The invention provides a catheter for cervical examination, comprising: a hollow catheter (30), which is inserted into the vagina (10); a volume expansion part (70), which is arranged at one end of the catheter, and includes a A monitoring hollow portion for monitoring the cervix (20) upon volume expansion; and a volume control portion (100) configured to expand the volume of the volume expansion portion (70). The present invention also provides a detector for cervical inspection, comprising: the catheter for cervical inspection; and a cervical detection part (50) configured through the catheter. By the catheter and detector for cervical examination of the present invention, the discomfort and pain of obstetrical patients can be eliminated, and the cervix can be effectively inspected only by opening the lower part of the vagina at the front end of the cervix without opening the upper part of the vagina and the entrance of the vagina . In addition, it is possible to accurately and continuously grasp changes in the cervix of a parturient in labor without endoscopic examination, and it is possible to more objectively and accurately determine whether a caesarean section is necessary. In addition, the biofeedback effect can be expected because the pregnant woman directly confirms the changes of her cervix through the monitor. Also, since the state of the cervix in patients with early labor or early rupture of membranes before labor can be accurately confirmed, more accurate diagnosis can be made and the chance of infection can be reduced. In addition, in outpatient treatment, obstetrics and gynecology examinations are performed without using a speculum, and the state of the cervix can be directly shown and explained to the patient, thereby improving patient satisfaction.
