Weighing medicine box

Abstract

The invention provides a weighing medicine box. The weighing medicine box comprises an outer box with an open top, wherein the top of the outer box is covered with a box cover, the box cover is rotatably pivoted with the outer box, the box cover is connected with the outer box through a switch device, the switch device can control the opening and closing of the box cover, a weighing sensor is arranged on a bottom plate of the outer box, a tray is arranged on the weighing sensor, the tray is provided with an object-containing box, lifting devices are separately arranged between the outer wallsof two ends of the object-containing box and the inner walls of two ends of the outer box, and the lifting devices are connected with the box cover and the outer box. According to the weighing medicine box, through the lifting devices, when the box cover is opened, the object-containing box is separated from the tray, and when the measured medium is taken from the object-containing box at the time, the force received by the object-containing box cannot be transmitted to the tray and the weighing sensor, thus the inaccurate weighing caused by repeated stress of the weighing sensor is directly avoided; and in addition, when the object-containing box is separated from the tray, the weighing sensor can be conveniently calibrated without taking out the measured medium in the object-containing box, so that the calibration operation is very convenient.

Description

technical field [0001] The invention relates to a medicine reserve monitoring device, in particular to a weighing medicine box. Background technique [0002] Weighing technology is widely used in the field of civilian automatic packaging machinery, and automatic weighing technology is also used in medicine cabinet products in the medical industry to measure weight to achieve the purpose of counting. It is mainly used to measure and monitor various injections and powder injections The advantages of weighing and counting are that it is not limited by physical factors such as the shape, material, and transparency of the measured medium. It has a wide range of applications, high measurement accuracy, high accuracy, and flexible configuration. flexible. [0003] The existing weighing medicine boxes all adopt a load cell for weighing, and a storage box is arranged on the load cell, and the measured medium is stored in the storage box. During use, since the load cell and the stor...

AI Technical Summary

Problems solved by technology

During use, since the load cell and the storage box are fixed together, the operator will touch the storage box when taking and placing the measured medium from the storage box, thus indirectly exerting force on the weighing box. On the sensor, the zero point drift of the load cell is caused or even permanently damaged, resulting in the actual zero point value being larger or smaller than the pre-calibrated recorded value, resulting in inaccurate weighing. Therefore, it is necessary to perform zero point calibration on the load cell frequently, increasing operator workload

[0004] Moreover, when performing zero point calibration, all the measured medium must be taken out of the storage box, leaving only the load cell itself and the storage box fixed on the load cell, and this operation is not ideal in reality. For some stored measured media that may not be used for a long time, it will not only take a lot of time for medical workers to repeatedly take the measured media out of the storage box for calibration and then put the test object back into the storage box. It may also cause pollution to the measured medium, which is very inconvenient to use
