[0038] See also Figure 3 , Figure 5-8As shown, the extrusion assembly 5 includes a counterweight plate 501 and a moving block 506. The moving block 506 is located outside the installation box 3. The counterweight plate 501 is disc-shaped. The bottom ends of multiple drip tubes 402 all penetrate the counterweight plate 501. The diameter of the counterweight plate 501 is smaller than the inner diameter of the annular top plate 4033. A pull rope 504 is connected to the center of the top of the counterweight plate 501.

The upper surface of the upper partition plate 303 A fixing block 5052 is welded at the opening of the installation box 3, and the two ends of the second guide wheel 505 are rotatably connected to the inner wall of the installation box 3 and the outer wall of the fixing block 5052 through the shaft rod 5051 respectively. A square through hole 301 is opened on the side wall of the installation box 3, and a symmetrical first guide wheel 3011 is rotatably installed in the through hole 301. The pull rope 504 passes through the upper partition 303 and passes through the installation box 3 along the second guide wheel 505 and between the two first guide wheels 3011;

[0039] The moving block 506 contacts the outer wall of the installation box 3. The outer wall of the installation box 3 is fixed with slide rails 302 above and below the through hole 301. The moving block 506 is symmetrically provided with slide grooves 5061 on one side close to the installation box 3. The two slide grooves 5061 are slidably connected to the slide rails 302. The outer wall of the moving block 506 is provided with a groove 5062 between the two slide grooves 5061. A cylindrical rod 5063 is rotatably installed in the end of the groove 5062 away from the through hole 301. The end of the pull rope 504 is fixedly connected to the outer wall of the cylindrical rod 5063. The groove 506 2 is larger than the cross-sectional diameter of the pull rope 504, and a plurality of drip tubes 402 are all equipped with electromagnetic valves, and a button electrically connected to the electromagnetic valve is provided on the lower surface of the upper partition 303, and the upper surface of the counterweight plate 501 is in contact with the button, and a guide rod 502 is fixedly connected to one side of the upper surface of the counterweight plate 501, and a storage sleeve 503 is vertically fixed in the water storage tank 401, and both ends of the storage sleeve 503 are fixedly connected to the inner wall of the water storage tank 401, and the top end of the guide rod 502 passes through the upper partition 303 and the water storage tank 401 in sequence and is slidably connected to the inner wall of the storage sleeve 503;

[0040] The top ends of the two guide pipes 7 both pass through the lower partition 304, and water seals are installed in the two guide pipes 7. The structure of the water seal adopts a spring-type floor drain structure. The weighing device 6 is installed at the center of the lower surface of the lower partition 304 by bolts. The inner wall of the water receiving box 405 is installed with a water pump 406 by bolts. The suction port of the water pump 406 is connected to a water pump pipe 4061. The bottom end of the water pump pipe 4061 is 1 cm away from the inner bottom wall of the water receiving box 405. The output port of the water pump 406 is connected to the water supply pipe 407. The water supply pipe 407 passes through the lower partition 304 and the upper partition 303 in turn. A liquid level sensor 408 is vertically installed on one side of the inner top wall of the water receiving box 405. The inner top wall of the pull-out bin 403 is fixed with an annular top plate 4033. The inner wall of the pull-out bin 403 is evenly fixed. There are four vertical clamping rods 4032, and the four clamping rods 4032 are all in squeeze contact with the outer wall of the sponge 404. The inner wall of the opening of the installation box 3 is provided with a limiting groove 305. The two side walls of the pull-out bin 403 are fixed with limiting blocks 4031, and the two limiting blocks 4031 are slidably connected with the limiting groove 305. After the panel 102 is disassembled, the pull-out bin 403 can be pulled out from the lower partition 304 alone, and the sponge 404 inside can be replaced and pushed in again. The limiting blocks 4031 and the limiting groove 305 can ensure the pushing position when the pull-out bin 403 is pushed in, and the situation of pushing in too much or too little can be ensured. In addition, the clamping rods 4032 and the annular top plate 4033 can increase friction and limit when installing the sponge 404.

[0041] When the components of the equipment are to be maintained, the medical staff removes the panel 102 from the box body 1 with a tool, and the panel 102 drives the top block 1021 and the push plate 1022 to move, so that the top block 1021 and the push plate 1022 are separated from the drawer 403 and the plug-in slot 5064 of the moving block 506 respectively. At this time, the gravity of the counterweight plate 501 pulls the pull rope 504 to move along the second guide wheel 505 and the first guide wheel 3011, and the moving pull rope 504 passes through the cylindrical rod 5063 drives the moving block 506 to move along the slide rail 302, and the counterweight plate 501 moves downward to squeeze the sponge 404 in the drawer 403. Since the counterweight plate 501 is separated from the button, the solenoid valve at the drip tube 402 is closed and no water drips. At the same time, the counterweight plate 501 moving downward drives the guide rod 502 to move, so that the guide rod 502 moves out of the storage sleeve 503, avoiding the counterweight plate 501 from deflecting when moving, and the counterweight plate 501 squeezes out the water in the sponge 404.

[0042] The squeezed water gathers in the guide pipe 7. Under the weight of the water, the water seal in the pipe opens, allowing the water to fall into the water receiving box 405. After the liquid level sensor 408 senses the water level, it will send a signal to the control motherboard, which will send an electrical signal to start the water pump 406, so that the water pump 406 can send water back into the water storage tank 401 through the water pump pipe 4061 and the water supply pipe 407. Finally, after the maintenance is completed, the panel 102 is reinstalled, the top block 1021 abuts against the pull-out bin 403, and the end of the push plate 1022 is inserted into the plug-in slot 5064, pushing the moving block 506 to move along the slide rail 302. The moving block 506 lifts the counterweight plate 501 through the pull rope 504. At this time, the weight value returns to zero, and water dripping and detection are performed again, so that when disassembling for maintenance, the water in the sponge 404 is automatically squeezed out and the weight value is reset.

[0043] The working principle of the present invention is as follows: when the negative pressure wound therapy device is in normal use or storage, the water in the internal water storage tank 401 will slowly drip onto the sponge 404 placed in the drawer 403 through multiple drip tubes 402, and the sponge 404 will absorb the dripping water drops, and the weighing device 6 at the lower partition 304 will monitor the weight of the upper sponge 404 in real time, and send the monitored value to the control mainboard, and then the control mainboard will present the value on the display 1023. As time goes by, the more water the sponge 404 absorbs, the heavier the monitored weight will be, and the larger the value is, the longer the negative pressure wound therapy device has not been maintained;

[0044] When the components of the equipment are to be maintained, the medical staff removes the panel 102 from the box body 1 with a tool, and the panel 102 drives the top block 1021 and the push plate 1022 to move, so that the top block 1021 and the push plate 1022 are separated from the drawer 403 and the plug-in slot 5064 of the moving block 506 respectively. At this time, the gravity of the counterweight plate 501 pulls the pull rope 504 to move along the second guide wheel 505 and the first guide wheel 3011, and the moving pull rope 504 passes through the cylindrical rod 5063 drives the moving block 506 to move along the slide rail 302, and the counterweight plate 501 moves downward to squeeze the sponge 404 in the drawer 403. Since the counterweight plate 501 is separated from the button, the solenoid valve at the drip tube 402 is closed and no water drips. At the same time, the counterweight plate 501 moving downward drives the guide rod 502 to move, so that the guide rod 502 moves out of the storage sleeve 503, avoiding the counterweight plate 501 from deflecting when moving, and the counterweight plate 501 squeezes out the water in the sponge 404.

[0045] The squeezed water gathers in the guide pipe 7. Under the weight of the water, the water seal in the pipe opens, allowing the water to fall into the water receiving box 405. After the liquid level sensor 408 senses the water level, it will send a signal to the control motherboard, and the control motherboard sends an electrical signal to start the water pump 406, so that the water pump 406 sends water back into the water storage tank 401 through the water pump pipe 4061 and the water supply pipe 407. Finally, after the maintenance is completed, the panel 102 is reinstalled, the top block 1021 abuts against the pull-out bin 403, and the end of the push plate 1022 is inserted into the plug-in slot 5064, pushing the moving block 506 to move along the slide rail 302. The moving block 506 lifts the counterweight plate 501 through the pull rope 504. At this time, the weight value returns to zero, and water dripping and detection are performed again.
