The pulling portion may be a pulling hole or a pulling protrusion, and is not limited herein.

Meanwhile, in order to monitor the working state of the multifunctional resuscitator 100 conveniently, the pressure-increasing host 11 and the pressure-pressing host 31 are both provided with display devices, and the display devices are electrically connected with respective circuit boards and can display parameters controlled by the circuit boards. Meanwhile, the display device is also provided with a control button, so that a user can conveniently carry out related adjustment.

Referring to fig. 1 and fig. 8, the present invention further provides a control method of a multifunctional resuscitation machine, where the multifunctional resuscitation machine 100 is the multifunctional resuscitation machine 100 according to any one of the embodiments, the control method specifically includes the following steps:

s1: under the condition that the chest compression device 30 and the abdomen pressure raising device 10 are started, the chest compression device and the abdomen pressure raising device receive selection signals of operation modes;

here, the chest pressing device 30 and the abdomen lifting and pressing device 10 both have a power button, the power button is electrically connected with respective control circuit boards, when the two are needed to be used simultaneously, the power buttons of the two can be pressed respectively, so that the chest pressing device 30 and the abdomen lifting and pressing device 10 are powered on, at this time, a display screen connected with the control circuit boards can be started, and meanwhile, the respective control circuit boards are also prepared to receive the designation of a user at any time, thereby controlling corresponding instructions.

S2: when the received selection signal is one of the pressing main machine 31 and the lifting main machine 11, judging whether the running mode is the linkage mode;

when a user selects one of the devices to operate, the control circuit board of the device can respond to corresponding instructions. For example, when the pressing host 31 receives a selection signal of an operation mode, the second control circuit board may determine the selection signal, and determine whether the selection signal is an independent pressing mode or an interlocking mode; when the pressure increasing host 11 receives the selection signal, the first control circuit board determines the selection signal to determine whether the pressure increasing host is in the independent pressure increasing mode or the linkage mode.

S3: if yes, the sending part of one of the pressing host machine 31 and the pressure-raising host machine 11 which makes a judgment sends a signal for requesting connection to the receiving part of the other one;

here, when the determination result is the link mode, it is described that the abdomen lifting and pressing device 30 and the chest compression device 10 need to be simultaneously matched to perform rescue. The device which needs to be judged initiates a signal for requesting connection to the device which does not need to be judged, thereby realizing the signal connection of the device and realizing the system sharing. For example, when the pressing host 31 receives the selection signal and determines that the mode is the linkage mode, the second control circuit board controls the transmitting part to transmit a "connection request" signal to the receiving part of the pressing host 11, so that the wireless connection can be established. Similarly, when the pressure increasing host 11 receives the selection signal and determines that it is in the linkage mode, the transmitting unit in the pressure increasing host sends a "connection request" signal to the receiving unit of the pressure host 31, and a wireless connection is established.

S4: when a signal of successful connection is received, the pressing host machine 31 is controlled to drive the pressing head 35 to perform reciprocating pressing motion, and the pressure raising host machine 11 drives the pressure raising head 15 to perform reciprocating pressure raising motion.

When the device sending the request connection receives the signal of successful connection, it indicates that the pressure host 11 and the pressure host 31 are wirelessly connected, and the control circuit boards of the two achieve the effect of signal intercommunication. When one device is started or parameters are adjusted, the other device can also carry out control operation of corresponding instructions, and therefore the linkage effect is achieved. For example, after the connection is successful, the pressing of the pressing head by the pressing host 31 is realized by pressing the start button on the display screen of the pressing host 31, and at this time, the control circuit board of the pressure increasing host 11 controls the pressure increasing head 15 to perform reciprocating pressure increasing movement at preset intervals, so that the pressing head 35 and the pressure increasing head 15 are alternately pressed down until the rescue work is completed in cooperation.

This is, of course, done on the basis that the multifunctional resuscitation machine 100 of the present application has been assembled. Multifunctional resuscitation machine 100 is taken in as first aid equipment, optional knapsack, simple structure, and the equipment is convenient, can further conveniently carry. First bottom plate 19 and second bottom plate 39 are taken out earlier during the use, put into patient's back, take out carrying and pressing host computer 11 and first support arm 13, be connected with first bottom plate 19, make and carry and press head 15 to aim at patient's belly, will press host computer 31 and second support arm 33 again and take out, be connected with second bottom plate 39, make and press head 35 to aim at patient's chest, connect first support arm 13 and second support arm 33 again, so, multi-functional resuscitator 100 is assembled and is finished, can carry out the linkage mode that the belly carried out simultaneously with chest compression.

The utility model provides a multi-functional resuscitator 100's linkage mode is pressed effectually, effectively guarantees the efficiency and the rate of accuracy of rescue, can also tear apart and use alone simultaneously, has multiple selection to different scenes.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
