Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

The traditional integrated single-lead electrocardiogram acquisition equipment has the following problems that the equipment is easy to move due to skin tightness or muscle contraction generated during movement or breathing, so that the contact point of an equipment sensor and the skin moves, movement noise is generated, and the acquisition quality of equipment signals is influenced.

The following describes embodiments of the present invention in detail with reference to the accompanying drawings.

The utility model provides a sensor device of electrocardio is led to list, the electrocardio collection equipment that leads of original integral type divides into two independent electrocardio sensor, link to each other it through the cable, the cable adopts soft material and leaves certain radian, skin elasticity or muscle shrink that produce when because of human motion or breathing like this, the collection sensor is along with skin and muscle shrink synchronous motion, the distance of two sensors is controlled along with the removal of collection sensor to soft cable, the normal work of equipment is not influenced. Compared with the method that two electrocardio sensors are connected by hard materials, the method has better adaptability.

As shown in fig. 1, the sensor device for single lead ecg includes: two electrocardio sensors 1 and a cable 2. Two ends of the cable 2 are respectively in signal connection with the two electrocardio sensors 1. The electrocardio-sensor 1 comprises an electrode plate which is attached to a human body. The cable 2 includes a flexible layer in which signal lines are wrapped.

The flexible layer is made of TPU material; giving flexibility to the cable 2. Two electrocardio sensor 1 attach and gather electrocardiosignal in the human body two electrocardio sensor 1 take place when relative displacement, for example when the human body is in motion or breathing, cable 2 has certain pliability and can be crooked, lets two electrocardio sensor 1 keep certain activity space along with the skin elasticity time, thereby reaches the adjustment distance between two sensors.

As described above, the contact distance between the two electrocardiographic sensors 1 on the skin is fixed, and when the skin or muscle shakes, the electrocardiographic sensors 1 are pulled or stretched, and the contact between the electrocardiographic sensors 1 and the skin is displaced relatively, thereby generating motion noise.

Generally, the skin of a human body can generate short-distance displacement along with the motion or respiration of the human body, and after the two electrocardio sensors 1 are attached to the position points of the human body for collecting electrocardiosignals, the two electrocardio sensors 1 naturally also generate displacement along with the skin. Due to certain flexibility of the cable 2, when the two electrocardio sensors 1 move back to back, the cable 2 can pull the two electrocardio sensors 1 to enable the positions of the two electrocardio sensors 1 to be basically unchanged, and accordingly displacement of human skin is resisted.

In addition, the cable 2 is arc-shaped, when the two electrocardio sensors 1 move oppositely, the two electrocardio sensors need to bend the cable 2, and the cable 2 feeds back a counterforce to enable the positions of the two electrocardio sensors 1 to be basically unchanged, so that the displacement of the skin of a human body is resisted. Or at least part of the cable 2 is arc-shaped, as shown in fig. 1, two branch lines at two ends of the cable 2 are connected into the electrocardiograph sensor 1, and most part of the cable is arc-shaped.

Of course, in other embodiments, it is understood that the cable 2 is curved due to gravity, and does not necessarily have to be curved.

The utility model provides a connecting device of single lead electrocardio is on the basis of keeping electrocardio sensor 1 and skin contact mode, improves two electrocardio sensor 1's connection, by dedicated signal transmission line, possesses the function that gets up two electrocardio sensor 1's signal connection on the one hand, and on the other hand can be with on one's body the people of different sizes with same platform equipment adaptation like this, still keeps the in close contact with of electrocardio sensor 1 and skin when the health moves, does not lead to electrocardio sensor 1 atress because of the health moves.

The length of the cable 2 is suitable for people of different body types, so that the two electrocardio sensors 1 can be correctly attached to correct positions of a human body to acquire electrocardiosignals.

It can be understood that a person is tall and short, and the hard cable 2 cannot be well adapted to people of different body types for use, for example, the distance between the position monitored by the electrocardiogram of a fat person is larger than that of the position monitored by the electrocardiogram of a thin person. The flexible cable 2 can be well suitable for people with different body types.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
