Abstract

Abstract A lancet device for performing a pricking operation comprises a barrel (36) which is closed at one end by a finger guard plate (43) having a centrally positioned hole (42). Prior to use, the hole (42) is closed by a centrally disposed axially protruding spigot (54) found on the inside of a cap (40). In use, the cap is removed and the spigot (54) is inserted into the other end of the barrel (36) to bear against a shank 44 of a needle assembly 16 is secured to the periphery of a hole (46) in an end plate (48). A finger to be pricked is placed against the finger guard plate (43) and a thumb is placed over the cap (40). Pressure between the thumb and finger causes the spigot (54) to break the attachment between the shank of the needle and the periphery of the hole (46) to allow the needle assembly to be projected through the barrel (36) under the force exerted by a compressed spring (16). A needle (34) of the assembly projects through the hole (42) to prick the finger, before being retracted into the barrel (16) as a result of the spring (16) having overstretched itself past its null position.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 81 words
A lancet device comprising a needle assembly (10), firable biassing means (16) arranged to act on the needle assembly, characterised by a housing (20) for containing a needle (34) afforded by the said assembly and having an outlet aperture (28) through which the needle will be driven by the said biassing means when it is fired, and a stop (26) arranged to halt the needle assembly so that the needle cannot extend beyond the aperture by more than a pre-defined distance.
Claim 2
Dependent Claim 81 words
A lancet device comprising a needle assembly (10), firable biassing means (16) arranged to act on the needle assembly, characterised by a housing (20) for containing a needle (34) afforded by the said assembly and having an outlet aperture (28) through which the needle will be driven by the said biassing means when it is fired, and a stop (26) arranged to halt the needle assembly so that the needle cannot extend beyond the aperture by more than a pre-defined distance.
Claim 3
Dependent Claim 29 words
A device as claimed in Claim 1 including means (16) for automatically retracting the needle back through the aperture into the housing after it has passed through the aperture.
Claim 4
Independent Claim 32 words
A device as claimed in either preceding claim in which the firable biassing means comprises a spring which can first be stressed and then released on firing to drive the needle assembly.
Claim 5
Dependent Claim 17 words
A device as claimed in Claim 3 in which the spring is attached to the needle assembly.
Claim 6
Independent Claim 34 words
A device as claimed in any preceding claim including a closure cap (40) arranged to close the aperture before or after use of the device, and constituting means for firing the fireable biassing means.
Claim 7
Independent Claim 32 words
A device as claimed in any of the preceding claims comprising two components (12, 20; 62, 82) in relatively slideable relationship and arranged to be squeezed together to fire the biassing means.
Claim 8
Dependent Claim 23 words
A device as claimed in Claim 6 in which, when the two components are squeezed together, they stress the biassing means before firing.
Claim 9
Dependent Claim 31 words
A device as claimed in Claim 6 or Claim 7 in which firing is by breaking a seal or connection between the needle assembly and one of the two said components.
Claim 10
Independent Claim 36 words
A device as claimed in any of Claims 6 to 8 in which the two said components comprise a barrel and an actuator carrying the firable biassing means, which components are arranged to slide telescopically together.
Claim 11
Dependent Claim 23 words
A device as claimed in Claim 9 in which the two components are separate before being squeezed together to fire the biassing means.
