Automatic oscillating and uniform mixing device

Abstract

The invention relates to an experimental device in the field of medicine and biology and particularly relates to an automatic oscillating and uniform mixing device. The device comprises a base, a rocking plate and a rocking box. The rocking plate is arranged on the base. The rocking box is arranged on the upper end surface of the rocking plate and is detachably connected to the rocking plate. Thebase comprises a motor, a driving wheel, a driven wheel and a transmission shaft. The transmission shaft is connected to an oscillating structure. The oscillating structure comprises an eccentric shaft and an eccentric wheel. The lower end surface of the rocking plate is provided with a circular groove and a first annular groove, the wall of the circular groove is provided with a through hole, a raised part and a pushing plate are arranged in the through hole, a second annular groove is arranged around the circular groove, an air bag is arranged in the first annular groove, the eccentric shaftis rotatingly connected to a connection rod, a free end of the connection rod is provided with a cylindrical raised block, the cylindrical raised block is slidingly connected to the interior of the second annular groove, the lower end surface of the base is provided with a support block, a vertical through hole is arranged in the support block, and a gas-guide tube is connected between the vertical through hole and a gas inlet of the air bag. The experimental device can automatically oscillate and mix the sputum samples in batches.

Description

technical field [0001] The invention relates to experimental equipment in the fields of medicine and biology, in particular to an automatic oscillating and mixing device. Background technique [0002] Sputum is the secretion of the trachea, bronchi, or alveoli. Under normal circumstances, the glands and goblet cells of the bronchial mucosa secrete a small amount of mucus to keep the mucous membrane of the respiratory tract moist; Necrosis products etc. are mixed to form sputum. [0003] There are many kinds of bacteria contained in sputum, and sputum examination is a means for hospitals to test respiratory diseases. Put it into the sputum cup, in order to speed up its dissolution, the doctor shakes it by hand for 10-15 minutes. For doctors, if there are too many specimens, the workload will be large, and manual shaking will cause arm soreness, and the effect of manual shaking is not good. From the perspective of application, the purpose of sputum oscillation is to prepar...

AI Technical Summary

Problems solved by technology

At present, the manual oscillation of hospital doctors not only cannot ensure the consistency of specimen mixing effect, but also reduces work efficiency

At present, there are many kinds of medical mixing devices on the market, which are used for mixing various test solutions. However, most of the mixing devices are unidirectional oscillation mixing, which is more prone to problems such as uneven mixing compared with circumferential oscillation mixing.
