Description
Technical field
The utility model relates to mouse cell strain inoculation tumor formation model or Transplanted tumor models in a kind of oncology correlative study
Experimental tool more particularly to a kind of quick mouse subcutaneous tumor volumes measuring tool.
Background technique
Currently, establishing, mouse subcutaneous cell strain is inoculated with tumor formation model or Transplanted tumor model is common in oncology correlative study
A kind of technological means, by observe mouse subcutaneous tumor growing state, a series of scientific researches are unfolded.Laboratory is seen at present
The growing state for examining mouse subcutaneous tumor mainly passes through rough measure and observation gross tumor volume.Common method is to use vernier calliper
Ruler records tumour longest diameter (L) and vertical direction maximum transverse diameter (W), according to formula V=LW2/ 2 calculate gross tumor volume.Method behaviour
Although work is not difficult, measurement error is big, and time-consuming, generally requires two people's cooperations.Recent years abroad develops a kind of tumour tracking system
System, can draw tumour 3D rendering, and calculated in 0.1 second, and data accuracy is high, easy to operate, but price is very expensive.
Summary of the invention
In order to solve the above shortcomings in the prior art, the utility model provides a kind of quick mouse subcutaneous tumor volumes to survey
Amount tool.
In order to solve the above-mentioned technical problem, the utility model uses a kind of following technical scheme: quick mouse subcutaneous tumor
Volume measurement tool, including measurement handle, the top of the measurement handle are equipped with a limit and adjust sliding slot, and the limit is adjusted
Measurement sliding block is installed on sliding slot, is equipped with L-shaped extension support arm on front side of the measurement sliding block, under the front end of the extension support arm
The fixed activity measurement folder in side end, the opposite side of the activity measurement folder is equipped with the fixation measuring for being fixed on measurement handle
Folder, the front of the fixation measuring clamp is equipped with longitudinal airborne laser range finder that a row is mounted on the downside of measurement handle, and the fixation is surveyed
The folder inner wall of amount folder is equipped with the lateral airborne laser range finder for measuring spacing between fixation measuring clamp and activity measurement folder;It is described
While tumour subcutaneous with fixation measuring clamp clamping mouse is pressed from both sides in activity measurement, the longitudinal direction airborne laser range finder and lateral laser ranging
Device calculates separately out the vertical direction maximum transverse diameter (W) of tumour and the longest diameter (L) in tumor levels direction.
Further, the inside of the measurement handle is additionally provided with the computing controller of the volume for calculating tumour, institute
It states computing controller and is connected to longitudinal airborne laser range finder and lateral airborne laser range finder.
Further, it is described measurement handle side be equipped with one for show calculate after tumour (9) volumetric quantities show
Display screen, the display screen are controlled by the computing controller and are connected.
Further, the top of the measurement sliding block be equipped with for control computing controller start longitudinal airborne laser range finder and
The start button of lateral airborne laser range finder work.
Further, the guide chute of one section of transverse direction is additionally provided on front side of the measurement handle, before the extension support arm
End is equipped with matching and is inserted into guide pad in guide chute.
Further, there is certain gap, the longitudinal direction laser ranging between the activity measurement folder and measurement handle
Device is placed between the gap, and the upside outer wall of activity measurement folder has the laser barn door being laterally arranged.
The working principle of the utility model is that the key of acquisition mouse subcutaneous tumor volumes rough figure is to obtain tumour most
Long diameter (L) and vertical direction maximum transverse diameter (W) the two numerical value realize the fast of data using laser distance measuring principle based on this
Speed obtains.Pass through, fixation measuring clamp and activity measure the diameter that clamp lock determines tumour, and fixation measuring clamp and activity measurement folder are had to
Perpendicular to tumour, fixation measuring clamp is equipped with lateral airborne laser range finder, to measure the distance between two card slots, i.e. tumour most
Long diameter (L), that is, the diameter of tumour.
Longitudinal airborne laser range finder of top dense arrangement between fixation measuring clamp and activity measurement inside issues infrared ray,
Start button is pressed, in infrared radiation to tumour.Since ideal tumour is a cambered surface, when infrared ray impinges upon above, one
The problem of a little infrared rays can be due to angle of reflection and can not backtracking laser emitter, cause no data, still, practical situation
It is mouse subcutaneous tumor often without so rule, has several laser emitters and receive signal, preferably, impinge upon tumour highest
The infrared ray of point should can be reflected back transmitter.Laser emitter receives signal, and program calculates distance automatically, and therefrom
Minimum value is filtered out, the vertical range at laser emitter to card slot tip is fixed value, which subtracts above-mentioned minimum value, i.e.,
For tumour vertical direction maximum transverse diameter (W), that is, the height of tumour.
The program of computing controller presses formula V=LW after obtaining the two values automatically2/ 2 are calculated, and by result
Display is on a display screen.Can also directly it be connected with computer, it will be in data inputting Microsoft Excel.
Compared with prior art, the utility model solves conventional method using operating in vernier caliper measurement gross tumor volume
Inconvenience, the big problem of data error, and entire compact volume and convenience, it is low in cost, the working efficiency of laboratory technician can be significantly improved.
