Abstract
The utility model belongs to medical appliance supplies, in particular to a precordial electrocardiographic lead electrode, which consists of a hollow rubber ball, a gas vent, a place for connecting an electrocardiographic lead wire, a metal spring, a bowl-shaped electrode metal part, a metal electrode slice and rubber edges. The opening diameter of the bowl-shaped electrode metal part is 2.83cm, the opening area of the bowl-shaped electrode metal part is 2 times larger than that of a common precordial lead electrode, and the adsorption of the bowl-shaped electrode metal part is 2 times larger than that of the common precordial lead electrode; and simultaneously, the edge of the bowl-shaped electrode metal part consists of softer rubber edges and can generate certain deformation along with the shape of the chest wall so as to be close to the skin, thereby preventing from leaking air and falling off. A certain amount of gas is exhausted through the gas vent by pressing the hollow rubber ball, and then the bowl-shaped electrode metal part is placed on the chest wall; after the hollow rubber ball is released, the negative pressure is generated on the skin, so that the bowl-shaped electrode metal part is adsorbed on the skin, and simultaneously, the circular metal electrode slice in the middle is adsorbed on the skin in the middle of the bowl-shaped electrode metal part under the action of elasticity of the spring; and electrocardiographic signals are conducted to the place for connecting the electrocardiographic lead wire through the metal spring and the back of the bowl-shaped electrode metal part and are conducted to an electrocardiographic lead wire through the place for connecting electrocardiographic lead wire to be sent to an electrocardiograph.
Description
Technical field this utility model belongs to the medical apparatus and instruments articles for use, a kind of specifically anterior electrocardiographic lead electrode.
It is to be made of metal a kind of bowl structure that background technology is generally used the anterior electrocardiographic lead electrode at present, because metal electrode is hard, can not be adjacent to surface with the warpage of contact surface, and it is low with the little absorption affinity of skin contact, so run into the few patient of thin and weak subcutaneous fat, difficulty is adsorbed in skin, and easily comes off.
The summary of the invention the purpose of this utility model overcomes above deficiency exactly, provide a kind of can be with the contact surface warpage, and the precordial leads electrode stronger with the big absorption affinity of contact skin area.
The technical solution of the utility model is: this utility model is by the hollow rubber ball, and gas port connects electrocardiogram lead line place, metal spring, and bowl-shape electrode metal portion, metal electrode film, rubber edges is formed.The opening diameter that it is characterized in that bowl-shape electrode metal portion is 2.83cm (generally using the anterior electrocardiographic lead electrode diameter to be 2cm at present), the aperture area of bowl-shape like this electrode metal portion is 2 times of common precordial leads electrode opening area, absorption affinity is twice, the while edge of bowl-shape electrode metal portion is made up of more softish rubber edges, can produce certain deformation with the thoracic wall shape, thereby better be adjacent to skin, prevent gas leakage.In the middle of the bowl-shape electrode metal portion is the elastic reaction of a circular metal electrode slice by metal spring, be attached on the intermediary skin of bowl-shape electrode metal portion, rear portion by metal spring and bowl-shape electrode metal portion is transmitted to electrocardiosignal and is connected electrocardiogram lead line place, by connecting electrocardiogram lead line place conduction electrocardiosignal, send into electrocardiograph to the electrocardiogram lead line.
This utility model is owing to adopt said structure, the aperture area that it is characterized in that bowl-shape electrode metal portion is 2 times of common precordial leads electrode opening area, absorption affinity is twice, the while edge of bowl-shape electrode metal portion is made up of more softish rubber edges, can produce certain deformation with the thoracic wall shape, thereby better be adjacent to skin, prevent gas leakage, be adsorbed in skin thereby overcome the electrode difficulty, caducous shortcoming.
Description of drawings is a structural representation of the present utility model
1 hollow rubber ball, 2 gas ports 3 connect the electrocardiogram lead line place bowl-shape electrode metal of 4 metal springs 5 portion 6 metal electrode films, 7 rubber edges
Specific embodiment this utility model is by hollow rubber ball (1), and gas port (2) connects electrocardiogram lead line place (3), metal spring (4), and bowl-shape electrode metal portion (5), metal electrode film (6), rubber edges (7) is formed.The opening diameter of bowl-shape electrode metal portion (5) is 2.83cm (generally using the anterior electrocardiographic lead electrode diameter to be 2cm at present), the aperture area of bowl-shape like this electrode metal portion (5) is 2 times of common precordial leads electrode opening area, and the edge of bowl-shape electrode metal portion (5) is made up of more softish rubber edges (7).Press hollow rubber ball (1) during use earlier, discharge a certain amount of gas by gas port (2), then bowl-shape electrode metal portion (5) is placed on the thoracic wall, unclamp hollow rubber ball (1), produce negative pressure at the skin place, be adsorbed on the skin, intermediary circular metal electrode slice (6) is by the elastic reaction of spring (4) simultaneously, be attached on the intermediary skin of bowl-shape electrode metal portion (5), rear portion by metal spring (4) and bowl-shape electrode metal portion (5) is transmitted to electrocardiosignal and is connected electrocardiogram lead line place (3), by connecting electrocardiogram lead line place (3) conduction electrocardiosignal, send into electrocardiograph to the electrocardiogram lead line.Because the open area ratio ordinary electrode is twice, so absorption affinity obviously increases,, be closely attached on skin so can produce necessarily be out of shape with the thoracic wall shape because bowl-shape electrode metal portion edge is softer, prevent to leak gas, thereby prevent to come off.
Claims (2)
1. anterior electrocardiographic lead electrode, by hollow rubber ball (1), gas port (2), connect electrocardiogram lead line place (3), metal spring (4), bowl-shape electrode metal portion (5), metal electrode film (6), rubber edges (7) is formed, and it is characterized in that: the opening diameter of described bowl-shape electrode metal portion (5) is 2.83cm, and aperture area is 2 times of common precordial leads electrode opening area.
2. according to anterior electrocardiographic lead electrode according to claim 1, it is characterized in that: bowl-shape electrode metal portion (5) edge by making than soft rubber edge (7), can produce certain distortion with appended thoracic wall shape.
