Description

Technical Field

[0001] The utility model relates to the technical field of guiding forceps, in particular to a guiding forceps for inserting a nasogastric feeding tube. Background Art

[0002] Currently, nasogastric tube insertion mainly relies on blind insertion by nurses. Critically ill patients in the ICU often encounter various difficulties in tube insertion, leading to tube insertion failure. Repeated blind tube insertion is prone to complications such as mucosal bleeding, misplaced tracheal insertion, and skull base injury. Operation failure will also cause waste of medical supplies and affect the patient's treatment. When ICU nurses encounter difficulties in blindly inserting a nasogastric tube in critically ill patients, doctors will choose to use a laryngoscope through the mouth to help expose the esophageal opening in the throat, and use a fiber bronchoscope to guide or clamp the nasogastric tube with hemostatic forceps to assist in inserting the esophagus. However, it is often difficult to succeed due to laryngeal edema, obstruction of the endotracheal tube, and restricted body position. It also requires the cooperation of multiple people, high medical costs, long operation time, and easy damage to the surrounding mucosa, resulting in low medical efficiency. Utility Model Content
