Pregnant women special sensor belly belt

Abstract

The present invention discloses a sensor belly belt for pregnant women, comprising a controller, a belly belt body and at least one first piezoelectric film sensor; the belly belt body is elastic; the first piezoelectric film sensor is arranged at the periphery of the belly belt body; the controller is electrically connected to the first piezoelectric film sensor, wherein when the first piezoelectric film sensor detects a signal, the signal flows to the controller. The present invention prevents the piezoelectric film sensor from affecting the stretchability of the belly belt body when the pregnant woman breathes or walks, and also prevents the piezoelectric film sensor from being damaged due to a large-scale pulling of the belly belt body. Moreover, since the periphery of the belly belt body will only be pulled by a small amplitude, the piezoelectric film sensor located at the periphery of the belly belt body will also be pulled by a relatively small amplitude during breathing and exercise, so it can detect the heartbeat, breathing and intestinal peristalsis of the pregnant woman, as well as the fetal movement and fetal heart sound of the fetus, and it is durable and has good experience.

Description

Technical Field

[0001] The invention relates to the field of belly bands, and in particular to a sensor belly band specially used for pregnant women. Background Art

[0002] The belly band is wrapped around the abdomen to support, tighten and fix the abdomen. Before giving birth, the belly band can support the abdomen, prevent uterine prolapse, protect the fetal position and relieve the pressure on the waist of pregnant women. Belly bands include elastic belly bands and inelastic belly bands. In the prior art, inelastic belly bands can be equipped with sensors at any position of the belly band to detect the heartbeat, breathing and other signals of the pregnant woman, as well as the fetal movement, fetal heart sound and other signals; however, since the sensor is inelastic, installing it on the elastic belly band will not only greatly affect the ductility of the belly band, but also easily tear the sensor. Summary of the invention

[0003] The main purpose of the present invention is to provide a sensor belly belt specially designed for pregnant women, aiming to solve the problem in the prior art that the elastic belly belt is affected in its extensibility after a piezoelectric film sensor is installed.

[0004] The present invention provides a sensor belly belt for pregnant women, comprising a controller, a belly belt body and at least one first piezoelectric film sensor;

[0005] The abdominal band body is elastic;

[0006] The first piezoelectric film sensor is arranged on the periphery of the abdominal band body;

[0007] The controller is electrically connected to the first piezoelectric film sensor, wherein when the first piezoelectric film sensor detects a signal, the signal flows to the controller.

[0008] Furthermore, the abdominal band body is made of at least one layer of fabric.

[0009] Furthermore, the first piezoelectric film sensor is arranged on the inner side of the abdominal belt body.

[0010] Furthermore, the belly band body has a thickness of 0.01-1 cm, a length of 20-80 cm, and a width of 10-50 cm.

[0011] Furthermore, the sensor belly belt for pregnant women includes at least four first piezoelectric film sensors, which are evenly distributed around the periphery of the belly belt body to face the edge of the abdomen.

[0012] Furthermore, the sensor belly belt for pregnant women further comprises at least one second piezoelectric film sensor, and the second piezoelectric film sensor is arranged in the middle of the belly belt body to be opposite to the middle part of the abdomen;

[0013] The controller is electrically connected to the second piezoelectric film sensor, wherein when the second piezoelectric film sensor detects a signal, the signal flows to the controller.

[0014] Furthermore, a clearance hole is formed in the middle of the belly band body to allow the navel to pass through, and the second piezoelectric film sensor is arranged around the clearance hole.

[0015] Furthermore, the sensor belly belt for pregnant women also includes a plurality of first wires and a plurality of second wires;

[0016] The first piezoelectric film sensor is electrically connected to the controller through the first wire, so that when the first piezoelectric film sensor detects a signal, the signal flows to the controller through the first wire;

[0017] The second piezoelectric film sensor is electrically connected to the controller through the second wire, so that when the first piezoelectric film sensor detects a signal, the signal flows to the controller through the second wire.

[0018] Furthermore, the sensor belly belt for pregnant women also includes a fixing component, and the fixing component is connected to the belly belt body to wrap the belly belt body around the abdomen.

[0019] Further, the fixing assembly includes a first connecting belt and a second connecting belt;

[0020] One end of the first connecting belt is connected to one end of the abdominal belt body, the other end of the first connecting belt is connected to one end of the second connecting belt, and the other end of the second connecting belt is connected to the other end of the abdominal belt body.

[0021] Beneficial effects of the present invention: the abdomen of a pregnant woman is roughly hemispherical. When the pregnant woman breathes or exercises, the edge of the abdomen and the area around the navel will hardly stretch. When the belly band body is wrapped around the abdomen, the edge of the belly band body is tightly attached to the edge of the abdomen, and the middle part of the belly band body is tightly attached to the middle position of the abdomen (the middle position of the abdomen is the navel and the area around the navel). Since the edge of the abdomen hardly stretches, the edge of the belly band body will only be pulled relatively slightly during breathing and exercise, and will hardly stretch. After the piezoelectric film sensor with almost no elasticity is arranged on the edge of the belly band body, the piezoelectric film sensor can be prevented from affecting the stretchability of the belly band body, and the piezoelectric film sensor can be prevented from being damaged by a large pull of the belly band body. Moreover, since the edge of the belly band body will only be pulled very slightly, the piezoelectric film sensor located on the edge of the belly band body will also be pulled very slightly. Therefore, it can detect signals such as the heartbeat, breathing and intestinal peristalsis of the pregnant woman, as well as signals such as fetal movement and fetal heart sound, and it is durable and has the characteristics of good experience.

[0028] See also Figure 1-2 An embodiment of the present invention provides a sensor belly belt for pregnant women, including a controller 60, a belly belt body 20 and at least one first piezoelectric film sensor 101, the belly belt body 20 is elastic; the first piezoelectric film sensor 101 is arranged on the periphery of the belly belt body 20; the controller 60 is electrically connected to the first piezoelectric film sensor 101, wherein when the first piezoelectric film sensor 101 detects a signal, the signal flows to the controller 60.

[0029] In this embodiment, the abdomen of a pregnant woman is roughly hemispherical. When the pregnant woman breathes or exercises, the edge of the abdomen and the area around the navel will hardly stretch. When the belly band body 20 is wrapped around the abdomen, the edge of the belly band body 20 is tightly attached to the edge of the abdomen, and the middle of the belly band body 20 is tightly attached to the middle part of the abdomen (the middle part of the abdomen is the navel and the area around the navel). Since the edge of the abdomen will hardly stretch, the edge of the belly band body 20 will only be pulled relatively slightly during breathing and exercise, and will hardly stretch, and will have almost no elasticity. After the piezoelectric film sensor is arranged at the periphery of the belly band body 20, the piezoelectric film sensor can be prevented from affecting the stretchability of the belly band body 20, and the belly band body 20 can be prevented from being pulled greatly and causing damage to the piezoelectric film sensor. Moreover, since the periphery of the belly band body 20 will only be pulled very slightly, the piezoelectric film sensor located at the periphery of the belly band body 20 will also be pulled very slightly. Therefore, it can detect signals such as the heartbeat, breathing, intestinal peristalsis of pregnant women, as well as signals such as fetal movement and fetal heart sounds, and it is durable and provides a good experience.

[0030] The piezoelectric film sensor is a dynamic strain sensor made of piezoelectric film, which can be applied to the surface of human skin or implanted inside the human body. When the piezoelectric film sensor is stretched or bent, the piezoelectric film sensor can detect the physiological signals of the human body. Therefore, in this embodiment, a piezoelectric film sensor is used to detect the physiological signals of pregnant women on the belly band.

[0031] In this embodiment, the controller 60 is used to receive and process the physiological signals of the pregnant woman detected by the piezoelectric film sensor. A conventional controller 60 can be used. For example, in an optional embodiment, the controller 60 includes an amplifier circuit 601, a filter 602, an analog / digital conversion circuit 603, a DSP module 604, a memory 605 and an interface module 606. The piezoelectric film sensor is electrically connected to the amplifier circuit 601, the amplifier circuit 601 is electrically connected to the filter 602, the filter 602 is electrically connected to the analog / digital conversion circuit 603, the analog / digital conversion circuit 603 is electrically connected to the DSP module 604, and the DSP module 604 is electrically connected to the memory 605 and the interface module 606. When the piezoelectric film sensor detects the physiological signal of the pregnant woman, it sends the physiological signal to the controller 60. The physiological signal of the pregnant woman passes through the amplifier circuit 601 and the filter 602 in sequence and then enters the DSP module 604. The DSP module 604 processes the physiological signal of the pregnant woman to obtain the heartbeat, breathing, intestinal peristalsis and other signals of the pregnant woman, as well as the fetal movement and fetal heart sound and other signals. The DSP module 604 sends the obtained heartbeat, breathing, intestinal peristalsis and other signals of the pregnant woman, as well as the fetal movement and fetal heart sound and other signals to the memory 605 and the interface module 606. The memory 605 stores the heartbeat, breathing, intestinal peristalsis and other signals of the pregnant woman, as well as the fetal movement and fetal heart sound and other signals. The interface module 606 can be electrically connected to the display screen to display the heartbeat, breathing, intestinal peristalsis and other signals of the pregnant woman, as well as the fetal movement and fetal heart sound and other signals on the display screen in the form of images or text. The interface module 606 can also be connected to the wireless communication module to send the heartbeat, breathing, intestinal peristalsis and other signals of the pregnant woman, as well as the fetal movement and fetal heart sound and other signals to the user terminal through the wireless communication module.

[0032] In this embodiment, the number of the first piezoelectric film sensors 101 is not limited and can be set as needed. For example, it can be one, two, four, eight or sixteen. When there are more than two first piezoelectric film sensors 101, they are evenly distributed around the periphery of the abdominal band body 20.

[0033] In this embodiment, the controller 60 may be disposed on the belly band body 20, for example, at the end of the belly band body 20, or may be disposed at other positions that are convenient for operation.

[0034] In this embodiment, when the first piezoelectric film sensor 101 detects a signal, the signal flows to the controller 60 , which can be understood as: the controller 60 acquires the signal detected by the first piezoelectric film sensor 101 .

[0035] In another embodiment of the present invention, the belly band body 20 is made of at least one layer of fabric. The number of fabric layers is not limited and can be set according to needs. For example, it can be one layer, two layers, four layers, eight layers or sixteen layers. The fabric can be made of materials such as polyester or nylon. A layer of fabric can be made of one-piece molding or can be made of several small pieces of fabric spliced ​​together. When a layer of fabric is made of one-piece molding, it can be composited with one or more materials. When a layer of fabric is made of several small pieces of fabric spliced ​​together, each small piece of fabric can also be composited with one or more materials. For example, in a specific embodiment, the belly band body 20 includes two layers of fabric, and the two layers of fabric are arranged in a close relationship. The first layer of fabric is made of nylon material and is made of two small pieces of fabric spliced ​​together. The second layer of fabric is made of two small pieces of fabric spliced ​​together. One small piece of fabric is made of polyester material, and the other small piece of fabric is made of polyester material and nylon material.

[0036] Furthermore, the first piezoelectric film sensor 101 is disposed on the inner side of the belly band body 20 and is attached to the belly band body 20 , so that the sensitivity of the first piezoelectric film sensor 101 is better.

[0037] Furthermore, the belly band body 20 has a thickness of 0.01-1 cm, a length of 20-80 cm, and a width of 10-50 cm, so as to maximize the comfort of the belly band body 20. In this embodiment, the belly band body 20 may be square or round, or may be irregular in shape. In this embodiment, the length direction of the belly band body 20 is the direction toward the two waists when the belly band body 20 is wrapped around the abdomen; the width direction of the belly band body 20 is the direction toward the chest and pelvis when the belly band body 20 is wrapped around the abdomen.

[0038] In another embodiment of the present invention, the sensing belly belt for pregnant women includes at least four first piezoelectric film sensors 101, which are evenly distributed on the periphery of the belly belt body 20 to face the edge of the abdomen. For example, when the belly belt body 20 is in the shape of a rectangular parallelepiped and there are four first piezoelectric film sensors 101, the four first piezoelectric film sensors 101 are respectively arranged on the four corners of the belly belt body 20. It should be understood that when the belly belt body 20 is in the shape of a rectangular parallelepiped and there are eight first piezoelectric film sensors 101, the eight first piezoelectric film sensors 101 can also be evenly distributed on the four corners of the belly belt body 20, with two first piezoelectric film sensors 101 arranged at each corner. Arranging the first piezoelectric film sensors 101 at the corners of the belly belt body 20 can not only prevent the first piezoelectric film sensors 101 from affecting the stretchability of the belly belt body 20, but also detect more physiological signals of pregnant women.

[0039] In another embodiment of the present invention, the sensing belly belt for pregnant women includes at least one second piezoelectric film sensor 102, which is arranged in the middle of the belly belt body 20 to be opposite to the middle part of the abdomen; the controller 60 is electrically connected to the second piezoelectric film sensor 102, wherein when the second piezoelectric film sensor 102 detects a signal, the signal flows to the controller 60.

[0040] After the belly band body 20 is wrapped around the abdomen, the middle of the belly band body 20 corresponds to the navel and the sides around the navel. Because the sides around the navel are almost not stretched when pregnant women breathe or exercise, the second piezoelectric film sensor 102 is arranged in the middle of the belly band body 20, which can also prevent the second piezoelectric film sensor 102 from affecting the stretchability of the belly band body 20 when pregnant women breathe or exercise, and can also prevent the belly band body 20 from being pulled greatly and causing the second piezoelectric film sensor 102 to be damaged.

[0041] Furthermore, a clearance hole 30 is formed in the middle of the belly band body 20 to allow the navel to pass through, and the second piezoelectric film sensor 102 is arranged around the clearance hole 30. Since the navels of most pregnant women are convex, the middle of the belly band body 20 is hollowed out to form the clearance hole 30 so that the navel can pass through the clearance hole 30, thereby increasing the comfort of the belly band. It should be understood that when there are multiple second piezoelectric film sensors 102, they can be evenly distributed around the clearance hole 30.

[0042] In this embodiment, when the second piezoelectric film sensor 102 detects a signal, the signal flows to the controller 60, which can be understood as: the controller 60 obtains the signal detected by the second piezoelectric film sensor 102.

[0043] In another embodiment of the present invention, the sensor belly belt for pregnant women also includes a plurality of first wires and a plurality of second wires; the first piezoelectric film sensor 101 is electrically connected to the controller 60 through the first wires, so that when the first piezoelectric film sensor 101 detects a signal, the signal flows to the controller 60 through the first wires; the second piezoelectric film sensor 102 is electrically connected to the controller 60 through the second wires, so that when the first piezoelectric film sensor 101 detects a signal, the signal flows to the controller 60 through the second wires.

[0044] Furthermore, the first conductive wire and the second conductive wire are arranged at the ends of the belly band body 20 to prevent the first conductive wire and the second conductive wire from affecting the stretchability of the belly band body 20 .

[0045] Furthermore, the first wire and the second wire use stretchable spring wires to further prevent the first wire and the second wire from affecting the stretchability of the belly band body 20. For example, when the second wire is connected to the second piezoelectric film sensor 102, part of the second wire needs to be arranged on the surface of the belly band body 20. When the spring wire is used as the wire, both the belly band body 20 and the second wire can be stretched, which can effectively prevent the second wire from affecting the stretchability of the belly band body 20 when the belly band body 20 is stretched.

[0046] In another embodiment of the present invention, the sensor belt for pregnant women further comprises a fixing assembly, which is connected to the belt body 20 to wrap the belt body 20 around the abdomen. For ease of use, the controller 60 can be mounted on the fixing assembly.

[0047] Further, the fixing assembly includes a first connecting belt 40 and a second connecting belt 50; one end of the first connecting belt 40 is connected to one end of the belly band body 20, the other end of the first connecting belt 40 is connected to one end of the second connecting belt 50, and the other end of the second connecting belt 50 is connected to the other end of the belly band body 20. The belly band body 20 can be wrapped around the abdomen through the first connecting belt 40 and the second connecting belt 50 so that the piezoelectric film sensor can detect the physiological signal of the pregnant woman. Velcro can be set on the first connecting belt 40 and the second connecting belt 50, and the first connecting belt 40 and the second connecting belt 50 are connected by Velcro to facilitate wearing the belly band. In other embodiments, the fixing assembly can also include only one fixing section, one end of the fixing section is fixedly connected to one end of the belly band body 20, the other end of the fixing section and the other end of the belly band body 20 have Velcro, and the other end of the fixing section is connected to the other end of the belly band body 20 by Velcro.

[0048] In the present application, the piezoelectric film sensor includes a first piezoelectric film sensor 101 and a second piezoelectric film sensor 102. When there are more than two piezoelectric film sensors, each piezoelectric film sensor independently detects the physiological signals of the pregnant woman, and the controller 60 processes each physiological signal of the pregnant woman according to the order in which the physiological signals of the pregnant woman are received. The piezoelectric film sensors can detect different physiological signals of the pregnant woman respectively according to the different positions of arrangement, or can jointly detect a physiological signal of the pregnant woman. For example, when there are four piezoelectric film sensors, the piezoelectric film sensors are respectively arranged on the four corners of the belly band body 20. The four piezoelectric film sensors can respectively detect the heartbeat signal of the pregnant woman, the breathing signal of the pregnant woman, the fetal movement signal of the fetus, and the fetal heart sound signal of the fetus. The four piezoelectric film sensors can also only detect the fetal movement signal of the fetus. The specific setting can be selected according to the specific situation.

[0049] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
