Description

A kind of electrical impedance testing cassete
Technical field:
The present invention provides a kind of electrical impedance testing cassete, belongs to electronic information technology, biological medicine technology, mechanical device etc. Field.
Background technology
The electric conductivity of solution or gel is relevant with several factors, the concentration of such as solute, the temperature of solution, solution and test The contact area of electrode, physical form of solution etc..In scientific research, on the one hand, needs probe into impact solution or gel is led Electrical factor.On the other hand, need to prepare the solution with specific electrical conductivity or gel.But, due to solution or gel Mobility, it is in irregular shape, for the accuracy of the conductivity measurement of measured object decreases, simultaneously for measured object electric conductivity The correctness of analysis and analysis efficiency have a significant impact.
Solution or gel have extensive use in many fields, especially are used for imitating the system of body in biomedical engineering field Make.For example in electrical impedance imaging test, imitate tissue using the colloid that NaCl and agar are made into, using NaCl solution with Aluminium bar imitates the limbs of human body and carries out electrical impedance imaging experiment.The making target of imitative body is to make the structure with specific electrical conductivity The similar strong electrolytic solution of body, such as NaCl solution is needed as close possible to human body with the electrical conductivity of the gel for adding ion Conductivity value.Electrical impedance testing cassete is used for the electrical conductivity of the solution and gel for measuring configuration, improves the accuracy of experiment.
The content of the invention
The present invention proposes a kind of electrical impedance testing cassete, present invention achieves the resistance of the solution with mobility or gel Anti- effective measurement, it is so as to improve the efficiency of the accuracy and electric conductivity analysis of the measurement of measured object electrical impedance, as detailed below Description:
A kind of electrical impedance testing cassete, including:Cylinder outward appearance agent structure, the internal rule space for having receiving measured object, two Side is thread plug, on the inside of thread plug, i.e., the side for contacting with measured object, and with reference to electrode, thread plug central punch extraction wire, its In,
Testing impedance box making material is insulator, and its size can be modified before making as the case may be.
The cavity, that is, accommodate the space of measured object, be cylinder or prism.
The both sides thread plug is connected with cylinder by helicitic texture.
On the inside of the thread plug, i.e., the side for contacting with measured object, with reference to electrode, thread plug central punch extraction wire.
The electrode is pellet electrode.
The wire is with electrode by being weldingly connected.
The beneficial effect of technical scheme that the present invention is provided is:
The invention provides a kind of electrical impedance testing cassete, instant invention overcomes liquid or gel have mobility, shape is not The restriction of rule, and electrode accesses uneven shortcoming in test process, improves liquid or gel impedance bioelectrical measurement Accuracy, improves the computational efficiency of other Scientific Indicators such as tester electrical conductivity.

In Fig. 3,2.1 is metal electrode, and 2.2 is wire via.Thread plug portion of the handle shown in Fig. 4 this example is chosen for pros Shape, can be chosen for arbitrary polygon, its object is to be easy to hand-held, prevent testing cassete from rolling.
In Fig. 5,3.1 is wire, and 3.2 is metal electrode.
Below with specific embodiment illustrating a kind of use of electrical impedance testing cassete provided in an embodiment of the present invention, refer to It is described below:
In the case of measurement variable concentrations solute, solution resistance resists.
First with the good solution to be measured of different gradient configurations.
Electrical impedance of outwarding winding testing cassete one end, solution to be measured is injected, vice is screwed.
By two ends wire termination tester, resistance value is measured.
Solution is changed, repeats aforesaid operations.
It will be appreciated by those skilled in the art that accompanying drawing is the schematic diagram of a preferred embodiment, the embodiments of the present invention Sequence number is for illustration only, does not represent the quality of embodiment.
The foregoing is only presently preferred embodiments of the present invention, not to limit the present invention, all spirit in the present invention and Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
