Automatic calibration method and device for patient monitor printing

Abstract

The invention relates to an automatic calibration method and device for printing of a patient monitor. The patient monitor printing method comprises the following steps of: detecting working state information of a printer, and acquiring the state information; determining the working state of the printer according to the working state information; sending out a sensing signal when the working state is idle, and sensing location mark information which is preset on printing paper to acquire the position information of the printing paper; determining whether the printing is deviated or not according to the acquired position information of the printing paper; regulating positions of a start point and an end point of a printing baseline when the printing is deviated; and printing monitor data when the printing baseline is regulated and the printing is not deviated. According to the automatic calibration method and device for printing of the patient monitor, the problem that errors exist between screen displayed data and printed data is solved, the printing drive current is reduced, and the service life of a thermal printing head is prolonged.

Description

technical field [0001] The invention relates to a printing calibration method and device, in particular to a printing automatic calibration method and device related to monitors. Background technique [0002] At present, there are two main types of monitors on the market, one is ordinary monitors, which are mainly used in adults; the other is fetal monitors, which are mainly used in fetuses and mothers; the fetal monitoring of fetal monitors is mainly based on reference Fetal heart rate and uterine contraction pressure curve, that is, the monitoring of the fetal heart contraction monitoring curve (CTG), through which the fetal heart rate monitoring curve can be used to understand the situation of fetal development in time and monitor the entire growth process of the fetus. Allows the fetus to grow normally throughout pregnancy. With the continuous development of science and technology, human beings' awareness and pursuit of health are constantly increasing, and the concept ...

Problems solved by technology

Of course, in order to facilitate doctors to observe CTG curves in real time, and to selectively print data, and improve the convenience of monitoring, many manufacturers are actively developing real-time display and print CTG curves, and can make the printed data and display There is a small error in the data, but contrary to expectations, there is often a certain error between the printed data and the data displayed on the screen due to some unavoidable problems
