Description

Technical Field

[0001] This invention relates to the field of medical assistive devices, and more particularly to a device for fixing breech external cephalic version of a fetus. Background Technology

[0002] Abnormal fetal position is a common obstetric problem in late pregnancy, with breech presentation being one of the most common abnormal positions. Clinical studies show that approximately 3% to 5% of term pregnancies result in breech delivery. Because the fetal head is delivered last, breech delivery carries risks such as neonatal asphyxia, birth injury, and an increased cesarean section rate.

[0003] In existing technologies, commonly used clinical methods for correcting breech presentation mainly include the knee-chest position, knee-chest position exercises, and external cephalic version (ECV). ECV involves the doctor applying moderate pressure to the pregnant woman's abdominal wall and manually rotating the breech fetus to a head-down position. However, after successful breech presentation correction via ECV, the lack of a fetal position fixation device makes it easy for the fetus to revert to a breech or transverse position, leading to inconsistent ECV results.

[0004] It is evident that the existing technology suffers from an unstable fetal position reversal effect after breech external valgus. Summary of the Invention

[0005] The purpose of this invention is to provide a breech external valgus fixation device, which solves the problem of unstable fetal position reversal effect after breech external valgus in the prior art.

[0006] To achieve this objective, the present invention adopts the following technical solution: A device for fixing breech external cephalic version includes an abdominal binder and two fixing pillows. The abdominal binder has a first end and a second end, which are connected by Velcro and form a ring structure. The first end is located inside the annular structure, the second end is located outside the annular structure, and the two fixing pillows are located opposite each other inside the annular structure and on both sides of the abdomen, so that the abdomen forms a longitudinal ellipse; the abdominal binder and the two fixing pillows are used together to fix the breech external valgus position.

[0007] Optionally, the abdominal binder is provided with a zipper for quick assembly and disassembly, and the zipper is disposed adjacent to the first end or the second end.

[0008] Optionally, each of the two fixed pillows is fitted with a first elastic sleeve, and the abdominal binder is fitted with two second elastic sleeves, with the first elastic sleeve and the second elastic sleeve being connected in a one-to-one correspondence.

[0009] Optionally, each of the fixing pillows has a mounting groove, one end of which is open and the other end is closed. A fixing rod is interference-fitted into the mounting groove, and the hardness of the fixing rod is greater than that of the fixing pillow.

[0010] Optionally, both the fixing pillow and the fixing rod are cylindrical, the outer diameter of the fixing pillow is larger than the outer diameter of the fixing rod, one end of the fixing rod is inserted into the mounting groove, and the other end of the fixing rod extends out of the mounting groove.

[0011] Optionally, each of the fixed pillows is provided with a plurality of first pressure relief holes, the first pressure relief holes being connected to both ends of the fixed pillow, and the plurality of first pressure relief holes being arranged around the fixed rod.

[0012] Optionally, each of the fixing rods is provided with a plurality of second pressure relief holes, which are distributed at intervals around the axis of the fixing rod, and the second pressure relief holes are connected to both ends of the fixing rod.

[0013] Optionally, both the first pressure-reducing hole and the second pressure-reducing hole are circular holes, and the inner diameter of the first pressure-reducing hole is larger than the inner diameter of the second pressure-reducing hole.

The second lifting strap and the third lifting strap are arranged diagonally, and the first lifting strap, the second lifting strap and the third lifting strap are all interlaced.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a breech external cephalic version (ECV) fetal position fixation device. By incorporating an abdominal binder and two fixing pillows, it effectively fixes the fetal position after a successful ECV procedure, keeping the fetus in a head-down position and preventing reversion to breech or transverse positions, thereby improving the stability and success rate of the ECV. The abdominal binder uses Velcro fastening for easy donning, doffing, and tightness adjustment, accommodating variations in abdominal circumference among pregnant women. The two fixing pillows are positioned opposite each other on either side of the pregnant woman's abdomen, forming a longitudinal elliptical structure that both limits and supports the fetal position while avoiding excessive pressure on the abdomen, ensuring the comfort and safety of the pregnant woman.

[0020] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] This invention provides a breech external lateral fetal position fixation device, such as... Figures 1 to 5 As shown, it includes an abdominal binder 10 and two fixing pillows 20. The abdominal binder 10 has a first end 11 and a second end 12. The first end 11 and the second end 12 are connected by Velcro and enclosed to form a ring structure. The first end 11 is located inside the annular structure, and the second end 12 is located outside the annular structure. Two fixing pillows 20 are positioned opposite each other inside the annular structure and on either side of the abdomen, forming a longitudinal ellipse shape. The abdominal binder 10 and the two fixing pillows 20 are used together to fix the breech-facing external cephalic version of the fetus. In this embodiment, the fixing pillow 20 can be a cylindrical structure made of rolled-up towel, or it can be made of sponge.

[0024] It should be noted that the breech external cephalic version (ECV) fetal position fixation device provided by this invention, by setting up an abdominal binder 10 and two fixing pillows 20, can effectively fix the fetal position after a successful ECV procedure, keeping the fetus in a head-down position and preventing it from turning back to a breech or transverse position, thereby improving the stability and success rate of the ECV. Because the abdominal binder 10 uses Velcro fasteners, it is easy to put on and take off and adjust its tightness, adapting to the differences in abdominal circumference among pregnant women; the two fixing pillows 20 are arranged opposite each other on both sides of the pregnant woman's abdomen, forming a longitudinal elliptical structure, which can both limit and support the fetal position while avoiding excessive pressure on the abdomen, ensuring the comfort and safety of the pregnant woman. Therefore, this invention not only solves the problem of unstable fetal position after breech ECV in the prior art, but also has the advantages of simple structure, convenient operation, strong applicability, and high clinical application value.

[0025] like Figures 1 to 5 As shown, the abdominal binder 10 is provided with a zipper 30 for quick assembly and disassembly of the abdominal binder 10, and the zipper 30 is arranged adjacent to the first end 11 or the second end 12.

[0026] In practice, by setting a zipper 30 on the abdominal binder 10 and placing the zipper 30 near the first end 11 or the second end 12, the abdominal binder 10 can be quickly attached and detached, further improving the ease of operation of the device and solving the problems of cumbersome wearing and inconvenient adjustment of existing fixation devices. At the same time, compared with the method of relying solely on Velcro connection, the zipper 30 can enhance the overall stability of the abdominal binder 10, preventing it from loosening due to force during the pregnant woman's activities or use, thereby ensuring the reliability and continuity of fetal position fixation.

[0027] like Figure 2 and Figure 3 As shown, each of the two fixed pillows 20 is fitted with a first elastic sleeve 40, and the abdominal binder 10 is fitted with two second elastic sleeves 50. The first elastic sleeve 40 and the second elastic sleeve 50 are connected in a one-to-one correspondence. In this embodiment, the arrangement of the first elastic sleeve 40 and the second elastic sleeve 50 facilitates the assembly and use of the abdominal binder 10 and the fixed pillows 20. Furthermore, by moving the position of the second elastic sleeve 50, the fixed pillows 20 can be installed at different positions on the abdominal binder 10, solving the problem of easy displacement of the fixed pillows 20. Since the first elastic sleeve is fitted onto the fixed pillows 20, the position of the fixed pillows 20 can be moved according to actual needs, allowing for flexible adjustment of the fixed pillows 20's position.

[0028] In practical implementation, by setting a first elastic sleeve 40 on each of the two fixed pillows 20 and a corresponding second elastic sleeve 50 on the abdominal binder 10, and connecting the first elastic sleeve 40 and the second elastic sleeve 50 in a one-to-one correspondence, the fixed pillows 20 can be stably fixed inside the abdominal binder 10, preventing displacement or slippage during use. Furthermore, the elastic sleeves' stretching properties reduce local pressure on the pregnant woman's abdomen while ensuring a secure fit, thus improving comfort and safety during use. This structure is easy to assemble, disassemble, and clean, enhancing the device's practicality and reusability.

[0029] like Figures 2 to 5 As shown, each fixed pillow 20 has an installation groove 21. One end of the installation groove 21 is open and the other end is closed. A fixing rod 60 is interference-fitted in the installation groove 21. The hardness of the fixing rod 60 is greater than that of the fixed pillow 20.

[0030] In practical implementation, an installation groove 21, open at one end and closed at the other, is made on the fixing pillow 20. A fixing rod 60 is then installed within the groove 21 with an interference fit. Utilizing the fact that the fixing rod 60 is harder than the fixing pillow 20, the overall support and shaping effect of the fixing pillow 20 are enhanced, preventing it from collapsing or deforming under pressure during use. This ensures the stability and durability of fetal position fixation, solving the problem of the fixing pillow 20 being too soft and lacking sufficient support. Simultaneously, this structure allows the fixing pillow 20 to maintain a good fit and limiting effect, improving not only the reliability of the device but also the user experience for pregnant women.

[0031] like Figures 2 to 5 As shown, both the fixing pillow 20 and the fixing rod 60 are cylindrical. The outer diameter of the fixing pillow 20 is larger than the outer diameter of the fixing rod 60. One end of the fixing rod 60 is inserted into the mounting groove 21, and the other end of the fixing rod 60 extends out of the mounting groove 21.

[0032] In practical implementation, the cylindrical design of both the fixing pillow 20 and the fixing rod 60 simplifies the manufacturing process and facilitates assembly. The outer diameter of the fixing pillow 20 is larger than that of the fixing rod 60, creating a reliable interference fit between them and ensuring the stability of the fixing rod 60 within the pillow body. Furthermore, since one end of the fixing rod 60 is inserted into the mounting groove 21 and the other end extends out of it, this not only enhances the overall support strength and deformation resistance of the fixing pillow 20 but also provides additional support and restraint in the extended portion, further improving the stability and reliability of tire position fixing. Simultaneously, this structure avoids the risk of loosening or collapsing of the fixing pillow 20 during long-term use, improving the durability and safety of the device.

[0033] like Figure 4 and Figure 5 As shown, each fixed pillow 20 has several first pressure-reducing holes 22, which are connected to both ends of the fixed pillow 20. These first pressure-reducing holes 22 are arranged around the fixed rod 60. Each fixed rod 60 has several second pressure-reducing holes 61, which are spaced around the axis of the fixed rod 60 and are connected to both ends of the fixed rod 60. Both the first pressure-reducing holes 22 and the second pressure-reducing holes 61 are circular holes, with the inner diameter of the first pressure-reducing hole 22 being larger than the inner diameter of the second pressure-reducing hole 61.

[0034] In practice, by creating several first pressure-reducing holes 22 on the fixing pillow 20 that penetrate both ends, and distributing these first pressure-reducing holes 22 around the fixing rod 60, the reaction force of the fixing pillow 20 as a whole during the pressure process can be effectively reduced, increasing breathability and flexible fit, thereby improving the comfort of pregnant women when wearing it and solving the problem of decreased comfort caused by the fixing pillow 20 being too heavy or not breathable. At the same time, several second pressure-reducing holes 61 that penetrate both ends are distributed around the fixing rod 60 along the axial direction, which not only reduces the weight of the fixing rod 60, but also further buffers external forces while maintaining sufficient support strength, avoiding discomfort to pregnant women caused by the excessive rigidity of the fixing rod 60. Since the inner diameter of the first pressure-reducing hole 22 is larger than the inner diameter of the second pressure-reducing hole 61, a graded pressure-reducing structure with a soft outer layer and a rigid inner layer is formed, which ensures the stability of fetal position fixation while taking into account the safety and comfort of the pregnant woman's abdomen, solving the problem of weakened structural strength or insufficient comfort caused by improperly sized pressure-reducing holes, and balancing the needs of weight reduction and support.

[0035] like Figure 1 and Figure 2 As shown, the second end 12 is provided with a first lifting strap 70, and the second elastic sleeve 50 is provided with a second lifting strap 80 and a third lifting strap 90. The second lifting strap 80 and the third lifting strap 90 are arranged diagonally, and the first lifting strap 70, the second lifting strap 80, and the third lifting strap 90 are all interlaced. In this embodiment, the first lifting strap 70 is sewn onto the second end 12 with needle and thread, and the second lifting strap 80 and the third lifting strap 90 can be sewn onto the second elastic sleeve 50 with needle and thread. The first lifting strap 70 facilitates the quick separation of the second end 12 from the first end 11; the second lifting strap 80 and the third lifting strap 90 facilitate the movement of the second elastic sleeve 50 on the abdominal binder 10, and facilitate the adjustment of the position of the fixing pillow 20.

[0036] In specific implementation, a first lifting strap 70 is provided on the second end 12 of the abdominal binder 10, and a second lifting strap 80 and a third lifting strap 90 are provided on the second elastic sleeve 50, which are diagonally distributed and arranged in an alternating manner. The first lifting strap 70, the second lifting strap 80, and the third lifting strap 90 can form a multi-directional pulling and limiting effect when the abdominal binder 10 and the fixing pillow 20 are in use. On the one hand, this helps to further enhance the stability between the fixing pillow 20 and the abdominal binder 10, preventing the device from loosening or shifting due to changes in the pregnant woman's position; on the other hand, the alternating lifting structure can distribute the force, making the restraint on the abdomen more even, ensuring both the fetal position fixation effect and improving the comfort of the pregnant woman. Furthermore, the lifting straps are fixed by sewing, resulting in a sturdy structure that is simple to process and easy to promote and apply on a large scale. Therefore, this embodiment solves the problem that the abdominal binder 10 is prone to shifting and its fixation effect decreases during activity, ensuring reliable fixation of the fixation device under dynamic conditions.

[0037] It is worth mentioning that a pressure detection module is also included. This module comprises a flexible pressure sensor mounted on at least one fixed pillow 20, a data processing unit electrically connected to the flexible pressure sensor, and a display unit communicatively connected to the data processing unit. The pressure detection module is used to detect and display the pressure information applied to the abdomen by the fixed pillow 20 in real time. In this embodiment, the data processing unit and the display unit are well-known technologies in the art and will not be described in detail here. The first pressure-reducing hole 22 can also serve as a wire passage hole, facilitating the passage of the wire connected to the flexible pressure sensor.

[0038] In practical implementation, by setting a flexible pressure sensor on the fixation pillow 20, and combining it with a data processing unit and a display unit to form a pressure detection module, real-time monitoring and display of the pressure applied by the fixation pillow 20 to the pregnant woman's abdomen can be achieved. This structure can not only effectively avoid discomfort to the pregnant woman or the risk of fetal compression due to excessive pressure, but also provide doctors or pregnant women with intuitive pressure data, facilitating timely adjustment of the tightness of the abdominal binder 10 based on the monitoring results, thereby improving the safety and scientific nature of use while ensuring the fetal position fixation effect. In addition, the flexible sensor has a simple structure and high sensitivity, making it suitable for integration with the device, thus enhancing the overall intelligence level and clinical application value of the invention.

[0039] It is also worth mentioning that the breech external lateral fetal position fixing device provided in this embodiment of the invention uses the following method for pressure adjustment, including: Step S1: The breech external cephalic version is fixed by the abdominal binder 10 and the fixation pillow 20, and a target pressure range is set; wherein, the target pressure range is determined based on the comfort state of the pregnant woman's abdomen and the stability of the fetal position after the breech external cephalic version is successful.

[0040] Specifically, after successfully turning the fetus to a head-down position via external cephalic version, the clinician applies this fixation device to the pregnant woman. The abdominal binder 10 is adjusted so that the two fixation pillows 20 are securely placed on either side of the pregnant woman's abdomen, forming an ideal longitudinal oval fixation shape. Subsequently, the doctor, combining ultrasound monitoring of fetal position and the pregnant woman's subjective comfort feedback, performs fine manual adjustments to the tightness of the fixation device. When it is confirmed that the fetal heart rate is normal, the fetal position is stable, and the pregnant woman feels comfortable and without pressure, the system's main control module records the average pressure values ​​on the left and right sides measured by the flexible pressure sensor array at this time. Based on this, it automatically generates a target pressure range (e.g., target value ±10%). This range is stored in the main control module's non-volatile memory as a reference for subsequent automatic adjustments.

[0041] Step S2: The pressure data on both sides of the abdomen is collected in real time at a preset frequency by a flexible pressure sensor array embedded in each fixed pillow 20.

[0042] Specifically, a flexible pressure sensor array embedded in the inner surface of the two fixed pillows 20 continuously collects pressure data from both sides of the abdomen at a preset sampling frequency (e.g., 1 time / second). This data is transmitted to the main control module in real time.

[0043] Step S3: Process the received pressure data, calculate the left average pressure value and the right average pressure value, and compare the left average pressure value and the right average pressure value with the target pressure range to determine whether the pressure state is in a balanced state or an unbalanced state.

[0044] Specifically, data processing is performed by introducing existing filtering algorithms into the microprocessor of the main control module. These algorithms can be moving average filtering, Kalman filtering, or median filtering, etc., to eliminate signal interference caused by brief fetal movements or the pregnant woman's momentary physical activity, and to calculate the average pressure values ​​on the left and right sides for the current cycle. The main control module compares the average pressure values ​​on both sides with preset target pressure ranges to determine the current pressure status. If both the left and right average pressure values ​​are within their respective target pressure ranges, and the pressure difference is less than a preset balance threshold (e.g., 5%), the system determines the state is stable and does not trigger adjustment. Unilateral pressure imbalance manifests as pressure values ​​on one side exceeding the upper limit of the target pressure range, while the pressure value on the other side is normal or low. For example, when a pregnant woman lies on her left side, the average pressure value on the left side may increase significantly, while the average pressure value on the right side decreases accordingly. This indicates that the fetus tends to move towards the side with lower pressure (the right side). Overall pressure change manifests as both average pressure values ​​deviating from the target pressure range simultaneously. If the average pressure value on both sides remains below the lower limit of the target pressure range, it indicates that the abdominal binder is generally loose; if the average pressure value on both sides remains above the upper limit of the target pressure range, it indicates that the abdomen may be subjected to excessive pressure due to posture or uterine contractions.

[0045] Step S4: When the pressure state is determined to be unbalanced, corresponding pressure adjustment is performed. If it is a unilateral pressure imbalance, the length of the fixing rod 60 is adjusted to correct the pressure difference between the left and right sides. If it is an overall pressure change, the tightness of the abdominal binder 10 is adjusted to bring the average pressure value on both sides back to the target pressure range. In this embodiment, the fixing rod 60 consists of inner and outer sleeves. The fixing rod 60 can be extended and retracted using a micro stepper motor or manually, allowing for fine-tuning of its length (e.g., extension range ±2cm). The micro stepper motor driving the fixing rod 60 to extend and retract is existing technology and will not be described further here.

[0046] Specifically, for unilateral pressure imbalance, the system primarily controls the retractable fixing rod 60. For example, in the case of excessive pressure on the left side, the main control module will control the left retractable fixing rod 60 to move, slightly shortening it (e.g., contracting by 1 mm); simultaneously, it instructs the right fixing rod 60 to slightly extend. This extension and retraction action is equivalent to applying a gentle push from left to right, aiming to shift the fetal center of gravity to the opposite side to correct the left-right pressure difference, counteract fetal rotation, and restore pressure balance. For changes in overall pressure, the system primarily controls the tightness adjustment of the abdominal binder 10. If the overall pressure is too low (abdominal binder 10 is loose), the abdominal binder 10 is slightly tightened until the average pressure value on both sides returns to the target pressure range. If the overall pressure is too high (excessive compression), the abdominal binder 10 is slightly loosened to reduce pressure, ensuring maternal comfort and fetal safety.

[0047] It should be noted that this method, through real-time monitoring and feedback adjustment, can intelligently maintain the fixation pressure within the optimal range based on dynamic factors such as changes in body position and fetal activity. This greatly improves the stability and success rate of fetal position fixation, solving the problem of existing devices having a fixed fixation force that cannot adapt to the daily activities of pregnant women. By setting a target pressure range and feedback adjustment, the risk of maternal discomfort, skin injury, or impaired placental blood circulation caused by excessive tightness is effectively avoided. At the same time, by relieving excessive tightness and adjusting in time when it is too loose, the safety and comfort of the entire wearing process are ensured. For unilateral pressure imbalance (i.e., signs of fetal repositioning), this method can actively and promptly adjust the length of the fixation rod (60mm) to apply a gentle corrective force to the fetus, actively pushing the fetal position back to a stable state, solving the problem of easy recurrence of abnormal fetal position after external cephalic version.

[0048] Working Principle: This invention provides a breech external cephalic version (ECV) fetal position fixation device. By incorporating an abdominal binder 10 and two fixing pillows 20, it effectively fixes the fetal position after a successful ECV procedure, maintaining the fetus in a head-down position and preventing reversion to breech or transverse positions, thereby improving the stability and success rate of the ECV. The abdominal binder 10 uses Velcro fastening for easy donning, doffing, and tightness adjustment, accommodating variations in abdominal circumference among pregnant women. The two fixing pillows 20 are positioned opposite each other on either side of the pregnant woman's abdomen, forming a longitudinal elliptical structure that both limits and supports the fetal position while avoiding excessive pressure on the abdomen, ensuring the comfort and safety of the pregnant woman. Therefore, this invention not only solves the problem of unstable ECV results in existing technologies but also boasts advantages such as simple structure, convenient operation, strong applicability, and high clinical application value.
