Problems solved by technology

[0002] At present, the airway humidification of patients with tracheotomy is usually carried out in two ways: continuous or intermittent intratracheal drip and atomized inhalation. Risk of infection and nosocomial cross-infection; ②Do not heat inhaled gas or instilled medicinal solution, cold humidified liquid or gas enters the lower respiratory tract, which can easily cause irritating cough, shortness of breath, or even hypoxia; ③Cold humidified Humidification fluid or gas weakens the movement of respiratory cilia, making it difficult to discharge secretions in the trachea, causing secretions to accumulate and affecting normal respiratory function; ④The catheter used for humidification fluid is easy to move and fall off, increasing pollution; especially when turning over or coughing It is easy to prolapse, which affects the humidification effect and increases pollution; ⑤It can only be humidified at the same position, but other positions in the tracheal tube may still form sputum scab or be blocked by sticky phlegm; ⑥It may cause insufficient or excessive humidification, and the patient Frequent coughing and excessive sputum increase the frequency of sputum suction, which can easily damage the airway mucosa and increase lung infection; ⑦ restrict the patient's activities, for patients with long-term tracheotomy or tracheostomy who can move freely, such as those who have undergone throat surgery , especially inconvenient

Embodiment 1

[0034] Such as figure 1 , figure 2 , image 3 with Figure 4 As shown, the artificial nose assembly of this embodiment includes an artificial nose 1 , an elastic connecting tube 2 is provided at the bottom of the artificial nose 1 , and the elastic connecting tube 2 is embedded in a hollow base 4 provided with an applicator 3 at the bottom.

[0035] The outer diameter of the elastic connecting pipe 2 is equal to the inner diameter of the hollow base 4 .

[0036] The applicator 3 is a composite film applicator 3 made of carapace, soft-shelled turtle whole blood, polyhexamethyleneguanidine, natural rubber latex, and glycerin in proportion. The applicator 3 can be adhered to the corresponding sleeve or directly attached to the skin. It has good viscosity and will not cause redness, swelling, allergies and other discomforts of the skin.

[0037] The elastic connecting pipe 2 is made of silica gel or plastic material.

[0038] The total axial length of the artificial nose 1 a...

Embodiment 2

[0041] Such as Figure 5 with Image 6 As shown, the artificial nose assembly of this embodiment includes an artificial nose 11, and an elastic connecting pipe 12 is provided at the bottom of the artificial nose 11. The elastic connecting pipe 12 is arc-shaped, and the arc of the elastic connecting pipe 12 corresponds to The radian of the body of the full laryngeal endotracheal tube 13 is suitable.

[0042] The outer diameter of the elastic connecting tube 12 is equal to the inner diameter of the body of the corresponding full-laryngotracheal tube 13 .

[0043] The elastic connecting tube 12 is made of silica gel or plastic material.

[0044] The artificial nose assembly is an airway humidification device used during a total laryngectomy patient wearing a tube. The elastic connecting tube 12 of the artificial nose assembly can be embedded in the cylinder body of the full-laryngeal trachea tube 13 to seal the open airway and play the role of airway humidification.

Embodiment 3

[0046] Such as Figure 7 , Figure 8 with Figure 9 As shown, the artificial nose assembly of the present embodiment includes an artificial nose 21, and the bottom of the artificial nose 21 is provided with an elastic connecting tube 22, and the inner diameter of the elastic connecting tube 22 is equal to that of the inner sleeve tube of the tracheotomy sleeve 23. The outer diameter of the inner connection segment.

[0047] The axial length of the elastic connecting pipe 22 is 7-8 mm.

[0048] The elastic connecting tube 22 is made of silica gel or plastic material.

[0049] The outer diameter of the artificial nose 21 is 35mm.

[0050] The artificial nose assembly is an airway humidification device used after partial laryngectomy. The elastic connecting tube 22 of the artificial nose assembly can be set on the inner connecting section of the inner sleeve of the tracheotomy sleeve 23 to seal the open airway and play the role of airway humidification.

Abstract

The invention discloses an artificial nose assembly which relates to the technical field of medical instruments. The artificial nose assembly comprises an artificial nose; the bottom of the artificial nose is provided with an elastic connecting pipe; and the elastic connecting pipe is embedded into a hollow base, of which the bottom is provided with an application plaster. The artificial nose assembly has the advantages as follows: 1, warming and humidification are effectively carried out; 2, an open airway is changed into a closed airway, so that pulmonary infection and cross infection are reduced; 3, the movement of a patient is not influenced; and 4, the artificial nose assembly can be replaced at any time after being contaminated.
