摘要：
The invention relates to a portable ultrafiltration device comprising a bellows aspirator (9) connected by a pipe (8) passing through a solenoid valve (10) to one of the dialysate connectors of a hemofilter (1) integrated in a circuit. consisting of arterial lines (2) coming from a vascular access (4) and passing through a peristaltic pump (5) and venous lines (3) passing through an electronic safety block (6) and meeting the vascular access (4) while the other dialysate connector is connected to an ultrafiltration pressure detector (7). the peristaltic pump (5), safety electronic block (6), ultrafiltration pressure detector (7) and solenoid valve (10) are connected and controlled by an intelligent central unit (11) powered by a rechargeable battery. The patient's blood circulates in the blood circuit and the negative pressure generated by the suction bellows (9) is transmitted through the connection tubing (8) and causes the ultrafiltration of the blood through the hemofilter fibers (1). thus, liquid accumulates in the space around the fibers and in the suction bellows (9) until it is completely filled. As the suction bellows (9) is filled, the negative pressure exerted by it exhausts itself until it becomes null, then slowly increases until it reaches the level of the pressure in the blood contained in the fibers. At this moment the ultrafiltration stops and the central unit (11) indicates to the user the end of the treatment by a visual and audible alarm. blood is returned to the patient by infusion of an isotonic physiological solution. the hemofilter (1) and the suction bellows (9) are then removed from the device.a invenção diz respeito a um dispositivo portátil para ultrafiltração que comporta um fole aspirador (9) ligado por uma tubulação (8) que passa através de uma eletroválvula (10) a um dos conectores de dialisato de um hemofiltro (1) integrado em um circuito sanguíneo constituído por linhas arteriais (2) provenientes de um acesso vascular (4) e que pass
