Nebulizer

摘要

A nebulizer comprises a head detachably coupled to a body. The head comprises the nebulizer, an air channel and a flow sensor. A nebulized liquid is released in an air channel that ends in a mouth piece through which a user inhales and exhales. The inhaling and exhaling causes a flow in the air channel which is detected with the flow sensor. The nebulizer is controlled by controls and sensors included in the body.

1. A nebulizer comprising;
a head, the head comprising;
a medication chamber configured to hold medicament as a body of liquid,a vibration source configured to apply vibrational energy to a medicament within the medication chamber in order to nebulize the medicament, such vibrational energy being applied to the medicament while the medicament is held as a body of liquid in the medication chamber,an air channel in which the nebulized medicament is released, the air channel being arranged to guide a flow caused primarily by respiratory effort of a user during an inhaled and exhaled breath of the user; anda sensor configured to generate output signals that convey information related to a direction of the flow; and a body detachably coupled to the head, the body comprising a controller to control operation of the vibration source between different non-zero frequencies for different directions of the flow.
