Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a combined adjustable flushable drainage tube. Background Art

[0002] After pancreatic surgery, pancreatic juice leakage often occurs. Due to the digestive characteristics of pancreatic juice itself, it causes local corrosion, leading to severe complications such as abdominal bleeding, infection, and even digestive tract perforation. In order to reduce the occurrence of this situation, local and sufficient drainage is particularly important. In view of the characteristics of pancreatic juice being viscous and difficult to flow, active flushing drainage came into being.

[0003] Patent No. 202220703426.3 discloses a patent for a double-lumen flushable drainage tube, which includes a drainage tube, a side tube for flushing, and a cut-off structure; the first end of the drainage tube is set to an opening that is not easy to block the tube during drainage, the side tube for flushing is set in the drainage tube, and the cut-off structure is set at the second end of the drainage tube, and the cut-off structure can cut off and seal the drainage tube. Although the present application can flush the drainage tube, it cannot limit the flow rate, and it is a double-lumen tube in one tube, which can easily cause the inner wall to be rough, resulting in poor drainage and blockage of the drainage tube. Summary of the invention

[0004] The utility model aims to provide a combined adjustable flushable drainage tube, which is used to solve the problems of poor drainage and poor flushing effect of the existing drainage tubes.

[0005] The technical solution of the utility model is as follows: the combined adjustable flushable drainage tube comprises a main drainage tube 1, a flushing tube 2, and an adjusting device 3, wherein the main drainage tube 1 is connected to the flushing tube 2, the adjusting device 3 is installed on the flushing tube 2, and a plurality of holes are arranged on the side of the main drainage tube 1 away from the adjusting device 3. The front ends of the main drainage tube and the flushing tube are provided with a plurality of holes.

[0006] The side wall of the main drainage tube 1 is provided with a groove 4, and the side wall of the flushing tube 2 is provided with a convex strip 5, and the convex strip 5 cooperates with the groove 4 to form a mortise and tenon structure connection.

[0007] The length of the flushing tube 2 is greater than that of the main drainage tube 1 .

[0008] The main drainage tube 1 has a lumen of about 8 mm, a tube wall thickness of about 1 mm, and about 6-7 side holes at the top.

[0009] The lumen of the flushing tube 2 is about 3-5 mm, and the tube wall is about 0.5 mm.

[0010] The utility model has the following beneficial technical effects: a hole is provided on the side of the main drainage tube 1, through which the local viscous liquid can be actively diluted to fully drain the local area. No one tube with two cavities is used, and the old-fashioned flushing drainage tube design is avoided, where a large tube is placed inside a small tube, causing the inner wall to be rough, resulting in poor drainage and blockage of the drainage tube. The flushing tube inside the drainage tube wall is avoided, and the flushing tube is too thin due to the limitation of the wall thickness, resulting in low flushing efficiency. The main drainage tube and the flushing tube are connected by mortise and tenon joints to avoid the phenomenon of loose connection and easy tube detachment. The gap at the joint of the two tubes is too large, and the greater omentum or other tissues enter to cause the risk of internal hernia. An adjustment device is installed on the flushing tube to adjust the water inlet speed. The two tubes can be combined with flushing tubes of different calibers according to actual conditions, and combined on-site for local treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0017] See also Figure 1-3 The combined adjustable flushable drainage tube comprises a main drainage tube 1, a flushing tube 2, and an adjusting device 3, wherein the main drainage tube 1 and the flushing tube 2 are connected by a mortise and tenon structure, the adjusting device 3 is installed on the flushing tube 2, and 6-7 holes are arranged on the side of the main drainage tube 1 away from the adjusting device 3. The length of the flushing tube 2 is greater than that of the main drainage tube 1.

[0018] The main drainage tube 1 has a lumen of about 8 mm, a tube wall thickness of about 1 mm, and about 6-7 side holes at the top. Adding side holes enhances the drainage effect of the main drainage tube 1.

[0019] The lumen of the flushing tube 2 is about 3-5 mm, and the tube wall is about 0.5 mm.

[0020] The main drainage tube 1 is made of rubber material, which enhances the fit between the main drainage tube 1 and human tissue and reduces the leakage rate.

[0021] When in use, the front end of the main drainage tube 1 is inserted into the patient's body, and the top end of the flushing tube 2 is closed by the closing cap, or the flushing tube 2 with a closed front end is selected, and then the main drainage tube 1 and the liquid collecting bag are circulated through the connector. When the liquid collecting bag needs to be replaced, the connection between the liquid collecting bag and the connector is disconnected, and after the new liquid collecting bag is connected, the liquid continues to be drained into the liquid collecting bag; when the patient needs to perform a flushing operation, the connection between the liquid collecting bag and the connector is disconnected, and the closing cap is opened. The infusion device is connected through the flushing tube 2 to flush the patient's chest or abdominal cavity. The water inlet speed is adjusted by the regulating device 3. After the flushing is completed, drainage is performed through the connector and the liquid collecting bag.
