DEVICE FOR PRODUCING MAGNETIC NEGATIVES Russian patent published in 1998 - IPC

FIELD: medical engineering. SUBSTANCE: device has magnetic field source as electric magnetic coil which winding envelope its carcass and magnetic conductor, two pairs of polar plates having N and S polarity in operation mode, fencing for molding material, base, two modeling devices. Two pairs of polar plates are pivotally connected to each other and a core and are set in horizontal position. Notch is produced in the upper polar plates for anatomical object to pass through and holes for filling the molding material in. The core is set in vertical position and provided with rest member for mounting on base. Ring-shaped grooves are produced on flat hinge surface of the inferior polar plates. The core is composite. It has cylinder playing the role of an axle and bushing enveloping the cylinder. Flat end face surfaces of the core are engageable with the flat hinge surfaces of one of a pair of polar plates. Its cylindrical surfaces are engageable with the responding cylindrical surfaces of the holes in the other pair of polar plates (basic one). Core bushing end faces are engageable with internal surface of one from a pair of polar plates. Locking member for fixing electric coil position can be mounted on the device base. Modeling device has plate with slots and nut attached to it for lead screw to be placed. The screw has handle on its one side and pin for mounting modeling nozzle on its other side. Semi-circular ferromagnetic inserts are positioned in the notches of the upper polar plates. The device has adjustable support unit for anatomical object to be placed there and clamp for joining the halves of the device. EFFECT: wide range of functional applications; reduced material and power costs; small size in length. 10 cl, 3 dwg
