Description
Technical Field
The utility model relates to a drainage tube antiseep device belongs to medical equipment technical field.
Background
Percutaneous Transhepatic Cholecystal Drainage (PTCD) is a technical means for placing bile ducts in the biliary tract percutaneously and transhepatically under the guidance of an imaging technique, and for many biliary tract diseases, PTCD is a preferred treatment scheme and can also be a palliative treatment method.
Specifically, a puncture trocar is inserted into a biliary tract to establish a channel, so that a drainage tube is implanted to drain bile, and the drained bile is collected by a drainage bag.
The drainage bags used by current PTCDs mainly suffer from the following problems:
liquid seepage: at the initial stage of inserting the drainage tube into the abdominal cavity of a patient, as the muscle tissue, the fat tissue, the liver capsule and the drainage tube of the patient are tightly attached, the condition that bile seeps out along the outer side of the tube wall of the drainage tube can not occur, and the attaching force of the muscle fat and the wall of the drainage tube of the patient is reduced for old people and weak patients, so that the bile of the patient often seeps out along the outer side of the tube wall of the drainage tube, the discomfort and the panic of the patient can be caused, the skin nearby can be polluted, the skin itch. Meanwhile, the muscle adipose tissues are not tightly attached to the drainage tube wall, and skin colonizing bacteria and in-vitro pathogenic bacteria are likely to reversely migrate into the abdominal cavity to cause infection.
