Description

Stomach tube fixing device

Technical Field

The utility model relates to the field of medical instruments, in particular to a gastric tube fixing device.

Background

Nasogastric tube refers to a catheter inserted into the stomach through the nasal cavity, primarily to deliver food into the stomach of a patient, which may be done for patients who cannot eat, or to expel the stomach contents to relieve intragastric pressure.

The nasogastric tube is noninvasively operated, so that the nasogastric tube is generally fixed by adhesive tape in the aspect of fixation, the stability is relatively poor, and the person to be placed with the nasogastric tube and the family members are usually required to pay high attention. When the patient sits and lies on the bed, the patient needs to avoid pulling to avoid the nasal gastric tube from falling out, and the patient can possibly go into or irritate the trachea to cause choking and choking, and meanwhile, the previous tube placing operation is wasted, and the patient needs to place the tube again. To avoid increased discomfort to the person being cannulated, the nasogastric tube needs to be highly maintained in place during cannulation.

The prior nasogastric tube fixing device has the following problems:

1. The nasogastric tube body is usually fixed on one side face, so that a patient needs to pay attention to turn over at any time, and the effect of the nasogastric tube treatment is prevented from being influenced by the compression of the tube. If the patient is awake, the patient can pay attention to the body position to avoid turning over the compression catheter, however, after the patient sleeps, the body cannot be controlled to naturally turn over, and the nasogastric tube body still has the risk of being compressed.

2. When the lacing is matched with the clamping piece for use, the lacing is fixed on the ear side of a patient, and when the patient turns over or moves, the lacing can be shifted under the conditions of falling off and the like, so that the clamping piece is shifted to affect the fixing position of the nasogastric tube.
