Abstract
Description
Technical Field
[0001] This invention relates to the field of medical auxiliary technology, specifically to an infusion monitoring method, system, and mobile terminal based on a mobile terminal. Background Technology
[0002] Intravenous infusion is a common method of drug administration in clinical treatment. During infusion, it is necessary to monitor the infusion rate and remaining fluid volume in real time so that medical staff or the patient can be notified in time before the infusion is completed to prevent air from entering the bloodstream or blood backflow. Currently, infusion monitoring mainly relies on manual visual inspection, which has the following disadvantages: It requires frequent observation by medical staff or patients, which is labor-intensive; Difficult to observe at night or in poor lighting conditions; Medical staff are prone to negligence when they are busy; The remaining infusion time cannot be accurately calculated.
[0003] Existing infusion monitoring devices are mostly dedicated hardware, which are expensive, not portable, and have limited functionality, failing to meet the daily needs of ordinary patients. Summary of the Invention
[0004] The purpose of this invention is to provide an infusion monitoring method, system, and mobile terminal to solve the problems of infusion monitoring relying on manual labor, low efficiency, and high cost in the prior art.
[0005] To achieve the above objectives, the present invention provides an infusion monitoring method applied to a mobile terminal, comprising the following steps: Step S101: Infusion volume setting It receives infusion volume data input by the user, or identifies the infusion volume data by taking an image of the infusion bottle / bag. When the automatic identification result is inaccurate, the user can manually adjust it.
[0006] Step S102: Infusion rate detection The video of droplets falling in the infusion tube is recorded by the camera of a mobile terminal. The number of droplets per unit time is calculated by video analysis algorithm, thereby calculating the infusion rate.
[0007] Step S103: Calculation of infusion time The total infusion time is calculated based on the infusion volume and infusion rate, and a countdown is automatically started.
[0008] Step S104: Real-time monitoring and alerts The remaining infusion volume and remaining infusion time are updated in real time. When the remaining infusion time or remaining fluid volume is less than a set threshold, the user is alerted via vibration and / or sound.
[0009] Furthermore, the method also includes: During the infusion process, users can re-record the video of the droplets falling at any time to update the infusion rate; Based on the updated infusion rate and the volume already infused, recalculate the remaining infusion time and remaining fluid volume; Users can manually adjust the remaining fluid volume, and the system will recalculate the remaining infusion time based on the adjusted volume. Attached Figure Description
[0010] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0011] Figure 1 A flowchart illustrating an infusion monitoring method, system, and mobile terminal based on a mobile terminal, provided in an embodiment of this application; Figure 2 A schematic diagram of an infusion monitoring method, system, and mobile terminal based on a mobile terminal provided in this application embodiment; Figure 3 A schematic diagram of an infusion monitoring method, system, and infusion capacity setting module of a mobile terminal based on a mobile terminal, provided for embodiments of this application; Figure 4 A schematic diagram of an infusion monitoring method, system, and infusion rate detection module of a mobile terminal based on a mobile terminal, provided for embodiments of this application; Detailed Implementation
[0012] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0013] 1. Infusion volume setting module like Figure 3 As shown, this module provides two infusion volume setting methods: Manual setting: Users can directly input the infusion volume using the numeric keypad or slider; Automatic recognition: The system uses the mobile terminal's camera to capture images of infusion bottles or bags, identifies the volume markings (such as "500mL", "250mL", etc.) using OCR technology, and converts them into volume data usable by the system.
[0014] Manual adjustment function: When the automatic recognition result is inaccurate, users can directly modify the capacity value on the recognition interface to ensure the accuracy of the capacity data.
[0015] 2. Infusion rate detection module like Figure 4 As shown, this module detects the infusion rate through the following steps: Use the mobile terminal's camera to focus on the droplet cavity of the infusion tube; Record a video of a specified duration (e.g., 10 seconds); Use image processing algorithms to identify droplets in video frames; Calculate the number of droplets per unit time; The infusion rate (mL / h) is calculated based on the standard volume of the droplet (approximately 0.05 mL / drop by default, which can be adjusted).
[0016] 3. Infusion Time Calculation Module This module calculates the total infusion time based on a formula: Total infusion time (minutes) = Infusion volume (mL) ÷ Infusion rate (mL / h) × 60 After the calculation is completed, the system will automatically start a countdown and display the remaining infusion time and remaining fluid volume on the main interface.
[0017] 4. Monitoring and Alert Module This module provides the following functions: The remaining infusion time and remaining fluid volume are displayed in real time. Allows users to set reminder thresholds (such as 5 minutes remaining or 10 mL remaining). When the alert threshold is reached, the mobile terminal's vibrator and speaker are triggered to issue an alert. It provides an infusion rate adjustment record, and users can view historical adjustment records.
[0018] 5. Adjustment and recalculation of infusion rate like Figure 2 As shown, if medical staff adjust the infusion set regulating valve during the infusion process, the user can update the infusion rate by following these steps: Click the "Retest" button; Re-record the video of the droplets falling; The system recalculates the remaining infusion time and remaining fluid volume based on the new infusion rate and the volume already infused.
[0019] The above description is merely one specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
