Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a cutting structure for nasogastric tube adhesive tape. Background Technology

[0002] Nasogastric tube placement is a common clinical nursing procedure. It involves inserting a nasogastric tube through the nostril, through the pharynx and esophagus, to the stomach. It can be used to aspirate gastric juice or inject food into the stomach to provide nutrition to the patient. After confirming that the nasogastric tube has been inserted into the patient's body to the appropriate position, medical staff must properly secure the part of the nasogastric tube outside the body to prevent it from kinking or dislodging. If the nasogastric tube is not properly secured, it can easily lead to serious consequences such as unplanned extubation, aspiration, or even suffocation.

[0003] Nasogastric tube patches are stickers used to secure the feeding tube to a patient's nose, facilitating facial cleaning and improving patient comfort during nasogastric feeding. Because nasogastric tube patches come in various shapes to fit the patient's nose, related technologies typically use medical nasogastric tube tape for manufacturing. This requires medical staff to manually cut the tape, a time-consuming, labor-intensive, and inefficient process. Therefore, this paper proposes a new nasogastric tube tape cutting structure to overcome these technical shortcomings. Utility Model Content
