Zusammenfassung: | The utility model provides a filling system which comprises a medicine liquid tank, a one-way stop valve I, a one-way stop valve II, a glass filling pump and a filling needle, wherein the medicine liquid tank is communicated with the lower end of the one-way stop valve I through a silicone tube; the upper end of the one-way stop valve I is communicated with the lower end of the glass filling pump through the silicone tube; the upper end of the glass filling pump is communicated with the lower end of the one-way stop valve II through the silicone tube; and the upper end of the one-way stop valve II is communicated with the filling needle through the silicone tube. The filling system has the beneficial effects that a white core piston is replaced by the one-way stop valve (blue core piston), so that the precision of the medicine liquid filling amount is completely controlled to be within the range less than or equal to 2%. |
