Problems solved by technology

The common disadvantage of these methods is that the adjustment speed is slow, and the actual adjustment time of the machine lags behind the human's expected adjustment time.
Not only is time wasted, sometimes due to the slow adjustment of parameters, it will increase the safety risk of the medical device in use

Embodiment Construction

[0034] The embodiments of the present invention are described below, and the embodiments do not constitute a limitation to the present invention.

[0035] The working principle of the present invention: according to the characteristics of the pulse signal, the pulse number of the signal reflects the angle of rotation, and the phase reflects the direction of rotation, so that mechanical quantities such as the rotation direction of the rotating shaft and the variation of parameters can be reflected in the form of pulse signals.

[0036] Based on the above theory, the present invention provides an embodiment. This embodiment proposes a method for regulating the parameters of a blood component separator with an encoder, such as figure 1 As shown, the method includes the following steps:

[0037] Step A. The encoder converts the mechanical quantity of the rotating shaft into a pulse signal through the knob.

[0038] By rotating the knob on the rotary shaft of the encoder, the rota...

Abstract

The invention discloses a regulation and control method of a blood component separator and a blood component separator. The method comprises the following steps that: a rotary knob of an encoder rotating shaft is rotated to rotate the rotating shaft of the encoder for regulation and control, and the encoder transmits the mechanical quantity of the rotating shaft to a main control system of a blood component separator in a pulse signal mode; the main control system decodes the received pulse signals, records the number of pulse signals, detects changes of the pulse signal phases, and transmits a control instruction being information of the number of the pulse signals and the phase changes to to-be-control-parameter equipment. In addition, the invention also discloses a blood component separator using the regulation and control method. According to the technical scheme, the fast degree of parameter adjustment can be controlled autonomously by the user; the speed of the blood component separator during parameter adjustment can be accelerated effectively; and the safety risk coefficient of medical equipment during application can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a method for regulating parameters of a blood component separator and the blood component separator. Background technique [0002] The blood component separator is a device with the function of separating blood components, mainly used for the collection of plasma or platelets. The separator is mainly composed of a centrifuge, a blood pump, a pressurized cuff, weighing components, a display screen and a control system. When blood is separated, it is necessary to adjust various parameters of the separation process, such as the speed of the centrifuge, the speed of the blood pump, the amount of blood collected, etc. are all parameters to be controlled by the separator. [0003] Although there are also automatic control separators now, most of the current blood component separators use key input when adjusting parameters, and some use touch screen input. The common disadv...
