Medicine spoon for accurate weighing and sample addition

Abstract

The invention discloses a medicine spoon for accurate weighing and sample addition. The medicine spoon comprises a spoon head, a handle and a vibration device arranged in the cavity of the interior ofthe handle, wherein the cavity of the interior of the handle is also provided with an adjusting device and a control device connected with the vibration device and the adjusting device; the adjustingdevice is used for adjusting the vibration intensity required by the medicine spoon and sends sending an adjusting signal to the control device; and the control device is used for treating a receivedadjusting signal to adjust the vibration intensity of the vibration device, thereby controlling the vibration strength of the handle. According to the invention, during accurate weighing of a powdersubstance, through vibration of the vibration device, the fluidity of the powder substance is reinforced; the sample addition speed and the sample addition amount of the powder substance can be conveniently controlled; the situation that an excessive addition amount of the powder substance is added is not generated during weighing of the powder substance; and repeated weighing operation due to excessive sample addition is greatly reduced.

Description

technical field [0001] The invention relates to a chemical analysis device used for taking and weighing powdery substances, which can avoid cross-contamination, in particular to a medicine spoon for accurate weighing and adding samples. Background technique [0002] In chemical and physical analysis laboratories, medicine spoons are usually used to take and weigh powdery substances. Especially when weighing accurately, one must be accurate and fast, and the other is to prevent cross-contamination. The usual experimental steps are: prepare the balance, put the weighing container (or weighing paper) on the balance tray, then take the powder material from the medicine spoon and add it to the container, when the weight is close to the requirement, pat the hand holding the spoon with your hand Wrist, so that the powder material is slowly added to the container to achieve the specified amount to balance the balance. When changing a variety or batch number to weigh, it is usually ...

AI Technical Summary

Problems solved by technology

However, the electric medicine spoon can only maintain one vibration frequency when in use, and cannot adjust the vibration intensity of the handle according to the actual needs of the user, and control the sample addition speed and sample volume. precise control

In addition, the spoon head and handle of the electric medicine spoon are not detachable. When the spoon head needs to be replaced, the whole medicine spoon needs to be replaced or cleaned again, which is still inconvenient to operate.
