Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an abdominal drainage bottle for digestive oncology. Background Technology

[0002] In the field of gastrointestinal oncology, the lesions are mostly located inside the abdominal cavity. After surgical treatment, there may be bleeding, effusion, and residual tissue fluid in the abdominal cavity. If these are not drained in time, they may lead to complications such as abdominal infection and adhesions, affecting the patient's postoperative recovery. Therefore, it is necessary to use an abdominal drainage bottle for drainage.

[0003] In current abdominal drainage practices, medical staff often have to attend to numerous patient matters, making it difficult to have someone constantly monitoring the drainage process. If negligence occurs, the drainage bottle may gradually accumulate until it is overfilled, or the bottle may accidentally tip over. On one hand, the overfilled drainage bottle can block the drainage tube, abruptly halting the drainage process and preventing the continuous and effective removal of fluid from the abdominal cavity, thus delaying the patient's recovery. On the other hand, and more seriously, if the bottle tip over, the accumulated drainage fluid is highly likely to flow back due to pressure differences and gravity. This backflow of drainage fluid, containing tissue exudate, potential pathogens, and even possible tumor cells, into the abdominal cavity can cause secondary contamination, significantly increasing the risk of infection and potentially leading to tumor cell implantation and metastasis, casting a huge shadow over subsequent treatment and seriously threatening the patient's health and life.

[0004] Therefore, this invention provides an abdominal drainage bottle for digestive oncology to solve the above problems. Utility Model Content

[0010] As a preferred technical solution of this application, a limiting groove is formed at the bottom of the inner arc surface of the plug, and the plug is connected to a drain tube through the cone angle of the outer arc surface. The inner arc surface of the groove cavity is provided with an internal thread.

[0015] (III) Beneficial Effects

[0016] 1. The connecting ring and the receiving bottom ring effectively prevent unstable phenomena such as shaking and displacement. The connecting rod between the connecting ring and the receiving bottom ring has excellent elasticity at its bottom end. When adapted to the body of the drainage bottle of different specifications and sizes, the elastic bottom end can adaptively press against the outer wall of the drainage bottle body, and together with the clamping ring and the receiving bottom ring, accurately position the drainage bottle body from multiple angles.

[0017] 2. Under compression, the cap and the drainage tube undergo elastic deformation in a localized area, thus tightly squeezing into the anti-detachment groove. In this way, on the one hand, the elastic deformation fills any tiny gaps that may exist between the components, achieving a sealing effect and effectively preventing leakage. On the other hand, the anti-detachment groove and the deformed drainage tube interlock with each other, forming a stable self-locking thrust structure, avoiding the risk of the drainage tube accidentally coming off during use.

[0018] 3. The drainage channel and inner drainage tube effectively divert the continuously accumulating liquid in the bottle, avoiding a series of potential problems such as poor drainage and backflow caused by excessive leakage, thus ensuring the efficient and safe progress of abdominal drainage.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides an abdominal drainage bottle for digestive oncology, such as... Figures 1 to 5 As shown, the device includes a drainage bottle body 1. A connecting ring 2 is fitted on the top of the outer arc surface of the drainage bottle body 1. A rubber block 201 is fitted on the inner arc surface of the connecting ring 2. An arc-shaped through groove is formed between the rubber block 201 and the connecting ring 2. A clamping ring 203 is fixedly installed on one end face of the rubber block 201. The outer arc surface of the clamping ring 203 is in contact with the outer arc surface of the drainage bottle body 1. A receiving bottom ring 3 is provided on the lower surface of the connecting ring 2. The middle part of the upper surface of the receiving bottom ring 3 is a hollow structure. An inclined angle 301 is provided in the hollow structure of the upper surface of the receiving bottom ring 3. The lower surface of the drainage bottle body 1 is placed on the inclined angle 301 surface. A connecting rod 4 is fixedly installed between the receiving bottom ring 3 and the connecting ring 2. The bottom end of the connecting rod 4 is an elastic structure. The top end of the connecting rod 4 extends through to the outside of the connecting ring 2 and is fixedly installed with a lifting ring 401.

[0028] In practical applications, the main body 1 of the drainage bottle is securely held by the clamping ring 203. The clamping force is derived from the elastic deformation of the rubber block 201, which plays a protective role during abdominal drainage. When an accidental collision occurs, the external impact force acts on the rubber block 201 first. Due to its good flexibility and buffering characteristics, it cleverly absorbs and disperses the collision energy, effectively preventing the rigid impact from being directly transmitted to the main body 1 of the drainage bottle. This ensures the structural integrity of the drainage bottle and the stable and continuous drainage operation, greatly reducing the risks such as drainage interruption and leakage caused by collision.

[0029] Furthermore, the rubber blocks 201 are spaced apart, forming gaps together with the clamping ring 203. These gaps provide ample space for adjusting the clamping force, allowing operators to easily and smoothly remove the main body 1 of the drainage bottle, regardless of its size or the subsequent handling, thus improving usability. To further optimize the buffering and deformation capabilities of the rubber blocks 201, a hollow structure is designed inside, which allows the rubber blocks 201 to achieve greater compression deformation under pressure.

[0030] Meanwhile, a support ring 3 is provided at the bottom of the drainage bottle body 1 for support. The upper surface of the support ring 3 is inclined at an angle 301 according to the bottom contour of the drainage bottle body 1. The two are adapted to each other, thereby effectively preventing unstable phenomena such as shaking and displacement. The connecting rod 4 connected between the connecting ring 2 and the support ring 3 has excellent elasticity at its bottom end. When adapted to drainage bottle bodies 1 of different specifications and sizes, the elastic bottom end can adaptively press against the outer wall of the drainage bottle body 1, and together with the clamping ring 203 and the support ring 3, accurately position the drainage bottle body 1 from multiple angles.

[0031] A bend 402 is provided at the connection between the connecting rod 4 and the lifting ring 401. A groove 101 is provided on the upper surface of the drainage bottle body 1. A plug 102 is provided in the middle of the upper surface of the groove 101. A cone angle 103 is provided on the outer arc surface of the plug 102. A limiting groove 104 is provided at the bottom of the inner arc surface of the plug 102. The drainage tube 5 is connected to the plug 102 through the cone angle 103 of the outer arc surface. An internal thread is provided on the inner arc surface of the groove 101. A compression cap 6 is connected to the groove 101 through the internal thread. An external thread is provided on the outer arc surface of the compression cap 6 and is adapted to the internal thread of the groove 101. The bottom of the compression cap 6 is a conical structure. A sealing rubber ring 7 is provided at the bottom of the compression cap 6. The lower surface of the sealing rubber ring 7 is attached to the bottom of the groove 101.

[0032] At the top of the drainage bottle body 1, the plug 102 is provided with a tapered angle 103, presenting a textured pattern of convex and concave sections. This not only increases the friction when in contact with other components but also facilitates subsequent tight fitting operations. The matching drainage outer tube 5 has elastic properties. During assembly, the drainage outer tube 5 is slowly squeezed in from the lower outer end of the plug 102, smoothly entering the groove cavity 101 due to its own elasticity. At this time, to ensure the sealing and stability of the connection, when the external thread of the clamping cap 6 is tightly pressed along the outer wall of the groove cavity 101, it will exert a strong force on the drainage outer tube 5. Under the large radial compression, due to the elasticity of the drainage tube 5, its local area undergoes elastic deformation, thus tightly squeezing into the anti-dislodgement groove. In this way, on the one hand, the elastic deformation fills any tiny gaps that may exist between the components, achieving a sealing effect and effectively preventing leakage. On the other hand, the anti-dislodgement groove and the deformed drainage tube 5 interlock with each other, forming a stable self-locking thrust structure, avoiding the risk of the drainage tube 5 accidentally dislodging during use, and comprehensively ensuring the reliability and stability of the abdominal drainage system during operation.

[0033] The inner arc surface of the plug 102 is connected to the inner drainage tube 8. One end of the inner drainage tube 8, which extends to the body of the drainage bottle 1, is attached to the surface of the connecting rod 4. The bottom end of the outer arc surface of the inner drainage tube 8 is connected to the drainage channel 9. A horizontal section 901 is provided in the middle of one side of the drainage channel 9. A vertical section 902 is provided at the top of the drainage channel 9 and extends to the outside of the body of the drainage bottle 1. One end of the vertical section 902 extends into the inner drainage tube 8.

[0034] In the actual operation of abdominal drainage, it is crucial to effectively prevent the drainage bottle body 1 from becoming overfilled. To this end, a limiting groove 104 is cleverly provided on the inner arc surface of the plug 102, which is connected to the drainage channel 9. When the liquid inside the drainage bottle body 1 continues to accumulate and the liquid level gradually rises, before it becomes overfilled, a hole is provided on the horizontal section 901 in the middle of the drainage channel 9, allowing the rising liquid to enter the drainage channel 9 through the hole. As the liquid level rises further, more and more liquid flows into the drainage channel 9. When the drainage channel 9 is partially filled, the liquid follows the guidance of gravity and pressure difference, rising along the vertical section 902 of the drainage channel 9, and finally smoothly enters the drainage inner tube 8. In this way, the continuously accumulating liquid in the bottle is diverted, effectively avoiding a series of potential problems caused by overfilling, such as poor drainage and backflow of exudate, and ensuring the efficient and safe progress of abdominal drainage.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
