A filter-integrated medicine transfer device in which a medicinal liquid channel is formed, comprising:
- a housing having an air passage that diverges from the medicinal liquid channel and is connected to outside;
- at least one hydrophobic air-passing filter disposed in the housing and disposed at a boundary between the air passage and the medicinal liquid channel;
- and
- at least one medicine transfer pipe disposed in the housing,
- wherein the at least one medicine transfer pipe includes:
- a first medicine transfer pipe having a first capillary channel constituting a portion of the medicinal liquid channel;
- and
- a second medicine transfer pipe having a second capillary channel disposed at a downstream side of the first capillary channel such that a medicinal liquid that has passed through the first capillary channel flows into the second capillary channel.
A medicinal liquid injection apparatus comprising:
- a pump configured to press a medicinal liquid;
- an extension tube in which the medicinal liquid flowing out of the pump flows by pressure applied by the pump;
- and
- a filter-integrated medicine transfer device connected to the extension tube and having a medicinal liquid channel,
- wherein the filter-integrated medicine transfer device includes:
- a housing having an air passage that diverges from the medicinal liquid channel and is connected to outside;
- at least one hydrophobic air-passing filter disposed in the housing and disposed at a boundary between the air passage and the medicinal liquid channel;
- and
- at least one medicine transfer pipe disposed in the housing,
- wherein the at least one medicine transfer pipe includes:
- a first medicine transfer pipe having a first capillary channel constituting a portion of the medicinal liquid channel;
- and
- a second medicine transfer pipe having a second capillary channel disposed at a downstream side of the first capillary channel such that the medicinal liquid that has passed through the first capillary channel flows into the second capillary channel.
