Abstract

The invention relates to the technical field of medicine preparation auxiliary devices, in particular to a slow-dripping device for preparing an antiviral drug HIV intermediate. The device comprises a workbench, wherein a placement plate is fixedly mounted at the center of the upper surface of the workbench, L-shaped splash-proof guard plates are vertically fixed to the left side and the rear side of the upper surface of the workbench, a liquid storage bottle is fixedly mounted above the surface of the long edge of the L-shaped splash-proof guard plate through a mounting frame, a slow dripping assembly is arranged below the liquid storage bottle, and a buffer assembly is arranged on the surface of the L-shaped splash-proof guard plate and located on the right side of the slow dripping assembly. According to the invention, the sliding lead of the slow dripping plate is changed along with the change of the expansion and contraction amount of the telescopic end of a small hydraulic cylinder, then the slow dripping holes with different sizes are aligned with the flow guide holes, the dripping speed of liquid medicine can be effectively adjusted, the slow dripping speed of the device is adjusted, the slow dripping speed is controlled, the use requirements under different conditions are met, and the dispensing accuracy is further improved.

Description

technical field [0001] The invention relates to the technical field of auxiliary devices for preparation of medicines, in particular to a slow-drip device for preparing HIV intermediates of antiviral drugs. Background technique [0002] The disease caused by HIV infection is called AIDS, and its full name is Acquired Immunodeficiency Syndrome. The patient's immune function is partially or completely lost, and the number of CD4+ cells is reduced, followed by opportunistic infection or tumor. The clinical manifestations are various. Diverse, when preparing antiviral drug HIV intermediates, when using a dropper for dripping, traditional dripping equipment cannot grasp the rate of dripping well through manual dripping, and thus cannot adjust the rate of dripping , so when preparing the drug mixture, it causes a large error. In view of this, we propose a standby slow drop device for antiviral drug HIV intermediates. Contents of the invention [0003] The object of the present ...
