Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining this utility model, is not intended to limit scope of the present utility model.
As shown in figs. 1-7, a kind of multi-cavity type syringe, be made up of gland 1, piston rod 2, piston 3, upper cavity 7, lower chamber 11, syringe joint 15 and syringe needle 12, described gland 1 is connected with the head end integrated injection molding of piston rod 2, and described piston 3 is connected with the tail end of piston rod 2;
Described upper cavity 7 is provided with plunger shaft 16, the maximum outside diameter of described piston 3 is directly consistent with the minimum inner circle of plunger shaft 16, be provided with rotating shaft cover 4 in described upper cavity 7, described rotating shaft cover 4 is positioned at the center of upper cavity 7, and the inner surface of described rotating shaft cover 4 is provided with box 5;
Described lower chamber 11 upper surface side fixed installation rotating shaft 8, the outer surface of described rotating shaft 8 is provided with pin thread 9, the upper and lower surface of described lower chamber 11 is respectively equipped with the first diaphragm seal 101, second diaphragm seal 102, described lower chamber 11 is provided with partition 6, described partition 6 number is four, described lower chamber 11 is provided with medicinal liquid cavity 17, described medicinal liquid cavity 17 is by partition 6, first diaphragm seal 101, second diaphragm seal 102, lower chamber 11 surrounds, described plunger shaft 16 is corresponding consistent with medicinal liquid cavity 17 size, the lower surface center of described lower chamber 11 is provided with groove 18, two vertical side walls of described groove 18 are barrier film 14, the comprcssive strength of described barrier film 14 is respectively 1/100 of the first diaphragm seal 101, second diaphragm seal 102,
The maximum inscribed circle diameter of described rotating shaft cover 4 is greater than the minimum outside diameter of rotating shaft 8 and the minimum interior circular diameter of described rotating shaft cover 4 is less than the maximum outside diameter of rotating shaft 8;
