Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewage receiving device for an examination table used for examinations in obstetrics and gynecology.

[0002]

2. Description of the Related Art An obstetrics and gynecology examination table is provided with a shallow box-like sewage receiver that receives sewage such as washing water at the time of examination. This type of sewage receiver is generally placed under the waist mat of the examination table so that it can be withdrawn and withdrawn in a drawer state, and is usually placed in the space below the waist mat so as not to hinder the patient from getting in and out of the examination table. It is pushed in, but it is pulled forward to catch dirty water during use.

However, below the waist mat of the examination table for obstetrics and gynecology, various mechanical parts such as a frame for supporting the waist mat and a rotating mechanism for rotating the examination table around the vertical axis are arranged. Thus, there is no large space near the waist mat that can accommodate the drawer-like sewage receiver so that it does not interfere with the patient's entry to and exit from the examination table. For this reason, in a medical examination table provided with a drawer-like sewage receiver, the sewage receiver must be arranged at a position largely separated downward from the waist mat. However, in this case, the distance from the upper surface of the waist mat to the sewage receiver increases, and sewage such as washing water cannot be received. Further, if the distance from the upper surface of the waist mat to the sewage receiver is large, the sewage drop distance increases, so the sewage that has fallen out of the sewage receiver and stains the surrounding members. In order to solve these problems, if the sewage receiver is enlarged, as mentioned above,
Since there is no space on the examination table to accommodate a large drawer-like sewage receiver so that it does not prevent the patient from getting on and off the examination pedestal, most of the sewage receiver should always project forward from the waist mat. As a result, the sewage catch prevents the patient from getting on and off the examination table and is dangerous to the patient.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to prevent the sewage receiver from being placed near the waist mat when in use so as not to prevent the patient from getting on and off the examination table when not in use.

As shown in FIG. 4, the sewage receiver 42 has a first posture in which the depth direction is vertical so as to receive sewage in the opening, and the sewage receiver 42 protrudes forward of the waist mat 18 of the examination table, and FIG.
As shown in FIG. 7, the front end portion of the waist mat 18 is selectively placed in a second posture in which the waist mat 18 extends downward with the depth direction in the front-back direction.

When the sewage receiver 42 is in the first posture, the force for rotating the posture maintaining body 58 in the clockwise direction in FIG. 4 about the axis of the rod portion 58a by the weight of the sewage receiver 42 is the posture. Since it acts on the maintenance body 58,
The sliding member 64 is pushed into the engagement hole 62, and the connecting portion 58b of the posture maintaining body 58 extends obliquely downward from the rod portion 58a. As a result, the dirty water receiver 42 is positioned at the first position with respect to the waist mat 18, and is maintained in the first posture.

When the sewage receiver 42 is in the first posture, the sewage receiver 42 is largely projected from the waist mat 18 and is closest to the waist mat 18. Therefore, the sewage is surely received by the sewage receiver 42, and scattering of the sewage is prevented. The sewage received by the sewage receiver 42 is collected in the drain port 48 and drained through a hose (not shown).

When the sewage receiver 42 is in the first position and the front end of the sewage receiver 42 is pulled up using the handle 52, the posture maintaining body 58 is drawn around the axis of the rod part 58a. At 4, the force for rotating in the counterclockwise direction acts on the posture maintaining body 58, so that the sliding member 64 is pulled out from the engaging hole 62 and then moved downward in the elongated hole 60.

As a result, the sewage receiver 42 has the sliding portion 64.
