Blockage-preventing fixable uterine cavity irrigation and drainage tube

Abstract

The invention discloses a blockage-preventing fixable uterine cavity irrigation and drainage tube, which comprises a drainage tube, a clamp, a locking sleeve, an air bag, a trachea, a trachea seat, aself-locking stainless steel tie, an outer tube, a ball head and a spacer. The outer tube contains the clamp, the locking sleeve, the air bag, the trachea, the trachea seat and the self-locking stainless steel binding tape in the lumen; the spacer disk is fixedly arranged in the ball head; the ball head is fixedly arranged under the outer tube and six drainage holes are arranged; and two elliptical restraint holes are arranged near the lower end of the outer tube; the balloon can be bulged from the restraining hole, and the drainage tube is a double lumen, which is respectively introduced intoan irrigating fluid and a tumor tissue or necrotic tissue which is hematocele, pus, exfoliation and hematocele. Compared with the prior art, the blockage-preventing fixable uterine cavity irrigationand drainage tube accords with the anatomical characteristics of the inverted triangle of the uterine cavity, is not easy to protrude, is not easy to cause pain when expanding, is easily clogged, canrealize thorough irrigation and unobstructed drainage, and can avoid air and drainage fluid backflowing resulting in uterine cavity pollution.

Description

technical field [0001] The invention relates to a medical device, in particular to an anti-clogging and fixable uterine cavity flushing and drainage tube. Background technique [0002] For patients with advanced cervical cancer and uterine body cancer who are not suitable for surgery due to obesity, coronary heart disease, and diabetes, transvaginal intracavitary retroloading therapy is an indispensable and main treatment method. Cervical tumors and uterine cavity tumors are accompanied by inflammatory reactions during the tumor growth process; the process of exploring the uterine cavity and placing the uterine cavity treatment tube after loading treatment is an invasive operation, which is easy to bring external bacteria into the uterine cavity and induce infection; Uterine corpus tumors continue to necrosis as the treatment progresses, and the inflammatory response is aggravated, eventually causing intrauterine infection. The number of infertility and intrauterine adhesio...

Problems solved by technology

The disadvantages of placing a double-lumen or triple-lumen drainage tube are: the fixation is not good, and it is easy to prolapse when the abdominal pressure increases such as coughing; in addition, the catheter is easily blocked by detached tumor tissue or necrotic tissue, and the drainage tube can cause pus reflux after the drainage tube is blocked; The bottom is narrow and the top is wide. If the water bladder is located in the narrow cervical isthmus during fixation, it may cause severe pain
