Methods and devices for switching filters and medical apparatuses using the same are described. The method includes: detecting whether or not a frequency range of an input signal is changed from a first frequency range into a second frequency range; if changed, switching from a first filter to a second filter, and taking a sample value of the input signal at a current moment as an input value of the second filter at the current moment and sample values of the input signal at n moments before the current moment as input values of the second filter at the n moments, respectively, and taking output values of the first filter at m moments before the current moment as output values of the second filter at the m moments, to obtain an output value of the second filter at the current moment.

Mutation signal processing methods, devices and medical detecting apparatuses are described. The method includes detecting whether or not a mutation signal exists in an input signal; if the mutation signal exists in the input signal, processing the input signal by a filter to obtain an output signal, and updating a prestored difference value according to a difference value obtained by subtracting the output signal from the input signal; and if the mutation signal does not exist in the input signal, using a difference value obtained by subtracting the prestored difference value from the input signal as the output signal.

This disclosure relates to baseline restoration methods and apparatuses and medical detecting equipment thereof. The baseline restoration method comprises: determining whether there is a high-amplitude baseline in an input signal by previous k output signals (Y, . . . , Y) of a filter, where k is a natural number and k&#x2267;1; setting the previous m output signals (Y, . . . , Y) of the filter as Y' when there is a high-amplitude baseline in the input signal, where Y&#x2032; is a desired output signal of the filter; and using a current input signal X, the previous n input signals (X, . . . , X), and the previous m output signals (Y, . . . , Y) of said filter to obtain a current output signal Yof said filter.

Baseline restoration methods and apparatuses and medical detecting equipments thereof

This disclosure relates generally to medical devices, particularly to drawer-type paper tray structures for loading paper into electrocardiograph machines. A paper tray structure provided comprises a paper tray and a door component. The door component comprises a door located in front of the paper tray. The door component is connected to the paper tray movably and is configured to move repeatedly between a first position and a second position relative to the paper tray; the paper tray comprises a first restriction surface and a second restriction surface corresponding to the first and second positions respectively.
