The second side plate 150 is fixed to the main bracket 112 and covers the third opening 1203 so that the second side plate 150 forms the third appearance surface 180 of the medical device 10.

[0052] Further, the second side plate 150 can be fixed to both the main bracket 112 and the housing 120 simultaneously. In some other embodiments, the second side plate 150 can be fixed only to the main bracket 112 or the second side plate 150 can be fixed only to the housing 120.

[0053] Specifically, the second side plate 150 can be a communication interface panel. A communication interface board 1194 can be fixed to the side of the main bracket 112 facing away from the first side plate 113. The communication interface panel shields the communication interface board and serves as the appearance surface of the medical device 10. A plurality of through holes are usually provided on the communication interface panel to expose the communication interfaces provided on the communication interface board 1194. The communication interface board 1194 provides communication interfaces for communicating with other medical devices 10 or a plug-in monitor host. A power interface can be provided on the communication interface board 1194. When the medical device 10 is installed on the plug-in monitor host, it can not only communicate with the plug-in monitor host but also charge the medical device 10.

[0054] Specifically, the communication interface board 1194 can be a Pogopin interface board.

The convex wall 11231 and the protrusion 1113 are connected by a first fastener 1124 inserted into the first opening 11203 and the second opening 11101. The orientation of the first opening 11203 is parallel to the plane where the screen 1111 is located. The first fastener 1124 passes through the first opening 11203 and the second opening 11101 along the direction parallel to the plane where the screen 1111 is located to fix the display screen assembly 111 on the main bracket 112 in the direction parallel to the plane where the screen 1111 is located. In this application, the display screen assembly 111 is fixed on the screen bracket 1112. On the one hand, after the functional module 110 is inserted into the installation cavity 1204, the first fastener 1124 is hidden, making the first appearance surface 160 and the overall appearance of the medical device 10 more beautiful. On the other hand, since the housing 120 is provided with a first opening 1201, a second opening 1202, and a third opening 1203, the strength of the housing 120 is relatively small. If the display screen assembly 111 is only mounted on the housing 120, the housing 120 cannot provide good support for the display screen assembly 111. Among them, the first fastener 1124 can be a screw.

[0058] Further, the orientation of the first opening 11203 can be parallel to the plane where the screen 1111 is located. The first fastener 1124 passes through the first opening 11203 and the second opening 11101 to fix the display screen assembly 111 on the main bracket 112 in the direction parallel to the screen 1111.

[0059] In some other embodiments, the orientation of the first opening 11203 may not be parallel to the plane where the screen 1111 is located, and the orientation of the first opening 11203 may be perpendicular to the plane where the screen 1111 is located. The first fastener 1124 fixes the display screen assembly 111 on the main bracket 112 along the direction perpendicular to the plane where the screen 1111 is located. The display screen assembly 111 can also be connected to the main bracket 112 and the housing 120 at the same time, further improving the connection stability.

There are many components in the medical device 10. To ensure the stability of the structure, the requirements for the layout of each component are relatively high. If the housing 120 is relatively small, while the requirements for the layout are higher, there are also requirements for the heat dissipation effect. Stacking components that generate more heat together is not conducive to the heat dissipation inside the medical device 10, and may even affect the function of the medical device 10. As much as possible, place the main control board 114 and the battery 190 that generate more heat on both sides of the main bracket 112, and assemble other components outside the housing 120 as much as possible, and then put them into the housing 120 together, which can make the layout of the components more reasonable and simple, conducive to device heat dissipation, and at the same time facilitate the disassembly and replacement of the battery 190.

[0062] Optionally, the main bracket 112 is provided with a partition portion 1128. The battery 190 and the main control board 114 are respectively located on both sides of the partition portion 1128.

By providing the partition portion 1128 and the third mounting groove 11207, the battery 190 and the main control board 114 can be spaced apart, so that the battery 190 and the main control board 114 are separated from each other, improving the heat dissipation effect of the device.

[0063] Specifically, the shape and size of the main control board 114 can be similar to the notch of the third mounting groove 11207. The main control board 114 covers and obscures the third mounting groove 11207, so that the third mounting groove 11207 is not exposed to the outside. The area of the main control board 114 can be greater than or equal to the area of the notch of the third mounting groove 11207.

[0064] Specifically, the shape of the partition part 1128 can be plate-shaped, and the plane where the partition part 1128 is located can be parallel to the plane where the screen 1111 is located. The partition part 1128 can also be a stepped structure composed of two plates, so that the first installation groove 11201 has different depths to install components with different thicknesses together, such as the battery 190 and the carbon dioxide parameter module 192.

[0065] Specifically, the orientation of the third opening 11102 can be perpendicular to the plane where the screen 1111 is located, and the orientation of the third opening 11102 is perpendicular to the orientation of the second opening 11101.
