Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for controlling an examination table which can be displaced to put a patient in an arbitrary state.
The present invention relates to a control device suitable as a device for controlling the movement of an examination table for obstetrics and gynecology.

[0002]

2. Description of the Related Art An examination table for obstetrics and gynecology generally has a main body having a waist mat for receiving the patient's waist and a back mat for receiving the patient's back, and a main body that moves up and down to adjust the height position of the patient with respect to a doctor. A lifting mechanism that rotates the body around the vertical axis to adjust the patient's orientation with respect to the doctor, and a back mat to the lumbar mat to keep the patient in a supine position at any angle. And a tilting mechanism for tilting at an angle (for example, Japanese Patent Laid-Open No. 3-49462 and Japanese Utility Model Laid-Open No. 3-40995).

When a patient sits down on the main body during a medical examination, the main body is directed from the changing room side to the doctor side and raised to a predetermined height. Then, the back mat is tilted at a predetermined angle with respect to the waist mat to keep the patient in a supine position at an arbitrary angle. In this state, the medical examination is performed. After the examination,
The back mat is raised, the examination table is lowered, and the examination table is directed to the initial position. A command for driving the elevating mechanism, the rotating mechanism, and the tilting mechanism, a command for starting the medical examination, a command for ending the medical examination, and the like are performed using a foot switch or the like. These foot switches and the like are assembled on a common input device and are movably arranged on the floor.

During the examination, in order to avoid the patient and the doctor from directly contacting each other, the doctor enters the examination room after the patient is in a supine position and the curtain is placed between the patient and the doctor. Enter and exit the examination room before the patient is raised and before the curtain is opened. Therefore, during the examination, the input device is first operated outside the examination room prior to the actual examination, and then after the patient is in a predetermined supine position and the curtain is placed between the patient and the doctor, Moved to the examination room by the doctor or nurse, actually operated for the examination, and after the examination, before the patient is raised and before the curtain is opened, outside the examination room by the doctor or nurse. It is moved and further manipulated outside the examination room. However, in the conventional examination table control device, the input device and the examination table are connected by a long cable that enables the input device to move between the examination table in the examination room and the outside of the examination room. Since the cable is exposed on the floor, the cable hinders the movement of the input device itself, the movement of the medical examination equipment, the movement of the doctor and the movement of the nurse.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate cables that hinder the movement of the input device itself, the movement of medical examination equipment, the movement of doctors, and the movement of nurses.

During standby, the transmitting device 14 is moved to the vicinity of the entrance / exit of the examination room 22 in the passage 20. Also,
The main body 26 of the examination table 12 is directed toward the changing room and is lowered.

At the time of examination, after the patient is seated on the body 26,
The start switch is stepped on by passageway 20 by a doctor or nurse. As a result, the code signal S30 corresponding to the start command is supplied to the modulation circuit 34, and the optical signal corresponding to the start command is transmitted from the transmitter 36 to the receiving device 16 through the lower side of the curtain 18, so that the receiving device 16 , The start command is demodulated, and a signal S54 corresponding to the demodulated command is output from the terminal 56.

As a result, the main body 26 is directed from the dressing room side to the doctor side and raised to a predetermined height. Then
A back mat 26 is provided to keep the patient in a supine position at any angle.
b is tilted at a predetermined angle with respect to the waist mat 26a.

In this state, the medical examination is performed. For this reason,
The transmitting device 14 is moved from the passage 20 into the examination room 22 by the doctor or the nurse, and the doctor himself enters the examination room 22.

During the examination, arbitrary switches other than the start switch and the end switch are stepped on according to the contents of the examination. Also at this time, the signal S54 corresponding to the command input by the stepped foot switch is transmitted to the terminal 56 of the receiving device 16.
, The main body 26 of the examination table 12 is displaced.

When the examination is completed, the transmitting device 14 is moved from the examination room 22 to the side of the passage 20 by the doctor or the nurse, and the doctor himself also exits the examination room 22.

The end switch is then stepped on in the passage 20 by the doctor or nurse. As a result, the code signal S30 corresponding to the end command is supplied to the modulation circuit 34, and the optical signal corresponding to the end command is transmitted from the transmitter 36 to the receiving device 16, so that the receiving device 16 demodulates the end command. , The signal S54 corresponding to the demodulated command is output from the terminal 56.

As a result, the back mat 26b is raised, the main body 26 is lowered, and the main body 26 is directed to the initial position. Therefore, when the patient gets off the examination table 12 and changes his clothes, all the examinations for the patient are performed. Ends. The curtains 18 and 24 are opened and closed at any time.

According to the control device using the transmitting device 14 and the receiving device 16, the transmitting device and the receiving device are prevented from moving the transmitting device itself, moving the examination equipment, moving the doctor and moving the nurse. Since it is not necessary to connect with a cable, it becomes easy to move the transmitting device itself, the medical examination device, the doctor and the nurse, and it is safe.
