DESCRIPTION OF THE PREFERRED EMBODIMENTS For a detailed description of the construction and utilization of the device, reference is made to the attached drawings. FIG. 1 illustrates a simulated use of the Stemach tube 10 in a bovine. Stomach tube 10 is approximately one inch in diameter and seven to ten feet long. These dimensions are optional and for utilization on younger cattle a shorter tube of smaller diameter might well be employed. The loop belt-type species of the device is illustrated principally in FIG. 2. This device is constructed with an outer case 11 comprising a rubber or plastic flexible tube one inch in diameter. Each species of the device is driven by electrical power supply means 12 which includes an integral speed control mechanism 13. The speed control 13 is an important element of the device in that the speed at which the evacuating mechanism is operated must be adjusted to a satisfactory level while evacuating the stomach of a bovine to accomplish the desired results and avoid injury to the animal. Speed control 13 may be of any variety of speed controls used in conjunction with electric motors. Speed control mechanism of the type utilized with electrical drills or electrical mixers might be employed. The stomach tube 10 of the endless belt species of the device is constructed with an outer case 11 and a small diameter belt tube 14 secured to the interior surface of the outer case 11. At the forward or left end of the device as illustrated in FIG. 2 adjacent the end of belt tube 14 is mounted an idle pulley 15 rotatably mounted on an idle pulley shaft 16 which is secured to outer case 11. Adjacent the discharge end or right end of the device as illustrated in FIG. 2 is mounted a drive pulley 17 which is secured to a drive pulley shaft 18. This drive pulley shaft 1 8 is interconnected to electrical drive motor 19 through a reduction drive gear 20. An intake opening 21 is formed in outer case 11 generally adjacent outer pulley 15. The opposite end of the device in the vicinity of drive pulley 17 is constructed a discharge opening 22. Belt 23 may be constructed of rubber or other plastics reinforced with nylon filaments to reduce stretching; mounted on this belt 23 is a series of belt cups 24 comprising a device resembling a miniature bucket conveyor. These cups 24 should be of soft plastic or rubber material having flexible characteristics. This quality is necessary to permit the moving of belt 23 carrying cups 24 through belt tube 14 in the direction of the forward end of the tube. As the belt moves around idle pulley 15 the cups open and flare conveying liquid and material from intake opening 21 toward discharge opening 22.
For a description of the construction and operation of the species of the device employing an auger-type conveyor reference is specifically made to FIGS. -8. With specific reference to FIG. 5 in this embodiment stomach tube is constructed with an outer case 11 substantially of the diameters and configuration previously stated. This species of the device is constructed with an intake opening 21 and a discharge opening 22 in a manner quite similar to species of the device illustrated in FIG. 2. Mounted for rotation inside outer case 1 1 of the species of the device in FIG. 5 is an auger conveyor 27. This device comprises a spiral-like conveyor constructed of semi-stable rubber or plastic secured to and spiralling around an auger conveyor shaft 28. This conveyor shaft 28 is rotatably mounted in a forward bearing 29 adjacent intake opening 21. To the drive or discharge end 22 of this structure there is secured a rear bearing 30 in which the auger conveyor shaft 28 is mounted for rotation. Conveyor shaft 28 projects through outer case 11 by means of a short rigid drive shaft 31 terminating in a drive member 32. This species of the device might preferably be constructed with intermediate bearing members 33 at one or more points intermediate for forward bearing 29 and rear bearing 30. The purpose of these intermediate bearing members is to support the auger conveyor shaft 28 at the center of the outer case 11 to minimize the contact by the auger conveyor 27 with the interior surface of outer case 11. The drive mechanism of the device of FIG. 5 is substantially as illustrated in fragmented view of FIG. 6. A hand held detachable drill-like mechanism is employed. This power supply means 12 might well comprise either a direct current or alternating current motor. It can be self-contained, utilizing a rechargeable storage battery as used in portable drills and lawn clippers. The device is preferably constructed with a very low ratio reduction drive gear to reduce the rotation of the output to drive member 32. This device should also be constructed with an adjustable speed control 13 permitting the revolutions per minute (rpm) to be varied to accomplish optimum rotation of the auger conveyor shaft 28 to protect the animal being treated as well as insure the desired rate of evacuation of the stomach of a bovine.
OPERATION In the operation of the device of this invention the primary veterinary application is to evacuate the stomach of ruminants who have ingested excessive amounts of food causing a bloated, distressed condition of the animal. The device of this invention also is particularly suited for evacuation of the stomach of an animal having ingested poison or toxic substances. A wide variety of stomach tubes 10 have been developed and utilized by veterinarians. The primary advantage of this device is the powered rapid evacuation of the contents of the stomach of the animal. In utilization of stomach tube 10 reference is made to FIG. 1. The animal is forcibly restrained or tranquilized and the tube is inserted through the esophagus utilizing accepted veterinary procedures. Pressure is applied to tube 10 projecting the forward end or intake end 21 into the animal a sufficient distance to project into the stomach of the animal. When this is accomplished the activation of power drive means 12 of the species of the invention illustrated in FIGS. 1-4 and drive pulley 17 rotates belt 23 carrying belt cups 24 moving fluids or grain from the intake opening 21 and discharging it through discharge opening 22.
A similar result is obtained in utilizing the device of FIG. 5. The animal is secured or restrained and tube inserted through the esophagus into the stomach of the animal. A rotation of conveyor shaft 28 through the drive member 32 will again evacuate the stomach of the animal being treated. In this regard it is pertinent to note that after an evacuation of the stomach of the ani mal fluids can be injected into the stomach of the animal through reversing the procedures through discharge opening 22 and intake opening 21 fluids can be placed in the stomach of the animal and repeated evacuated to purge or remove toxic substances from the animals stomach.
