Further, alarm device can also report specific nutrient solution kind when sending the alarm sound, changes suitable nutrient solution with sound prompt nursing staff simultaneously, so, the mode of accessible report nutrient solution kind supplies nursing staff secondary to confirm that the nutrient solution kind of reporting conforms to with predetermined nutrient solution kind. In other embodiments of the present invention, a manner of sounding an alarm and/or prompting the caregiver to change the appropriate nutrient solution by sound and displaying the type of the nutrient solution by a display screen may also be employed to allow the caregiver to secondarily confirm whether the type of the infused nutrient solution matches the preset type of nutrient solution. It should be noted that the specific structure of the conductivity tester, and the specific software and hardware structure and processing module program related to the alarm of the command alarm device, which are designed by those skilled in the relevant art according to the prior art, are electrically connected to the processing module through the conductivity tester, and therefore the problem of insufficient disclosure of the present invention will not occur if the detailed description is omitted.
During detection, if the detected conductivity falls into the preset conductivity range, the processing module determines that the nutrient solution (such as enteral nutrient solution) provided by the liquid supply part 1 conforms to the type of the preset nutrient solution (such as intravenous nutrition), at the moment, the processing module sends a passing signal to the alarm device, so that the alarm device prompts the correct type of the nutrient solution through prompting sound (such as cheering sound), infusion operation can be carried out, or the correct type of the nutrient solution is broadcasted through sound, the infusion operation can be carried out, and the nutrient solution type can be broadcasted through sound or displayed through a display screen at the same time, so that a caregiver can secondarily confirm the type of the nutrient solution.

It should be noted that, in other embodiments of the present invention, the type of the nutrient solution to be infused may be adjusted at the detection device 3, in which case, the detection device 3 may be provided with an adjustment button and a display screen, which is convenient for the caregiver to adjust the type of the nutrient solution to be infused, and of course, the detection device 3 may also be provided with no adjustment button and no display screen, and the type of the nutrient solution to be infused is adjusted at the external control device by means of an external control device. In the embodiment that the type of the pre-transfusion nutrient solution can be adjusted, the second pipeline II may not be configured with the auxiliary judgment manner described in this paragraph.
Furthermore, in order to prevent the nutrient solution in the liquid storage part 25 from flowing back to the liquid supply part 1 after the detection is finished, a blocker 24 is further arranged between the end part of the detection tube 23, which is communicated with the liquid supply part 1, and the liquid storage part 25 (namely, the upstream of the liquid storage part 25), the blocker 24 has a structure similar to that of the infusion speed regulator 22, and also comprises a connecting frame arranged on the detection tube 23 and a flow rate regulating wheel arranged on the connecting frame, and the flow rate regulating wheel is pushed to the corresponding end part of the connecting frame, so that the nutrient solution in the detection tube 23 can be blocked from flowing, and the nutrient solution in the liquid storage part 25 can be prevented from flowing back.
