[0002] Clinically, the negative pressure drainage bottle, also known as the suction bottle, is generally used in the ward. It is mainly used for medical drainage, discharging dirty blood and gas, etc. The negative pressure drainage device works on the principle of vacuum, generating negative pressure in the human body cavity to guide the liquid in the cavity and play the role of sewage discharge and purification. The negative pressure suction device is mainly composed of a hose and a negative pressure bottle. There is a certain negative pressure in the negative pressure drainage bottle itself. Connect the hose to the negative pressure drainage bottle, and then connect the other end of the hose to the patient's drainage tube. Through the negative pressure in the negative pressure drainage bottle, the accumulated fluid or flatulence in the patient's body is sucked out, and through the drainage of the hose, it is guided into the negative pressure drainage bottle;
[0003] As the liquid or gas in the negative pressure drainage bottle increases, when the liquid rises to a certain height, the negative pressure in the negative pressure drainage bottle will gradually decrease and disappear. At this time, medical staff need to replace the new negative pressure drainage bottle. If the medical staff or family members cannot know in time, it will lead to the stop of drainage and affect the patient's recovery treatment. Therefore, it is necessary to design a reminder device that can automatically remind medical staff to replace the drainage bottle after the negative pressure in the negative pressure drainage bottle disappears, and it is also applicable to the drainage of gas.

[0014] It is given by Figures 1 to 6 including a connecting tube 1 in the front-back axial direction. Annular slots 2 are coaxially provided at the front and rear ends of the connecting tube 1 respectively. The openings of the two slots 2 face away from each other. A plurality of sliders 3 evenly distributed along the circumferential direction of the connecting tube 1 are slidably connected to the front and rear ends of the connecting tube 1 respectively. An arc-shaped extrusion block 4 is fixed at one end of the slider 3 facing the slot 2. An alarm 5 is provided at the right end of the connecting tube 1. A main switch 6 is provided at the upper end of the alarm 5. A horizontal bar 7 in the left-right direction is provided in the connecting tube 1. A support airbag 8 is fixed at the rear end of the horizontal bar 7. A retaining ring 9 is fixed in the connecting tube 1 behind the support airbag 8. A retaining disc 10 that can be inserted into the inner side of the retaining ring 9 is fixed at the rear end of the support airbag 8. The retaining disc 10 and the retaining ring 9 can block the connecting tube 1. A relief groove 11 is provided on the right side of the connecting tube 1. The relief groove 11 can communicate with the inside of the support airbag 8 and is provided with a pressure sensing switch 12.
[0015] In order to facilitate the control of the movement of the slider 3, the end of the front slider 3 away from the slot 2 is an inclined surface with a higher front and a lower back, and the multiple sliders 3 on the front and rear sides are symmetrical front and back. The front and rear ends of the connecting tube 1 are respectively threadedly connected with push rings 13, and the push ring 13 can contact the inclined surface of the slider 3 on its corresponding side.
[0016] In order to facilitate the resetting of the slider 3, a plurality of pressing grooves 14 corresponding to the slider 3 are respectively opened at the front and rear ends of the slider 3, and a pressing plate 15 inserted into the pressing groove 14 is provided on the slider 3. The pressing plate 15 is connected to the pressing groove 14 via an inverted U-shaped elastic sheet 16.
[0017] In order to facilitate the use of the extrusion block 4 , a protrusion is provided on the side of the extrusion block 4 facing the slot 2 .
[0018] In order to facilitate the connection between the supporting airbag 8 and the clearance groove 11, a connecting cavity 17 is opened on the cross bar 7. The rear side of the connecting cavity 17 is connected to the supporting airbag 8 through the connecting groove 18, and the right end of the connecting cavity 17 is connected to the clearance groove 11 through the connecting hole 19.
[0019] In order to facilitate the sliding of the baffle plate 10 , the support airbag 8 and the crossbar 7 are provided with notches, in which a guide column 20 is slidably connected, and the upper end of the guide column 20 is fixedly connected to the baffle plate 10 .
[0020] When the utility model is in use, the medical staff rotates the push ring 13 on the rear side clockwise to move the push ring 13 on the rear side forward and disengage the slider 3. Under the action of the elastic sheet 16, the multiple sliders 3 slide toward the side away from the connecting groove 18, and the extrusion block 4 moves out of the connecting groove 18. At the same time, the push ring 13 on the front side is rotated counterclockwise to move the slider 3 on the front side through the above process.
