The present invention provides a gas absorbing system which comprises: an inlet pipe, a gas accommodating section into which gas enters through the inlet pipe, and a negative pressure exhausting pipe which exhausts the gas in the gas accommodating section to external device by using negative pressure wherein the gas accommodating section comprises a first chamber which is provided with air holes in the side wall for discharging the gas in the gas accommodating section or allowing external air entering the gas accommodating section. The gas absorbing system according to the present invention not only can effectively prevent the system internal gas from discharging directly to environment to endanger the health of patients and medical care personnel, but also can reduce the variation of the pressure inside the system when an abnormal incident occurs, so as to prevent it from influencing the safety of the patient to the most extent.

1. A gas absorbing system comprising: an inlet pipe;a gas accommodating section into which gas enters through the inlet pipe; anda negative pressure exhausting pipe which exhausts the gas in the accommodating section to an external device by using negative pressure, characterized in that, the gas accommodating section comprises a first chamber which is provided with air holes in its side wall, wherein the air holes are in direct air communication with the exterior of said gas absorbing system without passing through the negative pressure exhausting pipe such that gas in the gas accommodating section can be exhausted through the air holes to the exterior or that external air in the exterior can enter through the air holes into the gas accommodating section. 2. The gas absorbing system according to claim 1, wherein the air holes are disposed in the lower side wall of the first chamber. 3. The gas absorbing system according to claim 1, wherein the gas accommodating section further comprises a second chamber which is housed in the first chamber and communicated with the first chamber through its opened bottom, the inlet pipe passes through the side wall of the second chamber to direct the gas to into the second chamber, and the negative pressure exhausting pipe is communicated with the top of the second chamber such that the gas in the gas accommodating section is discharged from the negative pressure exhausting pipe via the top. 4. The gas absorbing system according to claim 3, wherein the air holes are disposed in the upper side wall of the first chamber. 5. The gas absorbing system according to claim 3, wherein the gas absorbing system further comprises a stop valve which is interposed between the gas accommodating section and the negative pressure exhausting pipe for controlling the flow rate of the gas exhausted from the negative pressure exhausting pipe. 6. The gas absorbing system according to claim 3, wherein the exit of the inlet pipe is facing to the bottom of the first chamber to direct the gas from the inlet pipe toward the bottom. 7. The gas absorbing system according to claim 3, wherein the second chamber extends downward to close to the bottom of the first chamber. 8. The gas absorbing system according to claim 7, wherein the opened bottom of the second chamber is spaced from the bottom of the first chamber by 20-30 mm. 9. The gas absorbing system according to claim 1, wherein the gas absorbing system further comprises a stop valve which is interposed between the gas accommodating section and the negative pressure exhausting pipe for controlling the flow rate of the gas exhausted from the negative pressure exhausting pipe. 10. The gas absorbing system according to claim 9, wherein the gas absorbing system further comprises a floater which in interposed between the gas accommodating section and the stop valve and whose up and down floating is used for adjusting the magnitude relationship between the flow rate of the gas entering the inlet pipe and that of the gas exhausted from the negative pressure exhausting pipe, so as to adjust the stop valve and thus control the flow rate of the gas exhausted from the negative pressure exhausting pipe. 11. The gas absorbing system according to claim 10, wherein the floater is accommodated in a floater chamber made of transparent material and air-tightly connected to the gas accommodating section. 12. The gas absorbing system according to claim 1, wherein the exit of the inlet pipe is facing to the bottom of the first chamber to direct the gas from the inlet pipe toward the bottom.
