For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0030] Figure 1 The structure of the three-way pipe connector according to the preferred embodiment of the present application is schematically shown.

[0031] As Figure 1 shown, the three-way pipe connector according to the preferred embodiment of the present application comprises a three-way joint 10, wherein a universal interface 20 is arranged at a first opening of the three-way joint 10, a spiral interface 30 is arranged at a second opening of the three-way joint 10, a third opening of the three-way joint 10 is connected to an extension pipe 40, and a funnel-shaped pipe 60 is connected to one end of the extension pipe 40, wherein the diameter of the funnel-shaped pipe 60 gradually increases in the direction away from the extension pipe 40.

[0032] For example, the funnel-shaped pipe 60 can be advantageously used to connect pipelines such as nutrient tubes.

[0033] Preferably, the funnel-shaped tube 60 is provided with a cover 70 connected to the funnel-shaped tube 60 for closing the opening of the funnel-shaped tube 60.

[0034] Preferably, such as Figure 1 As shown, the tee connector according to a preferred embodiment of the present invention further includes a switch 50 for controlling the opening and closing of each passage of the tee connector 10.

[0035] Preferably, the extension tube 40 and the funnel-shaped tube 60 are connected by threads.

[0036] Preferably, the funnel-shaped tube 60 is made of a flexible material and is elastic.

[0037] Preferably, the spiral interface 30 and the universal interface 20 are adjacent to each other, and one of the spiral interface 30 and the universal interface 20 is opposite to the extension tube 40.

[0038] Preferably, the spiral interface 30 and the universal interface 20 can be connected to each other to form a closed port.

[0039] Figure 2 A side view of the funnel-shaped tube of a tee connector according to a preferred embodiment of the present invention is shown schematically. Figure 3 A schematic top view of the funnel-shaped tube and cap of a tee connector according to a preferred embodiment of the present invention is shown.

[0040] Preferably, such as Figure 2 and Figure 3 As shown, the funnel-shaped tube 60 includes a stepped portion 61 formed at the end (outer end, i.e., the end with the largest diameter) of the funnel-shaped tube body, and an opening 62 is formed within the stepped portion 61; and the cover 70 includes a central protrusion 71 and a peripheral protrusion 72, wherein the outer circumference of the central protrusion 71 matches the opening 62 so as to completely close the opening 62 when inserted, and the inner circumference of the peripheral protrusion 72 matches the stepped portion 61 so as to completely surround the stepped portion 61 when the central protrusion 71 is inserted into the opening 62. Thus, the cover 70 can completely close the opening of the funnel-shaped tube 60.

[0041] also, Figure 4 A top view schematically shown is of the cover of a tee connector according to a further preferred embodiment of the present invention.

[0042] like Figure 4 As shown, the cover of the three-way pipe connector according to a further preferred embodiment of the present invention includes: an opening 73 formed in the central region of the cover body and an insert 74, wherein the insert 74 closes the opening 73 when inserted into it, and the insert 74 is connected to the cover body by a flexible connector 75. Figure 4An example is shown where the central region of the cover body corresponds to the center of the central protrusion 71. However, the cover body may also exclude the central protrusion 71, and instead the opening 73 may be formed directly on the flat surface.

[0043] It can be seen that the opening 62 of the funnel-shaped tube 60 has a first fitting size, and the opening 73 of the cover body has a second fitting size, so that it can be matched with a variety of interfaces.

[0044] More preferably, for example, the central region of the insert 74 may also have a secondary opening, and the insert 74 further includes a secondary insert that can close the secondary opening when it is inserted. In this way, the secondary opening can form a third fitting size, further achieving the goal of matching multiple interfaces. Moreover, by analogy, multi-level openings can be formed, thereby creating more fitting sizes and specifications.

[0045] For example, a tee connector according to a preferred embodiment of the present invention is used in a drainage device.

[0046] The tee connector according to the preferred embodiment of this utility model can be matched between most clinical tubing and can be connected to other devices, and has at least the following technical effects:

[0047] 1. It can be compatible with multiple interfaces, improving ease of use.

[0048] 2. Reduced the risk of errors caused by interface incompatibility.

[0049] 3. It further improves work efficiency, especially saving time in emergencies.

[0050] Furthermore, it should be noted that, unless otherwise specified, the terms "first," "second," "third," etc., in the specification are used only to distinguish the various components, elements, and steps in the specification, and are not used to indicate the logical or sequential relationships between the various components, elements, and steps.

[0051] It is understood that although the present invention has been disclosed above with reference to preferred embodiments, these embodiments are not intended to limit the present invention. For any person skilled in the art, many possible variations and modifications can be made to the present invention without departing from the scope of the present invention, or equivalent embodiments can be modified based on the disclosed technical content. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
