Description

Technical Field

[0001] This invention belongs to the technical field of blood pressure monitoring equipment, specifically relating to a non-invasive continuous blood pressure monitoring device for predicting the risk of preeclampsia in perinatal pregnant women. Background Technology

[0002] Preeclampsia is a serious pregnancy complication that is often accompanied by abnormal fluctuations in blood pressure. If it is not identified and intervened in the early stages, it can seriously threaten the lives of both the pregnant woman and the fetus. Therefore, in the perinatal management process, early, continuous, and dynamic monitoring of the pregnant woman's blood pressure by medical institutions is of great significance for risk assessment and clinical decision-making regarding preeclampsia. Currently, in clinical prenatal examinations, a single blood pressure measurement is usually performed on the pregnant woman using a manual or electronic blood pressure monitor. However, this method only reflects the blood pressure status at a specific moment and is difficult to obtain the trend of blood pressure changes over a longer period of time, especially at night or at rest. Abnormal circadian rhythms of blood pressure (such as non-dipper blood pressure) are clinically recognized as an important early risk signal of preeclampsia. In practical clinical applications, single-measurement methods can easily lead to delayed or missed risk identification. Chinese Patent Publication No. CN221105818U discloses a blood pressure monitor that achieves blood pressure detection through a main unit, connecting tube, and wrist-arm cuff structure, and includes a storage mechanism for easy retraction and protection of the wrist-arm cuff. While this design represents an improvement in structural storage, its blood pressure detection method remains based on the traditional cuff inflation principle, primarily suitable for routine blood pressure monitoring scenarios. Furthermore, in clinical perinatal monitoring, the intermittent blood pressure monitoring method using a periodically inflated cuff still has limitations. Firstly, repeated inflation and pressurization can easily cause discomfort to pregnant women, affecting their cooperation during the examination, especially when observing blood pressure trends over extended periods, increasing the subject's tension and fatigue. Secondly, existing monitoring equipment is highly sensitive to changes in body position and limb movement during continuous monitoring, easily introducing motion artifacts that affect the stability and reliability of blood pressure data, thus limiting its clinical application in continuous perinatal risk assessment. In summary, there is a need for a non-invasive continuous blood pressure monitor for predicting the risk of preeclampsia in perinatal pregnant women, in order to solve the problems of existing technologies, such as the difficulty in non-invasive continuous and stable monitoring, the inability to accurately reflect the trend of blood pressure changes, and the difficulty for doctors to dynamically assess the risk of preeclampsia.

The damping shock absorbers 32 and springs 31 provide a certain degree of buffer protection for the entire device during use, extending the device's service life and improving the accuracy of subsequent blood pressure detection. A fourth positioning bolt 58 is installed between the bottom mounting frame 55 and the side positioning block 54 to limit the position of the support foot 57. Positioning pins for use with the casters 56 are installed on the outer side of the bottom mounting frame 55. The corresponding casters 56 are locked by the positioning pins. The support height of the corresponding support foot 57 is adjusted by tightening the fourth positioning bolt 58 until the casters 56 and support feet 57 simultaneously support the entire equipment, facilitating flexible switching between movement and support operation modes. Reinforcing inclined plates 53 are fixedly connected to the top of the bottom fixing plate 51 and around the bottom support rod 52. One side of each reinforcing inclined plate 53 is fixedly connected to the bottom support rod 52, reinforcing the connection between the bottom fixing plate 51 and the bottom support rod 52 and improving the stability of the equipment. A connecting circuit 25 is installed between the electronic detector 24 and the limiting seat 22. The top of the limiting seat 22 is threaded with symmetrically distributed first positioning bolts 23 extending into the operating table 26. The first positioning bolts 23 reinforce the connection between the limiting seat 22 and the operating table 26, facilitating adjustment of the working position and improving the stability of the equipment during actual testing. A worm gear reducer 59 is installed on the top of the bottom support rod 52.

In use, medical personnel adjust the main body 1 of the fixation frame to a suitable position and stably fix the blood pressure monitoring device 2 to the upper limb of the perinatal pregnant woman, ensuring that the blood pressure monitoring device 2 remains in continuous contact with the skin. Then, the visualization mechanism 4 is activated and the device is started. Multiple sensors installed within the blood pressure monitoring device 2 continuously collect raw physiological signals such as the pregnant woman's pulse wave while in a stable contact state. During monitoring, when the pregnant woman's upper limb experiences slight movement or external vibration, the detection buffer protection mechanism 3 absorbs and buffers the corresponding interference, reducing the impact of limb movement on signal acquisition. This maintains the relative stability of the sensor-skin contact interface, ensuring the continuity and reliability of pulse wave signal acquisition. The collected raw physiological signals are transmitted via the connecting circuit 25. The electronic detector 24 performs preprocessing such as filtering and amplification on the signal, and calculates continuous blood pressure values ​​based on pulse wave waveform characteristics and related parameters. The continuous blood pressure values ​​include indicators such as systolic blood pressure, diastolic blood pressure, mean arterial pressure, and heart rate. At the same time, the continuous blood pressure data and the diurnal variation characteristics of blood pressure are input into a preset risk prediction model to analyze and assess the risk of preeclampsia in perinatal pregnant women. The analysis results are displayed in real time through the visualization mechanism 4 in the form of blood pressure change trends, diurnal rhythm types, and risk levels, so that medical staff can dynamically observe the blood pressure status of pregnant women and use it as a reference for preeclampsia screening, follow-up, and intervention. In summary, this invention has the advantages of high detection accuracy, strong detection stability, and results that support clinical decision-making.
