Problems solved by technology

[0002] In the field of fluid equipment technology, especially the peristaltic pump involved is gradually expanding its application range due to its sanitation, convenience and easy maintenance. However, the peristaltic pump has the disadvantages of unstable water flow and large water pulse amplitude, and the existing technology cannot effectively control it. Water flow pulses, especially in applications with precise flow requirements, are not allowed to exist, so pulse suppression equipment that can effectively suppress the amplitude of water flow pulses is required

Abstract

The invention discloses a fluid pulse rectifier which comprises a rectifier matrix, a pulse buffering film and a buffering film fixing piece, wherein an input source nipple and an output source nippleare arranged at the two ends of the rectifier matrix separately; a fluid cavity is formed in the middle of the rectifier matrix; a buffering wing is arranged at the input source nipple of the fluid cavity; and a left rectifying wing and a right rectifying wing are arranged on the two sides of the corresponding output source nipple. Pulse water flow output by a peristaltic pump is divided into twopaths through the buffering wing arranged in the fluid cavity, the two paths of water flow are rectified by the left rectifying wing and the right rectifying wing, the pulse buffering film releases water flow pulse to a buffering air cavity, and stable pulse-free water flow is output, so that the defect that the water flow of the peristaltic pump is unstable is overcome effectively; the fluid pulse rectifier can be used for blood pulse rectification of a blood transfusion pump in the medical field; and stable blood flow can reduce the medical risk and can play an important role in saving a patient at the key moment.

Description

Technical field: [0001] The invention relates to the technical field of fluid equipment, in particular to a fluid pulse rectifier. technical background: [0002] In the field of fluid equipment technology, especially the peristaltic pump involved is gradually expanding its application range due to its sanitation, convenience and easy maintenance. However, the peristaltic pump has the disadvantages of unstable water flow and large water pulse amplitude, and the existing technology cannot effectively control it. Water flow pulses, especially in applications with precise flow requirements, are not allowed to exist, so pulse suppression equipment that can effectively suppress the amplitude of water flow pulses is required. Invention content: [0003] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a fluid pulse rectifier, which can effectively control the amplitude of the water pulse. [0004] In order to solve the above ...
