Abstract: A device for separating tramp metals from liquid raw materials includes a body unit, a holding unit, a magnetic unit, a rinsing unit, and a driving unit. The body unit includes a tank for feeding-in and feeding-out liquid raw materials. The holding unit is coupled to the tank and includes and a plurality of non-magnetic holders received in the tank. The magnetic unit is mounted on the tank and includes an enclosure haying a telescopic wall to be in a compressed or extended state. The rinsing unit is fixed on the interior of the tank to rinse the non-magnetic holders. The driving unit is coupled the tank and the magnetic unit for driving the magnet unit moving between a first and second positions. An assembly is assembled from the device. And a method is carried out by the device or the assembly.

Abstract: A digitized hospital management system is provided with an in-hospital region including a first computer including a first interface and a plurality of first memory units; and a plurality of first video recording devices; an out-of-hospital region including a second computer including a second interface and a plurality of second memory units; a plurality of second video recording devices; and a plurality of auxiliary memory units; two communication devices disposed in the in-hospital region and the out-of-hospital region respectively so that the in-hospital region communicates with the out-of-hospital region or vice versa via the communication devices; and a hospital computer in data communication with the second computer.
