Description

A Medical Ultrasonic Atomizing Nozzle Based on Gas Nozzle

technical field

The utility model belongs to the technical field of medical equipment, in particular to a medical ultrasonic atomizing nozzle based on a gas nozzle.

Background technique

The medical ultrasonic atomizing nozzle is one of the accessories of the medical ultrasonic nebulizer. The nozzle is the main part of the connection between the ultrasonic nebulizer and the breathing mask. Since the nebulizer of the ultrasonic nebulizer has no selectivity to the mist particles, the spray after passing the nozzle Most of the drug particles deposited in the mouth, throat and other upper respiratory tracts cannot effectively treat lower respiratory tract diseases; at the same time, the mist particles produced by the nebulizer are large and atomized quickly, causing patients to inhale too much water vapor and humidify the respiratory tract , the dry and thick secretions in the respiratory tract that partially blocked the bronchi absorb water and expand after absorbing water, increasing the resistance of the respiratory tract, which may cause hypoxia, and the ultrasonic nebulizer will cause the liquid to form water droplets and hang on the inner cavity wall, which is harmful to the The effect of lower respiratory diseases is not good, and the demand for drugs is large, resulting in waste. Therefore, it is very necessary to develop a new medical ultrasonic atomizing nozzle to slow down the flow of the spray produced by the atomizer, and to refine the atomized drug particles with large atomized particles.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a medical ultrasonic atomizing nozzle based on a gas nozzle, which is reasonable in structure, easy to use, slows down the spray flow, and refines the spray particles.

The technical scheme of the utility model is: a medical ultrasonic atomizing nozzle based on a gas nozzle, including an outer shell, the outer shell is sleeved on the outlet of the ultrasonic atomizer, and a card slot is arranged inside the outer shell, A speed-reducing net is set in the card slot. After the atomized matter produced by the ultrasonic nebulizer passes through the speed-reducing net, due to the resistance of the speed-reducing net, the speed of the atomized matter will decrease, thereby preventing the patient from inhaling too much water vapor. When the rapid atomized matter impacts the speed-reducing net, the atomized particles will be further refined. There is also a thread inside the outer shell, and a buckle is arranged at the end of the thread, and the buckle is set in the slot of the outer shell The upper end surface of the outer casing is connected with a hollow positioning lock through a thread, and the positioning lock enters the outer casing through a threaded rotation. , the other side of the positioning lock is connected with a gas nozzle, the gas nozzle will increase the pressure of the atomized substance at the outlet, and the atomized particles after refinement will enter the lower respiratory tract more easily after passing through the gas nozzle, which improves and strengthens the Therapeutic effects in lower respiratory diseases.

Further, preferably, the positioning lock can be connected to the gas nozzle through threads.

Further, preferably, the positioning lock is integrated with the gas nozzle.

Further, preferably, the gas nozzle is set as a Rafal nozzle.

The utility model has the beneficial effects of slowing down the flow rate of the spray, preventing patients from inhaling too much water vapor, refining the spray particles again so that the spray particles can directly reach the lower respiratory tract, and improving and enhancing the therapeutic effect on lower respiratory tract diseases.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

The utility model provides a medical ultrasonic atomizing nozzle based on a gas nozzle, its structure is shown in Figure 1, including an outer shell 1, the outer shell 1 is sleeved on the outlet of the ultrasonic atomizer, the outer shell 1 is provided with a card slot 3 inside, and the card slot 3 is provided with a speed-reducing net 4. After the atomized matter generated by the ultrasonic atomizer passes through the speed-reducing net, the speed of the atomized matter will decrease due to the resistance of the speed-reducing net. In order to prevent the patient from inhaling too much water vapor, when the rapid atomized substance hits the speed-reducing net, the atomized particles will be further refined. The outer casing 1 is also provided with a thread 2, and a clamp is provided at the end of the thread 2. Buckle, the buckle shown is arranged on the upper end surface of the card slot 3 of the outer casing, the outer casing 1 is connected with a hollow positioning lock 6 through a thread 2, and the positioning lock 6 enters the outer casing 1 by thread rotation, and the positioning lock 1 There is a buckle protrusion 5 at the end of the thread, and the buckle protrusion 5 enters the buckle to position the speed reduction net 4. The other side of the positioning lock 6 is connected to a gas nozzle 7, which will increase the outlet atomization Pressure, the atomized particles after refinement will enter the lower respiratory tract more easily after passing through the gas nozzle, improving and enhancing the therapeutic effect on lower respiratory tract diseases.

Further, the positioning lock 6 can be connected to the gas nozzle 7 through threads.

Further, the positioning lock 6 is integrated with the gas nozzle 7 .

Further, the gas nozzle 7 is set as a Rafal nozzle.
