Electronic weighing medicine spoon device

Abstract

The invention relates to an electronic weighing medicine spoon device. A first assembly is of a shell-shaped structure with an opening in one end, and supporting parts are arranged at the opening of the first assembly in longitudinal symmetry. One end of a second assembly is arranged in the first assembly in a penetrating mode, the second assembly is in multi-point contact or linear contact with the supporting parts of the first assembly, and a medicine spoon fixing part is arranged at the other end of the second assembly and used for fixing a medicine spoon. A pressure sensor, an integrated circuit board and a power source are arranged in the first assembly, and a display screen and a switch are arranged on the shell of the first assembly. The pressure sensor is fixed in the first assembly and arranged above the end, located in the first assembly, of the second assembly. The integrated circuit board is in power supply connection with the power source. and the integrated circuit boardis electrically connected with the pressure sensor, the display screen and the switch. The device is convenient, quick and efficient to operate, and is simpler, more convenient and controllable in operation than decrement weighing when being used for weighing a reagent which is easy to deteriorate in air, so that the weighing time is shortened, and the weighing error is reduced.

Description

technical field

[0001] The invention relates to the field of laboratory experiment instruments, in particular to an electronic weighing medicine spoon device. Background technique

[0002] The existing method of weighing solid samples in the laboratory is: first spread weighing paper on the electronic balance, after peeling the weighing paper, take out the solid sample from the reagent bottle with an ordinary medicine spoon and put it on the electronic balance to weigh. After weighing the required amount of solid sample, transfer the solid sample from the weighing paper to the target instrument.

[0003] This traditional sampling method is not only cumbersome, especially in the process of multiple weighing and sampling, multiple transfers will cause waste of samples, and the use conditions of the electronic balance are relatively harsh. Vibration on the desktop will cause errors in the weighing results.

[0004] In particular, the traditional sampling method is more cumber...
