Embodiment Construction

[0027] refer to figure 1 and a preferred (but not exclusive) embodiment of the invention, reference numeral 100 designates the overall device for dosing and regulating radiopaque agents during angiography through a cannula 50 of a known type , is fully schematically represented in the figure, since its structure and its function are not strictly relevant to the invention.

[0028] The following description, by way of example, will involve the dispensing of gas phase radiopaque agents, including carbon dioxide. It will be appreciated, however, that the same inventive principles and devices implementing it can be equally advantageously used for dispensing liquid-phase radiopaque agents, albeit without requiring major changes to the structure of the device.

[0029] The device 100 is connected to a carbon dioxide source 1 of chemical purity and adjustable pressure via a supply pipe 3 with the insertion of a supply device 2 and a suitable filter 2a arranged downstream of the supp...

Abstract

A device 100 for dosing and pressure adjusting of a radiopaque agent, and, in particular, of carbon dioxide, while performing angiography, is supplied at a predefined pressure, slightly higher with respect to the environment pressure, from a source 1, with the supplying means 2 enabled, through a supply pipe 3. The device 100 includes first dosing means 10, connected to the supply pipe 3 and aimed at withdrawing measured amounts of carbon dioxide from the source 1. A first reservoir 15 is connected to the first dosing means 10 by a first flow diverter 5, and contains a predefined amount of carbon dioxide to be supplied to an injection catheter 50. The device 100 includes also a second reservoir 25, connected to filling / draining means 6. The first reservoir 15 and second reservoir 25 have a common surface 20, soft or mobile, aimed at facilitating the gas pressure balance in the reservoirs. An output pipe 16 sets the first reservoir 15 and the injection catheter 50 in fluid communication, by means of a second flow diverter 7.

Description

technical field [0001] The invention relates to the technical field of production of devices for carrying out diagnostic measurements on the human or animal body. [0002] In particular, the invention relates to a device aimed at delivering a predetermined volume of liquid or gaseous radiopaque reagents in angiography tests. Background technique [0003] Angiography tests are known to involve injecting a radiopaque reagent into the lumen of a blood vessel (artery or vein) and recording radiological images of the area being examined. The diagnostic purpose of angiography is to measure and visualize possible structural abnormalities in the lumen of the blood vessel being examined, including narrowing (stenosis) and dilation (aneurysm) of the vessel lumen. [0004] Due to the exceptionally high spatial resolution and diagnostic sensitivity that can be achieved, this technique is widely used in cardiac and vascular patients. [0005] The radiopaque reagents mainly used consist...
