TH30835B - Compression locking mechanism for spring-operated output drives - Google Patents

Abstract

A spring operated output drive is used. For example, in aerosol therapy for small pressure generating devices. For atomization Little of liquid medicine The locking mechanism for that output drive device is depressed with relatively little application of force. And will release with one hand The locking mechanism consists of an additional force transmission device, for example a threaded transmission device to press the spring, a locking element arranged in a ring with two leaning working surfaces to limit the Travel of spring and release button The device is compact Economical in production It is easy to assemble and assemble with low-wear components, the device can run sterile And easily accessible by the unskilled Even when there is spring force involved, so the drug to be measured Can be accurately made a mist
