Drawings
Embodiments of the invention will now be described with reference to the accompanying drawings, in which:
fig. 1 is a configuration view of a treatment cart body to which a membrane oxygenator homing status identification platform is applied according to an embodiment of the present invention.
Detailed Description
Embodiments of the membrane oxygenator homing status identification platform of the present invention will be described in detail below with reference to the accompanying drawings.
The membrane oxygenator can be divided into an adult membrane oxygenator and a pediatric membrane oxygenator according to different applicable people. Adult membrane oxygenators contain integral heat exchangers and pediatric membrane oxygenators do not.
There are many membrane oxygenators produced worldwide, and the basic structure of the membrane can be divided into a non-porous type and a porous type. The non-porous membrane oxygenator mainly consists of a silica gel membrane and is suitable for long-time perfusion. The porous membrane oxygenator is used in clinic frequently, and the selected materials are polytetramethylene, polypropylene and the like. The materials have good histocompatibility and strong gas exchange capacity, can effectively discharge carbon dioxide, but have unstable oxygenation performance if being infused for a long time.
The shape of the membrane oxygenator can be divided into a reel type, a flat plate folding type and a hollow fiber type. Rolled oxygen and performance stability, and membrane oxygenators of this type are used in ECMO therapy; the flat folding membrane oxygenator is formed by folding a breathing membrane into a sandwich shape, and qi and blood flow along one side; hollow fiber membrane oxygenators were released in the early eighties. The blood circulation can be divided into tube-shaped and tube-shaped according to the position of blood.
The membrane oxygenator can be classified into an open type and a closed type according to the venous return mode. The open membrane oxygenator is returned to the reflux chamber communicated with gas via vein, and the reflux chamber and the membrane oxygenator are connected into one integral for convenient use. The closed membrane oxygenator is a plastic bag which is returned to the vein and isolated from the atmosphere, reduces the pollution of blood, avoids the direct contact between the blood and gas and prevents the blood from emptying.
Current membrane oxygenators do not allow real-time monitoring of whether the membrane oxygenator is properly positioned on the treatment cart on which the various components of the gas exchanger are positioned during treatment of the patient using the gas exchanger, resulting in the inability to perform an on-site alarm when the membrane oxygenator is not properly parked.
In order to overcome the defects, the invention builds a membrane oxygenator homing state identification platform, and can effectively solve the corresponding technical problem.

Each piece of information obtained through the utilization of all types of monitoring will provide the necessary information to determine how the patient is responding to therapy. Documentation of all diagnostic results and exam findings is also an essential part of complete patient care. Without standardized record keeping, monitoring is not useful for patient care and can lead to erroneous conclusions. Records for criti-cal patients can be in the form of a table, flow sheet, or dot plot form (Figure 2-1). |
