Overview / Highlights
- Low noise level
- Pressure trigger and spontaneous breath detection without additional sensor
- Flexible adapter for positioning prong and mask
- Patented flextubes for easy application
- Based on the Benveniste valve with volume reservoir
Quiet and comfortable
Medijet actively generates CPAP pressure using a modified Benveniste valve (Benveniste 1976), that is, directly in the generator, and thus the continuous positive pressure in the patients airway without an additional valve in the NIV device. As a result, Medijet is connected to the device with only a single-tube system. This facilitates handling and patient positioning.
Pressure trigger without additional sensor
Based on the precise and fast pressure measurement, Medijet enables the innovative pressure trigger MediTRIG. The spontaneous breathing and obstructive as well as central apnea are recorded without an additional sensor, such as an abdominal sensor.
In the medin devices, the pressure trigger is used in the Apnea CPAP and SNIPPV mode and thus opens up a broad range of types of non-invasive respiratory support
Medijet is secured to the patients head with the user-friendly medin bonnet. Medijet is applied to the nose of the small patient using short binasal prongs or soft, gentle nasal masks.

(E) Expiration open
The breathing gas flow set flows via the Benveniste valve into the pressure chamber of the Medijet (red). Pressure builds up there and supports the patient with pressure and flow. During inspiration, the pressure in the patients airway decreases, as does the resistance. The breathing gas always flows in the direction of low resistance.
The amount of breathing gas which is not needed by the patient may escape via the expiration opening (red, narrow). The airway pressure is measured directly in the Medijet via the proximal pressure measurement and transmitted to the therapy device.
During expiration, the expiratory flow (blue) from the patient meets the incoming fresh gas flow (red). This is redirected out to the environment in whole or in parts. The patient can exhale via the expiration opening and this results in a gas mixture consisting of expiration flow and fresh gas flow.
During expiration, PEEP is generated when the expiratory flow coincides with the device flow
