[0033] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the air chamber module 2 includes a cover 24 and a solenoid valve 25. The air chamber air inlet 21 and the air bag inflation port 22 are both arranged on the cover 24. The cover 24 is installed on the solenoid valve 25. The air chamber air inlet 21 is communicated with the solenoid valve 25 and inflates the solenoid valve 25 through the air chamber air inlet 21. Exemplarily, the air chamber air inlet 21 is arranged on the cover 24. A passage penetrating through both ends of the air chamber air inlet 21 and the solenoid valve 25 is arranged in the inside of the cover 24. The air chamber air inlet 21 is communicated with the solenoid valve 25 through the passage. The solenoid valve 25 in the air chamber module 2 can be one or more.

The air bag module 3 can also deflate the solenoid valve 25 through the air bag inflation port 22.

[0034] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the solenoid valve 25 is provided with a solenoid valve air inlet 251, and the solenoid valve air inlet 251 is respectively communicated with the air bag inflation port 22 and the air chamber air inlet 21. Each solenoid valve 25 includes a corresponding solenoid valve air inlet 251. The solenoid valve 25 is communicated with the air chamber air inlet 21 and the air bag inflation port 22 through the solenoid valve air inlet 251. When the solenoid valve air inlet 251 is blocked, the air chamber air inlet 21 is not communicated with the solenoid valve air inlet 251, and the air bag inflation port 22 is communicated with the inside of the solenoid valve 25. Through the above structure of the solenoid valve 25, the inflation of the air bag module 3 can be realized, and the passage for the air bag module 3 to deflate the solenoid valve 25 can be provided.

[0035] In some embodiments, referring to Figure 1 , Figure 2 , Figure 3 andFigure 4 The electromagnetic valve 25 is further provided with an electromagnetic valve air outlet 252, which is in communication with the air bag air inlet 31. Thus, a gas discharge path is formed, in which the air bag module 3 is sequentially connected to the air bag air inlet 22, the electromagnetic valve air inlet 251 and the electromagnetic valve air outlet 252, and the gas in the air bag module 3 is discharged from the electromagnetic valve 25.

[0036] In some embodiments, referring to Figure 1 , Figure 4 , Figure 5 and Figure 6 , the electromagnetic valve 25 is internally provided with a moving part 253. The moving part 253 is configured to move towards the electromagnetic valve air outlet 252 and block the electromagnetic valve air outlet 252 in the energized state, and move towards the electromagnetic valve air inlet 251 and block the electromagnetic valve air inlet 251 in the de-energized state. By providing the moving part 253 inside the electromagnetic valve 25, when the air pump 4 inflates the air bag module 3, the moving part 253 is energized and moves towards the electromagnetic valve air outlet 252 and blocks the electromagnetic valve air outlet 252, thereby forming a gas containing space connected to the air chamber air inlet 21, the electromagnetic valve air inlet 251, the electromagnetic valve 25, the air bag air inlet 22 and the air bag module 3, i.e. a path for inflating the air bag module 3. When it is necessary to discharge the gas in the air bag module 3, the connecting part in the electromagnetic valve 25 is de-energized, and in the de-energized state, the moving part 253 moves from the electromagnetic valve air outlet 252 to the electromagnetic valve air inlet 251 and blocks the electromagnetic valve air inlet 251. At this time, a path is formed in the air chamber module 2, which is connected to the air bag air inlet 22, the electromagnetic valve 25 and the electromagnetic valve air outlet 252, and the gas in the air bag module 3 can be discharged through the path via the electromagnetic valve air outlet 252.

[0037] In some embodiments, referring to Figure 1 , Figure 3 and Figure 4 , the cover 24 includes an upper cover 241 and a lower cover 242, and the upper cover 241 is connected to and in communication with the lower cover 242. The air chamber air inlet 21 is formed on the upper cover 241, and the air bag air inlet 22 is formed on the lower cover 242. The lower cover 242 can be configured as a cavity including multiple openings, which can become a transfer space connected to the air chamber air inlet 21, the air bag module 3 and the electromagnetic valve 25, for example, the lower cover 242 can be in communication with the air chamber air inlet 21, the air bag air inlet 22 and the electromagnetic valve 25 through the openings. The electromagnetic valve air inlet 251 can be arranged inside the lower cover 242 close to one side of the upper cover 241, so that when the electromagnetic valve air inlet 251 is blocked by the moving part 253, the electromagnetic valve 25 can be in communication with the air bag module 3 through the air bag air inlet 22, thereby achieving the discharge of the air bag module 3 through the electromagnetic valve air outlet 252.

[0038] In some embodiments, referring to Figure 1 and Figure 3 , a second sealing member 243 is further arranged between the upper cover 241 and the lower cover 242, and the second sealing member 243 is used to realize the sealing of the connection between the upper cover 241 and the lower cover 242. Thus, the gas leakage from the joint between the upper cover 241 and the lower cover 242 when the air pump 4 inflates the air bag module 3 can be prevented, so as to ensure the efficiency of the air bag module 3 inflation. At least one set of through holes is arranged in the interior of the upper cover 241, the second sealing member 243 and the lower cover 242, the through holes in each set are positionally corresponding and identically sized, and are in communication with each other to form a channel; the through holes in different sets are spaced from each other, that is, the channels are spaced from each other. Exemplarily, three sets of through holes, that is, three channels, can be arranged in the interior of the upper cover 241, the second sealing member 243 and the lower cover 242, and the two ends of each channel are in communication with the electromagnetic valve 25 and the air chamber air inlet 21, respectively.

[0039] In some embodiments, referring to Figure 1 , Figure 3 and Figure 5 , a sensor 26 can be arranged at the air chamber air inlet 21, and the sensor 26 is in communication with the air chamber air inlet 21. The sensor 26 and the air chamber air inlet 21 have a connecting passage therebetween, and the sensor 26 can be a pressure sensor 26. Thus, the real-time air pressure in the interior of the air chamber module 2 can be detected or monitored through the above-mentioned passage, so as to ensure the normal operation of the thrombus pump, and the air pressure in the air bag module 3 can be confirmed to reach the working air pressure or the air in the air bag module 3 can be confirmed to be completely discharged.

[0040] In some embodiments, the main body part 1 is configured with a containing cavity, and the air chamber module 2 is detachably installed in the containing cavity. Through the modular design of the whole thrombus pump, the air pump 4 and the air chamber module 2 can be modularly and detachably installed in the interior of the containing cavity, so as to facilitate the disassembly or maintenance of the air pump 4 or the air chamber module 2. The air bag module 3 is detachably connected with the air bag module 3 through the air bag air inlet 31, for example, the two ends of the first sealing member 23 are connected with the air bag inflation port 22 and the air bag air inlet 31, respectively, and the connection position must be completely sealed after the connection is completed. Therefore, the air bag inflation port 22 and the air bag air inlet 31 can be surrounded by an extension, the extension can be tubular, and the two ends of the first sealing member 23 can be sleeved on the outer periphery of the extension of the air bag air inlet 31 and the air bag inflation port 22 and are in interference fit with the two extensions; or the two ends of the first sealing member 23 can be inserted into the interiors of the two extensions.

[0041] Further, in order to make the connection between the air bag module 3 and the air chamber module 2 more reliable, as Figure 2As shown, the fastener 33 can be arranged on the air bag module 3, and the connection between the air bag module 3 and the air chamber module 2 is strengthened by the fastener 33 when the first seal 23 is connected to the air bag module 3, so that the separation of the air bag module 3 and the air chamber module 2 due to inflation or deflation of the air bag module 3 during use of the thrombus pump is prevented.

[0042] To further strengthen the connection strength between the air chamber module 2 and the air bag module 3, an air bag connecting plate 32 can be additionally arranged between the air chamber module 2 and the air bag module 3. The air bag connecting plate 32 can be fixed to the outer wall of the air bag module 3 by adhesion or the like, and then the air bag connecting plate 32 is fixedly connected to the air chamber module 2 or the main body part 1 by the fastener 33, so as to strengthen the connection between the air chamber module 2 and the air bag module 3. The air bag connecting plate 32 can be a hard plate, for example, a steel plate, so that the air bag module 3 can remain undeformed during inflation or deflation, thereby not affecting the connection between the first seal 23 and the air bag inlet 31.

[0043] In some embodiments, referring to Figure 1 , the air chamber module 2 can be detachably mounted on the main body part 1. The main body part 1 can be provided with a first connecting piece 11, and the air chamber module 2 can be provided with a second connecting piece 27 corresponding to the position of the first connecting piece 11.

The first connecting piece 11 and the second connecting piece 27 can be snap connection, threaded connection or magnetic connection. Exemplarily, the first connecting piece 11 and the second connecting piece 27 can be a clamping groove and a clamping buckle respectively.

[0044] The above is only a preferred embodiment of the present application, and is not intended to limit the present application.
