- the present invention relates generally to blood monitoring devices, and, more particularly, to an adjustable endcap for lancing devices used to lance a finger or other areas of the body to harvest blood for monitoring.
- Those who have irregular blood glucose concentration levels are medically required to regularly self-monitor their blood glucose concentration level.
- An irregular blood glucose level can be brought on by a variety of reasons including illness such as diabetes.
- the purpose of monitoring the blood glucose concentration level is to determine the blood glucose concentration level and then to take corrective action, based upon whether the level is too high or too low, to bring the level back within a normal range.
- the failure to take corrective action can have serious implications.
- blood glucose levels drop too low a condition known as hypoglycemia—a person can become nervous, shaky, and confused. That person's judgment may become impaired and they may eventually faint.
- a person can also become very ill if their blood glucose level becomes too high—a condition known as hyperglycemia. Both conditions, hypoglycemia and hyperglycemia, are potentially life-threatening emergencies.
- One method of monitoring a person's blood glucose level is with a portable, hand-held blood glucose testing device.
- a drop of blood is obtained from the fingertip using a lancing device.
- a typical lancing device contains a needle lancet to puncture the skin.
- Some of these lancing devices have no means of adjusting the depth of penetration of the lancet.
- These lancing devices cannot accommodate different skin thicknesses which impacts the amount of blood that can be drawn. In addition, these devices cannot accommodate differences in pain tolerances of the person whose blood is being drawn.
- adjustable lancing devices Although there are adjustable lancing devices, these devices typically adjust the position of a structural element that engages a lancet holder thereby limiting the travel of the lancet. These are cumbersome to adjust and are subject to rapid deterioration. Other adjustable lancing devices have multiple parts resulting in high costs, and complicated adjustment procedures.
- the present invention is an endcap for a lancing device that adjusts the penetration depth of a lancet in a lancing device allowing the lancing device to be adjusted to accommodate skin thickness and pain tolerance of the person on whom the lancing device is used.
- the endcap contains adjustment structure and is adapted to fit on an existing lancing device thus reducing the cost.
- the endcap of the present invention consists of only two parts, a basecap and a twistcap. Because there are fewer parts than prior art adjustable lancing devices, the cost is reduced and the assembly and use of the endcap of the present invention are simplified.
- the basecap includes a central post on which the twistcap is mounted. The lancet of the lancing device when triggered, extends through the basecap, across the distance between the basecap and the twistcap, and through and beyond the twistcap.
- the end of the twistcap is the portion of the endcap that is pressed against the skin of the person from whom blood is to be drawn.
- the twistcap includes external helical tracks into which fingers on the basecap extend.
- a user merely needs to twist or rotate the twistcap and the interaction of the fingers and helical tracks moves the twistcap relative to the basecap.
- the distance the lancet of the lancing device extends beyond the basecap is constant. Therefore, by adjusting the distance between the basecap and twistcap by twisting the basecap, the distance the lancet extends out of the twistcap and into a user's finger is adjusted. Consequently, the user of a lancing device that has an endcap of the present invention can easily adjust the depth of penetration of the lancet merely by rotating or twisting the endcap.

Abstract
Description
- The present invention relates generally to blood monitoring devices, and, more particularly, to an adjustable endcap for lancing devices used to lance a finger or other areas of the body to harvest blood for monitoring.
- It is often necessary to quickly obtain a sample of blood and perform an analysis of the blood sample. One example of a need for painlessly obtaining a sample of blood is in connection with a blood glucose monitoring system where a user must frequently use the system to monitor the user's blood glucose level.
- Those who have irregular blood glucose concentration levels are medically required to regularly self-monitor their blood glucose concentration level. An irregular blood glucose level can be brought on by a variety of reasons including illness such as diabetes. The purpose of monitoring the blood glucose concentration level is to determine the blood glucose concentration level and then to take corrective action, based upon whether the level is too high or too low, to bring the level back within a normal range. The failure to take corrective action can have serious implications. When blood glucose levels drop too low—a condition known as hypoglycemia—a person can become nervous, shaky, and confused. That person's judgment may become impaired and they may eventually faint. A person can also become very ill if their blood glucose level becomes too high—a condition known as hyperglycemia. Both conditions, hypoglycemia and hyperglycemia, are potentially life-threatening emergencies.
- One method of monitoring a person's blood glucose level is with a portable, hand-held blood glucose testing device. In order to check the blood glucose level with the testing device, a drop of blood is obtained from the fingertip using a lancing device. A typical lancing device contains a needle lancet to puncture the skin. Some of these lancing devices have no means of adjusting the depth of penetration of the lancet. These lancing devices cannot accommodate different skin thicknesses which impacts the amount of blood that can be drawn. In addition, these devices cannot accommodate differences in pain tolerances of the person whose blood is being drawn.
- Although there are adjustable lancing devices, these devices typically adjust the position of a structural element that engages a lancet holder thereby limiting the travel of the lancet. These are cumbersome to adjust and are subject to rapid deterioration. Other adjustable lancing devices have multiple parts resulting in high costs, and complicated adjustment procedures.
- The present invention is an endcap for a lancing device that adjusts the penetration depth of a lancet in a lancing device allowing the lancing device to be adjusted to accommodate skin thickness and pain tolerance of the person on whom the lancing device is used. The endcap contains adjustment structure and is adapted to fit on an existing lancing device thus reducing the cost.
- The endcap of the present invention consists of only two parts, a basecap and a twistcap. Because there are fewer parts than prior art adjustable lancing devices, the cost is reduced and the assembly and use of the endcap of the present invention are simplified. The basecap includes a central post on which the twistcap is mounted. The lancet of the lancing device when triggered, extends through the basecap, across the distance between the basecap and the twistcap, and through and beyond the twistcap. The end of the twistcap is the portion of the endcap that is pressed against the skin of the person from whom blood is to be drawn. The twistcap includes external helical tracks into which fingers on the basecap extend. To adjust the endcap, a user merely needs to twist or rotate the twistcap and the interaction of the fingers and helical tracks moves the twistcap relative to the basecap. The distance the lancet of the lancing device extends beyond the basecap is constant. Therefore, by adjusting the distance between the basecap and twistcap by twisting the basecap, the distance the lancet extends out of the twistcap and into a user's finger is adjusted. Consequently, the user of a lancing device that has an endcap of the present invention can easily adjust the depth of penetration of the lancet merely by rotating or twisting the endcap. There are stops that can be felt and heard by a user as the twistcap is rotated. These stops correspond to different penetration depths and are provided by detents on the central post of the basecap and detent slots on the inside of the twistcap.
- Other objects and advantages of the invention will become apparent upon reading the following detailed description in conjunction with the drawings in which:

- Many children and adults must draw their blood several times a day to perform an analysis of the blood sample drawn. Skin thickness and tolerance to pain differs among these people and a device for lancing a person's skin to draw blood preferably includes a mechanism that allows adjustment of the depth of penetration of the lance. An example of a known
lancing device 100 is shown in FIG. 1. The knownlancing device 100 is disclosed in U.S. Pat. No. 5,954,738 and is incorporated herein in its entirety by reference. The knownlancing device 100 includes amain housing portion 112, ahousing portion 114 movable relative to themain housing portion 112 and anendcap support 116. Anend cap 118 may be attached onto theendcap support 116 by a pair of latching or supportarms 120 which are part of theendcap support 116. - A lancing mechanism including a lance is mounted inside the
main housing portion 112. The lance is driven through an opening in theendcap 118 by a driving mechanism that is cocked by pulling thehousing portion 114 away frommain housing portion 112. The driving mechanism is fired by pushing abutton 122. The knownlancing device 100 is provided with a number of different sizedendcaps 118 to vary the penetration depth of the lance. - The
lancing device 10 of the present invention is shown in FIGS. 2-7. Thelancing device 10 is the same as the knownlancing device 100 in that it includes amain housing portion 12, ahousing portion 14 that is movable relative to the main housing portion, anendcap support 16 and abutton 22 for firing a driving mechanism and lancing mechanism housed in themain housing portion 12. Thelancing device 10 differs, however, from the knownlancing device 100 in that it does not require a number of different sized endcaps to vary the penetration depth of a lance. Instead, thelancing device 10 includes anadjustable endcap 18 that can be adjusted quickly and easily for multiple lance penetration depths. - The
endcap 18 is a two piece assembly consisting of abasecap 24 and atwistcap 26. Thetwistcap 26 includes a top orface 28 that is placed on the skin of the person whose blood is to be drawn. There is an opening 30 in thetop 28 through which a lance is driven when thebutton 22 is depressed. By varying the position of the top 28 relative to thebasecap 24, the distance the lance extends out of thetwistcap 26 and thus the penetration depth of the lance can be adjusted. - To provide the lancing
device 10 with quick adjustment of the penetration depth, thebasecap 24 may be snapped onto a pair of support arms (not shown) similar to thesupport arms 120 on the known lancing device 110. As best seen in FIGS. 4 and 5, thebasecap 24 includes abody 32 with a pair ofshoulders shoulders device 10.Indicia 38 is provided on the top of thebody 32 to indicate the different penetration depths of the lance. Thebasecap 24 further includes a column or post 40 located between and spaced from theshoulders post 40 includes a top 42 with acentral opening 44 through which the lance extends. Thepost 40 also includes first 46 and second 48 cantilevered detents. A pair of protrusions orfingers shoulders post 40. - The
twistcap 26 fits over and onto the column or post 40. As best illustrated in FIGS. 3, 6 and 7, thetwistcap 26 includesseveral ribs 50 that provide a gripping surface allowing a user to grip and rotate thetwistcap 26 relative to thepost 40 and thebasecap 24. Thetwistcap 26 also includes anindicator line 52 that points to a different portion of theindicia 38 as thetwistcap 26 is rotated thereby indicating the depth of penetration of the lance at that position of thetwistcap 26. - A first
helical groove 54 and a secondhelical groove 56 are formed in the lower outside surface of thetwistcap 26. Thegrooves twistcap 26 and aligned with a protrusion orfinger respective groove twistcap 26 is placed on and over thepost 40. - As best illustrated in FIG. 7,
several slots peripheral surface 68 of thetwistcap 26. When thetwistcap 26 is placed on the column or post 40 and rotated, thedetents slots indicia 38 includes afirst symbol 38 a in the form of a large drop and asecond symbol 38 b in the form of a smaller drop. Between thefirst symbol 38 a and thesecond symbol 38 b are fivedot indicia 38 c. These dotindicia 38 c correspond to specific penetration depths varying from shallow (thosedot indicia 38 c closest to thesmall drop indicia 38 b) to deeper (thosedot indicia 38 c closest to thelarge drop indicia 38 a). A person can select the depth of penetration by twisting the twistcap to align theindicator line 52 with thedot indicia 38 c that corresponds with the preferred depth of penetration. - In addition to this visual selection of the lance penetration depth, a tactile and audible indication is also provided by the
detents slots slot dot indicia 38 c. As a user rotates thetwistcap 26 one of thedetents slots slot peripheral surface 68 of thetwistcap 26 passes over the detent. As thenext slot device 10 or to vary the pressure by which the lancingdevice 10 is pressed against a user's skin. - The penetration depth of the lance is shallower the greater the distance between the
face 28 of thetwistcap 26 and the top 42 of the column or post 40. This distance is adjusted by the interaction of the protrusions orfingers second grooves twistcap 26 is rotated, the first andsecond grooves fingers second grooves grooves protrusions twistcap 26 to move longitudinally relative to the column or post 40 thereby decreasing or increasing the distance between theface 28 of thetwistcap 28 and the top 42 of the column or post 40. Because the lance extends beyond the top 42 a fixed distance, as the distance between the top 42 and the top 28 is increased, the distance the lance extends beyond the top 28 is decreased, and as the distance between the top 42 and top 28 is decreased, the distance the lance extends beyond the top 28 and thus, the penetration depth, is increased. - While the present invention has been described with reference to one or more particular embodiments, those skilled in the art will recognize that many changes may be made thereto without departing from the spirit and scope of the present invention. Each of these embodiments and obvious variations thereof is contemplated as falling within the spirit and scope of the claimed invention, which is set forth in the following claims.
