Description
Technical Field
The invention relates to the technical field of drip gauge weight monitoring, in particular to a weighing sensing dynamic compensation method, a weighing sensing dynamic compensation device, a weighing sensing dynamic compensation medium and electronic equipment.
Background
The existing drip process is basically managed manually. The method is in an empirical fuzzy management stage, and does not have scientific means for fine management. This greatly affects the quality of the treatment. Such as: intravenous drip of potassium chloride, for example, at too high a rate may cause a sudden rise in serum potassium to cause hyperkalemia, thereby inhibiting the myocardium, resulting in cardiac arrest in diastole. Since the serum potassium reaches 7.5 milliequivalents/liter, death is likely to occur. If 1 g of potassium chloride (13.9 meq) is pushed directly into the blood, it is obviously extremely dangerous to increase the serum potassium level immediately from the original level by 3 to 3.5 meq/l in a short period of time. The infusion rate of potassium chloride therefore generally requires dilution to a concentration of 0.3% and 4-6 ml per minute. If the glucose solution is infused too quickly, the body cannot fully utilize the glucose, and part of the glucose is discharged from the urine. The limit of glucose received per kilogram of body weight per hour was approximately 0.5g as analyzed. Therefore, when an adult is to infuse 10% glucose, 5 to 6ml per minute is suitable. In addition, it is not preferable to administer physiological saline too quickly because the solubility of sodium in physiological saline is similar to that of plasma, but the chlorine content is much higher than the plasma concentration (154 meq/L of chlorine in physiological saline, 103 meq/L of chlorine in plasma), and as a result of rapid infusion, chlorine ions are rapidly increased in the body. For example, when kidney function is healthy, excessive chloride ions can be discharged from urine to keep the balance among ions; when renal insufficiency occurs, hyperchlorhydric acidosis may occur. When the patient is quickly intravenous-transfused, the patient needs to be observed, because the venous transfusion is too fast, the blood dissolving amount is suddenly increased, the heart and lung load is excessive, and the serious patient can cause heart failure and pulmonary edema, which are especially frequently seen in patients with original heart and lung diseases or old patients. Therefore, when the infusion is rapidly performed at a rate of 10 ml/min or more, the nursing staff should accurately control the respiration rate and the pulse rate before the infusion, and for example, after the infusion, the respiration rate and the pulse rate are faster than before, and the drip rate should be slowed down for those with frequent cough, and the doctor should be immediately informed to perform the examination.
For example, a medical infusion bottle monitoring system disclosed in CN105194759A adopts a weight sensor to weigh a medicine bottle, and detects whether the infusion is completed through weight detection, so as to notify medical staff; however, the inventor thinks that strain-type weighing sensor (Load Cell) can be selected for use in actual use, because its technology is mature, simple structure, and low cost, but creep and temperature drift phenomenon that it exists, to the weight collection system that is in operating condition for a long time of high accuracy, when weighing medicine bottle through weight sensor, because the weight change of medicine bottle itself is relatively slow, because the influence of the more slowly changing variable of time drifting and temperature drifting to weighing data leads to the liquid medicine surplus and the drip speed that can't accurately monitor the drip process, therefore await improvement.

When the comprehensive variation is smaller than the sum of the liquid medicine variation threshold and the creep variation threshold, it is indicated that no temperature drift and creep or the temperature drift and creep are extremely small and can be ignored, and at the moment, the effective comprehensive output value is taken as the real medicine allowance. Specifically, the temperature compensation amount = temperature variation threshold value ×, temperature variation weight; when the first noise variation is smaller than the temperature variation threshold value, it is indicated that no temperature drift exists or the temperature drift is extremely small and can be ignored, at this time, the creep compensation amount is calculated, and the creep compensation amount = the creep variation threshold value and the creep variation weight.
The second noise variation = the first noise variation-the temperature compensation, that is, the temperature compensation in the first noise variation is eliminated as the second noise variation; if the second noise variation is not smaller than the creep variation threshold, it indicates that the first noise variation also contains creep, and then creep compensation quantity is calculated, and the creep compensation quantity = the creep variation threshold and the creep variation weight; and when the second noise variation is smaller than the creep variation threshold value, no creep or extremely small creep can be ignored, and at the moment, the real medicine residue = effective comprehensive output value-temperature compensation quantity.
After creep deformation and temperature drift compensation processing, the total error in the whole dripping process can be controlled within +/-500 mg, so that the influence of time drift and temperature drift on weighing data is reduced, and the liquid medicine allowance and the dripping speed in the dripping process are monitored more accurately.
In a preferred embodiment, the method further comprises the steps of uploading data to a cloud platform or a platform service layer, wherein the platform service layer performs product abstraction management and data analysis processing on the access equipment; so as to facilitate the follow-up information tracing and reappear the whole dripping process.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
