A second magnet 206 is symmetrically fixed on the movable frame 204, and a magnetic attraction structure is formed between the second magnet 206 and the first magnet 203. A vertical rod 207 is fixed at the lower end of the movable frame 204, and an inclined block 208 is fixed at the lower end of the vertical rod 207. Through the movement of the convex shaft 306 and the sliding effect between the convex shaft 306 and the inclined block 208, the movable frame 204 is forced to move, thereby driving the seal 205 to move, so that the seal 205 seals the annular plates 202 at different positions.

[0032] The liquid storage structure 4 includes a liquid storage bag 401, a liquid discharge valve port 402, a connector 403, a sealing plug 404, a push rod 405, a slide rod 406, a cross plate 407 and a second spring 408. The liquid storage bag 401 is fixed with a liquid discharge valve port 402 at the lower end, and the liquid storage bag 401 is fixed with a connector 403 at the upper end, and the connector 403 is connected to the threaded joint 301 through a thread; a sealing plug 404 is arranged in the connector 403, and the sealing plug 404 and the connector are connected. 403 cooperates to achieve sealing, and a push rod 405 is fixed symmetrically on the left and right of the sealing plug 404, and the push rod 405 is slidably connected to the connector 403; a sliding rod 406 is fixed to the lower end of the sealing plug 404, and the sliding rod 406 is slidably connected to the horizontal plate 407, and the horizontal plate 407 is fixed in the connector 403; the sealing plug 404 and one end of the second spring 408 are fixed to each other, and the other end of the second spring 408 is fixed to the horizontal plate 407;

[0033] When using the clinical body fluid monitoring and early warning device and the monitoring and early warning method thereof, if Figure 1-Figure 7As shown, first, the shunt tube 201 is connected to the body fluid drainage device, and then the liquid storage bag 401 is installed. The installation and fixation of the liquid storage bag 401 can be achieved through the threaded connection between the connector 403 and the threaded joint 301. During the connection process between the connector 403 and the threaded joint 301, when the push rod 405 contacts the fixing ring 305, the connector 403 is continuously rotated, so that the push rod 405 is forced to move downward relative to the connector 403, thereby driving the sealing plug 404 to move downward, and the sliding guide effect between the sliding rod 406 and the cross plate 407 can ensure that the sealing plug 404 is 4, so that the sealing plug 404 is separated from the connector 403, and the sealing effect is automatically released until the connector 403 contacts the fixing ring 305 to achieve positioning, which is convenient for subsequent body fluid to enter the liquid storage bag 401 for collection. According to the above principle, the installation of two liquid storage bags 401 can be achieved, and at this time, the second spring 408 is in a contracted state. When the blood in the subsequent liquid storage bag 401 is full, the connector 403 is separated from the threaded joint 301. At this time, the second spring 408 is used to reset the sealing plug 404 and cooperate with the connector 403 to achieve sealing, effectively preventing blood from spilling out.

[0034] The upper end surface of the housing 1 is provided with a controller 101, and a buzzer 102 and a warning light 103 are also provided with the upper end surface of the housing 1, and the buzzer 102 and the warning light 103 are electrically connected to the controller 101; the monitoring mechanism 3 comprises a threaded joint 301, a top plate 302, a first spring 303, a weighing sensor 304, a fixing ring 305, a convex shaft 306 and a connecting pipe 307, the threaded joint 301 is slidably connected to the housing 1, and the threaded joint 301 is symmetrically distributed about the center line of the housing 1, and the threaded joint 301 is 1 is fixed with a top plate 302 at the upper end, and a fixing ring 305 is fixed in the threaded joint 301; one end of a first spring 303 is fixed on the top plate 302, and the other end of the first spring 303 is fixed on a weighing sensor 304, and the weighing sensor 304 is fixed on the housing 1, and the weighing sensor 304 is electrically connected to the controller 101; a convex shaft 306 is fixed on the top plate 302, and the convex shaft 306 contacts with the inclined surface block 208 and can slide, and the top plate 302 is connected to the shunt pipe 201 through a connecting pipe 307;

[0035] After the liquid storage bag 401 is installed (the liquid storage capacity of the liquid storage bag 401 is slightly greater than the preset value), Figure 1-Figure 7 As shown, the gravity data detected by the weighing sensor 304 is cleared by the controller 101 to ensure the accuracy of the subsequent detection data. After the preparation work is completed, the blood in the patient's inner cavity can be sucked out by starting the body fluid drainage device, as shown in FIG. Figure 4As shown, at this time, the left sealing member 205 and the left annular plate 202 are in a separated state, and the right sealing member 205 and the right annular plate 202 are in a matched sealing state, so that the blood entering the shunt tube 201 enters the left liquid storage bag 401 through the connecting tube 307, the threaded joint 301 and the connector 403 for collection, and as the weight of the blood in the liquid storage bag 401 increases, the threaded joint 301 is forced to slide downward, so that the first spring 303 is forced to contract, and with the action of the weighing sensor 304, the weight of the collected blood in the liquid storage bag 401 can be monitored in real time, and the relevant data can be fed back to the controller 101. When the weight of the blood in the liquid storage bag 401 is ≥ the preset value, the controller 101 controls the buzzer 102 and the warning light 103 to start, realizing the sound and light alarm effect, so as to realize the warning effect of medical staff;

[0036] When the weight of blood in the liquid storage bag 401 increases and the threaded connector 301 slides downward, Figure 1-Figure 6 As shown, at this time, the top plate 302 and the convex shaft 306 move downward synchronously. When the convex shaft 306 contacts and slides with the inclined surface block 208, the inclined surface block 208 is forced to move to the right, thereby driving the vertical rod 207, the movable frame 204 and the sealing member 205 to move to the right. At this time, the second magnet 206 on the right is separated from the first magnet 203 on the right, and the second magnet 206 on the left is close to the first magnet 203 on the left. When the second magnet 206 on the left is attracted to the first magnet 203 on the left, the left sealing member 205 is in cooperation with the left annular plate 202. The right sealing member 205 is in a sealed state and the right annular plate 202 is in a separated state, so that the blood in the shunt tube 201 enters the right liquid storage bag 401 through the connecting tube 307, the threaded joint 301 and the connecting head 403 for collection, thereby realizing automatic shunt effect and facilitating blood collection. At this time, medical staff can disassemble and replace the left liquid storage bag 401 to effectively avoid blood splashing and improve the convenience of using the device. This is the working principle of the clinical body fluid monitoring and early warning device and its monitoring and early warning method.
