CN201036553Y - Experimental device for measuring animal toe swelling - Google Patents

Abstract

The utility model discloses an experimental device for testing the swelling of the toes of the animals, consisting of a test tube(1) and an electronic scale(2). The experimental device is characterized in that the top of the test tube(1) has an opening which is connected with a conduit which bends downwards horizontally, and the exceeded liquid is led into the electronic scale(2) during the test.

Description

A kind of experimental provision of measuring the swelling of animal toes

Technical field

This utility model relates to a kind of experimental provision of measuring the swelling of animal toes.

Background technology

Rat toes inflammation swelling method is a most frequently used acute nonspecific inflammation model in the anti-inflammatory drug experiment.The method of measuring the swelling degree comprises Zhou Changfa, thickness method, volumetric method or glass volumetric method.Wherein, it is bigger that girth or thickness method are influenced by subjective factors, and accuracy and repeatability are relatively poor.Volumetric method is comparatively commonly used, also relatively accurately.But equipment therefor and method are all very complicated, are not easy to a large amount of zooperies.Read the glass-tube scale and also have personal error, and the selected container operation of glass container method is also convenient inadequately.All exist owing to arresting the operation inconvenience that difficulty is brought when simultaneously, regaining consciousness rat experiment with above-mentioned all methods.

Summary of the invention

This utility model patent purpose is to provide the device of swelling degree of the paw under a kind of simple, rapid, accurate, safe mensuration animal waking state.

This utility model patent is achieved in that the device of measuring the swelling of animal toes, it is characterized in that being made up of test tube and electronic balance filled with fluid in test tube during measurement.Another feature of measuring the device of animal toes swelling is that there is an opening on the test tube top, and opening part connects the downward conduit of a level, and the liquid with overflow during measurement imports in the electronic balance, and measurement is that the liquid in the test tube is hydrargyrum.This utility model patent optimized technical scheme is with diameter 2cm, and the teat glass of high 8～10cm is fixed on the iron stand, places a digital electronic balance, sensibility reciprocal 0.1g, one bottle of hydrargyrum under test tube. one on the clear-headed rat experiment cover of taper.During measurement, catch rat tails on the other hand, the closing in rope of another portable firmly Mus cover allows rat creep into the Mus cover naturally.Tighten up rope, fasten.A little hydrargyrum is overflowed naturally the hydrargyrum injecting tube from test tube and fall into balance on goods and services, the hydrargyrum weight that recording balance shows is as basis weight.In Mus cover, draw out hind leg to be measured, it is stretched fixing, immerse in the hydrargyrum of test tube, make the hydrargyrum liquid level equal, the hydrargyrum true weight of recorded electronic balance demonstration with aganil pad upper limb.Deduct the weight that the hydrargyrum basic weight is the hydrargyrum of this foot sole of the foot discharge with the hydrargyrum true weight, be converted into volume as required.

The swelling degree of the paw coefficient of variation with this device bioassay standard thing and normal rat is little, and repeatability is fine. and error is little, the accuracy height, the assurance tested animal is carried out the mensuration of toes swelling volume under waking state.

The specific embodiment

With reference to accompanying drawing, according to example in detail of the present utility model.

As shown in Figure 1, measure the experimental provision of animal toes swelling,, fill hydrargyrum in the teat glass 1 of high 8～10cm diameter 2cm.Under test tube, place a digital electronic balance 2, sensibility reciprocal 0.1g, one bottle of hydrargyrum. one on the clear-headed rat experiment cover of taper.During measurement, catch rat tails on the other hand, the closing in rope of another portable firmly Mus cover allows rat creep into the Mus cover naturally.Tighten up rope, fasten.A little hydrargyrum is overflowed naturally the hydrargyrum injecting tube from test tube and fall into balance on goods and services, the hydrargyrum weight that recording balance shows is as basis weight.In Mus cover, draw out hind leg to be measured, it is stretched fixing, immerse in the hydrargyrum of test tube, make the hydrargyrum liquid level equal, the hydrargyrum true weight of recorded electronic balance demonstration with aganil pad upper limb.Deduct the weight that the hydrargyrum basic weight is the hydrargyrum of this foot sole of the foot discharge with the hydrargyrum true weight, be converted into volume as required.

Claims (4)

1. an experimental provision of measuring the swelling of animal toes is made up of test tube (1) and electronic balance (2), it is characterized in that there is an opening on test tube (1) top, and opening part connects the downward conduit of a level, and the liquid with overflow during measurement imports in the electronic balance.

2. the described device of claim 1, filled with fluid in the test tube when it is characterized in that measuring.

3. the described device of claim 1 is characterized in that described liquid is hydrargyrum.
