In this conventional examination table, the seat plate and the back plate are supported by the same support member, and after the patient assumes a vertical sitting position on the seat plate, the back plate is integrated with the seat plate by the support member. By tilting the patient's seat back, the patient's center of gravity is shifted from the seat board to the back board. At the same time, while the patient's body position remains in a sitting position, the patient's body position is adjusted to a horizontal position with a backward tilt. (part) close to the doctor through the curtain. The seat plate, which has been raised upward and forward of the patient's seat by tilting the back plate backwards, is then moved backward and downward relative to the tip of the back plate, and the seat plate is moved to the lower part of the patient's seat. It is configured so that it can be stored in

The sewage receptacle, which is linked to the back plate via a link mechanism, is configured to be automatically pulled out from the storage position to the pull-out position below the patient's examination as the back plate tilts backward; The sewage scattering prevention plate that stands up on the top of the sewage receptacle that is pulled out is opened and closed by an opening and closing mechanism that is linked to the back and forth movement of the seat plate. The sewage receiver pulled out to the drawer position receives the sewage used to wash the patient's examination area, and the sewage scattering prevention plate prevents the washed sewage from splashing onto the patient's seat, and also prevents the sewage under the seat from being splashed. Functions as a blindfold.

According to this lifting position 11, the first driving means 1
9 swings the first parallel link mechanism 13 relative to the lower bracket 12 about the pivot point 14a in the directions of arrows a and a'. The lower bracket 12 swings between a lying position where it is laid down almost horizontally on the rear side of the lower bracket 12 as shown in Fig. 2A, and an upright position where it is raised up to a predetermined angle forward and upward from the lying position as shown in Fig. 2B. Can be driven. At this time, since the first parallel link mechanism 13 performs a parallel movement, the placing portion 1 is moved between the lowered position shown in FIG. 2A and the raised position shown in FIG. It can be raised and lowered by parallel movement in the direction. Therefore, the seat plate 2 is raised and lowered while always maintaining a substantially horizontal state. By raising the stage 1 diagonally forward in the direction of arrow a from the lowered position to the raised position, the patient's seat (examination area) on the stage 1 can be brought closer to the doctor through the curtain. .

The sewage receiver and the sewage scattering prevention plate can be pulled out together using a movable member that can be driven by the driving means regardless of the backward tilt of the back plate, so that the patient's examination area can be cleaned during the examination. In the case of a doctor,
The sewage receiver and the sewage scattering prevention plate can be easily pulled out to the drawn-out position, and when the patient's examination area is not cleaned, the examination can be performed with the sewage receiver and the sewage scattering prevention plate stored in the storage position. Therefore, the sewage receptacle and the sewage scattering prevention plate are not always automatically pulled out in front of the seat board by moving the back plate, etc., but when in use, it is up to the doctor to drive the moving member using the driving means. The doctor's instructions (consciousness)
Based on this, the waste water receiver and waste water scattering prevention plate can be automatically and easily pulled out in front of the seat plate, and can be used depending on the doctor.

In addition, the sewage scattering prevention plate has a structure that allows it to be easily erected only by the urging means when it is pulled out to the drawer position, and the sewage scattering prevention plate is opened and closed by an opening/closing mechanism that is linked to the back and forth movement of the seat plate. It is much simpler in structure and less likely to break down.

Moreover, when the sewage scattering prevention plate is stored in the storage position, it is automatically folded almost horizontally against the biasing means, so the storage space for the sewage scattering prevention plate can be reduced, and when it is not in use. The sewage receiver and the sewage scattering prevention plate can be stored compactly under the seat board.
