Description
AIR EMBOLUS PREVENTING TRAP SYSTEM IN ANGIOGRAPHY
Technical Field This invention is about a system preventing an air embolus during angiography process. Facts About Technical Field
Angiography is a process used to visualize blood vessels for both diagnostic and treatment purposes. Much different liquid contrast material is given to arterial system via catheters in order to get visual results. One of the serious complications during this process is air embolus. When an air bubble enters arterial system, due to different reasons (lack of attention, connection failure, inexperience), it causes air embolus. This situation causes fatal scenarios in vital organs such as heart and brain.
To our knowledge, there is not a technology preventing an air embolus from happening. Doctors try to prevent this complication with their attention and catheter control.
A typical angiography system consists of syringe (automatic or manual), manifold and catheter. Via this line different device like stent, balloon can be transferred. Via three way tap on manifold contrast liquid, drug and saline infusion, aspiration of catheter line can be made. During these operations small air bubbles may enter catheter line. If operator can't recognize this phenomenon air bubble can reach the main vessels supporting heart and brain which leads to an air embolus.
With this invention, air bubbles prevented from entering system via angiography line which may cause an air embolus.
Summary
This invention is about a system that prevents air embolus in angiography. This trap system includes: syringe, cylindrical trunk with a wider diameter than catheter line, input tip of cylindrical trunk which connects to syringe on the syringe -catheter line, cylindrical trunk output tip on the syringe-catheter line, conical shaped disks, inside the cylindrical trunk conical shaped chambers in a row angled towards syringe which have circular hole at the center. Spaces between conical shaped chambers which trap air bubbles.

Elaborate Description of Invention
This invention is about a system that prevents air embolus in angiography. This trap system includes: syringe(l), cylindrical trunk (1) with a wider diameter than catheter(8) line, input tip (6) of cylindrical trunk(l) which connects to syringe(8) on the syringe-catheter line, cylindrical trunk (l)output tip(7) on the syringe- catheter(9) line, conical shaped disks (5) inside the cylindrical trunk(l) conical shaped chambers(4) in a row angled towards syringe(8) which have circular hole at the center.
Conical shaped disks (5) placed parallel against each other with a certain distance. Also conical shaped disks (5) feature a circular aperture with a diameter preferably wider 1-3 mm than catheter line diameter. Besides this, circular aperture at the center of conical shaped disks (5) is placed from syringe (8) tip to catheter (9) tip to make a straight, uninterrupted, circular flow line.
Compatible air trapping system includes: bubble input line from syringe that representing incoming bubbles in the liquid from syringe to cylindrical trunk.,line of escaping bubbles going upwards in cylindrical trunk that representing bubbles entering the trunk escaping from middle line to upwards, cylindrical trunk air bubbles stuck chamber representing air bubbles in cylindrical trunk stuck in cambers between conical shaped disks, line of escaping bubbles going upwards, line of sucking bubbles going upwards that representing released air bubbles.
Output tip of air trapping system (7), connects to the catheter (9) which is the last connection point of the system. Input tip (6) connects with the last part of syringe (8) system.
Preparation phase; system connection are made before the angiography operation and like many routine operations all the line is filled with saline. Before the operation air trapping system is hold as shown in the Figure 7 and saline is infused from output tip to input tip. Thus air trapping system is fully filled with saline and with the help of gravity all the air removed by sucking into syringe. While making connection with catheter, aspiration towards syringe in vertical position sucks air bubbles that made with connection and existing in catheter as seen in Figure 7.
When all the system including air trapping system is filled with saline, preparations for angiography is done. While angiography process like routine syringe is hold with a 45 degree angle. System that connected to air trapping system meanwhile can be holding horizontal. From this point if any air bubble enters the system before the air trapping system, it goes to the input tip of the air trapping system.
When liquid carrying air bubbles comes from syringe (10) to cylindrical trunk of air trapping system the velocity of the liquid decreases. Meanwhile air bubbles are removed from mid-line going upwards with the help of gravity and stuck in the chambers (4) between conical shaped disks (5) sides. Injected liquid goes to catheter without any obstacle. Air bubbles stuck according to injection speed stuck in conical shaped disks (5) sides. To remove air bubbles that are stuck in chambers (4) between conical shaped disks (5) sides, air trapping system is hold vertical again and liquid is infused towards syringe as seen in Figure 7. With the help of conical shaped disks are angled towards syringe, stuck air bubbles escapes and removed being suckedtowards syringe.
