Definitions

• Vascular catheterism means the introduction of a catheter (tube) into a blood vessel.
• Such a device is related to an improved mechanism for the catheterism of blood vessel.
• Figure No. 1 represents:
• 05- a longitudinal section view of the device, with the numerals (1 to 1 1) indicating the respective components; a longitudinal section view of the device, with its components disconnected, with the respective identifying numerals (1 A to 11 A); top views of the device, with its components disconnected, and with the 10— respective identifying numerals (IB to 1 IB); cross section views of the device, with its identifying numerals (1C to 11C).
• 1, 1A, IB and 1C indicate the protection cover of the vascular puncture needle and flexible catheter
• 2A, 2B and 2C indicate the hollow, flexible and resistant vascular catheter, made with an extremely thin wall.
• Such a catheter wrappes the puncture needle and is fixed to the device body;
• 3A, 3B and 3C indicate the stainless steel, hollow vascular puncture needle, with beveled tip. This needle is enveloped by the flexible catheter.
• 4, 4A, 4B and 4C indicate the puncture needle supporting base, with 2 lateral grips to attach it, more securely, to the body of the device and shaped like a lever, for easy disconnection. It is hollow and connected to the hole of the
• 5A, 5B and 5C indicate the hollow region of the needle supporting base, where the blood which comes from the puncture needle is collected;
• 7, 7A, 7B and 7C indicate the body of the device. It is made of plastic of different colors. In its front tip there is the flexible and hollow catheter. In its front tip there is the flexible and hollow catheter. In its front tip
• the first is a longitudinal channel, where the puncture needle and the needle base are located - this channel communicates, in its front side, with the hole of the flexible catheter;
• the other channel is a transversal one, which connects the longitudinal channel U — with the medicine administrating tube (indicated by 10). This part also shows a wing shaped projection, through which the device is held upon the puncture;
• 9 and 9A indicate the hollow transversal channel which communicates the longitudinal channel with the medicine administrating tube
• 5- - 10 indicates the medicine administrating tube, connected to the transversal channel
• the cathete ⁇ zing process of the blood vessel is done as follows
• the hollow catheter will then communicate the intenor of the blood vessel with the longitudinal chamber, and this chamber with the transversal chamber, which is connected to the medicine administrating tube, as shown m Figure 5
• the device is left attached to the skin by a piece of adhesive 25— tape, without the puncture needle
• the device shows the exact moment when the blood vessel is punctured, indicating that the vessel was "caught", filling with blood die hollow chamber of the needle base,
• the catheter left within die blood vessel is quite flexible and does not in j ure the vessel wall, and may remain in it for several days, even with abrupt movements by the patient It is a way to administer serum and medicine by excellence, for it is not necessary to constantly puncture the patient,
• the medicine administrating tube is also flexible and easy to handle when it is 4 5 — necessary to change the serum or medicine It would be then sufficient to handle with the tube's nozzle (numeral 10), without touching the device itself,
• the needle supporting base is also anatomic in shape, for easy disconnection from the device ( Figures 3 and 4)
