Background

Intermittent catheterization is a daily routine that occurs several times a day for a large group of people. Typically, catheters for intermittent catheterization are used by individuals suffering from urinary incontinence or by disabled individuals (e.g., paraplegic or quadriplegic) who may have no control over permitting spontaneous urination and for whom catheterization may be a urinary modality. Using intermittent catheters, the bladder may be emptied through a natural or artificial urinary catheter. It is achieved that the catheter assembly, which is small and discrete for transportation and handling, significantly improves the quality of life of a large group of individuals, in addition to being easy to use even for individuals with reduced flexibility. At present, a common urine collecting bag is characterized in that a liquid guide tube extends into a bag body and is thermally combined with the bag body at a sealing position of the bag body. However, once the bag is squeezed, the liquid in the bag can flow back into the catheter, causing an inconvenient use. To this end we propose a disposable urine collection bag with backflow prevention and self-sealing to solve the above problems.
