The 700 Series Ventilator System is used to provide continuous ventilation to patients requiring respiratory support. This device is used for a wide range of patients from pediatric to adult and for a wide variety of clinical conditions. It also has the capability to provide nebulization through use of an optional accessory, the EasyNeb Nebulizer.

The device is a low-cost, critical care ventilator intended to provide continuous ventilation for pediatric and adult patients, with the provision of nebulization functionality, through use of an optional accessory, the EasyNeb Nebulizer. The nebulization functionality is implemented by: a) modifying the 700 Series software to activate a nebulizer interface which directly controls the power and operation of the EasyNeb Nebulizer and b) the provision of an external nebulizer, the EasyNeb Nebulizer, as an optional accessory. which is intended to be used solely with the 740 and 760 ventilators. The modification to the ventilator is the activation through software of the nebulizer port on an existing Communications interface option. This nebulizer port facilitates electrical connection of the EasyNeb Nebulizer to the ventilator, the operation of which is controlled completely by ventilator software. The ventilator modification in essence then is a software modification which allows control of the nebulizer power on/off, the nebulization period and mode of operation. The EasyNeb Nebulizer is an ultrasonic nebulizer which is designed to deliver aerosol medications to the patient without affecting ventilator performance or patient data. It is powered and controlled by a 700 Series Ventilator, with the Communications Option installed. It contains a piezoelectric crystal that generates ultrasonic waves. The crystal's vibrations are transmitted through buffer water to a medication cup and convert the liquid medication into fine particles. The nebulizer medication cup is designed for single-patient use only, and holds up to 10 mL of medication.
