Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically, to a device for preventing the dislodgement of medical cannulas. Background Technology
[0002] In the medical field, intubation is a common and crucial procedure widely used in various clinical scenarios, such as emergency care, surgery, intensive care, and long-term treatment. The purpose of intubation is to ensure a patient's airway patency, provide necessary respiratory support, or perform specific therapeutic interventions. However, a major challenge during intubation is ensuring the stability and safety of the tube, preventing accidental dislodgement or displacement, which could lead to respiratory distress, increased risk of infection, or even death. Traditional methods of tube fixation typically rely on tape, bandages, or simple ligation. While these methods can secure the tube to some extent, they have several limitations. First, they are often difficult to adapt to different patient body shapes and head sizes, resulting in poor fixation. Second, prolonged use can lead to pressure sores, allergies, or discomfort. Furthermore, these fixation methods can loosen during routine care, failing to provide consistently stable fixation. Utility Model Content

[0005] A fixing component is disposed on the side of the telescopic belt away from the buffer pad. The fixing component is disposed corresponding to the nasal cavity. The side wall of the fixing component is fixedly connected to the telescopic belt. The fixing component is used to engage with the cannula. The top of the fixing component is provided with multiple recesses.
[0006] A limiting component is provided at the bottom of one end of the limiting component, which is provided with a protrusion that matches the plurality of recesses. The limiting component is engaged with the plurality of recesses on the fixing component through the plurality of protrusions. The other end of the limiting component is bonded to the insertion tube.
[0007] In some embodiments, the axial cross-section of the cushioning pad is rectangular, and the cushioning pad is used to abut against the back of the human head.
[0008] In some embodiments, the hook face is disposed on the inner wall of one end of the telescopic belt, and the mounting end of the hook face is fixedly connected to the inner wall of one end of the telescopic belt. The rough face is disposed on the outer wall of the other end of the telescopic belt, and the mounting end of the rough face is fixedly connected to the outer wall of the other end of the telescopic belt.
[0009] In some embodiments, the fixing component includes:
[0010] A fixing block, both ends of which are fixedly connected to the telescopic belt, and two grooves are provided on the side of the fixing block near the nasal cavity;
[0011] Two anti-slip mats are provided, and the two anti-slip mats are respectively disposed inside the two grooves. The mounting surface of the anti-slip mat matches the shape of the inner wall of the groove, and the mounting surface of the anti-slip mat is fixedly connected to the inner wall of the groove.

[0036] As mentioned in the background section, intubation is a common and crucial medical procedure in the medical field, widely used in various clinical scenarios such as emergency care, surgery, intensive care, and long-term treatment. The purpose of intubation is to ensure a patient's airway patency, provide necessary respiratory support, or perform specific therapeutic interventions. However, a major challenge during intubation is ensuring the stability and safety of the intubation tube, preventing accidental dislodgement or displacement, which could lead to respiratory distress, increased risk of infection, or even death.

Second, prolonged use can lead to pressure sores, allergies, or discomfort for patients. Furthermore, these fixation methods may loosen due to routine care procedures, failing to provide consistently stable fixation.
[0037] To address the aforementioned issues, this application proposes an anti-dislodgement fixation device for medical intubation. The Velcro design on the telescopic strap allows medical staff to fine-tune the device according to the patient's head circumference and intubation position, ensuring a close fit to the patient's head. This allows patients of all ages, including adults, children, and the elderly, to find the most suitable wearing method.

A soft cushioning pad is carefully placed near the back of the head, effectively dispersing the pressure of the intubation on the head and reducing discomfort or pain that may occur during prolonged wear. The telescopic strap is made of a breathable material, keeping the scalp dry even in hot summer weather or during prolonged wear, avoiding skin problems caused by heat.
