Apparatus for administering intermittent percussive ventilation and breathing head assembly unit for use therein

摘要

Apparatus (11) for administering intermittent percussive ventilation to a patient having a respiratory tract comprising a device intrapulmonary percussive ventilation (16) to provide sources bajoun gases flow and a cyclic flow, and breathing head assembly (14 ), the assembly comprising an elongate cuerpoprincipal (26) having proximal and distal ends (27, 28) and having a flow passage (29) seextiende from the proximal end to the distal end, the main body (26) a port for víarespiratoria (61) adapted to be in communication with the airway of the patient and in communication withthe flow passage of the main body, an expiratory port (66) carried by the main body proximally delpuerto for airway, a valve seat (32) formed in the main body and circumscribing the deflujo passage (29) in the main body, an injector body (36) mounted slidably in the passage main delcuerpo flow and having proximal and distal (37, 38) having the injector body its distal end WHAT CAN move to engage and disengage the valve seat, the body of injector one tipoventuri passage (42 ) extending therethrough from a proximal end to a distal end, a diaphragm (51) carried by the coupled to the injector body main body, a nebulizer (13) having a delnebulizador container (126) that provides a chamber nebulization (132) therein, and deldispositivo tubular coupling intrapulmonary percussive ventilation to the nebulizer and the main body for supplying a sTREAM gas to nebulizer and a pulsatile flow of gas to the main body, wherein: the diaphragm (51 ) has a retractable memory for retaining the injector body in a retracted position conrespecto the valve seat, the main body (26) has an integral depending portion (81) forming a plenum chamber (82) encomunicación with the flow passage in the main body, a means of cooperative agreement (121) ensures removably the delnebulizador body dependent portion is provided main body and establish communication between the chamber and denebulización plenum dependent on the integral main body portion.
