Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to an endotracheal tube fixator. Background Art

[0002] The endotracheal tube inserted into the patient's trachea through the oral cavity or nasal cavity plays an important role in the rescue of critically ill patients. It is the most commonly used medical device in clinical first aid resuscitation, rescue of respiratory muscle paralysis, surgical anesthesia, and opening the airway. The safe fixation of the endotracheal tube during use is an important guarantee for the success of intubation.

[0003] The traditional method of fixing the endotracheal tube has always been to first fix the bite block and the endotracheal tube with adhesive tape, and then directly paste the adhesive tape on both cheeks of the patient. Usually, the adhesive tape is fixed on the cheek and nasal wing parts, which is easily affected by the sweat glands and oily secretions of the skin, making the adhesive tape not firmly adhered to the skin. After the endotracheal tube is fixed, there is still a large degree of mobility. Especially when the patient is restless or changes body position, it is more likely to occur phenomena such as catheter displacement, inconvenient tube clamping, inability to quickly aspirate sputum, and tube extubation, which endanger the patient's life safety. In addition, when using adhesive tape for fixation, there may also be a phenomenon of excessive traction, which easily causes discomfort to the patient and looks unsightly; the traction of the adhesive tape on the cheek part aggravates the tension and discomfort of the facial muscles, stimulates the skin to cause inflammation or epidermal ulceration, leading to secondary infection, causing additional pain to the patient, and the fixation of the adhesive tape requires the cooperation of two people to complete, and the operation is complicated.

[0004] To solve the above problems, an endotracheal tube fixator is proposed in the present application. Summary of the Invention

[0005] In view of the problems in the related art, the present invention provides an endotracheal tube fixator, which can conveniently and firmly fix the endotracheal tube in an appropriate position, is convenient for nursing and operation, can further reduce complications, and can also improve the comfort of the patient.

[0006] For this purpose, the specific technical solution adopted by the present invention is as follows:

[0007] An endotracheal tube fixator includes a fixator main body. At the upper left and right ends of the upper section of the fixator main body, upper elongated holes are respectively installed. One end of an upper cord is respectively passed through the two upper elongated holes. Upper hook surfaces are installed at both ends of the upper cord. At the lower left and right ends of the lower section of the fixator main body, lower elongated holes are respectively installed. One end of a lower cord is respectively passed through the two lower elongated holes. Lower hook surfaces are installed at both ends of the lower cord.
