Abstract
The utility model discloses a kind of magnetic lenses, is made up of permanent magnet and left and right pole shoe, and for forming a very strong line magnetic field, in the occasion for needing to separate magnetic bead, this strong line magnetic field can adsorb magnetic bead into a line.
Description
Technical field
The present invention is a kind of magnetic lenses, more particularly to needs to produce the field in a strong line magnetic field.
Background technology
In many occasions, it is necessary to a strong line magnetic field be produced, in particular with nanometer magnetic bead in recent years in biomedicine
Etc. the application of every field, generally require magnetic bead and the separation of other media.The method of separation can use permanent magnet or electromagnetism
Iron is separated.Due to simple with magnet structure, all separated in many occasions using permanent magnet.During in order to ensure separation
Magnetic bead will not be lost, and both need strong magnetic field, wish that magnetic field can concentrate again, so as to which magnetic bead is adsorbed in specific region.Mesh
Before, in biomedical sector, particularly in automatic chemiluminescence immunoassay system, it is substantially using simple permanent magnetism
Body carries out Magneto separate, and magnetic field is not enough concentrated, and has edge effect, in multiple cleaning process, it is easy to the loss of magnetic bead is caused,
So as to influence the accuracy of testing result.
The content of the invention
In order to solve the technical problem of above-mentioned appearance, the invention provides a kind of simple magnetic lenses, forms strong line magnetic
, magnetic bead can be adsorbed into a line, so as to ensure in multiple cleaning process, magnetic bead will not be lost so that detection knot
Fruit is relatively reliable.Accompanying drawing 1 is the basic structure of this magnetic lenses, is made up of permanent magnet 1, left pole shoe 2, right pole shoe 3, left and right pole shoe
Positioned at the both sides of permanent magnet, the N of permanent magnet, S poles are pull-in on respectively.Left and right pole shoe is made up of the high material of magnetic conductivity, at top
Gradually narrow, gradually narrowed at top, and be parallel to each other at the top of the pole shoe of left and right, form a small gap, in this gap
Place can form a strong line magnetic field.
This magnetic lenses is compact-sized, simply, especially suitable for need to magnetic bead carry out clean separation occasion.
Brief description of the drawings
Fig. 1 is a kind of structural representation of magnetic lenses of the present invention.
Embodiment
The invention provides a kind of simple magnetic lenses, is made up of permanent magnet 1 and left pole shoe 2, right pole shoe 3, left and right pole shoe
Positioned at the both sides of permanent magnet, the N of permanent magnet, S poles are pull-in on respectively.Left and right pole shoe is made up of the high material of magnetic conductivity, at top
Gradually narrow, and be parallel to each other at the top of the pole shoe of left and right, form a small gap, place can form one strong in this gap
Line magnetic field.
Finally it should be noted that：Above example only not limits technology described in the invention to illustrate the present invention
Scheme；Therefore, although this specification with reference to above-mentioned each embodiment to present invention has been detailed description, this
Field it is to be appreciated by one skilled in the art that still can be modified to the present invention or equivalent substitution；And all do not depart from this
The technical scheme of the spirit and scope of invention and its improvement, it all should cover in scope of the presently claimed invention.
