Embodiment Construction

[0012] like figure 1 As shown, the children's nasotracheal catheter anti-blocking device includes a plugging head 1, a connecting guide core 2, and a pull ring 3. The plugging head 1 and the pulling ring 3 are respectively connected to two ends of the connecting guide core 2. It is in the shape of a bullet head, and the diameter at the widest part is the same as the inner diameter of the endotracheal tube end, which can form a gap fit with the inner cavity of the endotracheal tube end. The connecting guide core 2 is made of aluminum rod, and the outer surface is wrapped with PVC film, which can produce deformation. The outer diameter of the core 2 is smaller than the inner diameter of the endotracheal tube, and the length of the connecting guide core 2 is greater than the length of the lumen of the endotracheal tube.

[0013] During specific clinical operations, before intubation, insert the plugging head 1 from the joint at the end of the endotracheal tube until the plugging ...

Abstract

A pediatric nasal tracheal catheter anti-blocking device comprises a plugging head, a connecting guide core and a pull ring. The plugging head and the pull ring are connected to two ends of the connecting guide core, the plugging head is in the shape of a bullet head, the diameter of the widest position of the plugging head is as same as the inner diameter of the head end of a tracheal catheter, the plugging head can be in clearance fit with an inner cavity of the head end of the tracheal catheter, the connecting guide core comprises an aluminum rod, the outer surface of the connecting guide core is wrapped with a pvc (polyvinyl chloride) film, deformation can be generated, the outer diameter of the connecting guide core is smaller than the inner diameter of the tracheal catheter, and the length of the connecting guide core is larger than that of a cavity of the tracheal catheter. Compared with the prior art, the pediatric nasal tracheal catheter anti-blocking device has the advantages that the device is simple in structure, convenient to manufacture and safe and convenient to use, the problem of catheter obstruction is solved, and lung infection rate is reduced.

Description

technical field [0001] The invention relates to the field of medical treatment, in particular to an anti-blocking device for children's nasal cavity and trachea catheter used in clinical anesthesia. Background technique [0002] During the tracheal intubation process of the existing children's nasal cavity tracheal tube, it is easy to bring the smeg and secretions in the nasal cavity into the tracheal tube. It can cause bronchial blockage and increase the chance of lung infections. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problem and design a kind of infantile nasotracheal catheter anti-blocking device with simple structure, safe and convenient use, which can solve catheter blockage and reduce pulmonary infection rate. [0004] The technical measures taken by the present invention to solve its technical problems are: [0005] The children's nasotracheal tube anti-blocking device includes a blocking head, a con...
