An atomizing face mask connector with improved flow rate

Abstract

This utility model proposes a nebulizer mask connector that can improve airflow rate, particularly relating to the field of nebulizer mask connector technology. It includes a first conical tube. When using this nebulizer mask connector, the airflow rate can be adjusted according to the patient's actual needs. This is achieved by rotating a C-shaped buckle using a dial. When rotating the C-shaped buckle, different sized second exhaust ports coincide with the first exhaust port, controlling the amount of airflow overflow. During rotation, a limiting rod, through interference fit, engages with a slot on the outside of a limiting protrusion, thus limiting the C-shaped buckle. When engaged in different slots, the dial aligns with the corresponding position protrusion, making it easier for the user to observe. When engaged in different slots, the first exhaust port aligns with different sized second exhaust ports. When airflow overflow is not desired, simply cover the first exhaust port with the solid part of the C-shaped buckle. Four position protrusions are provided.

[0018] Example

[0019] Please see Figure 1-4 This utility model discloses an atomizing mask connector that can improve flow rate: It includes a first conical tube 1, with a first connecting tube 2 integrally formed at one end of the first conical tube 1. A second connecting tube 3 is fixedly connected to the outer side of the first connecting tube 2. A third connecting tube 4 is integrally formed at the other end of the first conical tube 1. A second conical tube 5 is fixedly connected to the inner cavity of the first connecting tube 2. A conical cavity 6 is provided on the inner side of the first conical tube 1. A connecting groove 7 is opened on the outer side of the third connecting tube 4. A first exhaust port 8 is provided through the outer side of the third connecting tube 4. An adjustment mechanism is provided on the outside of the receiving slot 7. In use, the first connecting pipe 2 is connected to the ventilator tubing, the second connecting pipe 3 is connected to the nebulizer, and the third connecting pipe 4 is connected to the breathing mask or mouthpiece. The second connecting pipe 3 is connected to the first connecting pipe 2, which can mix the ventilator gas with the nebulized medication and deliver it to the patient's breathing through the first conical tube 1 and the third connecting pipe 4. The setting of the second conical tube 5 can realize the Venturi effect and increase the gas flow rate. The setting of the conical cavity 6 can reduce the condensation and backflow of the mist.

[0020] Furthermore, the inner sides of the first connecting pipe 2, the second connecting pipe 3, and the third connecting pipe 4 are all tapered.

[0021] To facilitate adjustment of the mist during breathing, the adjustment mechanism includes a gear position protrusion 9, a limit protrusion 10, a C-shaped buckle 11, a lever 12, a limit rod 13, a second exhaust port 14, a shield 15, and an air outlet 16. The gear position protrusion 9 is integrally formed on the outer side of the third connecting pipe 4. The limit protrusion 10 is integrally formed on the outer side of the connecting groove 7. The C-shaped buckle 11 is snapped onto the outer side of the connecting groove 7. The lever 12 is integrally formed on the outer side of the C-shaped buckle 11. The limit rod 13 is integrally formed on the inner side of the C-shaped buckle 11. The second exhaust port 14 is located on the outer side of the C-shaped buckle 11. The shield 15 is integrally formed on the outer side of the C-shaped buckle 11. An air outlet 16 is located on one side of the shield 15. When using the connector, the adjustment is made according to the patient's actual usage. The flow rate of the mist can be controlled by rotating the C-shaped buckle 11 using the dial 12. When rotating the C-shaped buckle 11, the second exhaust ports 14 of different sizes coincide with the first exhaust port 8, which can control the amount of mist overflow. When rotating the C-shaped buckle 11, the limiting rod 13 will be inserted into the slot on the outside of the limiting protrusion 10 through interference fit, thereby limiting the C-shaped buckle 11. When inserted into the slot at different positions, the dial 12 will coincide with the corresponding gear protrusion 9, making it easier for the user to observe. When inserted into different slots, the first exhaust port 8 coincides with the second exhaust port 14 of different diameters. When it is not necessary to overflow the mist, simply cover the first exhaust port 8 with the solid part of the C-shaped buckle 11. There are four gear protrusions 9.

[0022] Furthermore, the limiting protrusions 10 are evenly distributed on the outer wall of the connecting groove 7, and a slot is provided on the outer side of the limiting protrusions 10.

[0023] Furthermore, there are three second exhaust ports 14, and the three second exhaust ports 14 are of different sizes.

[0024] Furthermore, the outer wall of the limiting rod 13 fits against the inner wall of the slot.

[0025] Working principle: In use, the first connecting tube 2 is connected to the ventilator tubing, the second connecting tube 3 is connected to the nebulizer, and the third connecting tube 4 is connected to the breathing mask or mouthpiece. The second connecting tube 3 is connected to the first connecting tube 2, which allows the ventilator gas to be mixed with the nebulized medication and delivered to the patient's breathing through the first conical tube 1 and the third connecting tube 4. The second conical tube 5 achieves the Venturi effect, increasing the gas flow rate, while the conical cavity 6 reduces fog condensation and backflow. When using the connector, the fog flow rate is adjusted according to the patient's actual needs by simply rotating the C-shaped buckle 11 using the lever 12. When the C-shaped buckle 11 is rotated, the second exhaust port 14 of different sizes coincides with the first exhaust port 8, which can control the amount of fog overflow. When the C-shaped buckle 11 is rotated, the limiting rod 13 will be inserted into the slot on the outside of the limiting protrusion 10 through interference fit, thereby limiting the C-shaped buckle 11. When inserted into the slot at different positions, the lever 12 will coincide with the corresponding gear protrusion 9, making it easier for the user to observe. When inserted into different slots, the first exhaust port 8 coincides with the second exhaust port 14 of different sizes. When fog overflow is not required, the solid part of the C-shaped buckle 11 can be used to cover the first exhaust port 8. There are four gear protrusions 9.
