Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to a carbon dioxide bottle heat preservation structure. BACKGROUND

[0002] Carbon dioxide cylinders are widely used in the medical field for endoscopic surgery, laparoscopic surgery and other scenarios. Their role is to inject carbon dioxide gas into the patient's body to maintain a clear surgical field. However, carbon dioxide cylinders have the following problems during use: 1. During use, the liquid carbon dioxide in the cylinder will gradually vaporize and release into the external environment. Because the vaporization process requires the absorption of a large amount of heat, the temperature of the bottle will drop significantly. When the bottle temperature and the ambient temperature differ greatly, the internal pressure of the cylinder will fluctuate, thereby affecting the stability of the gas output. In endoscopic surgery, fluctuations in gas pressure can make it difficult for doctors to accurately control the amount of gas injected, increasing the risk of surgery; 2. When the temperature of the carbon dioxide cylinder is lower than the dew point temperature of the environment, water vapor in the air will condense on the surface of the bottle, forming condensed water. Condensed water not only corrodes the surface of the cylinder, but can also drip onto the operating room floor, increasing the risk of slipping. In addition, the formation of condensed water can also cause the humidity of the local environment to rise, which can affect the sterile environment in the operating room; 3. The carbon dioxide cylinder will continue to absorb heat from the surrounding environment during use, causing the local temperature around the cylinder to drop. This temperature change can affect the temperature control system in the operating room, increase energy consumption, and even adversely affect the comfort of medical staff and patients.

[0003] Currently, the common carbon dioxide cylinder heat preservation devices on the market are mostly fixed wrapping structures, which have the following defects: 1. Poor adaptability: fixed heat preservation sleeves are usually only suitable for cylinders of a specific size and cannot be flexibly adapted to cylinders of different specifications; 2. Installation is not convenient: traditional heat preservation sleeves mostly use zippers or buttons for fixation, and the installation and removal process is tedious, making it difficult to meet the needs of rapid operation in the operating room; 3. Limited heat preservation effect: traditional heat preservation materials (such as foam plastic or ordinary fiber) have poor heat preservation performance and are difficult to effectively suppress temperature fluctuations in the cylinder.
