DETAILED DESCRIPTION OF THE INVENTION
[0027] The present suction device 10 can be portable and include a hand piece 12 including a barrel portion 14 and grip portion 16 (e.g., handle). The grip portion 16 is configured for a user to grasp the device 10. The grip portion 16 can contain a housing 18 to receive a battery 20 (e.g., a battery pack magazine). The device 10 can also include a motor connected to the battery 20, wherein the motor is configured to create the vacuum and draw in fluid and/or gas through the barrel portion 14 into a fluid reservoir 30. The device 10 can include an impeller connected to the motor that can be positioned above the hand piece 12 to create the vacuum for suction.
[0028] The fluid reservoir 30 is a container in fluid communication to the suction tube 34, wherein the reservoir 30 can receive and collect the suctioned fluid and/or gas. The fluid reservoir 30 can be positioned below the barrel portion 14 and in front of the grip portion 16. Alternatively, the fluid reservoir 30 can be positioned behind the grip portion 16.
[0029] The present device can be configured in a variety of ways, including, but not limited to, the illustrated configurations in the figures. FIGS. 1-5 illustrate schematics for a variety of mechanical configurations. FIGS. 6A-9B illustrate a variety of different structural configurations.
[0030] As shown in FIG. 1, the device 10 can include two separate intake portions including a gas intake 60 and a fluid intake 62, wherein the gas intake 60 can be in communication with a HEPA filter 64 and/or turbine fan 66. The fluid intake 62 can be in communication with a pump 68 (e.g., peristaltic pump), a fluid reservoir 30, and a tank pressure vent 72. Advantages of the separate fluid and gas intakes include having specialized pumps, one for each medium, reducing consumption of power when only one medium needs to be suctioned, and quieting suction noises.
[0031] FIG. 2 illustrates a combined fluid and gas extraction device. Both the gas and fluid are combined in one intake 61 that is in fluid communication with the fluid reservoir 30, a HEPA filter 64, and turbine 66 to produce a filtered air output 74. The combination of gas and liquid intake simplify and streamline the components of the device.
[0032] FIG. 3 is an example of a combined gas and fluid intake 61 in communication with the fluid reservoir 30, the HEPA filter 64, and a piston pump 68 positioned after the fluid reservoir 30 to create an output of filtered air 74.
[0033] FIG. 4 is another example of combined gas and fluid intake 61 in communication with the fluid reservoir 30 and the HEPA filter 64 positioned after the reservoir 30 to create an output of filtered air 74, wherein a peristaltic pump 76 is positioned before the fluid reservoir 30. The device 10 may include a small turbine fan to suction air.
[0034] FIG. 5 is an example of the device 10 having combined gas and liquid extraction including a compressed air intake 84. In the example, the device 10 includes a single gas and fluid intake 61 in communication with a venture valve 82, a fluid reservoir 30, and an air filter 64. In addition, the device 10 includes a compressed air intake 84 in communication with the venture valve 82 and air compressor 80. Such configuration isolates the motor from the fluid path. Advantages of a configuration including the venture valve 82 include increased quietness, high suction pressure, separate motor and fluid path.
[0035] FIG. 6A illustrates a device 10 having a single fluid/gas intake tube 64, a fluid reservoir 30, and a handle portion 16 containing the power source (e.g., battery 20).
[0036] As shown in FIG. 6B, the device 10 can include an optional bypass port to bypass canister and connect up to wall mounted or floor mounted suction for high volume cases or rapid increase in blood loss. The device 10 can include a sliding indwelling suction tip 86 to allow for a user to change the length of the suction tube 34. The sliding indwelling suction tip 86 can include laser lines for measurement purposes. The device can include a suction selector 90 on the handle portion 16 to select from gas or liquid suction.
[0037] FIGS. 7A-7B illustrate an example of the device 10 wherein the fluid reservoir 30 is contained within or below the handle portion 16 of the device 10. In such example, the battery pack 20 is connected to the back end of the pistol portion 14. The device 10 can include a dual trigger 92 on the handle portion 16 to select from gas or liquid suction.
[0038] FIGS. 8A-8B illustrate a configuration of the device 10 wherein the handle portion 16 and pistol portion 14 are approximately linear, wherein a suction tube 34 can connect to an end of the handle portion 16 that can be connected to a portable pump or permanent pump.
[0039] FIGS. 9A-9C illustrate perspective and exploded views of an example of the device 10 including a fenestrated handle portion 16 to allow direct visualization of the fluid canister 30. The configuration is light weight and includes a counter-balanced Li-ion battery 20 or supercapacitor. The device 10 can include a bypass valve for an in-wall-suction and/or a separate floor-mounted suction source. As shown, different size fluid canisters can be incorporated and exchanged depending on the situation. The example includes the fluid canister 30 within the handle rather than extending from the barrel. The fluid canister 30 can be released via an ambidextrous thumb magazine release mechanism. The device 10 can also use interchangeable ULPA and debris filters, quick connect interchangeable suction tips, magnetic clasp connections for canisters with a seal, an ergonomic in-line pistol grip. The device 10 can include a sliding indwelling suction tip 86 to allow for a user to change the length of the suction tube 34, wherein the suction tip 86 is attached with the connectors 87 (e.g., washer and bolt).
[0040] The handle portion 16 or pistol portion 14 can include a light source 32 (e.g., LED) to illuminate the operative field, wherein the light source 32 can be controlled via a switch and/or dial on the trigger. The device 10 can be a cordless piece with a battery pack 20 and a removable fluid canister 30.
[0041] It should be noted that various changes and modifications to the embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages. For example, various embodiments of the systems and methods may be provided based on various combinations of the features and functions from the subject matter provided herein.
