Embodiment 1
[0036] Ice water challenge test
[0037] by the anesthetist as figure 1The four monitoring probes 1 are attached to the skin of the target monitoring area (T6, T8, T10, T12) of the surgical patient in sequence from top to bottom. Note: T6, T8, T10, and T12 represent the skin at the 6, 8, 10, and 12 levels of the patient's thoracic vertebrae, respectively.
[0038] When monitoring the plane, the syringe connector is connected to the central interface. As mentioned above, there is half the volume of normal saline in the cavity of the inner and outer walls of the syringe barrel, which has been frozen in advance, and the syringe is equipped with ice water (1) option Access: Turn the pointer 3-1 of the switch to the direction of T12, and the syringe will communicate with the water bag in the T12 area through the T12 channel, but will not communicate with the remaining channels and the water bag (exhaust and sealing the opening of the outer wall will not be described in detail) Pus...
Embodiment 2
[0040] Hot water stimulation test, the specific operation process is as follows:
[0041] As mentioned above, the inner and outer wall cavity of the syringe barrel is vacuum at this time, as in the previous ice water stimulation method, after the syringe draws 10ml of water, the connection part and the monitoring probe sticking part are the same as above, and the anesthetist electrifies the plug, as shown Figure 5 The small light bulb on the right side of the piston is red. After heating for a while, the light on the piston turns green, indicating that the water temperature in the syringe has reached 60°C, and it can be used. This is suitable for anesthesia monitoring of longer-term operations. Since the entire passage has an insulating layer to reduce the temperature loss during the operation, and the thermostat in the piston compensates the temperature of the entire passage, so when this invention is used, it will not follow The prolongation of operation time will affect th...
