The second reset structure 244 is spread to push the pushing structure 23 towards the direction away from the transmission rod 22, so that the pushing structure 23 is clung to the insulin refill 4, at this time, the pushing structure 23 returns to the position before the vibration work starts, at this time, the fixing pin 241 faces the groove on the side wall of the transmission rod 22, the electromagnetic valve 243 is opened, and the fixing pin 241 is attracted to be inserted into the groove on the side wall of the transmission rod 22.
In some embodiments of the present application, the clutch support 245 is rotatably connected to the pushing structure 23, and the clutch support 245 rotates along with the driving rod 22 driven by the injection motor 21 to drive the pushing structure 23 to move along a straight line, so as to squeeze the insulin pen core 4.
As shown in fig. 1 to 8, the insulin pen core 4 includes a reservoir 41 and a piston 42; the piston 42 is slidingly connected with the storage compartment 41; the interior of the reservoir 41 is adapted to the pushing structure 23 and the exterior is adapted to the drug reservoir 17.
Specifically, the outer wall of the storage compartment 41 is provided with a bump; one end of the pressing structure 5 is connected with the bump, and the other end is connected with the inner side wall of the insulin pen main body.
The process of shaking up insulin:
1. when the start key 36 is pressed, the electromagnetic valve 243 is firstly powered off, the first reset structure 242 pulls the fixing pin 241 out of the groove on the side wall of the transmission rod 22, so that the connection between the transmission rod 22 and the pushing structure 23 is disconnected, and then the shaking motor 32 begins to work again;
2. the shaking motor 32 drives the conduction unit 35 and the insulin pen core 4 to rotate through the transmission unit, and at the moment, the sliding block 353 moves in the slideway 16 to drive the conduction unit 35 and the insulin pen core 4 to do linear reciprocating motion while rotating;
3. after the shaking-up operation is finished, the pressing structure 5 resets the insulin pen core 4, and the second resetting structure 244 drives the pushing structure 23 to reset, so that the fixing pin 241 is opposite to the groove on the side wall of the transmission rod 22, the electromagnetic valve 243 is opened, and the fixing pin 241 is attracted to be inserted into the groove on the side wall of the transmission rod 22.
The process of insulin injection of the invention:
1. opening the protective cap 11 to expose the injection needle 15;
2. the adjusting knob 261 is rotated according to the reading of the display 27, so that the injection quantity is accurately adjusted;
3. the needle tip is inserted into the skin and the injection key 262 is pressed.
The process of changing the insulin pen core 4 comprises the following steps:
1. removing the limit bolts 131, and disassembling the front end shell 12 and the rear end shell 13 to expose the medicine bin 17;
2. taking out the used insulin pen core 4;
3. rotating the transmission rod 22 in the opposite direction to retract the pushing structure 23;
4. the new insulin pen core 4 is put into a medicine bin 17 and then into a compacting structure 5;
5. the front end housing 12 and the rear end housing 13 are assembled again.
The process of replacing the injection needle 15 of the present invention:
1. removing the protective cap 11 and the limit sleeve;
2. the injection needle 15 is taken out;
3. a new injection needle 15 is put into the front end housing 12 and penetrates into the interior of the insulin pen core 4;
4. a stop collar and a protective cap 11 are sequentially arranged.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are only preferred embodiments of the present invention, and are not intended to limit the invention, and that various changes and modifications may be made therein without departing from the spirit and scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
