A manually operated respiration apparatus (1), comprising a respiration housing (2), provided with a respiration channel (4) for connection with a patient to whom artificial respiration is to be applied, which respiration channel (4) is connected via a valve system (5) with an inflow port (6) connected to a balloon unit (3) for supplying air to the patient via the respiration channel (4) and with an outflow port (7) for evacuation of air exhaled by the patient into the respiration channel (4) to the environnient, wherein the balloon unit (3) comprises a resilient bellows (10) provided with an inlet opening (8) and an outlet opening (9), wherein, further, in the inlet opening (8) of the bellows (10), a non-return valve (11) is included and wherein the outlet opening (9) of the bellows (10) is connected with the inflow port (6) of the respiration housing (2). Upon squeezing the bellows (10), from a starting position, air enclosed by the bellows (10) exits via the outlet opening (9) and, upon releasing the bellows (10), it rebounds to the starting position by sucking in environmental air via the inlet opening (8). The bellows (10) is provided with. ® KIPO & WIPO 2007 |
