Fig. 1 is the experimental facilities connection layout of existing " premature beat and compensatory pause " experiment, as shown in Figure 1, gets after Bufo siccus destroys brain and spinal cord, and back of the body position is fixed on the frog board, exposes heart.Clamp the frog apex of the heart with the frog heart clip of anchor line (string), the other end of line is connected with tonotransducer, simultaneously, frog heart stimulating electrode is fixed on the Bufo siccus heart surface, and its positive and negative electrode is closely contacted with ventricle surfaces.By regulating amplitude, frequency and the width etc. of the current impulse that electrostimulator sends, giving the frog heart respectively in the different time of the systole of ventricle and relaxing period stimulates.The tension signal that tonotransducer produces when frog heart beating is moved converts the signal of telecommunication to and exports BL-410 bio signal acquisition system to, BL-410 bio signal acquisition system record heartbeat curve, thereby the experimental result of obtaining.
In above-mentioned experiment, frog heart stimulating electrode fixedly be the whether successful key of this experiment, if the tightness degree that frog heart stimulating electrode contacts with ventricle surfaces is not enough, then can owing to ventricle easypro contract motion touch when producing the time from phenomenon, can not load stable electrical stimulation signal, experiment can't be carried out smoothly; If contact is too tight, then may influence cardiac muscle and normally beat, hinder the accurate recording of heartbeat curve.And existing frog heart stimulating electrode generally adopts the clip of pair of metal to make, and is clipped in the frog in the heart, perhaps directly adopts a pair of nuditing wire, and use medical proof fabric etc. is bonded in the frog in the heart, is easy to occur the problems referred to above.In addition, stimulating electrode also can puncture heart or because of strong the beating of the frog heart comes off suddenly, cause experiment to be interrupted sometimes, makes the success rate of " premature beat and compensatory pause " experiment be difficult to guarantee.
The utility model content
This utility model embodiment provides a kind of frog heart stimulating electrode, is not easy to come off in the heart from the frog, can improve the success rate of " premature beat and compensatory pause " experiment.
For achieving the above object, the technical solution of the utility model specifically is achieved in that
A kind of frog heart stimulating electrode comprises positive pole and negative pole, and described positive pole is a metallic plate, is used to contact frog body, connects electrostimulator output cathode end simultaneously; Described negative pole comprises frog heart clip, is used to contact the frog heart, connects electrostimulator output negative pole end and tonotransducer simultaneously.
As seen from the above technical solutions, this frog heart stimulating electrode of the present utility model realizes that the frog heart stimulates and frog Herzschlag record dual-use material.With the negative pole of frog heart clip as frog heart stimulating electrode, make frog heart stimulating electrode both can be used as stimulating electrode, can be used as the connector of the tonotransducer and the frog heart again, conduction heartbeat and the binomial function that stimulates the frog heart are united two into one, reduced and to be fastened on frog device in the heart, reduce electrode and connect inappropriate probability, thereby solve the problem that frog heart stimulating electrode comes off easily, improved the success rate of experiment.By with the positive pole of metallic plate as frog heart stimulating electrode, thereby need not to contact under the condition of the frog heart, conductive characteristic by frog body itself, stimulating current is conducted to the frog in the heart, further reduced and to be fastened on frog device in the heart, connect inappropriate probability thereby further reduce electrode, improved the success rate of experiment.
