the technical field of drainage tubes, in particular to a sandwich drainage tube. Background The sandwich drainage tube has a double-tube structure, also called a double-sleeve drainage tube, and is usually composed of two hoses with different diameters, the inner cavity of the outer tube and the inner tube can be used for flowing liquid, and can be used for guiding excessive liquid (such as blood, pus, bile, lymph and the like) in a body to be led out of the body in medical treatment, so that infection and other complications are prevented. The utility model discloses a double-set washing drainage tube as in the patent of publication number CN221579392U, including the rubber drainage tube, equal fixedly connected with fixed block around the inside right side of rubber drainage tube, the one end fixedly connected with washing inner tube that the rubber drainage tube was kept away from to the fixed block, wash inner tube left side fixedly connected with magnet ring, all fixedly connected with installation piece around washing inner tube left side upper portion, installation piece inside rotation is connected with the connecting axle, connecting axle outside fixedly connected with shelters from the subassembly, wash inner tube upper portion fixedly connected with subassembly that intakes. Through the cooperation between rubber drainage tube, fixed block, washing inner tube, magnet ring, installation piece and the connecting axle isotructure, realized that two sets of washing drainage tubes can wash rubber drainage tube when cleaning patient's abdominal cavity, prevent to tie absorption blocking drainage tube such as membrane, omentum, floc. However, the drainage tube in the above technique still has the following problems: During the in-service use period of the sandwich drainage tube, when lavage is carried out to the patient through the inner tube, lavage liquid flows out from the small holes at the tail end of the inner tube and flows into the outer tube easily, and when redundant liquid is led out through the outer tube, the lavage liquid is led out together, so that the lavage liquid cannot enter the patient completely to carry out lavage operation, the lavage effect is reduced, and then the lavage for a longer time is required to play a role in expectancy, so that more treatment burden is brought to the patient. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a sandwich drainage tube, for example, an inner tube cavity and an outer tube cavity are isolated, so that the lavage liquid is prevented from being led out without entering a patient, the lavage effect is improved, and the treatment burden of the patient is reduced. In order to achieve the purpose, the sandwich drainage tube comprises an outer tube and an inner tube, one end of the inner tube is positioned at the inner side of the outer tube, the other end of the inner tube penetrates through the side wall of the other end of the outer tube and is fixedly connected with the outer tube, a plurality of lavage channels are communicated between one end of the inner tube positioned in the outer tube and the outer tube, a plurality of guiding-out holes and a plurality of guiding-in holes are formed in the outer wall of the outer tube, which is close to one end of the lavage channels, in a penetrating mode, the guiding-in holes are respectively communicated with the lavage channels, and the guiding-out holes are respectively positioned between two adjacent lavage channels. Further, the plurality of lavage channels are evenly distributed on the outer wall of the inner tube at one end in the outer tube. Further, one end of the lavage channel is fixedly connected and communicated with the inner tube, and the other end is fixedly connected with the outer tube and communicated with a plurality of adjacent guide holes. Further, the number of the plurality of lavage channels is not less than three. Further, the diameter of the lead-out hole is not less than 2mm. Further, the diameter of the introduction hole is not more than 0.5mm. Further, the lavage channel, the inner tube and the outer tube are all made of soft materials. Compared with the prior art, the utility model has the following beneficial effects: This kind of sandwich drainage tube, through lavage passageway, keep apart the inner chamber of inner tube and the inner chamber of outer tube for the liquid that lavage was in to the patient's body through the inner tube directly gets into the patient through the introduction hole, thereby avoid lavage liquid to be directly derived by the outer tube, improve lavage efficiency, alleviate patient lavage treatment burden.
