Definitions

  • the present invention relates generally to medical devices and procedures
  • The- invention more particularly relates to an end cap for use in conjunction with a lancing device that allows for the collection of an increased volume of blood or bodily fluid to be sampled.
  • a lancet having a sharp lancing tip typically is mounted, permanently or releasably, to the drive mechanism of a lancing device.
  • the drive mechanism includes one or more springs, cams, motors, or other mechanism(s) for moving the lancing tip from a retracted position shielded within a housing of the lancing device to an extended position outside of the housing for lancing the subject's skin.
  • the lancing device may also include a cocking mechanism for arming the drive mechanism, and/or a triggering mechanism for firing the device.
  • the housing of the lancing device typically includes an endcap with an opening through which the lancing tip extends in its extended position. The endcap may be releasably or permanently attached to the remainder of the housing, or can comprise an integral part of the housing.
  • the fingertips have a greater density of nerve endings than alternate lancing sites, resulting in greater pain sensation from fingertip lancing than lancing at alternate sites.
  • alternate lancing sites typically contain a lower density of capillaries or a deeper capillary bed than the fingertips, alternate lancing sites often yield insufficient sample sizes or are prone to premature closure.
  • the present invention is an endcap for a lancing device that enables collection of an increased volume of blood or other body fluid to be sampled from a lancing site of a human or animal subject.
  • the device of the present invention is suitable for use at fingertip lancing sites, but is also well suited for use at alternate lancing sites such as the forearm and/or earlobe.
  • the invention is a sampling method for increasing collected sample size of blood or other body fluid from a lancing site.
  • the present invention is an endcap for a lancing device.
  • the endcap preferably has a first end for connection to the lancing device and a second end comprising a contact face surrounding an opening for passing at least the sharp tip portion of a lancet.
  • the contact face preferably has a length substantially greater than its width, and has at least one side edge along its length.
  • the invention is an endcap for a lancing device.
  • the endcap preferably has a first end for connection to the lancing device and a second end comprising a substantially planar contact face surrounding an opening for passing at least the sharp tip portion of a lancet.
  • the contact face preferably has a length substantially greater than its width and has at least one straight side edge along its length.
  • the endcap preferably also has outwardly flared first and second sides between its first and second ends, each outwardly flared side having a gripping surface thereon.
  • the invention is a lancing device for collecting a sample of body fluid from a sampling site on the skin of a subject.
  • the lancing device preferably includes a lancet and a housing comprising an endcap, the lancet being movable between a first position within the housing and a second position wherein at least a sharp tip portion of the lancet extends through an opening in the endcap.
  • the endcap preferably has a substantially planar contact face surrounding the opening, the contact face having a length substantially greater than its width and having at least one straight side edge along its length.
  • the invention is a method of lancing skin to collect a fluid sample, the method including the steps of placing a contact face of a lancing device against a subject's skin a distance away from a lancing site, drawing the contact face along the skin toward the lancing site, and lancing the skin at the lancing site
  • FIGURE 1 shows a perspective view of an endcap for a lancing device according to an example embodiment of the present invention.
  • Ranges may be expressed herein as from “about” or “approximately” one particular value and/or to “about” or “approximately” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent "about,” it will be understood that the particular value forms another embodiment.
  • FIG. 1 shows an example embodiment of an endcap 10 for a lancing device according to the present invention.
  • the endcap 10 preferably comprises a first end 12 for releasable or permanent attachment to the housing of a lancing device. Alternatively, the endcap forms an integral part of the housing of the lancing device.
  • the endcap 10 can be adapted for use with any of a variety of standard, commercially-available or later-developed lancing devices, by appropriate configuration of coupling or attachment features of the first end 12.
  • the second end 14 of the endcap 10 preferably defines the opening 16 through which the sharp lancet tip projects in its extended position to penetrate the skin at the intended lancing site.
  • the endcap is preferably formed of an engineering or medical-grade polymer, plastic, or other material.
  • the endcap 10 preferably comprises a substantially planar contact face 20 surrounding the opening 16.
  • the contact face 20 preferably comprises a length substantially greater than its width, and defines at least one side edge, and preferably first and second side edges 22a, 22b, along its length.
  • the length of the first and second side edges 22a, 22b is at least about three-quarters of an inch (3/4"), and more preferably at least about one inch (1").
  • the ends of the contact face along its width are preferably smoothly curved or radiused, or are obliquely angled away from the side edges 22a, 22b.
  • the sides of the endcap 10 between the first and second ends 12, 14 preferably flare outwardly toward the second end 14, and define one or more recesses or gripping surfaces 30.
  • the user grips the lancing device, preferably with his or her thumb and forefinger engag ing the gripping surfaces 30a, 30b.
  • the lancing device is placed with the contact face 20 against the skin a distance (preferably about one to three inches) away from the intended lancing site.
  • a steady downward pressure is applied against the skin, and the contact face is drawn across the skin toward the lancing site.
  • the lancing device is tipped at an oblique angle relative to the skin surface, such that one of the first and second side edges 22a, 22b of the contact face 20 is pressed against the skin as the lancing device is drawn along the skin surface toward the lancing site.
  • Drawing the contact face along the skin surface directs subcutaneous blood toward the lancing site.
  • the contact face is moved into position over the intended lancing site, the contact face is placed flat against the skin and the lancing device is triggered to lance the skin at the sampling site.
  • the user optionally can again draw the contact face along the skin toward the lancing site one or more times to direct more blood toward the lancing site and assist in expressing a sufficient sample size from the wound at the lancing site.

Abstract

L'invention porte sur un embout d'autopiqueur présentant une face de contact sensiblement plane entourant l'ouverture où passe la lancette et présentant une longueur sensiblement supérieure à sa largeur et au moins un bord latéral dans le sens de la longueur. L'utilisateur place l'autopiqueur pour en amener un côté au contact de la peau à une distance de plusieurs pouces du site de prélèvement, puis traîne la face de contact sur la peau vers le site de prélèvement, puis projette la lancette pour obtenir un échantillon. On peut traîner la face de contact plusieurs fois sur la peau vers le site de prélèvement pour stimuler le flux sanguin jusqu'à obtention de la taille d'échantillon souhaitée.
