Description

Technical Field

[0001] The utility model relates to the technical field of liquid medicine measuring equipment, and more specifically, to a novel liquid medicine density measuring device. Background Art

[0002] Ensuring that the density of pharmaceutical solutions remains within specified limits is crucial during pharmaceutical production and quality control, as it can impact drug stability, efficacy, and dosing accuracy. For novel pharmaceutical solutions, the specific composition of these solutions may necessitate adjustments to traditional density measurement methods or the development of new measurement techniques. Furthermore, the physicochemical properties of novel pharmaceutical solutions (such as solubility and viscosity) may affect density determination and therefore need to be considered when developing measurement methods.

[0003] When measuring the density of liquid medicine, a measuring scale and a density meter need to be used in conjunction with each other. When people place the liquid medicine on the measuring scale, the contact surface is very smooth, which can easily reduce the stability of the measuring cylinder. If people accidentally touch the measuring cylinder, it may cause the liquid medicine to shake, thereby increasing the measurement error. When the density meter is placed vertically inside the measuring cylinder, it will produce a certain degree of shaking, and people need to constantly adjust it, which reduces the measurement efficiency.

[0008] As a preferred technical solution of the present invention, the cross section of the bracket is C-shaped, and the brackets are symmetrically arranged on both sides of the carrier plate, so that the density meter can be placed between the brackets.

[0009] As a preferred technical solution of the present invention, a pad is fixed at one end of the second screw rod, and the pad is made of rubber material, which is convenient for fixing the hook.
