Description
Technical field
The utility model belongs to experiment apparatus technical field, and in particular to a kind of isolated frog heart perfusion success rate of improving
Teaching frog heart cannula.
Background technology
From the beginning is founded after more than 100 years, the current experiment has turned into physiology, pharmacology, pathology to isolated frog heart perfusion experiment
The method of the observation cardiomotility commonly used Deng Functional Experiment, is widely used in biology and medical teaching and scientific research.Knot
Close Functional Experiment Teaching practice in recent years and find that the intubation technique difficulty that the experiment is related to is larger, and success rate is not high.
It has been proposed that some improved measures：The toad of selection proper body weight (being more than 90g), its arteries is thicker, profit
In intubation；Ventricle is slightly lifted during aorta sinistra intubation, whole ventricle is respectively positioned on the front of intubation, be easy to intubation；Vein
Ligature respectively, it is to avoid prick venous sinus by mistake；Change the blood vessel of intubation, be changed to aorta dextra intubation；Heparin is added to keep away in ringer solution
Exempt from the generation of blood coagulation phenomenon.
Successful intubation is set to increase by above-mentioned measure, but still it is not ideal enough.Main cause：Existing frog heart cannula
Glassware is, is easily broken, special intubation front end breakage rate is up to more than 50%, the success rate of extreme influence experiment；It is existing
There is frog heart cannula and isolated frog heart is hung using a step, and glass material is excessively smooth, lanyard is easily skidded off from step, from
The body frog heart is separated with intubation and causes experiment unsuccessful.
The content of the invention
In view of this, the purpose of this utility model is to provide a kind of frog heart cannula, by changing material and setting up fixation
Structure, greatly improves successful intubation, not high to solve the problems, such as prior art success rate.
To reach above-mentioned purpose, the utility model provides following technical scheme：
A kind of frog heart cannula, the intubation is one section of body being made of plastic material, and the body includes diameter phase
Relatively small to big liquid storage section and diameter goes out liquid section, and frog heart suspended and fixed device, the frog heart are provided with the liquid storage section
Suspended and fixed device includes suspension arm, compact heap and connecting rod, and the suspension arm is stretched out setting, institute by the outer wall of liquid storage section
Connecting rod one end is stated by the rotatable distal end for being fixed on suspension arm of hinged structure, the other end is fixed with compact heap, it is described go out liquid
The front end of section is provided with one and imports cone, the front end rounding off for importing cone.
Further, the frog heart suspended and fixed device is provided with four and is distributed on the outer of the liquid storage section sustained height altogether
On the face of cylinder.
Further, the frog heart suspended and fixed device also includes the operation handle being arranged on the compact heap.
Further, it is additionally provided with liquid scale in the liquid storage section.
The beneficial effects of the utility model are：
The utility model is improved to plastics by by the material of intubation by glass, it is to avoid damaged generation, improves intubation
Durability, and then improve experiment success rate；And the frog heart is fixedly secured in intubation by frog heart suspended and fixed device, keep away
Relative movement is between the two exempted from, has reduced unsuccessful caused by both are separated from each other；In addition, will can also be inserted by importing cone
Manage in smooth Access artery pipe, improve success rate, while avoiding the damage to artery by rounding off in the front end for importing cone.
Other advantages of the present utility model, target and feature will be explained in the following description to a certain extent
State, and to a certain extent, based on being will be apparent to those skilled in the art to investigating hereafter, or
Person can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be said by following
Bright book is realized and obtained.
Brief description of the drawings
In order that the purpose of this utility model, technical scheme and beneficial effect are clearer, the utility model provides as follows
