The skin current sensor, GSR, is an abbreviation of GalvanicSkinResponse, and when human emotion or state changes, the skin changes differently, the most significant point of the change is that sweat on the skin increases, so that the conductivity of the skin increases, and such characteristics can be utilized to realize the function of human-computer interaction. Galvanic skin responses may be acquired by a skin current sensor. In the case of blood transfusion, when the transfusion reaction occurs, the skin is caused to change differently, and this principle is used for alarming in the following examples.
In this embodiment, a method for alarming during blood transfusion is provided, and fig. 1 is a flow chart of the method for alarming during blood transfusion according to the embodiment of the present application, as shown in fig. 1, the flow chart includes the following steps:

step S104, the skin current sensor sends the parameter information of the skin current change to a gateway, wherein the skin current sensor is wirelessly connected with the gateway;
step S106, the gateway sends the parameter information of the skin current change to a server, wherein the server stores the parameter information of the skin current change of the patient in each period;
step S108, the server generates a first curve according to the received skin current change of the period;
step S110, the server compares the first curve with the plurality of historical curves one by one, and when the difference between the first curve and the historical curves reaches a preset range, the value of N is added with 1, wherein the initial value of N is 0, and N is a positive integer; the historical curve is a curve generated by parameters of skin current changes in other periods before the period;
as an optional implementation, the server comparing the first curve with the historical curve includes: the server trains to obtain a first model, wherein the first model is a neural network model, the neural network model is obtained by performing machine learning training on a plurality of groups of training data, each group of training data in the plurality of groups of training data comprises input data used for training and output data used for training, the input data used for training is two curves, the output data used for training is a numerical value, the numerical value is used for representing the similarity degree of the two curves used as the input data used for training, and the numerical value used as the output data used for training in each group of training data represents the similarity degree of the two curves used as the input data used for training; the server inputs the first curve and a historical curve into a first model, and first output data are obtained from the first model, wherein the first output data are numerical values used for representing the similarity degree of the first curve and the input historical curve; and the server judges whether the numerical value in the first output data is in the preset range, and if the numerical value is not in the preset range, the N value is added with 1.
As another optional embodiment, the server comparing the first curve with the historical curve includes: the server places the first curve and a historical curve in the same coordinate system; the server selects 100 points with the same abscissa from the first curve and the historical curve, wherein the 100 points are uniformly distributed on the first curve and the historical curve; the server judges whether the difference of the longitudinal coordinates of the 100 points on the respective curves is within a preset range, and if the difference of the longitudinal coordinates corresponding to the respective curves is larger than the preset range, the server determines that the points of which the difference of the longitudinal coordinates corresponding to the respective curves is larger than the preset range are difference points; and the server acquires the number of the difference points, and if the number of the difference points exceeds the preset range, the N value is added with 1.
As an alternative, it may be added that the cycle is two minutes, i.e. one curve is saved for each two minutes, the current two minute curve is compared with the previous historical multiple two minute curves, and if there is a significant change, it indicates that the patient's state has changed. To make the comparison quicker, it is more obvious to compare the curves of the first four two minutes of the current cycle, i.e. the change of state within the last ten minutes. The data of two minutes of the current period and the data of the previous four minutes and two minutes are stored in the memory of the server, so that the calculation speed is increased by using the data in the memory for calculation.
As another alternative, the skin current sensor and the gateway are connected through a bluetooth connection or a wireless local area network.
