Definitions
- a medical needle such as a hollow injection needle is used.
- the needle body after use is discarded, but if it is discarded as it is, there is a risk of accidents such as a waste worker accidentally pricking a finger or the like with the needle tip.
- a waste worker accidentally pricking a finger or the like with the needle tip.
- blood adheres and remains on the surface and inside of the needle body, there is a risk of infection due to such a sting.
- the protector described in Patent Document 1 has a plate-shaped protector body that also has a metal material force.
- the protector body includes a first part in which a first hole through which a needle body having a substantially constant outer diameter is formed, a second part in which a second hole is formed, and one end of the first part. A third portion connecting the second portion.
- This protector is configured to stop against the needle body by generating or increasing a frictional force between the inner peripheral surface of the first hole and the outer peripheral surface of the needle body when the needle tip is covered. !
- Patent Document 1 Japanese Patent Application Laid-Open No. 2004-154364
- the present invention provides:
- An elastic plate-like member made of a metal material is bent or curved and has a first portion formed with a first hole through which the needle body passes, and a proximal end from the first portion.
- a second portion formed on the side and formed with a second hole through which the needle body penetrates; a third portion connecting one end of the first portion and the second portion; From the other end of the first part to the tip side
- a protector body having a fourth portion extending;
- the distal end of the tubular portion is located between the first hole and the second hole! /.
- the metal material can generally keep the sliding resistance low, the needle body moves more smoothly in the process until the first posture force is displaced to the second posture. In wear. Further, the strength of the tubular portion can be increased, and therefore, in the second posture, the movement of the needle body can be more reliably prevented, that is, the detachment of the needle body force is more reliably prevented.
- the protector of the present invention is provided on the distal end side from the needle tip receiving portion, and when in the second posture, the needle tip attempts to protrude in the distal direction beyond the needle tip receiving portion.
- the protector 1 shown in these drawings is used by being mounted on a needle body (needle tube) 100 as an inner needle in the indwelling needle assembly 200, for example.
- Such a cover 3 is displaced (moved) integrally with the fourth part 24 and the fifth part 25 when the posture of the protector 1 is changed. Due to this displacement, the third wall part 33 and the second wall part 32 of the cover part 3 approach the needle body 100 (needle tip 101) and are positioned so as to cover the most distal portion 103 of the needle tip 101 from the distal end side. Move to. In other words, the third wall portion 33 and the second wall portion 32 are closed from the lower side in the figure with respect to the needle tip 101 and cover the most distal end portion 103 of the needle tip 101 from the distal end side.
- the side wall portion 7 is provided so as to be bent substantially 90 ° from both side portions of the inertia piece 5 and to protrude substantially downward in the drawing.
- the protector 1 is provided with a second needle tip receiving portion 4, which is provided with the first needle tip receiving portion (the third wall portion 33 and the third wall portion 33). Since it is closed prior to the second wall part 32), even if the needle tip 101 exceeds the first needle tip receiving part (the third wall part 33 and the second wall part 32), When the portion 103 abuts on the inner side of the second needle tip receiving portion 4, it is possible to reliably prevent the needle tip 101 from protruding beyond the protector 1 in the distal direction. Further, since the side wall portion 7 covers the side of the needle tip 101 on the proximal end side of the second needle tip receiving portion 4, the needle tip 101 tends to be displaced laterally (sideward) with respect to the protector 1. Even in this case, this can be prevented and it is possible to reliably prevent the needle tip 101 (the most advanced portion 103) from exceeding the second needle tip receiving portion 4.
- each part constituting the protector has any configuration that can exhibit the same function. Can be replaced. Arbitrary components may be added.
