Needlepoint-covering member, method of assembling an injection needle with a needlepoint-covering member, and injection syringe with a needlepoint-covering member
First Claim
1. A needlepoint-covering member for covering the needlepoint of the injection needle comprising a needle having a sharp needlepoint and a needle hub provided at the end of the needle far from the needlepoint for being joined with the cylinder, comprising:
- a plate member whose end is fixed to the needle hub side and which can be bent to less than half of the axial length in the extended state in order to maintain the state before covering; and
a covering portion for covering the needlepoint when the bent plate member is extended;
wherein the plate member has a length to allow the covering portion to reach the position of the needlepoint when extended; and
is widthwise concaved toward the needle for resisting external forces that tend to remove the covering portion that covers the needlepoint from the needlepoint.

Abstract
The present invention provides a novel needlepoint-covering member in which the flow of medical procedure is not disturbed before used as an injection syringe, the tip of the injection needle is suitably protected after use of the injection needle, and the protecting member cannot be removed easily even when external forces are exerted. A plate member whose end is fixed to the needle hub side and which can be bent to less than half of the axial length in the extended state in order to maintain the state before covering, and a covering portion for covering the needlepoint when the bent plate member is extended are provided, and the plate member has a length to allow the covering portion to reach the position of the needlepoint when extended. The plate member is widthwise concaved toward the needle for resisting external forces that tend to remove the covering portion that covers the needlepoint from the needlepoint.

4. A needlepoint-covering member for covering the needlepoint of the injection needle comprising a needle having a sharp needlepoint and a needle hub provided at the end of the needle far from the needlepoint for being joined with the cylinder, comprising:
-
a plate member whose end is fixed to the needle hub side and which can be bent to less than half of the axial length in the extended state in order to maintain the state before covering; and
a covering portion for covering the needlepoint when the bent plate member is extended;
wherein the covering portion has a tubular shape for allowing the needle to pass through when the plate member is bent;
wherein the plate member has a length to allow the covering portion to reach the position of the needlepoint when extended; and
wherein the direction in which the plate member is bent by external forces that tend to remove the covering portion from the needlepoint is convex toward the needle. - View Dependent Claims (5, 6, 7, 8, 10, 12, 16, 19)
