Technical Field
The utility model relates to an extracorporeal circulation carbon dioxide cleaner, which belongs to the technical field of medical instruments.
Background
The metabolism of human organ tissues can generate a large amount of carbon dioxide, and the respiratory organ, namely the lung of the human body oxidizes venous blood into arterial blood to discharge carbon dioxide, so that the partial pressure of the carbon dioxide is reduced. The normal value of the partial pressure of carbon dioxide in arterial blood is in the range of 35mmHg to 45mmHg, the partial pressure of carbon dioxide exceeding 45mmHg is called "high partial pressure of carbon dioxide" or "increased partial pressure of carbon dioxide", and hypoventilation is a possible cause of high partial pressure of carbon dioxide, and hypoventilation such as pulmonary failure, respiratory distress syndrome, etc. is likely to be caused. If the partial pressure of carbon dioxide in arterial blood is above 45mmHg, treatment may be required to reduce the partial pressure of carbon dioxide.
Currently, the medical field is mainly to treat hypoventilation by means of mechanical ventilation. Mechanical ventilation is a method of mechanical assistance to replace spontaneous breathing, typically accomplished using a ventilator.
However, mechanical ventilation has the following disadvantages:
Ventilators may cause lung injury, barotrauma, volume trauma, shear force trauma, and biological trauma, among others. In order to solve the defects of mechanical ventilation, it is necessary to provide an extracorporeal circulation carbon dioxide remover.

The utility model provides a technical scheme that above-mentioned problem adopted does: an extracorporeal circulation carbon dioxide remover comprises an oxygenation chamber, wherein the oxygenation chamber comprises an inner shell and an outer shell, a hollow fiber semi-permeable membrane tube is arranged between the inner shell and the outer shell, the left end and the right end of the hollow fiber semi-permeable membrane tube are encapsulated by mucilage glue to form end sockets, the left side and the right side of the oxygenation chamber are both provided with air chambers, the air chambers are both internally provided with cup-shaped occupiers, the outer side of the round cup-shaped occupier is provided with an end cover, a blood inlet channel or a bleeding channel is respectively formed among the air chambers at the left side and the right side, the round cup-shaped occupier and the end cover, the left side and the right side of the inner shell are respectively provided with an oxygenation chamber inlet and an oxygenation chamber outlet, the oxygenation chamber inlet and the oxygenation chamber outlet are respectively communicated with the blood inlet channel or the blood outlet channel, the left end cover and the right end cover are respectively provided with a blood inlet and a blood outlet, and the outer sides of the left air chamber and the right air chamber are respectively provided with an air outlet and an air inlet.
Furthermore, the hollow fiber semi-permeable membrane tube is made of polymethylpentene.
Furthermore, the inner shell and the outer shell are made of polycarbonate.
Compared with the prior art, the utility model has the advantages of:
1. The utility model achieves the purposes of oxygenating blood and removing carbon dioxide in an extracorporeal circulation mode, provides respiratory support for respiratory failure patients, and effectively solves the problems of the existing mechanical ventilation;
2. The utility model is in the shape of a cylinder with axial symmetry, the positions of the left and right side interfaces can be interchanged, and the operator only needs to ensure that the blood inlet and bleeding direction is opposite to the air inlet and outlet direction, thus the utility model is very convenient to use and can be used in a horizontal state or a vertical state;
3. The utility model discloses go into blood mouth and hemorrhage mouth department and all be provided with cup-shaped ware of taking up space for it is more smooth and easy to go into the hemorrhage of blood.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
Referring to fig. 1-3, the utility model relates to an extracorporeal circulation carbon dioxide remover, which comprises an oxygenation chamber 1, wherein the oxygenation chamber 1 comprises an inner shell 1.1 and an outer shell 1.2, a hollow fiber semi-permeable membrane tube 1.3 is arranged between the inner shell 1.1 and the outer shell 1.2, the left and right ends of the hollow fiber semi-permeable membrane tube 1.3 are sealed by mucilage glue to form a sealing head 1.4, air chambers 2 are arranged on the left and right sides of the oxygenation chamber 1, a round cup-shaped space 3 is arranged in each air chamber 2, an end cover 4 is arranged on the outer side of each round cup-shaped space 3, an inlet blood channel 5 or a bleeding channel 6 is respectively formed between the air chambers 2 on the left and right sides, an oxygenation chamber inlet 7 and an oxygenation chamber outlet 8 are respectively arranged on the left and right sides of the inner shell 1.1, the oxygenation chamber inlet 7 and the oxygenation chamber outlet 8 are respectively communicated with the inlet blood channel 5 or the bleeding channel 6, the left end cover 4 and the right end cover 4 are respectively provided with a blood inlet 9 and a blood outlet 10, and the outer sides of the left air chamber 2 and the right air chamber 2 are respectively provided with an exhaust port 11 and an air inlet 12;
The material of the hollow fiber semi-permeable membrane tube 1.3 is polymethylpentene (PMP);
The inner shell 1.1 and the outer shell 1.2 are made of Polycarbonate (PC).
The working principle is as follows:
When the oxygenation device is used clinically, venous blood of a patient enters the oxygenation chamber through the blood inlet channel, the blood travels outside the hollow fiber semi-permeable membrane tube, oxygen entering from the air inlet enters an inner hole of the hollow fiber semi-permeable membrane tube through the air chamber and exchanges gas with the blood in the oxygenation chamber, and carbon dioxide discharged after the oxygen is combined with the blood is discharged through the air outlet. The oxygenated blood is input into the blood system of the patient through the bleeding port, thereby completing the circulation process of the extracorporeal membrane lung oxygenation support therapy, replacing the functions of the lungs and supporting the life of the patient.
In addition, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement modes should fall within the protection scope of the claims of the present invention.
