Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a device for fixing double tubes in a nasal cavity. BACKGROUND

[0002] After cardiothoracic surgery, it is a common medical measure to implant a jejunum nutrition tube and a decompression tube from the nasal cavity, and they each bear an important role to promote the recovery of patients. After cardiothoracic surgery, patients may be unable to eat normally due to surgical trauma, anesthesia influence or temporary non-recovery of digestive tract function. At this time, the jejunum nutrition tube, as an important channel for enteral nutrition, can directly deliver nutrients to the jejunum to ensure that the patient obtains sufficient nutritional support and promotes postoperative recovery. This nutritional support method helps to reduce the dependence on intravenous infusion and reduce the risk of related complications, and the decompression tube reduces the pressure in the stomach by the way of negative pressure suction to discharge the gas and liquid in the stomach to the outside of the body, thereby reducing the pressure in the stomach and relieving the discomfort of the patient.

[0003] At present, the jejunum nutrition tube and the decompression tube are directly used together through the nasal cavity of the patient, but at present, when in use, the jejunum nutrition tube and the decompression tube are put into the nasal cavity of the patient together by using a nasal oxygen tube and fixed by using a cloth strip. Although this can maintain the corresponding functions to a certain extent, directly placing the device for breathing on the nasal cavity of the patient by simply using the nasal oxygen tube not only causes messy fixation and is prone to the condition of supporting the tube, but also causes pain and danger to the patient, and it is difficult to adjust the positions of the jejunum nutrition tube and the decompression tube after fixation.

[0004] Therefore, a device for fixing double tubes in a nasal cavity is needed to solve the above technical problems. CONTENT OF THE UTILITY MODEL
