<P>PROBLEM TO BE SOLVED: To provide an accidental sticking prevention instrument suitable for the structure of a pencil point needle. <P>SOLUTION: A resin guide body 20 consisting of a column section 22 and a cone section 24 and penetrating a needle through-hole 26 in the center of axle is formed; a metal holder 30 is formed in which the distal end of a pawl splinter 35 extending from a cylindrical section 34 to the tip direction is coaxially aligned to shut together, and in which a stopper piece 36 is made in the condition extending from the cylindrical section 34 to the tip direction similarly, and being inclined toward the axis, and in which a head 36a is bent as a chevron shape from the distal end position of the pawl splinter 35 to the tip direction; and a resin case body 40 consisting of a cylindrical side wall section 42 in which the cylindrical section 34 is intruded and a bottom wall 44 in which a needle through-hole 43 is opened at the center thereof. The accidental sticking prevention instrument is locked as follows. The resin guide body 20 is intruded in the metal holder 30, this is covered with the resin case body 40 to be assembled, disposed to the pencil point needle, and after the use of the pencil point needle, is moved to the needle tip, and the distal end of the pawl splinter 35 is absorbed in an opening 14. <P>COPYRIGHT: (C)2013,JPO&INPIT |
