Urine drainage device capable of supplementing lubricant in real time

Abstract

The invention relates to a urine drainage device capable of supplementing lubricant in real time. The urine drainage device capable of supplementing lubricant in real time comprises a head end, a middle section, a tail end and a lubricant injection device, wherein the middle section comprises a urine guide cannula and a hollow guide core which is built in the urine guide cannula; a built-in cannula guide head which is formed by the front end of the hollow guide core is arranged at the head of the cannula at the head end; the tail end comprises a cannula tail locking device and a hollow guide core tail locking device; the cannula guide head of the head end and the hollow guide core of the middle section are integrated into a whole body; a lubricant spray nozzle of the hollow guide core is arranged at the downstream of the head of the cannula and the upstream of the cannula guide head, or is arranged at the foremost end of the head end; at the tail end, the cannula tail locking device is detachably jointed with the tail of the middle section of the cannula; the hollow guide core tail locking device is firmly bonded with the tail of the hollow guide core; the tail of the hollow guide core is communicated with the lubricant injection device through the hollow guide core tail locking device. The urine drainage device capable of supplementing lubricant in real time has the advantages that the cannula resistance can be reduced and the damage to the inner wall of a urethra is reduced; the urine drainage device can easily pass through narrow and obstructed parts in the body of a patient; the moving direction and the moving angle of a catheter can be accurately controlled.

Description

technical field [0001] The invention relates to a urinary catheter, in particular to a urine exporter capable of replenishing lubricant in real time. [0002] The urine exporter of the present invention comprises a well-known urinary catheter. Background technique [0003] Urinary catheterization is one of the main diagnostic and therapeutic procedures in urology. Before intubation, the catheter is usually coated with lubricant to reduce resistance, but during the operation stroke of more than 20 cm, the narrowest part is mostly located at the exit of benign prostatic hyperplasia. This part is at the end of the stroke. When the catheter reaches the site, the amount of lubricant remaining is too small, and the resistance of the catheter is high. Difficulty passing through the obstruction. [0004] Commonly used silicone rubber catheters are not hard enough. When the intubation tube is blocked, it is easy to bend and deform and difficult to insert. The thrust is difficult ...
