The outer peripheral surface of the bottle cap 12 is provided with anti-slip grooves.

[0031] The suspension mechanism 2 further includes a clamping rod 23 and a threaded sleeve 24. A through hole penetrating the bottom of the clamping groove 22 is provided on the bottom of the groove. The threaded sleeve 24 is arranged on the through hole. An external thread is formed on the outer circumference of the clamping rod 23. The threaded sleeve 24 has an internal thread matched with the external thread of the clamping rod 23. The clamping rod 23 is movably arranged at the bottom of the clamping groove 22 through threaded matching. An operating handle 25 is provided at the bottom of the clamping rod 23. Anti-slip grooves are provided on the outer circumference of the operating handle 25. A suction cup 26 is provided at the top of the clamping rod 23.

[0032] The fixing rod 20 is provided with a screw hole, in which a locking bolt 27 is arranged. The locking bolt 27 can be switched between a locking position and a loosening position through threaded engagement.

[0034] Continue to refer to Figures 1 to 6 When the utility model is used, when the patient lies on the bed, the drainage bottle 10 is fixedly installed on the edge of the bed using the clamping groove 22, and the inner wall of the groove top of the clamping groove 22 is tightly attached to the upper surface of the edge of the bed. The medical staff rotates the clamping rod 23 by operating the handle 25, so that the clamping rod 23 moves upward until the suction cup 26 at the top of the clamping rod 23 is squeezed on the lower surface of the edge of the bed. The clamping rod 23 cooperates with the upper surface of the clamping groove 22 to clamp the edge of the bed in the clamping groove 22, so that the drainage bottle 10 is fixed to the edge of the bed. Since the clamping groove 22 is perpendicular to the central axis of the drainage bottle 10, when the clamping groove 22 horizontally clamps the edge of the bed, the drainage bottle 10 can remain perpendicular to the ground, thereby preventing the drainage bottle 10 from tilting and causing air to enter the patient's chest cavity. The lifting rod 21 and the fixing rod 20 can cooperate to adjust the distance between the clamping groove 22 and the drainage bottle 10, and fix it with the locking bolt 27 to adjust the position of the drainage bottle 10, so that the drainage bottle 10 is in a low position, forming a liquid level difference, which is beneficial to drain the effusion in the patient's chest cavity, and can be adjusted according to the height of the bed to improve the application range of the device.

[0035] A clamping mechanism 3 is provided above the clamping groove 22, and the drainage tube 11 is placed on the first semicircular groove 300 of the first clamping plate 30, and the second clamping plate 31 is arranged on the first clamping plate 30, so that the second semicircular groove 310 on the second clamping plate 31 and the first semicircular groove 300 on the first clamping plate 30 form a complete circular groove, and the second clamping plate 31 is fixed between the two mounting rods 33 by the fixing pin 35, so that the drainage tube 11 is clamped and positioned by the first clamping plate 30 and the second clamping plate 31, and the circular groove formed between the first clamping plate 30 and the second clamping plate 31 can guide the drainage tube 11 and reduce the bending of the drainage tube 11. When the patient needs to leave the bed or the tube becomes detached, the medical staff first folds the drainage tube 11 in half and places it on top of the second splint 31, unplugs the fixing pin 35 of the third splint 32, moves the third splint 32 to a position that contacts and presses the drainage tube 11, and reinserts the fixing pin 35. The second splint 31 and the third splint 32 fix the drainage tube 11, and the medical staff does not need to pinch the drainage tube with their hands, freeing their hands and facilitating subsequent treatment by the medical staff.

[0036] The above is only a specific implementation of the present utility model, but the design concept of the present utility model is not limited to this. Any non-substantial changes to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
