The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

see also Fig. 1 and Fig. 2, this utility model syringe comprises overcoat 1, core bar 3, entry needle 2 and needle tube protecting sleeve 4, core bar 3 is located in overcoat 1, entry needle 2 is located at the front end of overcoat 1, needle tube protecting sleeve 4 is located at the outside of entry needle 2, core bar 3 comprises thin front bar 31 and thick rear bar 32, and the excircle of core bar 3 front ends is provided with annular groove, annular groove is embedded with annular rubber cushion 5, the profile of the profile of overcoat 1 and core bar 3 is complementary, pipe 11 and thick rear pipe 12 before comprising carefully, before overcoat 1 is thin, the excircle of pipe 11 is provided with take 0.005 milliliter or 0.0025 milliliter as unit and maximum scale is the graduation mark 13 of 0.05 milliliter, the diameter of core bar 3 thin front bars 31 is 1.6 millimeters, the diameter of thick rear bar 32 is 4.5 millimeters.

The thin front pipe 11 of overcoat 1 is because diameter is less, can carry out low dose of injection, coordinate again simultaneously thin before on pipe 11 excircles take 0.005 milliliter or 0.0025 milliliter as unit, maximum scale is the graduation mark 13 of 0.05 milliliter, make this utility model syringe can carry out accurate dose injection, can thoroughly satisfy infant or neonate when injection for the requirement of injection precision.

Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that do not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
