Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical devices, and in particular to a connecting tube for connecting a drainage bag and a single J tube. Background Art
[0002] As a soft tubular device, the single-J tube, also known as the pigtail tube, is an interventional device that is widely used in clinical practice. Some patients with peritoneal effusion, hydronephrosis, abscesses and other diseases need to have a single-J tube placed in their bodies to drain the effusion. The single-J tube is used to drain the effusion in the patient's abdominal cavity, thoracic cavity, and pericardium to the outside of the body and is collected in a drainage bag. According to diagnosis and treatment standards, the single-J tube can be left in the patient's body for 3 months, but the drainage bag needs to be replaced at least once a week to avoid bacterial infection or fluid overflow.
[0003] However, in general, the size of the drainage bag connecting tube can be a standard medical device tubing size, such as a diameter of 3mm, 4mm or 5mm. These sizes are generally suitable for common drainage bags, which are used to drain body fluids, such as urine or other drainage fluids. In addition, the size of the drainage bag connecting tube may also vary due to different types of drainage requirements. For example, the drainage bag used in chest drainage may have a larger tubing size to cope with the need to discharge a larger amount of drainage fluid. Therefore, the output tubing of a single J tube cannot be adapted to drainage bags of various sizes. Incompatible tubing connections will result in a loose connection between the two, which is often easy to fall off; if the tape is forcibly fixed and sealed, it will make the tape difficult to tear off, and the drainage bag and the single J tube will be difficult to separate, making it inconvenient for patients to replace the drainage bag by themselves at home.

[0026] In addition, the technical features involved in the different embodiments of the utility model described above can be combined with each other as long as they do not conflict with each other.
[0027] The utility model provides Figure 1 , Figure 2 , Figure 3 As shown, a connecting tube for connecting a drainage bag and a single J tube 2 is used to connect the drainage bag and the single J tube 2 so that the two are connected and sealed. Its main structure includes: a connecting tube body 1, and the two ends of the connecting tube body 1 are respectively provided with a first opening 11 and a second opening 12, and the first opening 11 and the second opening 12 are mutually connected; the first opening 11 and the second opening 12 can be straight or curved, that is, the connecting tube body 1 can be a straight or curved columnar structure. Specifically, the first opening 11 and the second opening 12 are respectively arranged at the two ends of the extension direction of the connecting tube body 1. A first connecting tube portion 13 is arranged on the end of the connecting tube body 1 close to the first opening 11, and the first connecting tube portion 13 is used to connect the drainage bag connecting tube 3. A second connecting tube portion 14 is provided at one end of the connecting tube body 1 close to the second opening 12, and the second connecting tube portion 14 is used to connect the single J tube 2; wherein, the first connecting tube portion 13 is spliced together by a plurality of connecting sleeves 131 with different outer diameters, and the plurality of connecting sleeves 131 are connected in sequence according to the outer diameter sizes, and the outer diameter of the first connecting tube portion 13 increases step by step toward the second opening 12.
[0028] It should be noted that, in general, the size of the drainage bag connecting tube 3 can be a standard medical device pipeline size, such as a diameter of 3mm, 4mm or 5mm. These sizes are usually suitable for common drainage bags, which are used to drain body fluids, such as urine or other drainage fluids. In addition, the size of the drainage bag connecting tube 3 may also vary due to different types of drainage requirements. For example, the drainage bag used in thoracic drainage may have a larger pipeline size to cope with the need to discharge a larger amount of drainage fluid. Therefore, the output pipeline of a single J tube 2 cannot be adapted to drainage bags of various sizes, and an incompatible pipeline connection will result in a loose connection between the two, which is often easy to fall off; if the tape is forcibly fixed and sealed, it will cause the tape to be difficult to tear off, and the drainage bag and the single J tube 2 are difficult to separate, which is inconvenient for patients to replace the drainage bag at home.
[0029] The first connecting pipe portion 13 of the present invention is formed by combining a plurality of connecting sleeves 131 with gradually increasing outer diameters, such as Figure 2 , Figure 3 As shown. In one embodiment, the inner diameters of the plurality of connecting sleeves 131 are respectively set to 3.2 mm, 4.2 mm, and 5.2 mm. And the drainage bag connecting tube 3 with a diameter of 3 mm, 4 mm, or 5 mm can be connected accordingly. Since the drainage bag connecting tube 3 has a certain elasticity, its inner diameter has a certain expansion space. The inner diameters of the plurality of connecting sleeves 131 in this embodiment are not used as specific settings of the present application scheme. The inner diameters of the plurality of connecting sleeves 131 can also be set to other different sizes to correspond to the connection of different drainage bag connecting tubes 3.
[0030] It can be seen that the first connecting tube portion 13 of the present application scheme can be adapted to connect drainage bag connecting tubes with different aperture sizes through a plurality of connecting sleeves 131 with gradually increasing outer diameters, so that the single J tube 2 can be adapted to drainage bags of different models, and can effectively save the time for replacing the drainage bag, making it convenient for patients to replace the drainage bag by themselves.
[0031] Further, such as Figure 2 , Figure 3 As shown, the connecting sleeve 131 is provided with a plurality of sealing rubber rings 132 surrounding its outer side wall. It is understandable that the sealing rubber rings 132 surrounding the connecting sleeve 131 can effectively improve the sealing performance between the drainage bag connecting tube 3 and the connecting sleeve 131, thereby avoiding leakage caused by a gap between the two.
[0032] Further, such as Figure 2 As shown, a plurality of connecting sleeves 131 are provided with a chamfered portion 133 at one end close to the first opening 11, and the chamfered portion 133 is arranged around the end edge of the connecting sleeve 131. It can be understood that the chamfered portion 133 can guide the drainage bag connecting tube 3 to be smoothly inserted into the connecting sleeve 131. Specifically, the chamfered portion 133 can be configured as a straight cut or a smooth curved surface.
[0033] Further, such as Figure 2 As shown, the first connecting pipe part 13 is formed by integrally splicing a plurality of connecting sleeves 131 with different outer diameters. The plurality of connecting sleeves 131 are integrally formed, and the integrally formed structure can be produced by injection molding or the like. The production cost of the first connecting pipe part 13 is effectively reduced, and the structural strength of the first connecting pipe part 13 is improved.
[0034] Further, such as Figure 2 , Figure 3As shown, the second connecting pipe part 14 is configured as a sleeve structure, and the inner side wall of the sleeve structure is provided with an internal thread 141. The second connecting pipe part 14 is used to connect the single J pipe 2, and the second connecting pipe part 14 is threadedly connected with the external thread of the connecting end of the single J pipe 2 through the internal thread 141 of the sleeve structure, so that the two are tightly connected.
[0035] Further, such as Figure 2 As shown, the outer wall of the sleeve structure is provided with a plurality of anti-slip members 142, which extend along the length direction of the sleeve structure, and are evenly distributed on the outer wall of the sleeve structure. It can be understood that the anti-slip members 142 are used to enhance the friction force on the surface of the sleeve structure to prevent the finger skin from slipping with the surface of the sleeve structure. The second connecting tube portion 14 and the single J tube 2 can be smoothly separated or connected.
[0036] Further, such as Figure 2 As shown, the connecting tube body 1 is provided with a plurality of annular connecting rings 15 surrounding the outer side wall thereof, and grooves 16 are formed between adjacent annular connecting rings 15. It can be understood that the annular connecting rings 15 on the connecting tube body 1 and the grooves 16 formed between adjacent annular connecting rings 15 can effectively increase the friction force on the surface of the connecting tube body 1, so that the connecting tube body 1 can be smoothly connected or separated from the drainage bag connecting tube 3.
[0037] Furthermore, the connecting pipe body 1, the first connecting pipe portion 13 and the second connecting pipe portion 14 are integrally formed. It is understandable that the integrally formed structure can be produced by injection molding or the like, which effectively reduces the production cost of the connecting pipe body 1 and improves the structural strength of the connecting pipe body 1.
[0038] Furthermore, the connecting tube body 1 is a polyvinyl chloride (PVC) or polyethylene (PE) material structure. In the medical field, polyethylene is widely used to manufacture medical devices, surgical instruments, medical packaging, etc. PE materials are generally safe and non-toxic and harmless to the human body. PVC and PE are both common plastic materials, and they have important uses in the medical field.
[0039] In summary, the present application provides a connecting tube for connecting a drainage bag and a single J tube 2. The first connecting tube portion 13 of the utility model can be adapted to connect drainage bag connecting tubes with different aperture sizes through a plurality of connecting sleeves 131 with gradually increasing outer diameters, so that the single J tube 2 can be adapted to drainage bags of different models, and can effectively save the time for replacing the drainage bag, making it convenient for patients to replace the drainage bag by themselves.
[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
