Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an obstetric examination table capable of automatically cleaning the waste funnel.

(Prior technology) A cleaning tube is provided close to the seat plate of the examination table so that it can be inserted and removed freely, and a dirt funnel is detachably attached to the bottom of the seat plate. A structure in which the washing liquid is supplied from the tank to the beak tube, the amount of this liquid is adjusted and/or opened and closed by a valve member at the tip of the beak tube, and the washed liquid is received by the waste funnel. Already known.

(Problems that the invention aims to solve) However, in conventional examination tables, there was a lack of hygiene because there was no means to automatically wash the inside of the waste funnel, and the waste funnel had to be replaced frequently. This left the inconvenience of being forced to do so.

Therefore, the object of the present invention is to provide an examination table capable of automatically cleaning the waste funnel. Also,
To provide a medical examination table which can be made compact in terms of equipment by sharing one washing liquid tank for supplying the washing liquid to the cannula.

(Means and Embodiments for Solving Problems) Generally speaking, the above object of the present invention is to provide a funnel supply system which is branched from a beak tube liquid supply pipe leading from a liquid supply pump to a beak tube and which leads to a sewage funnel. This is achieved by a configuration including a liquid conduit, a valve member that opens and closes this conduit independently or selectively of the above-mentioned beak tube liquid supply conduit, and an operating switch for this valve member. This will be explained in detail below with reference to the drawings;
The figure shows one embodiment of the liquid supply system, FIG. 5 is a diagram similar to FIG. 4 of another embodiment, and FIG. 6 is a circuit diagram of the liquid supply system. In the figure, the examination table of the present invention is equipped with a seat plate 2 that can be raised and lowered with respect to a lower base 1, and a control valve member 4 for opening and closing the washing liquid and/or adjusting the flow rate. The beak tube 3 is removably installed in the
In an obstetric examination table including a waste funnel 5 detachably installed at the lower part of the seat plate 2, and a washing liquid tank 7 which supplies liquid to the beak tube 3 by a liquid supply pump 6, A funnel liquid supply pipe 9 is branched from the beak pipe liquid supply pipe 8 leading from the liquid supply pump 6 to the beak pipe 3 and reaches the waste funnel 5, and this pipe 9 is connected independently of the pipe 8 or either The present invention is characterized in that it is provided with a valve member 10 that can be selectively opened and closed, and an operating switch 11 for the valve member 10. In FIGS. 4 and 5, the discharge pipe 52 is shown as a line diagram, but specifically, as shown in FIG.
It is shaped like a tube and has many discharge orifices (not shown) on its inner surface. 12 is a check valve, and 13 is a warmer tank. The control valve member 4 is a type of push switch, and its push operation opens and closes the control valve and adjusts the flow rate. As shown in FIG. 1, a U-shaped recess 21 is provided on the front side of the seat plate 2 to provide a necessary and sufficient receiving area for the dirt funnel 5. The beak tube 3 can be freely removed and returned to a hanger 31 attached to the front surface of the seat plate 2, as shown in FIGS. 1 to 3. In FIGS. 1 to 3, reference numeral 14 denotes a back plate which is tiltable relative to an upper base 15, and which is movable up and down relative to the lower base 1 via an elevating mechanism 16. The cleaning liquid tank 7 is provided inside a tank cover 171 shown in FIG. 18 is a medical examination unit rotatably held in the opening 15 via a horizontal arm 181;
Reference numeral 19 denotes a heel rest that is attached to the left and right sides of the seat plate 2 by rods 191 so as to be horizontally rotatable and tiltable back and forth. In FIG. 6, R1 is a relay for opening and closing the valve member 10, R2 is a relay for opening and closing the liquid supply pump 6,
E indicates a power source. The operating switch 11 may be any suitable switch that can be operated by the operator, and should be provided at a position that does not interfere with the examination work.

(Function) In the embodiment in which the pipe line 9 is opened and closed by the valve member 10 (i.e., the opening/closing solenoid valve 102) independently of the pipe line 8 as shown in FIG. 4, the operation switch 11 is opened. This makes it possible to wash the waste funnel 5 regardless of whether the liquid supply to the pipe line 8 is opened or closed, and this means that washing can be performed regardless of whether the beak tube 3 is used or not. As shown in FIG. 5, the pipe line 9 is connected to the valve member 10
(Three-way switching solenoid valve 101) selectively opens and closes the pipes 8 and 9. When fluid is being supplied to either pipe 8 or 9, the other will not be supplied. For example, when the beak pipe 3 is used It becomes impossible to wash the funnel 5, and the scope of use is narrower than that of the previous example, but in actual use, it is rare that the washing work with the beak pipe 3 and the washing work of the dirty funnel 5 are done at the same time, so it is not practical. It doesn't make things worse. In the example shown in FIG. 6 in which the timer 111 is operated by the operating switch 11, the timer 111 energizes the relay R1 for a certain period of time and the valve member 10
is operated to open and another parallel relay R2
Since the pump 6 is energized and the pump 6 is operated, this example can be used in both the embodiments shown in FIGS. From a non-restrictive point of view, it is preferable to apply the method to the example shown in FIG. Note that this is not the case if the circuit shown in FIG. 6 is changed appropriately so that the output of the timer 111 is inputted only to the relay R1. It is preferable to use a magnetic pump as the pump 6 because even if an unexpected situation occurs in which the supply cannot be made from the beak tube 3, the motor shaft will simply idle and the impeller will not rotate, thereby preventing overloading the motor. .

(Effects of the invention) As described above, the present invention allows the operator to automatically wash the filth funnel during and/or after the examination by operating the operating switch, so that the filth funnel is flushed with a separate filth funnel each time a patient changes. It becomes possible to avoid the trouble of replacing the parts or the unsanitary conditions caused by dirt remaining in the affected area of a single patient, thereby contributing to efficiency and sanitization of medical work.
