Shaft medical gas multifunctional control system

Abstract

The invention provides a shaft medical gas multifunctional control system comprising connections and monitors applied between a shaft gas source pipeline and shunt pipelines of all floors of a hospital. Branch gas pipes and a bottom plate are included, the branch gas pipes are correspondingly connected with gas pipelines corresponding to medical gas sources in the shaft gas source pipeline, and the bottom plate is convenient for installation and fixing of all branch gas pipes. All the branch gas pipes on the bottom plate are each provided with a ball valve and a pressure gage. The branch gas pipe corresponding to medical oxygen on the bottom plate is further provided with a two-level valve assembly, and the two-level valve assembly is used for medical oxygen decompression and has a two-wayreserve switch function. Through the two-way main control and reserve mutual switch control mode of the two-level valve assembly, the layout arrangement of the whole pipeline is shrunk, in addition,the structure is simple, control is convenient, engineering construction and installation of the whole shaft medical gas multifunctional control system is convenient, meanwhile joints are reduced effectively, the integration level of the shaft medical gas multifunctional control system and sealing reliability are improved, and subsequent pipeline monitoring control and overhaul maintenance are convenient.

Description

[0001] 【Technical field】 [0002] The invention relates to the control technology of medical gas pipelines, in particular to a multifunctional control system for shaft medical gas. [0003] 【Background technique】 [0004] Medical gas systems such as medical oxygen, negative pressure suction, and compressed air are called life support systems, which are special products directly related to people's lives and health, so the quality requirements for products are rigid. Therefore, the supply system for medical oxygen, negative pressure suction, compressed air and other medical gases is an important and indispensable part of a hospital, which includes medical oxygen system, negative pressure suction system, compressed air system, laughing gas ( N2O), nitrogen system, carbon dioxide system and central workstation, etc., and through the medical gas central pipeline system, the hospital can obtain a powerful gas supply system to ensure the efficient operation of the hospital's medical ...

AI Technical Summary

Problems solved by technology

[0006] Because there are many types of medical gases used in each department of the hospital, such as oxygen, negative pressure, carbon dioxide, nitrogen, compressed air, anesthesia waste gas discharge, etc.; moreover, there are many gas consumption areas in the hospital and are widely distributed, such as operating rooms, Wards, consulting rooms, etc., and the medical gases used in each gas consumption area are generally different, and the situation is very complicated, which makes the installation of the gas supply pipeline very complicated

At the same time, in order to ensure the safety of gas consumption, hospital management personnel need to understand the gas consumption situation in each gas consumption area, so they need to inspect the use status of each gas consumption equipment in each gas consumption area one by one, and need to set up corresponding testing equipment to A comprehensive and timely understanding of the gas consumption of the whole hospital or each department; for example, if figure 1 As shown, due to the complexity of the hospital's gas consumption situation, when the vertical gas source pipeline 1a connected by the central working room or the central gas supply station enters each building of the hospital, it is necessary to drain the multi-channel gas source pipelines respectively The copper pipe 2a leads the pipeline gas to the valve box 3a that controls the on-off of each gas source pipeline, and the gas source pressure input into the vertical gas source pipeline 1a by the central working room or the central gas supply station is generally compared to High, before each gas source pipeline enters the final gas terminal, it is necessary to install a secondary pressure stabilization box 4a that decompresses and stabilizes the gas source; at the same time, each gas source pipeline also needs to install a The flowmeter 5a for detecting the source flow, and the maintenance valve 6a for pipeline control during the maintenance of the flowmeter; among them, the shaft-type gas source pipeline enters the pipeline installation room of each floor of the hospital, due to the small wall area and the installation space Narrow and small, coupled with the layout of multiple branch gas source pipelines, valve box 3a, secondary pressure stabilization box 4a, flow meter 5a and maintenance valve 6a, it is difficult to install the project, and it is impossible to lay pipelines in a small space It is not only inconvenient to detect and control the gas consumption of subsequent pipelines, but also in the early stage of engineering construction and installation, which increases the amount of engineering and increases the difficulty of construction.
