Abstract
The present disclosure relates to a plasma treatment apparatus and a method using the same, and more particularly, to a plasma treatment apparatus for applying, to a target object, such as a biomaterial, characteristics (e.g., removal of organic materials, crosslinking reaction, etching reaction, structural change by surface chemical reaction, sterilization effect, wettability, adhesiveness, bondability, color compatibility, surface reinforcement, modification of surface heat resistance, sterilization, removal of harmful proteins/bacteria, etc.) according to plasma treatment, and a method using the plasma treatment apparatus.
Claims13
A plasma treatment apparatus comprising:
- an accommodation unit to accommodate a container in which a target object is accommodated;
- a first electrode unit in contact with the target object;
- a second electrode unit adjacent to an outer circumferential surface of the container;
- and
- a power supply unit to apply a voltage to the target object through the first electrode unit to generate plasma in the container,
- wherein the first electrode unit comprises a contact unit configured to be electrically connected to the target object, the contact unit having a tip configured to penetrate an outer surface of the container and an air flow path for exhausting internal air from the container.
A plasma treatment apparatus comprising:
- first and second accommodation units to accommodate first and second containers in which first and second target objects are accommodated, respectively;
- an independent exhaust unit, which is connected to each of the first and second accommodation units and comprises an exhaust pump and a pump valve to exhaust internal air of the first and second containers;
- and
- first and second treatment units to apply electric power for generating plasma, respectively to the first and second containers from which the internal air is exhausted by the independent exhaust unit,
- wherein the first treatment unit comprises a first electrode unit configured to be electrically connected to the first target object and a second electrode unit electrically grounded and configured as a first needle to generate a first path exhausting internal air from the first container, and
- wherein the second treatment unit comprises a first electrode unit configured to be electrically connected to the second target object and a second electrode unit electrically grounded and configured as a second needle to generate a second path exhausting internal air from the second container.
