PUNCTURE NEEDLE, AND METHOD AND APPARATUS FOR MANUFACTURING THE SAME |
| 摘要 |
Provided is a method for producing a puncture needle, which causes no significant pain during use such as when pierced. The method for producing the puncture needle includes the step of processing a pipe-like metallic base material having at one end a grinding surface obtained by machine work with plasma generated in an atmosphere filled with a mixed gas mainly including a main gas and a reaction gas. |

1. A method of manufacturing a puncture needle, comprising the step of processing a needle-like metallic base material, having at an end a machined surface obtained by machining, with plasma generated in an atmosphere filled with a mixed gas mainly including a main gas and a reaction gas,
wherein in the mixed gas, the partial pressure of the main gas (MGP) is 0.3 to 0.5 Pa, and the partial pressure of the reaction gas (AGP) is 0.007 to 0.05 Pa; and the main gas is argon, and the reaction gas is oxygen and nitrogen. |
