Description

Anti-blocking catheter

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an anti-blocking catheter.

Background

It is well known to use urine drainage systems, such as urinary catheters, in various hospital and medical environments to drain urine from the bladder. Urinary drainage systems provide a pathway for urine to flow from a patient into a urine receptacle (e.g., a urine collection bag). Such urine drainage systems typically use indwelling catheters that are connected to a urine container (e.g., a "leg bag"). Thus, the system provides a flow path for urine from the patient's bladder to the urine receptacle.

In-dwellings (Foley) catheters are commonly used as a routine practice in many surgical procedures and are used by patients suffering from urinary incontinence or disabled persons (such as paraplegic or quadriplegic patients) who may not be able to control urination. Catheterization may be the only method of urination management. The urinary catheter is present in combination with a bag for collecting urine, which can be emptied into a toilet. Alternatively, they may be used with a manually operated valve to empty the bladder of urine directly into the toilet.
