Abstract
The utility model discloses a mapping electrode component which is characterized by comprising an external sleeve, a copper wire, a three-way connector, a flexible rubber plug, a hose and an injector joint, wherein the rear end of the external sleeve is connected with the front end of the three-way connector, a hole at the rear end of the three-way connector is internally provided with the flexible rubber plug, the copper wire penetrates through the rear end of the flexible rubber plug and the external sleeve and then extends out of the front end of the external sleeve, and a gap is reserved between the copper wire and the external sleeve; and a third end of the three-way connector is a medicine port which is connected with one end of the injector joint by the hose. The mapping electrode component has the advantages of avoiding thoracotomy, having little auxiliary damage, being capable of establishing a chronic model, replacing a method of jugular vein intubation tube to estimate the function of atrionector, and enabling the operation to be simple, convenient and easy, the locating to be accurate and the operation to be simple and convenient.
Description
Technical field
This utility model relates to a kind of mapping electrode assemblie, is mainly used in zooperal electrophysiologic study, need not open breast, reduces secondary damage.
Background technology
The conventional construction model method is for opening behind the breast with formaldehyde soak right atrium, perhaps opens ligation coronary artery behind the breast.Above-mentioned two kinds of methods all easily because of misoperation cause wide in tremulous pulse and injury of pleura, cause the laboratory animal massive hemorrhage and (or) hemopneumothorax, cause animal pattern death; The method of tradition assessment sinus node function is to insert electrode catheter to right atrium through right external jugular vein, measures the value of SNRT, SACT.
Summary of the invention
The purpose of this utility model just provides a kind of mapping electrode assemblie, with causing easily of solving that prior art exists when carrying out zoopery wide in tremulous pulse and injury of pleura, cause the laboratory animal massive hemorrhage and (or) hemopneumothorax, cause the problem of animal pattern death.
The technical solution of the utility model is: comprise trocar sheath, copper wire, three way cock, flexible glue plug, flexible pipe and injector to inject interface, the rear end of trocar sheath is connected with three way cock's front end, in the hole of this three way cock's rear end, be provided with the flexible glue plug, copper wire passes the rear end of this flexible glue plug and trocar sheath and stretches out from the front end of this trocar sheath, leaves the gap between this copper wire and trocar sheath; This three way cock's the 3rd end is the medicine interface, and this medicine interface is connected with an end of injector to inject interface by flexible pipe.
Described trocar sheath, three way cock and injector to inject interface all adopt medical plastic to make, and the flexible glue plug adopts medical silica-gel to make.
The utility model has the advantages that:
1, exempt from out breast, secondary damage is minimum, can set up chronic model;
2, replace the method assessment sinus node function of jugular vein intubate, make easy to operation;
3, accurate positioning;
4, easy and simple to handle.

Each parts effect of this utility model is:
Trocar sheath 1 has the effect of insulation and injectable drug.
Three way cock 3 realizes the junction of electrode (copper wire 2) and drug channel.
Flexible glue plug 4 has the medicinal liquid of prevention outflow effect.
This utility model using method is:
1, set up the operational approach of disease hole model (sick sinus syndrome model):
A. the front end with trocar sheath 1 and copper wire 2 directly thrusts the rat thoracic cavity, makes the preceding end in contact exterior heart surface of copper wire 2.
B. the rear end of copper wire 2 and electrocardiograph V
1The connection of leading, mapping visceral pericardium figure.When figure met the sinuatrial node position, by injector to inject interface 7 injectable drugs, medicine entered in the animal body through the gap between flexible pipe 6, three way cock 3 and copper wire 2 and the trocar sheath 1 with syringe, and disease hole model is set up in corrosion antrum interface.
2, measure the operational approach of sinus node function:
A. the front end with trocar sheath 1 and copper wire 2 directly thrusts the rat thoracic cavity, makes the preceding end in contact exterior heart surface of copper wire 2.
B. the rear end of copper wire 2 and electrocardiograph V
1The connection of leading, mapping visceral pericardium figure.
C. when meeting the sinuatrial node position, figure removes electrocardiograph V
1Link of leading and connection pulse generator carry out sinus node recovery time (SNRT), the measurement of sinoatrial conduction time (SACT), the function of assessment sinuatrial node.
