Abstract

The present invention provides an external drainage catheter for surgery, which comprises a drainage end, a fixed balloon and a catheter body, wherein the drainage end, the fixed balloon and the catheter body are flexibly connected in a linear manner , the drainage end has at least two drainage grooves, each of the drainage grooves is opened backward from the drainage end and extends a predetermined distance, the fixed airbag has an inner wall and an outer wall, and an inner channel and a cavity, the The annular cavity is formed between the inner wall and the outer wall, the inner wall forms the inner channel, the drainage groove communicates with the inner channel, the main body of the catheter has a main channel, and the drainage end is provided with a main channel. The drainage groove, the inner channel of the fixed airbag, and the inner channel of the urinary catheter main body are sequentially connected to form a drainage channel, and the urinary catheter main body has an inflation channel, and the inflation channel communicates with the cavity. .

Description

technical field [0001] The invention relates to the field of medical supplies, and furthermore, relates to an external drainage catheter applied after surgery. Background technique [0002] A urinary catheter is a medical device used to drain urine from the bladder through the urethra. In terms of use, there are roughly two types of urinary catheters. One is ordinary urinary catheters, that is, catheterization medical supplies that are temporarily used when the user has difficulty urinating. The way of inserting a common urinary catheter assists urination; the other is an indwelling urinary catheter, which is mainly used to carry a fixed drainage for a long time, such as within 7 days. [0003] Regardless of whether it is an ordinary urinary catheter or an indwelling urinary catheter, due to the inevitable occurrence of a small amount of bleeding in the patient's body during or after some operations, the circulatory function of the human body will be weakened to a certain e...
