[0042] The diameter of the first turntable 15 is larger than the diameter of the second turntable 16. The gap between the first turntable 15 and the first housing 1 forms an inner annular cavity, and the gap between the second turntable 16 and the second housing 5 forms an outer annular cavity. The cross-sectional height of the inner annular cavity in the first turntable 15 is smaller than the cross-sectional height of the outer annular cavity in the second turntable 16. These are used to wind up thicker drainage tubes and thinner nasobiliary tubes, respectively.

[0043] A fixing frame 11 is fixedly installed inside the first housing 5, and a connecting frame 12 is fixedly installed on the fixing frame 11. The fixing frame 11 is a long strip plate structure, and the two ends of the fixing frame 11 are fixedly connected to the inner wall of the first housing 5. The connecting frame 12 is a semi-arc frame body, used to clamp the connector of the nasobiliary tube 18 and the drainage tube.

[0044] A hook 7 is provided on the outer wall of the second housing 5.

[0045] As a specific example of the above embodiments, the fixing structure 17 includes a fixing groove 171 and a fixing strip 172. A plurality of fixing grooves 171 are opened on the outer wall of the first housing 1, and a plurality of fixing strips 172 corresponding to the fixing grooves 171 are provided on the inner wall of the second housing 5. The fixing strips 172 are inserted into the corresponding fixing grooves 171.

[0046] As a specific example of the above embodiments, the depth of the fixing groove 171 gradually decreases from the inside of the first housing 1 to the outside of the first housing 1.

[0047] As a specific example of the above embodiment, the thin tube opening 3 is composed of a second thin tube groove 32 and a first thin tube groove 31. After the first housing 1 and the second housing 5 are inserted, the second thin tube groove 32 and the first thin tube groove 31 can form the thin tube opening 3. The first thin tube groove 31 is fixedly disposed on the first housing 1 and communicates with the inside of the first housing 1. The first thin tube groove 31 opens to the side of the first housing 1 that is open. The second thin tube groove 32 is fixedly disposed on the second housing 5 and communicates with the inside of the second housing 5. The second thin tube groove 32 opens to the side of the second housing 5 that is open.

[0048] As a specific example of the above embodiment, the coarse pipe opening 6 is composed of a second coarse pipe groove 62 and a first coarse pipe groove 61. After the first housing 1 and the second housing 5 are inserted, the second coarse pipe groove 62 and the first coarse pipe groove 61 can form the coarse pipe opening 6. The first coarse pipe groove 61 is fixedly disposed on the first housing 1 and communicates with the interior of the first housing 1. The first coarse pipe groove 61 opens to the side of the first housing 1 that is open. The second coarse pipe groove 62 is fixedly disposed on the second housing 5 and communicates with the interior of the second housing 5. The second coarse pipe groove 62 opens to the side of the second housing 5 that is open.

[0049] As a specific example of the above embodiments, the outer wall of the second housing 5 is provided with a mark indicating the rotation direction of the second throttle 9, and the outer wall of the first housing 1 is provided with a mark indicating the rotation direction of the first throttle 2.

[0050] As a specific example of the above embodiments, the outer side of the second housing 5 has a through groove 19 for the second rotating shaft 8 to pass through and for the second rotating shaft 8 to pass through, and the outer side of the first housing 1 has a through groove 19 for the first rotating shaft 4 to pass through and for the first rotating shaft 4 to pass through.

[0051] As a specific example of the above embodiments, a gasket 10 is provided in the through groove 19 to reduce friction and prevent wear on the entire housing.

[0052] As a specific example of the above embodiments, the centerline of the thin tube opening 3 is tangent to the entire shell, and the centerline of the thick tube opening 6 is tangent to the entire shell, so as to avoid excessive pressure when the pipeline enters, which would affect the normal infusion.

[0053] In use, firstly, the first housing 1 and the second housing 5 are disassembled. At this time, the thin tube opening 3 and the thick tube opening 6 are disassembled simultaneously. The connectors of the nasobiliary tube 18 and the drainage tube are snapped onto the connecting bracket 12 inside the first housing 1. The thicker drainage tube 18 is pulled to the second fixing buckle 14 of the second turntable 16 and inserted into the second fixing buckle 14 through the notch. Then, it extends out from the outer thick tube opening 6. The thicker drainage tube is pulled to the first fixing buckle 13 of the first turntable 15 and inserted into the first fixing buckle 13 through the notch. Then, it extends out from the inner thin tube opening 3. Then, the first housing 1 and the second housing 5 are put together and fixed by the fixing groove 171 and the fixing strip 172, so that the entire housing is installed and the first housing 1 and the second housing 5 cannot rotate relative to each other.

[0054] When the drainage tube is too long and needs to be stored, the medical staff turns the second handle 9. The rotation of the second handle 9 drives the second rotating shaft 8 to rotate, and the rotation of the second rotating shaft 8 drives the second rotating plate 16 to rotate. Since the distal end of the drainage tube is fixed on the connecting frame 12, the second fixing buckle 14 on the second rotating plate 16 moves the drainage tube, allowing the drainage tube to enter from the coarse tube opening 6 and be wrapped and stored along the second rotating plate 16, shortening the length of the drainage tube on the outside.

[0055] When the nasobiliary duct needs to be stored, the medical staff turns the first handle 2, which drives the first shaft 4 to rotate. The first shaft 4 then drives the first turntable 15 to rotate. Since the distal end of the nasobiliary duct is fixed on the connecting frame 12, the first fixing buckle 13 on the first turntable 15 moves the nasobiliary duct when it rotates, allowing the nasobiliary duct to enter from the narrow tube opening 3 and be wound around the first turntable 15 for storage, shortening the length of the nasobiliary duct inside. After storage, the entire shell is suspended on the patient's bed frame by the hook 7.

[0056] Example 2

[0057] Example 2 is a preferred example, such as Figure 7 As shown, a hinge seat is provided on the second housing 5, and a hinge shaft is dampedly connected to the hinge seat. The hook 7 and the hinge shaft are fixedly connected.

[0058] When in use, the angle of hook 7 can be adjusted so that the entire housing can be hung on railings at different angles.

[0059] In the description of this specification, references to terms such as "an embodiment," "example," "specific example," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
