Pressure bandaging bandage used after cardiac pacemaker implantation

Technical Field

The invention relates to the field of postoperative recovery tools, in particular to a compression bandaging bandage used after a cardiac pacemaker implantation operation.

Background

The cardiac pacemaker implantation is a treatment method of artificially implanting a cardiac pacemaker, stimulating the heart by pulse current with specific frequency through a lead and an electrode to replace a pacing point of the heart to drive the heart to beat, and is a safe and effective method for treating irreversible cardiac pacing conduction dysfunction, in particular to treating severe chronic arrhythmia. The artificial cardiac pacing system mainly comprises two parts: the pulse generator sends pulse current with a certain frequency at fixed time, and the pulse current is transmitted to the myocardium (atrium or ventricle) contacted with the electrode through the lead and the electrode, so that local cardiomyocytes are excited by external electric stimulation and conducted to the surrounding myocardium through intercellular gap connection or intercalated disc connection, and the whole atrium or ventricle is excited and then generates contraction activity. It is emphasized that the heart muscle must have excitatory, conductive and contractile functions, and that cardiac pacing can play its role.

The cardiac pacemaker implantation postoperative resumes and generally all need to pressurize through the bandage and wrap, oppression time is too long, the patient can feel strong uncomfortable and feel, consequently can often oppress after a period patient and can be locking for a moment, oppress and locking in-process repeatedly, the skew appears easily in the oppression position, thereby can influence the oppression effect, and then influence patient's recovery, and simultaneously, in the in-service use process, different circumstances need different oppression intensity, at present can not be fine to bandage oppression intensity adjust, influence whole recovery effect.
