Embodiment 1

[0046] Such as Figure 1 to Figure 3 As shown, a hand hygiene supervision system includes an identity authentication module, an action acquisition module and a judgment module;

[0047] The identity authentication module is used to identify the identity information of the person to be detected, and starts the action acquisition module after the identification is successful;

[0048] The motion acquisition module includes a sensing device, which is placed on the body of the person to be detected, and is used to obtain the motion data generated when the person to be detected washes his hands, and performs static error calibration on the motion data and transmits it to the judgment module;

[0049] The judging module includes a processing chip, which brings the calibrated data into the action algorithm. The action algorithm includes a motion direction algorithm and a running track algorithm, which are used to judge whether the action is a trigger action, and finally judge whether...

Embodiment 2

[0076] In this embodiment, the model of the six-axis motion processing unit is MPU6500, which is placed in the badge of the medical worker;

[0077] When the medical staff wearing the badge enters the ward, the badge will turn on the gyroscope sensor and the acceleration sensor for data collection, and the collected angular velocity and acceleration of the X, Y, and Z axes will be processed and converted into Quaternion data, and then these acceleration, angular velocity and quaternion data will be sent to the buffer queue through the I2C interface at a frequency of 200Hz; then the processing chip MSP430 will read data from the buffer queue at a frequency of 300Hz; finally read Get the angular velocity and acceleration data and eliminate random noise through Kalman filter, and then integrate the filtered acceleration data to obtain the motion trajectory; convert the quaternion data into Euler angles (pitch angle Pitch, roll angle Roll angle) by quaternion algorithm , yaw angle...

Embodiment 3

[0105] Embodiment 3 is roughly the same as Embodiment 2, the difference is:

[0106] When the medical staff reaches out to hang the liquid bottle, the coordinates of the badge will change to a certain extent, forming a short-distance movement trajectory, and the pitch angle will also form a certain corner trajectory. Through the comprehensive judgment of these two trajectories, it can be realized. Judgment of reaching out to hang the bottle, after recognizing that the medical staff is reaching out to hang the liquid bottle, the processing chip will change from the clean state to the clean state, and the hand hygiene reminder will be given when the medical staff performs other operations;

[0107] When the medical staff shakes due to injection or shaking the medicine, the Z-axis of the body coordinates will change accordingly. When the change of the other two axes is less than a certain threshold and the change of the Z-axis is greater than the threshold, it will be judged as a ...

Abstract

The invention relates to the technical field of hygiene monitoring, and discloses a hand hygiene supervision system and a use method thereof, the hand hygiene supervision system comprises an identity authentication module, an action acquisition module and a judgment module; the identity authentication module is used for identifying identity information of the to-be-detected person; the action acquisition module comprises a sensing device; the judgment module comprises a processing chip and brings the calibrated data into an action algorithm, and the action algorithm comprises a movement direction algorithm and a movement track algorithm. In the aspect of medical treatment, the overall hand hygiene compliance of a hospital department provided with the system is obviously improved, the effect is stable, the infection occurrence rate is greatly reduced, and the average hospitalization date of patients is reduced; and the identity authentication module and the action acquisition module are combined, so that the movement track and the action of the medical personnel in the department can be judged more accurately, misjudgment is avoided, and the accuracy of the hand hygiene compliance rate and the user experience are improved.

Description

technical field [0001] The invention relates to the technical field of hygiene monitoring, in particular to a monitoring system for hand hygiene and a method for using the same. Background technique [0002] Bacteria carried by medical staff's hands is the main source of nosocomial infection, and direct or indirect transmission of bacteria through hands accounts for more than 30% of nosocomial infections. Strict hand washing by medical staff can reduce the carrying of pathogens and effectively cut off direct contact transmission. [0003] The U.S. Centers for Disease Control and Prevention released hand hygiene guidelines for medical institutions in October 2002, confirming the effectiveness of hand hygiene and pointing out that compared with other nosocomial infection management measures, hand hygiene is the most direct, simplest, and easiest way to reduce nosocomial infections. One of the economical and most effective measures, it plays a huge role in nosocomial infection...
