Description

Technical Field

[0001] The utility model relates to a drainage tube fixing device. Background Art

[0002] Some patients will have a drainage tube inserted into their body after surgery to drain the accumulated fluid in the body, and the accumulated fluid enters the drainage bag for collection and cleaning. In order to facilitate the placement and handling of the drainage bag, the drainage tube usually reserves a longer length, which may cause the drainage tube to be entangled or delayed. Therefore, some auxiliary devices are needed to fix the drainage tube. For example, in the Chinese utility model with the authorization announcement number CN208274815U and the name "a drainage tube fixing device that can be installed and adjusted after surgery", a drainage tube fixing device that can be installed and adjusted after surgery is disclosed, including: an elastic clasp, the elastic clasp is used to be sleeved on any position where the drainage tube is inserted; and a fixing device shell, the fixing device shell has the function of opening and locking, and the fixing device shell has a hole in the center of the inner side for the drainage tube to pass through, and the hole has a groove that matches the shape of the elastic clasp, and the fixing device shell has holes at both ends for inserting a rope or a paper clip for easy fixation. In this patent, the drainage tube is fixed by an elastic clamp, which is troublesome to operate. In addition, a rope or a paper clip is inserted through the hole, which is also troublesome to operate. Overall, there are many accessories, which are easy to lose and are troublesome to use.

[0003] In the Chinese utility model patent with authorization announcement number CN215083963U and the name "A drawstring clip-type drainage tube fixing device", a drawstring clip-type drainage tube fixing device is disclosed, including a drawstring and a fixing part for fixing the drainage tube, the fixing part is arranged on the drawstring; the fixing part includes an upper fixing block and a lower fixing block, and the upper fixing block and the lower fixing block can be buckled.
