Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
First embodiment
Referring to fig. 1, fig. 1 is a schematic side view of a seat according to a first embodiment of the present invention. As shown in fig. 1, the seat includes: the detection device comprises a left handrail 10, a right handrail, a conductive leather layer 11, a first detection electrode 12 and a second detection electrode, wherein the first detection electrode 12 is positioned between the left handrail 10 and the conductive leather layer 11, and the second detection electrode is positioned between the right handrail and the conductive leather layer 11; the first detection electrode 11 and the second detection electrode are connected with the electrocardio acquisition module and used for acquiring the body limb lead signals of the human body and transmitting the body limb lead signals to the electrocardio acquisition module.
Specifically, only the left armrest 10 of the seat is shown in fig. 1, and since the left armrest 10 and the right armrest are substantially the same, only the left armrest 10 is shown, and the first detection electrode 12 on the left armrest 10 and the conductive leather layer 11 on the left armrest 10 are shown for illustration. The left armrest 10 is covered with a conductive leather layer 11, and the conductive leather layer 11 is a PU leather that can collect human body electrodes (human body electrical signals), has advantages in contact resistance, hydrophilicity, resistance, and the like, and can also be directly used as a coating material of the armrest. A first detection electrode 12 is arranged between the left handrail 10 and the conductive leather layer 11, and the first detection electrode 12 is connected with the electrocardio-acquisition module and is used for acquiring electrocardiosignals of limbs of a human body, such as the left arm. Similarly, a second detection electrode is arranged between the right handrail and the conductive leather layer 11, and the second detection electrode is connected with the electrocardiosignal acquisition module and is used for acquiring electrocardiosignals of limbs of a human body, such as the right arm. The first detection electrode 12 and the second detection electrode form a bipolar limb lead in the electrocardiographic detection, and a human limb lead signal is collected to the electrocardiographic collection module to reflect the potential difference between the two limbs.
It should be noted that the left arm and the right arm mentioned above may include any parts of the corresponding limbs of the human body, for example, the arm may include at least a hand, a wrist, a forearm, an elbow, and an arm. Therefore, the first and second detection electrodes 12 and 12 may be disposed at positions that are normally accessible on the corresponding armrest, such as the upper surface and the side surface of the left armrest 10 and a finger contact area when an arm is normally placed. Correspondingly, the conductive leather layer 11 can wrap the armrest completely, and can also cover the area where the detection electrode (the first detection electrode 12 and the second detection electrode) is located, as shown in fig. 1 and fig. 2, the covering layer of the left armrest 10 in fig. 1 includes the conductive leather layer 11 and the non-conductive leather layer 18, that is, the non-conductive leather layer 18 is a common covering layer of the armrest, and cannot detect the human body electrode, and the conductive leather layer 11 that can be used for detecting the human body electrode only covers the area where the detection electrode is located, and the conductive leather layer 11 and the non-conductive leather layer 18 can form a completed armrest covering layer by sewing or the like. Whereas the coating of the left handrail 10 in figure 2 is entirely a conductive leather layer 11. The coating forms of the two handrails can well solve the problems that the existing electrocardiogram detection chair is more obtrusive in appearance and not high in integrity.
It is worth mentioning that the conductive leather layer 11 can be synthesized by adding polyurethane resin raw material into the composite adhesive composed of the conductive filler such as metal powder or graphite and synthetic resin, and it also has conductive leather layer made by other methods, for example, the conductive layer is provided in the base layer surface and the base layer surface of the artificial leather or the animal leather, and the conductive layer is embedded in the base layer surface of the artificial leather or the animal leather by graphite powder or metal powder through high pressure. The leather can be made of artificial leather materials such as PU or PVC.

Specifically, in order to facilitate the acquisition of the electrocardiographic signals, electrode pads may be disposed in different regions of the armrest, that is, the left armrest 10 and/or the right armrest may include a plurality of electrode pads located in different regions. For example, electrode plates can be arranged in each area of the armrest so as to be in contact with each part of the arm, and due to the equipotential of each electrode plate, the electrocardiosignal acquisition can be realized by contacting any one or more electrode plates. In order to make the appearance of the chair armrest uniform, the whole armrest can be wrapped by the conductive leather layer 11.
In one embodiment, an elastic structure is disposed under the first detection electrode 12 and/or the second detection electrode for tightly adhering the corresponding detection electrode to the conductive leather layer 11.
Specifically, the detection electrodes (the first detection electrode 12 and the second detection electrode) are disposed between the handrail and the conductive leather layer 11, and may be embedded between the conductive leather layers 11, that is, the conductive leather layer is an inner layer, or may be fixed on the handrail, and the conductive leather layer 11 covers the detection electrodes. Regardless of the setting mode, the conductive leather layer 11 has a certain thickness and elasticity, and the shape and the flatness of the handrail are different, so that the electrocardiosignal of the limb collected by the detection electrode is more stable and accurate, an elastic structure, such as a spring, is arranged below the detection electrode, so that the detection electrode is better attached to the conductive leather layer 11 under the action of the elastic structure, so that the electrocardiosignal can be better collected, of course, the lower part of the detection electrode can be the lower part in direct contact or the lower part in indirect contact, namely, the detection electrode is embedded between the conductive leather layers 11, namely, the inner layer of the conductive leather layer 11 can also be fixed on the handrail.
In one embodiment, the first detection electrode 12 and the second detection electrode are capacitively coupled non-contact electrocardio-electrodes.
In one embodiment, the first detection electrode 12 and the second detection electrode are contact low polarization dry electrodes.
In particular, the contact type low-polarization dry electrode can be a silver/silver chloride electrode, a titanium nitride electrode, a platinum electrode or the like, and has the advantage of being reusable.
In one embodiment, the chair further comprises a first lead wire connecting the first detection electrode 12 and the electrocardiograph acquisition module, and a second lead wire connecting the second detection electrode and the electrocardiograph acquisition module.
Specifically, the first lead wire and the second lead wire are used for transmitting the human body electrocardiosignals collected by the detection electrode to the electrocardio collection module. It is worth mentioning that, in order not to influence the original appearance of the seat, the lead wire can be integrated and arranged in the seat, the contact connection mode can be adopted to be connected with the detection electrode, the electrocardio acquisition is carried out, the contact connection is carried out between the lead wire and the contact on the seat, so as to carry out the transmission of the electrocardio signals of the human body, and the contact is connected with the detection electrode through the lead wire in the seat.
It should be noted that the above embodiments are not intended to be illustrative, but rather absolute, as will be appreciated by those skilled in the art.
