Not less than the upper port of measuring cylinder, be carved with index line on the outer wall of sighting tube, index line close to sighting tube not with measuring cylinder phase
One end even, and index line is not higher than the upper port of measuring cylinder；The lower port of measuring cylinder is connected with the one end for connecting hose, even
One interface of the other end and threeway that connect hose connects, and the another two interface of threeway passes through hose respectively and is connected with syringe.
Measuring cylinder is funnel-shaped, and the lesser one end of measuring cylinder diameter is lower port.
Magnifying glass is connected at the index line of the side wall of sighting tube.
One syringe is 10ML, another syringe is 5ML.
Two syringes are 10ML.
The beneficial effects of the utility model are:
A kind of device for rat toes swelling measurement of the utility model, using the measuring cylinder being relatively large in diameter, by setting
The sighting tube being connected to measuring cylinder is set, magnifying glass is equipped at the index line of sighting tube, passing through during experiment can be accurate
Control liquid level is overlapped with index line on sighting tube, so that measurement result is accurate；
A kind of device for rat toes swelling measurement of the utility model, is measured by the way that two syringes are arranged,
The result that front and back measures twice can all be preserved；
A kind of device for rat toes swelling measurement of the utility model, by the way that two syringes of different sizes are arranged
It measures, suitable syringe can be used according to the size of rat toes, using simple.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the device for rat toes swelling measurement of the utility model.
In figure, 1. measuring cylinders, 2. sighting tubes, 3. connection hoses, 4. threeways, 5. syringes, 6. index lines, 7. magnifying glasses.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of device for rat toes swelling measurement, as shown in Figure 1, including the measurement funnel-shaped being vertically arranged
Cylinder 1, the lesser one end of 1 diameter of measuring cylinder be lower port, measuring cylinder 1 on the side wall at lower port with L-shaped sighting tube 2
One end connection, the other end of sighting tube 2 is not less than the upper port of measuring cylinder 1, is carved with index line 6 on the outer wall of sighting tube 2, refers to
Timberline 6 is close to one end that sighting tube 2 is not connected with measuring cylinder 1, and index line 6 is not higher than the upper port of measuring cylinder 1, sighting tube 2
Side wall on be provided at index line 6 and be connected with magnifying glass 7；The lower port of measuring cylinder 1 and the one end for connecting hose 3 connect soft
The other end of pipe 3 is connect with an interface of threeway 4, other two interface of threeway 4 passes through hose respectively and is connected with syringe
5；Wherein, a syringe 5 is 10ML, another syringe 5 is 5ML；Either two syringes 5 are 10ML.
A kind of observation of the device for rat toes swelling measurement being connected to by setting with measuring cylinder of the utility model
Pipe is overlapped by observation liquid level with index line on sighting tube during experiment, because the diameter of sighting tube is smaller, so that estimating
Liquid level and index line registration it is high, measurement result is accurate；Meanwhile magnifying glass is equipped at the index line of sighting tube, liquid level with
The more accurate height that index line is overlapped, measurement result are more accurate；It is measured by the way that two syringes are arranged, it can be by front and back
Measurement result twice, which all preserves, conveniently to be compared；It is measured by the way that two syringes of different sizes are arranged, energy
It is enough that suitable syringe is used according to the size of rat toes, so that the volume in the syringe read out is more accurate, simultaneously
