Description
Technical Field
The utility model relates to the technical field of drainage tubes, in particular to a replaceable drainage tube.
Background
In hospitals, a part of patients may need to place the drainage tube for a long time after a major operation, and the drainage tube may become an infection source after the placement time is long, or the drainage tube is blocked by foreign matters to lose the drainage effect; if the drainage tube is directly pulled out, the subsequent placement of the drainage tube with the same width along the original channel is easy to fail, the channel can be lost, and the patient can be hurt and painful due to the reluctant insertion; a replaceable drain is therefore designed for this situation.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides a replaceable drainage tube.
In order to solve the technical problems, the technical scheme provided by the utility model is that the replaceable drainage tube comprises: comprises a drainage tube and an outer sheath, wherein the drainage tube is matched with the outer sheath;
the drainage tube comprises an inner tube, an outer tube, a connecting tube and a connector, wherein the inner tube is arranged in the outer tube, two ends of the inner tube are connected with two ends of the outer tube, a cavity is formed between the inner tube and the outer tube, the connecting tube is arranged at one end of the outer tube, one end of the connecting tube, which is connected with the outer tube, is communicated with the cavity, and the other end of the connecting tube is provided with the connector;
the inner pipe is provided with a pipe body, one end of the pipe body extends out of the outer pipe, and the outer pipe and the outer sheath are both provided with length scales;
the outer tube is made of an elastic material.
As a refinement, the outer sheath inner diameter is slightly larger than the outer tube diameter.
Compared with the prior art, the utility model has the advantages that: the proposal comprises a drainage tube and an outer sheath, and the outer tube of the drainage tube is made of elastic material, so that when the drainage tube needs to be replaced, air or water in the cavity can be discharged through the connecting tube and the connecting head, at the moment, the outer tube of the drainage tube is contracted, the diameter of the drainage tube is reduced, then the outer sheath can be sleeved on the drainage tube from one end of the drainage tube and placed along the drainage tube, then the old drainage tube is taken out, then a new drainage tube is placed along the outer sheath, then the outer sheath is taken out, air or water is injected into the cavity through the connecting pipe and the connecting head, so that the outer tube is expanded to reach the original diameter, namely the replacement is finished, length scales are arranged on the outer tube and the outer sheath, the insertion depth of the drainage tube can be conveniently known, the drainage tube and the outer sheath can reach the same depth, the structure is simple, the use is convenient, the replacement is convenient, and the pain of a patient can not be caused.
