A medical needle unit with an air filter part configured to prevent air injection, the medical needle unit comprising:
- the air filter part having a built-in filter unit, both the air filter part and the built-in filter unit being configured to prevent the air injection,
- wherein the air filter part includes a filter supporting tube having a through-hole defined through a center axis therein, and the built-in filter unit disposed in the filter supporting tube,
- wherein the built-in filter unit includes:
- a first cover having a medicine injection tube coupler tube on a top thereof;
- an air injection preventing filter;
- a filter supporter;
- and
- a second cover having a medicine discharge tube on a bottom thereof, and
- wherein the air injection preventing filter and the filter supporter are sealed between the first cover and the second cover;
- a medical needle part coupled to a first end of the air filter part;
- and
- a medicine injection part coupled to a second end of the air filter part opposite to the first end to which the medical needle part is coupled, to be connected to an external medicine injector.
A medical needle unit with an air filter part configured to prevent air injection, the medical needle unit comprising:
- the air filter part,
- wherein the air filter part includes:
- a filter supporting tube having a through-hole defined through a center axis therein;
- and
- a filter unit disposed in the filter supporting tube;
- the filter unit coupled to the air filter part,
- wherein the filter unit includes:
- a first cover having a medicine injection tube coupler tube on a top thereof;
- an air injection preventing filter:
- a filter supporter;
- and
- a second cover having a medicine discharge tube on a bottom thereof, and
- wherein the air injection preventing filter and the filter supporter are sealed between the first cover and the second cover;
- a medicine injection part coupled to an end of the filter unit that is opposite to an end to which the air filter part is coupled;
