It can be used to treat respiratory diseases such as bronchitis and asthma. However, the existing atomizer masks have the following shortcomings in actual use: For patients who cannot eat orally, the hospital will insert a nasogastric tube and fix the external tube of the tube with tape. The nasogastric tube can pass through the nasal cavity to deliver nutrients or medicines to the stomach to ensure that the patient can take in enough protein and calories.

[0003] When such patients undergo nebulization therapy or oxygen inhalation, the nasogastric tube will occupy a certain amount of nasal space. When the nebulizer catheter or oxygen inhalation catheter is inserted and used, the nasogastric tube is easily involved, and the actual adhesion of the tape will decrease when it is involved. At the same time, the mask may also compress the nasogastric tube, causing pressure on the patient's skin. Summary of the invention

[0004] The purpose of the present invention is to provide an atomization mask for preventing the adhesive tape of a nasogastric tube from falling off. The mask can avoid the nasogastric tube according to the insertion position of the nasogastric tube to perform normal atomization or oxygen inhalation therapy, and can maintain the normal fixed state of the nasogastric tube without affecting the use of the nasogastric tube.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: An atomizing mask for preventing adhesive tape of a nasogastric tube from falling off comprises a mask body, a nasal tube plug, a blocking head, a catheter and a fixing belt, wherein the fixing belt is connected to the mask body and can be wrapped around the patient's head for fixing, the mask body can cover and fit the position below the patient's face corresponding to the nose, the nasal tube plug and the blocking head can be detachably connected to the position of the mask body close to the nose, the end of the nasal tube plug away from the mask body is an expansion part of a flexible material, and the expansion part is connected to a positioning piece, the mask body is provided with a positioning groove adapted to the positioning piece, the inner wall of the positioning groove is provided with an extrusion layer, the catheter is connected to the bottom of the mask body, and the nasal tube plug is communicated with the catheter, and the nasal tube plug can be inserted into the nostrils to deliver medicine or oxygen into the body.

[0006] Compared with the prior art, the atomizing mask for preventing the adhesive tape of the nasogastric tube from falling off using the above technical solution has the following beneficial effects: The atomizing mask for preventing the adhesive tape of a nasogastric tube from falling off of the present invention utilizes a mask body of a specific shape, and a nasal tube plug and a blocking head that can be adjusted and disassembled at will. When the mask body is worn below the nose, it can avoid being pulled or hindered in the use state of the nasogastric tube and the fixing state of the adhesive tape, while ensuring that the patient's nutritional supply and atomization treatment can be maintained normally.

[0007] Through the coordinated connection between the positioning piece, the positioning groove and the extrusion layer, as well as the deformability of the expansion part and the pulling effect of the positioning piece on the expansion part, the expansion part (i.e., the upper end of the nasal tube plug) is inserted and automatically expands to fit the inner wall of the nostril, thereby achieving full adaptation of the nasal tube plug to the nostril, meeting the needs of the mask body with a special structure to conduct oxygen and drugs to the human body, and achieving the sealing requirements of the nostril in the atomization or oxygen inhalation state.
