Anti-blockage easily inserted three-cavity catheter device

Abstract

The invention discloses an anti-blockage easily inserted three-cavity catheter device, which comprises a catheter, and a blood clot breaker and an inner core, which are matched with the catheter; a spring steel wire is arranged in the wall of the catheter; a saccule is arranged on the front of a water cavity; an elliptical hole is formed on the middle ring surface of the saccule; due to the arrangement of the spring steel wire, the wall thickness of the catheter is reduced, an inner cavity of the catheter is enlarged, the blockage is reduced, and the smooth drainage is ensured; the spring steel wire has elasticity, the spring steel wire is squeezed and deformed a little when inserted, is expanded after being inserted, and is elastically fixed with a urethra so as to avoid a urine leakage phenomenon; the saccule is arranged on the front of the water cavity, and is provided with a drainage hole; and when the drainage is not smooth due to blood clots, the blood clot breaker is used for breaking the blood clots to ensure the smooth drainage.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a catheterization device. Background technique [0002] The existing catheters are made of polymer materials. Because the polymer materials are soft, in order to meet the requirements of use, the tube wall of the catheter is made thicker, resulting in a smaller inner cavity, so it is easy to produce Tube blockage, especially when there is a blood clot, makes it difficult to insert into the bladder, and urine leakage often occurs, or the insertion is extremely difficult, which makes the patient uncomfortable and uncomfortable. Mainly because the catheter itself lacks elastic fixation with the urethra. Contents of the invention [0003] The object of the present invention is to provide a three-chamber urinary catheterization device capable of breaking blood clots, having a wide drainage cavity, bending resistance, easy insertion, and urine leakage prevention.
