Abstract
There is provided an applicator including: a first liquid flow path through which a first liquid containing fibrinogen passes; a second liquid flow path through which a second liquid containing thrombin passes; a confluence section in which the first liquid and the second liquid merge with each other to form a mixed liquid; and a gas flow path through which a gas for jetting the mixed liquid passes. At least part of a wall portion defining the confluence section is composed of a gas-permeable membrane that is impermeable to the mixed liquid and permeable to the gas.

An applicator comprising:
- a first liquid flow path through which a first liquid containing fibrinogen passes;
- a second liquid flow path through which a second liquid containing thrombin passes;
- a confluence section in which the first liquid and the second liquid merge with each other to form a mixed liquid;
- and
- a gas flow path through which a gas for jetting the mixed liquid passes,
- wherein at least part of a wall portion defining the confluence section is composed of a gas-permeable membrane that is impermeable to the mixed liquid and permeable to the gas,
- wherein a length of the gas-permeable membrane in a direction in which the mixed liquid flows through the confluence section is 5.0 to 39.0 mm, and
- wherein a flow rate of the gas permeating through the gas-permeable membrane is 0.3 to 2.4 L/minute.
An applicator comprising:
- a first liquid flow path through which a first liquid containing fibrinogen passes;
- a second liquid flow path through which a second liquid containing thrombin passes;
- a confluence section in which the first liquid and the second liquid merge with each other to form a mixed liquid;
- a gas flow path through which a gas for jetting the mixed liquid passes, and
- wherein at least part of a wall portion defining the confluence section is composed of a gas-permeable membrane that is impermeable to the mixed liquid and permeable to the gas.
A method for applying a liquid to a patient, the method comprising:
- providing an applicator, the applicator comprising:
- a first liquid flow path through which a first liquid containing fibrinogen passes;
- a first syringe containing the first liquid fluidly connected to the first liquid flow path;
- a second liquid flow path through which a second liquid containing thrombin passes;
- a second syringe containing the second liquid fluidly connected to the second liquid flow path;
- a confluence section in which the first liquid and the second liquid merge with each other to form a mixed liquid;
- a gas flow path through which a gas for jetting the mixed liquid passes;
- conducting a first application by:
- injecting the gas into the gas flow path;
- after injecting the gas, applying a first force to the first syringe to force the first liquid into the confluence section;
- after injecting the gas, applying a second force to the first syringe to force the first liquid into the confluence section;
- mixing the first and second liquids to form a third liquid;
- and
- jetting the third liquid from the applicator by force of the gas.
