When the negative pressure output by the suction device, which is combined with the negative pressure machine host composed of the above-mentioned gas circuit assembly and housing assembly, acts on the patient's wound through the end of the first trachea, the end of the second trachea sucks some pus or other impurities from the wound on the patient and transports them into the drainage container.

[0040] The connection relationship of the above gas circuit is as follows: The first gas circuit output port 4002 and the second gas circuit output port 4004 are both arranged on the first mounting side plate 1300. A second-stage gas circuit channel is provided between the first mounting side plate 1300 and the adjacent aspirator 2000. The first gas circuit output port 4002 and the second gas circuit output port 4004 are respectively communicated with the second-stage gas circuit channel, the first-stage gas circuit channel and the second-stage gas circuit channel.

[0041] The above aspirator is assembled with the housing assembly. The gas circuit assembly is communicated at one end of the housing assembly through the two-way first gas circuit output port and the second gas circuit output port inside, and then is communicated with the first trachea through the first-stage gas circuit channel and the second-stage gas circuit channel. The channels of multiple stages are arranged on one side of the aspirator or cooperate with the housing assembly, reducing the complex connection structure of the trachea between the entire negative pressure main unit and the aspirator, and effectively improving the production efficiency of the manufacturer. The pipeline structure of the entire negative pressure machine is more compact, the structure is simple, and the reliability of the entire device is higher.

[0042] Refer to Figures 1 to 2 and Figures 5 to 10 The aspirator 2000 includes a second mounting side plate 2100 installed on the opening on one side of the drainage container 2200. The second mounting side plate 2100 is one of the components detachably connected or connected in the housing assembly. A plurality of protruding bayonets 2110 are provided on the outer side surface of the second mounting side plate 2100. On the outer side surface of the drainage container 2200, a first trachea connection column 2210 and a second trachea connection column 2220 that are concave inward in the direction of the drainage container 2200 are provided. A first trachea channel 2211 is provided in the middle of the first trachea connection column 2210.

[0043] Refer to Figures 1 to 2 and Figures 5 to 10 A plurality of sliding through holes 1310 are provided on the first mounting side plate 1300. A sliding drive plate 1400 is arranged on the inner side surface of the first mounting side plate 1300. The drive plate is one of the components detachably connected or connected in the aspirator. A plurality of sliding blocks 1420 corresponding to the sliding through holes 1310 are provided on the drive plate 1400. As shown in the figure, three sliding blocks 1420 are distributed in a triangular shape on the drive plate 1400, and three sliding through holes 1310 corresponding to the positions of the sliding blocks 1420 are provided on the first mounting side plate 1300.

[0044] Refer to Figures 1 to 2 and Figure 11As shown in the figure, a driving component 3000 is provided at the top of the housing assembly 1000. The driving component 3000 includes a pressing mechanism 3100 and a connecting plate 3130 installed inside the pressing mechanism 3100 and linked with it. The end of the connecting plate 3130 is connected to the driving plate 1400, driving the driving plate 1400 to slide on the inner side surface of the first installation side plate 1300. When the bayonet 2110 passes through the sliding through hole 1310, the sliding block 1420 is engaged and connected with the bayonet 2110; when the bayonet 2110 disengages from the sliding through hole 1310, the sliding block 1420 and the bayonet 2110 are disengaged from each other.

[0045] The second installation side plate on the above-mentioned aspirator, through the bayonet on the second installation side plate, cooperates with the engaging structure of the driving plate on the housing assembly, enabling the aspirator to be removed from the housing assembly or used in combination. The engaging structure between the aspirator and the housing assembly makes the connection between the tracheal channel and the tracheal connection channel tighter, and the airtightness of the aspirator is stronger.

[0046] Refer to Figure 6 、 Figure 7 Combine Figure 12 As shown in the figure, a drainage installation plate 2300 is further provided inside the drainage container 2200.

[0047] The above-mentioned first-stage gas path channel is a rigid pipeline through the combination of the first pipeline installation column and the first tracheal channel. The airtightness of the first-stage gas path channel is good and it directly acts on the outside of the aspirator. Even if the aspirator is removed and separated multiple times, the first-stage gas path channel can still maintain good airtight performance.

[0048] Refer to Figure 9 And Figure 12, on the side of the second mounting side plate 2100, there is a first support rib 2130, and on the side of the drainage mounting plate 2300, there is a second support rib 2320.

Due to the negative pressure environment inside the above-mentioned second-stage gas path channel and the normal atmospheric pressure outside the negative pressure machine, the second support rib and the first support rib inside the second-stage gas path channel jointly support the second-stage gas path channel. The support effect between the strong support ribs keeps the volume of the second-stage gas path channel inside unchanged, making the negative pressure effect more stable.

[0049] Refer to Figure 5 , on the second mounting side plate 2100, there are a first gas path through hole 2140 and a second gas path through hole 2150.

The interaction between the first reinforcing rib provided on the first gas path through hole and the second support rib prevents the aperture of the first gas path through hole from changing and causing problems with the gas path air pressure.

[0050] In some embodiments, on one inner wall of the first housing 1100, there is a first mounting groove, and on one inner wall of the second housing 1200, there is a second mounting groove. The first mounting side plate 1300 is respectively mounted in a matching manner with the first mounting groove and the second mounting groove. The first housing, the second housing and the first mounting side plate are of a split structure, enabling the first mounting side plate to be replaced, effectively improving the maintenance performance of the equipment.
