Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a conversion device that can convert a conventional drainage tube into a flushing drainage tube. Background Technology

[0002] For patients requiring postoperative drainage tubes, irrigation drainage is sometimes necessary to aid recovery, depending on the characteristics of the drainage fluid. In clinical practice, when encountering patients who require irrigation drainage but did not have an intraoperative irrigation drainage tube, medical staff often need to modify the existing drainage tube to enable irrigation drainage. However, this requires a certain level of professional skill from the medical staff performing the modification, and even if the modification is successful, leakage often occurs, frequently necessitating repeated modification procedures. This not only consumes a significant amount of time and increases the workload of medical staff but also causes pain for patients, resulting in a poor medical experience.

[0003] In the existing technology, there are some patents designed to modify ordinary drainage tubes into drainage tubes with flushing and drainage functions to address the above situations. However, their functions are limited and cannot meet the diverse clinical needs. For example, patent CN209154855U discloses a dual-lumen sleeve connector device for sustainable flushing and drainage, which can modify an indwelling ordinary drainage tube into a sustainable flushing and drainage tube. However, this device is a one-piece molded structure, which cannot flexibly adjust the length and type of the indwelling flushing tube. Another example is patent CN205796111U, which discloses a dual-lumen sleeve flushing and drainage device. This device, by artificially creating holes in the side wall of the tubing, is prone to leakage of the drainage fluid; moreover, it has specific requirements for the material and type of the flushing tube, making it inflexible and inconvenient in practical applications.

[0004] Therefore, there is an urgent need for a device that allows for the conversion of drainage tubes into flushing drainage tubes in clinical applications, making the process more convenient and flexible. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device for converting a drainage tube and a flushing drainage tube, in view of the problems existing in the background art.

[0006] Therefore, the present invention provides the following technical solution: A device for converting a drainage tube to a flushing drainage tube includes a drainage tube connector, a main structure for connecting a drainage bag connector, a flushing tube insertion interface, and a screw cap. The drainage tube connector is configured to be tightly connected to the drainage tube and not easily slipped off. The drainage tube connector is connected to both the drainage bag connector and the flushing tube insertion interface through the main structure.

[0007] Preferably, the drainage tube connector is provided with anti-slip texture to further enhance the stability of the connection with the drainage tube and prevent slippage.

[0008] Preferably, the main structure, the flushing tube insertion interface, and the screw cap are made of transparent material.

[0009] Preferably, the main structure can be tightly connected to the connector of a clinically standard drainage bag, making it less prone to slippage.

[0010] Preferably, the spiral cap has a threaded structure and a soft pad inside the spiral cap, the soft pad having a circular opening.

[0011] Preferably, the pad is soft and easily deformed; tightening the screw cap can compress the pad, and the deformed pad will seal with the flushing pipe.

[0012] Preferably, the spiral cap of the flushing tube insertion interface can be tightened to secure the flushing tube, and the length of the flushing tube can be adjusted as needed after the spiral cap is loosened.

[0013] Preferably, in the described drainage tube and flushing drainage tube conversion device, the spiral cap has a circular opening, and the diameter of the circular opening of the spiral cap is larger than the diameter of the circular opening of the cushion.

[0014] Preferably, the diameter of the circular opening of the pad is smaller than the inner diameter of the flushing tube insertion interface, the inner diameter of the main structure, and the inner diameter of the drainage tube connector.

[0015] Preferably, the padding is not easily slipped off from the circular opening of the screw cap.

[0016] The beneficial effects of this invention are: This invention comprises a drainage tube connector, a main structure connecting to a drainage bag connector, a flushing tube insertion interface, and a screw cap. The drainage tube connector connects to the drainage tube, and the drainage bag connector connects to the drainage bag, ensuring unobstructed drainage. The flushing tube insertion interface and screw cap allow for flexible selection of tubing with a diameter smaller than the circular opening diameter of the soft pad (such as infusion sets, disposable connectors, etc.) as the flushing tube. Tightening the screw cap causes the soft pad to deform under pressure, sealing against the flushing tube, effectively preventing leakage and securing the flushing tube. The screw cap allows for flexible adjustment of the flushing tube insertion depth based on the internal depth of the drainage tube, and drainage fluid samples can be collected through the flushing tube insertion interface and the inserted tubing. This invention is simple to operate and highly practical. Attached Figure Description

[0021] To enable those skilled in the art to better understand and implement the technical solutions of this invention, the invention will be described in detail, clearly, and completely below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Furthermore, based on the embodiments of this invention, any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art to all other embodiments obtained without creative effort should be included within the protection scope of this invention patent.

[0022] The following is a detailed description of the specific implementation of the drainage tube and flushing drainage tube conversion device, with reference to the accompanying drawings.

[0023] This drainage tube and flushing drainage tube conversion device includes a drainage tube connector 1, which can be connected to the drainage tube 11. The connector surface is textured to ensure a tight connection between the drainage tube connector and the drainage tube, preventing slippage. The drainage tube connector 1 is interconnected with the flushing tube insertion interface 3 and the drainage bag interface 8 via the main structure 2. The drainage bag interface 8 is compatible with a commercially available drainage bag connector 12 and is used to drain drainage fluid or flushing fluid into the drainage bag.

[0024] The flushing tube insertion interface 3 of this drainage tube and flushing drainage tube conversion device is connected to the screw cap 4 via a threaded structure. As shown in the front view 5 of the screw cap, the screw cap has a circular opening 9. Inside the screw cap is a soft pad 6, which has a circular opening 10, and the diameter of the circular opening 10 of the soft pad is smaller than the diameter of the circular opening 9 of the screw cap. The diameter of the drainage tube connector opening 7 is larger than the diameter of the circular opening 10 of the soft pad, to ensure sufficient space between the flushing tube and the drainage tube connector 1, ensuring that the drainage fluid can smoothly pass through the drainage tube connector opening 7 and the drainage bag interface 8 into the drainage bag.

[0025] The screw cap of this drainage tube and flushing drainage tube conversion device has a built-in soft pad 6. This soft pad is soft and easily deforms under pressure. The flushing tube can be smoothly inserted into the drainage tube by passing through the circular opening 9 of the screw cap, the circular opening 10 of the soft pad, the flushing tube insertion interface 3, and the drainage tube connector opening 7 in sequence. The insertion length of the flushing tube can be adjusted according to the insertion length of the drainage tube. When the screw cap 4 is tightened, the screw cap 4 can press the soft pad structure 6 built into the screw cap against the flushing tube insertion interface 3. The soft pad structure 6 built into the screw cap deforms under pressure, and the diameter of the circular opening 10 of the soft pad decreases, thus making it fit tightly against the flushing tube, which can not only prevent leakage, but also fix the flushing tube.

[0026] This drainage tube and flushing drainage tube conversion device allows for flexible selection of tubing with a diameter smaller than the diameter of the soft pad's circular opening (such as infusion sets, disposable connectors, etc.) as flushing tubes via the flushing tube insertion interface; it also allows for operations such as collecting drainage fluid samples through the flushing tube insertion interface and the inserted tubing.

[0027] Although preferred embodiments of the present invention have been described in detail in the specification, those skilled in the art, once they understand the basic inventive concept, may make other changes and modifications to these embodiments or combinations of embodiments without inventive effort. Therefore, the scope of protection of this patent should be determined according to the scope interpreted and covered by the claims, and should not be limited to the detailed description in the specification and embodiments. Furthermore, including the preferred embodiments, the content described in this patent covers all changes and modifications falling within the scope of protection of this patent.
