Bile reinfusion type double-cavity T-shaped tube

Abstract

The invention discloses a double-cavity T-shaped tube capable of recycling bile. The double-cavity T-shaped tube is characterized in that a vertical section of a double-cavity T-shaped tube main bodyis a T tube, and a parallel section of the double-cavity T-shaped tube main body is a T arm; the T tube is internally provided with a large tube cavity and a small tube cavity, and the larger tube cavity and a large tube cavity in the T arm mutually communicate and are both used for draining the bile; a free long separate pipeline penetrating out from an outlet in one side of the T arm section isformed on the T arm section by the small tube cavity and communicates with the small tube cavity in the T tube wall, and the free long separate pipeline and the small tube cavity are both bile reinfusion passages; a guide wire is assembled in the small tube cavity, and the small tube cavity can be sent into the duodenum through the guide wire; a one-way valve is arranged on the small tube cavity wall in the middle and lower section of the T tube and is open facing the small tube cavity, and when an outlet of the large tube cavity is clamped, the bile flows into the small tube cavity from the one-way valve, and enters the duodenum for bile reinfusion; and the other end of the T tube is connected with two outlets for bile drainage and reinfusion, and reinfusion pipeline flushing correspondingly. Smooth bile drainage after surgery can be guaranteed, the bile can also be effectively reinfused into an intestine, and thus the purpose of accelerating rehabilitation is achieved.

Description

Technical field [0001] The invention relates to a double-cavity T-shaped tube capable of reinfusing bile that needs to be used in the biliary tract exploration operation for patients in the medical field, and is a disposable medical product. Background technique [0002] Bile duct stones, biliary inflammation, and biliary obstruction caused by various reasons require biliary exploration and T-tube drainage. At present, the T-tubes used in major hospitals in China are made of latex. They are composed of two "arms" and a long drainage tube. (In the operation, the arm of the T-tube is placed in the patient's common bile duct, the T-tube drainage tube passes through the abdominal wall under the patient's right costal margin to the outside, and is sutured and fixed on the skin. Bile flows into the intestinal tract through one part of the T-arm and the other part into the T-tube. Tube to the drainage bag. The purpose of placing the T tube: 1 to drain bile, reduce the pressure of ...

AI Technical Summary

Problems solved by technology

Recycle and store the bile before reinfusion. Recycling and storage will cause secondary pollution and damage to the components of the bile. If the storage time is too long, the bile may deteriorate.

Oral bile will cause damage to the gastric mucosa of the patient. The bile is extremely bitter, difficult to swallow and has an unpleasant taste. Oral bile will cause great psychological disturbance to the patient, and the bile acts on the small intestine and enters the stomach after oral administration. affect the efficacy of bile

The reinfusion of bile combined with enteral nutrition via nasoenteric tube or jejunostomy may cause mechanical irritation and comfort to the gastrointestinal mucosa and the skin around the stoma because the catheter remains in the body for a long time. In particular, the insertion of enterostomy tube requires surgical operation, which increases the patient's pain, risk of infection and economic burden
