Embodiment 1

[0038] like figure 1 As shown, the intelligent liquid drainer for infusion disclosed in this embodiment includes a main circuit switch assembly 1, at least one branch circuit switch assembly 2 and a control circuit board 13, such as figure 2 , 3 , 4, the main circuit switch assembly 1 includes a spring clip A9, an electromagnetic lock A5, a manual switch A12, a photoelectric signal generator 7 and a photoelectric signal receiver 8, and the photoelectric signal generator 7 and the photoelectric signal receiver 8 are respectively located on the spring On the two clamp arms of the clamp A9; on the two clamp arms of the spring clamp A9, there are respectively a micro switch A10 and an action lever A11 adapted to the micro switch A10. When the spring clamp A9 is closed, the action lever A11 is pressed on On the micro switch A10, the spring clip A9 is closed under the condition of no external force, the electromagnetic lock A5 includes a deadbolt A6 used to limit the closing of th...

Embodiment 2

[0053] The difference between this embodiment and embodiment 1 is: as Figure 9 As shown, the main circuit switch assembly 1 also includes a tritium lamp 23 and a barcode scanner 26 . Wherein, the voice prompt device includes a speaker 25 , and the power module includes an AAA battery 27 . The barcode scanner 26 is electrically connected with the control circuit board 13 .

[0054] The photoelectric signal generator 7 selects an 850nm near-infrared point laser transmitter, and the photoelectric signal receiver 8 selects a silicon PIN photodiode, whose peak sensitivity wavelength is 850nm. The photoelectric signal receiver 8 is provided with an 850nm infrared filter 24 to filter out light waves in bands other than 850nm.

[0055] The tritium lamp 23 is installed in the casing A, and the casing A is provided with a light-transmitting hole. The tritium lamp 23 does not need a power source and can emit light for 25 years, realizing the auxiliary lighting function of unattended a...

Embodiment 3

[0057] The difference between this embodiment and embodiment 1 or 2 is: as Figure 10 As shown, it also includes a constant temperature vein heating film 28 and a signal acquisition electrode 29, the signal acquisition electrodes 29 are electrically connected with the control circuit board 13, and the signal acquisition electrodes 29 are silver chloride electrodes, which are used to detect the patient's pulse and convulsions. When the pulse changes suddenly and sharply, the alarm will be prompted, for example, when the patient's pulse is lower than 30 beats / min or higher than 100 beats / min, the alarm will be prompted. The constant temperature venous heating film 28 is applied on the infusion tube and the arm. During the infusion process, the cold stimulation caused by the liquid temperature entering the blood vessel is avoided, and the patient's vein is protected. The constant temperature vein heating membrane 28 can be electric heating or "heat stick".
