AI Technical Summary
In the existing abdominal flushing tube, the drain port of the drain tube is too close to the outlet of the main pipe, which causes the normal saline to be pulled out before rinsing the tissue, affecting the flushing effect; the drain tube may be close to the tissue, resulting in poor fluid discharge.
The top of the main pipe of the abdominal cavity flushing tube is designed to form two separate arc cavity cavity and an isolated drainage cavity. The arc cavity outlet is to both sides. The drainage cavity is connected to the drainage tube. The direction of the drainage port and the outlet is different. The drainage cavity is designed to avoid being close to the tissue and form a reserved space.
Ensure that normal saline effectively rinse the tissue, avoid poor fluid output, and improve the rinse effect and efficiency.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medical consumables, and particularly relates to an abdominal irrigation tube. Background Art
[0002] An abdominal irrigation tube is a medical device used for abdominal irrigation or drainage. It is usually made of plastic and is tubular as a whole. The rear part has a connector. It is inserted into the abdominal cavity and connected to an infusion set or a drainage bag. The main function of the abdominal irrigation tube is to remove substances such as blood, pus, and bile in the abdominal cavity to relieve the pressure and inflammatory reaction in the abdominal cavity. It can also be used for wound drainage after surgery and the treatment of intra-abdominal infections.
[0003] The abdominal irrigation tube includes a main tube for water inlet, and a thinner drainage tube inside the main tube. The end of the main tube is open as a water outlet. Normal saline is injected into the abdominal cavity through the main tube, and at the same time, the drainage tube is opened to draw out the irrigation fluid in the form of negative pressure. There are two obvious problems with the existing abdominal irrigation tubes: First, the drainage opening of the drainage tube is very close to the water outlet of the main tube, so that a large amount of normal saline is drawn out before flushing the tissue, affecting the flushing effect; Second, during use, the drainage opening of the drainage tube is very close to the tissue, and even under the action of negative pressure, it may be close to the tissue, resulting in poor drainage. Summary of the Utility Model
[0004] In view of the above problems, the purpose of the utility model is to provide an abdominal irrigation tube, aiming to solve the above technical problems.
[0005] The utility model adopts the following technical solutions:
[0006] The abdominal irrigation tube includes a main tube and a drainage tube located inside the main tube. Two separated arc-shaped cavities are formed at the top of the main tube. An inward depression is formed between the two arc-shaped cavities to form an isolated drainage cavity. Each arc-shaped cavity is provided with a water outlet facing outward. A drainage opening is provided on the surface of the drainage cavity. The top end of the drainage tube is communicated with the drainage cavity. A connector is further installed at the end of the main tube, and a water inlet pipe is provided on the connector.
[0007] Further, the drainage openings are distributed on the upper and lower surfaces and the front end of the drainage cavity.
[0008] Further, the connector is successively a plug-in part, a flaring part, a sealing part, and a connecting part from front to back. The water inlet pipe is arranged on the flaring part. A sealing round hole matching the drainage tube is opened at the center position of the sealing part. The end of the drainage tube passes through the sealing round hole.
[0009] The beneficial effects of the present utility model are as follows: This structure forms three isolated cavities at the top of the main pipe, including two arc-shaped cavities and one drainage cavity. The arc-shaped cavities are communicated with the main pipe, the water outlets of the arc-shaped cavities are arranged on both sides, and the drainage cavity in the middle is connected with the drainage pipe; in this structure, the direction of the drainage opening of the drainage cavity is different from the direction of the water outlet of the main pipe, so there is no situation where the physiological saline for cleaning fails to reach and is directly pumped out during flushing; on the other hand, the drainage cavity in the middle is designed to be sunken, and the drainage opening will not be in close contact with the intra-abdominal tissues, forming a reserved space, which is convenient for pumping out the flushing liquid and will not cause problems such as poor liquid discharge.

[0014] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0015] In order to illustrate the technical solutions described in the present utility model, the following is illustrated through specific embodiments.
[0016] As Figures 1-3 shown, the abdominal cavity irrigation tube provided by this embodiment includes a main pipe 1 and a drainage pipe 2 located inside the main pipe 1. Two separated arc-shaped cavities 3 are formed at the top of the main pipe 1. An inward depression is formed between the two arc-shaped cavities 3 to form an isolated drainage cavity 4. Each arc-shaped cavity 3 is provided with a water outlet 31 facing outward. A drainage opening 41 is formed on the surface of the drainage cavity 4. The top end of the drainage pipe 2 is communicated with the drainage cavity 4. A connection head 5 is further installed at the end of the main pipe 1, and a water inlet pipe 51 is provided on the connection head 5.
[0017] In this structure, the main pipe part of the abdominal cavity irrigation tube has two connected arc-shaped cavities. The outer wall of the arc-shaped cavity is provided with water outlets. Therefore, after the water inlet pipe of the main pipe accesses physiological saline, it flushes out to both sides from the water outlets. The drainage cavity located between the two arc-shaped cavities is designed in a sunken shape and is isolated from the arc-shaped cavities. The drainage openings of the drainage cavity are distributed on the upper and lower surfaces and the front end of the drainage cavity. Therefore, the direction of the drainage openings of the drainage cavity is different from that of the water outlets of the main pipe, so there is no situation where the physiological saline for cleaning is directly drawn out without being flushed, ensuring the flushing effect.
[0018] In addition, the middle drainage cavity is designed in a sunken shape, and the drainage openings will not be in close contact with the intra-abdominal tissues, forming a reserved space, which is convenient for drawing out the flushing fluid and will not cause problems such as poor drainage.
[0019] Further, as a specific structure of the connector, in combination with Figure 4 As shown in the figure, the connector 5 from front to back is successively a plug-in part 52, a flaring part 53, a sealing part 54 and a connecting part 55. In the figure, the diameter of the flaring part 53 is larger than that of the plug-in part 52. The plug-in part is inserted into the end of the main pipe. The figure shows an inner insertion form, and an outer insertion form can also be adopted. In order to ensure the sealing between the two, a sealing ring can be added between them to ensure the sealing effect. Of course, they can also be directly fixed with sealant. The water inlet pipe 51 is arranged on the flaring part 53. A sealing round hole 56 matching the drainage tube 2 is opened at the center position of the sealing part 54, which also ensures the sealing performance. The end of the drainage tube 2 passes through the sealing round hole 56 and is connected to the negative pressure drainage and flushing system through the connecting part 55 to lead the flushing fluid out of the drainage tube into the drainage bag.
[0020] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
