The Purpose of our devise “Peripheral Intravenous Catheter With an internal Bi-Valvular Secure System” is to Avoid Back-flow spilling of blood or any other biological substance during the insertion of a catheter. Not only the Bi-valvular secure system is adaptable for the use in intravenous or arterial catheters but it can also be adapted to any type of Medical system catheters available in Medical practice due to its unique design, and without the need of changing the complete physical structure of the catheter. The present invention is for Medical field use and it provides a much more sterile and secure approach in reducing the risk of exposure to biological substances while at the same time reducing the risk of contamination to both the patient and the health care provider. For Purpose of of describing the full operating system of our devise, we have to reiterate that its function is based on the concept of keeping a sterilized access to any Medical System Catheter by avoiding back-flow spilling of any biological substance that could increase the risk of exposure and contamination.
Our invention is a unique valvular devise that is applicable to any medical systems catheter, it was specifically designed to avoid back flow of biological substances. The devise was first designed to be applicable to any simple peripheral line catheter with the idea of avoiding back flow spilling of blood whether be venous or arterial, but it is also a valvular design adaptable to any medical systems catheter without the advantage of not having to change the physical shape and components of any catheter. In the peripheral line catheters to which the Bi-valvular design was primitively inserted, the Bi-valvular system was adjusted perfectly into the central hub and automatically sealing the catheter by avoiding any escape, and converting the catheter into a closed system catheter with a unique Bi-valvular system that allows the easy extraction or removal of the needle or guide wire once the catheter is inserted and/or if needed the reinsertion of the needle or guide wire if manipulation and relocation of the catheter is needed. The advantage of this Bi-valvular devise is that the manipulation of the needle or guide wire will not damage the valve or impede its function. We claim the design of the valve as unique and one of its kind due to its simple composition and ability to fit and function as part of any Medical catheter system without having to change the conformity of the chosen catheter. Our devise has the ability to be integrated and built into the physical body and shape of any catheter system. It is logical to say and we are in our right to claim that this devise will only vary in size making it adaptable to any medical systems catheter applied to.
We claim the specifics of our Bi-valvular devise as a whole. The functional adaptability of the devise from its proximal structure to its distal structure work in conjunction and as mentioned in the specifications of the functional mechanism of the invention. The devise works by disengaging the accompanying needle or guide wire through removal. By extracting the needle or the guide wire once the catheter is inserted whether be a peripheral vein or arterial line, or any other medical system catheter the Bi-valvular system will close automatically creating a closed system catheter, and, with the unique ability of reinserting the needle or guide wire (considered pointy-cutting objects) without disrupting or damaging the Bi-valve and allowing the reopening and closure of the Bi-valvular system in case advanced or further manipulation or relocation of the catheter is needed. Once the needle or guide wire is extracted the catheter is inserted, the activation of the devise is through a unique sliding mechanism that is activated through an external connection. In this case we will describe the use of a two or three way stopcock or syringe in order to engage the valve. By externally connecting a two or three way stopcock or syringe to a medical system catheter, the devise located below the capping margin will seal through a plastic or silicon seal adapter allowing a two way flow from the external line into the peripheral. The connecting element of the stopcock or syringe to the capping portion of the catheter will not only seal to the plastic or silicon adapter, but it will push the adapter distally. The plastic or silicon seal adapter forms part of the proximal portion of the plastic made or stainless steal tube guide. This tube guide harbors the needle or guide wire and its from this tube guide that the needle or guide wire is extracted and reinserted. This plastic or stainless steal tube guide is surrounded in its trajectory from the base of the plastic/silicon seal adapter to the roof of the body of the silicon rubber valve by a Teflon made or stainless steal mini-spiral spring band that works as a resistance support for the tube guide during the sliding mechanism when externally activated by pushing the tube guide distally to open the valve, and in the same fashion sliding retraction of the tube guide when disengaging the valve by closing and creating a closed system catheter when the catheter is in between uses during therapeutic treatment of the patient. As the plastic or stainless steal made tube slides into the body of the silicon rubber valve, it does so through an internalized plastic tubular guide that functions as the internal skeleton of the body of the valve facilitating the slide through and opening of the Bi-valve from inside out, and in the same fashion facilitating the retracting mechanism of the tube guide to close the Bi-valve in between uses. The devise does not impede or reduce the free flow of therapeutic solutions.
