Method of setting lancing member to lancing device, lancing device, and cam mechanism

Abstract

A lancing member ( 2 ) is integrally provided with a cap ( 29 ) for covering a needle ( 21 ). Upon or after being attached to a holder ( 5 ) of a lancing device (A), the lancing member ( 2 ) is rotated relative to a cap ( 29 ) by a rotator (C). As a result, the boundary ( 28 ) between the cap ( 29 ) and the lancing member ( 2 ) is broken easily to expose the needle ( 21 ).

1 . A method of supplying a lancet and a sensor from an interior of a first housing into an interior of a second housing, the method comprising:
 temporarily attaching the first housing to the second housing for causing the lancet and the sensor together to be supported respectively on a lancet holding portion and a sensor holding portion in the interior of the second housing; and   removing the first housing from the second housing while keeping the lancet and the sensor supported on the respective holding portions in the interior of the second housing.   
     
     
         2 . The method according to  claim 1 , wherein the lancet includes a body and a needle projecting from the body, the body being formed integral with a cap covering the needle and fixed to the first housing, and
 wherein the method further comprising breaking a boundary between the cap and the body of the lancet while the first housing is held attached to the second housing, by rotating the body of the lancet relative to the cap utilizing a rotating mechanism prearranged in the second housing.   
     
     
         3 . The method according to  claim 2 , wherein the lancing holding portion is reciprocally movable in the second housing, and
 wherein the rotating mechanism comprises a cam mechanism for rotating the lancet holding portion and the body of the lancet relative to the cap utilizing a pressing force exerted when the lancet holding portion is pressed into the second housing by the lancet.   
     
     
         4 . The method according to  claim 1 , wherein the first housing is slidably fitted to an end of the second housing for temporary attachment, the lancet being pressed against the lancet holding portion to be pushed into the second housing. 
     
     
         5 . The method according to  claim 2 , wherein the rotating mechanism comprises a motor for rotating the lancet holding portion and the body of the lancet relative to the cap.
