[0002] Medical catheters are a type of medical device. Their structures and compositions vary depending on different types, but generally include the following parts: infusion tube: the main part of the catheter, usually a flexible plastic tube, used to transport drugs, liquids, gases, etc.; connector: connects the catheter to an infusion bag, syringe, or other device, usually made of plastic or metal; port: the opening at the end of the catheter, used to insert, fix, or connect other devices; guiding needle or catheter guide wire: used when inserting the catheter, usually made of metal or plastic.

[0003] For example, the Chinese authorized patent with the publication number CN208809258U (a connector for a nasal oxygen tube and a tracheal catheter in an operating room): includes a plug disk and a plug tube; the plug disk is provided with ventilation holes and suction holes that penetrate the top and bottom surfaces of the plug disk, and the side of the plug disk is provided with insertion holes that cooperate with the oxygen outlet tube on the nasal oxygen tube; the plug tube is a tube body with a through hole inside, the plug tube is fixed on the bottom surface of the plug disk, the diameter of the plug tube is smaller than that of the plug disk, and the plug tube and the plug disk are coaxially arranged; the ventilation holes, suction holes, and insertion holes are all communicated with the through hole. The utility model provides a connector that can adapt to the shapes of the oxygen outlet tube on the nasal oxygen tube and the port of the tracheal catheter, enabling the nasal oxygen tube and the tracheal catheter to be connected by plugging. This connection method is simple and reliable; the utility model reserves air holes for the patient to exhale gas or perform suction operations on the connector, and there is no need to remove the connector during suction, making the suction operation more convenient.

[0004] However, the sealing performance of the catheter connectors in the above-mentioned prior art is poor. During the operation of doctors, in special cases, blood or physiological saline splashes onto the catheter connectors, resulting in problems such as electrical performance short circuits; therefore, it does not meet the existing requirements, and for this reason, we propose an operating room catheter connector with a liquid-proof function.
