The invention provides a cardio-pulmonary resuscitation machine and a control method thereof.
The normal starting and use of the existing cardiopulmonary resuscitation machine are roughly divided into two stages, the first stage is a stage in which the cardiopulmonary resuscitation machine wakes up each functional component in response to the triggering of an operator and performs self-checking on each functional component, the second stage is a stage in which the cardiopulmonary resuscitation machine starts pressing in response to the triggering of the operator and acquires working parameters input by medical personnel, and the second stage also needs the operator to place a patient before the pressing is started, and the pressing component is aligned with the chest of the patient and other auxiliary processes. Thus, in situations where a pressing first aid is urgently needed, a great deal of valuable time for rescuing patients is undoubtedly wasted.
To solve the above problem, referring to fig. 1, in an embodiment of the present invention, a method for controlling a cardiopulmonary resuscitation machine includes:
step S100, when the emergency starting signal is received, determining a plurality of preset links required to be executed for normal starting of the cardiopulmonary resuscitation machine and a plurality of working parameters required for normal working of the cardiopulmonary resuscitation machine, and according to the emergency starting signal, determining at least one preset link in the plurality of preset links as a skipped preset link and determining at least one working parameter in the plurality of working parameters as a skipped working parameter;
the cardio-pulmonary resuscitation machine can be provided with an emergency starting switch special for emergency starting so that medical personnel can be triggered according to the emergency degree of an emergency scene, and the triggered emergency starting switch can output an emergency starting signal to the control device of the cardio-pulmonary resuscitation machine so that the control device of the cardio-pulmonary resuscitation machine can determine the triggered function as emergency starting according to the received emergency starting signal and control the cardio-pulmonary resuscitation machine to carry out emergency starting. The control device of the cardiopulmonary resuscitation machine is also a functional component for controlling the normal start of the cardiopulmonary resuscitation machine, wherein a hardware circuit and a software program or algorithm for controlling the normal start of the cardiopulmonary resuscitation machine can be integrated, so that the control device of the cardiopulmonary resuscitation machine can determine a plurality of preset links required to be executed in the first stage and a plurality of working parameters required in the second stage when the cardiopulmonary resuscitation machine is normally started. It should be noted that, a plurality of triggering members may be provided on the emergency starting switch, and each triggering member may enable the emergency starting switch to output an emergency starting signal representing different degrees of urgency when being triggered. The control device of the cardiopulmonary resuscitation machine can analyze and process the received emergency starting signal to determine the represented emergency degree of the emergency starting signal, and can determine which preset links in a plurality of preset links can be skipped to execute (namely, the preset links can be skipped) in the first stage and which working parameters in a plurality of working parameters can be set without being set (namely, the working parameters can be skipped) according to the determination result. In other words, it is determined which preset links have to be executed and which parameters need to be set by medical staff in the current emergency degree, and each skipped link and skipped working parameter determined in different emergency degrees may be determined according to a plurality of preliminary experiments or may be determined in real time according to a corresponding software algorithm, which is not limited herein. In addition, the lower limit of the number of the skipped preset links and the skipped working parameters is at least one, and the upper limit of the number of the skipped working parameters is the same as the number of the preset links and the working parameters required for normal working, respectively.
Step S200, executing the remaining preset links except the skipped preset link in the plurality of preset links until the execution of the remaining preset links is confirmed to be completed, acquiring the remaining working parameters except the skipped working parameters in the plurality of working parameters and calling the preset working parameters corresponding to the skipped working parameters from the plurality of preset working parameters;
the control device of the cardiopulmonary resuscitation machine can skip each preset link determined as being capable of skipping the preset link in the first stage in the process of controlling the cardiopulmonary resuscitation machine to be started emergently, and only execute the non-skipped link, namely only execute the rest preset links in the plurality of preset links, thereby saving the time occupied by executing the skipped preset links in the first stage. After the execution of the preset link is finished, in the second stage, all the working parameters determined to be the working parameters capable of being skipped can be obtained in a skipping mode, only the rest working parameters in the working parameters are obtained, and the working parameters of the type corresponding to the working parameters capable of being skipped are called from the prestored working parameters to be used as substitutes, so that the time for setting the working parameters capable of being skipped by an operator in the second stage is saved. In addition, the number of the preset working parameters can be matched with the number of the working parameters required by the normal start of the cardiopulmonary resuscitation machine, and each preset working parameter can be preset according to the first-aid standard specification so as to ensure the final pressing effect.
In this embodiment, the preset working parameter is one or more combinations of a preset pressing depth parameter, a preset pressing frequency parameter, a preset pressing release ratio parameter, and a preset ventilation mode; the preset pressing depth parameter can be a distance that the pressing assembly advances when pressing each time, namely a preset distance between the first position and the second position; the preset pressing frequency parameter can be the number of times that the pressing component moves from the starting position to the end position and returns from the end position within one minute; the preset press release ratio parameter may be a ratio of the time during which the pressing motion and the releasing motion last, i.e., a ratio of the time from the movement of the pressing member from the starting position to the ending position to the movement thereof from the ending position to the starting position; the preset ventilation mode is also called as a preset compression ventilation ratio parameter, and can be the ratio of the number of times of compression to the number of times of ventilation. In the actual rescue process, the medical staff does not have enough time to set the working parameters, and in more cases, the working parameters are quickly set according to the emergency standard specification or the past setting experience, so in this embodiment, the emergency standard specification may be the AHA standard, the preset pressing depth parameter may be 5cm to 6cm, the preset pressing frequency parameter may be 100 times to 120 times, the preset pressing release ratio parameter may be 1:1, and the preset ventilation mode may be 30: 2 to ensure the versatility and effectiveness of the pressing effect.
Step S300, driving the driving component to work according to the obtained residual working parameters and the called preset working parameters, so that the driving component drives the pressing component to be movably switched between a first position and a second position, wherein the first position and the second position are spaced by a preset distance along the axial direction of the pressing component;
the acquired working parameters and the called preset working parameters meet the parameter requirements of the second stage of the cardiopulmonary resuscitation machine, and the control device of the cardiopulmonary resuscitation machine can directly control the driving component to work according to the remaining working parameters and the called preset working parameters after calling the preset working parameters, so that the time for triggering, starting and pressing by operators is saved. The driving assembly can drive the pressing assembly to be movably switched between the first position and the second position when working, and therefore the pressing function of pressing along the axial direction of the pressing assembly is achieved. It is understood that one of the first position and the second position may be a starting position, the other one may be an ending position, a preset distance between the two positions is a pressing depth, the preset distance is determined by the pressing depth parameter set by the operator during normal start, and in this embodiment, the preset distance may be determined by the pressing depth parameter set by the operator or the preset pressing depth parameter.
The technical scheme of the application is explained by the fact that the emergency starting switch can output emergency starting signals representing three emergency degrees of 'slight emergency', 'general emergency' and 'special emergency', when the emergency starting switch outputs the emergency starting signals representing 'slight emergency', the control device of the cardiopulmonary resuscitation machine can skip a skipped preset link and obtain a skipped working parameter for emergency starting, and starting time is shortened by a small amount; when the emergency starting switch outputs an emergency starting signal representing 'general emergency', the control device of the cardiopulmonary resuscitation machine can skip half of the skipped preset links and obtain half of the skipped working parameters for emergency starting so as to quicken the starting time quickly; when the emergency starting switch outputs an emergency starting signal representing 'special emergency', the control device of the cardiopulmonary resuscitation machine can skip all the skipped preset links and obtain all the skipped working parameters for emergency starting so as to achieve the fastest starting time.
So, make medical personnel can trigger urgent starting switch according to the difference of the on-the-spot emergency of first aid, trigger urgent starting signal of different output, so that cardiopulmonary resuscitation machine at the start-up in-process, can correspondingly save and carry out and can skip the time that the preset link took at first stage, operating personnel can skip the duration that operating parameter took and operating personnel triggers to open the time of pressing at the second stage setting, the start-up duration of cardiopulmonary resuscitation machine that has showing has reduced is favorable to improving the first aid success rate to patient.
Referring to fig. 1, in an embodiment of the present invention, the determining at least one preset link of a plurality of preset links as a skipped preset link according to the emergency start signal specifically includes:
and determining a corresponding emergency degree gear and at least one preset link which is stored in association with the determined emergency degree gear according to the emergency starting signal, and taking each preset link which is stored in association as a skipped preset link.
The control device of the cardiopulmonary resuscitation machine can be prestored with a plurality of emergency degree gears, each emergency degree gear can also be prestored with at least one preset link in a correlated manner, so that when an emergency starting signal is received, the emergency starting signal can be matched with the plurality of emergency degree gears to determine the matched emergency degree gear, and each preset link stored in a correlated manner can be called according to a matching result to be used as a skipped preset link to be skipped when the cardiopulmonary resuscitation machine is in emergency starting. With the arrangement, compared with the method for determining the skipped preset link corresponding to the emergency gear in real time by adopting the algorithm, the operation time of the control device of the cardiopulmonary resuscitation machine can be saved, so that the starting time length is further reduced.
Referring to fig. 1, in an embodiment of the present invention, before step S100, the method for controlling a cardiopulmonary resuscitation machine further includes:
step S400, acquiring a plurality of preset links required to be executed during normal starting of the cardiopulmonary resuscitation machine, and respectively establishing a plurality of preset link groups A according to the plurality of preset links0-AmEach preset link group comprises at least one preset link;
step S400 may occur at a program writing stage of a control device of the cardiopulmonary resuscitation machine, and when the control device finishes writing a control program for controlling other functional components at a first stage in a normal start, a function that is controlled and executed by each other functional component at the stage is acquired and stored as a preset link. In step S400, the control device may establish a plurality of preset link groups (a) according to a plurality of preset links, respectively0-Am) The number of preset link groups, i.e. the value of m +1, may be equal to the factorial of the number of preset links, for example, A, B, C, and 3 preset links may establish 6 preset link groups, which are a, B, C, AB, BC, AC, and ABC, respectively. Therefore, the established multiple preset link groups can traverse the combination of all the preset links, and the comprehensiveness of the preset link groups is improved.
Step S500, Slave A each time0-AmSelecting a preset link group, using each preset link in the selected preset link group as a skipped preset link, and executing the remaining preset links except the skipped preset link in the plurality of preset links until A0-AmThe selection is finished;
control device of cardiopulmonary resuscitation machineThe method comprises the steps of selecting a preset link group from a plurality of preset link groups, setting each preset link in the preset link group as a skipped preset link, and controlling other functional components to skip the current emergency start of the skipped preset link, namely, the current residual preset link is used for the emergency start. Repeating the above process for multiple times, and skipping the selected preset link group during each selection until A0-AmAll the preset link groups are selected once. In other words, the preset links in different preset link groups are taken as skipped preset links, and the starting test is performed.
Step S600, acquiring starting time T of the cardio-pulmonary resuscitation machine after the completion of starting in different residual preset links0-TmFrom T0-TmAnd selecting a preset number of starting times as a plurality of emergency degree gears respectively, and performing associated storage on each preset link in a preset link group corresponding to each selected starting time and the emergency degree gear corresponding to each starting time.
The cardio-pulmonary resuscitation machine can be further provided with a displacement sensor for detecting the displacement of the pressing component and outputting a displacement detection signal to a control device of the cardio-pulmonary resuscitation machine, so that the feedback of the pressing depth is realized. The control device of the cardiopulmonary resuscitation machine may acquire the displacement detection signal output by the displacement sensor when performing emergency start in different remaining preset links, and it can be understood that when receiving the displacement detection signal, it indicates that the cardiopulmonary resuscitation machine has been successfully started, so the control device of the cardiopulmonary resuscitation machine may determine the start time corresponding to each preset link group according to the time difference between "the preset link in different preset link groups is taken as the skipped preset link" and "the displacement detection signal is received" in step S500.
