vlg Health Care

　　I. Solution Core Positioning and System Architecture

　　VLG Health Care is based on "communication hardware, centered on medical scenarios, and guided by security and compliance." Addressing the core pain points of medical institutions (hospitals, clinics, and elderly care facilities), it integrates VLG medical-grade hardware (RFID, sensors, low-power modules) with lightweight intelligent capabilities, forming a three-layer "device-edge-cloud" architecture:

　　"Device" Layer: VLG medical-grade terminals (RFID tags/readers, vital sign sensors, intelligent protective equipment), responsible for medical consumable identification, patient data collection, and medical staff location;

　　"Edge" Layer: VLG medical edge gateway (compliant with medical EMC standards), enabling local data preprocessing (such as abnormal vital sign warnings and consumable traceability matching), reducing cloud transmission pressure and privacy risks;

　　"Cloud" Layer: VLG medical data collaboration platform (or interface with hospital HIS/LIS systems), providing functions such as consumable traceability, patient monitoring, and medical staff scheduling, meeting the requirements for "traceable, controllable, and analyzable" medical data.

　　II. Core Products and Solutions (Focusing on Pain Points in Medical Scenarios)

　　1. Medical Consumables Full Lifecycle Traceability Solution

　　Core Pain Points: Risks of surgical instrument reuse, loss of high-value consumables, and chaotic management of consumable expiration dates.

　　Product Portfolio:

　　Hardware Core: VLG medical-grade HF/UHF RFID tags (compliant with ISO 13485) + desktop/mobile RFID readers + low-power NB-IoT module;

　　Software Support: VLG consumables traceability platform (interfacing with hospital HIS systems, including full-process records of warehousing, disinfection, use, and disposal);

　　Key Features:

　　RFID Tags: Made of medical-grade PET/ceramic substrate, supports 121℃ steam sterilization (30 minutes) and 254nm UV disinfection (1 hour), data storage life ≥ 5 years (suitable for long-term traceability of high-value consumables);

　　Readers: IP65 protection (alcohol-resistant), supports simultaneous identification of multiple tags (≤30 tags/second, suitable for batch inventory of surgical instruments), EMC compliant with IEC. 60601-1-2 (To avoid interference with equipment such as ECG monitors).

　　Application Logic: High-value consumables (such as cardiac stents and artificial joints) are affixed with VLG UHF RFID tags (containing batch number, expiration date, and manufacturer) at the factory. Upon arrival at the hospital, they are automatically registered using an RFID reader.

　　Before surgery, nurses use a mobile reader to scan the RFID tags on the instrument packs to confirm the quantity of instruments and the number of sterilization cycles (to prevent reuse). This data is synchronized to the surgical anesthesia system.

　　After use, consumables are marked "used" by the reader. The platform automatically sends an alert when the expiration date is approaching (e.g., 30 days remaining). An electronic ledger is generated upon disposal (compliant with medical waste management regulations).

　　Value Highlights: Surgical instrument reuse rate reduced to 0%, high-value consumable loss rate reduced from 5% to 0.2%, and consumable inventory efficiency improved by 80% (from 2 hours/pack manually to 5 minutes/pack manually).

　　2. Patient Vital Signs Monitoring and Early Warning Solution

　　Core Pain Points: High labor costs for inpatient patient monitoring, delayed detection of abnormal vital signs, and data gaps in home-based chronic disease management.

　　Product Portfolio:

　　Hardware Core: VLG medical-grade vital sign sensors (heart rate, blood oxygen, body temperature) + low-power NB-IoT module + miniature GNSS antenna (for elderly patient positioning);

　　Software Support: VLG patient monitoring platform (including real-time monitoring, abnormal warning, and data trend analysis);

　　Key Features:

　　Sensors: Uses medical-grade silicone electrodes (biocompatibility compliant with ISO 10993-1), non-invasive patch design (suitable for newborns and elderly patients), battery life ≥72 hours (single charge), data acquisition accuracy: heart rate ±1 beat/min, blood oxygen ±2%, body temperature ±0.1℃;

　　Communication Module: Supports NB-IoT low-power transmission (standby power consumption ≤5μA), weak signal areas (such as ICU wards) are enhanced by VLG signal amplifiers, data transmission success rate ≥99.8%.

　　Application Logic: Inpatients wear VLG (Vacuum-Gas Sensor) sensors (e.g., wristbands, chest patches) to collect real-time heart rate and blood oxygen data, which is then uploaded to the monitoring platform via an NB-IoT module. When a patient's blood oxygen level is ≤93% or their heart rate is >120 beats/min, the platform immediately triggers an audible and visual alarm (nurse station + mobile device) and simultaneously pushes the abnormal data to the attending physician (delay ≤30 seconds). Home-based chronic disease patients (e.g., diabetes, heart failure) periodically upload data via sensors, and the platform generates weekly/monthly trend reports, allowing doctors to remotely adjust medication plans and reduce outpatient follow-up visits.

　　Value Highlights: Abnormal sign detection time for ICU patients is reduced from 10 minutes to 30 seconds; inpatient monitoring labor costs are reduced by 40%; and the follow-up visit rate for home-based chronic disease patients is reduced by 35%.

　　3. Healthcare Staff Safety and Collaboration Solution

　　Core Pain Points: Monitoring and protection of healthcare staff in infectious disease wards, delays in emergency dispatch, and difficulties in calculating healthcare staff workload.

　　Product Portfolio:

　　Hardware Core: VLG Medical Intelligent Protective Equipment (intelligent protective suit, intelligent safety helmet) + UHF RFID positioning tags + 4G/NB-IoT dual-mode module;

　　Software Support: VLG Healthcare Collaboration Platform (including positioning dispatch, protection monitoring, and workload statistics);

　　Key Features:

　　Intelligent Protective Suit: Integrated pressure sensor (monitors the airtightness of the protective suit and alarms when damaged), temperature and humidity sensor (prevents heatstroke among healthcare staff), RFID tags (positioning accuracy ≤3 meters, zoned management of infectious disease wards);

　　Intelligent Safety Helmet: Lightweight design (weight ≤300g), built-in noise-canceling microphone (suitable for voice communication in noisy wards), high-definition camera (real-time image transmission for remote consultations), IP65 protection rating (resistant to alcohol disinfection). Application Logic: In infectious disease wards (such as COVID-19 isolation areas), medical staff wear smart protective suits. The platform monitors the pressure of the suits in real time (an alarm sounds when pressure is <5 kPa, indicating potential damage), and tracks personnel location via RFID (avoiding cross-area movement). In emergencies (such as a patient's sudden convulsions), medical staff can trigger an SOS by pressing and holding the side button on their safety helmet. The platform immediately dispatches the nearest available medical staff for support (displaying real-time location and route). The platform automatically calculates the time medical staff spend in the ward and the number of operations performed (such as IV infusions and dressing changes), generating workload reports to avoid errors from manual statistics.

　　Value Highlights: Reduces the risk of protective suit damage to medical staff by 60%, shortens emergency response time from 5 minutes to 1 minute, and increases workload statistics accuracy to 100%.

　　4. Intelligent Monitoring Solution for Medical Environments

　　Core Pain Points: Large fluctuations in operating room/ICU environmental parameters (temperature, humidity, cleanliness); medical waste storage environment exceeding standards; high energy consumption of air conditioning systems.

　　Product Portfolio:

　　Hardware Core: VLG medical-grade environmental sensors (temperature, humidity, PM2.5, formaldehyde) + WiFi 6 module (high-speed transmission) + edge gateway (local data processing);

　　Software Support: VLG environmental monitoring platform (including parameter monitoring, automatic linkage, and energy consumption analysis);

　　Key Features:

　　Sensors: Accuracy up to ±0.3℃/±2% RH for temperature and humidity, ±5μg/m³ for PM2.5; supports high-frequency data acquisition at 1 minute/time (suitable for the stringent environmental requirements of operating rooms); casing resistant to alcohol/disinfectant corrosion (compliant with medical cleaning standards);

　　Edge Gateway: EMC compliant with IEC 60601-1-2 Class B (no electromagnetic radiation interference); supports local logic judgment (e.g., automatically triggering air conditioning adjustment when temperature and humidity exceed standards). Application Logic: VLG environmental sensors are deployed in the operating room to monitor temperature (22-25℃), humidity (40-60%), and cleanliness (Class 10,000 standard) in real time. When data exceeds limits, the platform automatically triggers the air conditioning system to adjust (delay ≤1 minute). Formaldehyde sensors are installed in the medical waste storage room. When the concentration is ≥0.1mg/m³, the exhaust system is triggered, and an alert is sent to the logistics department (to prevent environmental pollution). The platform analyzes the energy consumption of environmental equipment in each department (such as air conditioning and fresh air systems) and generates energy-saving solutions (such as appropriately relaxing the temperature and humidity range during non-surgical periods) to reduce hospital energy costs.

　　Value Highlights: The compliance rate of operating room environmental parameters increased from 85% to 99%, the rate of exceeding standards in medical waste storage environments decreased to 0%, and the energy consumption of hospital environmental equipment decreased by 20%.
