Abstract

A gas supply device for a digestive endoscope comprises a gas storage tank for storing gas, a gas source input interface connected with the gas storage tank, a gas pressure monitor for monitoring the gas pressure of the gas source input interface, a pressure reduction module for regulating the pressure of the gas output by the gas storage tank to the bearable pressure range, an output flow monitor connected with the pressure reduction module and monitoring the real-time flow of the gas, a gas source output interface connected with the output flow monitor, and a gas injection bottle connected with a water injection bottle interface of the digestive endoscope; and a gas inlet interface is arranged on a gas injection bottle and is connected with the gas source output interface in a sealing manner. The gas supply device for the digestive endoscope has the advantages that the gas source can be directly changed without changing the original structure of the endoscope.

Description

technical field [0001] The invention relates to a gas supply device for digestive endoscope. Background technique [0002] In the field of digestive endoscopy, air is usually used as the medium. By injecting air and water into the patient's natural cavity, it can provide a suitable surgical field of view and space for digestive endoscopy, and assist surgical treatment. With the development of digestive endoscopic technology, more and more high-frequency electrotherapy is used in digestive endoscopic treatment, and there is a risk of tissue burns in patients when using air medium. [0003] The advantages of using carbon dioxide gas are twofold: [0004] One is that carbon dioxide, as an inert gas, has high safety when using high-frequency electric knife for cutting and coagulation operations, and can avoid burns of human tissues. Therefore, the use of carbon dioxide gas medium has become a necessary safety condition for carrying out high-frequency electrotherapy operations ...
