Description

A multifunctional breathing tube without water humidification Technical Field

[0001] The invention belongs to the technical field of ventilators, and in particular relates to a multifunctional breathing tube without water humidification. Background Art

[0002] Generally speaking, a ventilator is a device commonly used in hospitals and homes to stabilize the patient's breathing and treat the patient. The patient will wear an oronasal mask, which is then connected to the oronasal mask through the ventilator's air tube, and oxygen is delivered to the patient through the air tube. Respiratory nebulization therapy is an important means of treating respiratory system diseases. During treatment, the nebulizer disperses water and drugs into tiny droplets suspended in the gas, and enters the respiratory tract and lungs through the patient's breath. The nebulizer is an important component of the ventilator, which can improve the user's comfort. From a long-term perspective, it can play a certain role in moisturizing and protecting the patient's nasal mucosa and upper respiratory tract, avoiding the occurrence of some related phenomena such as dry nose, dry upper respiratory tract, and dry mouth under long-term ventilator treatment.

[0003] However, existing medical nebulizers are bulky, making them inconvenient to use and carry. The long atomization air path also makes it easy for the atomized drug solution to condense within the spray tube, affecting drug utilization and atomization effectiveness. Traditional humidifiers, typically designed for use with ventilators, are bulky and require water for humidification. When used at night, the main unit is prone to backflow and dry burning, potentially causing fires and other safety hazards. Summary of the Invention

[0004] The present invention provides a multifunctional breathing tube with waterless humidification, which improves the humidification mode and adds atomization and expectoration functions, thereby overcoming the problem of low hose space utilization in the prior art.

[0005] To solve the above problems, the present invention provides the following technical solutions:

[0006] An embodiment of the present invention provides a multifunctional breathing tube with waterless humidification, comprising a breathing mask (1), the breathing mask (1) being connected to a sputum remover (2), the sputum remover (2) being connected to a waterless humidification atomizer (3), the waterless humidification atomizer (3) being connected to a dosing chamber (4), the dosing chamber (4) being connected to a breathing hose (5), the breathing hose (5) being connected to a gas source device, and the gas output by the gas source device being oxygen.

[0007] According to an optional embodiment of the present invention, the expectorant (2) has an inner cavity structure (203) and an outer cavity structure (204); the inner cavity structure (203) of the expectorant (2) is in communication with the breathing mask (1); the outer cavity structure (204) of the expectorant (2) is in communication with the waterless humidifying atomizer (3); the outer cavity structure (204) of the expectorant (2) is in communication with the respiratory port at the end of the inner cavity structure (202) of the expectorant (2); the expectorant (2) faces one side of the breathing mask (1). A one-way valve (201) is provided on the end surface, and a pendulum ball (202) is provided in the inner cavity structure (202) of the expectorant (2). When the patient exhales, the gas pushes the pendulum ball (202) to deflect and swing, generating 0-30HZ vibration, which resonates with the sputum in the human body, loosens the sputum, and facilitates expectoration; when the patient exhales, the respiratory cavity is positively pressurized, and the sputum is pressed out from the bottom of the expectorant (2). When the patient lies down, the pendulum ball (202) tilts due to gravity, and the end respiratory port of the inner cavity structure of the expectorant (2) opens.

[0008] According to an optional embodiment of the present invention, the waterless humidifying atomizer (3) comprises a micro-conical plate (304), a piezoelectric sheet (301) connected to the micro-conical plate (304), a battery compartment (302) connected to the piezoelectric sheet (301), and metal substrates (303) located on both sides of the battery compartment (302); the waterless humidifying atomizer (3) has a middle air inlet channel (306) and an edge air inlet channel (305) arranged around the middle air inlet channel (306); the middle air inlet channel (306) and the edge air inlet channel (305) of the waterless humidifying atomizer (3) are both connected to the outer cavity structure (204) of the sputum remover (2).

(2) The present invention makes the breathing gas more humid through the microporous piezoelectric ceramic sheet, protects the patient's respiratory tract, alleviates the pain of some patients with respiratory diseases, and brings a comfortable experience to the patients. (3) The present invention utilizes human breathing to design a detachable drug storage chamber.

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0024] In view of the problems in the prior art where the humidifier is designed on the ventilator, which is large in size and requires water for humidification, and is prone to backflow and dry burning of the host when used at night, which can easily cause safety accidents such as fire, the present invention provides a multifunctional breathing tube with waterless humidification, which can solve the above technical problems.

[0025] As shown in Figures 1, 2, 8, 9 and 10, a multifunctional breathing tube with waterless humidification includes a breathing mask 1, which is connected to an expectorant 2, which is connected to an waterless humidification nebulizer 3, which is connected to a dosing chamber 4. The dosing chamber 4 is used to place atomized medicine, and other medicines can also be placed therein. The dosing chamber 4 is connected to a breathing hose 5, which is connected to an air source device. The gas output by the air source device is oxygen. Compared with the prior art, the present invention connects the expectorant 2, the waterless humidification nebulizer 3 and the dosing chamber 4 to the pipeline, effectively reducing the volume of the ventilator, increasing the function of the nebulizer, and changing the volume of the atomized medicine capsule 403 of the dosing chamber 4 by breathing to deliver liquid, making it more convenient to carry. The expectorant 2 is connected to the waterless humidification nebulizer 3, resonates with the sputum during deep exhalation, and assists in expelling the sputum from the body.

[0026] As shown in Figures 3 and 4, the expectorant 2 has an inner cavity structure 203 and an outer cavity structure 204. The inner cavity structure 203 of the expectorant 2 is connected to the respiratory mask 1, and the outer cavity structure 204 of the expectorant 2 is connected to the waterless humidifying nebulizer 3. The outer cavity structure 204 of the expectorant 2 is connected to the end breathing port of the inner cavity structure 202 of the expectorant 2. A one-way valve 201 is provided on the end surface of the expectorant 2 facing the respiratory mask 1, and a pendulum ball 202 is provided in the inner cavity structure 202 of the expectorant 2. When the patient exhales, the gas pushes the pendulum ball 202 to deflect and swing, generating 0-30Hz vibration, which resonates with the sputum in the human body, loosening the sputum and facilitating expectoration. When the patient exhales, the respiratory cavity is positively pressurized, forcing the sputum out from the bottom of the expectorant 2. When the patient lies down, the pendulum ball tilts due to gravity, and the end breathing port of the inner cavity structure of the expectorant 2 opens.

[0027] As shown in Figures 5 and 6, the waterless humidifying atomizer 3 includes a micro-conical plate 304, a piezoelectric plate 301 connected to the micro-conical plate 304, a battery compartment 302 connected to the piezoelectric plate 301, and metal substrates 303 located on either side of the battery compartment 302. The waterless humidifying atomizer 3 has a central air inlet channel 306 and edge air inlet channels 305 surrounding the central air inlet channel 306 (see Figure 9). Both the central air inlet channel 306 and the edge air inlet channels 305 of the waterless humidifying atomizer 3 are connected to the outer cavity structure 204 of the expectorant 2. The piezoelectric plate 301 is a microporous piezoelectric ceramic plate.

[0028] As shown in FIG7 , the dosing chamber 4 includes a dosing body, in which an atomized medicine capsule 403 is provided. The side wall of the atomized medicine capsule 403 is a rubber wall 404 , and the air outlet wall of the atomized medicine capsule 403 is a polymer wall 402 , which is connected to a water absorbent sheet 401 .

[0029] The dosing chamber 4 also includes a main air inlet channel 405 located outside the nebulizer capsule 403. One end of the main air inlet channel 405 is connected to the breathing hose 5, and the other end of the main air inlet channel 405 is connected to the edge air inlet channel 305 of the waterless humidification nebulizer 3. The gas channel of the air outlet wall of the nebulizer capsule 403 is connected to the middle air inlet channel 306 of the waterless humidification nebulizer 3.

[0030] Figure 8 is a schematic diagram of normal airflow propagation through a multifunctional, waterless humidification breathing tube provided by an embodiment of the present application. Oxygen is output from the air source device, passes through the breathing hose 5, and then through the outer cavity 405 of the dosing chamber 4. It then passes through the air inlet channels 305 on both sides of the waterless humidification atomizer 3, and then through the outer cavity structure 204 of the expectorant 2, through the inner cavity structure of the expectorant 2, through the breathing mask 1, and into the patient's mouth. The atomized medication capsule 403 in the dosing chamber 4 is deployed toward the expectorant 2 under the influence of the airflow.

[0031] In this embodiment, the patient remains seated when expectoration is required, with the tube in a vertical orientation. During inhalation, the body experiences negative pressure, and gas is drawn in through a one-way check valve. During exhalation, the gas pushes the pendulum to deflect and oscillate, generating a 0-30 Hz vibration that resonates with the sputum in the body, loosening it and facilitating expectoration. During exhalation, the respiratory chamber experiences positive pressure, forcing the sputum out from the bottom. When the patient lies down, the pendulum ball tilts due to gravity, opening the respiratory port.

[0032] Figure 9 is a schematic diagram of the inhalation airflow propagation of a multifunctional breathing tube with waterless humidification provided by an embodiment of the present application. During inhalation, the atomized drug capsule 403 in the drug dosing chamber 4 expands toward the breathing tube 5 under the influence of the airflow. The piezoelectric plate 301 atomizes the absorbed water vapor, humidifying and heating the respirator gas during inhalation. The gas flowing into the drug dosing chamber 4 pipeline from the fan is in the same direction as the inhaled gas from the human body. The gas flowing through the outside of the drug dosing chamber 4 has a faster flow rate. According to Bernoulli's principle, the pressure in the pipeline is low at this time, and the drug dosing chamber 4 expands outward. The liquid inside the expanded drug dosing chamber is squeezed out and transferred to the piezoelectric plate for atomization through the capillary action of the water-absorbing material. By combining the polymer material with the rubber and plastic material, the drug will flow out of the drug dosing chamber during expansion.

[0033] Figure 10 is a schematic diagram of the exhaled airflow propagation of a multifunctional breathing tube with waterless humidification provided in an embodiment of the present application. During exhalation, the exhaled gas passes through the breathing mask 1, flows to the inner cavity structure 203 of the expectorant 2, flows to the outer cavity structure 204 of the expectorant 2, passes through the outer cavity 405 of the dosing chamber 4, and passes through the breathing hose 5. Under the action of the exhaled gas, the atomized drug capsule 403 of the dosing chamber 4 unfolds toward the breathing hose 5. The porous structure of the exhaled gas captures water vapor and heat. At this time, the fan pushes the gas inflow in the direction opposite to the direction of the human body's exhaled gas, the flow rate is low, and the rubber-plastic dosing chamber remains unchanged.

[0034] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
