Embodiment 1

[0025] see Figure 1-2 As shown, the mapping contrast catheter includes a catheter tube body 1, and a first Luer connector 2 is installed at one end of the catheter tube body 1. The setting of the first Luer connector 2 is used to ensure the normal delivery of the guide wire, and at the same time It can be used to connect with other supporting devices. The surface of the catheter body 1 is covered with a push tube 4. Through the setting of the push tube 4, it is used to facilitate the push of the catheter body 1. The surface of the catheter body 1 is fixed on the sleeve Connected with several platinum-iridium developing rings 5, through the setting of the platinum-iridium developing rings 5, they are used to cooperate with external developing devices, so that the operator can mark and measure the imaging position through the external developing devices, and the platinum-iridium developing rings 5 Evenly respectively on the surface of the catheter tube body 1, through the setti...

Abstract

The invention relates to the technical field of medical instruments, and discloses a marking and measuring angiographic catheter, which comprises a catheter body; one end of the catheter body is provided with a first Luer taper; the surface of the catheter body is sleeved with a pushing tube; and the surface of the catheter body is fixedly sleeved with a plurality of platinum-iridium developing rings. According to the invention, by arranging the plurality of platinum-iridium developing rings evenly distributed on the surface of the catheter body, the developing effect of the catheter can be improved; marking and measuring functions are achieved; the timeliness of finding a focus in an interventional operation is improved; the success rate and accuracy of the operation are greatly increased; a medicament conveying groove communicated with a side hole is arranged in the catheter body; it is connected with a contrast agent injection device in cooperation with a medicament conveying pipe and a second Luer taper; a contrast agent is pushed; and a guide wire in the catheter body does not need to be pulled out in the process of pushing the contrast agent through the medicament conveying groove and the side hole, so that the time for pulling out the guide wire is saved, and the operation duration is shortened.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a mapping contrast catheter. Background technique [0002] Contrast catheter is a long polymer material catheter, which is used in angiography process. Its main function is to deliver contrast agent to the designated position in the vascular system to produce contrast effect. [0003] Coronary heart disease, coronary atherosclerosis and other multiple cardiovascular diseases, if the patient's condition is not controlled through timely and effective treatment, adverse events are likely to occur, posing a direct threat to the patient's life safety. Percutaneous coronary intervention (PCI) is a commonly used method in the clinical treatment of coronary heart disease, which can dredge narrowed or occluded coronary arteries and help improve myocardial blood perfusion. Angiography catheter is the most basic diagnostic medical device for coronary interventional treatment. ...
