Description
Technical field
The invention belongs to swelling field of measuring technique, relate in particular to a kind of swollen tissue measuring instrument and control method thereof.
Background technology
In biological experiment, having a class experiment is by various means induced tissue edema, between matched group and experimental group, by measuring the degree of edema, is studying the biological action that intervention factor plays in this process.
Be mainly to change to reflect swelling degree by tissue thickness before and after measuring edema at present, the comparatively general instrument of application has the diastimeter of slide gauge and industrial measurement cylinder, ball diameter.But such instrument is mainly applicable to measure the object with some strength, when two find range end points and object close contacts of survey tool, object under test deformation is minimum, negligible; Thereby the distance between two range finding end points is required length to be measured.And swelling tissue elasticity is very large, slight pressure can produce compared with large deformation.For example, 5～8 week age, experiment mice ear thickness generally had 0.25mm thickness, after swelling, can reach 0.2～0.45mm.The power that manual moving cursor slide calliper rule produce is easy to push swelling ear to be measured, the reading recording has the error of 0.2～0.8mm, and the subjective factorss such as this error and operator's maneuver, range estimation custom, reading custom have very big relation, the data difference that different operating person repeats is very big, when the data of two different disposal groups contrast, false positive or false negative rate are high.The another kind of subjective error that has been overcome to a certain extent manual slide gauge by the range finding instrument of spring driven electronics automatic reading, the spring still with different coefficient of elasticity still has certain extruding force to specimen.In actual mechanical process, when two of survey tool range finding end points all contact with specimen, (now electronical reading is actual (real) thickness, but gauger cannot judge the reading when reading is actual (real) thickness) to final electronical reading while stablizing, this electronical reading changes not stopping; And when electronical reading is stablized (3 second reading do not change), can obviously see that swelling tissue surface has the formed indenture of pressurized (in different swelling degree situations, it is dark that this indenture can reach about 0.1mm, have a strong impact on actual result), illustrate that this reading is less than actual swelling thickness, this situation, has dwindled swelling degree difference, as easy as rolling off a logly causes false-negative result.
Its operation principle of light calibrator can be to body surface build-up of pressure to be measured, but the hair of organism surface perk, scurf etc. can interferometries, and reading is increased.
In addition, show as in appearance the swelling body of same degree bulge, its content may have very big-difference, and content is that the swelling meeting of hypertrophy solid tissue is that the swelling of mobility liquid is more hard than content.Therefore, except measuring the dimensional variation of swelling generation, its swelling character is also an important parameter, and also there is no to measure at present the instrument of swelling character.
