Embodiment Construction

[0018] Such as Figure 1-5 As shown, the urinary catheter dredging brush includes a winding microcatheter 1 and a guide wire 2, the outer diameter of the microcatheter 1 is matched with the inner hole of the urinary catheter, and the guide wire 2 is made of metal material. The diameter of the guide wire 2 is matched with the inner diameter of the microcatheter 1. The guide wire 2 is arranged in the microcatheter 1 in an axially movable manner. Composed of fiber filaments made of molecular materials, in order to facilitate more efficient removal of blockages in the tube and reduce irritation to the human body, the cilia end of the ciliated ball 3 is preferably barb-shaped, and the cilia end of the ciliated ball 3 It is preferably spherical.

[0019] In order to control the movement of the guide wire 2 more precisely, and then precisely control the position of the ciliary bulb 3 , as a further configuration of the present invention, a driving mechanism for the guide wire 2 is p...

Abstract

The invention relates to the field of medical instruments, in particular to a dredging brush of a urinary catheter. The dredging brush is used for dredging the indwelling urinary catheter. The dredging brush of the urinary catheter comprises a flexible micro-catheter and a guide wire. The external diameter of the micro-catheter and an inner hole of the urinary catheter are in clearance fit, the diameter of the guide wire and the inner hole diameter of the micro-catheter are in clearance fit, the guide wire is arranged in the micro-catheter in an axial moving mode, a cilium ball is arranged atthe front end of the guide wire, and a guide wire locking mechanism is arranged at the tail end of the micro-catheter. By means of the dredging brush, when foreign matter blocks the urinary catheter,the micro-catheter and the guide wire enter a catheter cavity together from an outer opening of the urinary catheter to be brushed, the foreign matter is removed, the urinary catheter is kept smooth,and the trauma and pain caused by re-inserting of the urinary catheter are avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a urinary catheter dredging brush for dredging an indwelling urinary catheter. Background technique [0002] In clinical medicine, in the case of bladder bleeding or other debris-like secretions that easily block the urinary catheter, it is necessary to indwell the patient with sterile saline to continuously flush the bladder so that foreign matter such as urine and blood in the bladder can pass through. Urinary passage of the urinary catheter out. However, in the process of bladder flushing, the above-mentioned foreign bodies often block the catheter inner cavity and the opening of the catheter tip, and the blood clot cannot be removed when the catheter is pressurized and flushed, and it is often necessary to replace the catheter and remove the original catheter Urinary catheterization, indwelling catheter again, aggravates the possibility of bleeding in the original surgical wou...
