摘要：An improved spacer (10) for use in administering an aerosol medication to apatient includes a spacer body member (30) having a cylindrical wall (50) defining agenerally hollow chamber (56), and a patient delivery member (20) in fluid communicationwith the chamber (56), through which medication can be delivered to the patient and amedication inlet (40). The patient delivery member (20) includes a mouthpiece (21)through which the patient can inspire medication from the chamber (56) and expire gases.An inspiratory valve (32) is coupled between the mouthpiece (21) and the chamber (56).The inspiratory valve (32) is configured for opening on inspiration by the patient, andclosing upon expiration by the patient. An expiratory valve (23) is coupled between themouthpiece (21) and an expiratory outlet (24) external of the chamber (56). The

expiratory valve (23) is configured for opening upon expiration by the patient, and closingupon inspiration by the patient. The medication inlet (40) is in fluid communication withthe chamber (56) through which medication can be introduced to the chamber (56). Themedication inlet (40) includes a retaining means (44 or 46) for retaining a medicationdelivery device on a medication inlet housing member (41). The mouthpiece (21) isconfigured to enable the fitting of standard adult and child face masks and standardconnectors with either male or female international taper fittings. The medication inlet

housing (41) can include at least one additional medication inlet (43) that allows thesimultaneous administration of other gases such as oxygen and/or aerosol medication. Amodified spacer (210) in which the inspiratory and expiratory valves are absent, is used forintroducing aerosol medication into a breathing circuit. The expiratory valve is replacedby closure disk (23b), and retaining means 46 is used in lieu of retaining spring 44.
