Description

Technical Field

[0001] This invention relates to the field of medical and nursing equipment technology, and more specifically, to an intelligent delivery room nursing system that integrates multimodal environmental control of sound, light, and temperature. Background Technology

[0002] In modern obstetric care, the physiological comfort and psychological state of the mother have a significant impact on the delivery process and postpartum recovery. Traditional delivery room environments rely heavily on manual control, such as manually adjusting air conditioning temperature, switching lighting on and off, and playing background music, lacking the ability to dynamically respond to the individual needs of the mother. Furthermore, existing delivery room equipment is typically single-function, with each subsystem operating independently, making it difficult to achieve synergistic optimization and create a comprehensive environment conducive to natural childbirth, alleviating anxiety, and promoting maternal and infant health.

[0003] In recent years, although some studies have attempted to introduce intelligent control technology, the following problems generally exist: (1) the perception dimension of environmental parameters is singular, focusing only on temperature or light, ignoring multimodal factors such as sound and emotion; (2) there is a lack of a closed-loop feedback mechanism based on the physiological indicators and behavioral state of the parturient; (3) the differences in environmental needs at different stages of labor are not fully considered, resulting in rigid control strategies. Therefore, an intelligent delivery room care system integrating sound, light, temperature and multimodal environmental control is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the problems raised in the existing background technology. To achieve the above-mentioned objective, this invention provides the following technical solution: an intelligent delivery room care system integrating multimodal environmental control of sound, light, and temperature, comprising: a multimodal environmental sensing module for real-time acquisition of sound, light, and temperature / humidity data within the delivery room; The postpartum physiological and behavioral status monitoring module is used to acquire the postpartum woman's physiological parameters and behavioral status information; The multimodal fusion and intelligent decision-making unit is used to fuse the environmental perception data and the mother's status information, identify the current stage of labor and emotional state, and generate corresponding sound, light and temperature coordinated control strategies. The execution and interaction module is used to automatically adjust the lighting, audio playback and temperature control equipment in the delivery room according to the control strategy, and to provide a human-computer interaction interface for the mother or medical staff to intervene. In the aforementioned coordinated control strategy, the illuminance range is 10–200 lux, the color temperature range is 2200K–4000K, the ambient temperature is set between 24℃ and 27℃, and the relative humidity is maintained between 50% and 70%RH.

[0005] As a preferred technical solution of the present invention, the multimodal environment perception module includes: A sound sensor array with a sampling rate of no less than 44.1 kHz is used to collect environmental noise, maternal voices and newborn cries, and supports sound source localization and cry frequency band identification (main frequency band 300–5000 Hz). A light sensor with a range of 0–100,000 lux and a color temperature detection accuracy of ±50K is used to detect ambient illuminance, color temperature, and color rendering index (CRI≥80). Temperature and humidity sensor, temperature measurement accuracy ±0.3℃, humidity measurement accuracy ±2%RH; Optionally, an air quality sensor may also be included to detect carbon dioxide concentration (range 400–5000 ppm) or total volatile organic compounds (TVOC, range 0–1000 ppb).

[0006] As a preferred embodiment of the present invention, the postpartum physiological and behavioral status monitoring module includes: Wearable physiological monitoring devices are used to collect heart rate (normal range 60–120 bpm), heart rate variability (HRV, SDNN ≥ 50 ms is considered resting state), skin conductance (EDA, change rate > 0.5 μS / s is considered anxiety) and blood oxygen saturation (SpO2 ≥ 95%) in real time. A non-contact infrared camera with a frame rate of ≥30 fps is used to recognize the mother's facial expressions (based on FACS coding), changes in body position, and intensity of activity. The mattress integrates a pressure sensor array with no fewer than 12 zones and a sampling frequency of ≥5 Hz. This is used to monitor the frequency of turning over (<2 times / hour is considered resting), postural stability, and uterine contraction cycle characteristics (contraction intervals ≤5 minutes and lasting ≥30 minutes are considered active labor).

[0007] As a preferred technical solution of the present invention, the multimodal fusion and intelligent decision-making unit includes: a data synchronization and feature extraction module for performing time alignment and feature engineering on multi-source heterogeneous data; and a deep learning-based context recognition model for determining the current stage of labor and the emotional state of the mother. The preset environmental control strategy library stores sound-light-temperature parameter combinations for different stages of labor and emotional states; the adaptive optimization algorithm module is used to dynamically adjust the output strategy based on real-time feedback and supports manual priority overlay by medical staff.

[0008] Compared with existing technologies, the beneficial effects of this invention are as follows: By integrating multimodal environmental perception and control capabilities of sound, light, and temperature, combined with real-time analysis of the physiological and behavioral states of parturient women, this invention achieves intelligent, personalized, and contextualized management of the delivery room environment. Its main advantages include: significantly reducing anxiety and pain perception during childbirth, increasing the success rate of natural childbirth; reducing the environmental control workload of medical staff and improving nursing efficiency; supporting adaptive environmental switching across multiple stages and scenarios to meet the needs of the entire cycle from labor to postpartum recovery; ensuring the dignity of parturient women and data security through non-invasive monitoring and privacy protection design; and facilitating integration with existing hospital information systems (HIS) and intelligent ward platforms through modular system design.
