Problems solved by technology

When the internal bonding force of the soda lime product particles is poor and relatively soft, it is easy to generate a large amount of dust due to collision during transportation. Even if it is sieved before use, it is difficult to avoid the generation of fine powder during use.
And this is very dangerous in closed loop

Abstract

The invention discloses a medical carbon dioxide adsorbent and a preparation method thereof. The adsorbent comprises raw materials as follows: soda lime, LiOH, a humectant, deionized water, methyl violet and a disintegrating agent. The preparation method comprises preparation steps as follows: 1), soda lime is prepared; 2), soda lime powder, LiOH, the humectant and the deionized water are mixed, and a cylindrical bar with the diameter of 1-2 mm is extruded through an extrusion machine; 3), the cylindrical bar is dried and ground, and a finished product is obtained. The adsorbent has high adsorption capability and is low in cost, and powder is not easily produced.

Description

technical field [0001] The invention relates to the medical field, in particular to a carbon dioxide absorber and a preparation method thereof. Background technique [0002] Carbon dioxide adsorbent is an indispensable part of closed circuit anesthesia. Lime is the most commonly used adsorbent. Of course, there are many kinds of lime, calcium lime and soda lime, and soda lime is the most common adsorbent. There are many soda lime manufacturers in China, but the internal cohesion of soda lime product particles is weak and relatively soft, and it is easy to generate a lot of dust during transportation. This is very dangerous in closed loop anesthesia, so there is an urgent need to develop an adsorbent with strong adsorption and good stability. [0003] The friability of soda lime is an important indicator of its quality. When the internal cohesion of soda lime product particles is poor and relatively soft, it is easy to generate a large amount of dust due to collision during...
