Description
Technical Field

Background
Sudden cardiac death is mainly caused by ventricular fibrillation VF and ventricular velocity VT. VF/VT attacks often have no warning sign, the electrical activity of the ventricles is out of synchronism during the attack, the heart pumping function is lost, and if measures are not taken in time to transfer the heart rhythm, the patient can die within minutes. Electrical defibrillation by a defibrillator is an effective means of dealing with VF and VT.
The defibrillator is complex in operation, defibrillation operation training needs to be widely carried out in order to master defibrillation operation, the conventional training and learning process is only carried out through demonstration videos or field demonstration, the training process of watching the demonstration videos lacks interactivity, and only knowledge is transmitted in a single direction; the on-site demonstration cannot guide all students one by one. Therefore, the existing defibrillator training process is poor in interactivity and low in training efficiency.
In addition, there is a dedicated analog defibrillator in the prior art, which does not generate electric shock energy during the analog training process, although the safety is improved, the use experience is far away from that of a real defibrillator, and the analog simulation degree is poor, so that the real defibrillator cannot be used qualified, and a good training effect cannot be achieved.
In addition, in the practical application of the defibrillator, the parameters of the defibrillator are usually set according to the personal condition of the rescued person, such as the size of the selected electrode and the defibrillation energy, but the simulation person of the existing simulation training system is simple and cannot simulate different rescued persons.
In addition, if a real defibrillator is used for training operation, firstly, safety problems exist, secondly, a guiding and prompting function is lacked, and an evaluating and feedback function is lacked, so that a student is difficult to know standard operation specifications and know whether the standard operation is standard and which links are wrong. The defibrillation operation involves a plurality of key steps, such as the selection of defibrillation electrodes, the selection of defibrillation energy, and the selection of defibrillation electrode positions, and how to evaluate and guide the operation of each step is a problem to be solved urgently.

step 3.1, when the simulation personnel places the defibrillation electrode on the simulation human model in the defibrillation operation; an RF reading device in the simulated human model reads an RF tag of the defibrillation electrode, obtains a unique identification code of the current electrode, and sends the unique identification code to a processing module of the simulated human model;
3.2, the processing module of the simulated human model obtains the size of the defibrillation electrode according to the mapping table of the unique identification code and the size of the electrode, and sends the size of the defibrillation electrode to the evaluation module of the monitoring host;
3.3, judging whether the size of the defibrillation electrode is matched with the simulation item set in the step 1 by an evaluation module in the monitoring host, if so, judging that a simulation worker selects the correct electrode size, entering the step 4, otherwise, judging that the simulation worker selects the wrong electrode size, and sending out a warning and displaying wrong operation content by a warning module of the monitoring host;
the infant uses the defibrillation electrode with a smaller size, and the adult uses the defibrillation electrode with a larger size;
step 4, judging whether the simulation personnel selects correct defibrillation energy, comprising the following steps:
step 4.1, after the simulation personnel place the defibrillation electrode on the simulation human model, selecting an electric shock energy gear on the defibrillator, and sending an energy gear signal to the monitoring host by the defibrillator;
step 4.2, an evaluation module in the monitoring host machine judges whether the currently selected electric shock energy gear is matched with the simulation project set in the step 1, if so, the simulation worker is judged to select correct defibrillation energy, the step 5 is entered, if not, the simulation worker is judged to select wrong defibrillation energy, and an alarm module of the monitoring host machine gives an alarm and displays wrong operation content;
infants use lower defibrillation energy, adults use higher defibrillation energy;
step 5, judging whether the position of the defibrillation electrode placed by the simulation personnel is correct or not, comprising the following steps:
step 5.1, the simulation personnel places the defibrillation electrode at the defibrillation position which is considered to be correct by the simulation personnel and applies certain pressure;
step 5.2, when the cells in the standard defibrillation position area are contacted with the defibrillation electrode, the pressure sensing device generates a trigger signal and sends the trigger signal to a processing module in the simulated human model; each pressure sensing device senses the current pressure value and sends the current pressure value to a processing module in the simulated human model;
step 5.3 the processing module in the simulated human model counts the number of the trigger signals and calculates the contact area S1
S1＝k*w，
Wherein k is the number of trigger signals and w is the area of each cell; the processing module calculates an average pressure value F1
Wherein fi is a pressure value sensed by the ith pressure sensing device;
step 5.4 processing Module will S1And F1The value of (A) is sent to a monitoring host, and an evaluation module in the monitoring host calculates a position index parameter C

in the prior art, when the accurate placement position needs to be judged, the judgment is usually carried out by considering the area of the overlapping position with the standard region position, but the placement position of the defibrillation electrode has specificity, and the judgment accuracy is lower only by calculating the overlapping area. Because the human body is not a horizontal plane but has the height and the undulation, but the defibrillation electrodes of the professional defibrillator used by medical staff are in a plane structure, the size of the contact area is closely related to the degree of coincidence of the defibrillation electrodes and the standard area position and the pressing force. For example, when the defibrillation electrodes deviate from the standard zone location, the contact area may be less than the standard threshold, where placement position errors should be detectable; however, if the pressing force of the simulator is much higher than the standard force, the contact area increases, and even meets the requirement of the standard threshold, and at this time, the problem of preventing the position error cannot be detected according to the size of the contact area.
According to the method and the device, the contact area is corrected according to the pressure degree, so that accurate position index parameters are obtained, and whether the defibrillation electrode is placed at the position of the standard area or not can be accurately judged.
For example, if the degree of pressing F1Is a standard value F0Then, the calculated position index parameter C is S1-α|F1-F0|＝S1At this time, since the degree of pressing force is a standard value, the position of the defibrillation electrode can be determined by considering only the contact area, if S1If the preset threshold value is larger than the preset threshold value, judging that the placement position of the defibrillation electrode is correct, otherwise, judging that the placement position of the defibrillation electrode is correctIncorrect positioning;
if degree of pressing F10, i.e. no pressure is applied, at which time the pressure sensing device should have no trigger signal and no pressure value, so S1If 0, the position index parameter C is calculated to S1-α|F1-F0If the requirement for the preset threshold is clearly not met, this indicates that the defibrillation electrode placement is incorrect.
Step 6, judging whether the simulation personnel correctly deal with the heart rhythm change, comprising the following steps:
step 6.1, sending the real defibrillation-impossible heart rhythm data of the patient stored in the database in the monitoring host computer to the simulated human model, wherein a heart rhythm simulation module of the simulated human model generates a second heart rhythm signal corresponding to the real defibrillation-impossible heart rhythm data;
