An esophageal thermometer having a suction function of the present invention comprises: a tube having an end which is formed in a pipe shape and sealed in a hemispherical shape or an elliptical cone shape, and provided with a plurality of suction holes which are distanced from each other at predetermined intervals around the end and penetrated inside and outside the tube； a temperature sensor provided in the tube； and a suction valve provided on the other side of the tube to suction outside air. The end of the tube has a safety cover formed on the outside thereof. The safety cover has the pipe shape in the direction of the suction valve by a predetermined length wherein the pipe shape has an end portion with one side sealed in the hemispherical shape or the elliptical cone shape, has a fusion portion by which the inner circumferential surface of the other side of the end is integrally fused with the outer circumferential surface of the tube, has a cover portion of which the inner diameter from one end of the fusion portion to the end portion of the safety cover is greater than the outer diameter of the tube, and has the thickness smaller than that of the tube. The safety cover is formed outside the end of the tube such that the suction holes do not make contact with the gastric mucous membrane even when the tube is bent in the stomach of an anesthetized patient, thereby preventing the esophagus or the gastric mucous membrane from being damaged. Moreover, air is filled in an enclosed space between the inner diameter of the cover portion of the safety cover and the outer diameter of the tube such that the safety cover absorbs shock.COPYRIGHT KIPO 2020본 발명의 흡인 기능이 있는 식도 체온 측정기는 단부가 반구형 또는 타원추형으로 밀폐되는 파이프 형상으로 구성되고 단부 부근에서 일정 간격으로 이격되고 튜브의 내외로 관통된 다수개의 흡인공이 구성되는 튜브와, 튜브 내에 구성되는 온도센서와, 튜브의 타측에 구성되어 외부 공기를 흡입하는 흡입밸브로 구성된 흡인 기능이 있는 식도 체온 측정기에 있어서, 상기 튜브의 단부는 외부에 흡입밸브의 방향으로 일정 길이로 파이프 형상으로 되고 일측이 반구형 또는 타원추형으로 밀폐되는 종단부가 구성된 파이프 형상으로 되고 타측의 내주면이 튜브의 외주면에 일체형으로 융착되는 융착부가 구성되고
