在慢性病管理領(lǐng)域，隨訪包作為核心數(shù)據(jù)采集終端，其數(shù)據(jù)傳輸方式的多樣性直接決定了醫(yī)療服務(wù)的可及性與管理效率。當(dāng)前慢病隨訪包已形成無線傳輸為主、有線傳輸為輔的技術(shù)體系，并通過標(biāo)準(zhǔn)化協(xié)議與安全機(jī)制構(gòu)建起完整的醫(yī)療數(shù)據(jù)生態(tài)鏈。

　　In the field of chronic disease management, follow-up packages serve as the core data collection terminal, and the diversity of their data transmission methods directly determines the accessibility and management efficiency of medical services. The current chronic disease follow-up package has formed a technical system mainly based on wireless transmission and supplemented by wired transmission, and has built a complete medical data ecosystem through standardized protocols and security mechanisms.

　　一、無線傳輸技術(shù)矩陣

　　1、 Wireless Transmission Technology Matrix

　　藍(lán)牙傳輸系統(tǒng)

　　Bluetooth transmission system

　　作為短距離無線傳輸?shù)暮诵姆桨?，藍(lán)牙技術(shù)通過低功耗協(xié)議（BLE）實(shí)現(xiàn)設(shè)備與移動(dòng)終端的穩(wěn)定連接。隨訪包內(nèi)置的藍(lán)牙模塊可自動(dòng)識(shí)別3米范圍內(nèi)的智能手機(jī)或平板設(shè)備，建立加密傳輸通道。該技術(shù)特別適用于家庭場景，患者自主測量后，血壓、血糖等生理參數(shù)可即時(shí)同步至專用APP，數(shù)據(jù)完整率達(dá)99.8%。

　　As the core solution for short-range wireless transmission, Bluetooth technology achieves stable connection between devices and mobile terminals through the Low Energy Protocol (BLE). The built-in Bluetooth module in the follow-up package can automatically recognize smartphones or tablets within a 3-meter range and establish an encrypted transmission channel. This technology is particularly suitable for home scenarios. After patients independently measure their blood pressure, blood glucose, and other physiological parameters, they can be instantly synchronized to a dedicated app, with a data integrity rate of 99.8%.

　　Wi-Fi直連方案

　　Wi Fi Direct Connection Solution

　　配備雙頻Wi-Fi模塊的隨訪包，支持2.4GHz與5GHz雙通道傳輸。在社區(qū)衛(wèi)生服務(wù)中心等固定場所，設(shè)備可通過接入局域網(wǎng)直接上傳數(shù)據(jù)至區(qū)域健康信息平臺(tái)。該方案單次數(shù)據(jù)包傳輸速率可達(dá)866Mbps，較藍(lán)牙提升8倍，尤其適合心電圖等大容量數(shù)據(jù)的實(shí)時(shí)回傳。

　　Follow up package equipped with dual band Wi Fi module, supporting dual channel transmission of 2.4GHz and 5GHz. At fixed locations such as community health service centers, devices can directly upload data to the regional health information platform by accessing the local area network. This solution can achieve a single data packet transmission rate of 866Mbps, which is 8 times faster than Bluetooth, and is particularly suitable for real-time transmission of large capacity data such as electrocardiograms.

　　蜂窩網(wǎng)絡(luò)覆蓋

　　Cellular network coverage

　　4G/5G模塊的集成使隨訪包具備移動(dòng)通信能力。在偏遠(yuǎn)農(nóng)村或流動(dòng)人口管理場景中，設(shè)備可脫離中間設(shè)備，通過運(yùn)營商網(wǎng)絡(luò)直連云端服務(wù)器。某省級(jí)慢病管理項(xiàng)目實(shí)測顯示，5G網(wǎng)絡(luò)環(huán)境下數(shù)據(jù)傳輸延遲低于50ms，滿足遠(yuǎn)程會(huì)診對(duì)實(shí)時(shí)性的要求。

　　The integration of 4G/5G modules enables the follow-up package to have mobile communication capabilities. In remote rural areas or mobile population management scenarios, devices can be disconnected from intermediate devices and directly connected to cloud servers through operator networks. The actual measurement of a provincial chronic disease management project shows that the data transmission delay in the 5G network environment is less than 50ms, which meets the real-time requirements of remote consultation.

　　云平臺(tái)中繼模式

　　Cloud platform relay mode

　　高端隨訪包采用混合傳輸架構(gòu)，數(shù)據(jù)首先通過藍(lán)牙/Wi-Fi匯聚至邊緣計(jì)算網(wǎng)關(guān)，經(jīng)協(xié)議轉(zhuǎn)換后批量上傳至醫(yī)療云。這種分級(jí)傳輸模式既降低終端功耗，又提升數(shù)據(jù)吞吐量。某三甲醫(yī)院試點(diǎn)數(shù)據(jù)顯示，該模式使單日數(shù)據(jù)接入量提升300%。

　　The high-end follow-up package adopts a hybrid transmission architecture. Data is first converged to the edge computing gateway through Bluetooth/Wi Fi, and then uploaded to the medical cloud in batches after protocol conversion. This hierarchical transmission mode not only reduces terminal power consumption but also improves data throughput. According to pilot data from a tertiary hospital, this model has increased daily data access by 300%.

　　二、有線傳輸補(bǔ)充方案

　　2、 Supplementary plan for wired transmission

　　USB物理連接

　　USB physical connection

　　針對(duì)無網(wǎng)絡(luò)環(huán)境或設(shè)備初始化場景，隨訪包保留Type-C接口。通過專用數(shù)據(jù)線連接電腦，可實(shí)現(xiàn)數(shù)據(jù)導(dǎo)出與系統(tǒng)升級(jí)。該方案傳輸速率達(dá)5Gbps，但需人工干預(yù)，主要作為應(yīng)急備份通道。

　　For scenarios without network or device initialization, the follow-up package retains the Type-C interface. By connecting a dedicated data cable to a computer, data export and system upgrades can be achieved. This solution has a transmission rate of 5Gbps, but requires manual intervention and is mainly used as an emergency backup channel.

　　以太網(wǎng)擴(kuò)展

　　Ethernet Expansion

　　部分專業(yè)級(jí)設(shè)備配置RJ45網(wǎng)口，可直接接入醫(yī)療機(jī)構(gòu)內(nèi)網(wǎng)。這種硬連接方式通過MAC地址綁定與VLAN隔離，滿足等保2.0三級(jí)要求，適用于傳染病房等高安全需求場景。

　　Some professional level equipment is equipped with RJ45 network ports, which can directly connect to the internal network of medical institutions. This hard connection method binds MAC addresses and isolates VLANs, meeting the requirements of Level 3 of the Equal Protection 2.0, and is suitable for high security scenarios such as infectious disease wards.

　　三、傳輸安全保障體系

　　3、 Transmission security guarantee system

　　加密傳輸協(xié)議

　　Encryption Transmission Protocol

　　所有無線傳輸均采用AES-256加密，數(shù)據(jù)包封裝時(shí)加入時(shí)間戳與設(shè)備指紋，防范重放攻擊。某市疾控中心測試表明，該機(jī)制可抵御99.9%的網(wǎng)絡(luò)竊聽嘗試。

　　All wireless transmissions use AES-256 encryption, and timestamps and device fingerprints are added during packet encapsulation to prevent replay attacks. The testing conducted by a certain city's disease control center shows that this mechanism can resist 99.9% of network eavesdropping attempts.

　　雙因素認(rèn)證機(jī)制

　　Two factor authentication mechanism

　　數(shù)據(jù)接收端實(shí)施設(shè)備證書與用戶令牌雙重驗(yàn)證。當(dāng)隨訪包首次接入新網(wǎng)絡(luò)時(shí)，需通過管理平臺(tái)授權(quán)，并在APP端進(jìn)行二次確認(rèn)，確保數(shù)據(jù)流向可控。

　　The data receiving end implements dual verification of device certificates and user tokens. When the follow-up package is first connected to a new network, it needs to be authorized through the management platform and confirmed twice on the APP to ensure that the data flow is controllable.

　　傳輸質(zhì)量監(jiān)控

　　Transmission quality monitoring

　　內(nèi)置的QoS模塊實(shí)時(shí)監(jiān)測信道質(zhì)量，當(dāng)檢測到丟包率超過閾值時(shí)，自動(dòng)觸發(fā)重傳機(jī)制。在地鐵等復(fù)雜電磁環(huán)境中，該功能使數(shù)據(jù)完整率維持在95%以上。

　　The built-in QoS module monitors channel quality in real-time and automatically triggers a retransmission mechanism when the packet loss rate exceeds a threshold. In complex electromagnetic environments such as subways, this function maintains a data integrity rate of over 95%.
