PORTABLE APPARATUS FOR THE EMERGENCY ASSISTANCE OF A PATIENT SUFFERING FROM ACUTE RESPIRATORY FAILURE

摘要

The invention relates to a portable apparatus for emergency assistance, employed for the artificial respiration and general anaesthesia of a patient suffering from acute respiratory failure. According to the invention, the apparatus comprises an air pump (A) driven by a pumping mechanism (B) either mechanically with a direct current electric motor whose rotative speed is adjustable by means of an electronic variator, or manually by means of a detachable hand lever (2), a buffer chamber (C) for mixing the air with the oxygen or/and anaesthetic substances by an air absorption (G) by means of a piston which opens a drain path to the patient at the inspiration, upon exceeding the pressure determined by the attraction force of some magnets and some compression springs (18).
