drug delivery dosage, rotate the rotating cylinder anticlockwise to enable the first threaded sleeve to stretch out, observe the scale strip to be adjusted to the preset position, and the user can conveniently and rapidly deliver the
drug delivery dosage. The
liquid storage bag is filled with the medical
lubricant, the medical
lubricant is adhered to the outer wall of the injection tube through the
sponge ring, friction and discomfort during
insertion are reduced, and the acceptability and compliance of a patient are improved, especially under the condition that multiple times of administration are needed, through the design, the dosage of the
liquid storage bag is ensured to be accurate, and the liquid storage bag is filled with the medical
lubricant and is adhered to the outer wall of the injection tube through the
