    • A portable, battery-powered aspirator for use in emergency situations having an improved fluid container incorporating a recess for coiling an aspiration hose within the structural outline of the aspirator housing. A connection grommet in the housing between the container and a vaccum pump in the housing includes a stepped throughbore to alternately mate directly with a tube from the container or a different size fitting of an intermediate filter. A removable baffle in an outlet port from the pump reduces noise and vapor discharge. The pump generates a high vacuum pressure and runs efficiently to extend the usable life of the aspirator. An improved recharging unit releasably retains the aspirator on a shelf by simply sliding the aspirator straight back on guide rails. Flexible recharging terminals in the unit automatically align with angle power prongs extending from the rear of the aspirator.
    • 一种用于紧急情况的便携式,电池供电的抽吸器,其具有改进的流体容器,该流体容器包括用于将抽吸软管卷绕在抽吸器壳体的结构轮廓内的凹槽。 容器和壳体中的真空泵之间的壳体中的连接垫圈包括阶梯式通孔,以从容器或中间过滤器的不同尺寸的配件直接交替地配合管。 从泵出口的可拆卸挡板减少噪音和蒸气排放。 泵产生高真空压力并有效运行以延长吸气器的使用寿命。 改进的再充电单元通过简单地将吸气器直接滑回到导轨上将释放器可释放地保持在搁架上。 设备中的灵活充电终端自动对准从吸气器后部延伸的角度电源插脚。
