The utility model discloses a kind of sampling devices for
diclofenac sodium sustained-release
suppository detection, including sampling cylinder, the bottom of the sampling cylinder is communicated with sampling needle, the inside of the sampling cylinder is slidably connected with
piston, the top of the
piston is fixedly installed with pull rod, the top of the pull rod is fixedly installed with
handle, the utility model is rotated by rotating sleeve, so that two traction plates move to two sides respectively, square bar and clamping plate are moved by traction plate movement, after clamping plate moves and no longer contacts sampling cylinder, support plate can be slid on the surface of sampling cylinder, after sliding to appropriate position, by rotating rotating sleeve, so that
abutment rod no longer contacts traction plate, clamping plate can be reset and clamp the surface of sampling cylinder at this time, sampling needle at the bottom of sampling cylinder is inserted into
suppository bottle after this, the effect of sampling at the same depth can be achieved, and the height of sampling needle extending into
bottle can be adjusted simultaneously.
