摘要:针对现有助老药箱存在智能化程度不高、功能单一等缺点,无法有效解决独居老人定时定量吃药的问题,设计了CareKit助老药箱,包含常用的液体药部分、颗粒药部分、片装药部分。液体药部分采用自适应夹持七杆机构与螺杆螺母组合的变胞机构,实现液体药瓶的夹紧、倾斜倒药;螺母旋转带动六杆机构实现夹紧瓶盖、继续转动变化为三构件机构实现瓶盖拧开。颗粒药部分设计槽轮机构依次实现取药袋、夹持剪切、倾倒药袋、杯装药退出四个动作。片状药部分由双转盘结构与风机吸气配合,按量取出预存的药片。增设一键紧急呼叫以应对老人突发事故。CareKit助老药箱很好地解决了独居老人定时定量吃药问题,具有较好的应用前景。

Abstract:The existing smart medicine box has some disadvantages such as low intelligence and single function, which cannot effectively ensure regular and quantitative medication for the elderly living alone. In order to solve the problem, this paper innovatively designs a 'CareKit' medicine box which consists of three parts to contain the commonly used liquid medicine, particle medicine and tablets respectively. The part for liquid medicine adopts the metamorphic mechanism of adaptive clamping seven-bar mechanism and screw nut combination to realize the clamping and tilting of the liquid medicine bottle. The nut rotation drives the 6-bar mechanism to clamp the cap and continues to rotate and change to the 3-component mechanism to realize the cap opening. The part for particle medicine has a groove wheel mechanism to achieve the four actions of taking the bag, clamping and cutting the bag, dumping the bag, and exiting the cup in sequence. The part for tablet combines the fan suction with the double turntable structure and the reserved tablets are taken out according to the quantity. Emergency call button is added to prevent accidents for the elderly. The CareKit medicine box solves the problem of regular and quantitative medication for the elderly living alone and has a good application prospect.
Key words:elderly medicine box;metamorphic mechanism;adaptive clamping mechanism;modular design
