Please combine Fig. 1 and Fig. 8, this application also proposes a kind of control method of multifunctional resuscitator, here the multifunctional resuscitator 100 is the multifunctional resuscitator 100 of any of the above-mentioned embodiments, the control method specifically includes the following steps:

S1: When the chest compression device 30 and the abdominal compression device 10 are turned on, both receive a selection signal of an operation mode;

Here, both the chest compression device 30 and the abdominal compression device 10 have power-on buttons, and the power-on buttons are electrically connected to their respective control circuit boards. 30 and the abdominal compression device 10 are turned on, and now the display screen connected to the control circuit board can be turned on, and the respective control circuit boards are also ready to receive the user's designation at any time, so as to control the corresponding instructions.

S2: When one of the pressing main unit 31 and the pressing main unit 11 receives the selection signal, it judges whether the operation mode is a linkage mode;

When the user selects one of the devices to operate, the control circuit board of the device can respond to corresponding commands. For example, when the pressing host 31 receives the selection signal of the operating mode, the second control circuit board will judge the selection signal to determine whether it is an independent pressing mode or a linkage mode; and when the pressing host 11 receives the selection signal , the first control circuit board will judge the selection signal to determine whether it is an independent pressure boosting mode or a linkage mode.

S3: If yes, the sending part of the judging one of the pressing host 31 and the boosting host 11 sends a signal requesting connection to the receiving part of the other;

Here, when the judging result is the linkage mode, it means that the abdominal compression device 30 and the chest compression device 10 need to cooperate simultaneously for rescue. Then, the device that needs to make a judgment sends a signal requesting connection to the device that does not make a judgment, so as to realize the signal connection between the two and realize system sharing. For example, when the pressing host 31 receives a selection signal and determines that it is in linkage mode, the second control circuit board will control the sending part to send a "connection request" signal to the receiving part of the pressing host 11, so that a wireless connection can be established. Similarly, when the pressure booster 11 receives the selection signal and determines that it is in the linkage mode, its internal sending unit sends a “connection request” signal to the receiving unit of the pressing host 31 to establish a wireless connection.

S4: When receiving a signal of a successful connection, control the pressing main unit 31 to drive the pressing head 35 to perform a reciprocating pressing movement, and the pressing main unit 11 drives the pressing head 15 to perform a reciprocating pressing movement.

When the device sending the connection request receives the connection success signal, it means that the pressure-lifting host 11 and the pressing host 31 have been wirelessly connected, and the control circuit boards of the two have realized the effect of signal intercommunication. When starting or adjusting parameters is performed on one of the devices, the other device will also perform corresponding command control operations, thereby achieving a linkage effect. For example, after the connection is successful, the pressing of the start button on the display screen of the pressing host 31 realizes the reciprocating pressing movement of the pressing host 31 to the pressing head, and at this time, the control circuit board of the pressing host 11 will be at intervals The preset time controls the pressure-lifting head 15 to carry out the reciprocating pressure-lifting movement, so as to realize the alternate pressing action of the pressing head 35 and the pressure-lifting head 15 until the rescue work is completed in cooperation.

Of course, the above situation is performed on the basis that the multifunctional resuscitator 100 of the present application has been assembled. The multi-functional resuscitator 100 is used as first aid equipment, and can be stored in a backpack. The structure is simple, the assembly is convenient, and it can be further conveniently carried. When in use, first take out the first base plate 19 and the second base plate 39, put them into the back of the patient, take out the pressure-lifting host 11 and the first support arm 13, and connect them with the first base plate 19, so that the pressure-lifting head 15 is aligned with the abdomen of the patient, and then Take out the compression host 31 and the second support arm 33, and connect them with the second base plate 39, so that the compression head 35 is aimed at the patient's chest, and then connect the first support arm 13 and the second support arm 33, so that the multifunctional resuscitator After the 100 is assembled, the linkage mode of abdominal lifting and chest compression can be performed at the same time.

The multifunctional resuscitator 100 of the present application has a good pressing effect in the linkage mode, effectively ensuring the efficiency and accuracy of rescue, and at the same time, it can be disassembled and used separately, and there are multiple options for different scenarios.
