Abstract

The utility model relates to a card-type electrolyte testing electrode matched with a dry-type electrolyte analyzer, and aims to solve the technical problem that a single test card can not meet the requirements for simultaneously measuring various electrolyte ions. In order to solve the technical problem, the technical point is that silver conductive lines are formed on an insulating substrate, an insulating layer is coated on part of both the insulating substrate and the silver conductive lines to form two groups of a plurality of corresponding grooves, silver chloride is formed on the silver conductive lines, various ion selectivity sensitive films are filled in the corresponding grooves, a double-sided adhesive tape with an opening A and an opening B is pasted at the part of the insulating layer, where the two groups of grooves are formed, to form a reagent accommodating layer, the reagent accommodating layer and a hydrophilic overlying plate form a standard cavity and a sample cavity which are mutually connected through a conductor, and a standard liquid dripping port and a sample dripping port, as well as an air vent A and an air vent B, are formed on the overlying plate. The utility model can be applied to both manufacture and application of card-type electrolyte electrodes, and has the advantages of more measurement parameters, rapidness and accuracy.

Description

A kind of and the supporting card form electrolyte test electrode of dry type blomelicalbloodgasandelectrolrteanalyzers

Technical field: the utility model relates to a kind of medical analytical test card, relates in particular to a kind of and the supporting card form electrolyte test electrode of dry type blomelicalbloodgasandelectrolrteanalyzers.

Background technology: at present, hospital adopts flow-type blood blomelicalbloodgasandelectrolrteanalyzers human body electrolyte concentration; This quasi-instrument generally adopts the conventional ion electrodes selective, and electrode structure is complicated, is difficult to automated production, and production cost is high; A conventional ion electrodes selective can only detect a parameter, needs during test the several piece combination of electrodes is got up to use; Flow-type blood blomelicalbloodgasandelectrolrteanalyzers needs start continuously, and constant drain is all arranged every year, uses and the maintenance cost height, is difficult to satisfy the other diagnostic test requirement of less basic hospital of sample size and bed.

Summary of the invention: the purpose of the utility model, technical scheme a kind of and the card form electrolyte test electrode that the dry type blomelicalbloodgasandelectrolrteanalyzers is supporting is proposed exactly, exist with the solution background technology: electrode structure is complicated, is difficult to automated production, and production cost is high; A conventional ion electrodes selective can only detect a parameter, needs during test the several piece combination of electrodes is got up to use, and use and maintenance cost height, be difficult to satisfy the other diagnostic test requirement of less basic hospital of sample size and bed.

Solving this technical problem the technical scheme that is adopted is: a kind of and supporting card form electrolyte test electrode of dry type blomelicalbloodgasandelectrolrteanalyzers; It is characterized in that on insulating substrate, forming silver-colored conducting wire through serigraphy, the part position on insulating substrate and silver-colored conducting wire forms insulation course, and it and silver-colored conducting wire form two groups of mutual corresponding groove of some quantity; On silver-colored conducting wire, form silver chloride; Various ion selectivity sensitive membrane are filled in the corresponding grooves, and the position part of two groups of grooves of insulation course is pasted the double sticky tape that has A opening and B opening, forms the reagent accommodating layer; The last cladding plate of it and possess hydrophilic property forms standard chamber and sample cavity; Two chambeies are connected by conductor, the liquid standard drop is set on the last cladding plate adds mouth and sample dropping mouth, and A blow vent and B blow vent also are set.Wherein, insulation course and silver-colored conducting wire form two groups of mutual corresponding groove of some quantity, and every group of quantity is at least 5.To form two groups of some quantity corresponding groove be 101,102,103,104; 105 and 111,112,113,114; 115, wherein, the mutual corresponding groove 101 in position and 111,102 and 112; 103 and 113,104 and 114,105 and 115, fill sodion, potassium ion, chlorion, calcium ion and pH sensitive membrane respectively.Conductor is a salt bridge.On silver-colored conducting wire, apply the electric slurry that contains silver chloride and form silver chloride.

The beneficial effect that the utility model and background technology comparison are had is: owing to adopt technique scheme; Test card is inserted the test card socket of blomelicalbloodgasandelectrolrteanalyzers; Drip titer and patient samples respectively to titer dropping mouth and sample dropping mouth then; Two kinds of liquid are formed the loop through the capillary action rapid diffusion through the salt bridge connection and with blomelicalbloodgasandelectrolrteanalyzers.Analyser is converted into ion concentration with the electric potential signal that detects and prints.The standard chamber of the utility model is less with the measurement cavity volume, and required blood volume is less during use, alleviates the patient suffering, has stopped cross pollution; The ion electrode sensitive membrane comprises potassium, sodium, chlorine, calcium and pH sensitive membrane, and sensitivity is higher; The quantity of measurement parameter can increase as required; Card form electrolyte-electrode and the combination of dry type blomelicalbloodgasandelectrolrteanalyzers are used, and can fast, accurately measure the multiple electrolyte concentration of human body fluid, have improved medical efficiency.
