The invention relates to an applicator for a nasal cannula, comprising a body (11) enclosing a hollow space (22). The applicator further comprises tube connections (20, 21) for supplying a respirable gas into the hollow space (22). The applicator further comprises prongs (18, 19) for administering the respirable gas into the nostrils of a person. A valve (15, 16, 17, 38, 42) is located in a wall of the body (11) so that respirable gas can flow from the outside through the valve into the hollow space (22), but not in the reverse direction. The invention further relates to an applicator having a top of sealing cones (23, 24), wherein the sealing cones (23, 24) may be provided with rim-shaped sealing lips on their side facing away from the body (11), which produce a tight seal with the inner wall of the respective nostril.

1. An applicator for a nasal cannula, comprising: a body enclosing a hollow space;a first tube connection and a second tube connection for supplying a respirable gas into the hollow space, the first tube connection and the second tube connection being integrally formed on the body;a first prong and a second prong for administering the respirable gas into the nostrils of a user, the first prong and the second prong being integrally formed on the body;a valve in a wall of the body, the valve being constructed such that the respirable gas, independent of the respirable gas supplied via the first tube connection and the second tube connection, can flow directly from an outside of the body through the valve into the hollow space and then further to the first prong and the second prong, wherein the valve inhibits gas flow from the hollow space through the valve to the outside of the body; anda top that is slipped over the first prong and the second prong for sealing between the first prong and the second prong and an inner wall of a respective nostril, said top being formed of a first sealing cone and a second sealing cone, wherein the first sealing cone and the second sealing cone have on a side facing away from the body a different cross-section area and a different cross-section shape than on a side facing the body, said first sealing cone and said second sealing cone being mechanically connected by a bridge on the side facing the body. 2. Applicator of claim 1, wherein the two sealing cones have one or more rim-shaped sealing lips on the side facing away from the body, which produces a tight seal with an inner wall of a respective nostril. 3. An applicator for a nasal cannula, comprising: a body enclosing a hollow space;a first tube connection and a second tube connection for supplying a respirable gas into the hollow space, wherein the first tube connection and second tube connection are integrally formed on the body;a pair of prongs comprising a first prong and a second prong for administering the respirable gas into nostrils of a user, wherein the first prong and the second prong are integrally formed on the body; anda top slipped over the pair of prongs for sealing between the pair of prongs and an inner wall of a respective nostril, wherein the top is formed of sealing cones comprising a first sealing cone and a second sealing cone, wherein the sealing cones have on a side facing away from the body a different cross-section area and a different cross-section shape than on a side facing the body; wherein the sealing cones have one or more rim-shaped sealing lips on a side facing away from the body that produces a tight seal with the inner wall of the respective nostril, wherein each of the two sealing cones further comprises an inner part, an outer cone and ribs, wherein an inner circumferential surface of the inner part forms a fit with an outer circumferential surface of a respective prong, and wherein the ribs mechanically connect the inner part to their respective outer cone to allow a gas flow parallel to the inner part between the inner part and their respective outer cone. 4. An applicator for a nasal cannula, comprising: a body enclosing a hollow space;a first tube connection and a second tube connection for supplying a respirable gas into the hollow space, the first tube connection and the second tube connection being integrally formed on the body;a first prong and a second prong for administering the respirable gas into nostrils of a person, wherein the first and second prongs are integrally formed on the body; anda top slipped over the prongs for sealing between the prongs and an inner wall of the respective nostril, wherein the top is formed of a sealing cones, namely a first sealing cone and a second sealing cone, wherein the sealing cones have on a side facing away from the body a different cross-section area and a different cross-section shape than on a side facing the body, wherein each of the two sealing cones further comprise an inner part, an outer cone, and ribs, wherein an inner circumferential surface of the inner part forms a fit with an outer circumferential surface of its respective prong and wherein the ribs mechanically connect the inner part to the respective outer cone to allow a gas flow parallel to the inner part between the inner part and the respective outer cone. 5. The applicator of claim 4, wherein the inner part projects on a body-sided end over an outer cone body-sided end in the direction of the body, the inner part being provided with a circumferential step at the outer cone body-sided end, wherein the circumferential step presses a shim-shaped membrane against the outer cone body-sided end, wherein the shim-shaped membrane seals the opening between the inner part and the outer cone. 6. The applicator according to claim 5, wherein the prongs further comprise a collar on their nose-sided end, wherein an outer diameter of the collar is larger than central openings within the inner part of each of the two sealing cones. 7. An applicator for a nasal cannula, comprising: a body enclosing a hollow space;a first tube connection and a second tube connection for supplying a respirable gas into the hollow space, wherein the first tube connection and second tube connection are integrally formed on the body;prongs comprising a first prong and a second prong for administering the respirable gas into the nostrils of a user, wherein the first prong and the second prong are integrally formed on the body, wherein the prongs further comprise a collar on a nose-sided end of the prongs; anda top slipped over the prongs for sealing between the prongs and an inner wall of a respective nostril, wherein an outer diameter of the collar is larger than nose-sided ends of central openings formed within an inner part of two sealing cones, said top being slipped over the prongs such that the nose-sided ends of the central openings of the two sealing cones are placed below a body-sided end of the collar. 8. The applicator according to claim 7, wherein the body further comprises a hole embedding a cover, wherein the cover has a groove, wherein an edge of the hole of the body engages into the groove, wherein the cover has an aperture sealed by a flexible membrane on a side facing the hollow space to allow a gas flow from an ambiance through the aperture in the cover into the hollow space, wherein the flexible membrane prevents gas flow from the hollow space through the aperture in the cover into the ambiance. 9. The applicator according to claim 7, wherein each said collar is located at a position above said nose-sided end of one of said central openings. 10. The applicator according to claim 7, wherein each of said two sealing cones comprises an end portion, each said collar being located at a position above said end portion of one of said two sealing cones. 11. The applicator according to claim 7, wherein nose-sided ends of said sealing cones are positioned below said collar. 12. The applicator according to claim 7, wherein each of said two sealing cones comprises a nose-sided end, said nose-sided end of each of said two sealing cones being located at a position below said collar of one of said prongs.
