[0002] A drainage bag is a medical device used to collect fluids, secretions, or waste from inside or outside the body. Drainage bags are designed to help wounds heal, reduce the risk of infection, or reduce swelling by draining accumulated fluid from the body. Drainage bags require an interface and a drainage tube for use.

[0003] Existing drainage bags are simply combined with drainage tubes via an interface. This means that the drainage bag needs to be replaced with a different type depending on the drainage tube connector, which is cumbersome. The drainage tube and the interface on the drainage bag must be completely compatible for it to be used, and multiple drainage tube connectors cannot be matched.

[0004] An innovative design was made based on the existing drainage bag. Utility Model Content

The existing drainage bags on the market are simply combined with drainage tubes through interfaces, which means that the drainage bag as a whole needs to be replaced with the corresponding type of drainage bag depending on the different drainage tube connectors. This is cumbersome and requires the drainage tube and the interface on the drainage bag to be completely matched before it can be used. It cannot match multiple drainage tube connectors.

[0024] 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.

[0025] Please see Figures 1 to 7 This utility model provides a technical solution: a multi-interface adjustable drainage bag, including a drainage bag body 1 and a combined connecting block 2. The combined connecting block 2 is fixedly installed in the center of the bottom end of the drainage bag body 1, and the combined connecting block 2 has an inner groove 3 inside. The top of the combined connecting block 2 has a liquid inlet hole 4, and the bottom of the combined connecting block 2 has a connecting hole 5. The front surface of the combined connecting block 2 has a combined hole 6, and the front surface of the combined connecting block 2 has a limiting protrusion 7. The bottom of the combined connecting block 2 is equipped with a first connecting pipe 15, a second connecting pipe 16, and a third connecting pipe 17, and the top ends of the first connecting pipe 15, the second connecting pipe 16, and the third connecting pipe 17 are connected to the connecting hole 5. A sealing shaft 8 is installed inside the inner groove 3.

[0026] The internal spaces of the liquid inlet hole 4 and the connecting hole 5 are interconnected with the internal space of the inner hole groove 3. The inner hole groove 3 is evenly distributed within the combined connecting block 2, which is beneficial for the subsequent assembly. Based on the distribution of the inner hole groove 3, the liquid inlet channels at different positions can be opened and closed.

[0027] A flow hole 9 is provided at the center of the sealing shaft 8, and a rotating shaft 10 is provided at the center of the front end of the sealing shaft 8. The rotating shaft 10 passes through the combined hole 6, and a sealing rubber ring 11 is sleeved on the outer side of the rotating shaft 10. An adjusting knob 12 is installed on the front end face of the rotating shaft 10, and a positioning block 13 and an anti-slip strip 14 are provided on the outer side of the curved surface of the adjusting knob 12. The axis lines of the flow holes 9 are aligned with each other, and the flow holes 9 are connected to the combined connecting block 2 by rotation through the sealing shaft 8 and the inner hole groove 3. The outer surface of the sealing shaft 8 is in contact with the inner wall of the combined connecting block 2 for sealing. The angle of the flow holes 9 can be adjusted by rotating the sealing shaft 8, so that the flow holes 9 are aligned with or misaligned with the liquid inlet hole 4 and the connecting hole 5. And according to the combination of the sealing shaft 8, liquid is prevented from entering the inner hole groove 3.

[0028] The rotating shaft 10 is connected to the sealing shaft 8 and the adjusting knob 12 by embedding and fixing. The rotating shaft 10 is connected to the combined connecting block 2 through the combined hole 6 by rotation. The sealing rubber ring 11 on the rotating shaft 10 is connected to the inner wall of the combined connecting block 2 by compression. The rotating shaft 10 can rotate through the combined hole 6. At the same time, the rotating shaft 10 maintains the sealing during the rotation process according to the sealing rubber ring 11, improves the friction, and avoids easy loosening.

[0029] The adjusting knob 12, the positioning block 13, and the anti-slip strip 14 are integrated into a single structure. The anti-slip strip 14 is evenly distributed on the adjusting knob 12. The positioning block 13 and the limiting protrusion 7 are connected by a fitted connection. The limiting protrusion 7 is evenly distributed on the combined connecting block 2. The adjusting knob 12 can be manually rotated by the anti-slip strip 14 on the adjusting knob 12. The adjusting knob 12 drives the positioning block 13 to rotate. The rotation angle position can be limited by the positioning block 13, which is conducive to the precise alignment and precise misalignment adjustment of the flow hole 9.

[0030] The first connector 15, the second connector 16, and the third connector 17 are connected to the combined connecting block 2 by means of embedded fixing through the connecting hole 5, and the axis of the connecting hole 5 is aligned with the axis of the liquid inlet hole 4. Different drainage tube connectors can be installed according to the type of the first connector 15, the second connector 16, and the third connector 17, so as to flexibly adjust according to the needs.

[0031] Working principle: According to Figures 1 to 7When it is necessary to combine the external drainage tube with the drainage bag body 1, the type of connector on the drainage tube can be matched with the first connecting pipe 15, the second connecting pipe 16, and the third connecting pipe 17 installed on the combination connecting block 2. After the matching is completed, the adjustment knob 12 above it can be turned manually. The anti-slip strip 14 set on the adjustment knob 12 increases the friction of manual operation and avoids slippage. This causes the adjustment knob 12 to drive the positioning block 13 to rotate. The adjustment knob 12 drives the rotating shaft 10 to rotate on the combination connecting block 2 through the combination hole 6. At the same time, the rotating shaft 10 drives the sealing rubber ring 11 to rotate, increasing the friction. The rotating shaft 10 drives the sealing shaft body. 8. The sealing rotation within the combined connecting block 2 via the inner groove 3 causes the adjusting knob 12 to rotate the sealing shaft 8 by 90°. The adjusting knob 12 then causes the positioning block 13 to engage with another limiting protrusion 7, allowing for precise determination of the rotation angle. This aligns the sealing shaft 8 with the flow hole 9, the inlet hole 4, and the connecting hole 5, completing the opening process. The connector on the drain tube can then be inserted and combined using one of the corresponding matched first connecting pipe 15, second connecting pipe 16, or third connecting pipe 17, while the other two remain sealed. This is the entire working process of the device. Any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
