Aorta blocking balloon device based on 18F-FDG detection and positioning

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an aorta blocking balloon device based on 18F-FDG detection and positioning, which comprises a catheter, a balloon is arranged at the front end of the catheter, an injection tube communicated with the balloon penetrates through the interior of the catheter, and an injector communicated with the injection tube is arranged at the rear end of the catheter; before aorta blocking hemostasis is executed, the device can assist in determining the general anatomical orientation of the balloon in the body and increasing the success rate of disposable balloon blocking, and has the following advantages that firstly, the device has lower requirements on the technical ability and experience of first-aid implementers, and can be mastered according to program operation after simple training; secondly, the 18F-FDG is a common medical medicament, the availability and the medication cost can be controlled, and correspondingly, the handheld gamma ray detector for detecting the 18F-FDG is relatively low in cost; the technical operation procedure is simple, and the risk of additionally increasing bleeding time is small; fourthly, the half-life period of 18F is short, and secondary injury to patients is small.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an aortic blocking balloon device based on 18F-FDG detection and positioning. Background technique [0002] Alternative methods of aortic occlusion include direct clamping by emergency surgery and emergency endovascular balloon occlusion. The necessary condition for direct clamping in emergency surgery is the treatment in the operating room in the hospital, and in the pre-hospital and other conditions where the operation is not available, intravascular balloon occlusion is the only available emergency technology at present. [0003] In the process of implementing emergency intravascular balloon occlusion, the catheter and the balloon need to be deterministically introduced into the lower segment of the aorta. It is difficult to judge whether the implanted catheter has entered the lower aorta, but this method has high requirements on the operator and is difficult to judge...

AI Technical Summary

Problems solved by technology

[0003] In the process of implementing emergency intravascular balloon occlusion, the catheter and the balloon need to be introduced into the lower segment of the aorta with certainty. In the prior art, the way to determine the insertion position of the catheter and the balloon is through rapid ultrasound. Judging whether the implanted catheter has entered the lower aorta, but this judgment method has high requirements for the operator and is difficult to judge. Even experienced sonographers are often affected by abdominal fat and intestinal pneumatosis, etc., causing misjudgment

Another way to determine the location of the balloon is X-ray judgment, but this method is difficult to carry out under emergency conditions outside the hospital; and if the balloon is not released at the predetermined position, it will not only fail to achieve effective hemostasis, but may even cause tissue and organ damage. damage
