Pen 100 is not only simple in structure, and convenient for adjusting and using.
Some specific embodiments according to the present invention, limit knob 50 is movable along multiple gears in spacing collar 40,
The each gear for limiting knob 50 is corresponding with each unit of dose in bracket 10, and limits knob 50 in spacing collar 40
Total gear number it is equal with total units of dose in bracket 10.
Further, adjusting rod 30 is configured to be less than the regulation stall dose of adjusting rod 30 when the dose in bracket 10
When, adjusting rod 30 is only capable of the regulation stall of the residual drug in adjusting bracket 10.
Specifically, being somebody's turn to do the disposable injection pen 100 with dosage feedback device in regulating dosage, adjusting rod 30 is up
Rotation, limit knob 50 and then rotate, and spacing collar 40 does not rotate, and only and then rise, at this point, limit knob 50 is relative to limit
Sleeve 40 up moves.When injection, spacing collar 40 and limit knob 50 follow adjusting rod 30 to rotate synchronously, and transport down together
It is dynamic, there is no relative motion between spacing collar 40 and limit knob 50.Complete Primary regulation, after injection, 40 phase of spacing collar
A certain distance is risen for limit knob 50.The total kilometres for limiting knob 50 correspond to total units of medicine bottle Chinese medicine dose,
The drug of a unit dose is injected, limit knob 50 makes a move, and when drug injection is completed, limit knob 50 is just gone to
40 top of spacing collar.When the gear that surplus deficiency adjusting rod 30 is carved in medicine bottle, adjusting rod 30 be only adjustable be equivalent to it is surplus
The gear of remaining dose.When limit knob 50 rises to 40 top of spacing collar, adjusting rod 30 will not be able to rotate, and realize limit.
