Abstract
The utility model relates to a floating double-electrode pacing catheter, which is characterized by comprising a main catheter, an air-filled port, a combination handle, an air bag, a near-end electrode and a far-end electrode, wherein the air-filled port, the near-end electrode and the far-end electrode are connected with the main catheter via the combination handle; the front end of the main catheter is provided with an air-filled hole; the air-filled hole is covered by the air bag; and the front side and the back side of the air bag are provided with electrode joints. According to the floating double-electrode pacing catheter, effective pacing can be obtained with no need of x-ray fluoroscopy, implantation is quick, the success rate is high, and the floating double-electrode pacing catheter is particularly applied to temporary cardiac pacing in case of emergency.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of floating bipolar pacing conduit for temporary heart pace-making.
Background technology
Conventional ordinary electrode conduit, through vein endocardial pacing, need operate under X-ray examination, just sure location successfully, and required supporting apparatus and equipment complexity, have relatively high expectations to medical personnel's operant level, and implantation speed is slower.
Utility model content
For the deficiencies in the prior art, this utility model provides one not need X-ray examination, can obtain effective pace-making, and implants rapidly the floating bipolar pacing conduit that success rate is high.
For completing above-mentioned task, the technology of the present invention solution is achieved in that a kind of floating bipolar pacing conduit, it is characterized in that, comprises main catheter body, inflation port, in conjunction with handle, air bag, proximal electrode and remote electrode; Inflation port, proximal electrode and remote electrode are by being connected with main catheter body in conjunction with handle, and main catheter body front end is provided with air-filled pore, and air-filled pore wraps up with air bag, and before and after air bag, both sides are provided with electrode contact; Wherein remote electrode joint is positioned at main catheter body top, and proximal electrode joint is positioned on air bag rear side main catheter body.
This utility model is for designing through vein temporary heart pace-making, be used in conjunction with and pace-making electricity irritation can be delivered to heart with pulse generator, can also be by the electrical signal transfer of heart to recording equipment, its beneficial effect is, the both sides of catheter proximal end air bag have increased the metal electrode of top and ring-type, light and thin floating electrodes conduit can rely on the floating force after front end airbag aeration be floated to right atrium from peripheral vein, and strides across Tricuspid valve and float into right ventricle, carries out right ventricle cardiac temporary pacing; Its equipment is simple, and implantation speed is fast, and the time that the other Pacing of bed of floating bipolar pacing conduit need be used is only 3-10 min; With other method comparison, the cardiac temporary pacing success rate of floating bipolar pacing conduit is high, and simple to operate easy to learn, maintains effective pace-making and can reach 1-2 week after implantation.

Fig. 2 is the structure enlarged drawing of catheter proximal end part in Fig. 1;
In figure, 1, inflation port, 2, proximal electrode, 3, remote electrode, 4, in conjunction with handle, 5, main catheter body, 6, proximal electrode joint, 7, air-filled pore, 8, air bag, 9, remote electrode joint.
The specific embodiment
A kind of floating bipolar pacing conduit, as shown in Figure 1 and Figure 2, is characterized in that, comprises main catheter body 5, inflation port 1, in conjunction with handle 4, air bag 8, proximal electrode 2 and remote electrode 3; Inflation port 1, proximal electrode 2 and remote electrode 3 are by being connected with main catheter body 5 in conjunction with handle 4, and main catheter body 5 front ends are provided with air-filled pore 7, and air-filled pore 7 wraps up with air bag 8, and air bag 8 both sides, front and back are provided with electrode contact; Wherein remote electrode joint 9 is positioned at main catheter body top, and proximal electrode joint 6 is positioned on air bag rear side main catheter body.
The method of application this utility model pace-making is: this utility model afterbody is connected with the syringe of outfit, whether vitro examination air bag leaks gas, then in vitro the afterbody positive and negative connector of floating bipolar pacing conduit and temporary pacemaker both positive and negative polarity are joined, and open pacemaker, adjust pace-making perceptual sensitivity to 1-3mV, pace-making voltage 5V, pacing frequency is set as higher than 20 left and right of self heart rate, send into floating bipolar pacing conduit from sheath pipe, when striding across after sheath pipe, air bag top (enters the about 15cm of electrode catheter), in air bag, inflate 1.0ml by assistant, under lasting body surface electrocardiogram monitoring, patient continues inwardly to send into floating bipolar pacing conduit, in the time there is ventricular pacemaking, exit immediately, and continuation pushes forward conduit, lead and be the wide QRS ventricular pacemaking waveform under main wave direction to II, prompting conduit is delivered to apex, observed and recorded: measure the length to apex of the heart pace-making rear tube top to point of puncture through different approaches by supravasal scale, record is from venipuncture to ventricular pacemaking required time.
Claims (2)
1. a floating bipolar pacing conduit, is characterized in that, comprises main catheter body, inflation port, in conjunction with handle, air bag, proximal electrode and remote electrode; Inflation port, proximal electrode and remote electrode are by being connected with main catheter body in conjunction with handle, and main catheter body front end is provided with air-filled pore, and air-filled pore wraps up with air bag, and before and after air bag, both sides are provided with electrode contact.
2. the floating bipolar pacing conduit of one according to claim 1, is characterized in that, before and after air bag, in the electrode contact of both sides, remote electrode joint is positioned at main catheter body top.
