Abstract
The utility model provides an automatic pen-type insulin syringe with a dose memory function. The dose memory function comprises a pen body, a dose adjusting knob, a locating sleeve and a locating tooth ring. When dose is set for the first time, a braking key is pulled backward to enable a transmission nut to be locked, the dose adjusting knob is rotated to confirm a set value, and energy is stored by a torsion spring at the time. The locating sleeve is rotated so that a first locating blocking block of the locating sleeve is connected with a first limiting protrusion at the rear end of the pen body, and then the locating tooth ring is adjusted so that a second limiting protrusion of the locating tooth ring is connected with the front side of a second locating blocking block of the dose adjusting knob rotating clockwise. An angle between the first locating blocking block of the locating sleeve and the second limiting protrusion of the locating tooth ring is confirmed through meshing of teeth. Therefore, the dose can be accurately set for the second time or many times due to the fact that the dose adjusting knob is rotated clockwise to a locating point. The syringe has the advantages of being capable of memorizing the dose, automatically injecting, selecting the dose within 60 units, and being convenient to use for patients.
