Disclosed is an electromagnetic magnet with manual control and state detecting functions. A coil frame is mounted in a cover shell; the coil frame is wound by a coil; a "T"-shaped iron core is assembled at the upper end of the cover shell while a "T"-shaped cover plate is assembled at the lower end of the cover shell; the lower end of the "T"-shaped iron core extends into the coil frame; a base is fixed at the top end; a through hole with a conical opening in the lower end is formed in the center of the "T"-shaped iron core; a static spring sheet, a movable spring sheet and a state detection spring sheet are riveted on the base; an inverted "T"-shaped dustproof cover is assembled on the base; an armature is inserted in the coil frame; the upper part of the armature adopts a conical rod shape, and the conical shape part is adapted with the conical opening while the rod-shaped part is inserted in the through hole and passes through the base to extend to the upward side of the base; a reset spring is assembled on the rod-shaped lower part while a threaded rod is fixed on the upper part; the threaded rod is equipped with a butterfly nut; the lower end of the armature is adapted in a slot hole of the cover plate; a socket is mounted on the inverted "T"-shaped dustproof cover; and the socket is electrically connected with the state detection spring sheet and the coil separately. The electromagnetic magnet has the state detection function and reliability in long-term electrified operation; and meanwhile, the electromagnetic magnet can be manually controlled in power outage to realize function switching.

The invention discloses a disposable lumbar cistern drainage and multidirectional shunting device, comprising a four-way shunt device. The four-way shunt device comprises a three-way valve and an adjusting knob. The disposable lumbar cistern drainage and multidirectional shunting device is characterized in that the four-way shunt device is connected with a sample collection channel, an intrathecal injection channel, a cerebrospinal fluid collection channel and a fluid incoming channel; the intrathecal injection channel is provided with a seal rubber gasket fluid inlet; the fluid incoming channel is connected with a lumbar cistern drainage channel; the tail end of the sample collection channel is provided with a positive pressure valve; a spring is compressed on the positive pressure valve; a one-way valve is compressed to the other end of the spring through a one-way valve support cross-beam; the cerebrospinal fluid collection channel is connected with a cerebrospinal fluid collector. The disposable lumbar cistern drainage and multidirectional shunting device is capable of isolating germs, avoiding iatrogenic contaminations and preventing cerebrospinal fluid sample contamination, thereby improving accuracy of sample inspection; is convenient to operate; and has the functions of cerebrospinal fluid collecting, cerebrospinal fluid sampling and intrathecal injection.
