Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is used in obstetrics and gynecology, urology, proctology, etc., in order to examine the affected area of a patient. This invention relates to an improvement in an obstetrics and gynecology examination table that allows the patient to sit on the table and open their legs.

[Conventional technology]

An example of a conventional obstetrics and gynecology examination table is shown in FIG. 7 and will be described below.

This obstetrics and gynecology examination table has a lifting table 31 that goes up and down.
A seat 32 is fixed on top, and a backrest 33
is installed so that it can rise and fall freely.

Further, the lifting table 31 is provided with an attachment part 34 for attaching a crotch support that supports the patient's crotch by expanding it, and below the seat 32 is a waste case for storing gauze, sewage used for washing the affected area, etc. 35 can be installed.

This examination table allows the patient to sit on the seat 32 with the affected area, spread and raise the crotch, and support it with the crotch support, then fold back the backrest 33 to make the patient lie on his back, and examine the affected area of the patient. The filth and sewage generated at that time are stored in the filth case 35.

[Problem that the invention seeks to solve]

The conventional examination table is configured as described above, but when the patient is seated on the seat 32, the backrest portion 33
If the patient simply lies down, the sheet 32 is located under the patient's buttocks, which not only makes it difficult to perform an examination, but also stains the sewage sheet 32 with filth.

Therefore, after the backrest part 33 is laid down, the patient must be moved forward until the patient's buttocks are located in front of the seat 32, but since the patient's lower legs are supported by the crotch supports, the forward movement is extremely difficult. It is difficult to

Therefore, it becomes necessary for the nurse to help the patient move forward, which requires time and effort, and this movement is extremely painful, especially for the elderly and those in the final stages of pregnancy.

Furthermore, when the patient sits on or gets off the seat 32 of the examination table, the dirt case 35 becomes an obstacle.

In addition, the slippers etc. that the patient takes off when climbing on the examination table get in the way during the examination, and if these are moved, it becomes necessary to put the slippers in order when the patient gets off the examination table. There is.

[Means for solving problems]

The present invention is intended to solve the above-mentioned problems of conventional obstetrics and gynecology examination tables.It eliminates the difficult movement of the patient moving forward with his or her lower limbs resting on the crotch support, and also eliminates the problem of dirt on the retracted seat. The purpose of this system is to prevent the patient's buttocks from getting dirty and getting dirty, and to eliminate the discomfort of the patient's buttocks resting on the soiled seat when they return to a sitting position. a backrest that can be raised and lowered integrally with the backrest, a raising and lowering means that raises and lowers the backrest and the seat, and a seat that can be displaced between the recesses of the seat and behind the seat;
An obstetrics and gynecology examination table equipped with a displacement means for displacing the seat, and a cover that hangs down from the front of the seat when the seat is displaced to the rear of the seat due to the operation of the displacement means. I am treated well.

[Effect]

The obstetrics and gynecology examination table of the present invention allows the patient to sit with their buttocks on the seat and with their lower legs supported by the crotch support, and after having the patient lie down with the back rest prone, the seat is placed on the buttocks. evacuate from below to the rear of the seat and assume the examination position.

In conjunction with this backward retraction of the sheet, a cover hangs down from the front of the retracted sheet to prevent the sheet from being soiled by droplets of patient's filth falling into the filth case.

Therefore, when the patient returns to a sitting position and rests his buttocks on the seat, the buttocks are not stained or the patient does not feel uncomfortable, such as feeling cold.

〔Example〕

Next, an example of implementation of the obstetrics and gynecology examination table of the present invention will be described below with reference to FIGS. 1 to 4.

Reference numeral 1 denotes a base, and on its lower surface, an adjuster 2 that moves up and down by rotation and casters 3 for movement are provided at several places.By raising the adjuster 2 and rolling the casters 3, the base can be moved. 1 can be moved.

Then, by lowering the adjuster 2, the caster 3 is separated from the floor surface, the base 1 can be fixed in that position, and the height of each adjuster 2 can be adjusted to prevent the base 1 from wobbling or tilting.

A rotating body 5 is attached to the base 1 by a thrust bearing 6 so as to be rotatable in the horizontal direction.
A gear 4 is attached to the rotating body 5, and a rack 19 attached to a ram of a rotating cylinder 18 and a rack 20 attached to a ram of a rotating cylinder (not shown) mesh with each other.

The stroke of the rotating cylinder (not shown) is half the stroke of the rotating cylinder 18.

Therefore, when the rotation cylinder 18 operates and the rack 19 moves, the gear 4 rotates 180 degrees, but when the rotation cylinder (not shown) operates, the gear 4 is rotated by the rack 20. Rotate 90 degrees.

A lifting cylinder 11 and a cover 8 are attached to the rotating body 5 via a mounting base 7 or the like, and the lifting cylinder 11 is attached to the ram of the lifting cylinder 11.
An elevating outer cylinder 9 is attached which has rollers 10 that roll along and guide the elevating and lowering.

Therefore, when the lifting cylinder 11 operates, the roller 10 rolls on its outer peripheral surface, and the lifting outer cylinder 9 moves up and down.

The upper surface of the elevating outer cylinder 9 has a backrest 15 as a fulcrum C.
A tilting cylinder 13 is mounted between a fulcrum B of the backrest portion 15 and a fulcrum A of the elevating outer cylinder 9.

Now, when the tilting cylinder 13 is in the extended state, the backrest portion 15 is in the upright state due to the fulcrum B, but when the tilting cylinder 13 is in the contracted state, the fulcrum B is
B', and the backrest 15 falls backward as shown by the dashed line in FIG.

An auxiliary seat 16 is fixed to the lower end of the backrest portion 15.

In addition, four guide rollers 21 are provided on the backrest portion 15.
is rotatably attached, and an arc-shaped slide bar L, which pivots the seat 17 at a fulcrum I, is supported by the guide roller 21 so as to be movable back and forth.

An extrusion cylinder 14 is installed between the fulcrum E of the slide bar L and the fulcrum D of the backrest portion 15,
When the extrusion cylinder 14 is in the extended state,
Since the slide bar L is moved forward, the seat 1, which is pivoted to the slide bar L at a fulcrum I,
7 moves forward and downward of the backrest portion 15.

A protrusion 17b with one side as a hypotenuse 17a is protruded from the lower surface of the seat 17, and a protrusion 15a is protruded from the backrest 15, so that the seat 17 can be positioned in front of the backrest 15 as described above. When in the lower position, the protruding portion 17b rides on the protruding rod 15a, and the backrest portion 15
It is close to the lower front of the.

When the extrusion cylinder 14 is in the contracted state,
The slide bar L attempts to move rearward while being guided by the guide roller 21 with the fulcrum E being pulled.

Then, since the seat 17 also tries to move rearward, the protruding part 17b tends to shift backward from the position of the protruding rod 15a, so that the oblique side 17 of the protruding part 17b
a slides down the protrusion 15a as shown by the two-dot chain line in FIG. 3, and the seat 17 separates downward from the backrest 15.

Further, the rearward movement of the slide bar L continues, and the seat 17 is pulled below the auxiliary seat 16 as shown by the dashed line in the figure.

On the other hand, when the extrusion cylinder 14 extends, the oblique side 17a is guided by the protrusion 15a, and the sheet 1
When seat 7 is in the most advanced position, seat 17
is raised, and the seat 17 approaches the lower front of the backrest 15. Note that, as described above, the displacement means for moving the sheet 17 includes at least the extrusion cylinder 14, the slide bar L, and the guide roller 21.
Consists of.

A cover 23, which is biased by a spring 22, is pivotally attached to the backrest portion 15 at a fulcrum P, and when the slide bar L is moving forward as described above, the cover 23 is attached to the seat. 17. It is tilted forward by the pressure of the slide bar L against the bias of the spring 22.

However, when the slide bar L retreats, the pressure on the cover 23 is removed, and the spring 22 biases the slide bar L into an upright state as shown by the dashed line in FIG. 3, covering the front surface of the seat 17 that has retreated.

Furthermore, a fixed base 24 for attaching a dirt case 27 is pivotally attached to the backrest portion 15 at a fulcrum H, and a link 25 is mounted between the fulcrum G of the arm 24a and the fulcrum F of the bracket 12. ing.

Therefore, even if the backrest portion 15 is raised and lowered as described above, the fixed base 24 is always kept horizontal due to the relationship between the fulcrums G and F.

Since this examination table has the above-described configuration, the tilting cylinder 13 is in the extended state and the backrest portion 15 is
is placed in an upright position, the extrusion cylinder 14 is extended, and the seat 17 is brought close to the lower front of the backrest 15, so that the patient can sit on the seat 17.

At this time, the cover 23 is tilted forward and the fixing base 24
is below the auxiliary sheet 16 while maintaining its horizontal position.

After the patient is seated on the seat 17 in this state, the rotating cylinder 18 or a rotating cylinder (not shown) is operated to rotate the rotating body 5 by 90 degrees or
Rotate 180 degrees so that the patient and doctor face each other.

Next, the tilting cylinder 13 is operated to tilt the backrest 15 backward, but at this time, the patient's lower limbs are attached to the crotch supports attached to the backrest 15 as shown in FIGS. 1 and 2. I'll put it on the 26th.

By tilting the backrest portion 15 backward,
The patient assumes a supine posture, and then the extrusion cylinder 14 is operated to retract the slide bar L rearward.

Then, the sheet 17 has the protruding portion 17b aligned with the protruding rod 15.
By coming off from a, the patient's buttocks in the supine position will be in a floating state because the patient's buttocks in the supine position will be in a floating state because the patient's buttocks in the supine position will be in a floating state because the patient's buttocks in the supine position will be in a floating state because the patient's buttocks in the supine position will be in a floating state.
This is the posture for receiving a checkup or medical treatment.

At this time, the fixing table 24 is located below the front of the auxiliary seat 16 and maintains a horizontal state, so if the waste case 27 is attached to this, it can receive the dirty water used in medical treatment, etc.

Further, since the cover 23 stands up on the front surface of the seat 17, splashes from the dirt case 27 can be prevented from being applied to the seat 17.

The patient's height is adjusted by raising and lowering the elevating outer cylinder 9, and examinations and medical treatment are performed.

In this way, after the patient's examination or medical treatment is completed, the push-out cylinder 14 moves in the opposite direction to support the patient's buttocks with the seat 17, and then the tilting cylinder 13 moves in the opposite direction to support the patient's buttocks. Raise the patient and return the patient to a sitting position.

At this time, even if the wastewater tray 27 is not removed from the fixed base 24, the fixed base 24 always maintains a horizontal position, so that the wastewater will not spill from the waste case 27, and the patient will be protected by the advancement of the seat 17. The dirt case 27 does not interfere with getting off or getting on the seat 17.

Next, an example of a medical room equipped with this examination table will be described with reference to FIG.

This medical room is divided by a curtain 51 into a patient's dressing room 52 and a doctor's medical room 53.

As shown in FIG. 2, the curtain 51 is
The lower part of the central part is open to the left and right, and the examination table is located close to the central part of the curtain 51 in the changing room 5.
It is located within 2.

Then, the sheet 17 is installed so as to face opposite to the curtain 51 and to the left by the rotation of the rotating body 5.

Therefore, in the medical room shown in Fig. 5, the patient passes through the curtain 54 hung at the patient entrance and enters the changing room 52, and then undresses according to instructions from the doctor or nurse, or from the voice synthesis IC. After that, the patient sits on the seat 17 of the examination table facing left with respect to the curtain 51. At this time, the curtain 51 prevents doctors and nurses from seeing the patient.

Then, although not shown, the pressure-sensitive switch provided on the backrest 15 is activated, or the rotating body 5 of the examination table is rotated by the operation of the doctor or nurse, and the rotation body 5 is rotated as shown by the dotted line in the figure. Since the sheet 17 directly faces the curtain 51, the patient also faces the curtain 51.

If the backrest 15 of the examination table is laid down and the seat 17 is evacuated in this state, as shown by the dashed line in the figure,
The lower part of the patient's abdomen has entered the examination room 53 through the curtain 51, and the patient is in the examination position due to the movement of the examination table.
Examinations and medical treatment will be performed by nurses.

At this time, the patient's face, the doctor, and the nurse are separated by a curtain 51, so the examination and treatment are performed without them seeing each other, and when the examination is finished, the above-mentioned reverse operation is performed. , the patient returns to a sitting position, and the examination table faces to the side, allowing him to get off the table.

FIG. 6 shows an embodiment in which the patient entrance is provided on the wall facing the curtain 51. In this case, it is desirable that the examination table can be rotated 180 degrees so that it faces directly and oppositely to the curtain 51. .

〔Effect of the invention〕

As mentioned above, the present invention allows the buttocks to rest on the seat,
After the patient is seated with the lower limbs supported on the crotch support, the backrest is laid down and the seat is retracted behind the seat, allowing the patient to be guided into the examination position.

Therefore, it is no longer necessary for the patient to perform the difficult movement of moving forward until the waist is lifted in a supine position with the lower limbs supported by the crotch support, and there is no need for the doctor or nurse to assist in this movement.

In this examination position, the waste case is positioned below the patient's buttocks, so the patient's private parts can be washed with water, gauze, etc., and the cover hangs down in front of the seat. do,
This prevents splashes of sewage from splashing onto the seat.

Therefore, when the patient sits in a sitting position, the discomfort of the buttocks resting on the dirty seat and the staining of the buttocks are prevented, and since the dirt case is covered with a cover and cannot be seen, the patient feels unclean. It's nothing like that.
