Technical Field

The utility model relates to the field of medical equipment, specifically a membrane oxygenator.

Background

Membrane oxygenators are common medical devices used in cardiac surgery for extracorporeal membrane oxygenation, and are typically secured in use about a patient's bed by means of an external support. During the specific use process of the membrane oxygenator, index determination needs to be carried out by reading scales on a transparent shell of the oxygenator. Meanwhile, more guide tubes are often inserted outside the oxygenator to exchange liquid. At present, most of the fixing supports in the market are in a metal ring structure, and the membrane oxygenator is placed into the metal ring of the fixing support from the top to support and fix. Two major problems exist with this type of mounting bracket: 1. the film oxygenator with a metal ring structure can shield scales on a transparent shell of the oxygenator due to certain height, so that data reading is difficult; 2. the existing membrane oxygenator is fixed with a column support near a sickbed and is inconvenient to disassemble. Therefore, it is really necessary to design a membrane oxygenator fixing support which has a simple structure, is convenient to use and has a good fixing effect.
