Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to an adjustable negative pressure pancreatic juice drainage device. Background Technology

[0002] Pancreatic fistula surgery is a treatment for the dangerous condition of pancreatic fistula, where digestive juices secreted by the pancreas leak out through an abnormal channel. This usually occurs after pancreatic surgery or during the course of pancreatic disease. Pancreatic juice contains digestive enzymes that not only digest food but also have a corrosive effect on surrounding normal organs and tissues. Therefore, pancreatic fistula is a very dangerous condition that can lead to serious complications such as inflammation, bleeding, and infection. After pancreatic fistula surgery, a large amount of pancreatic juice is often present, requiring medical staff to drain it using a negative pressure pancreatic juice drainage device.

[0003] Currently, existing negative pressure pancreatic fluid drainage devices mainly include a main drainage tube with drainage holes, a Y-shaped negative pressure connecting tube, and a flushing shunt tube. When flushing is required, an external syringe is connected through the flushing shunt tube to inject water into the patient's abdominal cavity for flushing. When negative pressure aspiration of pancreatic fluid is required, a suction tube is inserted from the negative pressure connecting tube into the main drainage tube. The inserted suction tube is fixed and glued with medical tape, and pancreatic fluid is extracted by a negative pressure machine connected to the suction tube.

[0004] However, in the above-mentioned device, the drainage tube needs to be inserted into the abdominal cavity to come into contact with pancreatic juice, so that the suction tube and the negative pressure connecting tube come into contact with the abdominal cavity through the connection part of the medical tape. The adhesive in the tape is made of synthetic rubber, which may contain toxic and harmful substances, and can easily cause abdominal cavity contamination. Moreover, the tape needs to be wrapped and bonded in multiple turns, making installation and disassembly relatively troublesome.

[0005] Therefore, an adjustable negative pressure pancreatic juice drainage device needs to be designed to solve the problem. Utility Model Content

Detailed Implementation

[0021] Example 1, by Figure 1-4 An adjustable negative pressure pancreatic fluid drainage device is provided, including a drainage main tube 1, with multiple drainage ports 11 at the tail end of the drainage main tube 1, and a flushing diversion tube 3 and a negative pressure connecting tube 2 connected to the head end of the drainage main tube 1. A suction tube 5 is inserted into the opening of the negative pressure connecting tube 2, and a connecting device 4 is provided between the negative pressure connecting tube 2 and the suction tube 5 to limit the flow.

[0022] Specifically, the rubber drainage tube 1 is inserted into the patient's abdominal cavity to contact the pancreatic fluid. The negative pressure connecting tube 2 and the flushing shunt tube 3 are located externally. When flushing is required, an external syringe is connected through the flushing shunt tube 3 to inject water into the patient's abdominal cavity for flushing. Then, the connecting device 4 is installed on the negative pressure connecting tube 2. When negative pressure is needed to aspirate pancreatic fluid, the suction tube 5 is inserted from the negative pressure connecting tube 2 into the drainage tube 1. The suction tube 5 is fixed and limited by the connecting device 4. The suction tube 5 is connected to the external negative pressure unit. Pancreatic fluid enters from multiple drainage ports 11. The suction tube 5 draws out the pancreatic fluid. As the amount of pancreatic fluid decreases after aspiration, the negative pressure of the suction tube 5 can be adjusted through the connecting device 4.

[0023] In this embodiment, the connecting device 4 includes an adjusting cylinder 41. The bottom of the adjusting cylinder 41 is fixedly connected to a connecting sleeve 43. The adjusting cylinder 41 is inserted into and connected to the negative pressure connecting pipe 2 through the connecting sleeve 43. An adjusting bolt 44 is threadedly connected to the middle of the adjusting cylinder 41. The adjusting bolt 44 is threaded through the adjusting cylinder 41 and connected to a limit block that contacts the suction tube 5. A limit structure 42 is provided at the top of the adjusting cylinder 41.

[0024] Specifically, the negative pressure connecting tube 2 is fitted onto the connecting sleeve 43 of the adjusting cylinder 41. When the suction tube 5 is inserted, it passes through the limiting structure 42, the adjusting cylinder 41, and the connecting sleeve 43 into the negative pressure connecting tube 2. After the suction tube 5 is fully inserted, the limiting structure 42 fixes and limits the suction tube 5, effectively preventing the suction tube 5 from shaking or shifting during operation. During operation, the operator can rotate the adjusting bolt 44 to move the limiting block inside the adjusting cylinder 41 and deform the suction tube 5. When there is a lot of pancreatic fluid, the deformation of the suction tube 5 by squeezing reduces the tube diameter, increases airflow resistance, and relatively increases the negative pressure. As the amount of pancreatic fluid absorbed decreases, the operator can rotate the adjusting bolt 44 to move the limiting block inside the adjusting cylinder 41 and separate it from the suction tube 5, increasing the tube diameter of the suction tube 5, reducing airflow resistance, and relatively decreasing the negative pressure. This allows for the continued extraction of a smaller amount of pancreatic fluid while effectively preventing excessive negative pressure suction from damaging the mucosa, greatly improving safety.

[0025] In this embodiment, the adjusting cylinder 41, the limiting structure 42, the connecting sleeve 43, and the adjusting bolt 44 are all made of one of PVC, PE, PP, and PU. The connecting device 4 is made of disposable medical plastic material, which is less likely to cause adverse reactions when in contact with the human body and has high hygiene and safety.

[0026] The flushing diversion pipe 3 is equipped with a check valve structure to effectively prevent liquid backflow and air from entering the abdominal cavity.

[0027] In Embodiment 2, based on Embodiment 1, the limiting structure 42 includes a connecting sleeve 422 that is fixedly connected to the adjusting cylinder 41. A limiting sleeve 421 is fitted onto the outside of the connecting sleeve 422. The top of the connecting sleeve 422 has multiple slots 4221. The upper part of the connecting sleeve 422 is divided into multiple abutments through the multiple slots 4221. Each abutment has an abutment block 4222 fixed on its inner surface.

[0028] Specifically, when the suction tube 5 is inserted, it enters the negative pressure connecting tube 2 through the connecting sleeve 1 422, the adjusting cylinder 41 and the connecting sleeve 2 43. After the suction tube 5 is fully inserted, it is grasped and slid upward by the limiting sleeve 421. It is divided into multiple open abutments by multiple slots 4221 and then closed. The part connected with the abutment block 4222 comes into contact with the suction tube 5, thereby fixing and limiting the suction tube 5 and effectively preventing the suction tube 5 from shaking or shifting during operation.

[0029] In this embodiment, the multiple abutments on the connecting sleeve 422 are arranged in a ring and spread outwards, so that the multiple abutments that are spread outwards when the suction tube 5 is inserted will not easily affect the insertion of the suction tube 5.

[0030] In this embodiment, the top of the limiting sleeve 421 has a limiting ring, and the limiting ring is divided by multiple slots 4221. When the limiting sleeve 421 slides upward, it contacts and limits the movement of the limiting ring.

[0031] Working principle:

[0032] In use, the rubber drainage tube 1 is inserted into the patient's abdominal cavity to contact the pancreatic fluid. The negative pressure connecting tube 2 and the flushing shunt tube 3 are located externally. When flushing is required, an external syringe is connected through the flushing shunt tube 3 to inject water into the patient's abdominal cavity for flushing. Then, the connecting device 4 is installed on the negative pressure connecting tube 2. When negative pressure is needed to aspirate pancreatic fluid, the suction tube 5 is inserted from the negative pressure connecting tube 2 into the drainage tube 1. The suction tube 5 is fixed and limited by the connecting device 4. The suction tube 5 is connected to the external negative pressure unit. Pancreatic fluid enters from multiple drainage ports 11. The suction tube 5 draws out the pancreatic fluid. As the amount of pancreatic fluid decreases after aspiration, the negative pressure of the suction tube 5 can be adjusted through the connecting device 4.

[0033] The negative pressure connecting tube 2 is fitted onto the connecting sleeve 43 of the adjusting cylinder 41. When the suction tube 5 is inserted, it passes through the connecting sleeve 422, the adjusting cylinder 41 and the connecting sleeve 43 and enters the negative pressure connecting tube 2. After the suction tube 5 is fully inserted, the limiting sleeve 421 is grasped and slid upward. It is divided into multiple open abutments by multiple slots 4221 and then closed. The part connected with the abutment 4222 contacts the suction tube 5, thereby fixing and limiting the suction tube 5 and effectively preventing the suction tube 5 from shaking and displacing during operation.

[0034] During operation, the staff can rotate the adjusting bolt 44 to move the limiting block inside the adjusting cylinder 41 and squeeze and deform the suction tube 5. When there is a lot of pancreatic fluid, the diameter of the suction tube 5 is reduced by squeezing and deforming it, which increases the airflow resistance and the negative pressure.

[0035] As pancreatic fluid is drawn down, staff can rotate the adjusting bolt 44 to move the limiting block inside the adjusting cylinder 41 and separate it from the suction tube 5. This increases the diameter of the suction tube 5, reduces airflow resistance, and lowers the negative pressure. This allows for the continued extraction of less pancreatic fluid while effectively preventing excessive negative pressure suction from damaging the mucosa, thus greatly improving safety.

[0036] In summary, the connecting device 4 is made of disposable medical plastic, which is unlikely to cause adverse reactions when in contact with the human body, has high hygiene and safety, and is easy to install and remove. It can fix and limit the suction of the suction tube 5 and adjust the suction force of the negative pressure drainage, making it highly practical.
