Abstract
The utility model relates to a kind of magnetic stirring apparatus, described magnetic stirring apparatus comprises stirring motor, mounting base, permanent magnet, magnetic grain, sample box, described mounting base is installed with stirring motor, the output shaft of described stirring motor is equipped with permanent magnet, described sample box is placed on permanent magnet front, is placed with the magnetic grain for stirring in sample box.The utility model operates health, mixing speed is fast, mixing uniformity good.
Description
Technical field
The utility model relates to medical instruments field, particularly relates to the magnetic stirring apparatus of a kind of experiment or inspection.
Background technology
In the checkout procedure of human or animal's excretion thing, present hospital uses little plastic cup and cotton swab, or uses little bamboo clappers and little spoon to sample.Then the sample that these gathered of reviewer, get by rule of thumb, add appropriate diluent glass bar and stir, furnishing suspension, spreads upon on slide and is placed in basis of microscopic observation, then records the result of observation, provides survey report.Stir owing to adopting glass bar and be difficult to stir, and easily in the process stirred, cause sample liquid to spill, both have impact on the accuracy of detection, also there is the problem of biochemical safety.
So we have suggested magnetic agitation, by experiment, we find that existing magnetic stirring apparatus exists the problem that Magnetic Field Design is not concentrated, magnet is not easy to installation, efficiency is low, the design of magnetic grain is unreasonable, whipping performance is not high.
Utility model content
The purpose of this utility model is the deficiency overcoming above-mentioned technology, provides a kind of magnetic stirring apparatus meeting bio-safety and require, do not need artificial stirring, mixing effect superior.
The concrete technical scheme of the utility model is as follows:
A kind of magnetic stirring apparatus, comprise stirring motor, mounting base, permanent magnet, magnetic grain, sample box, it is characterized in that: described mounting base is provided with a centre bore, described stirring motor is fixed on mounting base, and the output shaft of stirring motor is connected with permanent magnet by centre bore, described permanent magnet is circular arc with well, circular arc makes magnetic field more concentrated, described sleeve pipe is screwed on the output shaft of stirring motor, described sample box is placed on permanent magnet front, the magnetic grain for stirring is placed with in sample box, described magnetic grain is spheroidal, magnetic grain surface is provided with several being used for and improves the circular knife stirring and play dissection.
The utility model adopts circular arc permanent magnet with well, and installation and removal are convenient, and magnetic field focuses on concentrated more, stronger to the magnetic grain active force in sample box; Magnetic grain is spheroidal, magnetic grain surface is provided with several being used for and improves the circular knife stirring and play dissection, under rotating excitation field effect, fully stir the excretion thing solution in sample box, cut, its mixing effect is much better than artificial stirring and common magnetic stirring apparatus.The utility model operation health, sample stirs uniformity more, and mixing speed is faster, efficiency is higher, is conducive to improving the degree of accuracy detected, and also improves the biochemical safety of sample operation simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In accompanying drawing: 1-stirring motor, 2-mounting base, 3-permanent magnet, 4-sample box, 5-magnetic grain, 6-screw, 7-sleeve pipe, 8-circular knife.
Detailed description of the invention
As shown in Figure 1, a kind of magnetic stirring apparatus, comprise stirring motor 1, mounting base 2, permanent magnet 3, magnetic grain 5, sample box 4, described mounting base 2 is provided with a centre bore, described stirring motor 1 is fixed on mounting base 2, and the output shaft of stirring motor 1 is connected with permanent magnet 3 by centre bore.Permanent magnet 3 is the circular arc of band sleeve pipe 7, and circular-arc-shaped design is ingenious, magnetic field is focused on more concentrated, stronger to magnetic grain 5 active force in sample box 4, also improves device efficiency simultaneously, decreases energy consumption.The sleeve pipe 7 of permanent magnet 3 is fixed on the output shaft of stirring motor 1 with screw 6.
Sample box is placed on permanent magnet front, is placed with the magnetic grain 5 for stirring in sample box, and magnetic grain 5 is spheroidal, and magnetic grain 5 surface is provided with several being used for and improves the circular knife 8 stirring and play dissection.Circular knife 8 is arrangement in different directions, when stirring motor 1 drives permanent magnet 3 to rotate, form the magnetic field of conversion, magnetic grain 5 does not stop to rotate under the effect in conversion magnetic field, excretion thing solution in circular knife 8 pairs of sample boxs 4 on magnetic grain surface fully stirs, cuts, and its mixing effect is better than artificial stirring and common magnetic stirring apparatus.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvement do not departed under the utility model principle prerequisite and modification, these improve and modify and also should be considered as protection domain of the present utility model.
