Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a stomach tube fixer capable of preventing accidental removal. Background Art

[0002] Gastric tube is a commonly used medical device, mainly used to examine gastric diseases, treat gastric diseases and provide nutrition for patients who cannot eat normally. However, during use, the gastric tube may be accidentally pulled out due to various reasons, such as the patient's unconscious movements or the carelessness of the nursing staff when taking care of the patient, which may lead to the accidental removal of the gastric tube, which will not only cause physical pain to the patient, but also may affect the effect of treatment.

[0003] In order to solve this problem, the position is usually fixed by adhesive tape in clinical practice. Since the oil secretion on the face can easily cause the adhesive tape to fall off, the gastric tube is easily removed accidentally. In order to overcome the above problems, after searching, the "gastric tube fixer" disclosed in the existing application number "202320366771.7" "can set the gastric tube on the elastic belt through the cooperation of the gastric tube limiting belt and the positioning sheet. The elastic belt can adjust the diameter with the cooperation of the head pad, the adhesive hook surface and the adhesive velvet surface, so as to facilitate the fixing of the position, thereby fixing the position of the gastric tube. At the same time, the position of the gastric tube can be conveniently adjusted with the cooperation of the movable block. The stability of the gastric tube position fixation can be ensured through the cooperation of the overall structure." It does have better practicality and can effectively fix the gastric tube. However, this type of gastric tube fixer still has certain shortcomings in actual use:

[0004] The adhesive hook surface is bonded to the adhesive velvet surface to combine the elastic band with the head pad and fix the position of the elastic band. However, in actual use, the adhesive hook surface, the adhesive velvet surface and the excessive protrusion of the head pad may cause certain discomfort to the patient's head. In addition, the elastic band is directly tightened on the patient's lips or nose bridge, and the small fixing block directly acts on the lips or nose bridge, which may also cause certain discomfort to the patient. Based on this, it is highly practical to provide a fixing device that is comfortable to wear, can effectively fix the gastric tube, and prevent the gastric tube from being accidentally removed.
