specific Embodiment

[0053] see Figure 1-Figure 3 , Figure 6 , Embodiment 1 of an atomizer drug delivery nozzle in the present invention includes a tubular nozzle body 2, one end of the nozzle body 2 is a drug inlet, and the other end is a drug injection port 2.1. The above-mentioned first sensor 3.1 is a first reed switch, and the above-mentioned second sensor 4.1 is a second reed switch. On the tube wall of the nozzle body 2, a one-way opening to the outside of the nozzle is set when the spray port 2.1 is exhaled. Exhalation detection valve 3 and an inhalation detection valve 4 that one-way opens in the nozzle when inhaling to spraying mouth 2.1, exhalation detection valve 3 and inhalation detection valve 4 are one-way valves. A first magnet 3.3 and a second magnet 4.3 are respectively arranged on the door body 3.2 of the exhalation detection valve and the door body 4.2 of the inhalation detection valve, and the pipe wall of the nozzle body 2 close to the first magnet 3.3 is arranged for dete...

Embodiment 2

[0056] see Figure 1-Figure 3 , Figure 6, Embodiment 2 of an atomizer drug delivery nozzle according to the present invention, the structure of the nozzle body 2, the structure and setting position of the exhalation detection valve 3 and the inhalation detection valve 4 in this embodiment are basically the same as those of Embodiment 1, the difference One of the places is: the first reed switch 3.1 is replaced by the first Hall switch, the second reed switch 4.1 is replaced by the second Hall switch, the first Hall switch and the second Hall switch are respectively connected with the atomizer control System connection; the second difference is: the nebulizer control system not only includes the intelligent breathing valve state detection module, but also includes the door opening angle calculation for detecting the exhalation detection valve 3 and the inhalation detection valve body 4 logic module. The atomizer control system judges the opening and closing state or the open...

Embodiment 3

[0057] see Figure 4 , Figure 6 , Embodiment 3 of an atomizer drug delivery nozzle of the present invention includes a nozzle body 2, the nozzle body 2 is tubular, one end of the nozzle body 2 is a drug inlet, and the other end is a drug spray port 2.1. An aerosol medicine bin 6 is provided with a drug inlet and an aerosol medicine bin valve 6.1, the aerosol medicine bin valve 6.1 is connected with the medicine inlet of the nozzle body 2, and the aerosol medicine bin valve 6.1 is a solenoid valve, A drug concentration sensor 6.2 is arranged in the 6, and the drug concentration sensor 6.2 and the aerosol drug storehouse valve 6.1 are respectively connected with the nebulizer control system. The nebulizer control system includes an intelligent breathing valve state detection module, a door opening angle calculation logic module, and a drug storehouse drug concentration detection module. An exhalation detection valve 3 is arranged on the top of the pipe wall of the nozzle body...

Abstract

The invention provides a drug administration nozzle of an atomizer, intelligent self-adjustable drug administration equipment and an application method. The drug administration nozzle is characterized in that: a nozzle body is provided with an exhaling detection valve which is opened toward the outside of the nozzle in one direction and an inhaling detection valve which is opened toward the inside of the nozzle in one direction; door bodies of two valves are provided with a first magnet and a second magnet respectively; a first sensor is arranged on a pipe wall, close to the first magnet, of the nozzle body; a second sensor is arranged on a pipe wall, close to the second magnet, of the nozzle body; the first sensor and the second sensor are connected with an atomizer control system respectively; the atomizer control system comprises an intelligent breathing valve state detection module and is used for controlling a working state of the atomizer according to received valve switching state detection signals sent by the first sensor and the second sensor. The drug administration nozzle can be used for accurately sensing breathing behaviors of a patient in real time and the nozzle of the atomizer can realize an intelligent self-adjustment type and the atomizer is instantly available; meanwhile, a structure is simplified, the manufacturing cost is reduced and power consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and relates to an improvement of nebulizer treatment equipment, in particular to an nebulizer drug delivery nozzle, an intelligent self-adjusting nebulizer drug delivery device and a method of use. Background technique [0002] With the increasing severity of global climate change and air pollution, the incidence of wheezing diseases is increasing year by year, and the incidence frequency of individuals shows an increasing trend. Especially among children aged 3 to 14, the prevalence of asthma is as high as 3%. Asthma not only affects children's physical development, but also is an invisible "killer" that endangers children's lives. The treatment of children's asthma has attracted widespread attention from parents. Viral infection is an important factor in inducing wheezing and acute attack of asthma in children. It is understood that about 20% of infants have wheezing due to viral in...
