Technical Field
The invention belongs to the technical field of medical appliances, and particularly relates to a quick tracheal cannula picking and fixing device.
Background
At present, the tracheal cannula is fixed after the operation of a patient with clinical tracheotomy mainly in the following modes: (1) The tracheal cannula is fixed on the neck by using cotton ropes, cotton strips or gauze and knotting the two ends of the cotton ropes, the cotton strips or the gauze in the tracheal cannula fixing holes. (2) adhesive plaster is used for adhering to the face, namely, adhesive plaster fixation method; (3) fixing by adopting an auxiliary fixing device. The three fixing methods all have certain problems, and in the first method, the knotted cotton rope, cotton strip or gauze has larger volume, and the too thin cotton rope, cotton strip or gauze can cause uncomfortable feeling to the patient because the cotton rope, cotton strip or gauze presses the neck of the patient more greatly; the knotting is troublesome, and the patient is easy to touch the neck of the patient, thereby causing adverse effects on nursing staff and patients; meanwhile, in the postoperative care process, the patient is easy to be polluted by blood, sputum or other seepage liquid to become stiff, and secondary injury is caused to the neck of the patient. The second method is prone to damage to the patient's skin, especially in elderly patients or patients with facial lesions and facial oedema; the fixed effect is limited, needs two people to cooperate when nursing just can go on moreover, and one person holds up the pipe, and one person operates, extravagant manpower, especially paste the tracheal cannula repeatedly and have partial glue to remain, and some cavity secretion is detained above that easily, forms bacterial culture medium, causes the patient to have the danger of infection. In the third method, the existing auxiliary fixing device is inconvenient to operate or cannot adapt to the necks of different patients, once the auxiliary fixing device is fixed, the auxiliary fixing device cannot be detached and can only be taken down after being cut off, so that waste is caused. At present, an tracheal cannula fixing device which is simple to operate, convenient to replace, comfortable to use for patients and good in fixing effect does not exist.
