Abstract

The invention relates to a disposable insulin injection pen with adjustable dosage and convenient use and carrying, which comprises a pen cap, a needle head, an injection pipe internally provided with a piston and filled with drugs in advance, an injection sleeve, a positioning block, a screw, a nut pipe, a fixing pipe, a coil pipe, a clutch pipe, a scale positioning device and a button, wherein 0-60 scales which can be observed by a window of the fixing pipe are marked on the coil pipe, a clutch is formed by a face tooth of the clutch pipe and a tooth socket of the coil pipe so as to ensure the dosage is repeatedly adjusted to the accurate position before use, the clutch is switched on by pressing the button, the coil pipe drives the clutch pipe and the nut pipe to rotate by the interaction of a spiral bar of the fixing pipe and a spiral groove of the coil pipe, and thereby ensuring that the screw is pushed forwards to extrude the drugs in the injection pipe out. The screw can not be pushed backwards after use, which avoids repeated use. The invention integrates insulin with the injection pen, and can be discarded after use because a patient can not replace the injection pipe.
