SW72 AT'TO RN PORTABLE SUCTION PUMP SYSTEM BACKGROUND OF THE INVENTION THE INVENTION The pumping system herein designed is portable, and because, of its component parts and their arrangement, is capable of providing various combinations of suction and flow, as required in medical use and especially in the field and is capable of operation from various power sources.
THE DRAWINGS FIG. 1 is a diagrammatic illustration of the vacuum circuit of the system of this invention; and
-' FIG. 2 is an electrical schematic associated with the system.
THE PREFERRED EMBODIMENT Looking at the drawings, there is diagrammatically illustrated the suction or vacuum part of the system in FIG. I and the electrical part of the system in [0. 2. In the system, a DC motor ll is coupled to a suction pump 12 preferably of the vane ,type in which the vanes and rotor are carbon and the remaining parts are constructed of corrosion resistant materials. In order to eliminate some servicing (except for periodic cleaning of the pump), the pump is preferably constructed with bearings which are grease lubricated for life. The carbon vanes also require no lubrication. While this general type of pump is preferred, other types of suction pumps can be used in the system if necessary or desirable. The motor 11 can-be energized by battery or from an external power source, as will later be described. I
. Thesuction or vacuum part of the system includes, in addition to the pump 12, a noise muffler 13 connected to the out let of the pump by a conduit 14, and a bottle or container 15 connected to the inlet of the pump by a conduit 16. A conduit 17 from the bottle 15 permits selective coupling of the bottle 15 to a pumping field. The bottle or container 15 acts as a suction orvacuum reservoir as well as a container for drain fluids, as will be described. I
In the line 16, there are an air filter and trap 18, a check valve 1 9, a vacuum regulator 20, a vacuum gauge 21-, a vacuum switch 22, a float valve 23, and a pressure vent valve 24.
The check valve 19 and the pressure vent valve 24 are of conventional construction. as for example a spring biased ball or member which when seated prohibits the passage of fluid there through and which when unseated permits the discharge offluid in one direction.
The 'floatvalve 23 is also ofconvent ional construction. For example, the valve may contain a float in a container which will block flow through a conduit when the fluid in the containerv reachesa certain'level.
The vacuum regulator 20 is also of conventionalconstruction inthat it contains an adjustable orifice, as forexamplea biased ball and a seat with meansto adjust'the bias. force.
Likewise, the vacuum switch 22 is of conventional'construction and includes adiaphragmconnected to a switch means, such that changes in the vacuum level'in the system cause actuation of-the switch means.
Because the variousparts are of conventionalconstruction, and well known in the art, no further detailed description is considered-necessary, it being understood that various constructions other than that described above could'be used'if their functions are equivalent.
In operation, the motor 11 effects rotation of the rotor (not shown) of the pump 12 resulting in the exhaustion of air through the noise muffler 13. To permit both a preselected suction limit in the bottle or container 15, as well as cyclic operation when necessary or desirable, other elements are included in the flow line or conduit 16. The vacuum regulator 20 permits the selection of a vacuum level at the bottle 15 by bleeding outside air into the system. at the selected level of vacuum and thus preventing excessive vacuum level. A vacuum switch 22 controls the energization of the motor 11 for cyclic operation, switching the motor on at a low value of vacuum and switching the motor off at the preset value, both values being factor set, while the vacuum gauge 21 indicates, for visual observation, the level of the vacuum in the bottle 15.
Accordingly, once thebottle 15 is evacuated to a'selected level, and air is'not permitted to enterthe system through the line or conduit 17, the level of vacuum in the bottle 15 remains, even through air flows to the pump 12.
The float valve 23 prevents fluid which has been collected or is collecting in the bottle 15 from travelling from the bottle to the pump 12. Thus, even if the container 15 is overfilled with fluids, and fluid reaches the float valve, the valve prevents flow of these fluids to the pump 12 by closing the conduit 16 to the pump.
Under certain circumstances, for example in pleural cavity suctioning, a pressure can be developed in the pumping field when a person breathes if the vacuum pump is not operating, which pressure must be vented to the atmosphere. Also, in the event of sudden reduced atmospheric pressure, as in the case of an aircraft pressurized cabin rupture, fluids may be forced back into the patient if the pressure difi'erential is not relieved. For these functions, the pressure vent valve 24 is provided.
Attention now directed to FIG. 2 of the drawings showing the electrical part of the system being described. This part includes the motor 11 connected through a three-position ganged selector switch 25 to alternative power sources, i.e., an internal battery 26 or to an external source (not shown) through a case plug 27. Between the positive side of the power source and the motor is an off-on switch 28. Preferably, the internal battery is rechargeable, as for example of the silver cadmium type. The external power supply unit, one which can be operatedfrom an AC source but which will supply DC to the motor 11 and regulated charging power to the battery. External power can also be any source of DC of correct voltage.
As is illustrated, the selector switch 25 has three positions. When in the No.1 position, currentis supplied from the external power source and also'the battery is charged if connected to a combination-battery charger power supply.
When in the NO. 2 position, current is supplied by the battery 26. This circuit includes an elapsed time timer 29 which indicates the length of time the system has been operating on the battery 26 and which indicates to the operator a need for battery recharging. The battery circuit includes a low voltage cutofl switch 30 which is responsive to battery voltage and which will cut off the motor 11 when the voltage is below a predetermined level, to prevent damage to the battery 26. During startup when using the battery, a switch 28A is mementarily closed to activate the low voltage switch. A mode switch 31, movable betweenopen and closed positions in- In-order-to indicate to the observer whether or not the unit is. in operation, a pilot light 32 is connected in parallel to the motor I1.
Attesting tothe portability of a unit incorporating the variousparts'enumerated, a self-contained, battery operated unit is'hou'sed in a shock-resistant aluminum case which is water tight when closed. Typical dimensions of such a case are 9 inches X 9%inches X l3 inches. Using a 20 volt battery pack of six 3.3 volt silver-cadmium batteries, rated 5.0 ampere hours, new batteries will provide about seven hours operation at a inch suction value. In the cased system, the collection container is capable of holding about 1600 cc of fluid. Such a unit weighs about I? pounds. 1
