DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a dental clinic,
The present invention relates to a spitton ball for dental care used when a patient performs gargle after treatment and after brushing.

[0002]

2. Description of the Related Art Conventionally, a spitton ball is generally fixed to a side surface of a treatment chair or independently fixed to a floor surface, and is used by a patient after treatment or brushing. Later, she was able to gargle while sitting in the treatment chair.

[0003]

By the way, the above-mentioned conventional spitton ball becomes an obstacle when a dentist performs a treatment or when a patient sits on a treatment chair, and is always in a place where the patient can see. Therefore, there is a problem that the patient has a fear of the treatment, the beauty is deteriorated, and the patient is unsanitary.

The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to draw out a doctor unit used by a dentist from the back surface of a doctor unit to a patient side only when the patient is gargling. Therefore, it is an object of the present invention to provide a dental care spitton ball that does not always enter the eyes of a patient, does not cause fear to the patient, and does not impair the aesthetic appearance.

[0005]

The spittoon ball for dental care of the present invention achieves the above-mentioned object.
The means include a slide rail attached to the back surface of the top plate of the doctor unit, a ball attached to the back surface of the doctor plate by the slide rail, and a motor attached to the back surface of the top plate. And a moving nut screwed to the screw rod and attached to the ball side.

A limit switch attached to the back surface of the top plate for shutting off the power of the motor when the ball reaches the maximum projecting position, and shutting off the power of the motor when the ball reaches the maximum accommodating position. And a limit switch.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a spitton ball for dental treatment according to the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing the entire dental care apparatus, A is a doctor unit used by a dentist accommodating the spitton ball of the present invention, and includes a treatment instrument used by the dentist during treatment. A hanging therapeutic instrument and storage space are provided. B is a treatment chair in which a backrest is raised and lowered, and a seat portion can be rotated up and down and rotated by a predetermined angle manually, C is an assistant unit provided with a device used by an assistant, and D is the treatment unit. The dental light D is attached to the upper ceiling of the chair B and illuminates the mouth of the patient when the chair B is turned down.

Next, the details of the doctor unit A will be described with reference to FIGS. Reference numeral 1 denotes a top plate, which is formed to have a height higher than that of a general office desk, for example, by forming a storage shelf for storing a treatment instrument on a lower surface. For this reason, if the user places an arm on a corner in order to perform a business such as creating a medical chart or to strike a computer keyboard or the like, a part of the arm is squeezed and becomes painful, as shown in FIG. As described above, the corner 11 is formed in a tapered shape so that the portion in contact with the arm is enlarged to increase the compression area and reduce the feeling of compression.

The plane shape of the top plate 1 is a straight portion 12
And a linear portion 13 formed on a part of the other side opposite to the linear portion 12, and a projecting portion 14 projecting from the linear portion 13 in a mountain shape, and a caster is attached to the linear portion 13. A doctor's chair is arranged, and a treatment chair B is arranged outside the projecting portion 14.

Reference numeral 2 denotes a panoramic viewer mounted on the side of the linear portion 12 of the top plate 1 and viewed from the back with an X-ray photograph interposed therebetween. A storage shelf 4 for accommodating external devices such as an internal camera is a monitor television.

Reference numeral 5 denotes a doctor table in which a medicine or the like can be stored on the upper surface of the upper plate 51, and a holder 52 for hanging a treatment instrument such as a handpiece is attached to the front side of the upper plate 51. One end of the upper plate 52 is fixed to the upper end of the frame 53, and the lower end of the frame 53 is rotatably supported by one end of the swing arm 54. The other end of the swing arm 54 is rotatably supported by a flange bracket 55 fixed to a floor or a leg plate for placing the doctor unit A on the floor. Reference numeral 56 denotes a handle attached to the upper surface plate 51.

The doctor table 5 constructed as described above
When the treatment is started, the user pulls the handle 56 toward the user and pulls the upper plate 51 upward by the frame 53, the swing arm 54 and the flange bracket 55.
When the treatment is completed, the patient is pushed down while holding the handle 56 to be housed in the lower part of the top plate 1 (dashed line in FIG. 4).

Reference numeral 6 denotes a spitton ball according to the present invention, which is attached to the back surface of the top plate 1 so as to be housed and pulled out. The details of the spitton ball 6 will be described below with reference to FIGS. The ball 61 is mounted on a frame 63 bridged between a pair of first slide rails 62, and the first slide rail 62 is mounted on a second slide rail 65 fixed via a mounting plate 64 on the back surface of the celestial body 1. It is slidably supported with respect to this. A hose fitting 61b for attaching a drain hose (not shown) is formed on the drain metal fitting 61a at the bottom of the ball 61.

A moving nut 66 is attached to an end (lower side in FIG. 6) of the frame 63, and a screw rod 67 is screwed to the moving nut 66. One end of the screw rod 67 is attached to the mounting plate 64. The other end is connected to the output shaft of a motor 68 fixed to the mounting plate 64 via a coupling 67b. 69
Reference numerals a and 69b denote limit switches for detecting the maximum projecting position and the maximum accommodating position of the ball 61.

In the spitton ball constructed as described above, when a dentist operates a switch (not shown) when the patient performs a gargle, the motor 68 rotates to rotate the screw rod 67. The ball 61 is guided by the first and second slide rails 62 and 65 and protrudes from the top plate 1 (to the left in FIGS. 5 and 6). When the limit switch 69a detects the maximum projecting position, the motor 68
The power supply to is stopped, and the protrusion of the ball 61 is stopped.

When the motor 68 is rotated in the direction opposite to the above when the patient finishes cleaning, the ball 61 is housed on the back surface of the top plate 1 by the operation opposite to the above, and the limit switch 69b Detects the maximum accommodating position, the power supply to the motor 68 is cut off and the ball 61 stops. Reference numeral 61d denotes a cup holder for placing the cup, and this part protrudes from the top plate 1 even when the ball 61 is in the housed state.

[0017]

As described above, according to the present invention, the spitton ball is attached to the back of the top plate of the doctor unit so that it can be freely taken in and out, and after the patient is treated or brushed, the dentist operates the motor to rotate the ball. Is pulled out near the patient and is stored on the back of the table during counseling and treatment, so it does not disturb the treatment or introduction of the patient, and feels fear or unsanitation to the patient I will not let you.

Further, since the limit switch is mounted at the maximum protruding position and the maximum accommodating position, when the ball reaches the maximum protruding position or the maximum accommodating position, the limit switch cuts off the power supply to the motor, and automatically moves to a predetermined position. This has the effect that the ball can be stopped immediately.
