Description

Technical Field

[0001] The present invention relates to the technical field of wearable devices, and specifically relates to a wearable device for continuous monitoring of physiological parameters during pregnancy. Background Art

[0002] During pregnancy, due to inconvenient movement, pregnant women cannot go to the hospital at any time. Moreover, in the late pregnancy, due to the increase in fetal movement, if they go to the hospital every time fetal movement occurs, the pregnant women will be very tired from the round trip and there are risks. Therefore, being able to monitor by themselves during pregnancy and continuously monitor the physiological parameters of pregnant women and fetuses in real time is the key to preventing pregnancy complications and ensuring the health of mothers and babies. Although existing wearable devices can provide certain monitoring functions, there are still many defects. For example, traditional devices use a rigid structure or a fixed strap design and cannot adapt to the dynamic changes of a pregnant woman's abdomen as the gestational week increases. Another example is that some devices use an intermittent monitoring mode, or due to unreasonable sensor layout, such as single-contact acquisition, which easily leads to data interruption.

[0003] Therefore, the prior art has proposed many technologies suitable for pregnant women to wear and monitor. For example, the prior art IN202541037443 discloses a wearable pregnant woman support and assistance device for prenatal care and pregnant woman-fetus monitoring. The device specifically includes: a frame composed of curved members and having an annular band worn on the shoulders of a pregnant user; a flexible band connected to the band for supporting the spinal region; and the device also has a health monitoring module, which analyzes the health and activities of the user, a piezometric element for detecting the weight of the user's abdomen, and a fetal monitoring unit for analyzing the health of the fetus. Another example is the prior art IN202541039600, which discloses a wearable safety and injury prevention device that can provide physical protection for the wearing user and can play a certain protective effect on pregnant women. However, the existing technologies still have room for improvement in terms of flexible fitting for pregnant women to wear, reducing wearing discomfort, and obtaining continuous physiological parameters. Summary of the Invention

[0004] The purpose of the present invention is to provide a wearable device for continuous monitoring of physiological parameters during pregnancy, which can flexibly fit the user during wearing, continuously monitor the physiological parameters during pregnancy and can adapt to the dynamic changes of a pregnant woman's abdomen, so as to solve problems such as uncomfortable wearing and easy interruption of monitoring data of existing devices.

[0005] To solve the above technical problems, the present invention specifically provides the following technical solutions: A wearable device for continuous monitoring of physiological parameters during pregnancy, including a first base body. On one side of the first base body, there is a monitoring component, and on the other side, there is a back plate component. The monitoring component includes a bottom plate, and a first monitor and a second monitor are connected to the bottom plate. The back plate component has a main control chip connected to the first monitor and the second monitor; the second monitor clamps the finger of the pregnant woman, and the first monitor is attached to the position of the pregnant woman's abdomen or heart. When attached to the abdomen, it is flexibly wrapped by a first strap and a second strap on the outside.

[0006] The bottom plate has a first strap detachably connected to the bottom plate and a second strap detachably connected to the bottom plate. The first strap and the second strap are connected to the bottom plate by means of Velcro.

[0007] The first strap and the second strap can form an upward lifting force on the bottom of the pregnant woman's abdomen, reducing the daily discomfort of the pregnant woman, and having effects such as external protection and sun protection on the pregnant woman's abdomen.

[0008] Through the first monitor and the second monitor on the bottom plate of the monitoring component provided on one side of the first base body of the present invention, and the main control chip of the back plate component, physiological parameters such as heart rate and uterine contractions can be continuously collected and processed in real time; the first strap and the second strap detachably connected to the bottom plate by Velcro can flexibly adjust the tightness according to the dynamic changes of the pregnant woman's abdomen, making the first base body fit flexibly with the back of the pregnant woman, which not only solves the problem of uncomfortable wearing of the existing device, but also avoids the interruption of monitoring data through a stable fitting state, realizing reliable continuous monitoring of physiological parameters during pregnancy.

[0009] According to an embodiment of the present invention, both ends of the first strap are respectively connected to the bottom plate and form a circular state with the bottom plate. The second strap is arranged on the inner side surface of the first strap. The first strap and the second strap are made of medical elastic silicone or breathable elastic fabric. The design that both ends of the first strap are connected to the bottom plate to form a circular structure and the second strap is arranged on the inner side surface of the first strap provides a basic fixed support for the device through the circular first strap, can form a stable wearing state around the lower position of the pregnant woman's abdomen, and the second strap on the inner side surface can be closer to the abdomen. The two cooperate to form a double-layer support and lift under the pregnant woman's abdomen, which not only enhances the stability of the device wearing, but also can adapt to the dynamic changes of the abdomen through the flexible adjustment of the double-layer strap, improving the fitting degree and comfort during wearing. The tightness can be adjusted by the user according to their own needs, but it is necessary to ensure that the monitoring component is in stable contact with the abdomen to ensure the continuity and reliability of physiological parameter monitoring.

[0010] According to an embodiment of the present invention, the first strap and the second strap are parallel to each other and have a spacing therebetween. The surface of the second strap is arrayed and attached with flexible bottom plates, and flexible support strips are arranged at intervals on the surface of the flexible bottom plates. The ends of the flexible support strips are connected to the side surface of the first strap. The design that the first strap and the second strap are parallel to each other and maintain a spacing forms a stable support and lifting framework through a double-layer strap structure, which can evenly disperse the pressure of the device on the pregnant woman's abdomen. The flexible bottom plates arrayed and attached to the surface of the second strap utilize the deformation ability of the flexible material to improve the fit with the abdomen. And the flexible support strips arranged at intervals on the surface of the flexible bottom plates, after their ends are connected to the side surface of the first strap, can form an elastic buffer structure when the straps are stressed. It can not only prevent the straps from being overly deformed through the support strips, but also utilize the flexible material to adapt to the dynamic undulation of the abdomen. While ensuring the stability of the device wearing, through the synchronous action of the flexible bottom plates and the support strips, it can reduce the sense of compression on the pregnant woman's abdomen, improve the comfort of long-term wearing, and can always maintain stable contact between the monitoring component and the skin, ensuring the continuity and reliability of the physiological parameter monitoring data.

[0011] According to an embodiment of the present invention, both the first monitor and the second monitor are connected to the main control chip through line connectors. The physiological parameters collected by the first monitor at the position of the pregnant woman's belly or heart, such as pressure, temperature, bioelectric signals, etc., and the parameters obtained by the second monitor clamping the pregnant woman's finger, such as heart rate, blood oxygen, etc., can be stably transmitted to the main control chip in the backplane assembly through the line connectors.

[0012] According to an embodiment of the present invention, a filling component is provided on the side surface of the bottom plate. The filling component includes a filling matrix, and the filling matrix is a plate structure with a hollow interior. A first spring is arranged in the space inside the filling matrix. The filling component provided on the side surface of the bottom plate can reduce the overall weight through the hollow structure, and at the same time utilize the elastic deformation ability of the first spring to form a buffer support when the filling component contacts the back or waist of the pregnant woman. When the pregnant woman sits down or moves, the first spring can be compressed or rebounded adaptively, so that the filling matrix closely fits the curve of the back or waist of the pregnant woman. It can not only reduce the rigid compression on the back or waist of the pregnant woman, improve the wearing comfort and relieve the fatigue of the waist or back, but also ensure that the monitoring component maintains stable contact with the skin, avoiding the interruption of the monitoring data caused by the change of body position, and realizing the continuous and reliable collection of physiological parameters during pregnancy.

[0013] According to one embodiment of the present invention, the thickness of the lower part of the filling matrix is thicker than that of the upper part, and at least two first through holes are provided on the surface of the filling matrix. A first groove is provided at the bottom of the surface of the filling matrix. The lower thickening design can specifically enhance the support effect on the back or waist of pregnant women, adapt to the physiological characteristics of the abdominal protrusion in late pregnancy, and reduce the pressure and discomfort caused by falling; the first through hole runs through the surface of the filling matrix to form an air convection channel, reduce the stuffiness of the skin when worn for a long time, and improve wearing comfort; the first groove at the bottom uses the structural deformation space and the elastic buffer of the internal first spring to enable the filling matrix to bend adaptively, avoiding the monitoring position offset caused by rigid contact, thereby ensuring the stable fit of the monitoring component to the skin and ensuring the continuity and reliability of physiological parameter collection.

[0014] According to one embodiment of the present invention, first straps are provided on both sides of the first base, each with a fastener. The fasteners' quick-connect mechanism allows for convenient donning and removal, meeting emergency needs. The first straps, combined with the fasteners, can be flexibly adjusted to the pregnant woman's body size, ensuring a stable fit for the first base and the pregnant woman's torso.

[0015] According to one embodiment of the present invention, the main control chip is mounted on the backplane body, and the backplane body is arranged on the side of the first substrate away from the monitoring component. The monitoring component has a first monitor and a second monitor, so that it can collect physiological signals in real time close to the abdomen or heart of the pregnant woman. The signal is transmitted to the main control chip in the backplane body through the line connector to achieve real-time amplification, filtering and analog-to-digital conversion of the data. The layout position of the backplane body can utilize the flexible structure of the first substrate to evenly distribute the weight of the chip on the back, reducing the pressure on the abdomen. Furthermore, the main control chip is kept away from the skin contact side to facilitate heat dissipation and circuit maintenance.

[0016] According to one embodiment of the present invention, the first monitor includes at least one of a pressure sensor, a temperature sensor, and a biopotential electrode. The second monitor includes at least one of a pressure sensor, a temperature sensor, and a biopotential electrode.

[0017] The first and second monitors each integrate at least one of a pressure sensor, a temperature sensor, and a biopotential electrode, forming a multi-parameter monitoring system. When the first monitor is placed against a pregnant woman's belly or heart, it uses the pressure sensor to capture fluctuations in uterine contraction pressure, the temperature sensor to track changes in skin temperature, and the biopotential electrodes to collect ECG signals, accurately reflecting fetal activity and the pregnant woman's heart function. When the second monitor is placed against a finger, it uses the pressure / temperature sensor or biopotential electrodes to obtain basic vital signs data such as heart rate and blood oxygen. Combined with the real-time processing capabilities of the main control chip, this can effectively warn of pregnancy complications and provide reliable data support for pregnancy health management.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The wearable device for continuous monitoring of physiological parameters during pregnancy of the present invention can continuously and real-time collect and process physiological parameters such as heart rate and uterine contractions through the first monitor and the second monitor on the bottom plate of the monitoring component provided on one side of the first base body, and the main control chip of the back plate component, solving the problem of data interruption caused by the intermittent monitoring mode or unreasonable sensor layout of the existing devices. The first strap and the second strap detachably connected to the bottom plate with Velcro can flexibly adjust the tightness according to the dynamic changes of the pregnant woman's abdomen, enabling the first base body to fit flexibly with the back of the pregnant woman, solving the problem that the existing devices with rigid structures or fixed strap designs cannot adapt to the dynamic changes of the pregnant woman's abdomen as the gestational week increases, not only solving the problem of uncomfortable wearing of the existing devices, but also avoiding data interruption of monitoring through a stable fitting state, realizing reliable and continuous monitoring of physiological parameters during pregnancy.

Detailed implementation manners

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] First, the concepts involved in the present application will be described with reference to the accompanying drawings. It should be noted here that the descriptions of the following concepts are only for making the content of the present application easier to understand, and do not represent a limitation on the protection scope of the present application; at the same time, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0024] Embodiment 1: As shown in the attached Figure 1 - attached Figure 7 figure, the present invention provides a wearable device for continuously monitoring physiological parameters during pregnancy, including a first base body 10. A monitoring assembly 30 is provided on one side of the first base body 10, and a back plate assembly 20 is provided on the other side. The monitoring assembly 30 includes a bottom plate, and a first monitor 34 and a second monitor 33 are connected to the bottom plate. The back plate assembly 20 has a main control chip connected to the first monitor 34 and the second monitor 33; the second monitor 33 clamps the finger of the pregnant woman, and the first monitor 34 is attached to the belly or heart position of the pregnant woman. When attached to the belly, the outside is flexibly wrapped by a first strap 31 and a second strap 32.

[0025] The bottom plate has a first strap 31 detachably connected to the bottom plate and a second strap 32 detachably connected to the bottom plate. The first strap 31 and the second strap 32 are connected to the bottom plate by means of Velcro.

[0026] The first strap 31 and the second strap 32 can form an upward supporting force on the bottom of the belly of the pregnant woman, reduce the daily discomfort of the pregnant woman, and play an external protection and sunscreen effect on the belly of the pregnant woman.

[0027] Through the first monitor 34 and the second monitor 33 on the bottom plate of the monitoring component 30 provided on one side of the first base body 10 and the main control chip of the back plate component 20, the present invention can continuously collect and process physiological parameters such as heart rate and uterine contractions in real time; the first strap 31 and the second strap 32 detachably connected to the bottom plate with Velcro can flexibly adjust the tightness according to the dynamic changes of the pregnant woman's abdomen, so that the first base body 10 fits flexibly with the back of the pregnant woman, which not only solves the problem of uncomfortable wearing of existing devices, but also avoids interruption of monitoring data through a stable fitting state, realizing reliable and continuous monitoring of physiological parameters during pregnancy.

[0028] See the appendix Figure 3 As shown, both ends of the first strap 31 are respectively connected to the bottom plate and form a circular state with the bottom plate. The first strap 31 and the second strap 32 are made of medical elastic silica gel or breathable elastic fabric. The second strap 32 is arranged on the inner side surface of the first strap 31. Both ends of the first strap 31 are connected to the bottom plate to form a circular structure. The first strap 31 and the second strap 32 are parallel to each other and have a spacing therebetween. The surface of the second strap 32 is arrayed and attached with a flexible bottom plate 36. The surface of the flexible bottom plate 36 is provided with flexible support strips 37 at intervals. The end of the flexible support strip 37 is connected to the side surface of the first strap 31. The design that the second strap 32 is arranged on the inner side surface of the first strap 31 provides a basic fixed support for the device through the circular first strap 31, and can form a stable wearing state around the lower position of the pregnant woman's abdomen. The second strap 32 on the inner side surface can be closer to the abdomen. The cooperation of the two enables the device to form a double-layer support under the lower position of the pregnant woman's abdomen, which not only enhances the stability of the device wearing, but also can adapt to the dynamic changes of the abdomen through the flexible adjustment of the double-layer straps, improving the fitting degree and comfort during wearing. The tightness can be adjusted by the user according to their own needs, but it is necessary to ensure that the monitoring component 30 is in stable contact with the abdomen to ensure the continuity and reliability of physiological parameter monitoring.

[0029] The design that the first strap 31 and the second strap 32 are parallel to each other and maintain a spacing forms a stable support and lifting frame through the double-layer strap structure, which can evenly disperse the pressure of the device on the pregnant woman's abdomen. The flexible bottom plate 36 arrayed and attached to the surface of the second strap 32 utilizes the deformation ability of the flexible material to improve the fitting degree with the abdomen. The flexible support strips 37 arranged at intervals on the surface of the flexible bottom plate 36, after their ends are connected to the side surface of the first strap 31, can form an elastic buffer structure when the strap is stressed, which can not only prevent the strap from being overly deformed through the support strip 37, but also utilize the flexible material to adapt to the dynamic undulation of the abdomen. While ensuring the wearing stability of the device, through the synchronous action of the flexible bottom plate 36 and the support strip 37, the compression feeling on the pregnant woman's abdomen can be reduced, the comfort during long-term wearing can be improved, and the stable contact between the monitoring component 30 and the skin can be maintained all the time to ensure the continuity and reliability of physiological parameter monitoring data.

[0030] Both the first monitor 34 and the second monitor 33 are connected to the main control chip through the line connector 35. The physiological parameters collected by the first monitor 34 at the position of the pregnant woman's abdomen or heart, such as pressure, temperature, bioelectric signals, etc., and the parameters obtained by the second monitor 33 by clamping the pregnant woman's finger, such as heart rate, blood oxygen, etc., can be stably transmitted to the main control chip in the backplane assembly 20 through the line connector 35.

[0031] See the appendix Figure 4 As shown, the side of the bottom plate has a filling component 40. The filling component 40 includes a filling matrix 41. The filling matrix 41 is a plate structure with a hollow interior. A first spring 46 is arranged in the space inside the filling matrix 41. The filling component 40 arranged on the side of the bottom plate can reduce the overall weight through the hollow structure. At the same time, by using the elastic deformation ability of the first spring 46, a buffer support is formed when the filling component 40 contacts the back or waist of the pregnant woman. When the pregnant woman sits down or moves, the first spring 46 can be compressed or rebounded adaptively, so that the filling matrix 41 closely fits the back or waist curve of the pregnant woman. It can not only reduce the rigid pressure on the back or waist of the pregnant woman, improve the wearing comfort and relieve the fatigue of the waist or back, but also ensure that the monitoring component 30 is in stable contact with the skin, avoid the interruption of monitoring data caused by postural changes, and realize the continuous and reliable collection of physiological parameters during pregnancy.

[0032] The lower part of the filling matrix 41 is thicker than the upper part, and at least two first through holes 42 are opened on the surface of the filling matrix 41. There is a first groove 43 at the bottom of the surface of the filling matrix 41. The design of increasing the thickness of the lower part can specifically enhance the supporting effect on the back or waist of the pregnant woman, adapt to the physiological characteristics of the anterior protrusion of the abdomen in the late pregnancy, and reduce the sense of oppression and discomfort caused by sagging; the first through holes 42 penetrate the surface of the filling matrix 41 to form an air convection channel, reduce the stuffy feeling of the skin during long-term wearing, and improve the wearing comfort; the first groove 43 at the bottom can, through the structural deformation space, cooperate with the elastic buffer of the internal first spring 46, make the filling matrix 41 bend adaptively, avoid the deviation of the monitoring position caused by rigid contact, so as to ensure the stable fitting of the monitoring component 30 and the skin, and ensure the continuity and reliability of the collection of physiological parameters.

[0033] See the appendix Figure 7 As shown, first straps 12 are arranged on both sides of the first base body 10, and buckle parts 16 are provided on the first straps 12. Through the quick clamping structure of the buckle parts 16, convenient wearing and disassembly can be realized to meet the use requirements in emergency situations. The first straps 12 cooperate with the buckle parts 16 to flexibly adjust the wearing effect according to the body size of the pregnant woman, so that the first base body 10 and the pregnant woman's body form a stable wearing state.

[0034] The main control chip is installed on the backplane body 22, and the backplane body 22 is arranged on the side of the first base body 10 facing away from the monitoring component 30. The monitoring component 30 has a first monitor 34 and a second monitor 33, which can collect physiological signals in real time close to the pregnant woman's abdomen or heart position. The signals are transmitted to the main control chip in the backplane body 22 through the line connector 35 to realize real-time amplification, filtering and analog-to-digital conversion of the data. The layout position of the backplane body 22 can use the flexible structure of the first base body 10 to evenly disperse the weight of the chip on the back, reducing the pressure on the abdomen. Further, the main control chip is far from the skin contact side, which is convenient for heat dissipation and circuit maintenance.

[0035] The first monitor 34 includes at least one of a pressure sensor, a temperature sensor, and a bioelectric electrode. The second monitor 33 includes at least one of a pressure sensor, a temperature sensor, and a bioelectric electrode.

[0036] The first monitor 34 and the second monitor 33 are respectively integrated with at least one of a pressure sensor, a temperature sensor, and a bioelectric electrode to form multi-parameter monitoring: when the first monitor 34 is attached to the pregnant woman's belly or heart position, the contraction pressure fluctuation can be captured by the pressure sensor, the skin temperature change can be tracked by the temperature sensor, and the electrocardiogram signal can be collected by the bioelectric electrode, accurately reflecting the fetal activity and the pregnant woman's heart function; when the second monitor 33 clamps the finger, basic vital sign data such as heart rate and blood oxygen can be obtained by using the pressure / temperature sensor or the bioelectric electrode. With the real-time processing ability of the main control chip, pregnancy complications can be effectively warned, providing reliable data support for prenatal health management.

[0037] Embodiment 2: Compared with the solution of Embodiment 1, this embodiment provides another solution for the filling component 40. Specifically, as shown in the attached Figure 5 figure, the surface of the filling base body 41 used to contact the user in this embodiment has first protrusions 44, and the first protrusions 44 are evenly distributed on the surface of the filling base body 41. There is a spacing between adjacent first protrusions 44, which can still leave a channel for air flow after contacting the user's back or waist, contributing to heat dissipation.

[0038] A magic tape is used on the first groove 43 to stick the flexible cushion plate 45, which is used to fill the gap between the user and ensure the support contact effect, improving the comfort of the user's waist.

[0039] By filling the first protrusions 44 evenly distributed on the surface of the substrate 41 and the spacing between the first protrusions 44, an air flow passage is formed, which can promote air convection when contacting the user's back or waist, effectively reduce the stuffy feeling during long-term wearing, and improve the wearing comfort. At the same time, the flexible cushion plate 45 fastened on the first groove 43 by the magic tape can adaptively fill the gap between the device and the user's body, reduce the rigid contact through the buffering effect of the flexible cushion plate 45, and cooperate with the support structure of the first protrusions 44 to ensure the stable fitting of the monitoring component 30 with the skin, and avoid the sense of compression by optimizing the breathability and buffering performance of the contact interface.

[0040] Embodiment 3: Compared with the solution of Embodiment 1, the further solution provided in this embodiment is as follows. Refer to the attached Figure 6 As shown, there are first side plates 11 on both sides of the first substrate 10. The first side plates 11 can swing or rotate relative to the first substrate 10. The side surface of the first substrate 10 has an outward protruding cylinder, and the first side plates 11 have insertion rods that are inserted into and can rotate with the outward protruding cylinder. The end of the flexible round block has a flexible edge, and the diameter of the flexible round block with the flexible edge is larger than the diameter of the through hole. The first side plates 11 on both sides of the first substrate 10 achieve relative swinging or rotation through the insertion structure of the outward protruding cylinder and the insertion rod, and cooperate with the fixed connection of the connecting block plate 14 and the back plate body 22, so that the back plate assembly 20 can adaptively adjust the angle with the deformation of the first substrate 10 and accurately fit the dynamic undulation of the pregnant woman's abdomen.

[0041] The surface of the first side plate 11 is connected to the back plate body 22 through the connecting block plate 14. The connecting block plate 14 is provided with a through hole. The surface of the connecting block plate 14 and the back plate body 22 are fixedly connected, or they can be integrally formed. The surface of the first side plate 11 has a flexible round block that can pass through the through hole of the connecting block plate 14. The flexible round block on the surface of the first side plate 11 is clamped to the connecting block plate 14 through a flexible edge with a diameter larger than the through hole, which not only ensures the connection stability of the back plate assembly 20, but also allows a certain amount of elastic displacement to buffer the pulling force during movement.

[0042] The side edge of the first substrate 10 has a flexible connecting plate 13. The flexible connecting plate 13 is fixedly connected to the first substrate 10, and specifically, the two are connected by a sewing connection method. The flexible connecting plate 13 is a sponge plate, and the surface of the sponge plate is coated with a mesh. The flexible connecting plate 13 is located between the first side plate 11 and the first substrate 10, so that there is a spaced space between the first substrate 10 and the first side plate 11.

[0043] The flexible connecting plate 13 at the side edge of the first base body 10 forms a spaced space between the first side plate 11 and the first base body 10. The elastic buffering of the sponge reduces the pressure on the back and waist during wearing. The breathable structure on the surface of the mesh cooperates with the spaced space to promote air circulation and reduce the stuffy feeling during wearing. And during wearing, it can adaptively adjust the wearing tightness of the back and waist according to the change of the abdominal shape, ensuring the stable contact between the monitoring component 30 and the skin, and solving the problems of poor fitting and data interruption caused by the rigid structure of the existing equipment.

[0044] Embodiment 4: Compared with the solution of Embodiment 1, the further solution provided in this embodiment is as follows. Refer to the attached Figure 6 As shown in the figure, a mesh 15 is provided on the upper part of the first base body 10. This mesh 15 is convenient for setting a zipper structure. The two side edges of the mesh 15 can be fitted through the zipper to achieve a tightening effect, and vice versa, the surface area of the upper part of the first base body 10 can be enlarged. The mesh 15 provided on the upper part of the first base body 10 realizes the adjustment of the surface area through the zipper structure. When the zipper fits the two side edges of the mesh 15, the upper part of the first base body 10 can be tightened to make it more fitting to the upper edge of the pregnant woman's back, enhancing the overall wearing stability of the device; on the contrary, opening the zipper can enlarge the surface area of the upper part of the first base body 10 to adapt to different pregnant women's body types or usage requirements. The mesh 15 is made of breathable fabric material.
