Abstract
A suction system for capturing aerosols in dental operatories, primarily comprising a means of suction, a collector and the intermediary connections. The means of suction is located in a compartment or area outside the operatory. The collector location is adjustable, but it is primarily placed at the patient's chin, adjacent to his or her mouth. Then, through the means of suction, the contaminated aerosols ejected from a patient's mouth during instrumentation will be removed from the operatory and released into a safer area.
Description
Suction System for Dental Aerosols Background of the invention (a) Field of the Invention This invention, a suction system for dental aerosols, is for collecting contaminated aerosols generated during dental procedures as a means of lessening the possibility of dental professionals of contracting infectious diseases.
(b) Description of Prior Art Accordingly, when dental professionals are treating their patients, they generally will wear masks as protection from their patients. However, in the process of dental treatment, powered instruments such as dental hand pieces and ultrasonic cleaners produce significant force which then causes the patient's saliva and blood to be ejected out from the patient's mouth in an aerosol form. This saliva-blood-water mix forms a mist that spreads all over in the air. If the patient is infected with high-risk infectious diseases that can be contracted through saliva, such as a Coronavirus infection, the operators cannot ascertain that they have actually blocked the infectious aerosol with only their masks.
Previously, the standard of care during dental treatment was a Level-3 mask and eye protection, which has been found to be insufficient protection with regards to aerosolised infectious material. This invention improves on existing methods of evacuating aerosolised material from the operating space in a manner that is reasonably nonintrusive, cost efficient, and effective.
Furthermore, the other patients and administrative staff do not wear masks and hence dental practices have become an effective vector for aerosolised infectious diseases.
Summary of the Invention In view of this, the inventor has devoted research effort and discovered that by placing a high-volume suction collector near the patient's chin, the aerosolised liquids produced during dental procedures will be inhaled by said collector and will be released from the equipment into a safer area. Consequently, the possibility of contracting infectious diseases during dental procedures will be lowered.
For these reasons, the main objective of this invention is to provide suction equipment for dental operatories that primarily comprises a means of suction, a collector, and the appropriate tubing and ducting to connect said means of suction and said collector together. This system removes infectious aerosols away from the operatory, where it can cause further disease, and releases it into an area where it can not cause such issues.
Another objective of this invention is to provide a suction system for dental operatories which has attachable and disposable collectors. The collectors can be replaceable and therefore will not infect other persons because of having contact with the patients.
Another objective of this invention is to allow a single system to service as many dental operatories as required. Allowing for a system of ducting to connect multiple collectors, for cost-efficiency, to multiple means of suction, for reliability and dependability, makes this invention superior to other methods that have been developed previously.
The following detailed explanations will make the other objectives of this invention and the detailed structure become clearer, at the same time, with reference to the enclosed drawings, one will have more understanding on the technology and contents of this invention.
Brief Description of the Drawings FIG. 1 is a drawing of this invention.
FIG. 2 is a drawing of a collector of this invention.
DETAILED DESCRIPTION OF THE INVENTION
As illustrated in FIG. 1, this invention of a suction system for dental operatories mainly comprises a collector 10, which is attached to an adjustable hose 13, which runs through arm 12, and is connected by ducting 14 to a means of high volume suction 16.
The collector 10 can be adjusted to various positions and angles using arm 12.
The high volume suction source 16 has an air inlet 18 and air exhaust 20.
This embodiment is designed such that the arm 12 is integrated directly with the dental chair unit 30. The arm 12 is rigid with joints that can pivot and articulate, allowing the collector 10 to be moved into a desired position. The collector 10 is generally funnel-shaped, with the larger open end facing towards the patient 32. Inside the hollow arm 12 is a flexible suction hose 13 that extends from the fixed ducting 14 to the collector 10. Said flexible suction hose 13 has a smooth bore to minimize material buildup and is chemical resistant. It has a slightly corrugated outer helix to promote abrasion resistance and resist collapsing under suction. The fixed ducting 14 in this embodiment is composed of large-bore ABS pipe which is also smooth inside to allow air to flow easily and to facilitate cleaning. Metal ducting will typically be used for systems that serve more than one operatory.
As shown in FIG. 2, this invention also can integrate a light 22 into the collector 10 to aid with visualisation.
As shown in FIG. 1, when this invention is used in practice, arm 12 will bend such that the collector 10 is positioned directly in front of the chin of the patient 32. When a dentist or dental hygienist uses equipment that creates an aerosol, such as a high speed hand piece or ultrasonic cleaner, said aerosol will be pulled into the means of suction 16 via collector 10. For illumination purposes, a spotlight comprising a bulb 22 and a reflector 24 may be mounted on the collector 10. This collector 10 may be one that is disposable.
While the present invention has been described in connection with specific embodiments thereof and in a specific use, various modifications will occur to those skilled in the art.
The scope of the claims should not be limited by the embodiment or the examples given but should be given the broadest interpretation consistent with the description as a whole.
