Abstract
The utility model relates to a biological teaching equipment field discloses a frog heart presss from both sides, included frog heart presss from both sides coil and lag subassembly, to the myocardial damage of the frog, the lag subassembly can not polluted with liquid by the experiment by effectual protection frog heart presss from both sides coil simultaneously in the time of can effectively reducing student behaviour and do through nested lag subassembly on the frog heart presss from both sides coil, through set up the electrode coil on the frog heart presss from both sides coil, and the use that has made things convenient for the electro photoluminescence to test, the lag subassembly adoption thermoplastic elastomer manufacturing of use can the effectual life who prolongs frog heart presss from both sides.
Description
Technical field
The utility model relates to bioconversion medium clothing arts, particularly a kind of frog heart folder.
Background technology
Isolated frog heart (losing the frog heart of innervation) is remained in suitable environment, still contraction and the diastole of rhythmicity can be kept within the regular hour, and the normal rhythmic activity of frog heart needs a suitable physicochemical environment, isolated frog heart is dirty is also like this. By some composition in change frog heart perfusate in physiological experimental class, observe it to the impact of frog cardiomotility. The autorhymicity of myocardial cell, excitability, conductivity and shrinkability, all relevant with the various ions such as sodium, potassium and calcium and humoral factor, external source gives the activity that norepinephrine, suprarenin or vagusstoff can affect heart.
The frog heart folder main raw used in current each higher medical universities and colleges Physiology Experiment class is made of iron, and the direct quick-fried leakage irony of two ends end points of folder frog heart is relatively more sharp-pointed, and very hard. In upper laboratory process, student often grasps the size of not good sandwich dirty position and folder frog heart area, often causes the myocardial damage of big area, has both wasted the heart of a lot of frog, also have impact on the accuracy of experimental result simultaneously. The iron frog heart folder that Xian Geyi class institution of higher learning physiological experimental class is used, although the funds of saving, Reusability, but very not science.
Summary of the invention
The purpose of this utility model is to provide a kind of frog heart folder, to meet daily biological experiment operating demand.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model discloses a kind of frog heart folder, include frog heart clamp circle and protecting jacket assembly, frog heart clamp circle is bent into the arc of opening, and in frog heart clamp circle centre portion around circular coil, protecting jacket assembly includes ring sleeve and spherical lasso, ring sleeve is nested on frog heart clamp circle, and spherical lasso is nested in the two ends of frog heart clamp circle.
Preferably, also comprising electrode coil, electrode coil is welded to each other around the circular coil become with frog heart clamp circle centre portion.
Preferably, frog heart clamp circle adopts the preparation of medical stainless steel material, and protecting jacket assembly adopts thermoplastic elastomer preparation.
The utility model has following useful effect:
1. the utility model can effectively be reduced to the damage of the frog cardiac muscle when student behaviour does by nested protecting jacket assembly on frog heart clamp circle, and protecting jacket assembly can effectively protect frog heart clamp circle not polluted by experiment liquid simultaneously.
2., by being provided with electrode coil on frog heart clamp circle, facilitate the use of electricity irritation experiment, it may also be useful to protecting jacket assembly adopt thermoplastic elastomer, it is possible to the effective work-ing life extending frog heart folder.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Main element numbers illustrates:
1: frog heart clamp circle, 2: circular coil, 3: electrode coil, 4: ring sleeve, 5: spherical lasso
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.
As shown in Figure 1, the utility model discloses a kind of frog heart folder, include frog heart clamp circle 1 and protecting jacket assembly, protecting jacket assembly includes ring sleeve 4 and spherical lasso 5.
Frog heart clamp circle 1 is bent into the arc of opening, and in the middle portion of frog heart clamp circle 1 around circular coil 3, electrode coil 3 is welded to each other around the circular coil 2 become with the middle portion of frog heart clamp circle 1, ring sleeve 4 is nested on frog heart clamp circle 1, spherical lasso 5 is nested in the two ends of frog heart clamp circle 1, wherein, frog heart clamp circle 1 adopts medical stainless steel material to prepare, and protecting jacket assembly adopts thermoplastic elastomer preparation.
The above; it is only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; any it is familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
