Problems solved by technology

[0003] For the structure of the heart and great vessels, the measurement of pressure and flow velocity is extremely important, which can help to judge the function of the heart and blood vessels, as well as the effect of occlusion, while the existing occluder delivery device does not have a structure for measuring pressure and flow velocity , due to the effect of blood pressure in the body, the effect of backflow cannot be achieved, and the delivery effect of the occluder is not good

Abstract

The invention provides a conveying device for atrial septal defect occlusion. The conveying device comprises a long catheter, wherein one end of the long catheter is fixedly connected with a leakage-proof joint, the back end of the leakage-proof joint is connected with a switching joint communicating with the long catheter through a connecting tube, a freely moving inner core is inserted and connected in the long catheter, a return joint is fixedly arranged at the back end of the switching joint, an operating handle is fixedly arranged at the tail end of the return joint, a mounting hole is formed in the outer wall of the bottom of the return joint, a stop valve is fixedly mounted in the mounting hole, and the bottom end of the stop valve is connected with a return pipe. The conveying device can determine the pressure and flow speed in a target position and contributes to judgment of the release environment of an occluder, the multiple joints are made of ABS, are very easy to produce,process and implement and facilitate release of the occlude, meanwhile, the inner core can reliably drive the occlude to reach a designated occlusion position, and the safety of the device for patientoperation is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a delivery device for atrial septal defect occlusion. Background technique [0002] The known occluder delivery device is a special instrument for delivering an occluder for interventional treatment of congenital heart disease, and is mainly composed of a long sheath for entering blood vessels in the body and a short sheath for loading the occluder. [0003] For the structure of the heart and great vessels, the measurement of pressure and flow velocity is extremely important, which can help to judge the function of the heart and blood vessels, as well as the effect of occlusion, while the existing occluder delivery device does not have a structure for measuring pressure and flow velocity , due to the effect of blood pressure in the body, the effect of backflow cannot be achieved, and the delivery effect of the occluder is not good. [0004] Therefore, it is necessary to invent a d...
