Abstract
Description
Valve device for medical bags Technical Field
[0001] This invention relates to a valve, and more particularly to a valve device for a medical bag. Background Technology
[0002] For example, Chinese utility model patent CN219700643U discloses a urine bag for easy urine collection, which includes a connector at the upper end of the urine bag, with a connector head inside, and a drainage tube fixedly connected to the upper end of the connector head. The lower end of the urine bag has a drain tube, and a cross valve is installed in the middle of the drain tube. After urine collection is complete, squeezing one side of the cross valve allows the urine to be discharged from the drain tube. Technical issues
[0003] Because the drain pipe is designed to hang downwards and has a certain length, it is easy for it to come into contact with unclean external objects or touch the ground during use, which may lead to infection. Technical solutions
[0004] To address the aforementioned issues, this invention provides a valve device for a medical bag. When in the closed position, the drain pipe of the switching component is raised relative to the guide pipe of the connecting component, reducing the portion of the drain pipe exposed below the medical bag and preventing the drain pipe from accidentally touching the ground or foreign objects, thus effectively preventing infection problems.
[0005] To achieve the aforementioned objectives, the present invention provides a valve device for a medical bag in one embodiment. The valve device is disposed at the bottom end of a medical bag and includes a connector and a switching member. The connector has a first mounting portion and a guide tube extending from the first mounting portion, the guide tube being connected to the medical bag. The switching member has a second mounting portion and a drain tube extending from the second mounting portion, the second mounting portion being disposed on the first mounting portion, allowing the switching member to rotate relative to the connector between an open position and a closed position. When in the closed position, the guide tube and the drain tube are not connected, and the drain tube is in an upward state relative to the guide tube. When in the open position, the guide tube and the drain tube are connected, and the drain tube is in a downward and parallel state relative to the guide tube.
[0006] The first mounting part has an assembly groove with a guide hole that connects to the guide pipe; the second mounting part has a valve plate extending through the assembly groove. When closed, the valve plate is blocked by the guide hole, and the guide pipe and the drain pipe are not connected; when open, the valve plate is offset from the guide hole, and the guide pipe and the drain pipe are connected.
[0007] In the closed position, the drain pipe and the guide pipe have an angle of less than 90 degrees.
[0008] The assembly slot is equipped with a limiting block to limit the rotation angle of the valve plate.
[0009] The switching component has a cylinder connected to the drain pipe, and a valve plate extends from the periphery of the cylinder. One side of the valve plate has an opening, which is connected to the guide hole when in the open position.
[0010] The valve plate is arc-shaped and has a first side and a second side. The limiting block protrudes from the bottom of the assembly groove. When the valve is closed, the first side blocks the limiting block. When the valve is open, the second side blocks the limiting block.
[0011] The assembly groove is equipped with a limiting ring, and there is an annular groove between the limiting ring and the inner wall of the assembly groove, which allows the valve plate to be rotated.
[0012] The assembly slot is provided with a first positioning part, and the valve plate part has a second positioning part that is matched with the first positioning part so that the valve plate part can be positioned in the closed position or the open position.
[0013] The first positioning part consists of two protrusions at the bottom of the assembly groove, which are distributed along the inner periphery of the assembly groove. The second positioning part consists of a concave hole at the bottom of the valve plate part. In the closed position, the concave hole is connected and positioned with one of the protrusions. In the open position, the concave hole is connected and positioned with the other protrusion.
[0014] The first mounting part has an outer protruding ring, and the assembly groove is located inside the outer protruding ring; the switching part has a connecting groove, and the connecting groove has a cylinder connected to the drain pipe. The valve plate extends from the periphery of the cylinder, the outer protruding ring is connected to the connecting groove, and the second mounting part cannot detach from the first mounting part along the axial direction of the assembly groove.
[0015] Among them, a stop flange is provided on each side of the inner edge of the groove, and the stop flange abuts against the bottom of the outer convex ring.
[0016] The outer convex ring has an inner sleeve ring spaced apart on its inner side; the outer side of the cylinder has a spacer ring that divides the connecting groove into a first groove and a second groove. The outer convex ring is located in the first groove, and the inner sleeve ring is located in the second groove, so that the outer convex ring and the inner sleeve ring clamp the spacer ring.
[0017] The medical bag has a limiting part at the bottom, which has a limiting groove and a connected open end. When in the closed position, the end edge of the drain tube moves from the open end into and is limited in the limiting groove.
[0018] Therefore, the present invention employs a switching mechanism that rotates relative to the connecting mechanism so that when the switching mechanism is rotated to the closed position, the guide tube and the drain tube are not connected, and the drain tube of the switching mechanism is in an upward position relative to the guide tube of the connecting mechanism. This reduces the portion of the drain tube exposed below the medical bag, preventing the drain tube from accidentally touching the ground or foreign objects, and effectively preventing infection problems.

[0060] To facilitate the explanation of the central ideas expressed in the foregoing description of the invention, specific embodiments are now described. Furthermore, to better explain the principles of the invention, specific language will be used to describe these examples. However, it should be understood that this does not imply a limitation on the scope of the invention.
[0061] Those skilled in the art may conceive of and make various modifications and further improvements, including the technical features described herein and any other application of the principles of the invention. All such modifications and applications should be considered within the scope of this invention.
[0062] Please refer to Figures 1 to 9. In this embodiment of the invention, a valve device 100 is disposed at the bottom end of a medical bag 200, which may be a urine bag. The valve device 100 includes a connector 10 and a switching component 20.
[0063] The connector 10 has a first mounting portion 11 and a guide tube 12 extending from the first mounting portion 11. The guide tube 12 is connected to the bottom end of the medical bag 200. The first mounting portion 11 has an assembly groove 111, and the guide tube 12 is perpendicular to the axis of the assembly groove 111, as shown in Figure 3.
[0064] The switching member 20 has a second mounting portion 21 and a drain pipe 22 extending from the second mounting portion 21. The second mounting portion 21 is located on one side of the first mounting portion 11, allowing the switching member 20 to rotate relative to the connecting member 10 between an open position and a closed position. Referring to Figures 7 and 9, when in the closed position, the guide pipe 12 and the drain pipe 22 are not connected, and the drain pipe 22 is in an upward state relative to the guide pipe 12. Referring to Figures 1 and 6, when in the open position, the guide pipe 12 and the drain pipe 22 are connected, and the drain pipe 22 is in a downward and parallel state relative to the guide pipe 12.
[0065] Therefore, in the closed position, because the drain pipe 22 is in an upward position relative to the guide pipe 12, the drain pipe 22 will not accidentally touch the ground or foreign objects when the medical bag 200 is in use, thus avoiding infection problems. When in the open position, the drain pipe 22 is in a downward and parallel position relative to the guide pipe 12, and the guide pipe 12 is connected to the drain pipe 22 to drain the liquid in the medical bag 200.
[0066] As shown in Figures 2 and 3, in this embodiment of the invention, the assembly groove 111 of the first mounting part 11 has a guide hole 112 communicating with the guide pipe 12. The second mounting part 21 has a valve plate part 23 extending through the assembly groove 111. In the closed position, the valve plate part 23 stops at the guide hole 112, and the guide pipe 12 is not communicating with the drain pipe 22. In the open position, the valve plate part 23 is misaligned with the guide hole 112, and the guide pipe 12 is communicating with the drain pipe 22.
[0067] In an embodiment of the present invention, as shown in FIG7, in the closed position, the drain pipe 22 and the guide pipe 12 have an included angle θ, which is less than 90 degrees.
[0068] Continuing with Figures 2 and 3, in this embodiment of the invention, the assembly groove 111 is a circular groove. A limiting block 13 is provided within the assembly groove 111, protruding from the bottom of the assembly groove 111. The switching member 20 contains a cylinder 24, which is connected to the drain pipe 22 via a through hole 241. A valve plate portion 23 extends from the periphery of the cylinder 24, and one side of the valve plate portion 23 has an opening 231. In the open position, the opening 231 connects to the guide hole 112. Furthermore, the assembly groove 111 is provided with a limiting ring 111a, and an annular groove 111b is formed between the limiting ring 111a and the inner wall of the assembly groove 111.
[0069] The valve plate portion 23 is arc-shaped and has a first side 232 and a second side 233. As shown in FIG8, in the closed position, the first side 232 is blocked by the limiting block 13; as shown in FIG5, in the open position, the second side 233 is blocked by the limiting block 13. Therefore, the limiting block 13 can limit the rotation angle of the valve plate portion 23, ensuring that the valve plate portion 23 is in the open or closed position. The annular groove 111b in the assembly groove 111 allows the valve plate portion 23 to be rotated, so that the valve plate portion 23 is kept within a predetermined path range for rotation.
[0070] Furthermore, continuing with Figures 2 and 3, in this embodiment of the invention, the assembly groove 111 is provided with a first positioning part 14, and the valve plate part 23 has a second positioning part 25 that cooperates with the first positioning part 14, so that the valve plate part 23 can be positioned in a closed position or an open position. The first positioning part 14 consists of two protrusions located at the bottom of the assembly groove 111, distributed along the inner periphery of the assembly groove 111. The second positioning part 25 consists of a recessed hole located at the bottom of the valve plate part 23. In the closed position, the recessed hole is engaged with one of the protrusions for positioning; in the open position, the recessed hole is engaged with the other protrusion for positioning. In other embodiments, the first positioning part 14 may also be a recessed hole, and the second positioning part 25 may consist of two protrusions.
[0071] Please refer to Figures 2 to 4. In this embodiment of the invention, the first mounting part 11 has an outer protruding ring 113, and an inner sleeve ring 114 is provided at intervals on the inner side of the outer protruding ring 113. The height of the inner sleeve ring 114 is lower than the height of the outer protruding ring 113, and the assembly groove 111 is provided on the inner side of the inner sleeve ring 114.
[0072] The switching component 20 has a mating groove 26 on one side, and a cylinder 24 is disposed in the mating groove 26. A spacer ring 27 is provided on the outer side of the cylinder 24 to divide the mating groove 26 into a first groove 261 and a second groove 262. In addition, a stop flange 263 is provided on both sides of the inner edge of the mating groove 26. The two stop flanges 263 abut against the bottom of the outer convex ring 113, so that the outer convex ring 113 is engaged with the mating groove 26, and the second mounting part 21 cannot be disengaged from the first mounting part 11 along the axial direction of the assembly groove 111. During assembly, the outer convex ring 113 is disposed in the first groove 261, and the inner sleeve ring 114 is disposed in the second groove 262, so that the outer convex ring 113 and the inner sleeve ring 114 clamp the spacer ring 27, thereby making the switching component 20 stably assembled with the connecting component 10.
[0073] As shown in Figures 6 and 9, in this embodiment of the invention, the bottom end of the medical bag 200 has a limiting part 201. The limiting part 201 has a limiting groove 202 and a connected open end 203. When in the closed position, the end edge (free end) of the drain tube 22 moves from the open end 203 into and is limited in the limiting groove 202 so as to keep the drain tube 22 in position.
[0074] Therefore, the present invention employs a switching element 20 that is rotatably mounted on the connector 10. When the switching element 20 is rotated relative to the connector 10 to the closed position, the guide tube 12 and the drain tube 22 are not connected, and the drain tube 22 of the switching element 20 is raised relative to the guide tube 12 of the connector 10, so as to reduce the portion of the drain tube 22 exposed below the medical bag 200, avoid the drain tube 22 from accidentally touching the ground or foreign objects, and effectively prevent infection problems from occurring.
[0075] Although the present invention has been described with reference to a preferred embodiment, those skilled in the art can make various modifications without departing from the spirit and scope of the invention. The embodiments described above are merely illustrative and not intended to limit the scope of the invention.
