Abstract
The utility model relates to the related technical field of animal tumor volume measuring devices, and in particular relates to an animal tumor volume measuring instrument. The instrument comprises a main body with a hollow cavity, a measuring part which is arranged at one end of the main body, and a pressurizing part which is arranged at the other end of the main body in a sealing manner and pressurizes the gas which is filled in the main body, wherein the measuring part is communicated with the main body. With the animal tumor volume measuring instrument, the error which is caused by estimating the tumor volume in the past is reduced, and the measuring precision is improved. With the instrument, the time for measuring the tumor volume is also shortened, and the quick measurement of animal tumor volumes on a large scale is facilitated.
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: the main body with cavity; With the measurement section that is arranged at main body one end, and sealing is arranged on the pressure-bearing portion that the main body other end is exerted pressure to the gas that is held in the said main body, said measurement section and main body connection.
As a kind of preferred version, said main body is cylindric body.
As a kind of preferred version, said measurement section is for measuring pressure transducer or the mechanical compression table that body interior pressure changes.
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.
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 other end has a pressure transducer 2.
Be illustrated in figure 2 as the work sketch map of present embodiment.
Be placed on this equipment the top of subcutaneous transplantation tumor and press to tumor and make tumor mass promote elastica 3, tumor mass is by elastica 3 parcels, and the gas in the main body 1 is extruded and causes pressure to change.The variation of pressure is received induction by pressure transducer 2, and converts pressure signal the volume of corresponding lump into.
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 volume to convert pressure to and change, the size of gross tumor volume and its pressure that is caused be varied to positive correlation, and the pressure variation can be read through pressure transducer; 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.
Claims (5)
