Detailed Description
The present disclosure is described in further detail below with reference to the attached drawings.
The embodiment of a sheet-type physiological signal sensing device as shown in fig. 1 comprises a physiological signal sensing area 30 for sensing a physiological signal; the physiological signal sensing area 30 is arranged above the substrate layer 10; when the bottom layer 10 is laid flat, the physiological signal sensing region 30 is also flattened to form the physiological signal sensing region 30 which is laid flat. When the substrate layer 10 is laid flat, the physiological signal sensing region 30 is also flattened to form the flat physiological signal sensing region 30. In some applications, the physiological signal sensing region 30 is disposed horizontally to facilitate acquisition of physiological signals. For example, in the monitoring of a newborn or a bedridden person, the bed sheet type physiological signal sensing device is adopted, so that various physiological signal sensing electrodes are not pasted on the skin of the newborn or the bedridden person, the part of the newborn or the bedridden person for detecting the physiological signals is only required to be exposed, and the back of the newborn or the bedridden person can be only exposed when only electrocardiosignals are required to be detected. Of course, the bed sheet type physiological signal sensing device is also suitable for the test environment in which the neonate or the bedridden person is completely exposed.

In the embodiment of the sheet-type physiological signal sensing device shown in fig. 1 and 2, the physiological signal sensing area made of a material capable of sensing electrocardiosignals of a human body is used for sensing the electrocardiosignals; the physiological signal sensing area comprises a first sensing area 31, a second sensing area 32 and a third sensing area 33; any one of the first sensing region 31, the second sensing region 32 and the third sensing region 33 is used as any one of a first electrode region, a second electrode region and a third electrode region for sensing the electrocardiosignals. The first electrode area, the second electrode area and the third electrode area enable the bed sheet type physiological signal sensing device to be provided with three electrocardiosignal acquisition areas, and the simplest electrocardiosignal of one lead can be acquired according to the three electrode areas.

The first sensing region, the second sensing region, and the third sensing region are movably disposed above the substrate layer. Any one of the first induction area, the second induction area and the third induction area can be moved very conveniently; so that the space between the three sensing areas can be adjusted according to the body size of the measuring object to obtain the layout of the three sensing areas suitable for the measuring object.

Of course, the three electrode regions, namely the first electrode region, the second electrode region and the third electrode region, can be arranged at equal intervals, which is equivalent to arranging three electrocardiosignal acquisition regions at equal intervals.
The distance among the first electrode area, the second electrode area and the third electrode area can be flexibly adjusted according to the actual situation of a measuring object. For example, when a measuring object is locally injured or is not suitable for measurement, the electrode area can be flexibly arranged, so that the physiological signals can be collected and acquired under various conditions. Greatly facilitates the scene of physiological signal acquisition which is not suitable for adopting common electrodes and sensors. By adopting the bed sheet type physiological signal sensing device, an acquisition object can lie on the bed sheet type physiological signal sensing device, and then almost non-inductive physiological signal acquisition can be carried out; the signal acquisition mode greatly improves the comfort of the acquired object without any electrode application. In the night sleep monitoring, the physiological signal detection in the sleep state is greatly facilitated, and the device is a revolutionary physiological signal sensing and collecting device.
In the embodiment of the sheet-type physiological signal sensing device shown in fig. 3 and 4, at least six electrocardio-electrodes 50 are arranged in any one of the first electrode region, the second electrode region and the third electrode region for electrocardio-signal sensing; a plurality of electrocardio electrodes in the electrode area are distributed according to the arrangement mode of the chest lead collecting electrodes.

Several of the first peripheral physiological signal sensing area 61, the second peripheral physiological signal sensing area 62, the third peripheral physiological signal sensing area 63 and the fourth peripheral physiological signal sensing area 64 can be arbitrarily selected for twelve-lead electrocardiographic acquisition. In the embodiment shown in fig. 5, the first peripheral physiological signal sensing area 61, the second peripheral physiological signal sensing area 62, the third peripheral physiological signal sensing area 63 and the fourth peripheral physiological signal sensing area 64 can be sensing areas which are flattened following the flattening of the substrate layer; the sensing binding bands can be arranged on the sensing areas and bound on the detected limbs to acquire physiological signals and play a role in fixing the limbs.
In the embodiment of the sheet-type physiological signal sensing device shown in fig. 1 to 7, any one of the first sensing region, the second sensing region and the third sensing region is used as a respiration sensing electrode region while being used for sensing an electrocardiosignal; when the electrode area is used as a respiration sensing electrode area, a pressure sensor is arranged in the sensing area, and the pressure sensor senses respiration signals in a pressure change sensing mode; of course, any one of the three electrode regions, i.e., the first electrode region, the second electrode region, and the third electrode region, may be used as the electrocardiographic signal sensing electrode region and the respiration sensing electrode region at the same time. When the pressure sensor is used for breathing sensing, the pressure sensor is arranged in the sensor, and breathing signals are obtained according to pressure changes sensed by the pressure sensor. Such a respiratory signal acquisition has a higher reliability; because the pressure sensor is adopted to directly sense the pressure change caused by respiration, the respiration signal is directly obtained from the pressure change, and the method is adopted to collect the respiration signal, and the anti-interference performance of the method is greatly superior to that of a respiration impedance method between two electrocardio electrodes.
