Definitions
- the present invention relates in general to hollow needles such as hypodermic needles, and pertains, more particularly to, an improved needle structure that can be used in the normal manner for fluid injection or collection, in combination with an integral skin plug retainer.
- the hypodermic needle is one of the basic tools of the medical profession and typically includes a relatively thin, straight, hollow tube that may be coupled at one end to a syringe of one type or another. The other end is usually beveled to provide a sharp point for piercing the skin.
- Some of the prior art patents address the issue of minimizing tissue coring, as well as minimizing plugging of the skin.
- the prior art does not discloses a needle structure that is constructed and arranged in combination with an integral skin plug retainer.
- U.S. Patent 5,290,267 to Zimnie ⁇ riann also describes a modified needle structure with an end section that is bent laterally and a hook-shaped curve section, with the structure allegedly to avoid the cutting of plugs during its use;
- a needle structure that has proximal and distal ends.
- This needle structure comprises a needle section that is at a more proximal end of the structure, and a skin plug retainer section at the distal end of the structure and integral with the needle section.
- the needle section is a collection needle section.
- the principle of the present invention may also be applied in connection with needles for
- the collection needle section includes a generally hollow tubular member having an external surface, an inner lumen, and a port through the tubular member so as to enable fluid flow from about the tubular member to the inner lumen for collection therefrom.
- the skin plug retainer section includes a hollow tubular piece having an external surface and an inner lumen. The hollow tubular piece is preferably beveled at its distal end so as to form a piercing point.
- a barrier wall may be provided disposed intermediate the collection needle section and the skin plug retainer section. This barrier wall assists in the retention of the skin plug and also blocks fluid flow so that it does not occur over the skin plug.
- the hollow tubular piece is cylindrically truncated so as to form a leading tip segment with the aforementioned piercing point.
- the skin plug retainer may include a retaining member in the inner lumen of the hollow tubular piece.
- This retaining member may comprise at least one internally disposed annular ridge for retaining a skin plug.
- a plurality of such annular ridges are employed.
- the annular ridges may be disposed in space parallel planes.
- the collection needle section may include a plurality of ports.
- the collection needle has a generally longitudinal axis and the port is preferably of elongated configuration extending in the direction of the longitudinal axis.
- the collection needle section maybe comprised of a plurality of such elongated ports.
- the ports may be disposed in parallel but spaced one from the next. In one embodiment four such ports are employed disposed about the structure at 90° intervals.
- the collection needle section may have a stepped portion transitioning between a smaller diameter segment more proximate to the barrier wall and a larger diameter segment more remote from the barrier wall.
- the large diameter segment is contiguous with the port segment.
- the gauge of the respective sections may be any convenient size, e.g., 22ga for the smaller diameter segment more proximate to the barrier wall and 16 ga for the larger diameter segment more remote from the barrier wall. This advantageously allows for a smaller entry point and a larger flow (i.e., in the larger diameter segment).
- the barrier wall is preferably solid so as to block fluid flow directly between the skin plug retainer section inner lumen and the collection needle section inner lumen.
- a method of injecting or collecting a fluid through the skin by means of a needle structure comprises the steps of: providing at the distal end of the needle structure a skin plug retainer section having a retaining lumen and that is integral with a more proximal fluid flow section having a lumen through which a fluid is enabled to flow; penetrating the skin with the needle structure so as to capture a skin plug at the distal end of the needle structure in the skin plug retaining section; and substantially concurrently with the step of penetrating, enabling the fluid flow through the fluid flow section lumen.
- the fluid flow occurs directly with the fluid flow section and is inhibited between the lumens of the fluid flow section and skin plug retaining section.
- the step of enabling the fluid flow includes inhibiting the fluid flow past the retained skin plug.

- FIG. 6B illustrates a cross-sectional view of a second design of a third embodiment of a needle according to the present invention.
- a collection needle embodying the principles of the present mvention. It is understood that the principles of the present invention may also be employed in connection with other types of needles, including hypodermic needles whether for the purpose of collecting a fluid or injecting a fluid.
- a skin plug retainer section with a collection needle section. The purpose is to allow for skin puncture in order to access the vein for say blood collection, but not to allow the skin or tissue plug to be transferred to the blood collection bag.
- the blood flow path is directed around the skin plug. This ensures that the flow of blood does not carry any of the skin plug material into the blood collection bag.
- the skin plug retaining portion of the collection needle allows the phlebotomist to check for the presence of the skin plug in the retaining portion of the collection needle to insure it was not, as a whole, transferred to the blood collection bag.
- the principles of the present invention are disclosed herein primarily in connection with a collection needle. However, the principles of the present invention may also be employed in connection with other types of hypodermic needles such as for penetrating various tissues to inject drugs, medicine, etc. In either case, the principles of the present invention provide for retention of the skin plug, in an integral structure, along with the enabling of fluid flow through the needle lumen.
- FIGS. 1 and 2. This describes a collection needle with an integral skin plug retainer.
- the needle structure includes a collection needle section 10 and a skin plug retainer section 20.
- the skin plug retainer section is disposed at the very distal end of the needle structure and is integral with the collection needle section 10.
- Each of the sections 10 and 20 is of cylindrical construction.
- the collection needle section 10 has an inner lumen 12.
- the skin plug retainer section 20 has an inner lumen 22.
- These lumens 12 and 22 are isolated from each other by a barrier wall 30.
- the very proximal end of section 10 may have a hub (not shown) which can either form part of or be adapted for attachment to a syringe or the like.
- the collection needle section 10 may include stepped ends 14 that separate a smaller diameter midsection 15 from larger diameter end sections 16 and 17.
- the end section 17 is the same diameter as the skin plug retainer section.
- the outer diameter of the entire may alternatively be the same throughout the length of the needle, i.e., not stepped, depending on the particular needs of the application.
- the collection needle middle section 15 has four blood flow ports 18. Also illustrated by arrows 19 is the blood flow path which is noted, does not extend into the lumen 22 but instead extends about the skin plug retainer section 20 in through the ports 18 of the collection needle section.
- retaining ribs 24 there are a plurality of retaining ribs 24. These may each be a circular rib extending slightly into the lumen 22.
- the skin plug retainer section 20 also includes a tapered end 26 forming a pointed needle end at 28.
- Various different configurations of the piercing end of the needle structure may be employed with the concepts of the present invention.
- FIG. 3 illustrates the needle structure of the present invention before skin penetration occurs.
- the needle structure is shown illustrated with the more distal position of the skin plug retainer section about to contact the skin layer 42.
- FIG. 3 also illustrates under the skin layer 42, a wall 44 of the blood vessel.
- FIG. 4 illustrates the needle structure after skin penetration. Illustrated in FIG. 4 is the skin plug at 40, having been retained by the skin plug retainer section 20 as the needle penetrates the skin. This penetration is also through the blood vessel wall 44 so that blood flow may now occur, not past the skin plug, but directly about the needle through and into the lumen 12 by way of the ports IS.
- a simplified collection needle structure that has an integral skin plug retainer. This is used to retain the skin plug upon initial penetration and yet at the same time inhibit blood flow past the skin plug but enabling blood flow directly to the collection needle section through the ports 18.
- the barrier wall 30 prevents blood flow directly from lumen 22 to lumen 12.
- Figs. 5 A and 5B illustrate another embodiment of the present invention.
- a distance "D" denotes the distance the needle must penetrate a blood vessel for proper operation.
- the present embodiment seeks to reduce this distance D so as to improve insertion comfort for a patient, to reduce risk of puncture through the vein during needle insertion, and to produce a needle form and operation which is substantially closer in design to a standard end flow needle.
- the needle structure includes a collection needle section 110 and a skin plug retainer section 120.
- the skin plug retainer section is disposed at the very distal end of the needle structure and is integral with the collection needle section 1 10.
- Port 1 IS is positioned adjacent a barrier wall 130, in an effort to minimize distance D.
- Skin plug retaining ribs 124 may also be included Similarly, as shown in Fig. 5B, port 118 is positioned immediately adjacent side 131 of barrier wall 130, thus, further lessening distance D.
- the positioning of the barrier wall as illustrated in Figs. 5 A and 5B decreases the insertion distance D, so that insertion comfort to the patient is enhanced, and the risk of vein puncture is reduced.
- Figs. 6A and 6B illustrate yet another embodiment of the present invention, which is directed to cutting a clean skin plug so as to also reduce insertion distance D.
- the beveled end 220 of the needle 210 uses multiple and/or an all-around cutting edge. As a result, insertion distance D is reduced since the beveled end need not have a dramatic bevel.
