Description




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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




As illustrated in

FIG. 1

, this invention of vacuum equipment for medical tables mainly comprises a universal arm


10


, a spotlight


41


secured to the end of universal arm


10


, disposable masks


63


that are respectively attached to the end of tube


62


and vacuum device


30


.




The universal arm


10


is assembled by several hollow pipes


11


. The joint between two pipes


11


can be bent to the appropriate angle so that the front end and the back end of the universal arm


10


can be adjusted to any coordinates that is within a suitable distance. The end of universal arm


10


is either attached to stand post


40


or installed at one side of table


50


. Also, a pipe


11


is attached to the front end of universal arm


10


and connected to the spotlight


41


. The disposable mask


63


can be adjusted to various angles through tube


62


. The interior of tube


62


is smooth and glossy in order to maintain the tube clean and to avoid noise in the tube. The vacuum cleaner


30


has an air inlet


31


as shown in

FIG. 7. A

motor M is connected to the air inlet


31


and there is a fan


32


at the output of motor M. In addition, the partition nets


33


have divided the interior of vacuum cleaner


30


into several compartments. There are many holes on these partition nets which allows passage of air from one compartment to another. Beneath fan


32


is water and dirt reservoir compartment


34


. After the above mentioned fan


32


is operated, the produced inhalant whirlwind will collect together impurities and dirt to the water and dirt reservoir compartment


34


, the compartments beside the water and dirt reservoir compartment


34


are arranged in order as filter


35


, ultraviolet rays


36


, and active carbon


37


. These compartments have filter materials that will filter impurities drawn in by the fan


32


. The last section is an air outlet


38


that releases clean air.




This equipment is designed such that the important universal arm


10


is attached to stand post


40


so that the equipment can be integrated directly with the table


50


in production or installed to the side of table


50


.




The other embodiment of this invention is shown in FIG.


2


-

FIG. 5

, in order to satisfy various different needs, this invention also can integrate mask


20


and spotlight


42


on stand post


40


into one piece. The tubes that connect the part to vacuum source


30


are hidden inside the post. When the spotlight


42


approaches the patient


60


, the integrated equipment and the non-integrated one will show similar effects.




As shown in

FIG. 2

, when this invention is used in practice, the universal arm


10


will be twisted and the mask


20


is shifted right to the front of patient


60


. When the dentists treat the teeth of patient


60


or the doctors diagnose their patients, the saliva and blood spit emanating from the patients' mouths will be sucked into the vacuum cleaner


30


by mask


20


(as shown in FIG.


7


). As explained earlier, the operation of fan


32


will produce a whirlwind which then causes the blood and saliva to hang on the surface of walls and gather together at water and dirt reservoir


34


. Thereafter, the remaining little impurities will be filtered, disinfected, and deodorized by passing through filter


35


, ultraviolet rays


36


, active carbon


37


, and the clean air will be released fmally. For illumination purposes, a spotlight comprising a bulb


42


and a reflector


39


are mounted on the mask


20


. The mask may be one that is disposable.




From the above descriptions, it is understood that since this invention is designed for the use in various working environments, and hence, it may have a variety of designs. For example, the universal arm may be mounted to a stand post, or the universal arm may be installed at the side of the table. The mask and spotlight may be integrated together. These modifications are inventive and practical to satisfy the different environments.




From the above description, this invention is used to remove bacteria that is produced and spread over the air in the process of treating patients so that the hygiene safety for doctors and staffs as well as the hygiene inside hospitals can be improved. Consequently, the rate of infection will be reduced.
