家医随访一体机作为家庭医生上门服务的核心设备，其重量设计需平衡便携性与功能完整性，既要满足医生随身携带的需求，又要保证检测项目的全面性。合理的重量控制是设备实用性的关键，直接影响上门服务的效率与医生的操作体验，同时需适配不同的使用场景（如楼梯房、老年人家中），在重量与性能之间找到最佳平衡点。
As the core equipment for home doctors' on-site services, the home doctor follow-up all-in-one machine needs to balance portability and functional integrity in its weight design, meeting the needs of doctors to carry it with them while ensuring the comprehensiveness of testing items. Reasonable weight control is the key to the practicality of equipment, which directly affects the efficiency of on-site services and the operating experience of doctors. At the same time, it needs to be adapted to different usage scenarios (such as stairwells and elderly homes) to find the best balance between weight and performance.
设备重量的构成与核心部件密切相关，硬件模块的集成度决定了基础重量。家医随访一体机通常包含检测模块（如血压计、血糖仪、心电仪）、数据处理模块（主机、显示屏）、电源模块（内置电池）及外壳结构。其中，检测模块中的金属部件（如血压计的袖带气泵、心电仪的电极接口）和显示屏的重量占比较大，一般基础模块组合后的重量在 3-5 公斤。若设备集成更多功能（如超声探头、血常规检测组件），重量会相应增加，部分多功能机型因包含小型机械传动结构（如自动进样装置），重量可能达到 6-8 公斤。外壳材质对重量影响显著，采用高强度工程塑料的设备比金属外壳轻 15%-20%，但需在抗摔性与重量间权衡，通常外壳重量占设备总重的 20%-30%。
The composition of equipment weight is closely related to the core components, and the integration degree of hardware modules determines the basic weight. The home medical follow-up all-in-one machine usually includes a detection module (such as a blood pressure monitor, blood glucose meter, electrocardiograph), a data processing module (host, display screen), a power module (built-in battery), and a housing structure. Among them, the metal components in the detection module (such as the cuff air pump of the blood pressure monitor and the electrode interface of the electrocardiograph) and the display screen account for a relatively large weight, and the combined weight of the basic module is generally 3-5 kilograms. If the device integrates more functions (such as ultrasound probes and blood routine testing components), the weight will increase accordingly. Some multifunctional models may weigh 6-8 kilograms due to the inclusion of small mechanical transmission structures (such as automatic sampling devices). The material of the shell has a significant impact on weight. Equipment made of high-strength engineering plastics is 15% -20% lighter than metal shells, but a balance needs to be made between drop resistance and weight. Typically, the weight of the shell accounts for 20% -30% of the total weight of the equipment.
便携性需求主导了重量的设计上限，上门服务场景对重量敏感。家庭医生每日需走访多个家庭，尤其是老旧小区无电梯时，设备重量直接影响携带便利性，过重会增加体力消耗，降低服务效率。行业内通常将 6 公斤作为便携性临界点，超过该重量的设备需配备辅助携带装置（如带滚轮的便携箱、可肩背的背带）。针对农村地区或远距离随访，设备重量需控制在 5 公斤以内，配合手提式设计，方便医生骑行或步行携带。部分轻量化机型通过优化结构（如折叠式显示屏、可拆卸检测模块），在保证核心功能的前提下将重量降至 3 公斤以下，适合频繁移动的服务场景，但需注意轻量化可能对设备稳定性的影响（如减少外壳厚度可能降低抗冲击能力）。
The portability requirement dominates the design limit of weight, and the on-site service scenario is sensitive to weight. Family doctors need to visit multiple households every day, especially in old residential areas without elevators. The weight of the equipment directly affects the convenience of carrying, and being too heavy can increase physical exertion and reduce service efficiency. In the industry, 6 kilograms is usually used as the threshold for portability, and equipment exceeding this weight needs to be equipped with auxiliary carrying devices (such as portable cases with rollers, shoulder straps). For rural areas or remote follow-up, the weight of the equipment should be controlled within 5 kilograms, and it should be designed to be portable for doctors to carry while cycling or walking. Some lightweight models have optimized their structure (such as foldable display screens and detachable detection modules) to reduce weight to less than 3 kilograms while ensuring core functions, making them suitable for frequently moving service scenarios. However, attention should be paid to the potential impact of lightweight on device stability (such as reducing the thickness of the casing, which may decrease impact resistance).
功能配置与重量存在一定的博弈关系，不同服务需求对重量的容忍度不同。基础型家医随访一体机（仅包含血压、血糖、心电检测）重量较轻，适合常规慢病随访，能满足 80% 以上的基础检测需求，重量多在 3-4 公斤。进阶型设备增加了肺功能检测、血氧监测等模块，重量升至 5-6 公斤，适用于需要综合评估的患者（如慢阻肺、心脏病患者）。高端机型集成了小型化验组件（如尿常规检测），因包含试剂存储舱和温控模块，重量达 7-8 公斤，主要用于特殊病例的上门诊断，这类设备通常配备拉杆式便携箱，以缓解携带压力。功能与重量的平衡需结合服务人群特点，若服务对象以老年人为主（需多项基础检测），中等重量（4-5 公斤）的设备更实用。
There is a certain game relationship between functional configuration and weight, and different service requirements have different tolerances for weight. The basic home medical follow-up all-in-one machine (including only blood pressure, blood glucose, and electrocardiogram testing) is lightweight and suitable for routine chronic disease follow-up. It can meet more than 80% of basic testing needs and weighs mostly 3-4 kilograms. The advanced device has added modules such as lung function testing and blood oxygen monitoring, weighing up to 5-6 kilograms, suitable for patients who require comprehensive evaluation (such as those with chronic obstructive pulmonary disease and heart disease). High end models integrate small laboratory components (such as urine routine testing), weighing 7-8 kilograms due to the inclusion of reagent storage compartments and temperature control modules. They are mainly used for on-site diagnosis of special cases and are usually equipped with a pull rod portable case to relieve carrying pressure. The balance between function and weight needs to be combined with the characteristics of the service population. If the service target is mainly elderly people (requiring multiple basic tests), equipment with medium weight (4-5 kilograms) is more practical.
电源设计对重量的影响具有双重性，电池容量与续航需求需协同考量。内置电池是重量的重要组成部分，容量越大（续航时间越长），电池重量越高。家医随访一体机的电池容量通常在 5000-10000 毫安时，对应重量增加 0.5-1 公斤，可支持 4-8 小时连续工作。若采用可拆卸电池设计，医生可携带备用电池，既保证续航又能减轻单次携带重量（主机重量减少 0.3-0.6 公斤）。充电方式也间接影响重量，支持快充的设备可减少电池容量需求（如 2 小时充满电），从而降低重量，但需确保随访区域有充电条件，避免因电量不足影响服务。
The impact of power design on weight has a dual nature, and battery capacity and endurance requirements need to be considered in conjunction. The built-in battery is an important component of weight, and the larger the capacity (longer the battery life), the higher the battery weight. The battery capacity of the home medical follow-up all-in-one machine is usually between 5000-10000mAh, with a corresponding weight increase of 0.5-1kg, and can support 4-8 hours of continuous operation. If a detachable battery design is adopted, doctors can carry spare batteries, which not only ensures battery life but also reduces the weight of a single carry (reducing the weight of the main unit by 0.3-0.6 kilograms). The charging method also indirectly affects weight. Devices that support fast charging can reduce battery capacity requirements (such as fully charging in 2 hours), thereby reducing weight. However, it is necessary to ensure that the follow-up area has charging conditions to avoid affecting service due to insufficient power.
