Long-term biliary drainage device for beagles

Abstract

The invention discloses a long-term biliary drainage device for beagles. The long-term biliary drainage device comprises a percutaneous introducer, an anti-fall-off drainage catheter, a drainage pipefixing sticker, a disposable anti-reflux biliary drainage bag, a beagle interior protecting garment and a beagle exterior protecting garment and is characterized in that the percutaneous introducer comprises an introducing sheath, an inner sheath, a puncture needle and a guide wire, the inner sheath is arranged in introducing sheath, the puncture needle is inserted into the inner sheath, and the inner sheath, the introducing sheath and the puncture needle are sequentially serially connected to form the component of the introducer; the anti-fall-off drainage catheter comprises an anti-fall-offlock and a drainage pipe; the drainage pipe fixing sticker comprises a catheter fixing device and a skin fixing sticker, and the spiral connector end of the disposable anti-reflux biliary drainage bagis connected with the other end of the anti-fall-off lock; the beagle interior protecting garment is a rectangular interior protecting garment made of Lycra; the beagle exterior protecting garment comprises a protecting outer garment, a collar and fixing straps, the collar is arranged on the front side of the protecting outer garment, and the fixing straps are fixedly arranged on two adjacent sides of the front side of the protecting outer garment.

Description

technical field [0001] The invention relates to a drainage device, in particular to a long-term bile drainage device for Beagle dogs. Background technique [0002] Bile is a digestive juice secreted by the liver and bile ducts; Enterohepatic Circulation (ETC) refers to the substances excreted by the liver (including drugs, endogenous substances and poisons, etc.) Enter the whole body circulation process. Current studies have found that atorvastatin, colchicine, etc., as well as endogenous substances (such as bile acids, toxic substances such as lead, and organic chlorine compounds) in the drug all have enterohepatic circulation, and the existence of the drug ETC can cause the drug to appear bimodal. Or multi-peak phenomenon, which helps to improve the bioavailability of drugs and enhance drug efficacy; however, the accumulation of endogenous substances and toxic substances ETC in the human body for a long time will cause harm. Bile drainage can not only treat biliary obstr...

AI Technical Summary

Problems solved by technology

The silicone / latex T-shaped drainage tube is soft and will not cause damage to the common bile duct, but it is easy to fall off; and dogs are active and active, so the experiment can only monitor the bile excretion in dogs under anesthesia, and can only study short-term Bile excretion, while the anesthetized state of Beagle dogs will affect bile secretion and excretion, and anesthetics may also interfere with poison metabolism, resulting in biased experimental results, which is also contrary to animal ethics and the "3R" principle
