Definitions

  • the present subject matter relates to, a medical device and, in particular, to a device for enteral tubes.
  • enteral feeding refers to delivery of nutrient-rich liquid to a patient through an enteral tube inserted directly into a gastrointestinal (GI) tract of the patient.
  • GI gastrointestinal
  • the enteral tube is inserted through the patient's nose or nasal cavity, down the throat into esophagus, and further into stomach or small intestine of the patient, to assist the patient in feeding and for providing nutrition.
  • the enteral tube can also be used to remove poisonous substances from the stomach or to deliver medicine to neutralize a potentially dangerous substance in the stomach or intestine. Further, the enteral tube can be used to remove an intestinal obstruction or blockage that may be causing pain, discomfort, and swelling to the patient.
  • Enteral tube feeding can be used for different segments of medical conditions taken together such as. Neurological Dysphagia which also includes conditions which are different from the ones listed above, , throat, and esophageal etc.. Comatose patients, ICU patients, unconscious patients with some underlying medical condition, advanced dementia and Amyotrophic Lateral Sclerosis (ALS) patients, Gastric bleeding that is severe, an entereal can be used to flush cold saline into and out of the stomach to staunch the bleeding. If the person has a lot of gastric distention the NGT can be used as a vent or a drain and be placed to gravity drainage or suction. Similarly, enteral tube feeding may also be used in critical conditions including critically ill or injured patients requiring mechanical ventilation. Neuromuscular disorders including muscular dystrophy, spinal cord defects, cerebral palsy, and AALS or Lou Gehrig's disease may also include situations where enteral tube may be utilized.

  • enteral feeding In certain cases, patients having difficulty in eating or drinking either due to a surgery or because of some health problem are advised enteral feeding.
  • enteral feeding an enteral tube is inserted directly into the GI tract of such patient.
  • the enteral tube is inserted through the patient's nose or nasal cavity, down the throat and esophagus, and further into the stomach or the small intestine, without knowing the true location of the enteral tube after insertion.
  • This procedure of placement of enteral tube is commonly known as a blind placement procedure.
  • Use of such blind placement procedures have to be handled by very high skill practitioners to insert the enteral tube into esophagus of the patient, and the patient is at a risk of serious injury. Further, during such procedure, there is risk that the enteral tube may go into the lungs of the patient. This may lead to difficulty in breathing and other health problems may arise.
  • X- rays are used to visualize the blindly inserted enteral tube.
  • use of such technique typically requires at least 5 to 6 X-ray scans to confirm the location of the enteral tube, as each time the enteral tube is inserted blindly.
  • Such persistent exposure to X-rays throughout the treatment of the patient gives rise to serious concern, as the high levels of radiation may have harmful effects on the patient.
  • An additional disadvantage for using the X-ray technique to confirm enteral tube placement is that the equipment necessary to perform the technique is typically available only in hospitals and thus is of no help to in-home-care patients. Further, to repeatedly verify proper placement of the enteral tube in this manner is cumbersome, time consuming, and expensive.
  • CO 2 carbon dioxide
  • a sensor attached to an end of the enteral tube changes color in the presence of (CO 2 ). thus indicating that the enteral tube may have entered the airway. If the enteral tube is in the airway then the enteral tube should be removed.

  • the device 100 directs the enteral tube 508 to pass through the longitudinal opening such as the rectangular opening or the trapezoidal opening to the lower opening of the insert member (not shown in the figure 6(c).
  • the lower opening may be inclined at a predetermined angle from the longitudinal axis of the holding member and the interior of the lower opening may be a curved surface.
  • the lower opening inclination directs the enteral tube 508 towards posterior wall esophagus of the patient.
  • the device 100 can be taken out from the mouth of the patient.
  • the enteral tube 508 may further be inserted down the esophagus, into GI tract, i.e., into the stomach or the small intestine of the patient, to assist in feeding and to provide nutrition.
  • the device 100 is designed in such a way that when the enteral tube 508 falls on the insert member, it gets directed towards the esophagus and allows accurate insertion of the enteral tube 508 into Gl tract of the patient.
  • the enteral tube 508 can be accurately, easily, and painlessly inserted into the GI tract of the patient without requiring invasive techniques.
  • the configuration and operation ensures that the enteral tube 508 is not inserted into trachea, therefore preventing the aggravations of the condition.
  • the device 100 is easy to handle and does not require specific training for operating the device 100. As a result, even a considerably less skilled medical practitioner can access the device 100 for inserting the enteral tube 508 into GI tract of the patient.
  • the ergonomically designed of such device 100 is suitable for aiding the insertion of the NG enteral tube 508 in the mouth-oesophageal junction of the patient.
  • Such device 100 can be referred as an 'ACCUFEED device'.
