Abstract

A puncture instrument set is constituted by a puncture instrument which includes a cylindrical body, plural puncture needles to be held in a state where the puncture needles are connected in series in an axis direction, a puncture needle cartridge for linearly arranging the plural puncture needles in the body, a stopping member for stopping the puncture needle cartridge at a predetermined position in its axis direction, and an elastic biasing member for biasing the puncture needle cartridge in one direction; and a puncture needle replacement jig that enables, after puncturing by the puncture needle, setting of the puncture needle cartridge at the puncture position as well as disposal of the used puncture needle, for a subsequent puncture operation.

Thereby, it is an object to provide a high-security puncture instrument set for puncturing the surface of a biologic body, which is provided with plural puncture needles, and is able to perform puncturing continuously by a simple operation.

Claims

1-31. -31. (canceled)

32. A puncture instrument set comprising:

a puncture instrument which is provided with a puncture needle cartridge that holds a plurality of puncture needles for puncturing the surface of a biologic body, said puncture needles being connected in series in an axis direction of the cartridge, and said puncture instrument performing puncture operation continuously; and

a puncture needle disposal instrument which performs, after puncturing by the puncture needle, setting of the puncture needle cartridge at a puncture operation start position for a next puncture operation, removal of the used puncture needle from the puncture needle cartridge, and storage of the removed puncture needle to be discarded.

33. A puncture instrument set as defined in claim 32 wherein

said puncture needle disposal instrument comprises

a disposal instrument return member for holding the used puncture needle, and removing the used puncture needle from the puncture instrument, and

a cylindrical member which can store a plurality of the removed puncture needles to be discarded.

34. A puncture instrument set as defined in claim 32 wherein

said puncture needle disposal instrument comprises

a disposal instrument return member for holding the used puncture needle, and removing the used puncture needle from the puncture instrument,

a cylindrical member which can store a plurality of the removed puncture needles to be discarded, and

a disposal box having an opening into which the cylindrical member is inserted, said disposal box being able to store the plural puncture needles to be discarded.

35. A puncture needle disposal instrument for removing, from a puncture instrument having a holding member which detachably holds a puncture needle for puncturing the surface of a biologic body, the puncture needle and discarding the same, comprising

a disposal instrument return member for holding the used puncture needle, and removing the puncture needle from the puncture instrument, and

a cylindrical member which stores a plurality of the removed puncture needles to be discarded.

36. A puncture needle disposal instrument as defined in claim 35 wherein

a front end of the cylindrical member is closed to prevent the disposal puncture needles stored in the cylindrical member from getting out of the cylindrical member.

40. A puncture needle disposal instrument as defined in claim 35 wherein

the whole or a portion of the cylindrical member is transparent.

37. A puncture needle disposal instrument for removing, from a puncture instrument having a holding member which detachably holds a puncture needle for puncturing the surface of a biologic body, the puncture needle and discarding the same, comprising

a disposal instrument return member for holding the used puncture needle, and removing the puncture needle from the puncture instrument,

a cylindrical member which stores a plurality of the removed puncture needles to be discarded, and

a disposal box having an opening into which the cylindrical member is inserted, said disposal box being able to store the plural puncture needles to be discarded.

38. A puncture needle disposal instrument as defined in claim 37 wherein said cylindrical member and said disposal box are separable from each other.

39. A puncture needle disposal instrument as defined in claim 38 further including

a means for closing the opening of the disposal box when the cylindrical member and the disposal box are separated from each other.

41. A puncture needle disposal instrument as defined in claim 37 wherein

the whole or portions of the cylindrical member and the disposal box is transparent.

42. A puncture needle disposal instrument as defined in claim 37 further including

a member for guiding the outer shape of the front end portion of the puncture instrument, at the upper surface of the opening of the disposal box.

43. A puncture needle disposal instrument as defined in claim 37 further including

a stopper for restricting the depth of insertion of the cylindrical member into the opening of the disposal box, said stopper being disposed in the vicinity of the opening of the disposal box.
