OPENABLE HELMET OF NON-INVASIVE VENTILATION OF PATIENTS

摘要

A helmet (10) for non-invasive ventilation of patients comprising:
a container body (20) in which there can be housed the head of a patient, provided with at least one optically transparent portion and with an open end to which a first rigid ring (21) is fixed;an elastically yieldable collar (30) which can be sealingly coupled to the neck of the patient and fixed to a second rigid ring (31) can be sealingly removably associated to said first rigid ring (21),

whose distinguishing characteristic consists in comprising a bayonet-like coupling means adapted to removably couple the first and the second rigid ring with respect to each other (21,31).

1. Helmet (10) for non-invasive ventilation of patients comprising:
a container body (20) in which there can be housed the head of a patient, provided with at least one optically transparent portion, an inlet pipe (22) for introducing air, an outlet pipe (23) for releasing air and an open end to which a first rigid ring (21) is fixed; an elastically yieldable collar (30) which can be sealingly coupled to the neck of the patient and fixed to a second rigid ring (31) which can be sealingly removably associated to said first rigid ring (21), an inlet pipe (22) for introducing a breathable gas into the inner volume enclosed by said container body (20) and said collar (30), and a gas outlet pipe (23) for releasing exhaled gases from said inner volume,characterised in that it comprises bayonet-like coupling means adapted to removably couple the first and the second rigid ring with respect to each other (21,31).
