Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a spittoon device that is used in a dental clinic and is composed of a bowl having a water inlet and a water outlet for patients to gargle.

[Conventional technology]

Conventional spittoon devices of this type are attached to the side of the patient chair, on the floor near the chair, or attached to the patient chair so that the patient can gargle while sitting on the chair. , this could not be moved.

[Problem that the invention attempts to solve]

However, depending on the position of the patient's tooth to be treated,
It may be easier to perform the treatment if the doctor or assistant is on the side of the patient, but in this case the spittoon in the aforementioned position may get in the way.

Furthermore, since the position of the spittoon is within the flow line of the assistant, there is also the drawback that it is difficult for the assistant to move.

Furthermore, since piping for water supply and drainage to the spittoon was required just for that purpose, there were also drawbacks such as increased construction costs.

[Means for solving problems]

This invention is intended to eliminate the above-mentioned drawbacks of the conventional spittoon device. By installing the spittoon in the partition unit, there is no need for wiring for that purpose, reducing construction costs, and making it possible for the treatment and assistant During the operation, the spittoon is moved closer to the partition unit so that it does not interfere with the treatment or operation, but when the patient wants to gargle, the patient can do so easily while still seated. The means includes a partition unit that partitions a treatment room into treatment sections, a U-shaped rail formed to protrude from one side of the partition unit, a guide roll attached to the side of the U-shaped rail, and the rail. It has a roll that can move inside the
A rail with a recess formed at the tip side that moves within the U-shaped rail, a cover frame that moves integrally with the rail, a spittoon attached to the front end of the cover frame, and a spittoon connected to the spittoon. It is equipped with a water supply and drainage pipe that runs through the covered frame.

[Effect]

The dental spittoon device of the present invention is installed in a partition unit that divides a treatment room into multiple treatment sections, so it can be installed in each treatment section, and by piping to this partition unit, it can be connected to the spittoon. Piping is also done, and if the spittoon is brought close to the partition unit, it will be released to the side of the patient chair, so it will not interfere with the treatment or circulation, and if it is extended from the partition unit, it will be released to the side of the patient chair. The guide roll can be positioned close to the side, and when the rail is housed in the U-shaped rail, the guide roll enters the recess of the rail, so that the rail does not unnecessarily protrude forward.

〔Example〕

An embodiment in which a plurality of treatment sections are formed in a treatment room using a partition unit employing the present invention will be described below with reference to the drawings.

In Figures 1 to 3, A ₁ is a partition wall that separates the patient passage side, and on one side of it is a medical treatment section B.
A partition wall _A2 is connected to one side of a partition unit C that partitions the space.

A patient chair D is installed in each of the plurality of treatment sections B thus formed, and patients are seated in a partition wall.
A patient enters treatment area B from between A ₁ and bulkhead A ₂ of adjacent treatment area B, is seated on chair B ₁ , and is set up so that the doctor and assistant enter through the edge of partition unit C. It is.

The partition unit C is equipped with equipment necessary for medical treatment, such as a doctor table D, an assistant table E, a film viewer F, a spittoon G, a dust suction arm H, and a brushing mirror.

This brushing mirror is used to instruct patients on how to brush their teeth by showing them how they are brushing their teeth.

Next, the doctor table D mentioned above is
FIG. 7 will be explained.

There is a bulkhead below table C ₁ in Figures 1 and 2.
A guide rail 1 bent in an L-shape or a U-shape is attached to the end opposite to _A2 .

Two rollers 2 are installed on the top surface of this guide rail 1.
A movable body 5 that can move along the guide rail 1 is movably supported with two rollers 3 on the front side and one roller 4 on the back side.

A rotating body 6 is attached to the lower surface of the moving body 5 so as to be rotatable in the horizontal direction, and two rollers 7 of the rotating body 6 are in contact with the front surface of the rail 1.

Therefore, when all of the rollers 7 of the rotating body 6 are in contact with the rail 1, the rotating body 6 cannot rotate relative to the moving body 5, but as shown in FIG. When the rail 1 moves to an L-shaped position at the end of the rail 1, one roller 7 of the rotating body 6 becomes free, and the rotating body 6 becomes rotatable.

A support 8 is fixed to this rotary body 6, and a support rod 10 and a support frame 11 are connected between it and the base 9 of the doctor table D.
are supported in such a way that their fulcrums form parallelograms.

Therefore, the support rod 10 and the support frame 11 rotate while maintaining a parallel state around the fulcrum of the support 8, and therefore, the doctor table D attached to the top surface of the table 9 can rotate up and down while remaining horizontal. You can move to

A guide roller 12 is pivotally attached to the support frame 11, and an arm 14 is pivotally attached to one end of a chain 13 at the fulcrum between the stand 9 and the support rod 10. It is slidably fitted on the shaft of No. 12.

Therefore, the rotation angle of the support rod 10 and the four support frames 11 with respect to the support body 8 is such that the elongated hole 14a is
The range in which the axis can be moved is limited,
The vertical height of the doctor table D attached to the stand 9 is limited to a certain range.

The chain 13 is fixed to a fixing piece 16 to which one end of a spring 15 is fixed via the upper surface of the guide roller 12, and the other end of the spring 15 is attached to a fulcrum of the support frame 11 and the support body 8. It is fastened to a fastening piece 17 that is screwed into the screw rod 18.

Therefore, when the table 9 also descends as the doctor table D descends, the spring 15 is stretched by the chain 13, and the gravitational force applied to the table 9 due to the drag force causes the doctor table D to move downward. Balance, Doctor Table D
can be stopped at any height.

Then, by rotating the screw rod 18, the fastening piece 17 is moved and the strength of the spring 15 is adjusted to achieve the optimum balance.

In this way, the doctor table D can be moved back and forth, so when the doctor enters and leaves the treatment area B, he moves it to the end of the rail 1 and moves it to the end of the rail 1, as shown by D'' in FIG. It also rotates to the retracted state so that it does not get in the way of entering and exiting the room.

In addition, when a patient enters treatment area B, sits on chair B ₁ , and is interviewed and examined in a standing position,
Doctor table D can be used by moving doctor table D to position D'.

Furthermore, when examining or treating a patient in a supine position, the device is returned to the D position near the patient's head.

A support 19 of a holder 20 for hooking and supporting a tool used for machining teeth of an air turbine or the like is attached to the lower surface of the doctor table D as shown in FIG. Far ultraviolet tube 50
is installed.

Therefore, tools such as an air turbine can be held in the holder 20.
If you hook it to a
Bacteria on these tools are killed and good hygiene is maintained.

Further, on the front surface of this holder 20, a cover 21 is provided in two stages, the front surface of which can be opened by rotating in the direction of arrow a. It is designed so that it can be rotated sideways to the closed state shown in FIG.

Therefore, by closing this when not in use, it is possible to increase the efficiency of far ultraviolet irradiation, and also prevent dust and bacteria floating in the air from adhering to the tool. This can prevent doctors from becoming infected with bacteria.

Next, the 9th film viewer F, which holds an X-ray photograph, etc., and looks through it with a light beam from the rear, is installed.
10 will be explained.

This film viewer F is composed of a frame body 23 with a frosted glass 22 on the front side and a fluorescent lamp housed _inside . It is attached to the other end of a support rod 24 which is supported and is rotatable in the horizontal direction.

Therefore, the support rod 24 can be rotated and pulled out from the partition unit C to any desired position, and the support rod 24 can be pulled out to any desired position.
It can be oriented at any angle relative to 4.

Therefore, it is possible to make good use of the X-ray photographs, such as by explaining medical treatment while showing the X-ray photograph to the patient, or by bringing the X-ray photograph close to the patient's head and performing treatment while looking at it.

Next, the patient should gargle with Spitton G first.
11 to 13 will be explained.

In the partition unit C, a window hole _3C3 is bored in the wall opposite to the side where the doctor table D is installed, and a support arm 26 with a rail 25 whose upper and lower sides are guide surfaces is fixed in the center of the window hole 3C3. Moreover, a guide roll 27 is rotatably attached to the tip of this support arm 26.

Spitton G is the drain fitting 29 at the tip of the covering frame 28.
A drain pipe 30 from the drain fitting 29 passes through the support arm 26 and is connected to a drain pipe under the floor.

Then, an inner frame 31 fixed inside the cover frame 28
A roll 32 that rolls between the upper and lower guide surfaces of the rail 25 is attached to the rail 25, and a rail 33 having a recessed portion 33a near the outer end is attached. It is placed there.

Therefore, the rail 33 is guided by the guide roll 27, and the roll 32 rolls on the rail 25, so that the covering frame 28 can be pulled forward or pushed backward with respect to the support arm 26. .

As a result, the spittoon G is connected to the partition unit C.
The patient can easily gargle by pulling it forward and bringing it close to the patient.

However, when not in use, the spittoon G is moved closer to the partition unit C to widen the distance between it and the patient, making it easier for the assistant to work. This prevents Spitton G from sticking out easily.

Further, regardless of the position of the spittoon G, the drain pipe 30 passes through the cover frame 28 and the support arm 26 and is not visible from the outside, so that the appearance is not spoiled.

Next, during patient treatment, bacteria, tooth polishing powder, etc. that are scattered from the patient's oral cavity are absorbed, and the doctors and assistants inhale the airborne particles.
The dust suction arm H for preventing infection with diseases will be explained with reference to FIGS. 14 to 18.

This dust suction arm H is provided below the table C ₁ of the partition unit C, and has a rotary shaft 34 rotatably attached to the partition unit C, and is attached to the tip of a first arm 35 that is rotatable in the horizontal direction. A rotating shaft 36 is rotatably attached.

The base ends of a first support rod 37 and a second support rod 38 are pivotally supported on the rotating shaft 36, and a support body 39 is pivotally supported at the tips of these, and these pivot points are parallel to each other. It forms a quadrilateral.

The first arm 35 rotates in the horizontal direction by the rotation of the rotation shaft 34 to pull out the rotation shaft 36, and further rotates the first support rod 37 and the second support rod 38 in the horizontal direction by the rotation of the rotation shaft 36. It is possible to rotate the support body 39 and pull it out to any position in the horizontal direction.

A bolt 40 is screwed into the middle of the second support rod 38, and by its rotation, the lengths of the rotating shaft 36 and the support body 39 are adjusted, and the lengths of the first support rod 37 and the second support rod 38 are adjusted. Together, the supports 39 are kept vertical.

Further, a spring 41 is stretched between the first support rod 37 and the second support rod 38, and the weight and other loads applied to the support body 39 due to the biasing of the spring 41 cause the first support rod 37, The second support rod 38 prevents the support body 39 from rotating in the direction of lowering it.

A limiting arm 42 having a long hole 42a is pivotally attached to the pivot point between the second support rod 38 and the rotation shaft 36, and the long hole 42a is connected to the pin 37a of the first support rod 37.
It is slidably mated to the

By this fitting, the first support rod 37 and the second support rod 3
8 rotates in the vertical direction, the pin 37a is inserted into the elongated hole 4.
2a, but the pin 37a is inserted into the elongated hole 42.
By reaching the end a, the rotation angle of the first support rod 37 and the second support rod 38, that is, the vertical position of the support body 39 is limited within a certain range.

Further, a plate 37b is fixed to the left and right side surfaces of the first support rod 37, and a plurality of through holes 38a are bored between the plates 37b in the second support rod 38, and the inner surface of the second support rod 38 is formed in the through holes 38a. Two pistons 43 each serving as a pressure surface are inserted symmetrically, and a compressed air pipe 44 is connected between the pressure surfaces of each piston 43.

Therefore, when compressed air is introduced between the pressure surfaces of the piston 43, the outer end of the piston 43 is brought into contact with the plate 37.
b, and in order to stop the movement of the plate 37b, the vertical rotation of the first support rod 37 and the second support rod 38 is stopped.

The support body 39 can thus be stopped at a position near the patient's face.

An L-shaped plate 45 is attached to the lower surface of the support body 39 so as to be freely rotatable in the horizontal direction, and a suction port 46 is attached to this L-shaped plate 45 so as to be freely rotatable in the vertical direction. It can be oriented in any direction, up, down, left, or right.

A pipe 4 connected to this suction port 46
7 is a cover plate 48 of the first support rod 37 and the second support rod 38;
and is connected to the vacuum device through the inside of the first arm 35.

Therefore, if this suction port 46 is placed close to the patient's oral cavity and directed in that direction, the dust scattered during treatment and the bacteria emitted from the oral cavity will be inhaled together with the air, and the doctor or assistant will inhale this and become infected. It is possible to prevent this and also to prevent indoor contamination.

Finally, the assistant table E is a table on which a vacuum mouth for inhaling saliva and treatment dust in the patient's oral cavity, a water injection nozzle for injecting cleansing water into the oral cavity, and the like are hung.

[Effect of idea]

As described above, in the present invention, if the clinic room is partitioned into multiple treatment sections using this partition unit, a spittoon can be installed in each treatment section, and the piping can be connected to the partition unit. Piping is simplified and construction costs can be reduced.

In addition, by keeping the spittoon close to the partition unit using the guide rail, the sides of the patient chair are wide open, which does not interfere with the treatment or the flow of the assistant, making it easier for the assistant to operate.

Furthermore, by extending the spittoon from the partition unit, it can be brought close to the side of the patient's chair, allowing the patient to gargle while sitting in the same manner as in the past.

Since the piping from the partition unit to the spittoon is covered by a cover frame, the unsightliness of exposing these pipes is further exacerbated by the fact that when the cover frame is pushed into the partition unit side, the guide roll is pushed into the recess of the rail. Because it fits in, the Spitzton unit does not accidentally stick out from the stored state.
Therefore, it has the effect of not interfering with the treatment of the doctor or assistant.
