The cavity 26 is configured in an open structure at both ends. An inlet 23 of gas is arranged at one end, the sealing block 22 is used for sealing, an outlet 24 of gas is arranged at one end, and the pressure sensor 25 is connected in a threaded manner. The pressure sensor 25 is connected to the control unit in a wired manner, and in this embodiment, the control unit is configured as a single-chip microcomputer and a battery. The singlechip is a main control unit of the simulated blood gas analyzer and is used for receiving signals sent by the pressure sensor and sending printing commands to the printing unit. The battery provides power support for the simulated blood gas analyzer.
Specifically, in order to make the sealing block and the connecting piece be more stably fixed to the fixing base, a groove structure is provided inside the fixing base, which is a groove one 212 and a groove two 213 (as shown in fig. 3), where the groove one 212 is correspondingly provided with the sealing block 22, and is used for clamping and fixing the sealing block 22. The second groove 213 is used for clamping the connecting piece 27, so that the connecting piece 27 is fixed in the fixing seat 21. The fixing base is also provided with a through hole 211 so that the sampling needle 5 can reach the sealing block 22 through the through hole.
In this embodiment, the sealing block is made of silicone rubber. By using the silicon rubber material as the sealing block of the device, the tightness of the sealing block in connection with the cavity inlet can be well ensured, and when the blood gas analysis is performed once, the sampling needle penetrates through the sealing block to inflate the cavity, and the needle eye reserved by the sampling needle can be quickly recovered, so that the next use is not influenced. Namely, the sealing block made of the silicone rubber material can be used for sealing after multiple sampling needle punctures. The replacement of the consumable of the simulated blood gas analyzer is reduced, and the use cost is reduced.
