Problems solved by technology

[0004] The infusion monitor using the traditional weighing sensor tare weight reset has the following disadvantages: the nurse on duty needs to manually press the button to reset the tare weight before the infusion, which increases the workload of the nurses, the steps become cumbersome, and the nurses also forget If the zero point of the tare weight is reset to zero, it will have an inaccurate effect on the alarm of the remaining liquid volume.
If there is no manual intervention to return to zero before using the load cell, the tare zero point of the sensor will shift more and more over time, so that the alarm of the remaining amount of infusion cannot be accurately performed

Embodiment Construction

[0028] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] The load cell is mainly composed of four parts: sensitive element, transformation element, measuring element and auxiliary power supply. Among them, the sensitive element is used to directly feel the weight of the measured object and output other quantities related to its quality; the transformation element is used to convert The output of the sensitive element is transformed into a certain easy-to-measure signal; the measuring element is used to convert the easy-to-measure signal output by the transforming element into an electrical signal; the auxiliary power supply is used to provide an energy source for the electrical signal output by the measuring element.

Abstract

The present invention relates to a method and a device for infusion inspection of charging state automatic calibration and measurement basis. The device achieves automatic zero resetting of tare through the following steps: it is detected whether an infusion monitor is in a charging state or not and whether the infusion monitor is in a vertical suspension state or not, when the infusion monitor isin the charging state and in the vertical suspension state, a zero load state is identified, and the infusion monitor can automatically perform tare zero resetting operation of a weighing sensor.

Description

technical field [0001] The invention relates to a tare weight reset method of an infusion monitor and a corresponding device. Background technique [0002] The hospital mobile infusion closed-loop monitoring system monitors the real-time changes in the gravity of the infusion bags and infusion bottles, so as to provide nurses with the alarm function of the remaining liquid volume and drip speed for the current patient's infusion situation, which can minimize the need for nurses to run back and forth to check the infusion The tedious workload of the situation, to achieve precise care, improve work efficiency. How to accurately obtain the real-time weight of the infusion solution is the most critical part of the infusion monitoring system, and the precise weighing function of the infusion monitor is the most critical in this link. [0003] The current weighing principle of the load cell is the difference between the gravity ADC value of the mounted object and the empty tare A...
