The technical solution of the present invention will be described in further detail with reference to more specific examples.
In one embodiment, as shown in fig. 6, the present invention provides a method for measuring a body composition parameter, in which the first measurement mode is described as an eight-electrode measurement mode, and the second measurement mode is described as a four-electrode measurement mode. The method for measuring the human body composition parameters comprises the following steps:
s401, detecting the impedance value between the preset electrode pairs.
The preset electrode pair comprises at least one electrode used for contacting the upper limb of the human body and at least one electrode used for contacting the lower limb of the human body. Accordingly, the impedance values between the preset electrode pairs include one or more of the following impedance values: an impedance value between the left upper limb and the left lower limb, an impedance value between the left upper limb and the right lower limb, an impedance value between the right upper limb and the left lower limb, and an impedance value between the left lower limb and the right lower limb.
Optionally, the impedance value between the preset electrode pair may further include at least one of the following impedance values: an impedance value between the left upper limb and the right upper limb, and an impedance value between the right upper limb and the right lower limb.
S402, if the impedance value between the preset electrode pair is in the preset effective impedance range, entering an eight-electrode measuring mode, and executing the step S403; otherwise, the four-electrode measurement mode is entered, and step S407 is executed.
The preset effective impedance range is one or more impedance intervals preset according to the impedance range of each section of the general human body. If the impedance value between the preset electrode pair is within the preset effective impedance range, the impedance loop is formed between at least one electrode for contacting the upper limb of the human body and at least one electrode for contacting the lower limb of the human body, and at this time, in order to measure the human body composition parameters of other sections of the target object except the lower half body, the eight-electrode measurement mode is entered. On the contrary, if the impedance value between the preset electrode pair is not within the preset effective impedance range, it indicates that no normal impedance loop is formed between the upper limb and the lower limb of the human body, and the body composition parameters of other segments except the lower body cannot be measured, so the four-electrode measurement mode is entered.

Wherein the plurality of second bio-impedance values include at least two of an impedance value between two upper limbs, an impedance value between a left upper limb and a left lower limb, an impedance value between a right upper limb and a left lower limb, and an impedance value between a right upper limb and a right lower limb of the target object.
Under the eight-electrode measurement mode, the impedance values of the limbs of the target object can be directly measured, and the trunk impedance value of the target object is obtained through conversion according to the impedance values of the limbs. As shown in FIG. 2, the impedance values of the left and right upper limbs of the target object are respectively represented as Z1、Z2The impedance values of the left and right lower limbs are Z3、Z4Then the torso impedance value Z of the target object5The following formula can be used for calculation:
