[0062] an air pre-treatment module arranged inside the air pump module for pre-treating air before the air pump module pumps air to the air bag module.

[0063] The beneficial effects of the above technical solution are that the portable external counterpulsation therapeutic instrument for family comprises a pulse signal detection module, an air bag wearing state detection module and an air bag contact state detection module for collecting a pulse signal of a target object, real-time wrapping pose state information of an air bag module on a body part of the target object and contact state information between the air bag module and the body part of the target object, so as to control a first working state and a second working state of an air pump module for pumping and extracting air to the air bag module, and an air pre-treatment module is further used for pre-treating air before the air pump module pumps air to the air bag module. The pulse signal of the target object is directly collected as a reference for controlling the action of the air pump, so that a large-volume electrocardiogram detection device and a complex electrocardiogram analysis circuit are not needed, and the air pump with small volume can be used to realize the inflation and extraction operation of the air bag, so as to reduce the volume of the external counterpulsation therapeutic instrument and the complexity of the internal circuit structure, and improve the portability of the external counterpulsation therapeutic instrument.

[0065] The pulse sensing module is used to collect the pulse signal of the corresponding body part of the target object;

[0066] The pulse signal preprocessing module is used to amplify and filter the pulse signal and then send the pulse signal to the control module;

[0067] The control module analyzes and processes the received pulse signal to determine the actual signal ratio of the received pulse signal. If the actual signal ratio is greater than or equal to the preset signal ratio threshold, the control module sends a trigger instruction to the air pump module, instructing the air pump module to enter the corresponding working mode.

[0068] The beneficial effects of the above technical solution are as follows: by replacing the existing electrocardiogram (ECG) detection equipment with a pulse sensing module, the pulse signal detection module can be effectively reduced. Furthermore, compared to ECG signals, pulse signals have a simpler signal structure and are less difficult to process. This eliminates the need for the control module to incorporate complex signal processing circuitry, enabling efficient and accurate analysis and processing of pulse signals. Furthermore, based on the actual signal ratio of the received pulse signal, the air pump module is instructed to enter the corresponding operating mode only when the actual signal ratio is greater than or equal to a preset signal ratio threshold.

In the above manner, the gasbag module is provided with a plurality of sub-gasbags arranged in an array, each sub-gasbag is independently charged and discharged, thereby realizing independent expansion and contraction action to facilitate pressing different regions of the body part of the target object with different intensities, and improving the external counterpulsation effect.

[0075] The control module analyzes and processes the pulse signal to extract corresponding pulse diastolic and systolic switching frequency information from the pulse signal; and according to the pulse diastolic and systolic switching frequency information, the action switching frequency of the air pump module pumping air and extracting air to each sub-gasbag of the gasbag module is controlled.

[0076] The beneficial effects of the above technical solutions are: by taking the pulse diastolic and systolic switching frequency information of the target object as a reference, the action switching frequency of the air pump module pumping air and extracting air to each sub-gasbag of the gasbag module is controlled, so that each sub-gasbag can be pumped and extracted with the corresponding action switching frequency, thereby ensuring that each sub-gasbag expands and contracts at a specific rhythm to press the corresponding body part rhythmically.

[0084] The beneficial effects of the above technical solutions are: the surface of the body part of the target object has corresponding static electricity, and when the airbag module is in contact with the body part of the target object, each electrostatic sensor can detect the electrostatic distribution state information of the outer surface region in contact with the body part of the target object, so that the area range information of the overall contact between the outer surface of the airbag module and the body part of the target object (i.e. the contact area range) can be accurately determined subsequently, and the contact area between different sub-airbags in the airbag module and the body part of the target object can be calibrated subsequently.

[0085] Preferably, the second working state of the control module for controlling the air pump module to pump and extract air to the airbag module according to the real-time package pose state information and the contact state information specifically includes:

[0086] The control module judges the actual contact area value between the outer surface of each sub-airbag and the body part of the target object according to the comprehensive relative pose information and the area range information.

[0088] The beneficial effects of the above technical solutions are: through the above-mentioned manner, the actual contact area value between the outer surface of each sub-air bag and the body part of the target object can be accurately obtained, if the actual contact area value is less than or equal to the preset area threshold value, the rate of the air pump module pumping air and / or extracting air to the air bag module can be increased, or the valve opening value of the electromagnetic valve corresponding to each sub-air bag during the process of the air pump module pumping air to the sub-air bag can be increased, so that the corresponding sub-air bag can be inflated and contracted greatly in a short time, and the pressing intensity on the body part is increased, if the actual contact area value is greater than the preset area threshold value, the rate of the air pump module pumping air and / or extracting air to the air bag module can be reduced, or the valve opening value of the electromagnetic valve corresponding to each sub-air bag during the process of the air pump module pumping air to the sub-air bag can be reduced, so that the sub-air bag will not exert excessive pressing intensity on the body part when the contact area with the body part is large, and the adverse effects on the blood vessels of the body part are prevented.
