Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0026] refer to figure 1 , an oxygen supply system using a liquid oxygen tank, comprising a Dewar tank 1, a vaporizer 2, a monitoring device, an alarm device and a control unit 6.

[0027] The Dewar tank 1 is connected to the inlet of the vaporizer 2 through the pipeline 3, and the outlet of the vaporizer 2 is connected to the oxygen terminal of the ward.

[0028] The monitoring device includes a weight monitoring device and a pressure detection device. The weight monitoring device is used to measure the weight parameter of the Dewar tank, and the pressure detection device is used to measure the pressure of the oxygen output from the vaporizer. The weight monitoring device and the pressure detection device are respectively connected with the control unit. The weight and pressure paramet...

Abstract

The invention discloses an oxygen supply system adopting a liquid oxygen tank and a control method. The oxygen supply system comprises a liquid oxygen container, a vaporizer, a monitoring device and acontrol unit; the liquid oxygen container is connected with the inlet of the vaporizer through a pipeline; the outlet of the vaporizer is connected with an oxygen using terminal of an inpatient area;a pressure detecting device and a gravity detecting device are arranged on the vaporizer and the liquid oxygen container separately, monitor the oxygen pressure and the oxygen quantity, and send themonitoring data to the control unit at the same time; and the control unit compares the monitoring data with a preset threshold value to further output an alarm signal, so that real-time monitoring ofthe dewar tank state and oxygen pressure is realized, and oxygen supply stability is improved.

Description

technical field [0001] The invention relates to the field of medical oxygen supply systems, in particular to an oxygen supply system using a liquid oxygen tank and a control method. Background technique [0002] At present, medical oxygen supply equipment is an indispensable facility in hospital construction. At present, most hospitals in China generally use centralized oxygen supply to deliver oxygen to wards. There are special liquid oxygen stations in hospitals. In some small medical institutions or Some medical units with small scale and small places do not need a large-scale oxygen supply system. They mainly use Dewar tanks to bottle oxygen, and put multiple oxygen cylinders together to form a small oxygen supply system to meet medical needs. [0003] The safety of the oxygen supply system is extremely important. The hospital has high requirements on the safety and reliability of the oxygen supply system. Once a failure occurs, it will have a great impact on the work o...
