Venous Access Implantable Port

Abstract

A venous access implantable port allows a doctor or medical practitioner to use the same injection or extraction site for multiple procedures. The venous access implantable port includes a port body, a venous access orifice, a fluid reservoir, at least one fluid transport tube, and a catheter. The port body is transdermally positioned at the procedural location. The venous access orifice traverses into the port body in order to allow a needle to be inserted through the venous access orifice to extract or inject fluid into the fluid reservoir integrated into the port body. The fluid reservoir is in fluid communication with a patient's circulatory system through the catheter and the at least one fluid transport tube traversing into the port body, in order to allow the extraction or injection of fluids into the circulatory system.

DETAIL DESCRIPTIONS OF THE INVENTION

[0015] All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

[0016] The present invention is a venous access implantable port. The present invention allows for a reusable site for extracting blood samples or infusing drugs for the treatment of a patient. The present invention is transdermally positioned on a patient in order to allow a doctor or another medical professional to access the present invention efficiently, while allowing the present invention to interface with a vein of a patient's circulatory system.

[0017] In accordance to FIG. 4, the present invention comprises a port body 1, a venous access orifice 2, a fluid reservoir 3, at least one fluid transport tube 4, and a catheter 5. The port body 1 provides structure to the present invention in order to prevent the present invention from being crushed under the pressure from the surrounding skin, as the present invention is positioned transdermally during implementation. The venous access orifice 2 traverses into the port body 1, as shown in FIG. 1, FIG. 4, FIG. 5 and FIG. 8. The venous access orifice 2 allows a doctor or medical professional to insert a needle into the present invention in order to inject or extract fluids into or from the patient's circulatory system. The fluid reservoir 3 retains a quantity of fluid in order to prevent air from being introduced into the blood stream as fluid is being injected or extracted through the present invention. The fluid reservoir 3 is integrated into the port body 1, as shown in FIG. 4, FIG. 7, and FIG. 10. The venous access orifice 2 is in fluid communication with the fluid reservoir 3 in order to allow fluid to be transferred between a needle inserted through the venous access orifice 2 and the fluid reservoir 3. The at least one fluid transport tube 4 allows fluids to be transferred between the fluid reservoir 3 and the catheter 5. The at least one fluid transport tube 4 laterally traverses into the port body 1, and the at least one fluid transport tube 4 traverses into the fluid reservoir 3 from the port body 1. The catheter 5 directly interfaces with the patient's circulatory system in order to deliver or extract fluid from the patient. The catheter 5 is laterally positioned with the port body 1. The fluid reservoir 3 is in fluid communication with the catheter 5 through the at least one fluid transport tube 4 in order to allow fluid to be transferred between the patient the fluid reservoir 3.

[0018] In accordance to the preferred embodiment of the present invention, the present invention comprises an extruded cuff 6, as detailed in FIG. 1 to FIG. 4, FIG. 6, and FIG. 9. The extruded cuff 6 extends out from the patient's skin. The extruded cuff 6 allows needles to be more easily inserted to the present invention. The extruded cuff 6 is externally connected to the port body 1. The extruded cuff 6 is perimetrically positioned about the venous access orifice 2 in order to help a doctor or medical practitioner to insert a needle into the present invention.

[0019] In some embodiments of the present invention, the present invention comprises at least one septum 7, and the at least one fluid transport tube 4 is a plurality of fluid transport tubes 8 in accordance to FIG. 7 and FIG. 10. The at least one septum 7 partitions the fluid reservoir 3 into a plurality of lumina 9. The plurality of lumina 9 is a series of hollow structures for fluid delivery or extraction between a needle inserted into a lumen of the plurality of lumina 9 and the at least one fluid transport tube 4. Each of the fluid transport tubes of the plurality of transport tubes is in fluid communication with a corresponding lumen of the plurality of lumina 9 to provide multiple fluid channels to and from the catheter 5.

[0020] In a more specific embodiment of the present invention, the first lumen 10 is adjacently positioned with the second lumen 11, and the third lumen 12 is adjacently positioned with the second lumen 11, as shown in FIG. 5 and FIG. 7. The first lumen 10 is oppositely positioned with the third lumen 12 about the second lumen 11 such that the first lumen 10, the second lumen 11 and the third lumen 12 are linearly aligned to allow the doctor or medical practitioner to designate each of the first lumen 10, the second lumen 11, and the third lumen 12 for a specific purpose. In an alternate specific embodiment, the plurality of lumina 9 comprises a first lumen 10, a second lumen 11, and a third lumen 12, as shown in FIG. 8 and FIG. 10. The first lumen 10 is adjacently positioned with the second lumen 11 and the third lumen 12, and the second lumen 11 is adjacently positioned with the first lumen 10 and the third lumen 12. This configuration provides the doctor or medical practitioner with equal accessibility to the first lumen 10, the second lumen 11, and the third lumen 12.

[0021] Further in accordance to the preferred embodiment, the present invention comprises a catheter lock 13, as shown in FIG. 1 to FIG. 10. The catheter lock 13 secures the catheter 5 to the port body 1. The catheter lock 13 is externally and laterally connected to the port body 1. The catheter lock 13 is positioned about the at least one fluid transport tube 4. The catheter lock 13 is selectively engaged with the catheter 5 in order to allow the positioning procedure for the catheter 5 to be performed independent of the insertion or removal of the port body 1 into the patient's skin.

[0022] The present invention further comprises a subcutaneous tissue mounting overlay 14, in accordance to FIG. 1 and FIG. 4. The subcutaneous tissue mounting overlay 14 is a coating or covering to adhere the present invention to the subcutaneous tissue in order to retain the transdermal position of the port body 1. The subcutaneous tissue mounting overlay 14 is laterally superimposed onto the port body 1 such that the subcutaneous tissue mounting overlay 14 is able to interface with the patient's subcutaneous tissue to secure the positioning of the port body 1. The subcutaneous tissue mounting overlay 14 is preferred to be polyethylene terephthalate, also known as Darcon, to graft the present invention to the subcutaneous tissue.

[0023] Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
