[0040] It is worth noting that the defibrillator body 1 is electrically connected with the electrode sheet lead 9, the end of the electrode sheet lead 9 is provided with a side electrode sheet 7, the side electrode sheet 7 is provided with a thermal breaking part 8, which provides mechanical power for the automatic separation of the detection part and the electrode sheet, ensures that the device does not have excessive contact with the patient before defibrillation, and avoids the influence of electrical elements by pulse, the thermal breaking part 8 includes a temperature insulation plate 81, which is made of high-temperature-resistant polyurethane foam, cooperates with the wrapped aerogel felt to effectively attenuate the 100℃ heat to the acceptable temperature of the human body surface, can maintain structural stability in low temperature environment, avoids the decline of heat insulation performance caused by temperature change, the temperature insulation plate 81 is bonded on the side electrode sheet 7, attenuates the heat transmitted by the heating sheet 67 through the temperature insulation plate 81, avoids the direct contact of high temperature with the patient's body surface to cause burns, and at the same time ensures that appropriate heat is transmitted to the side electrode sheet 7 to improve the adhesion, the side electrode sheet 7 is rotatably connected with a rotating disc 82, the rotating disc 82 is fixedly connected with a copper sheet 83, the copper sheet 83 is fixedly connected with an iron sheet 84, based on the difference of metal thermal expansion coefficient, the copper sheet 83 and the iron sheet 84 can be bent after heating, the locking state is released, the detection part and the electrode sheet are automatically separated, the copper sheet 83 is provided with a lock hole 85 corresponding to the lock rod 66, the number of the side electrode sheet 7, the electrode sheet lead 9 and the thermal breaking part 8 is two, the mounting part 3, the two detection parts 4, the safety part 5 and the locking part 6 together form a single-side detection mechanism, and the number of the single-side detection mechanism is two.

[0041] The working principle is that the supporting arm 41 of the detection part 4 is kept reset tension by the torsion spring 43, the two ends of the supporting arm 41 are abutted by the pressure column 44 with a cutting surface structure, the bottom of the supporting arm 41 is abutted by the two sides of the limiting groove 62 of the supporting table 61 of the locking part 6, further limiting the rotation of the supporting arm 41, and the rotating rod 42 of the detection part 4 is fixedly connected with the rotating shaft 54 of the safety part 5, the gear 55 on the rotating shaft 54 is engaged with the toothed arm 53 in the sliding hole, at this time, the toothed arm 53 does not trigger the button switch 52 of the safety part 5, and the initial state is off.

[0042] The side electrode sheet 7 is electrically connected with the defibrillator body 1 through the electrode sheet lead wire 9, and the heat insulation plate 81 of the thermal breaking part 8 is bonded to the surface of the side electrode sheet 7. After the first-aid personnel paste the two side electrode sheets 7 on the chest of the patient, the copper sheet 83 is aligned and inserted into the insertion hole 63 by rotating the rotating disc 82, the magnet 64 in the insertion hole 63 adsorbs the iron sheet 84 on the copper sheet 83 through magnetic attraction, and the locking rod 66 in the rod sleeve 65 is popped out under the spring tension and inserted into the locking hole 85 of the copper sheet 83, forming a mechanical locking, and the side electrode sheet 7 and the heat insulation plate 81 and the mounting disc 31 form an integrated fixed structure.

[0043] At the same time of the above locking, since the side electrode sheet 7 has been pasted on the surface of the patient, the distance between the mounting disc 31 and the side electrode sheet 7 is reduced, the pressure column 44 is lowered and preferentially contacts the back of the side electrode sheet 7, prompting the pressure column 44 to drive the supporting arm 41 to rotate around the rotating rod 42, and then the two pressure columns 44 are away from each other and press the side electrode sheet 7 again, so as to improve the adhesion to the surface of the patient, avoid the loosening of the side electrode sheet 7 to generate a gap, the pressure column 44 continues to slide to the surface of the patient, and the supporting arm 41 synchronously drives the rotating rod 42 and the coaxial rotating shaft 54 to rotate, the gear 55 on the rotating shaft 54 rotates with the rotating shaft 54, and the toothed arm 53 is pushed to slide into the groove 51 along the sliding hole through the engagement relationship, until the end of the toothed arm 53 presses the button switch 52, after the button switch 52 is closed, the start signal is sent to the PLC slave controller, and the power supply circuit of the heating sheet 67 and the thermistor 45 is turned on, and the system is switched to the working state.

[0044] When the locking of the side electrode sheet 7 is completed, the pressure column 44 is tightly attached to the patient under the reset tension of the torsion spring 43, and is adaptively adjusted in angle through the rotating connection with the end of the supporting arm 41, so as to always make the thermistor 45 adhere to the surface of the patient to collect the temperature of the surface of the patient as the basis for subsequent pulse current energy calculation, and the temperature signal of the thermistor 45 is transmitted to the PLC slave controller through the lead wire;

[0045] The PLC slave controller performs AD conversion on the analog signal of the thermistor 45, and uploads the temperature data to the PLC master controller through the data line 34, so as to provide real-time body temperature parameters for the host energy calculation, after receiving the temperature data uploaded by the PLC slave controller through the data line 34, the PLC master controller dynamically adjusts the defibrillation pulse parameters in combination with the built-in intelligent low-temperature energy calculation algorithm of the defibrillator body 1:

[0046] If the patient's body temperature is 30-35℃, the myocardial resistance is higher than normal temperature by 6%-15%, the PLC main controller will increase the defibrillation energy from the normal temperature 120J standard value to 130J-140J, to ensure that the actual current intensity acting on the myocardium meets the standard;

[0047] If the patient's body temperature is lower than 30℃, the myocardial resistance is increased by 15%-30%, the energy output is further increased to 140J-160J, and the pulse width is adjusted from 10ms to 12ms, which adapts to the physiological characteristics of the prolongation of myocardial cell action potential duration under low temperature.

[0048] Before pulse output, the PLC continuously collects the body surface temperature from the controller through the thermistor 45 and feeds back to the PLC main controller in real time, dynamically adjusting the first pulse energy to avoid energy deficiency or excess.

[0049] The heating sheet 67 also starts synchronously with the PLC controller. The heating sheet 67 adheres to the copper sheet 83 inside the jack 63 to continuously increase the temperature, and the heat is attenuated through the thermal insulation plate 81. The attenuated temperature can be transmitted to the side electrode sheet 7 for auxiliary heating, thereby improving the adhesion and further avoiding the loosening of the side electrode sheet 7 to produce gaps.

[0050] When the temperature range of the heating sheet 67 is continuously rising from 10℃ to 100℃, the elongation of the copper sheet 83 and the iron sheet 84 is different due to the different metal thermal expansion coefficients, and based on the principle of thermal circuit breaker, the elongation of the copper sheet 83 after thermal expansion is greater than that of the iron sheet 84, thereby causing the copper sheet 83 to bend the iron sheet 84 towards one side, and the iron sheet 84 bends away from the magnet 64, the magnetic attraction effect is weakened, the lock hole 85 is elongated and bent to separate from the lock rod 66, gradually losing the locking effect. At this time, under the restoring force of the torsional spring 43, the support arm 41 is reset, which in turn promotes the automatic ejection of the jack 63 away from the thermal insulation plate 81, and further separates the installation part 3 and the detection part 4 from the side electrode sheet 7 after collecting the patient's temperature data before pulse output. This step is based on the automatic separation effect of not touching the patient's body as much as possible before pulse preparation in the process of defibrillation instrument outdoor first aid measures, which further ensures that the electrical elements in the installation part 3 and the detection part 4 are not affected by the subsequent pulse current energy and cause irreversible damage.

[0051] After separation, the gear 55 drives the tooth arm 53 away from the button switch 52, and the PLC controller is disconnected from the button switch 52, and the defibrillator body 1 starts to output pulse current energy for defibrillation.
