Definitions

  • the present invention generally relates to equine nasogastric tubes, and particularly to such a tube with an image capturing device.
  • Nasogastric intubation is an essential and possibly life-saving procedure performed in cases of equine colic.
  • a nasogastric tube is passed in the ventral meatus, and carefully turned and directed past the ethmoidal area and pharynx toward the esophagus. The horse is stimulated to swallow, and the tube is then pushed in the esophagus. Blowing into the tube to dilate the esophagus can help facilitate insertion. After the tube is in place, there may be spontaneous reflux. If there is no spontaneous reflux, then the stomach should be lavaged. Medication should never be administered by a nasogastric tube to a horse with colic without checking first for reflux.
  • the present invention seeks to provide an improved equine nasogastric tube with an image capturing device, as is described more in detail hereinbelow.
  • the equine nasogastric tube has all the functionality of a regular equine nasogastric tube, such as but not limited to, evacuation of fluids, gas and ingesta from the stomach, as well as introduction of fluids and medicines into the stomach, with the added advantage of visual inspection of the esophagus, stomach and other internal structure along the way.
  • apparatus for use with an equine animal having a stomach, including an equine nasogastric tube including an image capturing device at a distal end thereof, wherein an inner lumen diameter of the tube is sized to allow evacuation of fluids, gas and ingesta from the stomach, as well as introduction of fluids and medicines into the stomach.
  • the image capturing device can be, without limitation, a camera, video camera, ultrasound probe or X-ray sensor, for example.
  • a connector is at a proximal end of the tube for communicating image data from the image capturing device to a processor.
  • the connector is automatically released in case the animal suddenly pulls away.
  • a light source illuminates the stomach.
  • a system may be provided for cleaning the image capturing device.
  • a sensor is provided that senses a vital sign, the sensor being attached to a distal end of the tube.
  • Fig. 1 is a simplified illustration of an equine animal, with an equine nasogastric tube inserted in the nostril, in accordance with an embodiment of the present invention
  • Fig. 2 is a simplified illustration of the equine nasogastric tube, constructed and operative in accordance with an embodiment of the present invention
  • Fig. 3 is a simplified close-up illustration of a distal end of the equine nasogastric tube, in accordance with an embodiment of the present invention.
  • Figs. 4 A and 4B are further simplified illustrations of the distal end of the equine nasogastric tube.
  • FIG. 1 illustrates an equine animal 11 with an equine nasogastric tube 10 inserted in the nostril 9, in accordance with an embodiment of the present invention. Veterinarians and other personnel assisting in the procedure are not shown for the sake of simplicity.
  • tube 10 is passed in the ventral meatus, using the thumb to keep it directed correctly. Care is taken not to enter the false nostril. Once the pharynx is felt, tube 10 is turned 180° to direct the curvature dorsally toward the esophagus. The horse is stimulated to swallow, and tube 10 is then pushed in the esophagus.
  • Equine nasogastric tube 10 is a soft hollow tube, comprising an image capturing device 12 at a distal end thereof (distal referring to the end inserted into the animal).
  • Image capturing device 12 may include, without limitation, a camera, a video camera, ultrasound probe, X-ray sensor or any other kind of sensor or transducer for acquiring images.
  • Fig. 1 a camera, a video camera, ultrasound probe, X-ray sensor or any other kind of sensor or transducer for acquiring images.
  • the cross-sectional area of a lumen 15 for the passage of liquids is much greater than the cross-sectional area of image capturing device 12 (e.g., the cross-sectional area of the lens) (e.g., without limitation, twice as large, or five times as large or ten times as large and other relationships).
  • Image capturing device 12 sends images of the stomach or other internal structure through wires 14 located inside the tube wall.
  • the proximal end of tube 10 has a connector 16 for communicating the image data from image capturing device 12 to a computer, display or any kind of processor 18 (the term "processor” is used to designate any kind of computer, display or other device for processing, storing and displaying information from the images).
  • the processor can be at the distal end or any other location, or it may be external to the animal.
  • Connector 16 is designed to automatically release in case the animal suddenly pulls away in a direction away from processor 18.
  • Connector 16 (and the image capturing device 12) can be wireless (e.g., BLUETOOTH, RF, infrared, etc.).
  • the inner lumen diameter of tube 10 is large enough to allow evacuation of fluids, gas and ingesta from the stomach, as well as the introduction of fluids and medicines into the stomach.
  • the image capturing device 12 enables continuous monitoring of the level of liquids, such as in prolonged treatment of colic wherein the tube may remain in the stomach for several hours, or in the case of intestinal inflammation (e.g., small intestine proximal enteritis with ileus) wherein the tube may remain in the stomach for several days and checked from time to time for possibly performing reflux evacuation.
  • intestinal inflammation e.g., small intestine proximal enteritis with ileus
  • the image capturing device 12 also enables continuous monitoring in cases wherein the tube is left in the stomach for several days in order to introduce food, nutrients, liquids, medicine or other substances into the animal. For example, some horses may have difficulty eating because of a traumatic event, surgical procedure (e.g., in the throat or GI tract), nerve paralysis (e.g., due to tetanus), or general weakness (e.g., foals, with sepsis). In all these cases, there is a danger of developing gastric reflux.
  • the image capturing device 12 enables early and definitive detection of accumulation of liquids in the stomach.
  • the image capturing device 12 can also serve as a diagnostic tool of disorders in the stomach, which in the prior art is done with a special gastroscope for horses, which is much more expensive than the device of the present invention.
  • an adjunct light source 20 may be provided which allows good visualization of the equine stomach.
  • a system 22 may be provided for cleaning the lens, allowing good quality picture in dirty conditions.
  • System 22 may include a lumen through which a cleaning fluid (e.g., water) flows onto the lens to clean it.
  • a cleaning fluid e.g., water
  • the imaging angle of image capturing device 12 can be controlled mechanically or electrically to achieve complete imaging of the stomach.
  • Sensors 24 for vital signs detection can be attached to the distal end of tube 10 to allow constant monitoring. Vital signs can be displayed on the display. An alarm can be sent if the vital signs exceed a given level.
  • a pH sensor can be attached to the distal end of tube 10 and the ph values of the stomach contents can be presented on the display.
  • a volume and/or depth sensor can be attached to the distal end of tube 10. This sensor constantly measures the depth and/or volume of the stomach contents. Depth and/or volume can be presented on the display. An alarm can be sent if the depth and/or volume exceed a given value.
  • the device of the present invention provides a definitive and novel way to ensure that a nasogastric tube has been introduced into the alimentary tract and not into the lower respiratory tract.
  • the device of the present invention provides a novel procedure for diagnosing accumulation of fluids and ingesta in the equine stomach during a colic episode.
  • the device of the present invention provides a novel procedure for treating horses or other equine animals suffering from an accumulation of fluids or ingesta in the stomach during a colic episode or during other conditions.
  • the device allows the veterinarian or technician to direct the tip of the tube into the stomach contents, empty them by siphon or with suction and confirm that the stomach has been completely emptied (in contrast to the blind attempts of the prior art).
  • the device of the present invention provides a novel procedure for constant monitoring and treatment of horses or other equine animals with small intestine ileum, as opposed to the prior art wherein horses are left with the stomach tube for hours or days and a blind attempt for gastric evacuation is performed every few hours.
  • the present invention provides a definitive device and method for early recognition of stomach accumulation, and an efficient method of emptying the stomach if needed.
  • a volume and/or depth sensor at the distal end provides constant monitoring of the fluids level. An alarm is sent if the depth and/or volume exceed a given value, giving the caretakers an immediate alert to the condition.
  • the device of the present invention provides a novel procedure for diagnosis and treatment of "choke” (esophageal impaction) in equines.
  • the present invention enables a direct visualization of the obstruction, and enables introduction of fluids exactly into the impaction and a direct visualization of the outcome of the treatment. Since these cases have a high risk of developing mucosal ulcers or esophageal rupture, the device provides an early recognition of these life threatening conditions, without the current need of additional endoscopic examination.
  • a shorter version of the device can be used as a uterine catheter with a video camera or other image capturing device at the distal end. The uterine catheter with camera can be used to perform uterine lavage under direct visualizing.
  • the uterine catheter with camera can be used to identify the utherotubal junction.
  • the uterine catheter with camera can be used as a guide for an insemination pipette for the procedure of deep uterine horn insemination.
  • the uterine catheter with camera can be used as a guide and a sleeve for other instruments, providing a method for taking diagnostic samples from the endometrium or for removal of endometrial cysts or removal of other endometrial masses.
  • the nasogastric tube may be left in the horse or other equine animal for a while, e.g., in some cases for hours or days. In such cases, many horses constantly try to pull the tube out.
  • the prior art uses adhesive tapes for attaching the tube to the halter in an effort to combat this problem.
  • the present invention provides a novel solution to this problem.
  • a proximal portion of equine nasogastric tube 10 is affixed to a halter 26 with a clip 28.
  • Clip 28 may have elastic arms with a U-shape. The tube 10 is pressed into the clip 28 and the elastic arms snugly hold the tube in place. This is significantly easier and quicker than the prior art, and more reliable.
  • a preferred position for clip 28 is on the cheekpiece of halter 26.
  • clip 28 may be positioned on other places of halter 26, such as the nosepiece, chinpiece, tie ring, connecting strap, throatlatch (the non-limiting illustrated position), or crownpiece.
