FIELD: medical engineering. SUBSTANCE: device has patient arterial blood pressure pulsations simulator designed as cylinder manufactured from flexible material, compression cuff of measurement device under control, working reference pressure source, pressure pulsation frequency setter, simulating pulse frequency, control unit and means imitating patient artery designed as flexible tube rigidly coupled to the cylinder and connected to an additional cylinder manufactured from flexible material. Compression cuff is put over the tube and cylinder. Pulsation setter has quartz frequency oscillator and electromagnet which rod is tightly engaged with additional cylinder bottom part. The tube and cylinder are filled with liquid. The tube is connected with its free end to chamber for extinguishing pulsations filled with liquid. EFFECT: wider variety of measurement devices under control. 3 cl, 1 dwg |
