ABSTRACT:
The flow rate regulation, notably of a rapid perfusion flow rate, is effected by regulating the pressure in the perfusion reservoir by the application of a voltage to a compressor, which increases the flow rate of the liquid in the perfusion tubing by sending pressurized air into the reservoir. The latter is at atmospheric pressure when no voltage is applied to the compressor. The device comprises the combination of a perfusion reservoir and a compressor which causes the pressure in said reservoir to vary. Consequently the flow rate of the perfusion liquid delivered by the latter into the perfusion tubing varies. The compressor is governed by a differential voltage resulting from the comparison by an electronic circuit of the real value with the desired value of the flow rate in the perfusion tubing. This differential voltage is applied to the compressor which then sends compressed air into the perfusion reservoir.
