All drainage tubes need to be connected to the inlet tube of a tissue fluid collection bag via a connector to drain the tissue fluid into the bag. Currently, there is no suitable connector, and each time a drainage tube is connected to the tissue fluid collection bag, medical staff have to cut multiple sections of drainage tubes of different diameters to make their own connectors, then wrap them with tape to connect them, which is very inconvenient.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments.

[0018] like Figure 1 As shown, a connector suitable for drainage tubes of different diameters includes: a connector body 1, the connector body 1 being hollow inside, and at least two connecting pipe assemblies 20 being provided on the connector body 1, each connecting pipe assembly 20 being connected to the interior of the connector body 1.

[0019] In this embodiment, the connector body 1 is Y-shaped. The Y-shaped structure facilitates connection and timely drainage of tissue fluid. In this embodiment, the Y-shaped connector body 1 is equipped with three connecting pipe assemblies 20, located at the three ports of the Y. The two connecting pipe assemblies 20 at the upper end are used to connect to the drainage tube, and the connecting pipe assembly 20 at the lower end is used to connect to the inlet tube of the tissue fluid collection bag, thus facilitating rapid drainage of the tissue fluid after inflow.

[0020] See Figure 2 , Figure 3 , Figure 4 As shown, each pipe assembly 20 includes a pipe 2 fixedly connected to the connector body 1. The pipe 2, from the inside out, includes a body segment 21 and at least two spaced-apart connecting segments. In this embodiment, three connecting segments are spaced-apart, and from the inside out, they are the first connecting segment 22, the second connecting segment 23, and the third connecting segment 24. The body segment 21, the first connecting segment 22, the second connecting segment 23, and the third connecting segment 24 are all straight pipe segments. The diameters of the body segment 21, the first connecting segment 22, the second connecting segment 23, and the third connecting segment 24 decrease sequentially.

[0021] A tapered pipe segment connects the main body segment 21 to adjacent connecting segments, and between each pair of adjacent connecting segments. The diameter of each tapered pipe segment gradually increases from its outer connecting segment towards its inner connecting segment or towards its inner main body segment. Specifically: a first tapered pipe segment 25 is provided between the main body segment 21 and the first connecting segment 22, and the diameter of the first tapered pipe segment 25 gradually increases from the first connecting segment 22 towards the main body segment 21; a second tapered pipe segment 26 is provided between the first connecting segment 22 and the second connecting segment 23, and the diameter of the second tapered pipe segment 26 gradually increases from the second connecting segment 23 towards the first connecting segment 22; a third tapered pipe segment 27 is provided between the second connecting segment 23 and the third connecting segment 24, and the diameter of the third tapered pipe segment 27 gradually increases from the third connecting segment 24 towards the second connecting segment 23.

[0022] The diameter of the inlet tube of the drainage tube or tissue fluid collection bag is adapted to one of the first connecting section 22, the second connecting section 23, and the third connecting section 24. The inlet tube of the drainage tube or tissue fluid collection bag can be tightly fitted onto the adapted connecting section and the tapered tube section at the inner end of the connecting section, or it can pass through the connecting section and the tapered tube section at the outer end of the adapted connecting section and then be fitted onto the adapted connecting section and the tapered tube section at the inner end of the connecting section.

[0023] Each tapered pipe section has a corresponding tapered locking sleeve on its outer wall. Each locking sleeve has a straight external thread connection section and an internal thread connection section at both ends. The outer wall of the internal thread connection section of each locking sleeve is provided with an anti-slip surface 7 for easy operation.

[0024] Specifically, a first locking sleeve 4 is provided outside the first tapered tube section 25, and a first external threaded connection section 41 and a first internal threaded connection section 42 are respectively provided at the small diameter end and the large diameter end of the first locking sleeve 4.

[0025] A second locking sleeve 5 is provided outside the second tapered tube section 26. The small diameter end and the large diameter end of the second locking sleeve 5 are respectively provided with a second external threaded connection section 51 and a second internal threaded connection section 52. A second locking step 521 for limiting is provided on the inner wall of the second internal threaded connection section 52.

[0026] A third locking sleeve 6 is provided outside the third tapered tube section 27. The small diameter end and the large diameter end of the third locking sleeve 6 are respectively provided with a third external thread connection section 61 and a third internal thread connection section 62. A third locking step 621 for limiting is provided on the inner wall of the third internal thread connection section 62.

[0027] The outer wall of the main body section 21 near the first tapered tube section 25 is provided with threads.

[0028] In each pair of adjacent locking sleeves, the inner threaded connection section of the outer locking sleeve can be threadedly and sealed to the outer threaded connection section of the innermost locking sleeve, and the inner threaded connection section of the innermost locking sleeve can be threadedly and sealed to the body section 21. The threaded sealing between the locking sleeve and the corresponding outer threaded connection section can securely fasten and fix the inlet tube of the drainage tube or tissue fluid collection bag located inside it.

[0029] Specifically, the third internal threaded connecting section 62 of the third locking sleeve 6 can be threadedly fixed and sealed with the second external threaded connecting section 51 of the second locking sleeve 5, thereby clamping and fixing the drainage tube or the input tube of the tissue fluid collection bag fitted on the third connecting section 24 and the third tapered tube section 27.

[0030] The second internal threaded connecting section 52 of the second locking sleeve 5 can be threadedly fixed and sealed with the first external threaded connecting section 41 of the first locking sleeve 4, thereby clamping and fixing the inlet tube of the drainage tube or tissue fluid collection bag that can be fitted onto the second connecting section 23 and the second tapered tube section 26.

[0031] The first internal threaded connecting section 41 of the first locking sleeve 4 can be threadedly and sealed to the body section 21, thereby clamping and fixing the inlet tube of the drainage tube or tissue fluid collection bag that can be fitted on the first connecting section 22 and the first tapered tube section 25.

[0032] The connector suitable for drainage pipes of different diameters described in this embodiment also includes at least one cap 3 with internal threads. The cap 3 can be threaded onto the external threaded connection section with the smallest diameter, thereby sealing the corresponding pipe assembly. That is, the cap 3 can be threaded onto the third external threaded connection section 61.

[0033] The working principle of the connector with the above structure suitable for drainage pipes of different diameters is described in detail below.

[0034] Each connector assembly 20 has three different diameter connecting sections: a first connecting section 22, a second connecting section 23, and a third connecting section 24, with the diameters decreasing sequentially from 22 to 23. These three connecting sections provide three different diameter connection possibilities, thus accommodating the diameters of drainage tubes or inlet tubes of tissue fluid collection bags of three different diameters.

[0035] like Figure 2 As shown, when the diameter of the first drainage tube 8 is compatible with the third connecting section 24, the third locking sleeve 6 is first unscrewed from the second external threaded connecting section 51 of the second locking sleeve 5. Then, the first drainage tube 8 is passed through the third locking sleeve 6 and fitted onto the third connecting section 24. Since the drainage tube is usually made of plastic and has a certain degree of deformation, the drainage tube is further squeezed to allow it to pass through the third connecting section 24 and be inserted into the outer wall of the third tapered tube section 27. Then, the third internal threaded connecting section 62 of the third locking sleeve 6 is threadedly fixed to the second external threaded connecting section 51. Since the third locking sleeve 6 is tapered, as the third locking sleeve 6 moves toward the second external threaded connecting section 51, its small-diameter end will press against the first drainage tube 8 inside, thereby fixing and sealing the first drainage tube to the connecting pipe assembly 20.

[0036] like Figure 3 As shown, when the diameter of the second drainage tube 9 is compatible with the second connecting section 23, the third locking sleeve 6 is first unscrewed from the second external threaded connecting section 51 of the second locking sleeve 5, and the second locking sleeve 5 is unscrewed from the first external threaded connecting section 41 of the first locking sleeve 4. Then, the second drainage tube 9 is passed through the second locking sleeve 5 and fitted onto the second connecting section 23. Similarly, the second drainage tube 9 is further squeezed to allow it to pass through the second connecting section 23 and be inserted into the outer wall of the second tapered tube section 26. Then, the second internal threaded connecting section 52 of the second locking sleeve 5 is threaded and sealed to the first external threaded connecting section 41. Since the second locking sleeve 5 is tapered, as the second locking sleeve 5 moves toward the first external threaded connecting section 41, its small-diameter end will press against the second drainage tube 9 inside, thereby fixing and sealing the second drainage tube 9 with the connecting pipe assembly 20.

[0037] like Figure 4As shown, when the diameter of the third drainage tube 10 is compatible with the first connecting section 22, the third locking sleeve 6 is first unscrewed from the second external threaded connecting section 51 of the second locking sleeve 5, then the second locking sleeve 5 is unscrewed from the first external threaded connecting section 41 of the first locking sleeve 4, and then the first locking sleeve 4 is unscrewed from the body section 21. Next, the third drainage tube 10 is passed through the first locking sleeve 4 and fitted onto the first connecting section 22. Similarly, the third drainage tube 10 is further compressed so that it passes through the first connecting section 22 and is inserted into the outer wall of the first tapered tube section 25. Then, the first internal threaded connecting section 42 of the first locking sleeve 4 is threaded and fixedly connected to the body section 21. Since the first locking sleeve 4 is tapered, as the first locking sleeve 4 moves towards the body section 21, its smaller diameter end presses against the third drainage tube 10 inside, thereby fixing and sealing the third drainage tube 10 to the connecting pipe assembly 20.

[0038] Similarly, the connection between the inlet tube and the connector on the tissue fluid collection bag can be made by referring to the above process and selecting a suitable connection section according to the diameter of the inlet tube.

[0039] If there are excess pipe fittings 20 on the connector body 1, the cap 3 is connected to the smallest diameter external threaded connection section to seal the corresponding pipe fitting. That is, the cap 3 can be threaded onto the third connection section 24 to seal the corresponding pipe fitting.

[0040] As can be seen from the above, this application provides a connector suitable for drainage tubes of different diameters. It has a simple structure, is very convenient to use, and has multiple connector assemblies 20, allowing it to connect to multiple drainage tubes. Since each connector assembly 20 is equipped with multiple connection sections of different diameters, it can be used to connect drainage tubes or inlet tubes of tissue fluid collection bags of different diameters, which greatly facilitates the work of medical personnel in managing patient wound drainage.
