By setting the display screen 4, the time data in the time controller 5, the liquid level data detected by the liquid level sensor 301 and the distance data detected by the distance measuring sensor 907 can be displayed in real time.

[0018] See also Figure 2 and Figure 6 A gear 902 is fixedly installed at the output end of the second motor 901, and a screw sleeve 904 is installed on the top of the housing 1 through a sealed bearing. A gear ring 905 is fixedly sleeved on the surface of the screw sleeve 904, and the gear ring 905 is meshed with the gear 902. By setting the gear 902 and the gear ring 905, a meshing transmission effect can be achieved, and the screw sleeve 904 can be continuously rotated under the drive of the second motor 901.

[0019] See also Figure 2 and Figure 6 The inner cavity of the screw sleeve 904 is threadedly connected with the hollow screw 903. By setting the hollow screw 903 and the screw sleeve 904, the role of thread transmission can be achieved. When the screw sleeve 904 rotates continuously, the hollow screw 903 will produce up and down displacement. The bottom of the hollow screw 903 penetrates to the bottom of the inner cavity of the adjustment cavity 8, and the top of the surface of the hollow screw 903 is fixedly connected with a connecting frame 906.

[0020] See also Figure 2 and Figure 6 The bottom of the connecting frame 906 passes through the shell 1 and is in sliding contact with the shell 1 and is sealed. The surface of the connecting frame 906 is fixedly connected to the distance sensor 907. By setting the connecting frame 906, the up and down displacement of the hollow screw 903 can be guided and the fixed installation requirements of the distance sensor 907 can be met.

[0021] See also Figure 2 , Figure 3 and Figure 4The support plate 201 is fixedly installed on the top of the shell 1. By setting the support plate 201, the drainage tube 204 can be installed at an angle, and then with the assistance of gravity, it is beneficial to transfer the accumulated fluid through the drainage tube 204. The front side of the support plate 201 is provided with an anti-skid groove 203 used in conjunction with the drainage tube 204. By setting the anti-skid groove 203, the drainage tube 204 can be anti-skid. While ensuring that the liquid in the drainage tube 204 can flow well, the drainage tube 204 is prevented from bending at will. The left end of the drainage tube 204 is connected to the top of the infusion tube 14.

[0022] See also Figure 2 , Figure 3 and Figure 4 A positioning seat 206 is fixedly connected to the left side of the support plate 201. By setting the positioning seat 206, the drainage tube 204 can be guided and positioned to prevent the drainage tube 204 from expanding and displacing outward at will. The first motor 205 is bolted to the back surface of the positioning seat 206. The output end of the first motor 205 is fixedly connected to a rotating rod 209. A movable frame 208 is fixedly sleeved on the surface of the rotating rod 209. An extrusion wheel 207 is movably installed on the outer side of the surface of the movable frame 208. By setting the extrusion wheel 207 and the movable frame 208, they can rotate together with the rotating rod 209, and then the extrusion wheel 207 can be driven by the first motor 205 to rotate continuously, and the extrusion wheel 207 is in close contact with the drainage tube 204.

[0023] See also Figure 2 , Figure 3 and Figure 4 The top and bottom of the support plate 201 are both provided with empty grooves 202, and the empty grooves 202 are in communication with the anti-slip grooves 203. By providing the empty grooves 202, the space requirement for the drainage tube 204 to pass through can be met.

[0024] See also Figure 2 and Figure 5 The liquid level sensor 301 is fixedly mounted on the top of the shell 1. By setting the liquid level sensor 301, the liquid level height in the main liquid storage bottle 303 can be detected in real time. The liquid level sensor 301 is located directly above the main liquid storage bottle 303. The connection between the main liquid storage bottle 303 and the shell 1 and the connection between the auxiliary negative pressure bottle 305 and the shell 1 are all threaded and sealed.

[0025] See also Figure 2 and Figure 5 The main liquid storage bottle 303 is connected to the inner cavity of the collection chamber 13, and the bottoms of the main liquid storage bottle 303 and the auxiliary negative pressure bottle 305 are both connected with valves 302. An elbow 304 is installed between two adjacent valves 302 and connected by the elbow 304. By setting the valve 302 and the elbow 304, the space inside the main liquid storage bottle 303 and the auxiliary negative pressure bottle 305 can be connected when the valve 302 is opened; Under the premise that the transmission tube 10 is connected to the input end of the aspirator 7, the length of the transmission tube 10 is not limited; In actual application, a bracket is fixedly connected to the top of the shell 1, and the bracket is used to meet the stable installation requirements of the second motor 901.

[0026] A closed chest drainage device with an automatic alarm function comprises the following steps: A: Pre-debugging preparation, set the detection distance value of the liquid level sensor 301, set the interval working time and continuous working time of the first motor 205, set the monitoring distance of the distance sensor 907 according to the negative pressure demand, the water seal chamber 15 and the regulating chamber 8 are both pre-filled with water, and the water level in the regulating chamber 8 is higher than the water level in the water seal chamber 15, the main liquid storage bottle 303 and the auxiliary negative pressure bottle 305 are both in the installed state, and the valve 302 is in the closed state; B: Adjustment of negative pressure intensity. According to the actual negative pressure intensity requirement, the height of the bottom end of the hollow screw 903 needs to be adjusted to adjust the position of the hollow screw 903 in the water of the adjustment chamber 8. First, the second motor 901 is controlled to work and the driving gear 902 rotates. Under the meshing transmission of the ring gear 905, the screw sleeve 904 can rotate. Under the threaded transmission of the hollow screw 903 and the positioning and guiding action of the connecting frame 906, according to the rotation direction of the screw sleeve 904, the hollow screw 903 can be flexibly moved up and down. The distance sensor 907 detects the distance between the housing 1 and transmits the signal to the time controller 5, which is displayed on the display screen 4, so that the medical staff can adjust the hollow screw 903 to a suitable height. C: Negative pressure drainage treatment, firstly, the drainage tube 204 is separated from the anti-slip groove 203, and according to actual needs, the drainage tube 204 is moved out of the empty groove 202 at a suitable position to ensure that the drainage tube 204 can enter the patient's chest cavity well, and then the suction device 7 is controlled to work, and under the cooperation of the transmission tube 10 to guide the air, the inner cavity of the regulating cavity 8 is in a negative pressure state, and the effusion in the patient's chest cavity will be transmitted to the collection cavity 13 by the drainage tube 204 and the infusion tube 14, wherein the liquid is collected by the main liquid storage bottle 303 due to gravity falling, and the gas is transmitted to the water in the water seal cavity 15 by the guide tube 12, and then enters the regulating cavity 8 through the air transmission tube 11, and is sucked out by the suction device 7; D: Anti-blocking protection. In order to effectively reduce the probability of blockage of the drainage tube 204, the first motor 205 is controlled to work at a fixed time to drive the rotating rod 209 and the movable frame 208 to rotate, so that the revolving squeezing wheel 207 contacts and squeezes the drainage tube 204 at intervals. The squeezing wheel 207 also rotates by itself, thereby squeezing the drainage tube 204, which can effectively avoid blood clot blockage; E: Uninterrupted liquid collection. As the drainage time goes by, the liquid in the main liquid storage bottle 303 gradually increases. At this time, the liquid level sensor 301 detects that the liquid level in the main liquid storage bottle 303 reaches the preset value. The liquid level sensor 301 sends a signal to the time controller 5. The time controller 5 automatically controls the alarm 6 to sound, reminding the medical staff to reduce the liquid level in the main liquid storage bottle 303 in time. It only needs to control the valve 302 to open. Since the auxiliary negative pressure bottle 305 is in a negative pressure state, the liquid in the main liquid storage bottle 303 will naturally enter the auxiliary negative pressure bottle 305 through the curved pipe 304, which can effectively reduce the liquid level height in the main liquid storage bottle 303 and will not affect the normal chest drainage. Similarly, the medical staff only needs to regularly disassemble and replace the auxiliary negative pressure bottle 305 without disassembling the main liquid storage bottle 303, which can ensure the uninterrupted closed chest drainage operation, which is more in line with actual use needs.

[0027] To sum up: the closed chest drainage device with automatic alarm function, by providing a lead anti-blocking component 2 and an uninterrupted liquid storage component 3, solves the problem that basic drainage devices often do not have the function of wiring anti-blocking. During the drainage of effusion, manual and timed squeezing of the pipeline is required to ensure patency, which not only increases the labor intensity, but also is prone to manual time errors. It also cannot automatically warn and cannot promptly remind of a full container.
