摘要： An improved aerosol medication delivery apparatus and system. The aerosol medication delivery apparatus includes a canister-holding portion and a chamber housing. The canister-holding portion has a receptacle for receipt of a pMDI canister containing a medication and a propellant to provide the aerosol medication delivery system. The canister-holding portion has a discharge orifice communicating with the receptacle to direct an aerosol into an interior of the chamber housing at an input end thereof. The chamber housing also has an output end from which medication can be withdrawn by inhalation by a patient. According to one aspect, the aerosol delivery system includes a containment baffle located at the output end of the chamber housing to partially block the output. According to another aspect, the canister-holding portion and the chamber housing are coupled together by a mechanism that provides for the canister-holding portion to be retracted into the chamber housing for storage. The coupling mechanism also allows the canister-holding portion to be extracted from its storage position in the chamber housing and pivoted into position for use when dispensing medication. In another aspect, an aerosol medication apparatus includes a chamber housing with an input end to receive the discharge of a medication from a pMDI canister and an output end including a containment baffle that partially blocks the output end. The pMDI canister may be received in an elastomeric backpiece that is adapted to accommodate various sizes of actuator boot mouthpieces.

摘要翻译： 改进的气溶胶药物输送装置和系统。 气溶胶药物输送装置包括罐保持部分和腔室壳体。 罐保持部分具有用于接收含有药物和推进剂的pMDI罐的容器，以提供气溶胶药物输送系统。 罐保持部分具有与容器连通的排出孔，以将烟雾引导到其壳体的输入端的内部。 腔室还具有输出端，药物可由该输出端吸入患者体内。 根据一个方面，气溶胶输送系统包括位于腔室壳体的输出端处以部分地阻挡输出的容纳挡板。 根据另一方面，罐保持部分和腔室壳体通过机构联接在一起，该机构提供将容器保持部分缩回到腔室中用于储存。 联接机构还允许罐保持部分从其在容器壳体中的存储位置提取并且枢转到用于分配药物时使用的位置。 在另一方面，一种气溶胶药物装置包括具有输入端的腔室壳体，用于接收来自pMDI罐的药物的排出以及包括部分阻塞输出端的容纳挡板的输出端。 pMDI罐可以被接收在适于容纳各种尺寸的致动器引导嘴的弹性体背部件中。

摘要： A mask is provided for the inhalation of medication, such as asthmatic medication. The mask is molded of a resilient plastic or rubber material and has a central through opening and includes an open front portion adapted to receive an aerosolization chamber which receives medication from a metered dose inhaler. A sidewall expands outwardly from the open front portion and is adapted to fit sealingly on a face covering the mouth and nose. The sidewall is provided with an extension to accommodate the nose. A one-way exhalation valve is provided in the mask, preferably at the far end of the nose accommodating extension for conveying exhaled air to the outside, and preventing entrance of outside air therethrough into said mask.
