ASPIRATOR FOR ASPIRATING VENOM OR POISON SUBSEQUENT TO A BITE OR STING

摘要

An aspirator for aspirating venom or poison from a bite or sting. The aspirator includes an elongated housing defined by a circumferential wall delimiting a suction chamber, with the housing having a suction end with a suction opening and the circumferential wall having at least one slot extending axially from the opposite end; a piston member with a piston head connected to a piston rod which is movable between a fully depressed position and a fully retracted position inside the housing; a grip protruding through the at least one slot of the housing for moving the piston member axially inside the housing to adjust aspiration pressure; and an end closure for closing the opposite end of the housing to confine the piston member inside the housing. The suction end of the elongated housing is partly closed by an annular end wall inclining inside the housing and encircling the suction opening.
