Abstract
A lancet body 15 is molded around a needle or blade, in which the inner end of the needle body which is unsharpened has an L-shape bend at the unsharpened end. The bend, when embedded in the plastic which forms the body of the lancet, secures the needle against removal. The method involves the bending substantially perpendicularly of the unsharpened end of the lancet needle or blade to be substantially perpendicular with the elongate body of the blade. The needle or blade is placed within a jig interiorly of the plastic mold. The jig includes spaced opposed clamps and a single orienting support to the bent portion of the needle. The body of the lancet is relieved in many areas to reduce material cost and has a molded tab cover eliminating a loose part such as a separate cover.
Description
- The present invention relates to lancets which are lancing devices primarily used to obtain capillary blood samples for various testing purposes, not the least of which is blood glucose in the case of diabetics where such testing may be done on a daily basis. The purpose of the lancet is to penetrate the epidermis to a sufficient depth in order to draw the necessary amount of blood needed for the test, and yet hold the penetration, scaring, and injury to the epidermis to the irreducible minimum.
- The present invention has, by way of background, various lancing devices which hold the lancet needle, cover, and carrier. One such device is manufactured for ProCare LLC, and is submitted separately in a prior art disclosure. Basically, however, the lancing device contains a sliding barrel with a trigger button and a base support for the lancet. A lancet cover is provided which threadedly surrounds the lancet as it is positioned in the barrel. At the outer end is an adjustable comfort tip with a lancet cover having numerical indicia and an arrow which, by rotation of the cover, determines the empirical depth to which the needle will penetrate.
- Virtually all hypodermic syringes have siliconized needles to aid in insertion to reduce the pain of insertion and further penetration. Therefore, it is desirable to siliconize the lancet needle. This permits the needle to be easily dislodged from the lancet body. In addition, a significant amount of plastic is employed by the prior art for such devices to attempt to secure the needle or blade against dislodgement, and protect against dimensional irregularities.
- Therefore, what is needed is a lancet in which the needle portion is firmly embedded in the plastic body, secured against rotation, secured against linear removal, and yet permits the utilization of a minimal amount of plastic, which plastic may be of an inferior grade and therefore less expensive than most lancet bodies, while still providing the sanitary and dimensional support necessary.
- The present invention derives from the molding of a lancet body around a needle or blade, in which the inner end of the needle body which is unsharpened has an L-shape bend. As a result of the L-shape bend, when embedded in the plastic which forms the body of the lancet, the needle can neither rotate nor be removed linearly. In short, the needle is permanently immobilized against movement within the body of the lancet, within the X, Y and Z directions. The method of the present invention involves the bending substantially perpendicularly of the unsharpened end of the needle or blade to be substantially perpendicular with the elongate body of the blade. The thus formed needle or blade is placed within a jig interiorly of the plastic mold which is used to form the lancet body and the cover, with the cover surrounding the entirety of the sharpened portion of the needle or blade. The jig includes spaced opposed clamps and a single orienting support to the bent portion of the needle. Also, the body of the lancet is relieved in many areas and has a molded tab cover thereby reducing the plastic used and eliminating a loose part such as a separate cover.
- In view of the foregoing it is a principal object of the present invention to provide an apparatus and method for forming a lancet in which the needle or blade is securely positioned against any dislodgement, whether by rotation, or by linear movement within the lancet body.
- A further object of the present invention is to provide such a lancet in which rotation and longitudinal dislodgement are prevented, which can accommodate a relatively low grade form of plastic and yet present in operation a dimensionally stable lancet, fully sanitary, for use with the typical user's home care kit.
- A further object of the present invention is addressed to a method of forming a lancet body and needle or blade with a cover head on a highly cost effective basis attributable to the lack of necessity for special purpose jigs to control the position of the needle or blade within the lancet body. As a result, a further objective is achieved by providing the bent leg or L-shaped end portion so that it can be precisely positioned interiorly in the mold, and the plastic body of the lancet molded around the needle or blade with the offset anchor resulting in a product which is dimensionally accurate to tolerances which are acceptable and heretofore unknown on the quantities produced for the disposable lancet market. dr
- Further objects and advantages of the present invention will become apparent as the following description proceeds, taken in conjunction with the accompanying illustrative drawings in which:
- FIG. 1 is an exploded partially perspective view of a typical home lancing device showing the lancet in a mid-portion of the figure;
- FIGS. 2A, 2B,2C, 2D, 2E, 2F and 2G, show the utilization of the device typically by the patient applying the lancet to his/her own finger;
- FIG. 3 is a perspective partially broken exploded view of the subject lancet showing the needle or blade interiorly thereof in its secured position;
- FIGS. 4A and 4B are two views of the lancet needle which is molded into the body portion of the lancet;
- FIG. 5 is a front elevation of the lancet;
- FIG. 6 is a side elevation of the lancet;
- FIG. 7 is a transverse sectional view of the lancet taken at7-7 of FIG. 5;
- FIG. 8 is a plan view, partially diagrammatic and partially broken, of the lower portion of the mold utilized to form the subject lancet;
- FIG. 9 is a transverse sectional partially diagrammatic view, in enlarged scale, taken along section line9-9 of FIG. 8; and
- FIG. 10 is yet another transverse sectional view taken from FIG. 8 at section line10-10 showing the support for the
angled base anchor 26 of theneedle 25. - In the preferred embodiment, as illustrated in FIG. 1, the
lancing device 10 is used to obtain a capillary blood sample needed for blood glucose monitoring or for other tests requiring one or two drops of blood. The adjustable comfort tip 11 on thelancing device 10 permits choosing the best depth for skin penetration. As shown, there are fivediscrete positions 12 which can be utilized by the self-user. - As shown in FIGS. 2A through 2G, the
needle cover 21 is twisted off of thelancet device 10, thenew lancet 20 is thereafter inserted into thelancet carrier 15, theneedle cover 21 is removed thereafter revealing theneedle 25, the lancet lancing device then has the comfort tip 11 placed in position. At this point, rotation of the adjustable comfort tip 11 offers a plurality of levels of skin penetration (see FIG. 2E). The user empirically determines which of these is best for his use. - The
lancing device 10 is cocked by slowly pulling theslide barrel 14 away from the lancing device cover. A click indicates audibly when the carrier is locked in position. Thereafter the end of the adjustable comfort tip is pressed against the finger, the trigger button 16 is engaged, and the lancing device needle tip sharpenedend 28 penetrates the epidermis to a point where the one or two drops of blood needed can be drawn. - Turning now to FIG. 3. which is an exploded perspective view, it can be seen that the two principle components of the lancet itself are the
body 22 and theneedle cover 21 cap which are the molded portions, and the needle orblade 25 which is the metal portion. - Important to the invention, and particularly shown in FIGS. 3, 5 and8, is the configuration of the needle or
blade 25 in which the end opposite the sharpenedend 28 has been bent at an angle with theneedle body 29. Desirably the bend is perpendicular to themain body 29. Such a bend to form ananchor 26 critical to the present invention in that, by providing the offset, once the needle is molded into the body of the lancet it cannot be mmoved longitudinally, nor can it be rotated, nor can it be moved sideways in any direction. By virture of theangled base anchor 26, the needle orblade 25 is permanently, dimensionally and sanitarily positioned inside the lancet body with the needle cover in place but removable by twisiting to dislodge, basically as described in FIG. 3 above. The method of the present invention will become more apparent as the description of thebody 22 of the lancet proceeds. As can be seen in FIGS. 5 and 6, there are four runners 30 which, in cross-section, give a cruciform appearance, as shown in FIG. 7. There twouninterrupted runner 31, and twointerrupted runners 32. Theinterrupted runners 31 are formed when the opposed prongs of a vise are positioned in place interiorly of the mold to securely engage the needle prior to injecting the plastic. In this fashion the position of the needle is ensured and when the vise elements are withdrawn from thebody 22, port are revealed which reduce the amount of plastic employed, and simultaneously permit the user to see and observe the needle interiorly of thebody 22. - While dimensions and composition materials do not form a key portion of the invention, those used in a commercial embodiment are illustrative of successful dimensions. All dimensions are in millimeters. As noticed particularly in FIGS.5, and 6 the entire lancet is 32 mm in length. The body portion is 20.7 mm, plus or minus 2 mm. The thickness dimension, taken from the tips of the runners, is 6.3 mm.
- The needle, as shown in FIGS. 4A and 4B, is 24.4 mm in length, plus or minus 2 mm. The bent leg is 1.8 mm in length taken from the far side of the body portion. As shown in FIG. 4A, there is double-bevel at the sharpened
end 28 of the needle. The material ideally employed is stainless steel 1CR18NI9. - The material employed for the plastic body is LDPE, better known as “low density polyethylene” blended with HDPE, better known as “high density polyethylene”. Virgin or reground may be used. Runners and flashing are reground and may be used exclusively or blended with virgin material.
- While dimensions are not considered critical, they illustrate the precision involved. The total overall length of the lancet, including the cover, is 32 mm. The diameter at the largest portion of the body across the top of opposed runners is 6 mm. The total diameter of the tip or cap portion is 9.4 mm, and its thickness is 3.5 mm.
- The method of the present invention involves developing a mold34 for a plurality of
needles 25 in connection with a multiple cavity mold in which the needle or blade are positioned so that the same can be an interior portion of the completedlancet 20 when the plastic is injected into the recess which surrounds the carrying portion of the bent angle needle or blade. In this connection, it will be seen in FIG. 5 that theneedle body 22 actually shows interiorly of thelancet body 20 because the support which holds the needle is surrounded by plastic, when the support is removed the needle appears. On the opposite side the needle is similarly viewed through much smaller ports. The reason for the smaller ports is that they contain a pin which clampling engages the needle on the post support of the jig interiorly of the mold to thereby firmly position the needle to be encapsulated in the plastic which is thereafter molded around the needle or blade. - Specifically as shown in FIG. 8, a multiple cavity mold34 is intended for forming the
lancet 20. As shown here there are 20 cavities, ten on each side. Specific details of two cavities are shown in the upper right corner of FIG. 8. Turning now to FIG. 9, it will be seen that a clampingassembly 40 is used to engage themain body 29 of theneedle 25. The lower jaw 41 of the clampingassembly 40 is somewhat larger than theupper jaw 42 of the same clamping assembly. Theneedle 25 is positioned on top of the lower jaw 41 prior to molding. At or about the same time, theangled base anchor 26 of theneedle 25 is positioned on top of theanchor support 44. When the upper portion of the mold is placed over the lower portion, and the plastic is injected, theneedle 25 and its components are securely held in place by the clampingassembly 40. After the plastic has sufficiently cooled, the two mold supports are removed and thelancets 20 removed from the mold. Specifically as shown in FIG. 5, it will be seen that the interruptedrunners 32 have ports which remain exposing needle body. Thevise ports 35 arelarge vise ports 36, andsmall vise ports 38. In addition, there is ananchor support port 45, viewed particularly in FIG. 5, and in which theangled base anchor 26 of theneedle 25 is exposed. This results from the withdrawal of theanchor support 44 when the upper and lower portions of the mold are separated. - Summarizing the above, the method contemplates providing a mold having a plurality of cavities which are the mirror image of the
lancet 20 to be molded. The next step in the process relates to providing clamping means, which are opposed, and which clampingly engage the needle body at spaced relationship. Finally, the step includes providing an anchor support at one end whereby the needle is not only supported on the anchor, but the anchor determines the position of the point of the needle within the molded lancet body cover. Thus, the sequencing, once the clamping means are provided within the mold, and the support means exist for the angledbase anchor portion 26 of theneedle 25, the needles are inserted in the one portion of the mold on top of their respective supports, shown here as three in number (two for theneedle body 25 and one for the angled base anchor 26). Thereafter the mold top is placed on the mold bottom, the clamping members engage theneedle 25 in fixed relationship to the cavity to be filled with plastic. Once the plastic is within the balance of the cavity, the needle is positively oriented therein in relation to the base of the needle and the runners which, in turn, control the spaced relationship of the sharpenedend 28 of the needle orblade 25 when positioned in atypical lancing device 10, such as shown in FIGS. 1 and 2A through 2G. - It will be understood that various changes in the details, materials and arrangements of parts, or method which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.
Claims (6)
1. A lancet for use with a lancing device having a body, a needle or blade positioned therein, and a needle cover, the body and needle cover being unitarily formed from plastic, characterized by:
said needle or blade having an elongate body portion, one end of which is sharpened, and the other end of which is bent at an angle substantially perpendicular to the body portion hereof;
the body portion of the plastic molded around the needle having opposed recesses, said recesses being formed by the withdrawal of opposed clamping members which secure the needle in place of the plastic mold when the plastic is formed above the needle, each opposed recesses revealing the needle body portion interiorly thereof as a result of having been previously clamped in a jig interiorly of the mold cavity from which the body of the lancet is formed.
2. A method of forming a lancet having a needle or blade within an elongate lancet body, produced in accordance with the following steps:
bending one end of said needle or blade body, and sharpening the other end to form a point;
forming a mold for the lancet body which forms a cavity complementary to the shape the lancet body including forming a cap portion to encapsulate the sharp end of the needle blade;
providing opposed clamping members at an interior portion of the mold in vise-like relationship to the lancet body of the needle or blade;
injecting plastic into the mold after the lancet body has been positioned therein; and
thereafter opening the mold and removing the lancet;
whereby the lancet is sanitarily housed within the lancet body with the needle or blade point encapsulated in the head and revealing, through the recesses in the body left by the withdrawal of the jig, opposite sides of the body on the needle or blade.
3. In the lancet according to claim 1 ,
a plurality of four runners extending along the body of the lancet;
said runners being at essentially perpendicular and dimensionally opposite distances from each other;
whereby the lancet body when secured in the lancing device can be ensured of a direct linear movement when fired by engagement of the lancing device.
4. In the lancet according to claim 3 ,
a plurality of vise ports in diametrically opposed relationship to each other and penetrating oppose runners proportioned to accommodate a vise gripping device interiorly of the mold from which the lancet is formed, said vise-like members being also proportioned when removed to leave inspection ports and weight reduction ports in the opposed runners extending to the needle from the outer edges of the runners.
5. In the lancet according to claim 2 , the plastic for forming said lancet being selected from that type of plastic known as LDPE, grades Q200, virgin or reclaimed.
6. In the lancet according to claim 3 , the plastic for forming said lancet being selected from that type of plastic known as LDPE, grades Q200, virgin or reclaimed.
