Patient head limiting and fixing device for medical examination

Abstract

A patient head limiting and fixing device for medical examination comprises a head lying plate and a body lying plate, movable seats are arranged on the two sides of the upper end of the head lying plate correspondingly, arc-shaped blocks are arranged on the sides, close to each other, of the two movable seats correspondingly, and a width adjusting mechanism is arranged in the head lying plate and comprises a worm wheel; the lower side of the worm wheel is connected with a worm in a meshed mode, one end of the worm is fixedly connected with a connecting rod, and one end of the connecting rod is fixedly connected with a double-end screw rod. The invention has the following beneficial effects: the width adjusting mechanism is arranged, the double-end screw rod is driven to rotate through worm and worm wheel transmission of the width adjusting mechanism, and the sliding block can be driven to be relatively close to each other; the arc-shaped blocks are driven to be close to the two sides of the head of the child, the two sides of the head of the child are fixed between the two arc-shaped blocks, adjustment can be conveniently conducted according to the width of the head of the child, and even if the child shakes left and right, due to the self-locking performance of the worm gear and the worm, the worm cannot be driven by rotation of the worm gear to rotate, and the arc-shaped blocks cannot move and are quite stable.

Description
