Description

  The present invention relates to a medical table such as an examination table, an operating table, a delivery table, etc. used for medical practice in obstetrics and gynecology.

  Conventionally, in obstetrics and gynecology, a medical table that supports a patient's body during delivery, examination, treatment, and the like is used. The medical table is equipped with a back plate (back) that supports the patient's torso, a torso (seat surface / waist plate) that supports the waist, and a pedestal (support, crotch) that supports the legs. The configuration in which the position can be changed as necessary makes it possible to keep the posture of the patient stable.

  A medical table called a delivery table or examination table can keep a patient in an upright position in the sitting or supine position during delivery or internal examination. There is a problem that it is difficult to keep calm for a long time.

  For example, when performing artificial insemination, it is necessary to keep the patient resting for a long time after performing the operation in the supine position with the legs raised up on the examination table. In addition, after giving birth in the supine position with the leg raised using the delivery table, it is necessary to keep the patient resting until the child is confirmed to be free of massive bleeding and becomes movable. However, on a medical table that does not have a flat and wide floor surface, the patient's posture can be changed from an open leg state to a closed leg state, but the patient remains constrained to the posture where both feet are raised, and mentally and physically. The burden is great.

  On the other hand, for example, Patent Document 1 describes a medical table including a flat mat-like lower body support portion that supports a lower body of a patient. In this medical table, the upper body support part that supports the patient's upper body and the lower body support part can be formed in a substantially horizontal state to form a substantially flat floor surface. Can move and keep calm and comfortable.
