Abstract
The electrode block for cardiograph of the present invention is used repeatedly and the conductive liquid is compounded with alcohol and NaCl. Unlike available technology, which uses conductive paste as conducting medium and uses once-used adhesive electrode block, the present invention is simple and can result in excellent display effect.
Description
The invention belongs in the medical diagnosis apparatus heart bio electricity in the human body is received and the technical field of conducting.
The human heart cell has irritability, self-disciplining and conductivity, can automatically there be rhythm and pace of moving things ground to produce bio electricity and in heart, propagates in order along the specific conduction system, human body itself is a good conductor to bio electricity, the exciting Weak current that is produced of cardiac muscle can be transmitted to body surface through bodily tissue, make the different parts of body surface produce different current potentials, if place 2 electrodes at body surface, be connected to the two ends of electrocardiograph respectively with the line that leads, it will be according to the time sequencing of heart excitement, the potential difference of body surface point-to-point transmission is noted, formed successive curve, i.e. an electrocardiogram.Affiliated electrocardio device all adopts disposable heart electrode piece on the existing ultrasonic cardiograph, because its material is fine silver or copper silver-plated, and the cost height, and abandon in a large number and cause environmental pollution.The disposable heart electrode piece of hewlette-packard production has adopted foam-rubber cushion, but still by electrode paste as conducting medium, can not reuse, still there is cost problem high and that environment is polluted in a large amount of abandoning.Because there is the very thin sebum of one deck on the human body skin surface, it is bioelectric non-conductor, therefore in the prior art, when settling Electrocardiographic electrode block, be coated with conducting medium and eliminate sebum, electrode block is closely contacted with body surface, to receive faint heart biology electric current effectively, press the electrocardiogram study course, existing conducting medium adopts the conduction of preparation to stick with paste or saline.
The objective of the invention is to invent a kind of have repeatedly used electrode block and conductive liquid thereof.
The present invention is achieved in that the present invention is by paste block, conductive liquid absorption pad and conductive attachment button are formed, the composition of conductive liquid is: add sodium chloride crystal in 70%～75% medical disinfecting ethanol, make it become 70%～75% ethanol supersaturation salt solution.
Advantage of the present invention is: this electrode block is not owing to need to carry viscose glue, therefore can repeatedly use, 70%～75% ethanol itself is disinfectant, it is again organic solvent, can make the electrode block sterilization that can be repeatedly used to avoid cross infection, can dissolve, remove sebum again, to reduce the resistance value of skin.The supersaturation sodium chloride solution is good electrolyte, can guarantee that faint myocardial bioelectric current is transmitted on the heart electrode piece.
Fig. 1 is a front view of the present utility model.
Fig. 2 is an anti-view of the present utility model.
Provide most preferred embodiment of the present invention below in conjunction with legend: the heart electrode piece is by paste block (1), conductive liquid absorption pad (4) and lead connect button (3) and form, a system aperture (2) in the middle of paste block (1), to connect button (3), be fixed on the aperture (2), paste a conductive liquid absorption pad (4) at the recessed face that connects button (3), conductive liquid absorption pad (4) is contacted with connection button (3), get 75% medical disinfecting ethanol, add sodium chloride crystal, make it become 75% ethanol supersaturation salt solution and make conductive liquid, during use, the drop one to five that will conduct electricity drips on the conductive liquid absorption pad, then electrode block is tied up respectively in person under inspection left and right sides wrist and left carpus place with the nylon cingulum, can carry out the II lead electrocardiogram detection synchronous with ultrasoundcardiogram, clinical trial through half a year, by the electrocardiogram clear picture that the technical program produced, stable, dropping liquid can be kept 30-40 minute detection time, it is more than sufficient to make a kinetocardiography, inspection finishes, unclamp the nylon cingulum, conductive liquid is dripped several dropping on the conductive liquid absorption pad (4) again, can carry out next bit person under inspection's inspection.
Claims (2)
1, a kind of reusable heart electrode piece and conductive liquid is characterized in that described heart electrode piece by paste block (1), and conductive liquid absorption pad (4), lead connect button (3) and constitute.
2, a kind of reusable electrocardiogram utmost point piece and conductive liquid is characterized in that described conductive liquid is made up of the 75% ethanol supersaturation salt solution that 75% medical disinfecting ethanol and sodium chloride crystal mix.
