Detailed Description

The following examples are given for the purpose of illustration only and are not to be construed as limiting the utility model, including the drawings for reference and description only, and are not to be construed as limiting the scope of the utility model as many variations thereof are possible without departing from the spirit and scope of the utility model.

Referring to fig. 1, an embodiment of the present utility model provides a system block diagram of a shunt collection device for serial communication, the device is applied to an anesthetic agent or a monitor, the device includes a device main body 10, in which a processor and a voltage conversion unit, which are connected to each other, are integrally disposed, and the voltage conversion unit is connected to at least one data collection connector 20 and a plurality of data output connectors 30. The structural schematic diagram of the shunt acquisition device for serial port communication provided by the embodiment of the utility model is shown in fig. 2.

In the implementation, the data acquisition connector 2 is connected with an anesthesia machine or a monitor, and the processor in the device main body 1 sends various request commands to the anesthesia machine or the monitor through the data acquisition connector 2, and if the communication is unsuccessful, the request commands are continuously sent after a delay of 10 seconds. Until the communication is successful, the processor receives the data from the anesthesia machine or the monitor and sends the data to the data output connectors 3 and 4.

It should be noted that, because there are a plurality of different types, brands of anesthesia machines and monitors, and the request commands are different, sending different request commands can satisfy the use requirements of more medical scenes as much as possible. Setting a delay of 10 seconds for the send command avoids sending too many useless request commands when the communication fails.
