Description

Technical Field

[0001] This invention relates to the field of intelligent medical auxiliary equipment technology, specifically to an intelligent doll and its interaction method suitable for maternal and child health hospitals, children's hospitals, and community health service centers, used for emotional comfort and automatic collection of physiological parameters during children's medical treatment. Background Technology

[0002] Children often experience fear, crying, and resistance to examinations during medical visits, leading to low cooperation, inaccurate data, and low efficiency in medical and nursing work during routine physical examinations such as height, weight, and temperature measurement.

[0003] In existing technologies, emotional soothing and health monitoring functions operate independently. Soothing methods often rely on manual intervention or ordinary toys, while health monitoring depends on traditional medical equipment. The two lack effective coordination, resulting in limited soothing effects. Furthermore, the timing of monitoring is passive, requiring medical staff to manually assess the child's emotional state and manually activate the device, easily missing the optimal window for the child's cooperation when their emotions are stable. In addition, existing solutions lack closed-loop control logic; if a child experiences emotional fluctuations during monitoring, the monitoring process must be interrupted, rather than automatically reverting to soothing mode, leading to a break in the monitoring process. Moreover, children have low levels of self-participation, relying entirely on medical staff for operation, resulting in a poor patient experience.

[0004] A search revealed significant shortcomings in existing technologies. For example, a smart toy rocking horse integrating heart rate, body temperature, and weight sensors only detects simple physiological parameters and lacks a mechanism for linking emotion perception with tiered soothing; a child soothing method based on facial recognition is not integrated with health monitoring equipment and cannot automatically trigger detection when the child's emotions are stable. None of the existing technologies have achieved a closed-loop control system of "emotion grading—tiered soothing—calm detection—fluctuation regression," making it difficult to meet the actual needs of pediatric physical examinations in medical settings. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of separation between soothing and detection, passive detection timing, easy breakage of detection process, and low cooperation of children in the existing technology. It provides a closed-loop linkage intelligent doll for children's health detection and soothing in medical scenarios and its interaction method, which realizes automatic emotional soothing, automatic detection of calm state, and automatic retraction and soothing during fluctuations in detection, thereby improving children's cooperation in medical treatment, accuracy of detection data and efficiency of medical care. Technical solution

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A smart doll for children's health monitoring and comfort in medical settings includes the doll itself, a main control module, an emotion perception module, a health monitoring module, a comfort execution module, and a data interaction module.

[0007] The main control module has a built-in state machine for implementing closed-loop logic control.

[0008] The emotion perception module includes a facial image acquisition unit and a full-body touch sensing unit, which are used to integrate facial expression, limb struggle, and touch pressure change signals to output four levels of emotion signals: crying, irritability, calmness, and pleasure.

[0009] The health detection module integrates an ultrasonic height sensor, a pressure weight sensor, and an infrared body temperature sensor, which are respectively placed on the top of the doll's head, bottom, and palms.

[0010] The soothing execution module includes a voice soothing unit and a gesture / expression unit.

[0011] The data interaction module is used to encrypt and upload the detection data to an external system.

[0012] The closed-loop control logic of the main control module is as follows: when a crying or irritable emotional signal is received, health detection is prohibited and graded soothing is triggered; when the child's emotions remain calm for ≥20 seconds, the health detection module is automatically started to collect height, weight, and body temperature simultaneously; if the child's emotions fluctuate during the detection process, the detection is immediately paused and returned to the soothing loop, and the detection continues after the emotions stabilize.

[0013] A method for interactive health monitoring and reassurance of children in a medical setting includes the following steps: S1: The emotion perception module collects facial images and touch pressure signals, performs multimodal fusion, and outputs four levels of emotional states: crying, irritability, calmness, and pleasure. S2: If the condition is identified as crying or irritable, implement graded soothing and do not initiate health checks; S3: If the state is identified as calm and lasts for ≥20 seconds, automatically start the synchronous collection of height, weight, and body temperature; S4: If emotional fluctuations occur during the testing process, pause the testing and revert to the calming procedure; S5: After the test is completed, the data is encrypted and synchronized to the hospital system and the parents' terminal.

[0014] The beneficial effects of this invention are as follows: It pioneered a closed-loop linkage mechanism of "emotional grading - graded soothing - calm detection - fluctuation regression", which fundamentally solves the problems of separation between soothing and detection and easy process interruption; It automatically identifies stable periods and initiates testing without manual intervention, improving data accuracy and healthcare efficiency; During the testing process, emotional fluctuations can be automatically reversed and calmed, ensuring a continuous and uninterrupted process. Doll-like interactive design reduces children's fear of medical treatment and enhances their sense of participation and medical experience; The modular structure is adapted to medical scenarios, making it easy to deploy and scale up.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to specific embodiments.

[0018] In this embodiment, the emotion perception module adopts a multimodal fusion recognition method, inputs facial expression features and touch pressure timing signals, and outputs four levels of emotions: crying, irritability, calmness, and pleasure.

[0019] Example 1: A 3-year-old child cried and resisted vaccination. Medical staff placed the smart doll of this invention in front of the child. The emotion perception module identified "crying," and the main control module triggered tiered soothing: playing gentle nursery rhymes and controlling the doll to perform waving gestures. After about 1 minute, the child calmed down and remained calm for 25 seconds. The main control module automatically started a health check, with the ultrasonic height sensor, pressure and weight sensor, and infrared temperature sensor simultaneously collecting data. If the child's emotions fluctuated slightly during the process, the system immediately paused the check and switched to a story-based soothing mode, resuming the check once the child had calmed down. After the check was completed, the data was encrypted and uploaded to the hospital system and the parents' end via the data interaction module. The check data is used only for growth and development assessment and not for disease diagnosis.

[0020] Example 2: A 5-year-old child undergoes a growth and development checkup. The emotion perception module initially identifies the child as "irritable," and the main control module executes voice guidance and head-nodding gestures to soothe them. After the child remains calm for 30 seconds, the system automatically starts synchronous detection and generates a growth and development record. If slight agitation occurs during the detection, the detection is immediately paused and a nursery rhyme is played to soothe the child. Once the child calms down, the detection continues, and the data is synchronized to the community health record system.
