Abstract
The utility model relates to the related technical filed of animal tumor volume measuring instruments, and in particular to an animal tumor volume measuring instrument; the instrument comprises a main body capable of containing liquid, a measuring part arranged at one end of the main body and a pressure-bearing part, wherein the pressure-bearing part is arranged at the other end of the main body in sealing manner and exerts pressure upon the liquid contained in the main body; the measuring part is communicated with the main body; and the liquid contained in the main body can enter the measuring part under the pressure of the pressure-bearing part. The animal tumor volume measuring instrument reduces the error of estimating the animal tumor volume formerly, and improves the accuracy of measurement. The device further reduces the time of measuring animal tumor volume, and is convenient to quickly measure the animal tumor volume in large quantities.
Description
Technical field
This utility model relates to animal tumor measuring device correlative technology field, particularly a kind of animal tumor cubing instrument.
Background technology
When assessment of cancer was treated, the size of measuring tumor was very important link in the zooscopy before clinical.Like Euhus DM; Hudd C, LaRegina MC, Johnson FE:Tumor measurement in the nude mouse. J Surg Oncol 1986; 31:229-234 and Tomayko MM; Reynolds CP:Determination of subcutaneous tumor size in athymic (nude) mice, Cancer Chemother. Pharmacol 1989,24:148-154 is said; In these researchs, a kind of method of continuous measurement gross tumor volume of Noninvasive is absolutely necessary.The standard technique of measuring subcutaneous tumor volumes at present is by outside slide calliper rule, uses amended ellipsoid formula to calculate gross tumor volume 1/2 (length x width 2) and calculates.The method is used the metering system (length and width) of two dimension, estimates three-dimensional measurement result (volume).Because the height of tumor can't be measured, use this formula to calculate a just estimated value of tumor size.The height of Subcutaneous tumor is even the standard of use slide calliper rule also are difficult to measure.In addition, the Subcutaneous tumor length of use kind of calliper and width are also often owing to the irregular error of tumor shape is affected.
The utility model content
This utility model provides a kind of animal tumor cubing instrument, to solve the technical problem that prior art exists.
This utility model adopts following technical scheme to realize:
A kind of animal tumor cubing instrument; Said instrument comprises: but the main body of receiving fluids; With the measurement section that is arranged at main body one end; And seal the pressure-bearing portion that the main body other end is exerted pressure to the liquid that is held in the said main body that is arranged on, and said measurement section and main body are communicated with, and the liquid that is contained in body interior can get into measurement section under the exerting pressure of pressure-bearing portion.
As a kind of preferred version, said main body is cylindric body.
As a kind of preferred version, said measurement section is a graduated cylinder, and the graduated cylinder surface is provided with the scale that is used for the marking liquid volume.
As a kind of preferred version, said pressure-bearing portion is arranged on the elastica of measurement section bottom for sealing.
Preferably, said elastica is a rubber membrane.
As a kind of preferred version, the sectional area of said pressure-bearing portion is greater than the sectional area of said measurement section.
This utility model has reduced the error of in the past estimating animal tumor volume size, has improved measuring accuracy.This equipment has also reduced the time of measuring the animal tumor volume, is convenient to the animal tumor volume of measuring fast in enormous quantities.
Description of drawings
Fig. 1 is the structural representation of this utility model;
Fig. 2 acts on the structural representation that animal tumor is measured for this utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment this utility model is done further detailed explanation.
Be illustrated in figure 1 as the structural representation of this utility model; The equipment of present embodiment comprises the main body 1 that a columniform plastic tube or other material constitute; One end of main body 1 is with elastica 3 (for example rubber membrane) or other material seal; Be described pressure-bearing portion, main body 1 one ends have a less graduated cylinder that has rule 2.Be full of liquid in this equipment, band or not colored water or other liquid.
Be illustrated in figure 2 as the work sketch map of present embodiment.
Be placed on this equipment one end of subcutaneous transplantation tumor and press to tumor mass 4 and make tumor mass 4 promote elasticas 3, tumor mass 4 is by elastica 3 parcels, and elastica 3 is extruded upwards, and the liquid in the main body 1 is extruded rising.The volume of ascending liquid equates that with the volume of tumor mass 4 this volume can be read through the reading on graduated cylinder 2 rules.
Compared with prior art; The present invention has considered the error that kind of calliper Subcutaneous tumor length and width cause owing to tumor shape is irregular; Utilize the volume conversion, the size of gross tumor volume equals to be extruded the size of liquid volume, and the liquid volume that is extruded can be read through the rule reading; Like this, can make the measurement of gross tumor volume avoid the error that causes owing to tumor shape is irregular and more approach actual value.
