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.

In this examination table, the patient is seated on the seat 32, the crotches are spread and raised, and the crotch supports are used to support the patient, and then the backrest 33 is tilted back and the patient is placed on his back.
The patient's affected area is examined and the filth and sewage generated at that time are stored in the filth case 35.

[Problem that the invention attempts to solve]

The conventional examination table is constructed as described above, but if the patient is seated on the seat 32 and the backrest 33 is only laid down, the seat 3 will not be placed under the patient's buttocks.
2, the sheet 32 is not only covered with debris that makes it difficult to perform a medical examination, but also becomes soiled with filth and sewage.

Therefore, after the backrest 33 is tilted 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. Have difficulty.

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 elderly patients and patients in the final stages of pregnancy.

In addition, the filth case has drawbacks such as dripping of sewage from washing the patient's affected area, and the resulting droplets staining the lower part of the examination table and causing rust and other malfunctions. Ta.

[Means for solving problems]

This invention solves the above-mentioned problems with conventional obstetrics and gynecology examination tables, and by retracting the seat in front of the reclined backrest, the patient's buttocks are raised, and the dirt case is removed. This is to prevent scattered dirt and sewage from adhering to the lower part of the examination table by exposing and raising the dirt cover.It has an auxiliary seat at the bottom that supports the lower back, and a crotch support in front of the auxiliary seat. a backrest portion which is rotatably supported on a bracket; a undulation means for raising and lowering the backrest portion; a seat supporting the buttocks; and an extrusion cylinder having one end pivotally supported on the backrest portion. , an arc-shaped slide bar having one end pivotally supported by the ram of the extrusion cylinder and the other end attached to the lower end of the seat; a plurality of guides provided at the lower part of the backrest portion to guide the slide bar; a displacement means that includes a roller and moves the seat forward of the auxiliary seat and rearward of the auxiliary seat; and a pivot support that is rotatably biased by a biasing member to the backrest portion at the bottom of the auxiliary seat. When the sheet is positioned in front of the auxiliary sheet by the displacement means, it is rotated by the pressure of the slide bar against the urging force of the urging member, covers the upper surface of the waste case, and When the seat is positioned behind the auxiliary seat by the displacement means, the filth cover covers the front surface of the seat by the biasing of the biasing member, and when the backrest is in an upright position, the auxiliary seat is closed. The dirt case is attached at a position below the seat and at a position below and in front of the auxiliary seat when the backrest is in a prone state.

Next, by moving the slide bar backward, the seat supporting the patient's buttocks is retracted to the rear to lift the patient's buttocks into the examination position, and expose the filth case below the buttocks. filth,
Allow this to receive sewage.

At the same time, the filth cover is released from lying down by the slide bar, and the filth cover is erected by force.
This prevents splashes of sewage and filth from adhering to the seat or the lower part of the examination table.

〔Example〕

An example of implementation of the obstetrics and gynecology examination table of the present invention will be described 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 meshes with 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).

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, 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,
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 a contracted state, the fulcrum E is pulled and the slide bar L attempts to move rearward while being guided by the guide roller 21.

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 is composed of at least the extrusion cylinder 14, the slide bar L, and the guide roller 21.

A dirt cover 23 that 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 dirt cover 23 is biased by a spring 22. is sheet 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 dirt cover 23 is lost, 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 dirt cover 23 is tilted forward, and the fixing base 24 is located below the auxiliary seat 16 while maintaining the 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 15 backward, the patient assumes a supine posture, and then the push-out cylinder 14 is operated to pull the slide bar L backward.

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.
At this time, the fixed table 24 is positioned below the front of the auxiliary seat 16 and maintains a horizontal position, so if the waste case 27 is attached to it, the dirty water used in the medical treatment etc. can be poured into it. Can receive.

Furthermore, since the dirt cover 23 stands up on the front surface of the seat 17, it is possible to prevent splashes from the dirt case 27 from splashing onto 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 the waste water will not spill from the waste case 27, and the patient will be able to move forward as the seat 17 moves forward. The dirt case 27 does not interfere with getting off or getting on the seat 17.

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

This medical treatment room is partitioned by a curtain 51 into a patient's withdrawal room 52 and a doctor's treatment 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 idea]

As described above, the present invention retracts the seat backwards from under the buttocks of a patient who is lying on the backrest, lifts the patient's buttocks, and allows the patient to assume an examination posture. The filth case can be exposed.

Therefore, the patient no longer has to perform the inconvenient and difficult movement of moving forward while supporting the lower limbs on the crotch support, and the time and effort of the nurse who assists in this movement is saved, and the patient also enjoys relaxation. You can undergo a medical examination in this state.

At the same time, the dirt case exposed below the buttocks can receive dirt such as gauze used for cleaning the affected area, etc., and sewage.

At this time, the filth cover is erected by the movement of the slide bar that had been laying down the filth cover, preventing droplets of dripping sewage from scattering and adhering to the seat or the lower part of the examination table. Therefore, staining, rust, etc., are prevented.

When the slide bar is moved forward after the examination, the filth cover is laid down and the seat moves forward to support the patient's buttocks, allowing the patient to easily stand up from the seated position. be able to.

At the same time, since the filth case is prevented from being exposed by the sheet, the discomfort of the filth in the filth case coming into contact with the patient's eyes is eliminated.
