Problems solved by technology

[0004] Some existing artificial noses mainly install heating sheets and water-absorbing membranes on the cover body to preheat and humidify to improve the patient's comfort experience, but it will inevitably lead to complex structures. It also needs to be replaced, otherwise it will cause secondary pollution and further increase the cost of use and maintenance
In addition, heating and humidification cannot achieve physiological adjustment, and its functionality is much more defective than that of the human nasal cavity.

Embodiment 1

[0027] A bionic artificial nose with anti-fog function, such as figure 1 As shown, it includes a mask body 1 covering the neck tracheotomy or tracheal intubation. The rubber tube 2 connected to the inside of the mask body 1 is connected to the mask body 1. The other end of the rubber tube 2 is connected to a mask 3. 3. Both ends are provided with hanging ears 4 for hanging on the ears. The mask 3 is a strip structure that covers the mouth or completely covers the mouth and nose. The thickness direction of the mask 3 includes a non-woven fabric layer, a PM2.5 filter layer, and a non-woven fabric layer connected in sequence, and the PM2.5 filter layer is preferred. Made of meltblown polypropylene material. In the present invention, the neck tracheotomy (or endotracheal intubation) is covered by the mask body 1, and when the mask 3 covers the patient's mouth, as Figure 4 As shown, the upper entrance is the nasal cavity, and the lower entrance is the mouth cavity. A is the seve...

Embodiment 2

[0032] At the same time, in order to make the cover body 1 firmly fixed on the patient's neck, the present embodiment is provided with a rubber elastic band 7 on the cover body 1, such as figure 2 As shown, the width of the elastic band 7 is 30mm, and a wider elastic band reduces the patient's feeling of constriction, and also promotes the stability of the position of the mask body. A plurality of air holes 8 are evenly distributed along the length direction of the elastic band 7 on the elastic band 7 . Other parts are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0034] In order to realize the length and tightness adjustment of elastic band 7, elastic band 7 can also be made into two parts on the basis of embodiment two, as image 3 As shown, the left elastic band and the right elastic band are respectively, and one end of the left elastic band and the right elastic band is respectively fixed with the cover body 1, and one end of the left elastic band is fixed with a connecting button, and a plurality of ventilation holes 8 are set along the length direction of the elastic band on the right elastic band, and then select Vent holes in suitable positions, and finally put the connecting buttons into the vent holes 8 to realize the matching connection.

Abstract

The invention discloses a bionic artificial nose with anti-fog and haze function, which belongs to the field of medical equipment, and comprises a cover body covering the neck tracheotomy or tracheal intubation. Connected rubber tubes, the other end of the rubber tube is connected to a mask, the two ends of the mask are provided with hanging ears hanging on the ears, the lower end of the side wall of the cover body is provided with a groove, and the groove is embedded with a Silicone ring at the bottom of the body. The present invention realizes heating and humidification by means of the patient's own mouth and nose, and has a simpler structure and is convenient for maintenance; the already disused nose can redisplay the physiological function, which is closer to the physiological function, and can maintain the physiological adjustment of the temperature and humidity of the body while taking into account Anti-smog mask function for special patients.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an artificial nose for assisting breathing, which is suitable for assisting breathing of patients with total laryngectomy. Background technique [0002] In patients with total laryngectomy, the communication between the trachea and the nasal cavity is lost and the function of the nasal cavity is lost. They can only breathe through the neck stoma or neck tracheal tube, so the external air directly enters the neck trachea without heating, humidifying, and filtering the nasal cavity. Dusty process. Many of these patients cannot adapt to changes in temperature, severely restricting their outdoor activities, and even can only stay indoors in winter. In addition, due to the smog problem in recent years, there is no special mask for patients with total laryngectomy. This product takes this function into consideration. [0003] Artificial nose is also called biological filter, heat-moist...
