Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and more specifically, to a uterine contraction detection patch. Background Art

[0002] Electronic fetal monitoring (EFM) is a technology used to detect fetal heart rate and uterine contractions. It is designed to assess the health of the fetus and monitor the fetal response during obstetric and gynecological medical procedures.

[0003] Electronic fetal heart rate monitoring is commonly performed during the prenatal and labor period and uses electronic devices and sensors to measure the fetal heart rate and maternal uterine contractions. Fetal heart rate monitoring devices usually consist of two main components: fetal heart rate monitoring and maternal uterine contraction monitoring.

[0004] The uterine contraction probe is part of the fetal heart rate monitoring system and is used to monitor the contraction of the pregnant woman's uterus. The main functions of the uterine contraction probe are as follows:

[0005] 1. Monitor the intensity and frequency of uterine contractions: The uterine contraction probe can measure the duration, frequency and intensity of uterine contractions. These data can help doctors and nurses understand the regularity and effectiveness of uterine contractions in order to assess the progress of labor.

[0006] 2. Determine the stage of labor: By detecting the intensity and frequency of uterine contractions, the uterine contraction probe can help doctors and nurses determine the different stages of labor. This helps to determine whether uterine contractions are in line with expected progress so that corresponding labor management can be carried out.

[0007] 3. Evaluate the impact of uterine contractions on the fetus: The uterine contraction probe can record the relationship between uterine contractions and fetal heart rate. When the uterus contracts, pressure is transmitted to the fetus, which may affect the fetal heart rate. By observing the relationship between uterine contractions and fetal heart rate, doctors can evaluate the fetus's tolerance to uterine contractions and find out whether there are problems such as fetal distress.

[0008] 4. Guide labor management and decision-making: Based on the data provided by the uterine contraction probe, doctors and nurses can manage and make decisions on labor according to the conditions of the pregnant woman and fetus. For example, when uterine contractions are too frequent or strong, appropriate measures may be needed to reduce the strength of uterine contractions or ease the frequency of uterine contractions to protect the safety of the fetus and mother.

[0009] In general, the uterine contraction probe is an important component of the fetal heart rate monitor. By monitoring and recording the intensity and frequency of uterine contractions, it provides valuable information about the progress of labor and the condition of the fetus, thereby helping medical staff make appropriate decisions and management to ensure the safety of mother and baby.

[0010] At present, although the existing uterine contraction probe can monitor the uterine contraction data of pregnant women, its defect is that the surface of the existing uterine contraction probe is usually provided with a groove, and the groove contacts the skin of the pregnant woman, which can easily cause bruises or pressure sores on the abdominal skin of the pregnant woman.

[0011] For example, application number 202023286900.7 discloses a more ergonomic uterine contraction pressure probe and detector, including an outer frame and a uterine contraction monitoring piece located inside or outside the outer frame, the outer frame is connected to the edge of the uterine contraction monitoring piece through an annular buffer, and the monitoring surface of the uterine contraction monitoring piece is concave. In the case of most pregnant women who have extended waiting time for delivery, the long-term use of the uterine contraction probe for compression can easily cause pressure sores on the pregnant woman's abdominal skin.

[0012] Therefore, the prior art needs to be improved. Utility Model Content

[0052] See also Figure 1 and Figure 2 The present embodiment provides a uterine contraction detection patch, which includes: a patch substrate 100, a pressure sensor 200, a PCB board 300 and a data transmission unit 400. The patch substrate 100 is used to be attached to a subject, the pressure sensor 200 is arranged on the patch substrate 100, the pressure sensor 200 is used to collect the uterine contraction pressure data of the subject, the PCB board 300 is arranged on the patch substrate 100, and the PCB board 300 is electrically connected to the pressure sensor 200, and the data transmission unit 400 is electrically connected to the PCB board 300.

[0053] In this embodiment, the uterine contraction detection patch uses a patch substrate 100 as a carrier, and the patch substrate 100 can be attached to the abdomen of the subject. It can be understood that the patch substrate 100 can be attached to the abdomen of a pregnant woman to collect uterine contraction pressure data. For example, the patch substrate 100 is inlaid with a pressure sensor 200, a PCB board 300 and a data transmission unit 400. The pressure sensor 200 is used to collect the uterine contraction pressure data of the subject. The pressure sensor 200 sends the collected uterine contraction pressure data to the PCB board 300 to form uterine contraction data. The PCB board 300 can be transmitted to the fetal heart monitor 600 or the mobile device 700 through the data transmission unit 400. The mobile device 700 has different applications, which can monitor the uterine contraction of the pregnant woman. The patch substrate 100 has an adhesive surface, and the adhesive surface has the function of adhesive attachment. The patch substrate 100 is attached to the abdomen of the pregnant woman through the adhesive surface, wherein the adhesive surface is flat and smooth, soft and comfortable, which can reduce damage to the skin of the pregnant woman and avoid bruises or pressure sores on the abdominal skin of the pregnant woman.

[0054] Therefore, in this embodiment, the uterine contraction detection patch can be attached to the abdomen of the subject through the patch substrate 100, and the patch substrate 100 obtains uterine contraction pressure data through the pressure sensor 200 to form uterine contraction data. Among them, the patch substrate 100 is soft and comfortable, and the surface is flat and smooth, which can reduce damage to the skin of pregnant women and avoid bruises or pressure sores on the abdominal skin of pregnant women.

[0055] Specifically, see Figure 1 The patch substrate 100 includes: a latex shell 110, a double-sided mucosal film 120 and a release film 130. A pressure sensor 200, a PCB board 300 and a data transmission unit 400 are arranged in the latex shell 110. The double-sided mucosal film 120 is arranged on the side of the pressure sensor 200 close to the subject, and the release film 130 is arranged on the side of the double-sided mucosal film 120 away from the pressure sensor 200, and the release film 130 and the double-sided mucosal film 120 can be detachably connected.

[0056] In this embodiment, the latex shell 110 is soft and elastic, moderately soft, and not easy to deform. The latex shell 110 is used as a carrier of the pressure sensor 200, the PCB board 300 and the data transmission unit 400, that is, the pressure sensor 200, the PCB board 300 and the data transmission unit 400 can be embedded in the latex shell 110. The double-sided mucosa 120 has an adhesive effect, so that the patch substrate 100 can be adhered to the abdomen of the subject and is not easy to fall off. The release film 130 is used to protect the double-sided mucosa 120. For example, when it is necessary to monitor and record the intensity and frequency of uterine contractions, the release film 130 can be torn off, and then the pressure sensor 200 is bonded to the abdomen of the pregnant woman through the double-sided mucosa 120, and the intensity and frequency of the uterine contractions of the pregnant woman are monitored in real time through the pressure sensor 200.

[0057] For example, see Figure 3 The pressure sensor 200 can adopt an annular pressure sensor 210, which can achieve high-precision measurement, can provide very accurate position information, meet the needs of high-precision monitoring, has a compact structure, is easy to install, and can save space.

[0058] Specifically, see Figure 1 The contraction detection patch may also include: a power switch 111 and an LED light 112, the power switch 111 is arranged on the patch substrate 100, and the power switch 111 is electrically connected to the PCB board 300, and the LED light 112 is arranged on the patch substrate 100, and the LED light 112 is electrically connected to the PCB board 300.

[0059] In this embodiment, the power switch 111 can start or stop the contraction detection patch, the LED light 112 can display the working state of the contraction detection patch, and the LED light 112 can include a power light 113 and a signal light 114. For example, the contraction detection patch can be powered on by pressing the power switch 111. At this time, the power light 113 is on, indicating that the pressure sensor 200 can collect the contraction pressure data of the pregnant woman. When the PCB board 300 is connected to the fetal heart monitor 600 or the mobile device 700 through the data transmission unit 400, the signal light 114 is on; when the PCB board 300 is not connected to the fetal heart monitor 600 or the mobile device 700, the signal light 114 is off; long press the power switch 111 to turn off the power of the contraction detection patch, and the power light 113 and the signal light 114 are both off.

[0060] Specifically, see Figure 2 and Figure 4 The uterine contraction detection patch may further include: a blood oxygen sensor 500 , the blood oxygen sensor 500 is disposed on the patch substrate 100 , and the blood oxygen sensor 500 is electrically connected to the PCB board 300 .

[0061] In this embodiment, the uterine contraction detection patch also has a blood oxygen sensor 500, which is used to collect oxygen concentration and pulse data information in the blood of the subject. During the delivery process of a pregnant woman, it is very important to monitor the pulse and blood oxygen saturation of the pregnant woman. During the delivery process of a pregnant woman, many changes will occur in her body functions. Among them, blood oxygen saturation is a very important parameter. If the blood oxygen level is too low, it may affect the health of the pregnant woman and the fetus. Therefore, monitoring of blood oxygen saturation can ensure that the pregnant woman and the fetus get enough oxygen. If the blood oxygen content is found to be lower than the normal level, the doctor can take some measures to improve the breathing of the pregnant woman. The pulse can reflect the heart condition of the pregnant woman, whether there is fever and bleeding, etc. Therefore, it is necessary to monitor the blood oxygen saturation and pulse rate of the pregnant woman while monitoring the uterine contraction of the pregnant woman.

[0062] The detection of blood oxygen saturation can adopt transmission photoelectric detection technology, reflection photoelectric detection technology or other known detection technology. This part belongs to known technology and has been widely used, so it will not be described in detail.

[0063] For example, the MAX30102 heart rate and blood oxygen sensor 500 can be equipped with a MAX30102 heart rate and blood oxygen chip and a microcontroller with an integrated heart rate and blood oxygen algorithm, which can directly output heart rate and blood oxygen values. The MAX30102 uses PPG photoelectric volumetric pulse wave recording (PhotoPlethysmoGraphy) to measure data. The microcontroller processes and calculates these data to obtain heart rate and blood oxygen values, and then outputs them through the I2C or UART interface, which greatly reduces the difficulty of using the blood oxygen sensor 500 and the resource occupation of the main control. At the same time, the blood oxygen sensor 500 is also equipped with a corresponding host computer, which can directly read data through a computer.

[0064] Therefore, in this embodiment, the uterine contraction data, blood oxygen saturation and pulse data of the pregnant woman can be collected simultaneously through the pressure sensor 200 and the blood oxygen sensor 500, which can improve the collection efficiency, avoid the use of multiple monitoring probes, avoid the entanglement of multiple wires, facilitate the activities of pregnant women, and reduce the risk of restricted activities and falls of pregnant women.

[0065] Specifically, see Figure 2 The blood oxygen sensor 500 includes: an infrared light emitter 510, a red light emitter 520 and a photodetector 530. The infrared light emitter 510 is arranged on the patch substrate 100, the red light emitter 520 is arranged on the patch substrate 100, and the photodetector 530 is arranged on the patch substrate 100. The photodetector 530 is used to receive the light signal emitted by the infrared light emitter 510 and the light signal emitted by the red light emitter 520.

[0066] In this embodiment, the infrared light emitter 510 can emit infrared light, and the red light emitter 520 can emit red light. The infrared light and the red light are absorbed by the photodetector 530 after reflection. Among them, the patch substrate 100 is a flexible material, such as the latex shell 110 and the double-sided mucosa 120 are both flexible materials. The patch substrate 100 can be well attached to the skin along the contour of the skin, and the optical path rarely deforms, so the blood oxygen content in the blood can be better measured.

[0067] For example, the infrared light emitter 510 and the red light emitter 520 can be located on one side of the pressure sensor 200, and the photodetector 530 can be located on the other side of the pressure sensor 200 to monitor the uterine contractions, blood oxygen saturation and pulse data of the pregnant woman in real time, achieve high-precision measurement, and provide very accurate location information to meet the needs of high-precision monitoring. It has a compact structure and is easy to install.

[0068] Specifically, see Figure 3 , Figure 5 and Figure 6 The data transmission unit 400 includes a data line 410, and the data line 410 is used to connect the PCB board 300 and the fetal heart monitor 600 or the mobile device 700.

[0069] In this embodiment, the contraction detection patch can be connected to the fetal heart monitor 600 or the mobile device 700 via the data line 410, and the contraction detection patch can transmit the monitored contraction data, blood oxygen saturation and pulse rate to the fetal heart monitor 600 via the data line 410. For example, the contraction detection patch can be provided with a data interface 411, and the data line 410 can be inserted into the data interface 411 to realize the electrical connection between the PCB board 300 and the fetal heart monitor 600, wherein the fetal heart monitor 600 can be understood as the prior art and will not be described in detail.

[0070] Specifically, see Figure 2 and Figure 5 The data transmission unit 400 may further include a wireless transmission module 420 , and the wireless transmission module 420 is used to connect the PCB board 300 and the fetal heart monitor 600 .

[0071] In this embodiment, the contraction detection patch can be connected to the fetal heart monitor 600 via the wireless transmission module 420. The contraction detection patch can transmit the monitored contraction data, blood oxygen saturation and pulse rate to the fetal heart monitor 600 via the wireless transmission module 420 to monitor the pregnant woman's contraction, blood oxygen saturation and pulse data in real time.

[0072] Optionally, the wireless transmission module 420 includes at least one of the following structures:

[0073] Wifi wireless communication module, Bluetooth wireless communication module, 4G communication module, 5G communication module or Zig-Bee wireless communication module.

[0074] For example, the wireless transmission module 420 may include a Wifi wireless communication module, and the PCB board 300 may wirelessly transmit with the fetal heart monitor 600 via the Wifi wireless communication module to wirelessly transmit the pregnant woman's uterine contraction data, blood oxygen saturation and pulse data to the fetal heart monitor 600.

[0075] For example, the wireless transmission module 420 may include a Bluetooth wireless communication module, and the PCB board 300 may wirelessly transmit with the fetal heart monitor 600 via the Bluetooth wireless communication module to wirelessly transmit the pregnant woman's uterine contraction data, blood oxygen saturation and pulse data to the fetal heart monitor 600.

[0076] For example, the wireless transmission module 420 may include a 4G communication module or a 5G communication module, and the PCB board 300 may wirelessly transmit with the fetal heart monitor 600 through the 4G communication module or the 5G communication module to wirelessly transmit the pregnant woman's uterine contraction data, blood oxygen saturation and pulse data to the fetal heart monitor 600.

[0077] For example, the wireless transmission module 420 may include a Zig-Bee wireless communication module, and the PCB board 300 may wirelessly transmit with the fetal heart monitor 600 through the Zig-Bee wireless communication module to wirelessly transmit the pregnant woman's uterine contraction data, blood oxygen saturation and pulse data to the fetal heart monitor 600.

[0078] For example, the wireless transmission module 420 may include a Wifi wireless communication module, a Bluetooth wireless communication module, a 4G communication module, a 5G communication module and a Zig-Bee wireless communication module. The PCB board 300 may wirelessly transmit with the fetal heart monitor 600 through the Wifi wireless communication module, the Bluetooth wireless communication module, the 4G communication module, the 5G communication module and the Zig-Bee wireless communication module to wirelessly transmit the pregnant woman's uterine contraction data, blood oxygen saturation and pulse data to the fetal heart monitor 600.

[0079] Specifically, see Figure 2 and Figure 6 The wireless transmission module 420 can also be used to connect the PCB board 300 and the mobile device 700.

[0080] The contraction detection patch can be connected to the mobile device 700 via the wireless transmission module 420. The mobile device 700 can execute multiple different applications. The application of the mobile device 700 can monitor the uterine contraction data, blood oxygen saturation and pulse data of the pregnant woman. Therefore, the contraction detection patch can transmit the monitored uterine contraction data, blood oxygen saturation and pulse rate to the mobile device 700 via the wireless transmission module 420 to monitor the uterine contraction, blood oxygen saturation and pulse data of the pregnant woman in real time.

[0081] Optionally, the mobile device 700 may include a smart phone 710 .

[0082] For example, the mobile device 700 may include a smart phone 710, which may have a mobile phone APP. The smart phone 710 can be wirelessly connected to the wireless transmission module 420 via the mobile phone APP to monitor the uterine contractions, blood oxygen saturation and pulse data of the pregnant woman in real time. Among them, the mobile phone APP can be understood as existing technology and will not be repeated.
