[0028] See also Figures 1 to 8 As shown, the present invention provides a multifunctional medical drainage bag 100, comprising a main bag 1 and a side bag 2, wherein the connection between the main bag 1 and the side bag 2 is formed by a hot pressing process; a liquid inlet pipe 3 is provided at the upper end of the main bag 1, and a liquid outlet pipe 4 is provided at the lower end; a multi-way connecting assembly 5 is installed at the liquid inlet pipe 3; the side bag 2 is arranged at the lower end of the main bag 1 and located on both sides of the liquid outlet pipe 4, the main bag 1 and the side bag 2 are connected through a connecting pipe 6, the bottom end of the connecting pipe 6 is movably connected with a sterile culture bottle 7 for receiving drainage liquid, and the sterile culture bottle 7 is assembled inside the side bag 2.

[0029] The multifunctional medical drainage bag 100 of the present invention is equipped with a multi-way connecting assembly 5 at the liquid inlet tube 3, so that the drainage bag 100 can be adapted to drainage tubes of various specifications, thereby increasing the applicability of the drainage bag 100; by providing a side bag 2, a sterile culture bottle 7 is provided inside the side bag 2, and when sampling is required, the drainage liquid enters the sterile culture bottle 7, and after the sampling is completed, the second cylindrical rotary switch head 8 is rotated to close the liquid passage 61 of the connecting tube 6, and the sterile culture bottle 7 is removed, and the sterile culture bottle 7 can be sent for bacterial culture or testing, and the drainage liquid will not leak, and there is no risk of pollution.

[0030] In the present invention, the multi-way connection assembly 5 includes a main connection pipe 51, a plurality of connectors 52, and a first cylindrical rotary switch head 53; the main connection pipe 51 is a hollow tube body and the rear end is connected to the top of the liquid inlet pipe 3; the plurality of connectors 52 are circumferentially distributed along the radial direction of the main connection pipe 51 and are connected to the main connection pipe 51; the first cylindrical rotary switch head 53 is rotatably sleeved in the main connection pipe 51, and the first cylindrical rotary switch head 53 includes a first rotary sleeve 531, the first rotary sleeve 531 is a hollow structure, and a connection port 532 for connecting any connector 52 is provided on the tube wall of the first rotary sleeve 531. The multi-way connection assembly 5 is used to connect with drainage tubes of different specifications to increase the applicability of the drainage bag 100. The medical staff rotates the first cylindrical rotary switch head 53 to connect the connecting port 532 to different connecting heads 52 as needed; when the drainage is completed, the first cylindrical rotary switch head 53 is rotated to make the connecting port 532 face downward, and the liquid inlet tube 3 is disconnected from each connecting head 52, so that the drainage bag 100 and the drainage tube can be separated, and the drainage liquid will not drip.

[0031] In the present invention, the connector 52 includes a first threaded connector 521, a second threaded connector 522, and a straight connector 523. The diameter of the first threaded connector 521 is larger than the diameter of the second threaded connector 522. The first threaded connector 521 is detachably connected to a first cover, the second threaded connector 522 is detachably connected to a second cover, and the straight connector 523 is detachably connected to a third cover. The cover is used to seal each connector 52, which is more hygienic. The first threaded connector 521 has a first internal thread formed on its inner wall, and the second threaded connector 522 has a second internal thread formed on its inner wall.

[0032] In the present invention, the first cylindrical rotary switch head 53 also includes a first triangular control part 532 fixedly connected to the end of the first rotary sleeve 531, and the first triangular control part 532 is marked with a first indicator arrow 533, and the direction of the first indicator arrow 533 is the same as the direction of the connection port 532. When the first indicator arrow 533 is upward, the connection port 532 is connected to the first threaded connector 521; when the first indicator arrow 533 is leftward, the connection port 532 is connected to the second threaded connector 522; when the first indicator arrow 533 is rightward, the connection port 532 is connected to the straight connector 523. The setting of the first triangular control part 532 is convenient for medical staff to rotate the first rotary sleeve 531, and the setting of the first indicator arrow 533 enables medical staff to accurately switch the connection port 532, greatly improving the convenience of operation of the multi-way connection assembly 5.

[0033] In the present invention, the outer wall of the first rotating sleeve 531 is formed with a first annular protrusion 534, and the inner wall of the main connecting pipe 51 is formed with a first annular groove 511 for cooperating with the first annular protrusion 534. The arrangement of the first annular protrusion 534 and the first annular groove 511 can limit the first cylindrical rotating switch head 53 and the main connecting pipe 51 to only rotate relative to each other in the radial direction without axial sliding, so that the connecting port 532 can be accurately aligned with each connecting head 52 during the rotation process; and can also prevent the first cylindrical rotating switch head 53 from sliding out of the main connecting pipe 51.

[0034] In the present invention, a liquid passage 61 is formed inside the connecting tube 6 for the drainage liquid to enter the sterile culture bottle 7, and a second cylindrical rotary switch head 8 for connecting and disconnecting the liquid passage 61 is sleeved perpendicular to the length direction of the connecting tube 6. The second cylindrical rotary switch head 8 is arranged in the middle and upper part of the connecting tube 6 and above the sterile culture bottle 7. The connection and disconnection of the liquid passage 61 are realized by rotating the second cylindrical rotary switch head 8 radially 90 degrees. During drainage, the liquid passage 61 is connected to the sterile culture bottle 7 so that the drainage liquid can enter; after the drainage is completed, the second cylindrical rotary switch head 8 is rotated radially 90 degrees to disconnect the liquid passage 61, and then the sterile culture bottle 7 is disassembled. When it is necessary to sample multiple bottles of drainage liquid, a new sterile culture bottle 7 is threadedly connected to the connecting tube 6, and then the second cylindrical rotary switch head 8 is rotated radially 90 degrees again to connect the liquid passage 61, so that the drainage liquid enters the sterile culture bottle 7 again. The provision of the second cylindrical rotary switch head 8 can increase the convenience of sampling the drainage liquid. Disconnecting the liquid passage 61 when disassembling the sterile culture bottle 7 can prevent the drainage liquid from spraying out and reduce pollution.

[0035] In the present invention, the second cylindrical rotary switch head 8 includes a second rotary sleeve 81, and the second rotary sleeve 81 is formed with a connecting cavity 811 for connecting and disconnecting the liquid passage 61. When the connecting cavity 811 and the liquid passage 61 are in a straight line, the liquid passage 61 and the sterile culture bottle 7 are in a connected state, and when the connecting cavity 811 and the liquid passage 61 are perpendicular, the liquid passage 61 and the sterile culture bottle 7 are disconnected.

[0036] In the present invention, the second cylindrical rotary switch head 8 further includes a second triangular control portion 82 fixedly connected to the end of the second rotary sleeve 81, and a second indicator arrow 83 is marked on the second triangular control portion 82, and the direction of the second indicator arrow 83 is the same as that of the connecting cavity 811. When the second indicator arrow 83 is set upward or downward, the liquid passage 61 is in a connected state; when the second indicator arrow 83 is set to the left or right, the liquid passage 61 is in a disconnected state.

[0037] In the present invention, the outer wall of the second rotating sleeve 81 is formed with a second annular protrusion 812, and the inner wall of the connecting tube 6 is formed with a second annular groove 62 for cooperating with the second annular protrusion 812. The arrangement of the second annular protrusion 812 and the second annular groove 62 can limit the second cylindrical rotating switch head 8 and the connecting tube 6 to only radial relative rotation without axial sliding, thereby enabling the connecting cavity 811 to be accurately aligned with the liquid passage 61 during the rotation process; and can also prevent the second cylindrical rotating switch head 8 from slipping out of the connecting tube 6.

[0038] In the present invention, the connecting tube 6 is threadedly connected to the sterile culture bottle 7. The threaded connection is convenient for disassembly and assembly of the connecting tube 6 and the sterile culture bottle 7, and the connection stability and sealing performance of the two are good.

[0039] In the present invention, the drainage bag 100 is a transparent drainage bag 100, and the surface of the transparent drainage bag 100 is marked with scale lines to facilitate observation of the volume of the drainage liquid. The transparent drainage bag 100 is made of any one of polyvinyl chloride, ABS, and polypropylene.

[0040] In the present invention, the heat-pressed edge of the side bag 2 is provided with an easy-tear line 21. When not in use, the sterile culture bottle 7 is connected to the connecting tube 6 and wrapped inside the side bag 2, reducing air contact and being more hygienic. When in use, the side bag 2 is torn open from the easy-tear line 21 to check the connection status of the connecting tube 6 and the sterile culture bottle 7.

[0041] In the present invention, a hanging line 9 is also provided on the top of the drainage bag 100, so that the drainage bag 100 can be hung on a bracket or bedside during drainage, so that the drainage bag 100 can always be in a vertical state, which is convenient for the drainage liquid to flow.

[0042] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention.
