The present invention relates to an anesthetic absorbing circle, comprising: a first common tube, providing an anesthetic gas mixture; an inspiration branch, connected to the first common tube and delivering the anesthetic gas mixture to a patient end; an expiration branch, connected to the first common tube and sending back the expired gas from the patient end to the first common tube; a second common tube, connected with the inspiration branch and the expiration branch at its first end and connected with the patient end at its second end; and a flow sensor, wherein the flow sensor is disposed in the first common tube. Thus, according to the present invention, the flow sensor can conduct bidirectional monitoring, the flow sensor is remote from patients, and water accumulation at the probe will not appear; in addition, the probe can be easily detached and disinfected at a high temperature, and can be used between adults and children.

1. An anesthetic absorbing circle, comprising: a first common tube (1), providing an anesthetic gas mixture;an inspiration branch (2), connected at the first end thereof to the first common tube (1) and delivering the anesthetic gas mixture to a patient end (5);an expiration branch (3), connected at the first end thereof to the first common tube (1) and sending back the expired gas from the patient end (5) to the first common tube (1);a second common tube (4), wherein the first end of the second common tube is connected to the second end of the inspiration branch (2) and the second end of the expiration branch (3) respectively, and the second end of the second common tube is connected to the patient end (5); anda flow sensor(15), wherein the flow sensor (15) is disposed in the first common tube (1). 2. The anesthetic absorbing circle according to claim 1, wherein a wind box (11), a gas storage pocket (12) and a mechanical/manual change-over switch (13) are disposed in the first common tube (1), wherein the wind box (11) is automatically operable to provide an anesthetic gas, the gas storage pocket (12) is manually operatable to provide an anesthetic gas, and the mechanical/manual change-over switch (13) switches between the wind box and the gas storage pocket so as to selectively communicate with the wind box (11) or the gas storage pocket (12). 3. The anesthetic absorbing circle according to claim 2, wherein a fresh air inlet (14) is disposed in the first common tube (1) for providing fresh air so as to be mixed with the anesthetic gas provided by the wind box (11) or the gas storage pocket (12) via the mechanical/manual switch (13) to form a gas mixture. 4. The anesthetic absorbing circle according to claim 2, wherein an APL valve (16) and an air exhaust orifice (17) are further disposed in the first common tube (1), wherein the pressure in the first common tube (1) is adjusted by adjusting the APL valve (16) so as to exhaust the gas in the first common tube (1) via the gas exhaust orifice (17). 5. The anesthetic absorbing circle according to claim 1, wherein an inspiration valve (21) is disposed in the inspiration branch (2) for unidirectionally allowing the gas mixture inspired by the patient end to pass. 6. The anesthetic absorbing circle according to claim 5, wherein an oxygen concentration sensor (22) is disposed in the inspiration branch (2) for detecting the oxygen concentration in the gas mixture reaching the patient end (5). 7. The anesthetic absorbing circle according to claim 1, characterized in that an expiration valve (31) is disposed in the expiration branch (3) for unidirectionally allowing the gas mixture expired from the patient end (5) to pass. 8. The anesthetic absorbing circle according to claim 7, wherein a pressure gauge (32) is disposed in the expiration branch (3) for detecting the pressure in the gas mixture expired from the patient end (5). 9. The anesthetic absorbing circle according to claim 7, wherein a carbon dioxide absorber (33) is further disposed in the inspiration branch (3) for absorbing carbon dioxide in the gas mixture.
