Closed bile reinfusion device

Abstract

The invention discloses a closed bile reinfusion device and belongs to the technical field of medical apparatus and instruments. The closed bile reinfusion device comprises a bile collection bag and a bile reinfusion device, wherein an input tube and an output tube are arranged on the bile collection bag; and the bile reinfusion device comprises a box body, a first storage slot, a conveying channel, a filter, an electronic scale, a sterilizer, a heater, a cooler, a peristaltic pump, a motor and a controller. The filter can be utilized for filtering crystals, bile sands, fiber secretions and the like existing in drained bile, the electronic scale can be utilized for detecting stock in the bile collection bag; the sterilizer, the heater and the cooler can be utilized for respectively sterilizing bile flowing through the output tube in a bile reinfusion process; and the peristaltic pump and the controller can be utilized for automatically completing control on stock quantity of the bile and automatic reinfusion, so that in vitro bile reinfusion can be timely and effectively realized. Compared with the prior art, the closed bile reinfusion device has the advantages of high refluxing efficiency, high accuracy and strong practicability.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a closed bile reinfusion device. Background technique [0002] In the 1980s, with the continuous deepening of the biological behavior of severe acute pancreatitis and gastric cancer, it was found that early autologous bile (gastric juice) reinfusion is beneficial to the recovery of the function and structure of the gastrointestinal tract and helps to maintain the integrity of the intestinal mucosa It can protect the intestinal mucosal barrier, significantly reduce the occurrence of enterogenous infection, and significantly improve abdominal surgery and the recovery of abdominal viscera function. Bile reinfusion after biliary surgery is a change from the traditional way of drainage outside the "T" tube after biliary surgery, and a combination of drainage and reinfusion is adopted. Infuse bile into the duodenum to avoid a large loss of body fluids, electrolytes, and digestiv...

AI Technical Summary

Problems solved by technology

Because the taste of bile is bitter and difficult to swallow, it is difficult for the patient to accept it, and the bile is alkaline, and bile reinfusion by gastric tube or oral bile can cause irritation to the stomach; and indwelling nasoenteric tube and jejunostomy can directly infuse bile into the intestinal tract, but The extracorporeal bile reflux device in the prior art generally requires special personnel to be on duty for drainage, and it can complete the extracorporeal reflux to a certain extent. However, due to the need for manual on-duty and greater dependence on personnel, it will be difficult to achieve timely and effective reinfusion to a certain extent. It is difficult to control and the waste of bile is also serious, and the practicality is limited to a certain extent

In addition, due to the patient's own factors, the amount of bile drainage in the body is different. If the equivalent is small, the effective time of bile in vitro is 4-5 hours. If it is not reinfused in time, it will cause a certain amount of waste. There are bacteria, crystals, bile sand, fibrous secretions, etc. in the bile. If the bile is not heated, filtered, sterilized, etc., the effectiveness of its reinfusion into the duodenum will be affected to a certain extent.
