    摘要： A medical device for making foam includes a syringe having a plunger for dispensing a liquid from a liquid dispensing port, and a mixing chamber including a mixing chamber inlet, a mixing chamber outlet, a liquid flow channel extending between the mixing chamber inlet and the mixing chamber outlet, and a gas inlet channel that intersects with the liquid flow channel. The system has a gas cartridge containing the gas, a first gas conduit connected with the syringe, and a second gas conduit connected with the gas inlet channel. An actuator is coupled with the gas cartridge for releasing the gas into the first and second gas conduits. The released gas in the first gas conduit forces the plunger toward the liquid dispensing port for dispensing the liquid from the liquid dispensing port and into the liquid flow channel while the released gas in the second gas conduit flows into the gas inlet channel of the mixing chamber for mixing with the liquid in the liquid flow channel.
