Detailed Description
The present application will now be described in further detail with reference to the accompanying drawings. The schematic diagram schematically shows the structural diagram of the cardiopulmonary resuscitation quality detection apparatus 100 in a simplified manner.
As shown in fig. 1, the cardiopulmonary resuscitation quality detection apparatus 100 according to the present embodiment mainly includes a first acceleration sensor 1, a microprocessor 2, and a display device 3. Wherein, the first acceleration sensor 1 is used for sensing a first pressing acceleration A1 of the chest pressing part of the human body, in particular, the first acceleration sensor 1 is assembled to the chest pressing part of the user when the quality detection device 100 for cardiopulmonary resuscitation is in a use state, in particular, the first acceleration sensor 1 can be a gravity acceleration sensor; the microprocessor 2 is connected with the first acceleration sensor 1 and can acquire the cardiopulmonary resuscitation compression depth S according to the first compression acceleration A1, specifically, the microprocessor 2 acquires a first compression displacement value S1 of the chest compression position of the human body by performing time domain integration or frequency domain integration on the first compression acceleration A1, wherein the first compression displacement value S1 is substantially equal to the cardiopulmonary resuscitation compression depth S, and therefore, the cardiopulmonary resuscitation compression depth S is also acquired; the display device 3 is connected with the microprocessor 2 and can display the cardiopulmonary resuscitation compression depth S, specifically, the cardiopulmonary resuscitation compression depth S can be presented in a chart form or a graph line form so as to be visually acquired by a rescuer, specifically, the display device 3 can be integrated with the microprocessor 2 together or can be set independently, and when the display device 3 is set independently, the display device can be set to be wearable, for example, the display device is set to be a wristwatch type and can be worn on the wrist of a user, so that the rescuer can conveniently observe cardiopulmonary resuscitation quality information during rescue.
Since the user is usually placed on the cushion 10 to cushion the pressure of the compression and avoid physical injury to the user caused by the compression, when the rescuer performs the cardiopulmonary resuscitation compression on the user, the cushion 10 may generate a certain elastic deformation, so the first compression displacement value S1 is usually larger than the cardiopulmonary resuscitation compression depth S, in other words, the cardiopulmonary resuscitation compression depth S obtained by only measuring the first compression displacement value S1 has a certain error, and in order to reduce the influence of the above error on the cardiopulmonary resuscitation compression quality detection result, in the present embodiment, preferably, as shown in fig. 2, the cardiopulmonary resuscitation quality detection apparatus 100 further includes: a second acceleration sensor 4 for sensing a second compression acceleration a2 of the user's back, specifically, the second acceleration sensor 4 is fitted to the user's back when the cardiopulmonary resuscitation quality detection apparatus 100 is in use, and corresponds to the position of the first acceleration sensor 4; the microprocessor 2 is connected to the second acceleration sensor 4 and is capable of acquiring the second compression displacement value S2 according to the second compression acceleration a2, and the manner of acquiring the second compression displacement value S2 is substantially the same as the manner of acquiring the first compression displacement value S1, and will not be described again. Further, the microprocessor 2 obtains the cardiopulmonary resuscitation compression depth S by calculating the difference between the first compression displacement value S1 and the second compression displacement value S2, so as to reduce the problem that the deviation of the cardiopulmonary resuscitation quality detection result is caused by the certain displacement of the back of the user during the cardiopulmonary resuscitation compression, so that the obtained cardiopulmonary resuscitation compression depth S is more accurate.
In the cardiopulmonary resuscitation compression, the compression depth and frequency directly determine whether the first aid is successful or not, and therefore, it is necessary to detect the cardiopulmonary resuscitation compression frequency F, and since one cardiopulmonary resuscitation compression depth S data is generated every compression, the cardiopulmonary resuscitation compression frequency F can be calculated from the number of samples of the cardiopulmonary resuscitation compression depth S value and the time corresponding to the cardiopulmonary resuscitation compression, and further, by taking the value of the first compression displacement value S1 as the cardiopulmonary resuscitation compression depth S as an example, the first compression displacement value S1 is set to zero, the first compression displacement value S1 changes once and returns to zero once per compression, and once every compression, that is, once cardiopulmonary resuscitation compression, the cardiopulmonary resuscitation compression is performed, so that the cardiopulmonary resuscitation compression frequency can be determined by the change frequency of the first compression displacement value S1 as the cardiopulmonary resuscitation compression frequency F, preferably, the cardiopulmonary resuscitation compression frequency F can be calculated by the microprocessor 2 and can be displayed by the display means 3 for reference by the rescuer.
In order to detect whether the quality of the cardiopulmonary resuscitation meets the requirement, in the present embodiment, threshold ranges of the cardiopulmonary resuscitation compression frequency F and the cardiopulmonary resuscitation compression depth S are set in a storage unit (not shown) of the microprocessor 2, respectively, in the process of performing the cardiopulmonary resuscitation compression, the cardiopulmonary resuscitation compression frequency F is at least 100 times/minute, and the cardiopulmonary resuscitation compression depth S is at least 5cm, and preferably, the cardiopulmonary resuscitation quality detection apparatus 100 further includes: the alarm device 5 is connected with the microprocessor 2 and can give an alarm when the cardio-pulmonary resuscitation compression depth S and/or the cardio-pulmonary resuscitation compression frequency F exceed the respective threshold ranges, so that the alarm device can not only visually display the cardio-pulmonary resuscitation compression depth S and the cardio-pulmonary resuscitation compression frequency F, but also give an alarm when the cardio-pulmonary resuscitation compression depth S and/or the cardio-pulmonary resuscitation compression frequency F exceed the threshold ranges and prompt the rescuer to make adjustments in time, specifically, the threshold range of the cardio-pulmonary resuscitation compression frequency F can be 100 times/min and 120 times/min, and the threshold range of the cardio-pulmonary resuscitation compression depth S can be 5cm-6 cm.
In the present embodiment, in order to enable the rescuer to more intuitively acquire the alarm information, the cardiopulmonary resuscitation quality detection apparatus 100 preferably further includes: an indicator light 6, the indicator light 6 being connected to the microprocessor 2 and being capable of emitting an indicator signal when the cardiopulmonary resuscitation compression depth S and/or the cardiopulmonary resuscitation compression frequency F exceeds the upper/lower limit of the respective threshold range.
It should be noted that the alarm 5 and the indicator lamp 6 may be integrated with the display device 3 or may be provided separately.
In this embodiment, the microprocessor 2 is preferably a STM32F103RET6 processor, which is small and inexpensive, and which enables the cpr quality monitoring device 100 to be small, portable, and inexpensive to manufacture while performing the above-described functions.
