Problems solved by technology

[0005] Temporary pacemakers are widely used in cardiac surgery. For example, for patients with atrioventricular block or severe bradycardia after surgical repair of congenital heart disease, temporary pacemakers are used temporarily. The device is usually placed in the body for 7-10 days. After the pacing lead is placed on the surface of the heart, the pacing lead should be passed through the human tissue, from the pericardial cavity to the outside of the skin, and connected to the pacemaker outside the body. After the patient recovers smoothly Finally, the pacing lead needs to be dealt with. Forcibly pulling out the pacing lead will easily damage the myocardial tissue, causing bleeding and cardiac tamponade; if the lead is not pulled out but the part exposed to the skin is cut off, the long-term retention of the lead in the body will cause infection and irritate the tissue severely. hyperplasia

Embodiment 1

[0027] The invention provides a photoelectric pacemaker assembly, including a host and a photoelectric pacemaker, the host includes a light source generating module, the light source generating module includes sequentially connected light emitters and light source irradiation heads, and the light emitters are full-spectrum wavelength monochromatic The light source, the light source irradiation head illuminates the light to the photoelectric pacemaker. The light source generating module is used to provide light for the photoelectric pacemaker.

[0028] The photoelectric pacemaker is composed of a photoelectric conversion sheet and a fixing belt. The photoelectric conversion sheet is sutured on the surface of the ventricle or atrium through the fixing belts on both sides. The photoelectric conversion sheet converts the light irradiated by the light source head through the patient's body tissue into The power supply generates pulsed current to stimulate the contraction of cardiom...

Embodiment 2

[0034] The invention provides another photoelectric pacemaker assembly, which can measure the cardiac electrical activity of the patient while the pacemaker is working. Integrate the ECG monitoring module in the host. The ECG monitoring module is sequentially provided with an input circuit, a lead selection, an amplifying circuit, a pen drive and a paper feeding device for detecting the patient's ECG activity.

[0035] There are several electrode pads on the shading vest for detecting body surface ECG, and the electrode pads are respectively set at corresponding positions on the patient's body, among which: V1: the fourth intercostal space on the right border of the sternum; V2: the fourth intercostal space on the left border of the sternum; V3 : midpoint of the line connecting V2 and V4; V4: intersection of the left midclavicular line and the fifth intercostal space; V5: left anterior axillary line at the same level as V4; V6: left midaxillary line at the same level as V4; V7...

Embodiment 3

[0037] There is also a transformer between the power supply and the light emitter, which is used to change the intensity of the light source; an optical filter and a frequency modulator are also arranged between the light emitter and the light source head, and the optical filter is used to filter out light of different wavelengths to achieve wavelength adjustment; there is also a frequency regulator, which adjusts the frequency of the light output.

[0038]The frequency adjuster is provided with a driving motor, a motor gear and a number of shading film wheels connected in sequence. The driving motor rotates the motor gear to make the shading film wheel on the gear rotate, and the light is projected through the gap between the shading films. Speed ​​to adjust the frequency of raycasts.

[0039] The optical filter is equipped with a variety of filter lenses, which are placed on the light path by changing different lenses to filter out light in different wavelength bands to achi...

Abstract

The invention provides a photoelectric pacemaker assembly, and the assembly comprises a main unit, a shading waistcoat, and a photoelectric pacemaker. The photoelectric pacemaker is disposed on the surface of a heart, and the main unit provides a light source which irradiates a part, corresponding to the photoelectric pacemaker, of the body surface of a patient. The light passes through the tissues of the body to reach the photoelectric pacemaker, and the photoelectric pacemaker performs photoelectric reaction to generate a pulse current for stimulating the cardiac muscle cells to shrink so asto maintain the blood pumping function of the heart.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a photoelectric pacemaker assembly. Background technique [0002] Artificial cardiac pacing refers to the use of specific pulse currents to stimulate myocardial cells, depolarize the myocardium, cause cardiac contraction and maintain blood pumping function. Cardiac pacing is an effective treatment for symptomatic bradyarrhythmias, as well as for refractory tachyarrhythmias that are refractory to medication or complex arrhythmias that are contradictory to drug therapy. In addition, cardiac pacing is used in the diagnosis of heart disease, cardiac electrophysiological studies, anesthesia, surgery and cardiac protection for invasive cardiac examinations. [0003] Emergency cardiac pacing often uses transvenous endocardial pacing or noninvasive external cardiac pacing. In addition, there are transesophageal pacing, transthoracic myocardial pacing and epicardial pacing. ...
