Description

Technical Field

[0001] The present invention belongs to the technical field of bile drainage and reinfusion, and particularly relates to a bile drainage and reinfusion device. Background Art

[0002] With the continuous in-depth understanding of severe acute pancreatitis and the biological behavior of gastric cancer, it is found that early autologous bile (gastric juice) reinfusion is beneficial to the recovery of gastrointestinal function and structure, helps to maintain the integrity of the intestinal mucosa, protects the intestinal mucosal barrier, can significantly reduce the occurrence of intestinal source infection, and has an obvious improvement effect on abdominal surgery and the recovery of abdominal visceral organ function.

[0003] In the prior art, for patients with long-term placement of nasobiliary tubes for biliary tract tumors, the amount of bile drained daily is relatively large, especially for high bile drainage volume, resulting in a large loss of body fluid and water. Due to long-term bile outflow, patients are prone to loss of appetite, diarrhea, disorders of water and electrolyte and acid-base balance, and insufficient circulating blood volume, etc., which affect the digestion of fat and the absorption of fat-soluble vitamins, affect postoperative recovery, and prolong the hospital stay and increase costs. While reinfusing bile into the duodenum can avoid a large loss of body fluid, electrolytes, digestive juices, etc., correct electrolyte disorders, promote appetite, and accelerate the postoperative recovery of patients.

[0004] In the existing bile reinfusion devices, first, the drained bile needs to be collected from the drainage bag into a container, then the bile is filtered using a sterile gauze, and then the filtered bile is collected into another container to connect an infusion set, and the bile is input through a nasointestinal tube or a jejunostomy tube. And during the operation, the bile may be contaminated by bacteria, and it is not kept at a constant temperature state, and the risk for medical staff to contact the patient's body fluid is relatively large, which is not conducive to self-protection technical problems.

[0005] Chinese Patent with application number 201710907318.1 discloses a disposable closed bile drainage and reinfusion device, including a drainage tube 1, an umbrella-shaped Murphy's drip tube 2, a collection bag 3 and a transition tube 5. Among them, the front end of the umbrella-shaped Murphy drip tube 2 is connected to the drainage tube 1, the rear end of the umbrella-shaped Murphy drip tube 2 is connected to one end of the transition tube 5, and the other end of the transition tube 5 is connected to the collection bag 3, and the whole constitutes a closed drainage and reinfusion device. This can make the bile collection and reinfusion process a closed operation, reduce the iatrogenic pollution of bile and the pollution of bile to the surrounding environment and operators, and provide two-way protection for patients and medical staff. However, in this technical solution, there is a lack of filtration of bile, and at the same time, it is not kept at a constant temperature state. Therefore, it needs to be improved.

During use, the bile in the drainage bag 2 passes through the filtering mechanism 5 and the heating mechanism 4 in the sealing cylinder 3 for filtration and heating in sequence, and then is re-infused into the patient's body through the re-infusion tube 6. By filtration, impurities entering the patient's body are reduced, and by heating the bile, the discomfort caused by the entry of low-temperature bile into the human body is reduced, and the activity of enzymes in the bile is maintained.

In this embodiment, when the thick filtering tube 514 is blocked, after disassembling the device, by pressing the first disc 511 and the second disc 512, the thin filtering tube 515 fixed thereon enters the inner hole of the thick filtering tube 514 for alignment and dredging. And through the arranged spring ring 513, the pressing is limited to avoid damage caused by excessive pressure.

The water in the heating layer 41 is preheated to a set temperature under the action of the electric heating rod 42, and the bile entering it is heated through water bath heating, improving the uniformity of the bile heating temperature. At the same time, the water temperature is easy to control and the control accuracy is higher. Moreover, the water bath heating of bile is relatively gentle, avoiding the change of the nature of bile due to direct heating.

[0033] It should be noted that in this embodiment, in order to achieve adjustable rate during bile reinfusion, a speed regulating valve 7 is added to the reinfusion tube 6. The speed regulating valve 7 is preferably a direct application of the infusion flow rate regulator in the prior art. During use, the rate of bile reinfusion is adjusted by sliding the roller on the infusion flow rate regulator. Embodiment Two

The filtration of the bile is realized through one-time filtration, which is convenient and fast.

[0040] Another filtration method is to open the second control valve 15, open the first control valve 10 and the circulation pump 9. After the bile passing through the filtration mechanism 5 is initially filtered, the filtrate is input into the heating mechanism 4 through the first filtrate tube 12 and the second filtrate tube 13 for heating. At the same time, the circulation pump 9 circulates and filters the bile in the filtration mechanism 5, increasing the filtration of the bile.

The water in the outer cylinder 43 has been heated to a preset temperature, preferably 37 - 38 degrees Celsius, by the electric heating rods 42 before the bile enters. At this time, the motor is started to drive the rotating cylinder 46 and the arc-shaped pieces 47 thereon to rotate, so as to stir the bile in the inner cylinder 44 through the arc-shaped pieces 47, realizing uniform heating and improving the heating rate. At the same time, through the arranged sealing ring, the bile is prevented from entering the inside of the rotating cylinder 46.
