Abstract
A medical needle includes a needle portion (10) having a needle tip on a distal end, a case (30) configured to be capable of accommodating the needle portion that can be exposed from the distal end side, a movement mechanism (50) for moving the needle portion inside the case, and a movement restricting portion (37) that restricts the needle tip accommodated in the case from moving in a direction opposite to a moving direction of the needle portion. The movement restricting portion maintains the needle tip accommodated in the case such that the needle tip can come into contact with an inner face of the case to restrict the movement of the needle tip in the opposite direction.
Claims4
A medical needle comprising:
- a needle portion having a needle tip on a distal end;
- a case configured to be capable of exposing the needle portion to the distal end side and accommodating the needle portion;
- a movement mechanism for moving the needle portion inside the case until the needle tip protruding from the case is accommodated in the case;
- and
- a movement restricting portion that restricts the needle tip accommodated in the case from moving in a direction opposite to a moving direction of the needle portion by the movement mechanism, wherein
- the movement restricting portion maintains the needle tip accommodated in the case such that the needle tip can come into contact with an inner face of the case, to restrict movement of the needle tip in the opposite direction.

- and
- a movement restricting portion that restricts the needle tip accommodated in the case from moving in a direction opposite to a moving direction of the needle portion by the movement mechanism, wherein
- the case includes a base portion having a hole portion through which the needle tip can pass, and a cover portion for closing an opening on an opposite side to the hole portion of the base portion, and
- the movement restricting portion engages a part of at least either the movement mechanism and the needle portion with an engaged part of the cover portion to restrict the movement of the needle tip in the opposite direction.
