Description
Technical field
The present invention relates to a kind of detector, relate in particular to a kind of hemo system dislysate detector.
Background technology
The dislysate that haemodialysis control unit is used requires comparatively harsh in the performances such as conductivity, temperature, flow, pressure.If conductivity of dialysate is too high, patient's meeting blood pressure body rising because of high sodium, even stupor; If conductivity of dialysate is too low, patient can be because of low sodium low blood pressure, feel sick, vomiting, twitch and cause danger.The temperature of dislysate is set to 37 ℃ of left and right conventionally.If excess Temperature there will be haemolysis, if temperature surpasses 42 ℃, there will be significant hemolysis, even dead; If temperature is too low, can occur shivering, vessel retraction or blood pressure raise, vascular flow amount reduces, degradation under solute dispersion speed.Too high or too low temperature all can have a negative impact to patient, and consequence is hardly imaginable.
The flow of dislysate is set to 500ml/min conventionally, and the effect of flow and dialysis treatment has substantial connection.Flow is too low, dialyses insufficient, can affect patient's result for the treatment of; Flow is too high, although beneficial to patient, hospital has wasted resource.When dialyzer has blood coagulation or has thrombosis, when blood flow deficiency and venous return syringe needle come off, vein pressure will decline, if when the distortion obstruction of bloody path recirculatory pipe or backflow syringe needle occur to stop up, vein pressure will raise; When blood flow is not enough, angiosthenia will reduce; While having blood coagulation and thrombosis in dialyzer, angiosthenia will raise.Therefore, vein pressure and arterial blood pressure monitoring are accurate, very important concerning patient.The detection of dislysate pH can prevent from misplacing dialysis concentrate (as sanitizer) or preparation wrong and patient is caused danger.
As can be seen here, before haemodialysis, to the detection of the performances such as the temperature of dislysate, conductivity, pressure, flow pH, be vital, but to the detection of dislysate, be mostly the mode that adopts sub-indicator to detect separately at present, its operation is too lengthy and tedious, and needs the time of overspending.
In addition, existing hemo system dislysate detector also just improves mainly for the above-mentioned four indices that comprises temperature, conductivity, but has but ignored the impact of calcium ion concentration on haemodialysis in dislysate.
Due to noxious material retention in uremic patient body, cause active VitD (vitamin D) relatively or definitely not enough, small intestinal mucosa function is impaired, calcium absorbs and reduces, and glomerular filtration rate(GFR reduces, kidney row phosphorus obviously reduces, thereby ubiquity hypocalcemia and hyperphosphatemia.The dislysate that calcium ion concentration is too high should not be applied for a long time in haemodialysis, to avoid metastatic calcification; And the low dislysate of calcium ion concentration, because reduce patient's blood calcium after dialysis, exists the negative balance of calcium, therefore exist the patient of hypocalcemia to use.Therefore need to select rational Dialysate ca ++ ion concentration, it can provide zero or slight positive balance conventionally to blood calcium, and patient's blood pressure is had no significant effect.
But, for different patients, should select corresponding calcium ion concentration dislysate, if patient takes calcium carbonate or calcium acetate as phosphate binder, should use medium calcium concentration on the low side; If patient does not take phosphate binder, or with the phosphate binder of calcic not, can adopt higher calcium concentration; For the patient of heavy dose of VitD treatment, unpowered patient with bone disease, or because other cause hypercalcemia patient, available low calcium dislysate is dialysed.Therefore, dislysate should be noted the calcium concentration of individuation.
