Multifunctional accurate weighing and sampling medicine spoon for laboratory

Abstract

The invention discloses a multifunctional accurate weighing and sampling medicine spoon for a laboratory. The medicine spoon comprises a replaceable spoon head and a spoon handle main body; a miniature electronic scale and vibrators are arranged in the spoon handle; the vibrator on the spoon body and the vibrator on a weighing rod can be switched to work according to two different working modes, the flowability of medicines is increased; and a deflector rod is arranged, the deflector rod is effectively combined with a C-shaped regulator which is more consistent with the manual efficiency, so that the medicines can be finely adjusted under the condition that the friction force between the medicines is greater, the reliability of the equipment is improved; the weighing device of the spoon isbased on a balance balance scale, is provided with a balance weight and an inductor, and therefore, under the indication of an LED display, weighing precision can achieve amilligram level; an LED lamp is arranged at the front end of the spoon handle, power is supplied to the interior of the spoon handle through a rechargeable battery, and program setting and data exporting can be conducted; and through the two different working modes, the working efficiency is greatly improved, and the sample weighing time is saved.

Description

technical field [0001] The invention relates to a medicine spoon used in a laboratory, in particular to a laboratory multifunctional medicine spoon for accurate weighing and sampling. Background technique [0002] In the laboratory, it is usually necessary to take various bottled medicines with a medicine spoon, and quantitatively weigh them with a weighing balance. Sometimes the required weighing accuracy is very high, reaching the level of milligrams or even higher. When weighing, many powdered medicines will be If they are glued together, a large piece of medicine will fall off with a slight shake, resulting in over-weighing, and it needs to be retrieved, resulting in waste of medicine, wasting time, and reducing work efficiency. Moreover, when weighing, it is necessary to Certain skills and proficiency are required to carry out weighing work. [0003] When weighing medicines in the laboratory, there is generally no intuitive feeling for the weight of the medicines, and ...

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 cannot be disassembled. 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; Chinese invention patent (201811485577.0) discloses a The medicine spoon used for adding samples is composed of a spoon head, a handle and a vibrating device installed in the inner cavity of the handle. The inner cavity of the handle is provided with a control device connected to the vibrating device and the adjusting device, so as to control the vibration intensity of the handle. The device vibrates to enhance the fluidity of the powder material, but it can be seen from its drawings and descriptions that its weighing accuracy is low. It can be seen that its weighing device is at the back, and the gravity signal is mainly converted into a pressure signal through an inductor. Weighing, but the medicine spoon part is in the front, and the weighing part is in the rear. In this way, when weighing the medicine, it can be known through the lever principle that the position of the medicine on the medicine spoon will affect the specific value of weighing, resulting in weighing Inaccurate, and its function is single, the artificial efficiency is unreasonable, and the intelligence is low

Chinese invention patent (202010161173.7) discloses an electronically controlled medicine spoon used in pharmacy, which is composed of a handle body, a controller surface, a first spoon head, and a second spoon head. Through hole, the display is embedded on the left side of the top of the main body, and the controller panel is embedded on the right side close to the display, which can measure and obtain the drug value, but the design of the spoon body is relatively large, and the weighing can only reach the level of one gram , not suitable for laboratories to weigh drugs
