Description

Technical Field

[0001] The utility model relates to the technical field of nasal catheters, in particular to a feeding nasal catheter for fiberoptic bronchoscopy of children. Background Art

[0002] Bronchoscopy is a procedure in which a slender bronchoscope is inserted into the patient's lower respiratory tract through the mouth or nose, that is, through the glottis into the trachea, bronchi and beyond, to directly observe lesions in the trachea and bronchi, and perform corresponding examinations and treatments based on the lesions.

[0003] During the existing bronchoscopy, due to the blockage of the trachea, children need to be supplied with oxygen through a nasal cannula. However, the existing nasal cannula is fixed by medical tape. During the bronchoscopy, children struggle greatly. It is difficult to stabilize the nasal cannula by simply fixing it with tape, and it is easy to fall off and cause hypoxia. Therefore, a supply nasal cannula for fiberoptic bronchoscopy in children is proposed to solve the above problem. Utility Model Content

[0004] The utility model provides a feeding nasal catheter for fiberoptic bronchoscopy examination of children, which solves the above technical problems.

[0005] In order to solve the above technical problems, the utility model provides a nasal catheter for fiberoptic bronchoscopy examination in children, including an air supply tube, one end of the air supply tube is connected to a nasal catheter, the surface of the air supply tube is connected to an ear hook, a positioning plate is provided on one side of the ear hook, the air supply tube and the nasal catheter are connected by a medical connector, and the material of the nasal catheter is silicone rubber.

[0006] Preferably, the surface of the nasal catheter is provided with scales and length numbers.

[0007] Preferably, an adhesive sticker is fixed to the back of the positioning plate, and the positioning plate is adhered to the face.

[0008] Preferably, a limiting ring is fixed to one end of the ear hook and the air supply pipe is slidably connected to the limiting ring.

[0009] Preferably, an elastic rope is fixed to one end of the ear hook, and the other end of the elastic rope opposite to the ear hook is connected to a limiting ring.

[0010] Preferably, the length of the nasal catheter is 2 mm.

[0011] Preferably, the length of the nasal catheter is 3 mm.

[0012] Compared with the related art, the nasal cannula for fiberoptic bronchoscopy of children provided by the utility model has the following beneficial effects:

[0013] The utility model fixes the air supply tube by means of a positioning plate and an ear hook, thereby ensuring the stability of the air supply tube. The length of the nasal cannula extending into the nasal cavity can be known through scales on the surface, and the length of the nasal cannula can be adjusted according to the age of the child, thereby ensuring stable oxygen supply without harming the child.

[0017] Embodiment 1, by Figure 1-2 The utility model includes a nasal catheter for fiberoptic bronchoscopy of children, including an air supply tube 3, one end of the air supply tube 3 is connected to a nasal catheter 5, the surface of the air supply tube 3 is connected to an ear hook 2, one side of the ear hook 2 is provided with a positioning plate 1, the air supply tube 3 and the nasal catheter 5 are connected by a medical connector, and the material of the nasal catheter 5 is silicone rubber.

[0018] The surface of the nasal catheter 5 is provided with scales and length numbers.

[0019] An adhesive sticker is fixed to the back of the positioning plate 1, and the positioning plate 1 is adhered to the face.

[0020] A limiting ring is fixed at one end of the ear hook 2 and the air supply pipe 3 is slidably connected to the limiting ring.

[0021] An elastic cord 4 is fixed to one end of the ear hook 2, and the other end of the elastic cord 4 opposite to the ear hook 2 is connected to a limiting ring.

[0022] The length of the nasal catheter 5 is 2 mm.

[0023] The nasal catheter 5 is inserted into the nasal cavity of a child under one year old, and the insertion length is determined according to the scale on the surface of the nasal catheter 5. After the insertion is completed, the air supply tube 3 is fixed to the child's face through the positioning plate 1, and the ear hook 2 is put on the surface of the child's ear. The elastic rope 4 limits the deformation of the ear hook 2, so that the ear hook 2 is hung more stably.

[0024] Embodiment 2, by Figure 1-2 The utility model includes a nasal catheter for fiberoptic bronchoscopy of children, including an air supply tube 3, one end of the air supply tube 3 is connected to a nasal catheter 5, the surface of the air supply tube 3 is connected to an ear hook 2, one side of the ear hook 2 is provided with a positioning plate 1, the air supply tube 3 and the nasal catheter 5 are connected by a medical connector, and the material of the nasal catheter 5 is silicone rubber.

[0025] The length of the nasal catheter 5 is 3 mm.

[0026] The nasal cannula 5 is inserted into the nasal cavity of a child over one year old. The longer nasal cannula 5 can be inserted in place, thereby ensuring a stable oxygen supply to the child over one year old.
