The invention belongs to the field of medical tools, and provides a split type leakproof
catheter which comprises an
insertion tube, one end of the
insertion tube is integrally and fixedly connected with a tip, the other end of the
insertion tube is integrally and fixedly connected with a connecting tube, the connecting tube is used for being communicated with an input tube of a
urine collection bag, and
branch tubes fixedly penetrate through the side wall of the connecting tube in a
central symmetry mode; a valve is installed on the
branch pipe,
urine inlet holes are formed in the position, close to the pointed end, of the insertion
pipe in a
central symmetry mode, an anti-disengaging piece used for preventing the insertion
pipe from disengaging is arranged at the position, close to the
urine inlet holes, of the insertion pipe, and the anti-disengaging piece comprises a water injection
balloon fixedly connected to the insertion pipe. By means of the technical scheme, moderate pressure can be applied to the urethral wall through controllable inflation, closing performance is enhanced,
urine leakage beside the insertion tube is reduced, the technology is particularly suitable for elderly women and neurogenic bladder or
sphincter insufficiency patients, the
urine leakage amount can be effectively reduced, and the occurrence rate of incontinence dermatitis caused by the fact that the
skin of the patients is affected by urine is reduced.
