An esophageal lead electrode fixing device

Abstract

The invention relates to a fixing device for an esophageal lead electrode. A sleeve body is of an annular structure. A first connection piece, a second connection piece, a third connection piece and a fourth connection piece are annular and are uniformly distributed below the sleeve body and provided with threads corresponding to one another. Fastening nuts are arranged outside the first connection piece, the second connection piece, the third connection piece and the fourth connection piece in a sleeved mode. The widths of the upper portion of the first connection piece, the upper portion of the second connection piece, the upper portion of the third connection piece and the upper portion of the fourth connection piece are not smaller than the widths of the lower portion of the first connection piece, the lower portion of the second connection piece, the lower portion of the third connection piece and the lower portion of the fourth connection piece. The fastening nuts are arranged outside the first connection piece, the second connection piece, the third connection piece and the fourth connection piece from bottom to top in a sleeved mode. The fixing device is simple in structure, low in cost, suitable for mass production and good in social benefit and economic benefit.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a fixing device for medical devices, in particular to a fixing device for esophageal lead electrodes. Background technique [0002] In 1906, Cremer created the esophageal lead electrocardiogram, which uses electrodes placed in the esophagus to indirectly pace the left atrium to trace the electrocardiogram. Due to the close relationship between the esophagus and the heart anatomy, the atrial wave amplitude is high. At the same time, it is non-invasive, simple and convenient. Easy to operate and cheap, it has become one of the indispensable non-invasive diagnostic methods for the diagnosis of arrhythmia. The esophageal lead electrocardiogram sends the esophageal electrode into the left atrium adjacent to the esophagus through the mouth or nasal cavity. Whether the esophageal lead electrode is positioned accurately after intubation is one of the important links for a smooth inspection...

AI Technical Summary

Problems solved by technology

The esophageal lead electrocardiogram sends the esophageal electrode into the left atrium adjacent to the esophagus through the mouth or nasal cavity. Whether the esophageal lead electrode is positioned accurately after intubation is one of the important links for a smooth inspection. After accurate positioning, the electrode cannot go up and down in the esophagus Movement (breathing with the human body, and at the same time, the inspection process will cause discomfort such as local burning sensation to the human body, and the human body is not easy to cooperate) affects the recording effect. In the past, adhesive plasters were used for fixed electrodes (intubation from the nasal cavity) or clenching between two adjacent teeth (from the oral cavity) Intubation), the fixing methods of different intubation routes will damage or bite off the insulation layer of the electrode part in contact with the adhesive plaster and teeth, which will easily cause inaccurate diagnostic results and may cause misdiagnosis
