Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an anti-clogging drainage tube. Background Art

[0002] A tumor is a neoplasm formed by the proliferation of localized tissue cells in response to various tumorigenic factors. Because these neoplasms often appear as space-occupying, mass-like protrusions, they are also called neoplasms. Liver cancer and pancreatic cancer, both known as the "kings of cancer," are highly malignant tumors. Cancer patients often require a chest drainage tube after surgery to drain fluid, blood, pus, and gas from the chest, preventing infection and potentially affecting wound healing.

[0003] However, during use, the existing anti-clogging drainage tube is located inside the human body and is easily squeezed by tissue movement. At the same time, there are objects such as liquid, blood and pus in the drainage tube, which are easy to accumulate together and cause the drainage hole to be blocked, thereby affecting the normal use of the drainage tube. For this reason, we propose an anti-clogging drainage tube. Utility Model Content

[0022] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0023] Example:

[0024] See also Figure 1 - Figure 6 A blockage-resistant drainage tube includes a drainage tube 1 and a liquid collecting bag 2. The liquid collecting bag 2 is provided on the right side of the drainage tube 1, a cleaning component 3 is provided inside the drainage tube 1, and a connecting component 4 is provided on the outer wall of the drainage tube 1. The drainage tube 1 is connected to the liquid collecting bag 2 through the connecting component 4.

[0025] By rotating the brake disc 37, the brake disc 37 drives the brake rod 35 to rotate in the through hole 34. At the same time, the brake rod 35 synchronously drives the blade 33 to rotate in the drainage tube 1, and the blade 33 breaks up the blocked part in the drainage tube 1. By rotating the blade 33 to a straight line state, the drainage tube 1 can be circulated, effectively preventing objects from accumulating in the drainage tube 1 when in use, causing the drainage tube 1 to be blocked and unusable.

[0026] In other embodiments, the cleaning assembly 3 includes a rotating groove 31 provided on the inner wall of the drainage tube 1, a rotating rod 32 is rotatably connected in the rotating groove 31, a blade 33 is provided on the top of the rotating rod 32, a through hole 34 is provided on the inner wall of the drainage tube 1 corresponding to the top of the blade 33, a brake rod 35 is provided on the surface of the blade 33 in the through hole 34, the outer wall of the brake rod 35 is tightly fitted with the inner wall of the through hole 34, a ratchet 36 is provided on the outer wall of the brake rod 35, a brake disc 37 is provided on the top of the brake rod 35, a fixing seat 38 is provided on the surface of the drainage tube 1 on the left side of the brake disc 37, a movable rod 39 is rotatable in the fixing seat 38, a torsion spring 310 is wound on the movable rod 39, a bracket 311 is provided on the outer wall of the movable rod 39, and an insertion rod 312 is provided on the bottom end surface of the bracket 311;

[0027] At this time, the torsion spring 310 will drive the movable rod 39 to return to its original position and rotate in the fixed seat 38, and cause the plug rod 312 to rotate into another set of tooth grooves on the ratchet 36, thereby achieving the purpose of limiting the blade 33.

[0028] In other embodiments, a groove is formed on the front surface of the insertion rod 312, and the groove is designed in a C-shape;

[0029] This design can prevent the medical staff from slipping when rotating the insertion rod 312.

[0030] In other embodiments, the brake disc 37 is welded to the surface of the brake rod 35 on the side facing away from the drainage tube 1, and the surface of the brake disc 37 is provided with anti-slip textures;

[0031] This design can increase the friction between the medical staff's hands and the brake disc 37, thereby ensuring the medical staff's stability in using the brake disc 37 and preventing their hands from slipping.

[0032] In other embodiments, the connecting assembly 4 includes a movable chamber 41 provided on the front and rear end surfaces of the drainage tube 1, a spring 42 is provided on the inner wall of the movable chamber 41, and the other end of the spring 42 is connected to a slide rod 43, which slides in the movable chamber 41. The outer wall of the slide rod 43 is provided with a connecting plate 44, and the surface of the connecting plate 44 facing the drainage tube 1 is provided with multiple groups of limiting rods 45, and the outer ends of the limiting rods 45 are provided with limiting grooves 46 on the surface of the liquid collecting bag 2 corresponding to the corresponding surfaces;

[0033] When in use, first pull the two sets of connecting plates 44 in the direction away from the drainage tube 1, so that the connecting plates 44 drive the slide rod 43 to slide in the movable compartment 41 and stretch the spring 42. At the same time, the connecting plates 44 synchronously drive the limit rod 45 to slide out of the limit groove 46, and then remove the liquid collecting bag 2 from the drainage tube 1. When the liquid collecting bag 2 needs to be installed, the drainage tube 1 is fitted with the liquid collecting bag 2, and the limit groove 46 on the liquid collecting bag 2 is aligned with the limit rod 45. Then, by loosening the connecting plates 44, the elastic force of the spring 42 is used to drive the slide rod 43 to reset and slide in the movable compartment 41, and the slide rod 43 drives the limit rod 45 through the limit groove 46 through the connecting plates 44, so as to achieve the purpose of installing the liquid collecting bag 2.

[0034] In other embodiments, one end of the spring 42 is welded to the inner wall of the movable chamber 41 , and the other end of the spring 42 is welded to the inner wall of the slide rod 43 ;

[0035] Through this design, the connection strength between the spring 42 and the movable compartment 41 and the slide rod 43 can be increased, preventing the spring 42 from loosening in the movable compartment 41, resulting in uneven force output by the spring 42 to both sides of the slide rod 43, which can easily cause the slide rod 43 to be stuck in the movable compartment 41 and unable to slide.

[0036] In other embodiments, two sets of limiting rods 45 are provided. Both sets of limiting rods 45 are rectangular in design. The limiting grooves 46 are formed as through holes adapted to the limiting rods 45 . The limiting grooves 46 penetrate the liquid collection bag 2 and extend to the surface of the drainage tube 1 .

[0037] This design can increase the number of engagement points between the limit rod 45 and the liquid collecting bag 2, preventing a large gap between the liquid collecting bag 2 and the drainage tube 1, which would cause the liquid in the drainage tube 1 to fall to the ground and pollute the surrounding environment.

[0038] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
