Problems solved by technology

[0003] 1. The air inhaled by patients with total laryngectomy is relatively dry, resulting in dry airway and mucous membranes in patients with easy bleeding in winter; 2. Harmful substances in the air such as PM2.5 cannot be filtered; 4. The plastic tracheal tube combined with the "artificial nose" can moisten the inhaled gas, but the plastic tracheal tube is easy to block and age, and cannot be disinfected regularly, so it needs to be replaced frequently; the volume of the "artificial nose" Larger, not suitable for long-term placement on the neck

Abstract

The invention discloses a catheter for a tracheostomy opening, comprising a catheter body. The catheter body is sequentially provided with an outer isolation layer, a support layer and an inner isolation layer from the outside to the inside. One end of the outer isolation layer has an outer side wall. There is a fixed plate that expands outward, the other end of the outer isolation layer is bent and contracted toward its axis, one end of the inner isolation layer is provided with a filter layer, and the middle of the inner isolation layer is provided with a humidification layer, so The fixed plate has an annular cavity for storing humidification medium, the fixed plate is provided with a medium inlet and outlet that communicates with the annular cavity, and the annular cavity is provided with a water delivery pipe connected to the humidification layer .

Description

technical field [0001] The invention relates to the field of medical recovery equipment, in particular to a catheter for tracheostomy. Background technique [0002] The main treatment for laryngeal malignancies is surgery, including partial laryngectomy and total laryngectomy. A permanent tracheostomy is formed after total laryngectomy. After the total laryngectomy patients complete all treatments, they need to wear a metal catheter to facilitate sputum suction and avoid narrowing of the stoma. The following problems exist in the prior art: [0003] 1. The air inhaled by patients with total laryngectomy is relatively dry, which makes the airway dry and mucous membrane easy to bleed in winter. 2. It cannot filter harmful substances in the air such as PM2.5. 4. The plastic tracheal tube combined with the "artificial nose" can moisten the inhaled gas, but the plastic tracheal tube is easy to block and age, cannot be disinfected regularly, and needs to be replaced frequently; t...
