FIELD OF INVENTION
This invention relates to dental / medical aspirator or suction used to suck fluid or clot from operating site.
PRIOR ART
Existing all types of suction require electricity of 250-2000 watt for their operation. There are two types of dental suction namely, pneumatic suction and motorized suction. Pneumatic suction works on air mechanism in which air passes through three pipes interconnected to each other giving rise to T-shape.
Motorized suction is a specially designed motor, which creates vacuum using which pump sucks fluid.
Drawbacks associated with the prior art can be listed herein below:
Consumption of considerable amount of electrical energy.
Inoperable through normal inverter.
Creation of noise in working mode.
Larger in dimension, which occupies more space.
Very costly.
OBJECTS OF THE INVENTION
The primary object of the present invention is to propose dental / medical aspirator or suction used to suck fluid or clot from operating site which overcomes disadvantages associated with the known art.

Another object of the present invention is to propose dental /medical aspirator or suction used to suck fluid or clot from operating site which is operable through normal house hold inverter and consumes nominal electricity of 15-20 watt.
Further object of the present invention is to propose dental aspirator or suction used to suck fluid or clot from operating site which does not create noise in operational mode.
STATEMENT OF INVENTION
According to this invention, there is provided a dental/medical aspirator or suction used to suck fluid or clot from operating site comprising of a water tank provided with a submersible pump connected to a suction pipe.
BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWING
Further objects and advantages of this invention will be more apparent from the ensuing description when read in conjunction with the accompanying drawing and wherein:
Fig. 1 shows the present invention.
DETAIL DESCRIPTION OF THE INVENTION WITH REFERENCE TO
THE ACCOMPANYING DRAWING

The present invention discloses a dental/medical aspirator or suction used to suck fluid or clot from operating site as shown in fig. 1 comprises of a water tank provided with a submersible pump connected to a suction pipe.
The pump is having a water inlet and water outlet. The outlet is connected to a pipe, which is extended to a fluid collecting bottle containing fluid from the operating site. Said pipe creates negative pressure to suck the desired fluid of operating site.
The pump sucks water through water inlet and expels water through water outlet. When water flows through water outlet then said pipe acts as an aspirator which starts sucking.
The pipe connected to said outlet of pump can be provided in flow communication with the fluid of the operating site without the fluid collecting bottle in between.
The water level in tank is kept at such depth that the outlet pipe is slightly dipped into water.
The suction capacity can be increased or decreased by increasing or decreasing velocity of water and diameter of outlet.
It can be used independently or by adding into other available suction mechanism.

The submersible pump used in suction is provided with two numbers of connected pipes, one is water inlet pipe and another is water outlet pipe. At water outlet pipe, an extra pipe is attached with T-section pipe at exit point of the water outlet pipe.
During operation of device, pump sucks the water from vertically situated water inlet pipe and pumps water forcefully out from the motor through the water outlet pipe (horizontally situated). When water flows through this water outlet pipe, extra connected pipe acts as an aspirator and starts sucking air from this extra pipe due to creation of negative pressure.
It is to be noted that the present invention is susceptible to modifications, adaptations and changes by those skilled in the art. Such variant embodiments employing the concepts and features of this invention are intended to be within the scope of the present invention, which is further set forth under the following claims:-

CLAIM;
1. A dental/medical aspirator or suction used to suck fluid or clot from operating site comprising of a water tank provided with a submersible pump connected to a suction pipe.
2. A dental/medical aspirator or suction as claimed in claim 1, wherein said pump is provided with a water inlet and water outlet in which said outlet is connected to a fluid collecting bottle containing fluid from the operating site through a pipe creating negative pressure.
3. A dental/medical aspirator or suction as claimed in claim 2, wherein said outlet of the pump can be provided in flow communication with the fluid of the operating site.
4. A dental/medical aspirator or suction as claimed in any of the preceding claims, wherein said water outlet pipe is connected with a T-pipe at its exit point.
5. A dental/medical aspirator or suction used to suck fluid or clot from operating site substantially as herein described with reference to the accompanying drawing.
