MEDICAL HOLLOW NEEDLE ASSEMBLY AND METHOD OF MANUFACTURING HOLLOW NEEDLE |
| 摘要 |
A medical hollow needle assembly includes an outer cylindrical body including a through-hole; a hollow needle having an outer peripheral surface, wherein a proximal portion of the hollow needle is disposed in the through-hole of the outer cylindrical body, and wherein the outer peripheral surface of the hollow needle has an outer reduced-diameter surface that has a smaller outer diameter than that of a more proximal portion of the outer peripheral surface of the hollow needle; and an inner cylindrical body including an insertion hole in which the hollow needle is disposed, wherein the inner cylindrical body is disposed between the hollow needle and an inner peripheral surface of the through-hole of the outer cylindrical body, and wherein the inner cylindrical body joins the outer cylindrical body and the hollow needle. |

1. A medical hollow needle assembly comprising:
an outer cylindrical body including a through-hole; a hollow needle having an outer peripheral surface, wherein a proximal portion of the hollow needle is disposed in the through-hole of the outer cylindrical body, and wherein the outer peripheral surface of the hollow needle has an outer reduced-diameter surface that has a smaller outer diameter than that of a more proximal portion of the outer peripheral surface of the hollow needle; and an inner cylindrical body including an insertion hole in which the hollow needle is disposed, wherein the inner cylindrical body is disposed between the hollow needle and an inner peripheral surface of the through-hole of the outer cylindrical body, and wherein the inner cylindrical body joins the outer cylindrical body and the hollow needle, wherein an inner peripheral surface of the insertion hole of the inner cylindrical body has an inner reduced-diameter surface that has a smaller inner diameter than that of a more proximal portion of the inner peripheral surface of the insertion hole, and wherein the inner reduced-diameter surface of the insertion hole is engaged with the outer reduced-diameter surface of the hollow needle. |
