FIELD: medical engineering.
SUBSTANCE: device has reservoir having tightly sealing cover, flexible membrane mounted on end surface of reservoir neck. Free conic membrane portion is turned inside into the reservoir and ends in a tube determining limit level in filling the reservoir. Bacterial filter manufactured from a sheet of hydrophobic porous material is mounted between the membrane and cover for gases to pass. The device has entrance for making connection to sucking catheter and exit for making connection to vacuum pump.
EFFECT: simplified design without reduction in filter passability; enabled liquid collection in reservoir of any type.
