    • An electrolyte (70) for use in a single-use biomedical electrode assembly (A, B, C, D) designed for receiving body-generated electrical signals at a patient's skin surface includes: Component Range (%) Skin penetration agent 10-25  Thickener 0-10 Alkali metal or alkaline earth 1-13 metal chloride Alkali metal or alkali earth 1-13 metal nitrate Surfactant 0.001-5    Soluble silver salt, as silver   0-0.01 Buffer 0-10 Water Q.S. The skin penetration agent improves penetration of the outer, dead skin layers by the electrolyte, thereby improving pickup of minute electrical signals generated within the patient's body. A preferred skin penetration agent includes sodium 2-pyrrolidone-5 carboxylate at a concentration of 15-20% by weight of the electrolyte composition. Penetration of the composition is augmented by the hydraulic force of a snap-down housing (24) and by a skin adhesive (94) for effective sealing and adherence to the patient's skin.
    • 用于单用途生物医学电极组件(A,B,C,D)中设计用于在患者皮肤表面接收身体产生的电信号的电解质(70)包括:皮肤穿透剂改善外部死亡 皮肤层由电解质,从而改善在患者体内产生的微小电信号的拾取。 优选的皮肤渗透剂包括浓度为电解质组合物重量的15-20%的2-吡咯烷酮-5-羧酸钠。 组合物的渗透通过坠落壳体(24)和皮肤粘合剂(94)的液压力增强,以有效地密封和粘附到患者的皮肤上。
