Linkage control device and blood gas analyzer adopting same

Abstract

The invention relates to a linkage control device. The linkage control device comprises a power unit and a rotating component provided with bosses, wherein the power unit generates power to drive the rotating component to rotate. The linkage control device also comprises valve components, a signal control unit, sensing switches and sensing pins, wherein the valve components are matched with the bosses of the rotating component in a pushing manner; the signal control unit controls the start or stop of the power unit; the sensing switches are connected with the signal control unit via signals; and the sensing pins are arranged together with the sensing switches in pairs and are arranged on the rotating component. The linkage control device can realize accurate control of time sequences of various liquid and gas switches, avoid disorders caused by mutual influence in the process, minimize the cost and achieve the best control effect. Besides, the linkage control device has simple structure, lower cost and stable and accurate linkage guarantees.

Description

technical field [0001] The present invention relates to the field of medical instruments, in particular to a linkage control device in the field of medical instruments; the present invention also relates to a blood gas analyzer. Background technique [0002] The switch control structure is widely used in mechanical equipment. The switch control methods currently on the market mainly rely on electromagnetic force switches or mechanical switches to realize the opening and closing control of liquid circuits, gas circuits, and circuits. This point-to-point direct control method can effectively control the switch to be controlled in a short time. For example, the power switch of the machine, the valve switch of the pipeline, etc., can use mechanical switches to realize manual control or use electromagnetic switches to realize circuit automatic control. [0003] In precision equipment, mechanical switches cannot realize the linkage control of each switch through manual operation,...

Problems solved by technology

However, this new type of cam switch cannot be used for more switch control, especially in precision medical equipment with more switches, and it is impossible to achieve precise linkage control for each switch

[0005]With the development of technology, for precision medical equipment, the requirements for switch control are getting higher and higher, such as in blood gas analyzers, blood analyzers and biochemical analysis In medical equipment such as instruments, there are linkage controls for liquid circuits, gas circuits, circuits, etc. The cost of the control switch
