Abstract

The invention is suitable for the technical field of medical instruments, and relates to a multi-parallel control valve mechanism. The multi-parallel control valve mechanism comprises a valve shell and a valve core; the valve core is arranged in the valve shell, and the portion, on one side of the valve core in the extending direction, of the upper part of the valve shell is hollow; the valve corecomprises a plurality of roller pins, a plurality of rollers and two fixing plates, the two ends of the roller pins are each fixed by one fixing plate, and the roller pins are sleeved with the rollers; and a plurality of hoses are placed on the valve shell, a motor drives the rollers in the valve core to rotate, and the hoses are controlled to be opened or closed according to the condition that whether the rollers extrude the hoses or not. The valve core is composed of the rollers and the roller pins, the structure is simple, and machining is convenient; and the rollers and the hoses are in direct contact and are in rolling friction, so that a push rod and a springback device are not needed, abrasion and lubrication in the movement process do not need to be considered, time and labor aresaved, and high efficiency and reliability are achieved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a multi-parallel control valve mechanism and medical equipment. Background technique [0002] The main components of the current multi-parallel control valve include special-shaped cams, push rods and fixed splints. Among them, the multiple and special-shaped cams are formed by merging multiple cams, and are often formed by integral processing of multiple cams. The number of push rods is related to the number of controlled air pipes, and the fixed splint is used to fix the air pipes. Multiple parallel cams include high pair and low pair. Through the rotation of the cam group, each push rod is in contact with the high pair and the low pair respectively. The principle is that when the push rod contacts the high pair of the cam group, the contact between the push rod and the fixed plate The gap becomes smaller, thereby squeezing the hose to block it, and the p...
