Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and specifically relates to a pregnancy and childbirth assistance device and its intelligent evaluation system. Background Art

[0002] Childbirth, as an important process of human reproduction, is a process in which the mother undergoes a series of complex physiological changes and finally gives birth to the fetus. This process not only concerns the life safety of the mother and the baby, but also directly affects the mother's postpartum recovery and the health status of the newborn. During childbirth, the mother will experience multiple stages such as uterine contractions, cervical dilation, fetal descent and delivery, and these stages are accompanied by intense pain and pressure, which are a great test for the mother's physical and mental health.

[0003] The existing risk assessment for pregnant and lying-in women mainly relies on doctors' clinical experience and regular examinations. Although this method can identify some obvious risk factors to a certain extent, there are some inherent limitations in this way. The physical condition of pregnant and lying-in women is constantly changing during pregnancy, and the existing assessment system is often based on general models and standardized parameters, making it difficult to fully capture the risk changes brought about by individual differences. Inaccurate risk assessment may increase the risk of complications during childbirth, such as third-degree lacerations during normal delivery, which not only bring additional physical trauma to the mother, but may also affect her subsequent reproductive health and quality of life.

[0004] In view of the defects of the existing technology, there is an urgent need for a childbirth assistance device and its intelligent evaluation system that can real-time monitor the changes in physiological indicators of pregnant and lying-in women during childbirth and realize dynamic assessment of risks. Summary of the Invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a pregnancy and childbirth assistance device and its intelligent evaluation system, which can improve childbirth safety and reduce the risk of complications.

[0006] In order to achieve the above purpose, the technical solution of the present invention is as follows:

[0007] A pregnancy and childbirth intelligent evaluation system includes a data acquisition module, a data processing module, an evaluation module and an output module;

[0008] The data acquisition module is used to obtain dynamic data and static data related to the delivery of the parturient;

[0009] The data processing module is used to preprocess the dynamic data and static data;

[0010] The evaluation module is used to build a deep neural network model based on the attention mechanism as the risk assessment model, and use the attention mechanism to dynamically adjust the model's attention to different features of dynamic data and static data; and input the processed dynamic data and static data into the trained risk assessment model to obtain a prediction result.

[0011] The output module is used to output a personalized childbirth risk assessment report according to the prediction result of the risk assessment model.

[0012] The following beneficial effects are achieved by adopting the above solution:

[0013] In this solution, the data acquisition module obtains comprehensive data related to the delivery of pregnant women, including dynamic data such as real-time physiological index changes, and static data such as the basic information and medical history of pregnant women. The data processing module preprocesses these data to ensure the accuracy and availability of the data. The evaluation module uses a deep neural network model based on the attention mechanism, which can accurately identify and analyze various features related to childbirth risks, organically integrate the features of different data sources related to the delivery of pregnant women, and utilize the complementary and synergistic effects between multi-modal data to improve the comprehensive judgment ability of the system. By dynamically adjusting the attention to different features, it can more accurately predict the risks that occur during childbirth, take preventive measures in advance, and effectively improve the safety of childbirth.

[0014] Furthermore, the dynamic data includes but is not limited to the frequency and intensity of uterine contractions, the degree of cervical dilation, the speed of cervical dilation, the degree of pelvic opening, the pain condition of the pregnant woman, the physical strength of the pregnant woman, the mental state of the pregnant woman, and the fetal heart rate; the static data includes but is not limited to age, weight, height, pelvic size, previous delivery history, surgical history, complication history, and fetal weight.

[0015] Beneficial effects: The real-time collection and analysis of dynamic data, such as the frequency and intensity of uterine contractions, the degree and speed of cervical dilation, and the degree of pelvic opening, provide the system with the immediate physiological state of the pregnant woman during childbirth, which helps to detect abnormal situations in a timely manner.

[0016] The collection of static data, such as age, weight, height, pelvic size, etc., provides the system with the basic physiological characteristics and delivery history of the pregnant woman, which helps to more accurately assess the childbirth risk.

[0017] By organically combining these two types of data, the system can more accurately assess the childbirth risk and provide timely and effective decision-making support for medical staff.

[0018] A pregnancy and childbirth assistance device, comprising a main body; a back support carrier, a hip support carrier, armrests and a function rack are arranged on the main body; the back support carrier and the hip support carrier are both located at the top of the main body, a sound collection unit for obtaining the pain sounds of the parturient is arranged on the back support carrier, leg brackets are respectively arranged on both sides of the hip support carrier, and a first pressure sensor for collecting the leg pressure of the parturient is arranged on the leg brackets; the armrests are located on both sides of the main body, a second pressure sensor for collecting the hand pressure of the parturient and a humidity sensor for collecting the hand sweat condition are arranged on the armrests; the function rack is located on one side of the main body, and a fetal heart rate monitor for monitoring the fetal heart rate in the parturient's body, a Doppler ultrasound detector for detecting the degree and speed of cervical dilation and the degree of pelvic opening, and a uterine contraction monitor for detecting the frequency and intensity of uterine contractions are placed on the function rack;

[0019] It further comprises a control unit; the control unit is used to comprehensively judge the pain condition of the parturient based on the information of the sound collection unit, the information of the humidity sensor, and the information of the first pressure sensor and the second pressure sensor, and comprehensively judge the physical strength condition of the parturient based on the information of the first sensor and the second pressure sensor.

[0020] Adopting the above scheme has the following beneficial effects: In this scheme, the pain sounds of the parturient are obtained through the sound collection unit, combined with the hand sweat condition detected by the humidity sensor, and the leg and hand pressure information collected by the first pressure sensor and the second pressure sensor respectively, the control unit can comprehensively evaluate the pain condition of the parturient based on these factors. This multi-parameter comprehensive evaluation method is more accurate than a single index and can more comprehensively reflect the actual pain condition of the parturient. Through the pressure sensor information of the legs and hands, the control unit can also judge the physical strength condition of the parturient. This helps medical staff understand the physical strength consumption of the parturient during childbirth, so as to take timely measures to support the parturient's physical strength.

[0021] Based on the accurate evaluation of the parturient's pain and physical strength, medical staff can formulate and adjust childbirth strategies more scientifically. For example, when the parturient's pain intensifies or physical strength fails, medical staff can timely adjust the childbirth method (such as changing from natural childbirth to cesarean section), give drug analgesia or provide physical strength support (such as fluid infusion, massage, etc.), so as to optimize the childbirth process and improve the safety and comfort of childbirth.

[0022] A variety of childbirth assistance tools such as a fetal heart rate monitor, a Doppler ultrasound detector and a uterine contraction monitor are integrated on the function rack. These tools can real-time monitor key indicators such as fetal heart rate, degree and speed of cervical dilation, degree of pelvic opening, and frequency and intensity of uterine contractions, providing comprehensive childbirth monitoring data for medical staff, and helping to timely discover and handle abnormal situations during childbirth.

[0023] By comprehensively evaluating the status of the parturient and real-time monitoring of the physiological indicators of the fetus and the parturient, medical staff can more accurately judge the progress of childbirth and potential risks, and thus take more effective intervention measures.

[0024] Furthermore, a massage chamber is provided on the back support carrier, and a massage component is provided in the massage chamber. The control unit is further configured to control the operation of the massage component based on the pain condition of the parturient.

[0025] Beneficial effects: The massage component can perform precise massage on the back of the parturient, which helps to relieve back pain and muscle tension during childbirth. By adjusting the massage intensity and frequency in real-time according to the feedback of the parturient's pain condition by the control unit, the maximization of the massage effect can be ensured, providing immediate pain relief for the parturient.

[0026] Furthermore, the massage component includes a spherical segment carrier and an annular carrier; the spherical segment carrier is located above the annular carrier, and a sliding mechanism is provided between the spherical segment carrier and the annular carrier for realizing the relative sliding of the spherical segment carrier in the direction away from the annular carrier; a plurality of rotary support components are circumferentially arranged between the annular carrier and the bottom of the massage chamber for driving the annular carrier to perform circumferential movement; a lifting component is further provided at the center of the bottom of the massage chamber for driving the spherical segment carrier to perform lifting movement.

[0027] Beneficial effects: By driving the spherical segment carrier to perform lifting movement through the lifting component, and at the same time driving the annular carrier to perform circumferential movement through the rotary support component, since a sliding mechanism is provided between the spherical segment carrier and the annular carrier, the annular carrier will drive the spherical segment carrier to perform circumferential movement while moving, and further, the spherical segment carrier will perform annular lifting movement, thereby performing annular massage on the back of the parturient.

[0028] Through the synergistic effect of the lifting component and the rotary support component, the spherical segment carrier can perform lifting and circumferential movements simultaneously. This multi-dimensional dynamic massage mode not only increases the diversity of massage, but also can more effectively stimulate the back muscles and acupoints, promote blood circulation, and relieve muscle tension and fatigue.

[0029] The introduction of the lifting component enables the massage intensity and depth of the spherical segment carrier to be adjusted according to the needs of the parturient. For parturients with different constitutions and pain degrees, a personalized massage experience can be achieved by adjusting the lifting height, ensuring that the massage is both comfortable and effective.

[0030] The combined design of the spherical segment carrier and the annular carrier, and the sliding mechanism between them ensure that the massage can fully cover the back area of the parturient. The circumferential movement of the annular carrier drives the spherical segment carrier to move together, realizing uniform massage of each part of the back and avoiding massage blind spots.

[0031] Furthermore, a hot compress component is also provided on the spherical segment carrier, and the hot compress component is used to perform hot compress treatment on the back of the parturient.

[0032] Beneficial effects: While massaging, the hot compress component can provide warmth to the back of the parturient, further relaxing the tense muscles and relieving the pain and discomfort brought by childbirth. The combination of hot compress and massage can produce a synergistic effect, significantly enhancing the soothing effect. The hot compress can dilate blood vessels, promote blood circulation, and thus accelerate metabolism and the excretion of waste. During childbirth, the back muscles often become tense and stiff due to maintaining the same posture for a long time, and the hot compress treatment helps to improve this condition and promote the relaxation and recovery of the back muscles.

[0033] Furthermore, the hot compress component includes a heat generation layer opened at the top of the spherical segment carrier; a number of compression pipes are arranged in the heat generation layer, and a heat conduction plate is arranged at the top of the heat generation layer; a number of sealing grooves are circumferentially arranged on the inner periphery of the annular carrier, and pistons are slidably fitted in the sealing grooves; the sliding mechanism includes a number of telescopic shafts, the telescopic shafts correspond to the sealing grooves one by one, the bottoms of the telescopic shafts are all embedded in the sealing grooves and fixedly connected with the pistons, the telescopic shafts are all slidably fitted with the annular carrier, the tops of the telescopic shafts are fixedly connected with the spherical segment carrier, and connecting channels are arranged in the telescopic shafts, and the connecting channels are respectively communicated with the compression pipes; the compression pipes are of Tesla valve pipe structures, and the flow rate of air decreases after entering the Tesla valve pipes.

[0034] Beneficial effects: Through the relative movement between the spherical segment carrier and the annular carrier, the sliding of the pistons in the sealing grooves effectively compresses the air in the connecting pipes and the compression pipes. This mechanical compression process increases the internal energy of the air, raises its temperature, and thus generates heat. The heat conduction plate is responsible for efficiently transferring this heat to the back of the parturient to achieve the effect of hot compress.

[0035] This hot compress component adopts an innovative heat energy generation method, that is, using the physical compression principle rather than traditional electric heating elements to generate heat. This method not only reduces the dependence on external power supplies but also improves the efficiency and safety of heat energy generation.

[0036] The design principle of the Tesla valve pipe structure lies in its unique internal geometry, which can guide the air to flow in a specific way in the pipe. When the air enters the Tesla valve pipe, due to its special channel design, the flow rate will be significantly reduced. This deceleration effect actually helps to increase the residence time and pressure accumulation of the air in the pipe, thus enhancing the air compression effect.

[0037] Since the Tesla valve pipe can compress the air more effectively, it means that under the same input power, the system can do more work on the air (making the collision of air molecules more intense under the same compression ratio), and the better the temperature increase effect.

[0038] Furthermore, the rotary support assembly includes a connecting rod; rotary supports are arranged at both ends of the connecting rod; the rotary support includes a rectangular frame; first rotating shafts are respectively arranged on both sides of the rectangular frame, and a second rotating shaft is arranged inside the rectangular frame. The directions of the first rotating shafts and the second rotating shaft are perpendicular. The first rotating shafts are rotatably connected to bases, and the bases are respectively located at the bottom of the annular carrier and the bottom of the massage chamber; driving members are arranged on one side of any two bases in any vertical direction, and the driving members are used to drive the first rotating shafts to rotate.

[0039] Beneficial effects: By driving the two first rotating shafts in the vertical direction respectively by the driving members, the connecting rod performs circumferential movement with the rectangular frame as the rotation base point. This design enables the annular carrier to perform circumferential movement smoothly and continuously, providing a more comfortable and comprehensive massage experience for the parturient.

[0040] The rotary support adopts a rectangular frame design and realizes multi-directional rotation through the first rotating shaft and the second rotating shaft. This structure not only improves the stability of the rotary support assembly, but also makes the annular carrier not prone to shaking or tilting during rotation, thus ensuring the accuracy and comfort of the massage.

[0041] Furthermore, the lifting assembly includes a hydraulic cylinder; both ends of the hydraulic cylinder are rotatably connected to the bottom of the massage chamber and the bottom of the spherical segment carrier respectively.

[0042] Beneficial effects: The hydraulic cylinder is known for its stable and controllable driving force, and can ensure that the spherical segment carrier maintains a stable movement trajectory during the lifting process. This stability is crucial for the massage process and can avoid discomfort to the parturient caused by sudden or violent lifting actions.

[0043] Furthermore, a diversion groove is also arranged on the hip support carrier, and the diversion groove is communicated with a body fluid detection assembly; the body fluid detection assembly includes a drawer; a detection groove is arranged inside the drawer, a blood detection unit and a body fluid detection unit are arranged in the detection groove, the body fluid detection unit is used to collect the body fluid content in the detection groove, and the blood detection unit is used to detect the blood content in the body fluid; the control unit is also used to judge the amniotic fluid content based on the body fluid content and the blood content; an early warning module is also included, and the early warning module is used to judge whether the parturient needs a cesarean section based on the amniotic fluid content and the blood content, and give an early warning of the body fluid loss situation of the parturient.

[0044] Beneficial effects: The design of the diversion groove can efficiently guide the body fluids (such as amniotic fluid, blood, etc.) generated by the parturient during childbirth to the body fluid detection assembly.

[0045] The body fluid detection unit can accurately collect the body fluid sample in the detection groove, and quantitatively analyze the blood content in the body fluid through the blood detection unit. The control unit then accurately judges the actual amniotic fluid content through an algorithm model based on the comprehensive data of the body fluid content and the blood content, providing accurate monitoring results.

[0046] Through the provided diversion channels and body fluid detection components, the system can collect and analyze the body fluid information of parturients in real time, including the content of body fluids and blood. This function is crucial for monitoring possible abnormalities during childbirth, such as excessive or insufficient amniotic fluid, bleeding, etc., helping doctors make timely judgments and take corresponding measures, thus greatly improving the safety of the childbirth process.

[0047] The warning module can intelligently judge whether a cesarean section is needed for the parturient based on the detection results of the amniotic fluid content and blood content, and give warnings about the body fluid loss of the parturient. Such an intelligent warning system not only improves the decision-making efficiency of doctors but also can provide timely treatment for the parturient in case of emergencies, reducing the risks during the childbirth process.

For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific situations.

[0061] The following is a further detailed description through specific implementation manners:

[0062] Embodiment 1 is basically as shown in the attached Figure 1 drawing:

[0063] An intelligent pregnancy and childbirth assessment system mainly includes a data acquisition module, a data processing module, an assessment module, and an output module.

[0064] The data acquisition module is responsible for comprehensively collecting various types of data related to maternal childbirth, which are divided into two categories: dynamic data and static data. Specifically, dynamic data: data monitored in real-time or periodically, used to reflect the immediate situation during childbirth. In this embodiment, the dynamic data includes, but is not limited to, the frequency and intensity of uterine contractions, the degree of cervical dilation, the speed of cervical dilation, the degree of pelvic opening, the pain condition of the parturient, the physical strength of the parturient, the mental state of the parturient, and the fetal heart rate.

[0065] Static data: basic information of the parturient and the fetus, used to establish a baseline assessment. In this embodiment, the static data includes, but is not limited to, age, weight, height, pelvic size, previous childbirth history, surgical history, complication history, and fetal weight.

[0066] The data processing module is used to preprocess the dynamic data and static data. The collected dynamic data and static data are cleaned, integrated, and standardized to ensure the accuracy and consistency of the data.

[0067] The evaluation module is used to construct a deep neural network model based on the attention mechanism as a risk assessment model, and use the attention mechanism to dynamically adjust the model's attention to different features of the dynamic data and static data; and input the processed dynamic data and static data into the trained risk assessment model to obtain a prediction result. Preferably, in the risk assessment of pregnancy and childbirth, the influence degrees of different data features on childbirth risk are different. For example, the abnormal change of fetal heart rate has a more direct and crucial impact on childbirth risk than the height of the parturient. Through the attention mechanism, the model can dynamically adjust the attention to various features such as the frequency and intensity of uterine contractions, the degree of cervical dilation, and the fetal heart rate, so as to more accurately capture the important information related to childbirth risk in the data.

[0068] Preferably, the construction steps of the evaluation module include: according to the characteristics and requirements of pregnancy and childbirth risk assessment, select a suitable deep neural network architecture, such as a multi-layer perceptron (MLP), a convolutional neural network (CNN), or a recurrent neural network (RNN), etc. In this system, considering the time series characteristics of childbirth data and the different attention degrees to different features, it is more appropriate to use a recurrent neural network combined with the attention mechanism (such as the LSTM-Attention model). LSTM (Long Short-Term Memory network) can effectively process time series data and capture the long-term dependence relationship in the data, while the attention mechanism can further enhance the model's attention to key features.

[0069] Determine the appropriate number of network layers and the number of neurons in each layer through experiments and experience. Generally speaking, the number of network layers should not be too many, otherwise problems such as gradient disappearance or gradient explosion are likely to occur, affecting the training and convergence of the model.

[0070] Integrate the attention mechanism into the selected neural network architecture. Add an attention layer after the LSTM layer of the model. The attention layer determines the degree of attention of the model to different features by calculating the weights of each input feature. These weights are dynamically adjusted according to different input data, so that when the model processes different childbirth data, it can automatically focus on the key features related to childbirth risks. For example, when calculating the attention weights, methods such as dot product operation or multi-layer perceptron can be used to calculate the similarity between the input features and a learnable query vector, and then obtain the attention weights of each feature.

[0071] Use the training set data (historical dynamic data and static data in this embodiment) to train the constructed deep neural network model based on the attention mechanism. During the training process, by continuously adjusting the parameters of the model (such as the connection weights between neurons), the difference between the prediction result of the model and the actual childbirth risk label is minimized. The training method adopted in this embodiment is the backpropagation algorithm, which calculates the gradient of the cross-entropy loss function with respect to the model parameters, and then uses optimization algorithms such as gradient descent to update the parameters. At the same time, some regularization methods (such as L1 and L2 regularization) are used to prevent the model from overfitting.

[0072] During the training process, use the validation set data to verify the model. By observing the performance metrics (such as accuracy, recall, F1 value, etc.) of the model on the validation set, determine whether the model has overfitting or underfitting phenomena. If the model performs well on the training set but poorly on the validation set, it indicates that the model may be overfitting. At this time, measures such as increasing the regularization intensity and reducing the network complexity can be taken for optimization. If the performance of the model on both the training set and the validation set is not ideal, it indicates that the model may be underfitting, and it is necessary to adjust the model structure or increase the amount of training data, etc. After multiple adjustments and optimizations, until the model reaches a satisfactory performance on the validation set.

[0073] The output module is used to output a personalized childbirth risk assessment report according to the prediction result of the risk assessment model.

[0074] Specifically, according to the prediction result obtained by the evaluation module, the output module will generate a detailed and personalized childbirth risk assessment report. The report not only includes clear classifications of childbirth risk levels, such as low risk, medium risk, high risk, etc., but also gives specific risk factor analyses for different risk levels. For example, if the evaluation result is high risk, the report will specifically point out which specific factors, such as abnormal fetal heart rate and maternal pelvic stenosis, have led to the increased risk.

[0075] To facilitate a more intuitive understanding of the evaluation results by medical staff and parturients, the output module also has a visualization display function. For some key data, such as the changing trends of uterine contraction frequency and intensity, and the change of cervical dilation degree over time, etc., they will be presented in the form of charts. For example, a line chart is used to show the change of fetal heart rate over a period of time, and medical staff can quickly understand whether the fetal heart rate is stable and whether there are abnormal fluctuations through the chart.

[0076] Embodiment 2 is basically as shown in the attached Figure 2 - attached Figure 9 shown:

[0077] The difference from the above Embodiment 1 is only that a pregnancy and childbirth assistance device is provided. Through the pregnancy and childbirth assistance device provided in this embodiment, it can support the intelligent evaluation system to collect dynamic data in real time, mainly including the main body 1. In this embodiment, the main body 1 is a bed structure, and in some other embodiments, a chair structure can be adopted; a back support carrier 2, a hip support carrier 3, armrests 5 and a function rack 6 are arranged on the main body 1; both the back support carrier 2 and the hip support carrier 3 are respectively located at the top of the main body 1. In this embodiment, the hip support carrier 3 is bolted to the top of the main body 1, and the back support carrier 2 is rotatably connected to the top of the main body 1. An adjustment component (prior art, not described in detail here) for adjusting the deflection angle of the back support carrier 2 is also arranged between the back support carrier 2 and the main body 1. A sound collection unit 7 for obtaining the pain sound of the parturient is arranged on the back support carrier 2. In this embodiment, the sound collection unit 7 is a microphone. Leg brackets 4 are respectively arranged on both sides of the hip support carrier 3. Specifically, the leg brackets 4 include an arc-shaped backing plate for supporting the legs and a bracket for supporting the arc-shaped backing plate. A first pressure sensor for collecting the pressure of the parturient's legs is arranged on the leg brackets 4. The first pressure sensor is specifically installed on the inner side of the arc-shaped backing plate (i.e., the side in contact with the parturient's calf); the armrests 5 are welded and fixed to both sides of the main body 1. A second pressure sensor 501 for collecting the hand pressure of the parturient and a humidity sensor for collecting the hand sweat condition are arranged on the armrests 5. The function rack 6 is bolted to one side of the main body 1. A fetal heart rate monitor for monitoring the fetal heart rate, a Doppler ultrasound detector for detecting the cervical dilation degree and speed and the pelvic opening degree, and a uterine contraction monitor for detecting the uterine contraction frequency and intensity are placed on the function rack 6.

[0078] It also includes a control unit; the control unit is used to comprehensively judge the pain condition of the parturient based on the information of the sound collection unit 7, the information of the humidity sensor, and the information of the first pressure sensor and the second pressure sensor 501, and comprehensively judge the physical strength condition of the parturient based on the information of the first sensor and the second pressure sensor 501.

[0079] Specific implementation process: During childbirth, the parturient lies on the back support carrier 2, and the hip support carrier 3 provides the force to lift the parturient's hips. The parturient separates her feet and places them on the leg brackets 4 respectively. Each detection device (such as a fetal heart monitor, a uterine contraction monitor, etc.) on the function frame 6 is attached to the parturient's abdomen, and the doctor collects the degree of pelvic opening of the parturient through a Doppler ultrasound detector. The sound collection unit 7 monitors and collects the pain sounds emitted by the parturient during childbirth in real time, and the humidity sensor continuously monitors the sweating condition of the parturient's hand. The first pressure sensor accurately collects the pressure data exerted by the parturient's leg on the arc-shaped cushion plate, and the second pressure sensor 501 synchronously collects the pressure information exerted by the parturient's hand on the armrest 5.

[0080] All kinds of data collected by these devices will be transmitted to the control unit in real time. After receiving the data, the control unit will immediately start the algorithm program preset inside it. On the one hand, based on the information of the sound collection unit 7, the information of the humidity sensor, and the information of the first pressure sensor and the second pressure sensor 501, the pain condition of the parturient is comprehensively judged. For example, when the sound collection unit 7 captures pain sounds with high decibels and high frequencies, at the same time the humidity sensor detects an increase in sweating of the hand, and the first and second pressure sensors 501 detect large fluctuations in pressure, the control unit will determine that the parturient is in a relatively strong pain state. On the other hand, based on the information of the first sensor and the second pressure sensor 501, the physical strength of the parturient is comprehensively judged. If the pressure detected by the two pressure sensors continues to weaken and the fluctuation range becomes smaller, the control unit may judge that the physical strength of the parturient is gradually decreasing.

[0081] Meanwhile, the fetal heart monitor on the function frame 6 continuously monitors the fetal heart rate, and the uterine contraction monitor records the frequency and intensity of uterine contractions in real time, providing key data support for medical staff to judge the progress of childbirth. The Doppler ultrasound detector is also working continuously, accurately detecting the degree and speed of cervical dilation, the degree of pelvic opening, and transmitting these data to the control unit in time. After integrating and analyzing all the data, the control unit synchronously feeds back the results to the intelligent evaluation system for pregnancy and childbirth, enabling the evaluation system to more accurately evaluate the childbirth risk of the parturient based on these real-time and comprehensive dynamic data.

[0082] The difference between Example 3 and the above Example 2 is only that: a massage chamber 201 is provided on the back support carrier 2. Preferably, an elastic cushion layer 202 is adhesively fixed to the top of the massage chamber 201, a massage component is arranged in the massage chamber 201, and the control unit is also used to control the operation of the massage component based on the pain condition of the parturient. Specifically, in combination with the attached Figure 5 and the attached Figure 6As shown, the massage component includes a spherical segment carrier 204 and an annular carrier 205; the spherical segment carrier 204 is located above the annular carrier 205, and a sliding mechanism is arranged between the spherical segment carrier 204 and the annular carrier 205. The sliding mechanism is used to realize the relative sliding of the spherical segment carrier 204 in the direction away from the annular carrier 205. In this embodiment, the sliding mechanism is a plurality of telescopic shafts 213. The telescopic shafts 213 are circumferentially arranged at the bottom of the spherical segment carrier 204, and the bottoms of the telescopic shafts 213 respectively penetrate through the annular carrier 205 and are slidably matched with the annular carrier 205.

[0083] A plurality of rotary support components are circumferentially arranged between the annular carrier 205 and the bottom of the massage chamber 201. In this embodiment, a total of 4 groups of rotary support components are provided. The rotary support components are used to drive the annular carrier 205 to perform circumferential movement; specifically, in combination with the attached Figure 6 and the attached Figure 7 As shown, the rotary support component includes a connecting rod 208; rotary supports 207 are arranged at both ends of the connecting rod 208; the rotary support 207 includes a rectangular frame 2071; first rotating shafts 2072 are respectively welded and fixed on both sides of the rectangular frame 2071, and a second rotating shaft 2073 is welded and supported inside the rectangular frame 2071. The directions of the first rotating shaft 2072 and the second rotating shaft 2073 are perpendicular. The first rotating shafts 2072 are respectively rotatably connected to bases 206. In this embodiment, the base 206 is of a "concave" shape structure, and the bases 206 are respectively fixed to the bottom of the annular carrier 205 and the bottom of the massage chamber 201 by bolts; on one side of any two bases 206 in the vertical direction, a driving member is arranged. The driving member is used to drive the first rotating shaft 2072 to rotate. In this embodiment, the driving member is a stepping motor 209, and the output shaft of the stepping motor 209 is coaxially welded and fixed to the first rotating shaft 2072.

[0084] A lifting component is also arranged at the center of the bottom of the massage chamber 201. The lifting component is used to drive the spherical segment carrier 204 to perform lifting movement.

[0085] Specifically, the lifting component includes a hydraulic cylinder 210. In this embodiment, the hydraulic cylinder 210 is located at the center of the annular carrier 205; the fixed end and the output end of the hydraulic cylinder 210 are respectively rotatably connected to the bottom of the massage chamber 201 and the bottom of the spherical segment carrier 204. In this embodiment, the fixed end and the output end of the hydraulic cylinder 210 both adopt the above-mentioned rotational connection method of the connecting rod 208. In some other embodiments, a spherical hinge method can be adopted.

[0086] Specific implementation process: When the control unit determines that the pain of the parturient is relatively severe, it will activate the massage components in the massage chamber 201 on the back support carrier 2. At this time, the control unit simultaneously drives the two stepping motors 209 and the hydraulic cylinder 210 to operate. The stepping motors 209 drive the first rotating shafts 2072 in the two vertical directions to rotate respectively. The rotation of the first rotating shafts 2072 drives the connecting rods 208 to rotate, and the rotation of the connecting rods 208 drives the annular carrier 205 to perform a circumferential motion. The annular carrier 205 drives the spherical segment carrier 204 to move synchronously through the telescopic shaft 213. At the same time, the output shaft of the hydraulic cylinder 210 will push the spherical segment carrier 204 to move up and down reciprocally, so as to drive the spherical segment carrier 204 to perform an annular lifting movement to massage the back of the parturient in all directions. The control unit controls the massage range of the spherical segment carrier 204 by controlling the rotation angle of the stepping motor 209, and adjusts the massage intensity by controlling the lifting height of the hydraulic cylinder 210.

[0087] The difference between Embodiment 4 and the above-mentioned Embodiment 3 is only that a hot compress component is further provided on the spherical segment carrier 204, and the hot compress component is used to perform hot compress treatment on the back of the parturient. Specifically, in this embodiment, the hot compress component includes a heat generating layer 215 opened on the top of the spherical segment carrier 204. In this embodiment, the heat generating layer 215 and the spherical segment carrier 204 are integrally designed, and the spherical segment carrier 204 is made of heat-insulating material; a plurality of compression pipes are opened in the heat generating layer 215, and a heat conducting plate 203 is welded and fixed on the top of the heat generating layer 215; a plurality of sealing grooves 211 are circumferentially opened in the inner circumference of the annular carrier 205, and pistons 212 are slidably fitted in the sealing grooves 211; in this embodiment, the sliding mechanism includes a plurality of telescopic shafts 213, and the telescopic shafts 213 correspond to the sealing grooves 211 one by one. The bottoms of the telescopic shafts 213 are all embedded in the sealing grooves 211 and welded and fixed to the pistons 212. The telescopic shafts 213 are all slidably fitted with the annular carrier 205, and the tops of the telescopic shafts 213 are welded and fixed to the spherical segment carrier 204, combined with the attached Figure 6 and attached Figure 8 As shown, connecting channels are opened in the telescopic shafts 213, and the connecting channels communicate the sealing grooves 211 (the area above the pistons 212) with the compression pipes. Specifically, a main channel 214 is further opened in the spherical segment carrier 204. The connecting channels converge on the main channel 214 and communicate with the compression pipes through the main channel 214; the compression pipes are of the Tesla valve pipe 216 structure, and the flow rate of air decreases after entering the Tesla valve pipe 216.

[0088] Specific implementation process: When the spherical segment carrier 204 is in the lifting process, the telescopic shaft 213 will drive the piston 212 to reciprocate up and down, continuously squeezing the air in the sealing groove 211 into the compression pipeline (constantly doing work on the air). Since the compression pipeline adopts the Tesla valve pipeline 216 structure, the flow rate of the air decreases after entering, and it accumulates and rubs continuously in the narrow pipeline, thereby generating heat. These heats are evenly transferred to the back of the parturient through the heat conduction plate 203 welded and fixed to the top of the heat generation layer 215, achieving the hot compress effect.

[0089] The difference between Example 5 and the above Example 4 is only that a diversion groove is also provided on the hip support carrier, and the diversion groove is communicated with a body fluid detection component; combined with Fig. Figure 3 , Fig. Figure 5 and Fig. Figure 9 As shown, the body fluid detection component includes a drawer. In this embodiment, a sliding groove for the drawer to slide is provided on the hip support carrier, and the drawer is hidden in the hip support carrier through the sliding groove; a detection groove is provided in the drawer, and a blood detection unit and a body fluid detection unit are provided in the detection groove. The body fluid detection unit is used to collect the body fluid content in the detection groove. Specifically, the body fluid detection unit includes a pair of capacitor plates, a floating block, and a control circuit for detecting the distance between the capacitor plates. The floating block is slidably matched with the inner wall of the detection groove. One of the capacitor plates is adhesively fixed to the side wall of the detection groove, and the other capacitor plate is adhesively fixed to the top of the floating block. The blood detection unit is used to detect the blood content in the body fluid. Specifically, the blood detection unit includes a laser emitter and a receiver, and the laser emitter and the receiver are respectively located in the opposite side walls of the detection groove; the control unit is also used to judge the amniotic fluid content based on the body fluid content and the blood content; further includes an early warning module, and the early warning module is used to judge whether the parturient needs a cesarean section based on the amniotic fluid content and the blood content, and give an early warning of the body fluid loss situation of the parturient.

[0090] Specific implementation process: When the parturient is in labor, the doctor pulls out the drawer from the hip support carrier. The body fluids (including amniotic fluid, blood, sweat, etc.) generated during the parturient's labor process will flow into the detection groove from the diversion groove. As the body fluid accumulates, the floating block will rise accordingly, and the distance between the floating block and the fixed capacitor plate changes. The control circuit calculates the body fluid content in the detection groove by monitoring the change in the distance between the capacitor plates. At the same time, the laser emitter emits light to the body fluid in the detection groove, and the receiver captures the spectral changes of reflection or transmission. By analyzing the spectral characteristics, especially the absorption characteristics of heme, the blood detection unit can estimate the blood content.

[0091] The control unit integrates the data of the body fluid content and the blood content, and further analyzes the amniotic fluid content. If the test result shows that the blood content is higher than the preset blood warning content, or the body fluid loss exceeds the preset body fluid loss warning content, the warning module will determine that the parturient really needs an emergency cesarean section and issue a warning signal. The warning signal includes a sound alarm, a light prompt or a warning message displayed on the screen, reminding the medical staff to pay attention and take corresponding measures.

[0092] The above are only embodiments of the present invention, and common knowledge such as specific structures and / or characteristics known in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent. The protection scope required by this application shall be subject to the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
