Title:
PUMP DRIVING APPARATUS FOR MEDICAL CARE
Document Type and Number:
Japanese Patent JP3236324
Kind Code:
B2
Abstract:
PURPOSE: To provide a pump driving apparatus for medical care which can remove air bubbles in a liq. path consisting of a pump for medical care, an artificial lung, a tube, etc., in a short time without performing a complicated procedure.
CONSTITUTION: When a priming key 23 is turned on, a CPU 40 outputs a priming signal (a) to a motor driving circuit 50 to drive intermittently a motor 4. Ringer's soln. is intermittently transferred thereby by means of a centrifugal pump and air bubbles adhered to the inner wall face of a tube etc., is separated and removed by strength and weakness of energy of the flow of this Ringer's soln. The set value of electric voltage etc., for this intermittent driving can be changed by using a mode key 24, an up key 25 and a down key 26 and a dialogue mode between an operator and a message display part 27. In addition, when a start key 21 is turned on during the intermittent driving like this, a start signal (b) is output to a motor driving circuit 50 and driving of the motor 4 is switched thereby from intermittent driving to const. speed driving.
