Description

Super high molecular artificial lung oxygenation module

Technical Field

The utility model relates to an artificial lung of life support technology, in particular to an ultrahigh molecular artificial lung oxygenation module in an artificial lung product made of ultrahigh molecular materials.

Background

Currently, through improvements in membrane materials, optimization design, and experimental assessment and clinical evaluation of various properties, artificial lung research is focused on improving gas exchange capacity and biocompatibility, providing a more reliable means for rescuing a patient's life. The artificial lung is a life support technology, and can be used when the lung function of the human body fails to maintain sufficient oxygen supply of human organs, or can be permanently implanted into the human body to partially or completely replace the lung function of the human body in the long-term development.

The artificial lung in the market at present can be developed from the original vertical-screen type, rotary-disk type and bubbling type artificial lung products to the microporous hollow fiber membrane type artificial lung products widely adopted nowadays according to the structural form, but the artificial lung products in the structural forms have the following defects:

1. the two artificial lungs are limited in oxygenation performance, firstly pre-filled with oxygen, large in pre-filling amount, complex in operation process and low in safety performance, and are eliminated.

2. The bubbling artificial lung is characterized in that oxygen is directly introduced into blood for gas exchange, so that the blood is damaged to a certain extent, and qi and blood are easy to directly contact to cause diseases such as air embolism and the like.

3. A microporous hollow fiber membrane type artificial lung is a membrane made of hollow fibers by bundling, the module is divided into an inner cavity and an outer cavity, the two cavities can exchange materials through the hollow membrane wall, and can simulate certain functions of a microvascular, but because the membrane material and the micropores have different sizes, the surfaces of the hollow fibers are coated with coating layers, the relative molecular mass of interception is different, and the oxygenation quality is limited.

The artificial lung product is limited by the structural form and the selected materials, and the first two types of oxygenators obviously cannot meet the requirements of clinical use; the microporous hollow fiber membrane type artificial lung is a membrane made of hollow fiber bundles, so that the area of the hollow fiber membrane is influenced, the exchange capacity of the artificial lung oxygenator for oxygen is limited, the phenomena that the membrane pores are blocked by plasma and blood components are easy to deposit and the like easily occur, and in addition, the clinical service life of the microporous hollow fiber membrane type artificial lung oxygenator is short, so that the use cost is high.

In view of this, the development of a novel artificial lung oxygenator which can be widely applied to the rescue treatment of respiratory failure and has in vitro life support becomes a new target sought by researchers in the field.
