A gasket is fixedly connected to the bottom side wall of the pull ring.

Beneficial effects of the utility model: The utility model is provided with a stable drug delivery device for intracardiac post-operative care. The threaded block is first rotated, and the threaded block will move on the outer wall of the threaded rod, and the clamp plate is fitted with the collar to limit the The injection volume is limited by the collar, and then when the piston rod is pushed, the piston rod will drive the hollow rod to be sleeved with the threaded rod. When moving a certain position, the hollow rod will fit with the threaded block to limit the position. The amount of the injected drug should be controlled to avoid slight deviations during injection and prevent deviations from affecting postoperative recovery.

Detailed ways

Please refer to FIG. 1 and FIG. 2 , the present utility model provides a technical solution: a stable drug delivery device for intracardiac postoperative care, comprising a syringe 1, and an outer plate 3 is fixedly connected to the top and side walls of the syringe 1 , the inner cavity of the syringe 1 is equipped with a piston rod 2, the bottom side wall of the piston rod 2 is symmetrically and fixedly connected with a hollow rod 4, the outer side wall of the hollow rod 4 is in clearance fit with the outer plate 3, and the inner cavity of the hollow rod 4 is equipped with a thread Rod 5, the bottom side wall of the threaded rod 5 is fixedly connected with a bottom block 6, the inner side wall of the bottom block 6 is fixedly connected with the needle cylinder 1, the outer side wall of the threaded rod 5 is threadedly connected with a threaded block 8, and the outer side wall of the threaded block 8 is symmetrical The clamping plate 9 is fixedly connected, the outer side wall of the needle cylinder 1 is equipped with a collar 10, and the outer side wall of the collar 10 is fitted with the clamping plate 9. When in use, first turn the threaded block 8, through the characteristics of the thread, the threaded block 8 will move on the outer wall of the threaded rod 5, limit the position through the clamping plate 9 and the collar 10, at the same time drive the collar 10 to slide, limit the injection volume through the collar 10, and then push the piston rod 2 When moving, the piston rod 2 will drive the hollow rod 4 to be sleeved with the threaded rod 5. When moving to a certain position, the hollow rod 4 will fit with the threaded block 8 to limit the position, which can control the amount of the injected drug and avoid the occurrence of Weak deviation to prevent deviation from affecting postoperative recovery.
