The combinations of letters and numbers "S," "M," and "H" in this application are also for ease of explanation, and their specific meanings are determined by the specific content they refer to.

[0046] Existing single-finger gripping technology provides only the space of one finger for contact. This limited space prevents full contact when mounting multiple different types of sensing components. For example, multi-parameter sensors integrating ECG, body temperature, respiration, and blood oxygenation require space for electrode placement, as do body temperature and respiration electrodes. The technical problem this application aims to solve is how to provide more contact space while achieving full contact of multiple parameters in a single operation.

[0072] The sensing components or sensors within the probe assembly include ECG electrodes, which are used to contact the human body surface to perform ECG sensing and acquire ECG signals, i.e., to acquire ECG signals from the body surface at the corresponding location.

[0073] The sensing components or sensors within the probe assembly include respiratory electrodes, which can be respiratory sensing devices based on pressure sensors or acceleration sensors, used to contact the human body surface to sense and acquire respiratory signals.

[0074] Respiratory electrodes can also be integrated with electrocardiogram (ECG) electrodes, that is, respiratory signals are obtained based on ECG electrodes.

[0075] The light-emitting component in the probe assembly can be an SpO2 light source, i.e., a light source used for blood oxygen saturation measurement; the light-detecting component can be an SpO2 detector. In embodiments of the probe assembly, if blood oxygen measurement is to be performed, at least one probe assembly includes a light-emitting component and a light-detecting component.

[0076] like Figure 3 and Figure 4 The B-channel sensing component is a two-parameter fusion probe assembly, including ECG electrodes and body temperature electrodes.

[0080] like Figure 2 and Figure 3It also includes a light-shielding plate A 0217 and a light-shielding plate B 0278. One side of the light-shielding plate A 0217 is connected to the edge of the clamping part A1 0210, and one side of the light-shielding plate B 0278 is connected to the edge of the clamping part B1 0270. When the V-shaped rotating torsion spring is in the open or closed state, the light-shielding plate A or the light-shielding plate B is used to block the light on the left and right sides of the sensing device.

[0081] The light-shielding plates A and B are different sizes. The larger light-shielding plate is positioned on one side of the blood oxygen sensor component to prevent external light from affecting PPG signal detection or blood oxygen saturation measurement calculation. PPG stands for Photoplethysmography. PPG works by emitting light of a specific wavelength (such as green, red, or infrared light) onto the skin and detecting changes in light absorption caused by changes in blood volume, thereby monitoring physiological parameters such as heart rate and blood oxygen saturation.
