Problems solved by technology
In the prior art, the air bag cover is mainly stretched manually, and then loosened after being inserted into the drainage tube so that the two are socketed. During the relaxation process, the position of the air bag cover relative to the drainage tube will shift, resulting in a large assembly error with the drainage tube , easily lead to defective products

The invention discloses a balloon sleeve spreading and fixing device for urinary catheter. The balloon sleeve spreading and fixing device for urinary catheter comprises a base, a spreading mechanism,and a fixing mechanism. The spreading mechanism is movably installed on the base and includes a first driving unit and a spreading unit. The spreading unit includes at least three spreading arms. Thefirst driving unit can drive at least three spreading arms to spread the balloon sleeve out. The fixing mechanism is movably installed on the base and includes a second driving unit and a fixing unit.The fixing unit includes at least three fixing arms. The fixing arms are parallel to the spreading arms and are disposed face to face. The second driving unit can drive at least three fixing arms toclamp and fix the spread the balloon sleeve on the drainage catheter. With the technical solution, when the spreading arm releases the balloon sleeve, the balloon sleeve is still clamped and fixed bythe fixing arm, so that the balloon sleeve is not easily pulled by the spreading arm, thereby reducing position error of the balloon sleeve after being connected to the drainage catheter.
Description
technical field [0001] The invention relates to the technical field of cannula machines, in particular to a stretching and fixing device for a balloon sleeve of a urinary catheter. Background technique [0002] The urinary catheter is mainly used to excrete the urine in the body, which is very helpful to people with physical inconvenience and incontinence, and is widely used in medicine at present. A urinary catheter is a tube made of rubber, silicone or plastic that is inserted through the urethra into the bladder to drain urine. The urinary catheter mainly includes a balloon sleeve and a drainage tube. When the catheter is inserted into the bladder, the balloon sleeve near the head end of the catheter is inflated to inflate the bladder sleeve so that the catheter is stuck in the bladder and is not easy to come out. In the prior art, the air bag cover is mainly stretched manually, and then loosened after being inserted into the drainage tube so that the two are socketed. D...
