摘要：
perfusion apparatus with reduced pressure fluctuations, and bubble trap abstract: an organ perfusion apparatus comprises a pulsatile pump and a bubble trap. the bubble trap includes a chamber having at least one liquid outlet opening, at least one gas outlet opening and at least one liquid outlet opening. the bubble trap is configured to reduce or eliminate pulsatility of the liquid flow and pressure. a minimum volume of gas is maintained in the chamber, which is sufficient to dampen flow rate and pressure fluctuations of the liquid. in particular, the volume of the chamber above the gas outlet opening is at least 0.4 liter or at least 75% of the total volume of the chamber. the bubble trap may further include a liquid level sensor, and a sampling port in a wall of the chamber. ********************************** Summary of the Summary Patent Summary: "Pressure fluctuating perfusion apparatus and bubble detector ". It is an organ perfusion apparatus comprising a pulsatile pump and a bubble detector. The bubble detector includes a chamber having at least one liquid inlet opening, at least one gas outlet opening and at least one liquid outlet opening. The bubble detector is configured to reduce or eliminate the pulsatility of liquid flow and pressure. A minimum volume of gas is maintained in the chamber, which is sufficient to dampen the flow rate and pressure fluctuations of the liquid. particularly, the chamber volume above the gas outlet port is at least 0.4 liters or at least 75% of a total chamber volume. The bubble detector may additionally include a liquid level sensor and a sampling port in a chamber wall. 23532540v1 1/1 23532540v1perfusion apparatus with reduced pressure fluctuations, and bubble trap abstract: an organ perfusion apparatus comprises a pulsatile pump and a bubble trap. the bubble trap includes a chamber having at least one liquid inlet opening, at least one gas outlet opening and at least one liquid outlet opening. the bubble trap is configured
