ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Field of the Invention
This invention, a vacuum equipment for medical tables, in particular, vacuum equipment used in medical tables' environmental hygiene so as to lessen the possibility of doctors and nursing staffs from contracting infectious diseases.
(b) Description of the Prior Art
Accordingly, when doctors are treating their patients, for health concern, the doctors generally will wear masks as protection from their patients; also, particularly in the process of dental treatment, grinding teeth is the commonest treatment for teeth, however, when the teeth of a patient were ground, the rotation of grinding machine will produce centrifugal force which then causes the saliva and blood to be spit out from the patient's mouth, the saliva and blood will mix with the air and form a mist that spreads all over in the air. Also, for ear, nose and throat treatment and out-patient service, endoscope and diagnosis of tubercular patients, if the patient is infected with high risk infectious diseases that can be contracted through saliva, the doctors cannot ascertain that they have actually blocked the infectious bacteria with only the masks. In addition, the doctors always find themselves being spitted all over by the patients after the treatment, it is absolutely not healthy and they will become one of the groups that are in the great risk of being infected.
Furthermore, the other patients and the nursing staff may not wear masks and hence the hospitals have become a good place to transfer infectious diseases.
SUMMARY OF THE INVENTION
In view of this, the inventor has devoted research effort and discovered that by placing vacuum equipment at the side of patients' beds, the dirty air breathed out from the patients' lungs and mist spit out from the mouths will be inhaled by the said vacuum equipment and clean air will be released from the equipment after filtering. Consequently, the possibility of contracting infectious diseases from hospitals will be lowered.
For these reasons, the main objective of this invention is to provide vacuum equipment for medical tables that primarily comprises a universal arm, inhaler masks that are attached separately to two sides of the tube and a vacuum cleaner. This equipment has primarily placed inhaler masks at the side of patient's mouth, then, through the vacuum cleaner, the mist that surrounds the patient's mouth will be inhaled and clean air is released after filtering, consequently, the possibility of contracting infectious diseases is lowered.
Another objective of this invention is to provide a vacuum equipment for medical tables which has attachable and disposable inhaler masks. The inhaler masks are disposable and will not infect other persons because of having contact with the patients.
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.
