用于安全饮用，防止呛噎和摄入杂质。
专利摘要
一种安全饮用吸管具有一个细长的中空主体，其顶端形成有一个环，该环具有一个允许液体通过的孔口。孔口的大小控制最大液体流速，从而防止摄入过多液体。环的平滑轮廓防止对嘴或嘴唇造成伤害。环的大小防止其插入口中，从而防止窒息和对嘴或喉咙的可能伤害。此外，上部环的开放配置使其易于被尚未发展出精细运动技能的幼儿或患有影响手部小肌肉运动障碍的成人抓握。设置在吸管底部远端的一个过滤器可防止摄入可能存在于通过吸管消耗的液体中的种子或其他颗粒。
Original abstractA safety drinking straw has an elongated, hollow body having a loop formed at its top end, the loop having an orifice through which liquid may pass. The size of the orifice controls the maximum liquid flow rate thereby preventing excessive liquid to be ingested. The smooth contour of the loop prevents injury to the mouth or lips. The size of the loop prevents its insertion into the mouth, thereby preventing both choking and possible injury to the mouth or throat. In addition, the open configuration of the upper loop makes it easy to grasp by a young child with not yet developed fine motor skills or by an adult having a disorder that effects small motor movements of the hand. A strainer disposed at the bottom, distal end of the straw prevents ingestion of seeds or other particles possibly present in the liquid being consumed through the straw.
