Abstract

The invention discloses a novel intestinal obstruction catheter with rushing and suction functions. The novel intestinal obstruction catheter comprises an inner sleeve and an outer sleeve sleeving theend of the inner sleeve, a first rushing hole is formed in the end of the outer sleeve, a second rushing hole is formed in the end of the inner sleeve, and a plug sidably sleeves the outer wall of the inner sleeve. A pipe opening of the inner sleeve is connected with a water supply device, a lateral opening is formed in the wall of the outer sleeve, and the lateral opening is connected with a negative-pressure suction device. The outer sleeve is provided with a supporting assembly used for supporting the outer sleeve against the inner wall of the anorectum, the supporting assembly comprises asupporting air bag, a bag guide pipe and an air-charging device, a containing groove is formed in the outer wall of the outer sleeve, the supporting air bag is limited into the containing groove, a guide groove is formed in the outer wall of the outer sleeve, the bag guide pipe is located in the guide groove, and the two ends of the bag guide pipe are connected to the supporting air bag and the air-charging device respectively. The volume of the supporting air bag for supporting the outer sleeve against the inner wall of the anorectum is easy to adjust.

Description

technical field

[0001] The invention relates to the field of medical equipment, and more specifically relates to a novel intestinal obstruction catheter with flushing and suction. Background technique

[0002] Intestinal content obstruction caused by any reason is collectively referred to as intestinal obstruction. It is one of the common surgical emergencies. Sometimes acute intestinal obstruction is difficult to diagnose, and the disease develops rapidly, often causing death of the patient.

[0003] For intestinal obstruction, the use of anal intestinal obstruction catheter is a very effective treatment method, which can avoid the complications that occur after one-stage resection and anastomosis without intestinal preparation before operation, and can avoid the need for urgent surgery. Disadvantages of secondary operation after colostomy.

[0004] In the prior art, the ileus catheter is supported on the inner wall of the anorectum through expansion of the water bladder...
