Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to a double-catheter fixer for a nasointestinal tube. Background Art

[0002] Nasogastric and nasojejunal tubes are commonly used in clinical practice. A nasogastric tube is inserted for gastrointestinal decompression, while a nasojejunal tube is inserted for nasogastric feeding of nutritional fluids. During treatment, both tubes are inserted through the patient's nostrils, typically into the same nostril or into each nostril.

[0003] After the existing nasogastric tube and nasojejunal tube are inserted into the patient's nostrils, the two tubes are fixed to the nose at the same time with medical tape. Using medical tape to fix the two tubes to the nose may cause compression of the skin, resulting in pressure damage, causing conflicts between doctors and patients, and also causing local pain and discomfort. Especially for people with sensitive skin or allergic constitution, this irritation may be more obvious, greatly increasing the risk of accidental extubation of patients. Utility Model Content

[0019] In the above implementation process, by arranging the first fixed tube and the second fixed tube to extend into the nostrils, stability can be maintained and the patient can be prevented from removing the tube at will.

[0020] In a specific embodiment, a supporting filling block is provided between the adhesive tape and the first fixing tube.

[0021] In the above implementation process, the support filling block is provided to support the connection stability of the adhesive tape and the first fixing tube.

[0022] Beneficial effect: The present application provides a double-catheter fixer for nasointestinal tubes. By setting an adhesive tape and an ear-hanging tape, it can be pasted first and then hung to prevent patients from unconsciously pulling out the tube due to discomfort caused by intubation. By setting a first fixing tube, a second fixing tube, a fixing piece and a pressure plate, the first fixing tube and the second fixing tube are first fixed on the adhesive tape, and then the nasointestinal tube passing through the two fixing tubes is fixed using the fixing piece and the pressure plate, thereby greatly reducing the pressure on the patient, alleviating the discomfort caused by the pressure, and reducing the risk of accidental extubation of the patient.
