In the hospital, especially in obstetrics and gynecology, the examination stand or delivery stand used for the examination of the subject or the delivery of the pregnant woman has usually used an integral type for lying on the subject or the pregnant woman. Since it is difficult to adjust a checkup or delivery position, or even if it is adjusted, it is possible to use a manual operation. Thus, a checkup stand or a delivery stand is inconvenient to use and it is difficult to stably perform a checkup or a delivery of a pregnant woman.

On the other hand, the other type of conventional methods for solving the inconvenience caused when using a conventional examination stand or a delivery stand that requires such a one-piece or manual operation, that is, a variable type examination to vary the angle of lying down mechanically without going through the manual operation Stands or delivery stands are known in recent years.

However, such a conventional variable screen or delivery stand reduces the pain during delivery of the subject or pregnant woman and provides a variable adjustment function for adjusting the height or lying down angle according to the posture of the pregnant woman, Examination stand or delivery stand as a whole, the production structure is complicated, as well as increased manufacturing costs, due to the complicated structure of the operation easily occurs during the operation, there were a number of problems such as not compact in appearance.

In order to solve this problem, the "test and delivery stand" is installed in the lower portion of the connecting member connected to the foot support plate for supporting the foot of the subject, the connecting member is horizontally rotated by the rotation operation of the operating rod and the connecting member and A technique is disclosed in which the connected foot support plate is rotated with respect to the point where the operating rod is positioned to be spaced between the two feet of the subject.

However, the above technique has a problem in that the operating rod, which is the axis of rotation, is in a position close to the pelvis of the subject, and the subject has a feeling of forcibly opening the thigh by the manipulation of the operating rod to have sexual shame.

In addition, since the point of rotation becomes in line with the operating rod, in order to rotate the connecting member at an appropriate angle, the operating rod has to be rotated several times, so that there is a problem in that the feet of the subject do not open quickly.

In addition, the foot support plate connected to the connecting member is a part where the sole of the examinee is supported, and the knee joint part of the examinee has a condition to move freely, so that the subject loses reason during the delivery process and moves the knee joint when the medical staff does not follow the instructions of the medical staff. As a result, problems such as twisting the pelvis to narrow the acidity or disturbing the examination may occur.

In particular, the conventional medical examination table, such as Patent Document 1 is to rotate the horizontal axis around the position of the operating bar, the angle of the upper and lower knees of the knee bent in accordance with the rotation of the operating bar is difficult to give force to the mother during childbirth There is also a problem that occurs.
