Definitions

  • This invention relates to a capillary blood sampling device.
  • Application No. 10101/95 is directed to a one-piece moulding of the delivery system including the needle requiring disposal of the total device after a single use which, to an extent, lessens the cost effectiveness of the device, although not its effectiveness in use.
  • the present invention also offers important benefits including, the bubble up effect which enables unadulterated sampling, a recoiling arm to control accuracy, depth of penetration and reliability of sampling, and a pressure release mechanism to minimise pain.
  • the present invention also features a sterile needle, controlled delivery of lancet, enhanced design of needle tip to minimise pain, administration with one hand and a reusable delivery system.
  • the present invention provides a blood sampling device comprising a lancet delivery system comprising of a base member, a resiliently mounted recoiling arm member angularly extending from and above one end of the base member and having apertured lancet locating means at the outer end of the arm member, an aperture in the base member in alignment with said apertured lancet locating means, a lancet located within a moulded plastics material casing and adapted to be inserted and lockable in said locating means in a manner allowing removal therefrom after use, a hinged sleeve member located in said base member aperture and extending with respect to the base member, a latch member secured between the base member and said sleeve and operable to engage under an abutment on the lancet locating means to hold the device in an operable setting and whereby pressure on the said hinged sleeve member hinges the latch member out of engagement with said abutment and allows rapid movement of said recoiling arm and its lancet downwards through said hinge
  • an end of the hinged sleeve member is counterbored to provide a tapered lead- in to the sleeve which can in use cause the skin of a fmger tip or other part of the body to bulge up within the sleeve so as to bring the skin into proximity to the sharp end of the lancet.
  • the internal diameter of the hinged sleeve is within the range of 0.35 to 0.70 cm and more preferably 0.50 to 0.60 cm.
  • the pointed end of the lancet is provided with a moulded removable cover which protects the user from accidental sticking during handling and maintains a piercing point in sterile condition, said removable cover being easily twisted off just before use.
  • the encased lancet is located in the lancet locating aperture through slots engageable by protrusions on the moulded encasement of the lancet which encasement is rotated out of engagement with the slots into a releasable locking position.
  • Figure 1 is a side elevation of a blood sampling device according to one form of the invention
  • Figure 2 is an end elevation taken in the direction of the arrow 2 of Figure 1;
  • Figure 3 is a plan view taken along the line 3-3 of Figure 1;
  • Figure 4 is a sectional view taken along the line 4-4 of Figure 3;
  • Figure 5 is a part-sectional view showing the lancet locked in position in its locating means.
  • Figure 6 is an elevational view partly in section of the device cocked and ready for use.
  • the capillary blood sampling device is generally designated 5 and is preferably formed of moulded plastics material with the delivery system 6 thereof formed as a separate moulding, normally by injection moulding, from the lancet holder 7, also an injection moulding.
  • the delivery system 6 includes a base member 8 which is provided with serrations 9 acting as means to assist gripping of the system.
  • a recoiling arm member 10 is resiliency mounted at one end of base member 8 and extends over and above the base member 8 at an angle thereto, preferably 25° - 30°.
  • a sleeve member 12 Towards the end of base member 8 remote from the mounting of arm member 10 there is formed an aperture 11 in which is hingedly located a sleeve member 12 and wherein the hinge consists of an integrally moulded flexible lower part 13 of an upstanding latch member 14.
  • the sleeve member 12 preferably protrudes below the underside of the base member 8 to allow engagement therewith under pressure by a fmger or some other part of the body from which a sample is to be taken.
  • an apertured cylindrical part 15 adapted to releasably locate a lancet holder 7 in a locked condition.
  • the cylindrical part 15 is provided internally with vertically extending slots 16 engageable by diametrically extending protrusions 17 on the lancet holder 7 whereby on full insertion of the holder 7 into cylindrical part 15 and through the end thereof, the holder 7 may be rotated when the protrusions 17 can just clear the cylindrical part 15 and engage under a non-slotted part of cylindrical part 15 under a frictional pressure grip.
  • the lower part 18 of lancet holder 8 covering the sharp point 19 of the lancet 23 is joined to the lancet holder 7 by a weakened part 20 whereby on twisting lower part 18 to break away said lower part 18, the end sharp point 19 is exposed ready for use as shown in Figure 6.
  • the lower end 21 of cylindrical part 15 is provided on its outer surface with an abutment 22 engageable by the upper end of latch member 15 with arm member 10 lifted to a spring loaded position as shown in Figure 6.

Abstract

L'invention concerne un dispositif permettant de prélever du sang (5). Ce dispositif comprend un système de mise en place d'une lancette se composant d'un élément de base (8), d'un bras (10) à rappel, monté de manière élastique, et s'étendant de manière angulaire, à partir et au-dessus d'une extrémité de l'élément de base (8) et comportant un moyen à ouverture (15) assurant le positionnement de la lancette, au niveau de l'extrémité extérieure du bras (10). Une ouverture ménagée dans l'élément de base (8) est alignée sur le moyen de positionnement de la lancette (15). Une lancette (23) placée dans un support de plastique moulé (7) est adaptée pour être insérée et verrouillée dans le moyen de positionnement (15) d'où elle peut être retirée après utilisation. Un manchon articulé (12) placé dans l'ouverture de l'élément de base (8) s'étend en dessous de ce dernier. Un élément de verrouillage vertical (14) est fixé entre l'élément de base (8) et le manchon (12) et vient se mettre en prise avec une butée (22) sur l'extrémité inférieure du moyen de positionnement (15) pour maintenir le dispositif en position de fonctionnement. La pression exercée sur le dessous du manchon articulé (12) déplace l'élément de verrouillage (14) pour le dégager de la butée (22) et assure le pivotement du bras de rappel (10) et de la lancette (23) vers le bas, dans le manchon articulé (12).
