Abstract

A device and system for delivering an aerosol to a patient on ventilatory support comprise a contact component 10 to be positioned in contact with a respiratory organ. The contact component 10 comprises a lumen 18 a, 20 a, 24 through which breathing gas and an aerosol are delivered to lungs of a patient.

First claim

The invention claimed is:

1. A device for connection of the airways of a child, infant, neonate or pre-term neonate patient on ventilatory support with a source of a breathing gas and a source of an aerosolized powder, said device comprising
a contact component adapted to be positioned in contact with the airways, the contact component comprising:
two first tubes each comprising a first lumen or lumens through which breathing gas and aerosolized powder can be delivered to the airways of the patient;
a second lumen which is in fluid connection with the first lumen or lumens of the two first tubes and having a longitudinal axis extending substantially perpendicularly to longitudinal axis or axes of the first lumen or lumens;
and
a second tube leading from the source of the aerosolized powder to a first port connected to the second lumen in the contact component through which the aerosolized powder can be introduced into said second lumen, and arranged such that the aerosolized powder and the breathing gas can be mixed in the second lumen;

the device being characterized by a third lumen being connected to a device for generating a flow of breathing gas, wherein the second lumen is positioned proximal to, and is in fluid connection with, said third lumen, through a second port wherein the first port is configured to introduce the aerosol into said second lumen essentially perpendicular to the longitudinal axis of the two first tubes or one of the two first tubes into said second lumen, and wherein the second port is configured to introduce the breathing gas into said second lumen essentially parallel to said longitudinal axis of the two first tubes or one of the two first tubes into said second lumen.

2. The device according to claim 1 , characterized in that the contact component is removably connected to a contact component holder which comprises the third lumen.

3. The device according to claim 2 , characterized in that the contact component comprises an inlet lumen adapted to receive a contact component holder lumen, wherein the inlet lumen is in fluid connection with the second lumen.

4. The device according to claim 1 , characterized in that the contact component is a nasal prong.

5. The device according to claim 1 , characterized in that the two first tubes are designed to be inserted into the patient's nostril or both nostrils, or the patient's nasal cavity.

6. The device according to claim 1 , characterized in that the connection of the third lumen to the device for generating a flow of breathing gas is via at least one third tube.

7. The device according to claim 1 , characterized in that the first port is configured to direct the aerosolized powder into said second lumen coaxially with or at an acute angle with respect to a longitudinal axis of the second lumen.

8. A combination of the contact component according to claim 1 , a contact component holder and optionally a means to secure the contact component to the contact component holder, characterized in that: the contact component comprises a lumen, the contact component holder comprises a lumen, and when the contact component holder holds the contact component, the lumens of the contact component and the contact component holder, respectively, are in fluid connection.

9. A system for administration of an aerosolized powder to a child, infant, neonate or pre-term neonate patient on ventilatory support, the system comprising a device for connection with the patient's airways according to claim 1 , a device for generating a flow of breathing gas, means for generating said aerosolized powder, wherein flows of breathing gas and aerosolized powder are introduced into said contact component.

10. The system according to claim 9 , comprising a holder and characterized in that said holder and said contact component are detachably connectable.

11. The system according to claim 10 , characterized in that the holder comprises a lumen in fluid connection with the second lumen of the contact component.

12. The system according to claim 10 , characterized in that the contact component comprises a flexible strap which is detachably connectable at said holder.

13. The system according to claim 9 , characterized in that the tubes can be inserted into the patient's nostril or both nostrils, or the patient's nasal cavity.
