Description

Technical Field

[0001] The present invention relates to the technical field of sensor connection structure design and preparation, and in particular to an elastic pleated sensor and a connection structure and a preparation method thereof. Background Art

[0002] A matrix chest ECG electrode fixing device is known from the patent application number CN201611180713.6. The device connects the electrode, elastic band, electrode fixing plate and terminal together through a rivet structure. The whole device has no stretchability and flexibility, and only relies on the pressure of the elastic band to fix the electrode in a fixed position on the body surface, which makes the device poor in anti-motion interference ability and poor wearing comfort.

[0003] Physiological parameter monitoring clothing and methods are learned from the patent with application number CN201811447183.6. This patent mainly improves the signal quality from the aspects of algorithm and signal processing flow. The connection method between the sensor and the body surface still uses the pressure of the tights and the adhesion of the electrode.

[0004] A well-fixed ECG electrode is known from the patent application number CN202123252936.8. The ECG electrode is connected to the body surface by the adhesion of conductive glue. First, the conductive glue still has the possibility of causing human allergies; second, the electrode can only be used once.

[0005] In summary, existing sensors, especially wearable sensors, usually rely on their own adhesion to fix at precise locations on the body surface. However, as the human body moves and sweats during wearing, the adhesion of the sensor will decrease, causing the sensor to fall off during the measurement process. There are also sensors that rely on elastic bands to fix the electrodes at fixed locations on the body surface, but the entire device is not stretchable or bendable. When the elastic band is displaced relative to the body surface during wearing, the sensor on it will also shift accordingly. Summary of the invention

[0006] In order to achieve the above-mentioned purpose and other advantages according to the present invention, the first purpose of the present invention is to provide an elastic pleated sensor connection structure, including: an elastic pleated module, and a plurality of signal transmission lines, the elastic pleated module including a sensor assembly surface, an elastic pleated structure, and a fabric assembly surface arranged in sequence from top to bottom, the signal transmission line is fixed on the pleated surface of the elastic pleated structure, and the signal transmission line is connected to the signal wire end on the fabric.

[0007] Furthermore, the elastic pleated structure includes a hard frame and a textile fabric, and the textile fabric is assembled on the hard frame.

[0008] Furthermore, the rigid frame includes a plurality of brackets and a plurality of connecting members, and the brackets are connected by the connecting members.

[0009] Furthermore, the connecting piece is a spherical structure.

[0010] Furthermore, the elastic pleated structure further comprises an elastic filler, and the elastic filler is filled in the textile fabric;

[0011] The hard frame is made of rigid deformable material.

[0012] Furthermore, the elastic pleated module is a square elastic pleated module, a circular elastic pleated module or a polygonal elastic pleated module.

[0013] Furthermore, the signal transmission line adopts a stretchable shape structure.

[0014] The second object of the present invention is to provide an elastic pleated sensor, comprising an elastic pleated sensor connection structure and a sensor, wherein the sensor is connected to a sensor mounting surface, and the sensor is electrically connected to the signal transmission line.

[0015] A third object of the present invention is to provide a method for manufacturing an elastic wrinkle sensor, comprising the following steps:

[0016] Connecting the fabric assembly surface to the fabric in a close-fitting manner;

[0017] The signal transmission line is tightly attached to the folded surface of the elastic folded structure;

[0018] Connect the signal transmission line to the signal conductor terminal on the fabric;

[0019] Connect the sensor to the sensor assembly surface in a close fit;

[0020] Connect the signal transmission line to the signal lead terminal of the sensor.

[0021] Furthermore, the close-fitting connection of the sensor to the sensor assembly surface includes close-fitting connection of the sensor to the sensor assembly surface by bonding, pin connection, snap connection, barb microstructure hook connection or magnetic connection;

[0022] The step of closely fitting the signal transmission line to the wrinkled surface of the elastic wrinkled structure comprises closely fitting the signal line transmission module to the wrinkled surface of the elastic wrinkled structure by bonding, welding, sewing or hot pressing;

[0023] The step of connecting the signal transmission line to the signal wire end on the fabric includes connecting the signal transmission line to the signal wire end on the fabric by welding or magnetic attraction;

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] The elastic pleated sensor connection structure provided by the present invention has certain support and stretchability, so that after the sensor assembly surface is compressed, it can be more closely attached to the predetermined position on the body surface in combination with the sensor's own adhesion. The elastic pleated sensor connection structure also has certain flexibility, so that when the human body surface and the fabric undergo relative displacement, the sensor on the sensor assembly surface can still be well attached to the original position, thereby enhancing the sensor's ability to resist motion interference. It is particularly important to note that when the elastic pleated sensor connection structure is designed as a cylindrical-like structure, the elastic pleated connection structure has the ability to resist 360° all-round relative displacement between the human body surface and the fabric.

[0027] The elastic pleated sensor connection structure can change its size and shape at will according to the needs of physiological parameter monitoring, and its pleated structure can also change according to the needs of stretchability and support, not only in "Z" shape, but also in arc shape.

[0037] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0038] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0039] Example 1

[0040] An elastic pleated sensor connection structure, such as Figure 1 , Figure 2 As shown, it includes: an elastic pleated module, and several signal transmission lines. The elastic pleated module includes a sensor assembly surface, an elastic pleated structure, and a fabric assembly surface arranged in sequence from top to bottom. Among them, the size and shape of the sensor assembly surface, the elastic pleated structure, and the fabric assembly surface can be customized according to measurement needs. Taking ECG data acquisition as an example, for a single lead electrode, a corresponding square sensor assembly surface, a square elastic pleated structure, and a square fabric assembly surface can be designed. Figure 2As shown, corresponding circular sensor assembly surfaces, circular elastic pleated structures and circular fabric assembly surfaces can also be designed. The circular elastic pleated module design has the ability to resist 360° all-round relative displacement of the antibody surface-fabric. It should be understood that other polygonal sensor assembly surfaces, polygonal elastic pleated structures and polygonal fabric assembly surfaces can also be designed. Sensors of different specifications are closely connected to the sensor assembly surface by bonding, pin connection, snap connection, barb microstructure hook connection, magnetic attraction and other connection methods. It should be particularly noted that the magnetic attraction method can more effectively realize the modular repeated application of the sensor. The sensor is electrically connected to the signal transmission line, the signal transmission line is fixed on the pleated surface of the elastic pleated structure, the signal transmission line is connected to the signal wire end on the fabric, and the fabric assembly surface is closely connected to the fabric by bonding, sewing and other methods. In this embodiment, the signal transmission line is connected to the other surface of the elastic pleated sensor connection structure by bonding, welding, hot pressing, sewing and other methods, and the sensor signal on the sensor assembly surface is transmitted to the fabric assembly surface along the elastic pleated structure. The signal transmission line is connected to the signal wire end on the fabric by welding or other methods. It should be particularly noted that multiple signal transmission lines can be created on each elastic pleated sensor connection structure. When some signal transmission lines are broken during the use of the elastic pleated sensor connection structure, other signal transmission lines can still transmit signals, effectively enhancing the signal transmission life of the elastic pleated sensor connection structure. The shape of the signal transmission line can be a serpentine, "Z" shape, or other stretchable shape structure.

[0041] The elastic pleated module is a square elastic pleated module or a circular elastic pleated module. The elastic pleated sensor connection structure can change the size and shape at will according to the needs of physiological parameter monitoring. Figure 3 , Figure 4 As shown, its elastic pleated structure can also be changed according to the stretchability and support requirements, and can be not only "Z" shaped but also arc shaped.

[0042] The elastic pleated structure includes a hard frame and a textile fabric, and the textile fabric is assembled on the hard frame. Figure 3 As shown, the rigid frame includes a plurality of brackets and a plurality of connectors, and the brackets are connected by the connectors. Preferably, the connector is a spherical structure. The brackets are connected with multiple degrees of freedom by the spherical structure.

[0043] The rigid frame can be made of rigid, deformable materials such as metal or hard plastic. Figure 4 As shown, the hard frame can be blow-molded from a deformable organic material with a certain hardness, such as hard plastic. Figure 5 As shown, the hard frame can be formed by folding a thin layer of material with a certain hardness.

[0044] The number of pleat layers and the pleat height of the elastic pleat structure can also be customized according to the requirements of the sensor measurement. The textile fabric is sewn and assembled to the rigid frame according to the elastic pleat structure. Optionally, the elastic pleat structure is filled with elastic fillings when sewing to provide better comfort and support.

[0045] The elastic pleated sensor connection structure has certain support and stretchability, which allows the sensor assembly surface to be more closely attached to the predetermined position on the body surface after being compressed. The elastic pleated sensor connection structure also has certain flexibility. This allows the sensor on the sensor assembly surface to still be well attached to the original position when the human body surface and the fabric undergo relative displacement, thereby enhancing the sensor's ability to resist motion interference. It is particularly important to note that when the elastic pleated sensor connection structure is designed as a cylindrical-like structure, the elastic pleated sensor connection structure has a 360° all-round ability to resist relative displacement between the human body surface and the fabric.

[0046] The present invention designs an elastic pleated structure connecting block for the sensor and the fabric to prepare a wearable sensor module that can fit closely to the skin, thereby achieving accurate, long-term and real-time collection of healthy physiological parameters of the human body surface.
