Weinmann Geräte für Medizin GmbH + Co. KG (as Weinmann company is officially known) is planning to profile its line of ventilators at the upcoming annual convention of the German Society of Anesthesiologists and Intensive Care Medicine. The highlight of the event will be a presentation of the company’s new VENTIlogic ventilator, a device designed for at home respiratory support.
This new blower can be integrated into a larger system called “Ventilation Workstation”:
It features one of the most innovative home ventilation devices (VENTIlogic) developed by the company interacting with a monitoring unit, transcutaneous blood gas monitoring, an optional blood gas analysis and a suction pump for secretion removal. The most important ventilation and blood gas parameters are shown in curves and trend diagrams on a monitor. All the components will be presented on a special trolley for the system’s mobile temporary use, for example, during post-operative ventilation, in the intermediate care unit or in nursing homes or rehabilitation centers. "We would like to show users what a complete mobile system solution looks like and the benefits it offers," said Jörg Mielenz, product and ventilation specialist at Weinmann.
The innovative VENTIlogic is the first "intelligent" home mechanical ventilator whose patented TAV (Timed-Adaptive Ventilation) mode anticipates the patient’s respiratory pattern and thus significantly increases therapy compliance. Under controlled ventilation of patients with a weakened respiratory pump, "respirator fighting" can often be observed. The patient unconsciously begins to breathe against the rhythm of the ventilator, which puts a greater strain on the respiratory pump. This "fighting" is so unpleasant that the patient’s therapy compliance declines. "A potentially high unloading of the respiratory pump was often connected in the past with lower therapy compliance and consequently with low therapeutic effectiveness." Mielenz said. "Ventilators that are triggered by the patient’s spontaneous breathing and are therefore found to be more pleasant, however, relieve the respiratory muscles to a lesser extent and lead to hyperventilation of the patient." The innovative TA mode in VENTIlogic makes it possible for the first time to combine the high compliance of spontaneous ventilation modes with the high unloading (about 90%) of controlled ventilation modes.
When combined with the new oxygen valve VENTI-O2 plus, the VENTIlogic ventilation device can safely and reliably provide up to 15 liters of oxygen to the patient, for example, during the weaning phase. A change in the safety concept for VENTIlogic has made this possible. From now on the device fulfills the requirements of the current ISO EN 60601-1 norm for fire protection even as it applies to the delivery of large volumes of oxygen. For compliance purposes, the air-tightness of the air and oxygen conducting components in the device was improved, an optimized power unit was installed and new fire-resistant materials were used. The optimized "new" VENTIlogic will be available as of the middle of May.
The last statement is for the German audience. We are not aware that the device has been OK’ed by the FDA or by the Canadian authorities.
