Description
Technical field
The utility model relates to instrument and meter equipment technical field, specifically relates to a kind of for measuring the device of haemodialysis dosing pH value and conductivity.
Background technology
In the hemodialysis process of medical industry, for guaranteeing patient's curative effect and safety, not only need to guarantee the accurate ratio of reverse osmosis water and concentrate, also to continue to monitor the accuracy of composition, therefore to using haemodialysis dosing pH value and conductivity to measure monitoring in this quasi-instrument, be absolutely necessary.And at present, existing conductance instrument is mainly used in the fields such as petrochemical industry, electric power, metallurgy, ocean and agricultural, fewer for the conductivity meter of measuring dislysate.Due to the singularity of dislysate, general conductance instrument is measured and is had larger measuring error for dialysate concentration, can not follow the tracks of in time the variation that electrical conductivity of solution is small.In addition, current measurement mechanism structure is also comparatively complicated, and making maintenance difficulty is large, and cost is high; Be subject to the interference of external environment, the easy shortcoming such as broken, electrode polarization and electrode corrosion, cause when measuring dislysate pH value measuring accuracy not high, affect the accurate measurement to dialysate concentration.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model discloses a kind of for measuring the device of haemodialysis dosing pH value and conductivity, it simple in structure, volume is little, measure quick and precisely.
The utility model is by the following technical solutions:
A kind of for measuring the device of haemodialysis dosing pH value and conductivity, comprise holder and be fixed on the pressing plate on holder, in described holder, have vertically a sealing through hole, described sealing through hole two ends are connected to respectively conductivity probe and wire contact, and one end that described wire contact stretches into through hole is all welded with metallic channel; In described sealing through hole, be also provided with electrode, described electrode two ends are welded with contact conductor, and described contact conductor is drawn by metallic channel guiding line contact; Described holder one side is provided with oscillatory circuit box and a plurality of golden ridge, and described golden ridge head all stretches in the through hole of holder.
Preferably, described golden ridge is four, and four golden ridge intervals are equally spaced.
Preferably, described oscillatory circuit box is between every two pairs of golden ridges.
The beneficial effect the utlity model has: simple in structure, convenient for installation and maintenance, with low cost, stable performance, electrode and capacity effect while reducing conductivity measurement, realizing haemodialysis dosing pH value and conductivity measures fast and accurately, can be by the monitoring of pH value and conductivity values constantly being adjusted in dialysis procedure to na concn, control hypertension, improve cardiovascular stability, reduce the generation of Patients Undergoing Hemodialysis complication.
