Urine educing device with bent hollow guide head

Abstract

The invention provides a urine educing device with a bent hollow guide head. The head end of the urine educing device comprises an insert tube head and an insert tube guide head, wherein the insert tube head comprises a conical section, a transitional section and a joint section; the diameter of the transitional section is gradually increased from the diameter of the bottom end of the conical section to the diameter of the joint section; the diameter of the joint section is outer diameter of the middle section of an insert tube; the conical section is internally provided with a lubricant nozzle inner hole and an insert tube guide head mounting stepped hole; the side wall of the lubricant nozzle inner hole is provided with at least one radial lubricant nozzle; the insert tube guide head mounting stepped hole and the insert tube guide head at the front end of a hollow guide core are tightly, easily and detachably matched; the joint section is provided with an insert tube mounting stepped hole; at the head end, the hollow guide core comprises an insert tube guide head at the front end, an insert tube of the transitional section and an insert tube of a straight section; a lubricant enters into a urine duct by virtue of the lubricant nozzle inner hole and the lubricant nozzle. According to the urine educing device, the thrusts of the insert tubes can be concentrated at the head end of a urine guide tube; the lubricant is capable of lubricating and expanding the urine duct in the whole process, further reducing the resistance of the insert tubes and reducing the inner wall damage of the urine duct.

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 ...
