Description

Drainage tube assembly with inner sleeve flushing function Technical Field The utility model relates to the technical field of medical instruments, in particular to a drainage tube assembly with an inner sleeve for flushing. Background In drainage therapy after clinical surgery, drainage tubes are often left at the patient's focus to drain out fluid, pus and necrotic tissue in the body. However, since the drainage fluid often contains viscous proteins, tissue fragments or coagulum, the drainage tube is extremely prone to lumen blockage during continuous drainage, leading to drainage failure and even serious abdominal infection. When the drainage tube is blocked, medical staff needs to manually flush and dredge the drainage tube, the external liquid inlet tube and the negative pressure tube are used as the inner sleeve tube to be inserted into the cavity of the drainage tube, the inner sleeve tube is pushed to the deep part where the blocking occurs or the working position in the patient body which really needs to be cleaned, the soft catheters are easy to bend, curl and even knot when encountering resistance, are difficult to smoothly go deep and reach the target working position in the patient body which really needs to be flushed or pumped, the dredging failure is caused, the consumed time is long, the risk of pipeline pollution is possibly increased, and the rehabilitation process of the patient is influenced. Disclosure of utility model Aiming at the defects in the prior art, the utility model aims to provide a drainage tube assembly with an inner sleeve tube for flushing, which can be used for rapidly guiding flushing. In order to solve the technical problems, the drainage tube assembly with the inner sleeve flushing function comprises an outer sleeve and an inner sleeve, wherein the distal end head of the outer sleeve is inwards curved to close, a plurality of side holes for draining seepage are formed in the distal end tube wall of the outer sleeve, a drainage bag connector is arranged at the proximal end of the outer sleeve, and a manifold communicated with a tube cavity of the drainage tube is arranged at the proximal end of the outer sleeve, wherein: the remote end lumen internal fixation of outer tube has the steering strip, the manifold mouth of pipe is equipped with the cross silica gel valve, the stay cord has been wound on the steering strip, the both ends of stay cord pass the cross silica gel valve and extend to the manifold outside, and the one end of stay cord is fixed with the pull ring, and the other end and the interior sleeve pipe rigid coupling of stay cord, interior sleeve pipe has two lumen, is feed liquor chamber and drawing liquid chamber respectively. Further, a plurality of liquid inlet holes are formed in the distal end of the liquid inlet cavity. Further, a pull rope caulking groove is formed in the steering strip. According to the drainage tube assembly with the inner sleeve for flushing, the inner sleeve is pulled by the stay cord, so that the inner sleeve can be pulled to the far end of the outer sleeve rapidly, the dredging process of the drainage tube is quickened, and the pollution of a pipeline can be effectively avoided.
