Taking FIG. 3 as an example, the thickness of the left inner wall of the hollow neck portion 122 is smaller than the thickness of the right inner wall. In contrast, the thickness of the right inner wall of the hollow base portion 124 is smaller than the thickness of the left inner wall.

The inner wall thickness design of the hollow base portion 124 can also guide the deformation of the needle-filled elastomer 12 . As shown in FIG. 4, when the syringe mouth portion S presses the top portion 120 of the needle-filling elastic body 12, the left inner wall of the hollow neck portion 122 is more easily deformed than the right inner wall, so that the left side of the top portion 120 is inclined downward. The right inner wall of the hollow base portion 124 is more easily deformed than the left inner wall, so that the left side of the top portion 120 is further inclined downward, and the left side of the needle-loading elastic body 12 is away from the inner wall of the outer cover 10 to form an accommodation. The space of the liquid medicine. The liquid in this space can then flow into the drip line via the drug perforation 140 on the susceptor 14. In other words, when the needle dispensing system 1 is pressed by the needle mouth S, the dosing channel is regularly and stably supplied to the metering cylinder or the drip line.

Further, the hollow base portion 124 is formed with a circular arc structure 1240, so that the hardness of the hollow base portion 124 can be appropriately reduced, and the hollow base portion 124 can be easily deformed as a whole when the cylinder is pressed, as shown in FIG. On the other hand, the circular arc structure 1240 can further provide a spring-like effect, that is, when the syringe presses the top 120, the circular arc structure 1240 produces a deformation as shown in FIG. 4 while providing an upward elastic restoring force. When the mouth of the syringe stops applying force, the aforementioned elastic restoring force can help the needle-filling elastic body 12 to quickly return to the original shape to close the medicine receiving port 100. On the other hand, the circular arc structure 1240 correspondingly enlarges the bottom area of the needle-filling elastic body 12, so that the needle-filling elastic body 12 can be more stably abutted against the base 14 when it is deformed by compression.

Based on the structure of the above-described needle-adding elastic body 12, it can be regularly and stably deformed when it is pressed by the needle mouth portion S, and can also stably abut against the base 14 without shaking. In contrast, when the needle mouth S stops applying force, the needle-filling elastic body 12 can smoothly return to the original position in the original deformation direction.
