Multifunctional medical artificial nose

Abstract

The invention discloses a multifunctional medical artificial nose. The artificial nose includes an outer tube inserted in the trachea of a patient, an inner tube is inserted in the outer tube, the end, stretching out of the outer tube, of the inner tube is connected with a tube connection device, the lower end of the tube connection device is connected with a cylindrical air humidifying and heating device through a catheter, the cylindrical air humidifying and heating device includes a first outer ring and a second outer ring which are in threaded connection, a filter net is arranged in the first outer ring, a separation plate is arranged in the second outer ring, the separation plate divides the inside of the outer ring into a heating layer and a humidifying layer, heating wires are arranged in the heating layer, several air outlets are formed in the separation plate, the side, located on the humidifying layer, of the separation plate extends and is provided with a humidifying tube communicated with the air outlets, the humidifying tube is provided with several humidifying holes in the peripheral direction, and a water-absorbing sponge is embedded in the humidifying layer in the second outer ring. The multifunctional medical artificial nose is compact in structure, can filter, humidify and heat air, improves the user's comfort by imitating the function of the nasal cavity of ahuman body, and has a good preventive effect on some respiratory diseases.

Description

Technical field [0001] The invention relates to an artificial nose, in particular to a multifunctional medical artificial nose. Background technique [0002] An artificial nose is a device made of medical polymer materials. It is used for some patients with nasal defects due to trauma or other diseases. It is often necessary to perform an incision on the patient’s trachea and use a catheter to draw out the breath. However, the existing artificial The nose does not have the function of heating and humidifying the air inhaled into the lungs, and even some artificial noses do not even have the function of filtering. Invisible, the first line of defense of the human respiratory system is lost, which affects the patient's breathing. Comfort, easy to cause cough, on the other hand, easy to cause respiratory diseases, so it is very necessary to invent a multifunctional medical artificial nose with filtering, heating, and humidifying functions. Summary of the invention [0003] The techn...

[0002] The artificial nose is a device made of medical polymer materials. It is used for some patients with nasal defects due to trauma or other lesions. It is often necessary to perform incision surgery on the patient's trachea and use a catheter to draw out breathing. However, the existing artificial nose The nose does not have the function of heating and humidifying the air inhaled into the lungs, and even some artificial noses do not have the function of filtering, which invisibly loses the first line of defense of the human respiratory system, which affects the patient's breathing on the one hand Comfort, it is easy to cause coughing, and on the other hand, it is easy to cause respiratory diseases, so it is very necessary to invent a multifunctional medical artificial nose with filtering, heating and humidifying functions
