Example one
Fig. 1 is a flowchart of a simulation identification method for an electrocardiograph lead according to an embodiment of the present invention, where the method is applicable to a case where simulation is performed on an electrocardiograph lead position correctly, and the method may be executed by a controller or a control system. As shown in fig. 1, the method for analog identification of an electrocardiographic lead according to the present embodiment specifically includes the following steps:
step S110, acquiring a first signal emitted by placing at least one group of first leads at a first position of the human body model through a preset sensor.
Specifically, the preset sensor of this embodiment may be a hall sensor, and the first lead refers to a lead electrode, and a magnet may be embedded in the lead. The appearance of each lead can have different colors, and due to the different magnetic sizes of the magnets arranged inside, the magnetic fields sensed by the preset sensors (in this embodiment, the hall sensors) in the human body model are also different, and the output first signals (in this embodiment, the first signals can be hall signals) are also different. After the preset sensor generates the first signal, the control system may receive the first signal sent by the preset sensor. The first lead of the present embodiment may be multiple, and may refer to all leads placed by the operator at the position of the manikin where the electrocardiographic lead simulation recognition is needed. In this embodiment, a method of placing the magnet in the human body model and placing the hall sensor in the lead may also be adopted, as long as it is ensured that the magnet and the hall sensor are used in cooperation for determining whether the lead at some positions of the human body model is correctly placed, and no more limitation is made here. In this embodiment, the conducting state of the lead can be realized by placing the reed switch and the magnet in the human body model and the lead respectively (which is placed in the human body model or the lead is not specifically limited as long as the magnets can be used in a matching way, and the magnetic field intensity of each magnet is different), thereby realizing the conducting state of the lead by the magnets with different magnetic field intensities or different induction distances. When the lead is turned on, it indicates that the lead at the placement position is correctly placed.
And S120, comparing a preset second signal with the first signal to judge whether the first lead is correctly placed, wherein the preset second signal is a signal emitted by at least one group of second leads placed at a second position of the human body model.
Specifically, in this embodiment, the preset second signal refers to a signal obtained by a preset sensor of the human body model when the correct lead (i.e. the second lead of this embodiment) is placed at the correct position of the human body model (i.e. the second position of this embodiment). Each preset second signal corresponds to the first signal of the first lead placed at the same position. After the preset sensor of the human body model acquires the first signal of the first lead placed on the first position, the control system can compare or match the preset second signal of the position close to or matched with the first position (namely, the second position of the embodiment) with the first signal, so as to judge whether the first lead is placed correctly according to the comparison result. When the comparison result is that the matching is the same, it means that the first lead and the second lead are the same lead electrode, and the position where the first lead is placed (i.e. the first position) is the same as the position where the second lead is placed (i.e. the second position), that is, the first lead is placed at the correct position. When the comparison result shows that the matching is not the same, the result shows that at least one of the two situations that the first lead and the second lead are different and the position of the first lead (namely, the first position) and the position of the second lead (namely, the second position) are different exists, namely, the first lead is placed at the wrong position or deviates from the correct position.
The first embodiment of the invention has the beneficial effects that the preset sensors are used for sensing the sensing elements at different placing positions and generating different sensing signals, so that the technical problem that whether the leads are placed correctly when an operator conducts electrocardio leads cannot be intelligently judged in the prior art is solved, and the technical effect of intelligently judging whether the electrocardio lead simulation of the operator is correct is realized.
Example two
The second embodiment of the invention is further improved on the basis of the first embodiment. Fig. 2 is a flowchart of a simulation identification method for an electrocardiographic lead according to a second embodiment of the present invention. As shown in fig. 2, the analog identification method for cardiac leads of this embodiment includes:
step S210, acquiring at least one group of preset second signals emitted by placing second leads at a second position of the human body model through a preset sensor or preset software; and storing the preset second signal to a preset database.
Specifically, before the control system acquires the first signal of the first lead, the control system further needs to acquire, through preset software (such as information or signal acquisition software) or preset sensors (such as hall sensors, ultrasonic sensors, infrared sensors, or the like), a signal (i.e., a preset second signal) emitted by a correct lead (i.e., a second lead) at a corresponding position (i.e., a second position) of each human body model to be subjected to analog recognition, and after the preset second signal is acquired, the control system may further store the preset second signal in a corresponding database for storage.
Step S220, acquiring a first signal emitted by at least one group of first leads placed at a first position of the human body model through a preset sensor.
Specifically, in this embodiment, the preset sensor may be a hall sensor, an ultrasonic sensor, or an infrared sensor, or may be other sensors or components (such as a reed switch and a magnet) capable of sensing different signals at different positions, which is not further limited herein. Preferably, the present embodiment takes a hall sensor as an example. The Hall sensor is a magnetic field sensor manufactured according to Hall effect, the first lead refers to a lead electrode, and a magnet can be arranged in the lead. The first lead of the present embodiment may be multiple, that is, all leads placed by the operator at the position of the human body model where the electrocardiographic lead analog identification is required may be referred to. Due to the fact that the magnetic sizes of the built-in magnets are different, magnetic fields sensed by the Hall sensors in the human body model are different, and output first signals (namely Hall signals) are different. After the Hall sensor senses and generates a Hall signal, the control system can receive the Hall signal sent by the Hall sensor. In this embodiment, after the control system obtains the hall signal, the control system may further analyze the hall signal according to a preset signal analysis rule, so as to obtain data (e.g. 1.5, 2, or 3) of the hall signal. For example, when 6 leads are placed on the chest of the manikin, the appearance color of each lead is different, a group of leads and a hall sensor exist at each placement position, when the second position of one lead is located between the fourth rib on the right edge of the sternum, the hall sensor at the second position generates a hall signal corresponding to the group, sends the hall signal to the control system, and then the control system analyzes the hall signal to obtain the analysis data or the image of the hall signal.
Step S230, matching the first signal according to the preset second signal and generating matching information; and judging whether the first leads are correctly placed according to the matching information, wherein the preset second signals are signals emitted by at least one group of second leads placed at a second position of the human body model.
Specifically, in this embodiment, each preset second signal may be analyzed in advance according to a preset analysis rule, so as to obtain analysis data of the corresponding preset second signal, and the first signal is also analyzed, so as to obtain analysis data of the first signal, and the preset second signal and the analysis data of the first signal are compared, or the preset second signal and the first signal are not analyzed, so as to directly compare the preset second signal and the first signal. After the control system obtains the first signal, the control system may compare or match a preset second signal at a position close to or matching the first position (i.e., the second position in this embodiment) with the first signal, so as to determine whether the first lead is correctly placed according to the matching information. In this embodiment, generally, the difference between the first position and the second position is very small, and a maximum error value may be set, so long as the error value between the first position and the second position is less than or equal to the maximum error value, the first position and the second position may be considered to be the same position, that is, the first position matches the second position. Because each first lead is provided with a corresponding Hall sensor induction generated signal, each Hall sensor can be numbered, different transmission channels are adopted for each Hall sensor, the first signals output by each Hall sensor are well transmitted to a control system respectively, and the first signals are matched with the preset second signals corresponding to the transmission channels according to the different transmission channels. The preset second signal of this embodiment may correspond to a numerical range, such as 1 to 2, or 5 to 10, and the specific data range corresponding to the preset second signal may be adjusted by itself according to the factors such as the precision, the cost, and the equipment condition required by the analog recognition, and is not limited herein.
Step S240, if the matching information is that the first signal matches the preset second signal, the first lead is placed correctly; and if the matching information indicates that the first signal does not match the preset second signal, the first lead is placed incorrectly.
Specifically, when the control system matches the first signal with the preset second signal, if the generated matching information indicates that the first signal matches the preset second signal, that is, the first signal is located within the data range of the preset second signal, it indicates that the first lead is correctly placed. For example, if the first signal is 1.5, when the predetermined second signal is 1 to 2, which means the first signal is within the data range of the predetermined second signal, the first signal can match the predetermined second signal, i.e. the first lead is correctly placed. If the generated matching information indicates that the first signal does not match the preset second signal, that is, the first signal exceeds the data range of the preset second signal, the first lead is placed incorrectly. For example, if the first signal is 2.3, when the predetermined second signal is 4 to 6, which means that the first signal is not in the data range of the predetermined second signal, the first signal cannot match the predetermined second signal, i.e. the first lead is placed incorrectly. In this embodiment, when the first lead is misplaced, the control system may also feed back the misplaced information of the first lead to the operator to inform the operator which lead was misplaced.
And S250, if the matching information indicates that the first signal does not match the preset second signal, feeding back information of wrong placement of the first lead to an operator.
Specifically, after the first lead is placed incorrectly, the control system can feed back the information of the first lead placement to the operator to inform the operator of which lead placement is wrong, so as to achieve the effect of intelligently correcting the electrocardio lead placement.
The second embodiment of the invention has the advantages that the preset sensor is used for sensing the sensing elements at different placement positions and generating different sensing signals, thereby solving the technical problem that whether the leads are placed correctly when an operator conducts the electrocardio leads in the prior art can not be intelligently judged, and realizing the technical effects of intelligently judging whether the electrocardio leads of the operator are simulated correctly, highly restoring an operation simulation scene and improving the teaching efficiency.
