Description

Technical Field

[0001] The utility model relates to a drainage tube. Background Art

[0002] Chinese utility model patent CN211724154U discloses a drainage tube, the tube body of which includes a first tube body and a second tube body. The cross-section of the first tube body is designed as a cross, and the first tube body includes a cross rib located in the middle and an arc-shaped wall independently provided at the end of the cross rib. The cross rib of the second tube body is designed as a ring. The cross rib at the lower end of the first tube body extends into the second tube body and forms a connecting section with the second tube body. The connecting section is connected to the first tube body and the second tube body respectively in an arc shape. The outer diameter of the first tube body and the outer diameter of the second tube body are both smaller than the outer diameter of the connecting section. This cross-rib-shaped support structure of the first tube body can prevent the drainage tube from being flattened when entering the human body. The existing drainage tubes also have the following disadvantages: 1. The tube body is divided into a connecting section, a first tube body, and a second tube body, and the three need to be connected in an arc shape. The outer diameter of the first tube body and the outer diameter of the second tube body are both smaller than the outer diameter of the connecting section, which makes the tube body molding process very complicated and the structure is also complicated; 2. The function is single and can only achieve the function of draining waste liquid. Summary of the Invention

The ends of the supporting ribs have curved walls. A supporting rib and its curved arms at the ends constitute a flow guide. The space between adjacent flow guides forms an inlet flow channel. The rear end of each flow guide is integrated with the second tube body.

[0006] The second tube body is provided with an axially extending outlet flow channel, the front end of the outlet flow channel is connected to each inlet flow channel, and the rear end of the outlet flow channel extends to the rear end surface of the second tube body to form a through passage;

[0007] At least one of the flow guide members is further provided with an axial functional channel, which extends forward to the rear end of the second tube body to form a through passage.

[0008] Furthermore, each of the two flow-guiding members is provided with an axial functional channel.

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0017] Reference Figures 1-4 A multifunctional drainage tube includes a tube body, wherein the tube body includes a first tube body 1 at the front section and a second tube body 2 at the rear section, and the first tube body 1 and the second tube body 2 are integrated.

[0018] The first tube body 1 has a central column 3, which is formed by extending forward from the front end of the second tube body 2. At least two support ribs 4 extend outward from the central column 3, and the end of the support rib 4 has an arc-shaped wall 5. A support rib 4 and the arc-shaped arm 5 at its end constitute a drainage piece. The space between adjacent drainage pieces forms an inlet flow channel 6, and the rear end of each drainage piece is integrated with the second tube body 2.

[0019] The second tube body 2 is provided with an axially extending outlet channel 7, the front end of the outlet channel 7 is connected to each inlet channel 6, and the rear end of the outlet channel 7 extends to the rear end surface of the second tube body 2 to form a through passage, and the waste liquid from the affected area flows through the inlet channel 6 to the outlet channel 7 and is finally discharged.

[0020] In the above structure, although the parts of the tube body are described as the "first tube body" and the "second tube body" respectively, it is actually a single tube body formed in one piece, which has a simple structure and is easy to form.

[0021] At least one drainage member is also provided with an axial functional channel 8, which extends forward to the rear end of the second tube body 2 to form a through passage. Through this functional channel 8, other functions can be achieved, such as being used as a flushing channel, through which physiological saline or drugs are injected into the affected area for flushing and disinfection.

[0022] Of course, multiple functional channels 8 can also be provided to achieve other functions, that is, an axial functional channel is provided in each of the two guide members.

[0023] In one embodiment, the drainage member includes a first drainage member, a second drainage member, and a third drainage member. The width of the first drainage member is greater than the width of the second drainage member and the width of the third drainage member. An axial functional channel 8 is provided in the first drainage member, and another functional channel 8 is provided in the second drainage member or the third drainage member. The functional channel in the first drainage member with a larger width can have a larger channel diameter. When operations such as flushing and disinfection with a larger flow rate are required, operations can be performed through the functional channel with a larger diameter.

[0024] In the case of three flow guide members, there are three inlet flow channels 6 . In this case, the cross section of the outlet flow channel 7 is crescent-shaped so as to be smoothly connected with the three inlet flow channels 6 .

[0025] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0026] The above describes the implementation methods of the present invention. However, the present invention is not limited to the above implementation methods. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
