EMBRYO INCUBATOR INCORPORATING GAS CONTROL

摘要

The invention relates to an incubator having a chamber for cultivating embryos and a gas control system for maintaining a constant atmosphere in the incubating chamber. In a first aspect the invention relates to an incubator for incubating embryos, comprising an incubating chamber adapted to contain the embryos, and a gas unitary module in fluid communication with the incubating chamber comprising at least two proportional valves, a CO2 gas sensor and an O2 gas sensor, wherein the gas unitary module is adapted to receive a gas supply of N2 at one of said proportional valves and CO2 at another of said proportional valves, and control the proportional valves based on feedback from the gas sensors such that supply of N2 and CO2 to the incubation chamber is regulated to sustain a predefined level of O2 and/or CO2 in said incubating chamber.
