A large flow decompression device for medical gas

Abstract

The invention discloses a medical gas large-flow decompression device, which comprises a decompression box body and a box door. An air inlet pipe and an air outlet pipe are arranged in the decompression box body, pressure gauges are arranged on the air inlet pipe and the air outlet pipe, and a hanging The decompression box is located in the suspension frame, and the air intake pipe and the air outlet pipe are equipped with shock absorbers, which are fixedly connected with the inner side wall of the decompression box, and the pressure gauge is connected to the inner side of the decompression box through the adjustment seat. The wall is fixedly connected; the design of the suspension frame can facilitate the installation and fixation of the decompression box, ensure the stability of the decompression box, and improve the safety performance. At the same time, the design of the shock absorber makes the pipeline structure in the decompression box It is more stable and reduces the vibration amplitude of the pipeline caused by the air flow pulsation in the gas delivery, and the design of the adjustment seat can facilitate the installation of the pressure gauge and ensure the verticality of the pressure gauge installation, thereby improving the accuracy of the pressure gauge measurement value, and through The adjustment seat can also change the height of the pressure gauge up and down.

Description

technical field [0001] The invention belongs to the technical field of medical gas decompression, and in particular relates to a large-flow medical gas decompression device. Background technique [0002] Medical gas refers to the gas used in medical treatment. Mainly used for treatment, anesthesia, driving medical equipment, medical experiments, culture of bacteria and embryos. Commonly used gases are: oxygen, nitrous oxide, argon, helium, nitrogen, compressed air and mixed gases. Before the medical gas is delivered to the end of use, it needs to be decompressed to decompress the high-pressure gas into the required low-pressure gas. The decompression of medical gases generally uses a special decompression box for decompression treatment. The pressure gauge is an essential part in the decompression box, and the pressure change of the delivered gas can be monitored through the pressure gauge. When the pressure gauge is installed, the verticality of the pressure gauge shoul...

AI Technical Summary

Problems solved by technology

When the pressure gauge is installed, the verticality of the pressure gauge should be ensured as much as possible, but in the prior art, there will still be a large deviation during the installation process of the pressure gauge, which will affect the test accuracy of the pressure value

Moreover, when the existing decompression box is installed, it is generally placed directly in the tube well, which makes the stability of the decompression box poor and increases potential safety hazards.
