摘要：
Disclosed is a single use pen like injector device (100) for delivery of follicle stimulating hormone (FSH) solution. The device (100) provides a single use and simpler self-administration of the FSH solution. A needle shield (120) is also provided to prevent needle or injection anxiety of the user. The device (100) comprises an elongated main housing (110)； an elongated rotator (118)； a knob (160)； a plunger rod (116)； a permanently encased needle assembly； a cartridge holder (150)； a needle shield (120) and a removable cap. The main housing (110) includes distal and proximal portions arranged along a longitudinal axis. The elongated rotator (118) is connected to the proximal portion of the main housing (110) and is rotatable along the longitudinal axis with respect to the main housing (110). The knob (160) extends from the proximal portion of the main housing (110) and is rotatable between a lock position and seven or fewer discrete dosing positions for setting variable dose delivery of FSH solution. The knob (160) includes longitudinally spaced elements which correspond to the lock position and the seven or fewer dosing positions. The plunger rod (116) is rotatably engaged with a portion of the rotator (118) and it is longitudinally spring biased (115). The plunger rod (116) is rotatably locked to the knob (160) in the locked position and is incrementally movable along the longitudinal axis between the element corresponding to the lock position and of the elements of the seven or fewer dosing positions. The permanently encased needle assembly has a permanently attached needle. The needle includes an internal end and a working end. The cartridge holder (150) is proximately attached to the needle assembly and holds an elongated drug cartridge with FSH solution. The drug cartridge has a penetrable membrane adjacent to the internal end of the needle. A movable plunger is adjacent to the plunger rod (116). The drug cartridge is fluidly disconnected from the internal e
