Preparation method of lobeline hydrochloride injection

Abstract

The invention discloses a preparation method of a lobeline hydrochloride injection, which comprises the following steps: a lobeline hydrochloride solid raw material is placed in an automatic weighingand feeding device in advance, and a material placing device comprises a feeding bin and a feeding poking sheet; the first metered solid raw material is conveyed into the feeding bin by adopting the automatic weighing and feeding device; a linear driving mechanism is adopted to drive the feeding poking piece to move from the front end wall to the rear end wall of the feeding bin, so that solid rawmaterials are fed into a primary liquid preparation tank; a first liquid metering pump is adopted to convey the second metered water for injection from a liquid storage tank to the primary liquid preparation tank, so that primary prepared liquid is prepared; the activated carbon is conveyed into the primary liquid preparation tank through activated carbon storage equipment; the liquid in the primary liquid preparation tank is filtered through a filter by adopting a second liquid metering pump, and then the filtered liquid is conveyed into a secondary liquid preparation tank; and a third liquid metering pump is adopted to convey the water for injection in the liquid storage tank into the secondary liquid preparation tank. According to the invention, the preparation efficiency and the preparation precision of the lobeline hydrochloride injection are improved to a great extent.

Description

technical field [0001] The invention relates to a preparation method of lobeline hydrochloride injection. Background technique [0002] Lobeline hydrochloride injection is used for respiratory depression and neonatal asphyxia caused by various reasons. It can stimulate carotid sinus and aortic body chemoreceptors (both N1 receptors), and reflexively excite the respiratory center to accelerate breathing, but has no direct excitatory effect on the respiratory center. It also has a reflex excitatory effect on the vagus nerve center and vasomotor center at the same time; it excites the autonomic ganglion first and then blocks it. However, the current preparation method of lobeline hydrochloride injection still has the defects that the degree of automation is not high enough and the preparation efficiency needs to be improved. Contents of the invention [0003] An object of the present invention is to solve at least the above problems and / or disadvantages and to provide at le...
