Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applied to obstetrics and gynecology and urology, in which patients are placed on a crotch support and their legs are opened in order to examine the affected area of the patient. Regarding improvements to medical examination tables.

[Conventional technology]

A conventional examination table for obstetrics and gynecology of this kind has a backrest that can be raised and lowered relative to a seat on an elevating table, and a crotch support that spreads and supports the patient's crotch. A filth case is attached below the container to hold gauze and other filth.

Then, the patient is seated on the seat, the patient's crotches are spread apart, and the patient is supported by a crotch support, and then the patient's backrest is tilted back to a supine position, and the affected area is examined.

[Problem that the invention seeks to solve]

In conventional obstetrics and gynecology examination tables, if the patient is seated on the seat and the backrest is simply tilted down, the seat is positioned under the patient's private parts and gets in the way. There is a risk of staining the sheet.

Therefore, after the patient is placed in a supine position, the patient must move forward until the buttocks are at the edge of the seat, with both thighs supported by the crotch supports.

Since the above-mentioned movements are extremely difficult for patients to perform, doctors and nurses have had to take the time to help patients with these movements.

On the other hand, patients are also embarrassed to take off their clothes in front of doctors and nurses, and patients who are elderly, patients who have been brought to the hospital with symptoms such as dislocated hips or lower abdominal pain, or patients who are in the final stages of pregnancy The movements required to assume these examination postures are particularly difficult.

The nurse then tries to guide the patient to the appropriate location for the examination, but at this point the patient becomes extremely nervous and may not be able to perform the examination smoothly or may even refuse the examination.

Furthermore, when patients get on and off the examination table, they may get their feet caught on equipment such as crotch supports, damaging the equipment, and patients are unable to wipe the affected area by themselves because the examination is completed in a supine position. There are disadvantages such as the need for nurses to wipe and the patient's discomfort due to embarrassment.

As a result, medical treatment is not carried out smoothly, takes time, and has the disadvantages of placing a heavy mental and physical burden on the patient.

[Means for solving problems]

The present invention is intended to solve the above-mentioned problems of the conventional art.It eliminates the embarrassment and difficult movements of patients, saves the labor of doctors and nurses, and enables smooth medical treatment. includes a backrest that can be raised and lowered integrally with a seat in which a recess is formed, a raising and lowering operation unit that raises and lowers the backrest and the seat, and a recess that is movable between the recess of the seat and the rear of the seat. An obstetrics and gynecology examination table comprising: a seat; an in/out operation section for displacing the seat; and a base for rotatably supporting the backrest, seat, and seat in a horizontal direction. It will be done.

[Effect]

The obstetrics and gynecology examination table of the present invention allows the patient to sit with their buttocks on the seat and lean against the backrest, and then the patient is suspended in a desired direction, for example, into the treatment room, by rotating the base. , directly facing the curtain that separates the patient's abdomen and above from the doctor.

Next, after tilting the backrest backwards and having the patient assume a supine position, the seat under the patient's buttocks is retracted backwards from the recess in the seat, and the patient's legs are supported by the crotch supports. The patient is asked to take an examination position that exposes their private parts.

〔Example〕

An example of implementing the invention will be described below with reference to FIGS. 1-4.

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 1 is attached to the ram of the lifting cylinder 11.
A roller 10 that rolls along the roller 10 and guides the elevation.
An elevating outer cylinder 9 having a diameter is attached.

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. 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 2.
Consists of 1.

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, it is possible to prevent splashes from the dirt case 27 from being applied to the seat 17.

The height of the patient 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 waste case 27 is not removed from the fixed table 24, the fixed table 24 always maintains a horizontal position, so sewage will not spill from the waste case 27, and the patient will be able to move forward as the seat 17 moves forward. The sewage tray 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 partitioned 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 the curtain 51 and to the left side 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 described above, in the present invention, the patient places his buttocks on the seat, sits down with his lower legs supported by the crotch support, and takes a posture leaning against the backrest.

Then, by rotating the base, the backrest, the seat, and the seat are horizontally rotated, and the patient is placed in a desired direction in the treatment room, for example, directly facing a curtain hung in the treatment room.

Next, when the backrest and seat are tilted backwards, the patient is in a supine position, and the patient's abdomen and below are on the other side of the curtain, so the doctor and nurse cannot see the patient's face. .

Further, when the seat is retracted rearward from the recessed portion of the seat, the patient's buttocks are in a floating state and the patient's lower legs are supported by the crotch support, so the patient automatically assumes the examination posture.

Therefore, it is no longer necessary for the patient to perform difficult movements in which the patient has to move forward until the buttocks are in the air with the lower limbs supported by the crotch support, and there is no need for the doctor or nurse to assist with this. becomes.

Also, after the examination is complete, return the seat to the recess in the seat to support the patient's buttocks, raise the backrest to place the patient in a sitting position, and rotate the backrest horizontally.
The patient must be able to stand up easily without being obstructed by equipment, curtains, etc. in the treatment room.
