Speed reduction device, speed reduction system and speed reduction method

Abstract

The invention discloses a speed reduction device, a speed reduction system and a speed reduction method. The invention provides the non-pneumatic sample tube speed reduction device, the speed reduction system and the speed reduction method which are used in a pneumatic transmission system and do not need to modify a transmission pipeline. The speed reduction device comprises a first assembly, wherein the first assembly is provided with a through groove for radially limiting a sample tube; a second assembly provided with elastic contact parts, wherein the elastic contact parts and the groove bottom of the through groove are arranged at intervals, and the elastic contact parts and the through groove form a sample channel; and a diameter changing device provided with a moving end, wherein the moving end acts on the first assembly and / or the second assembly so that the drift diameter of the sample channel can have a gradually-decreasing change trend. The speed reduction device, the speed reduction system and the speed reduction method have the advantages of being convenient to implement, relatively simple in control precision requirement and the like.

Description

technical field [0001] The invention relates to the technical field of pneumatic transmission, in particular to a deceleration device, a deceleration system and a deceleration method. Background technique [0002] In the existing medical environment, many hospitals have successively installed pneumatic transmission systems for clinical samples due to the need to solve human efficiency problems, improve patient satisfaction, and connect with existing automation systems. The system is fast, efficient, and fast. The sample is transmitted to the designated place to achieve one-to-one, point-to-point reliable transmission. However, because it is driven by compressed air, the sample tube performs accelerated or high-speed motion in the transmission pipeline, so at the end of the transmission, if no measures are taken to stop the sample tube slowly, high-speed impact may occur, which may cause sample quality, Index parameters etc. are damaged. [0003] In view of the above proble...
