Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an anal canal fixing collector. Background Art

[0002] The anal tube is a commonly used device to relieve intestinal obstruction and promote gas and defecation. The depth of the intubation needs to be determined according to the depth of the lesion. The location of the intestinal lesion is usually determined by colonoscopy. The anal tube is generally made of a colloid hose, which causes less damage to the intestinal wall. When inserting the tube, try to pass through the lesion site or the obstruction site. Before intubation, try to use paraffin oil and other lubrication. If necessary, you can leave the tube to connect the drainage bag, observe the gas and defecation, check the cause of the obstruction as detailed as possible, and provide timely symptomatic treatment to prevent delays in the disease. In addition, during the treatment of patients with fecal incontinence, an anal tube is often used to assist defecation, which is conducive to keeping the environment clean and hygienic, reducing the contamination of beds by feces, and reducing the frequency of changing bedding and clothing.

[0003] The anal cannula is usually provided with an airbag structure to prevent slipping. When the cannula is inserted, the airbag enters the intestine with the cannula and is then inflated so that the airbag presses against the inner wall of the intestine after expansion, thereby achieving the anti-slip effect of the cannula through the friction between the airbag and the inner wall of the intestine.

[0004] In the related art, generally, when inserting the anal tube, the cannula can be extended into the colon, and the airbag can be pressed against the corresponding part of the rectum, so that the stool and gas in the colon can be conveniently drained out through the upper end of the cannula; however, if a lesion occurs in the rectum, the cannula is extended into the colon and the airbag is extended into the rectum, then the inflated airbag is likely to squeeze the lesion on the inner wall of the rectum, causing the patient to feel pain; since the airbag is fixed on the cannula, it is not easy to adjust, especially when the lesion of the rectum is close to the colon, then the airbag can only be moved down to below the lesion of the rectum, and the cannula will also move down at the same time, but at this time the stool at the upper end of the cannula becomes drier, making it inconvenient to insert the cannula for drainage and defecation. Utility Model Content

[0005] The utility model aims to provide an anal canal fixing collector to solve the problem that the position of the air bag on the cannula is inconvenient to adjust.

[0006] The utility model is realized by the following technical solutions:

[0007] An anal canal fixed collector comprises an insertion tube and an air bag, wherein the air bag is connected to an inflation tube, the outer wall of the insertion tube is provided with a plurality of plug-in holes along the length direction of the insertion tube, the outer wall of the insertion tube is sleeved with a tube sleeve, both ends of the tube sleeve are provided with soft plastic sheets, plug-in columns are provided on the soft plastic sheets, the plug-in columns are located in the plug-in holes and clamped with the inner walls of the plug-in holes, and the air bag is sleeved on the outside of the tube sleeve; the outer wall of the insertion tube is provided with a tube groove for embedding and installing the inflation tube along the length direction of the insertion tube, and one end of the inflation tube close to the air bag is located on the inner side of the tube sleeve and is connected with the air bag after passing through the inner wall of the tube sleeve.

[0008] Furthermore, multiple soft rubber sheets are circumferentially arranged at both ends of the sleeve, plug-in posts are arranged on the multiple soft rubber sheets, multiple plug-in holes are circumferentially opened on the outer wall of the insert, and the multiple plug-in posts are plugged in and matched with the plug-in holes one by one.

[0009] Furthermore, an infusion cavity is provided on the tube wall of the cannula along the length direction of the cannula, one end of the infusion cavity extends to the end of the cannula and is open, an infusion tube is provided on the cannula, and one end of the infusion tube close to the cannula is connected to the infusion cavity.

[0010] Furthermore, one end of the cannula away from the opening end of the infusion cavity is connected to a drainage bag, and the drainage bag is connected to the cannula by a thread.

[0011] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0012] In the utility model, when a patient with incontinence has a lesion in the rectum, a colonoscopy can be used to examine the patient and determine the specific lesion site of the rectum. Then, the soft plastic sheet can be pulled apart to separate the plug-in posts at both ends of the tube sleeve from the plug-in holes. At this time, the tube sleeve can be slid to adjust the position of the airbag on the cannula. After that, the plug-in posts on the soft plastic sheet are plugged into the corresponding plug-in holes to fix the airbag. When the cannula is inserted into the colon, the airbag can be pressed against the inner wall of the rectum where no lesions occur, so as to prevent the airbag from squeezing the lesion site of the rectum. According to the specific situation of the lesion site of the rectum, the airbag can be adjusted upward or downward. BRIEF DESCRIPTION OF THE DRAWINGS
