Detailed ways

The preferred embodiments of the present utility model are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present utility model, and are not intended to limit the present utility model.

As shown in Figures 1 and 5, an insulin injector of the present invention includes a penholder 4, a dose adjustment button 6 is provided at one end of the penholder 4, and the dose adjustment button 6 is connected to a dose display window 5 arranged inside the penholder 4; One side of the dose adjustment button 6 is provided with an injection push key 7; one side of the dose display window 5 is fixedly provided with a dose indicator rod 8; one side of the penholder 4 is provided with a piston rod 42, and the piston rod 42 and the dose adjustment button 6 pass The piston spring 41 is connected; one side of the pen holder 4 is threadedly connected to the refill holder 9 and the inside of the refill holder 9 is installed with a refill 10; One end of the refill 10 is fixed to the rubber piston 3, and the rubber piston 3 is connected to the piston rod 42;

In order to make the insulin syringe more convenient to use and the dose scale more accurate, it also includes a needle inner needle cap 101, a needle outer needle cap 102 and a needle protection sheet 103, the needle 1 is located inside the needle inner needle cap 101, and the needle 1 and the needle outer The needle cap 102 is connected by a buckle, and one end of the needle 1 is closed by a needle protection sheet 103; the needle 1 is a needle 1 provided with an internal thread, and the needle 1 is connected with the cartridge holder 9; the cartridge Frame 9 is a pen core frame 9 with a toothed side wall; the scale window 2 is a scale window 2 of a convex lens structure, and the scale window 2 is closely connected with the pen core frame 9; the diameter of the piston rod 42 is less than The diameter of the scale window 2, and the piston rod 42 is a cylindrical piston rod 42; the dose display window 5 is a dose display window 4 with a convex lens structure, which reduces production costs and is easier to operate.

When the utility model is in use, take off the pen cap 11, unscrew the pen core holder 9, push back the piston rod 42 to be on the same vertical plane as the pen holder 4, slowly put the end of the pen core without the rubber piston 3 into the pen core holder 9, Screw on the refill holder 9, gently rotate the dosage adjustment button 6 until you feel a little force, stop the rotation, remove the needle protection sheet 103 from the needle 1, screw the needle 1 on the end of the refill holder 9, and remove the outer needle of the needle Cap 102 and the inner needle cap 101 of the needle head, make one end of the needle head 1 vertically upward, gently tap the refill 10, so that the air bubbles inside the refill 10 gather at the needle head 1, adjust the dose adjustment button 6 so that the dose display window 5 is at two At the unit, press the injection push button 7.
