Detailed description of the invention
Below in conjunction with accompanying drawing, principles of the invention and feature being described, example is served only for explaining the present invention, is not intended to limit the scope of the present invention.
As shown in figs. 1-7, a kind of multi-cavity type syringe, being made up of gland 1, piston rod 2, piston 3, upper cavity 7, lower chamber 11, syringe adapter 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, being provided with rotating shaft set 4 in described upper cavity 7, described rotating shaft set 4 is positioned at the center of upper cavity 7, and the inner surface of described rotating shaft set 4 is provided with box 5；
The fixed installation rotating shaft 8 of described lower chamber 11 upper surface side, 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 diaphragm seal 101, 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, diaphragm seal 101, 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, the vertical side walls of the two of described groove 18 is barrier film 14；The comprcssive strength of described barrier film 14 respectively diaphragm seal 101, diaphragm seal 102 1/100；
