Liquid distributing valve and medical equipment with same

Abstract

The invention is applicable to the technical field of medical equipment and discloses a liquid distributing valve and medical equipment with the same. The liquid distributing valve comprises a fixed plate and a movable plate which can rotate or move relative to the fixed plate. A sample quantifying passage is reserved on the movable plate. A sample collecting passage and a sample conveying passage which can be communicated with the sample quantifying passage respectively when the movable plate rotates to different positions are reserved on the fixed plate. A washing groove which is capable of feeding detergent is reserved on the fixed plate or the movable plate. The washing groove is arranged on an end face where the fixed plate is attached with the movable plate and located on the periphery of the sample conveying passage or / and the sample collecting passage. The medical equipment is provided with the liquid distributing valve. The liquid distributing valve is low in manufacturing cost and high in equipment reliability, has no washing dead angle, and avoids cross contamination.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a liquid separation valve and medical equipment with the liquid separation valve. Background technique [0002] At present, the liquid separation valve is a new type of fluid metering device used in medical instruments at home and abroad. It can directly intercept multiple fluid samples at the same time to achieve accurate quantitative and efficient distribution of samples. The current liquid separation valve, such as the blood separation valve, needs to realize the collection and distribution of samples through continuous mechanical actions during the measurement process. Frequent movements require the blood separation valve to have good wear resistance, corrosion resistance and Low coefficient of thermal expansion, so blood diverter valves are usually made of ceramic materials. There are several types of existing blood-distributing valves, but their princ...
