JP2001340362A - Contamination cleaning device for clinic room - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve the problem raised by the conventional contamination cleaning device which is used for cleaning the contamination of a dental clinic room caused by nitrous oxide, dust, etc., that the operability of an arm is worsened due to the heavy weight of the whole body of a duct member resulting from many bellows-like flexible pipes used in the duct member and, in addition, the sucking capacities of the bellows-like flexible pipes are lowered by large air resistances generated in the flexible pipes when air passes through the pipes. SOLUTION: This contamination cleaning device is constituted in such a way that first elbow pipes A and B (7 and 8) are connected to a base-part pipe (6) provided on a main body stand (1) and a second intermediate pipe (30) is connected to the elbow pipes A and B (7 and 8) through a first intermediate pipe (29) and second elbow pipes A and B (9 and 10). In addition, fourth elbow pipes A and B (13 and 14) and fifth elbow pipes A and B (15 and 16) are connected to the intermediate pipe (30) through third elbow pipes A and B (11 and 12) and a suction hood (5) is fixed to the fifth elbow pipe B (16). Moreover, two sets of link mechanisms (31 and 32) are provided.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction device for purifying contamination in a doctor's office.

[0002]

2. Description of the Related Art In a dental clinic, when a patient's teeth or dentures begin to be ground, blood, saliva,
Blood, saliva, and dust, which are filled with dust and fly out of the mouth, diffuse while scattering from the grinding point. Since the air turbine has a high speed of 300,000 to 500,000 revolutions per minute, the flying dust and the like is cut into micron-sized particles, inhaled by dental clinic staff, and stays at the end of the alveoli, causing pneumoconiosis. Becomes 90% of grinding contamination dust by air turbine
Is the most harmful to the human body with a size of 0.6 to 5μ, and bacteria attach to all nuclei such as dust, and together with viruses contained in blood and saliva, put dentists and other staff at risk. There's a problem. Those with a size of 10 μm or more are caught and pushed out by the cilia of the organ, and are discharged out of the body together with sputum.

Conventionally, an assistant inserts a suction nozzle made of a thin pipe into a patient's mouth together with a cutting machine to perform vacuum suction. However, the effect of removing dust and the like by this method is unexpectedly small, and is about 5 μm or more. Dust and the like can only be sucked, and dust and the like having a size of less than 5 μm are scattered in the clinic. Dusts such as 0.6μ-5μ which are the most dangerous for dental clinic staff such as dentists are scattered, and infectious disease viruses and bacteria are attached to them. Among them, AIDS virus, hepatitis C virus, type B The incidence of respiratory system, circulatory system, hepatitis B, etc. is extremely high because the dental clinic staff inhales a large amount of air with air contaminated by hepatitis virus or the like every breath.

[0004]

As described above, contamination of the dental clinic by anesthetic gas such as laughter and dust and the like has become a problem. However, in the conventional product, a bellows-shaped flexible pipe is provided at the bent portion. Due to heavy use, the entire duct member becomes heavy, and thus the operability of the arm is poor. In addition, when air passes through the bellows-like flexible pipe, a large air resistance is generated inside the pipe and the suction capacity is reduced. This is a major factor. In order to compensate for this drawback, the conventionally installed dust collector becomes large, and as a result, the air resistance further increases and the suction noise increases.

The present invention has been made to solve these problems, and an anesthetic gas such as laughter, which is a cause of contamination of a clinic such as a dentist, and dust generated by grinding of a patient's teeth. The use of an elbow pipe reduces the unpleasant suction noise of conventional bellows-like flexible pipes, and further improves the suction capacity. To prevent water drops from the suction hood opening when the vacuum is stopped, as seen in conventional products,
It is another object of the present invention to solve a major drawback of the bellows-shaped flexible pipe that cleaning and sterilization cannot be performed.

Further, by solving the above-mentioned disadvantages,
In other words, by using an elbow pipe without using a bellows-shaped flexible pipe, cleaning and sterilization of the duct member becomes easy, and not only the use of dental staff but also general medical care such as dermatology and orthopedic surgery. Staff can be used.

[0007]

According to the present invention, a suction hood is connected to a main body stand via a duct member. The duct member includes two intermediate pipes and first to fifth elbow pipes A and B. In addition, the suction hood-side part can be rotated around the axis of the base pipe, and can be bent at an appropriate angle by a link mechanism. The aforementioned elbow pipe rotates the suction hood-side part. The suction hood can be bent around the mouth of the patient by the fifth elbow pipes A and B, so that the suction can be performed by holding the handle provided on the fourth elbow pipe A or the like. The hood can be freely and easily located at a position where it can most effectively absorb and remove anesthetic gas, dust, and the like as long as it does not interfere with the patient's treatment. Then, the anesthetic gas, dust and the like sucked from the suction hood into the stand together with the air are guided to a dust collector installed outside the medical office and processed.

[0015]

As described above, according to the present invention, the anesthesia gas and the dust and the like generated by grinding teeth and dentures immediately after being scattered into the clinic around the outside of the patient's mouth are aspirated. Since these can be removed and discharged outside the clinic, it is possible to purify the contamination due to the anesthetic gas and also to sufficiently remove dust and the like, and therefore, it is possible to eliminate the adverse effects of the anesthetic gas and dust etc. on the clinic staff such as dentistry. ,
Since anesthesia gas, dust and the like are sucked from the suction hood communicating with the main body stand, only one dust collector is required, the structure is simple, and the effect that the device is small can be obtained.

Further, by exhausting anesthetic gas and dust to the outside of the hospital, anaerobic bacteria are killed by being discharged into the atmosphere, and Gram-negative bacilli have an infectivity of bacteria when exhausted. There is almost no chance of falling infection. Fungi are killed by ultraviolet light upon discharge to the atmosphere, whereas gram-positive cocci are diluted by the air and have a reduced infectivity and little chance of infection.

Further, since there is no projection inside the duct as seen in a conventional bellows-shaped flexible pipe, the suction ability can be improved and the suction noise can be reduced. Furthermore, since the duct member is easily removable,
Washing and sterilization can be performed by removing from the main unit stand.
