Background

The bronchial excitation test is a method for inducing airway smooth muscle contraction through artificial stimulation such as physical, chemical and biological stimulation, and then judging whether the bronchus is constricted or not and the degree of the constriction of the bronchus by means of the change of lung function indexes, and is the most common and accurate clinical examination for determining airway hyperresponsiveness.

The stimulation of the airway by external factors can cause spasm and contraction reaction; in contrast, spastically constricted airways are relieved naturally or following broncho-diastolic drug therapy, a phenomenon known as airway reversibility. Airway reactivity and airway reversibility are 2 important pathophysiological features of airway function changes. The principle of the bronchial tube excitation test is the same as that of the bronchial tube excitation test, and the change of the airway function is reflected by the pulmonary function index in clinical practice because the direct measurement of the airway tube diameter is difficult. A method of observing the relaxing response of an obstructed airway by the administration of a treatment with a bronchorelaxing drug is known as the bronchorelaxing test.

Above two kinds of experiments can use multiple experimental liquid medicine clinically, and medical personnel can frequently change the liquid medicine of different kinds or concentration when experimental at every turn, and not only troublesome to it is very easy to take wrong medicine, brings unnecessary puzzlement for clinical treatment.

The plurality of liquid medicine containers 40 are all connected with the atomization module 30, and the atomization module 30 is electrically connected with the main control module 20. The main control module 20 is configured to control the atomizing module 30 to atomize the liquid medicine in the specific liquid medicine container 40, so that the atomized liquid medicine enters the breathing tube 10.

Specifically, one end of the breathing pipeline 10 is provided with a mouthpiece 11, and the other end is communicated with air supply equipment such as external air or a breathing machine. The automatic drug-changing aerosolization device 100 further includes a mouthpiece assembly 50, the mouthpiece assembly 50 connecting the medical fluid container 40 and the breathing conduit 10. In this embodiment, four medical fluid containers 40 are arranged in a line, and all of the four medical fluid containers 40 are communicated with the breathing tube 10 through the interface assembly 50. In other embodiments, the interface assembly 50 may be used to switch different medical fluid containers 40 to communicate with the breathing conduit 10, such that the medical fluid container 40 containing the medical fluid required for aerosolization communicates with the breathing conduit 10, and the temporarily unused medical fluid container 40 does not communicate with the breathing conduit 10. In addition, the liquid medicine container 40 may be provided with a sealing structure (not shown) at the opening, the sealing structure may prevent the liquid medicine in the liquid medicine container 40 that is temporarily unused from evaporating to the outside, or prevent the liquid medicine of the liquid medicine container 40 communicated with the breathing conduit 10 from evaporating to the inside of the breathing conduit 10 during a non-atomization time, and meanwhile, the sealing structure may be actively opened under the condition of an internal positive pressure or an external negative pressure, so that the liquid medicine in the liquid medicine container 40 may pass through the sealing structure after atomization, and thus be absorbed by a patient. The number of the liquid medicine containers 40 may be two, three, five, six, etc. The plurality of medical fluid containers 40 may be arranged in various manners, such as a circular arrangement or a square arrangement, around the circumference of the breathing tube 10.

It is understood that the concentration and the type of the liquid medicine required in different tests or different stages of the same test may be different, and the atomization device in the prior art needs manual replacement of the liquid medicine to perform the subsequent atomization.

The position sensor 52 is electrically connected to the main control module 20 so as to transmit the in-place information of the medical fluid container 40 to the main control module 20.

It can be understood that before starting the nebulizing function, it is necessary to ensure that the medical fluid containers 40 with the medical fluids required by the test are all prepared at the corresponding positions, for example, referring to fig. 4, this test requires the medical fluid in the medical fluid container No. 1 40 and the medical fluid in the medical fluid container No. 2 40, and the positions of the medical fluid container No. 1 40 and the medical fluid container No. 2 are located at the two ports on the right side, so before starting the test, it is necessary to confirm that the medical fluid containers No. 1 40 and No. 2 40 are in position by the two position detectors corresponding to the medical fluid containers No. 1 40 and No. 2 40, and then the nebulizing function can be started. Of course, the position sensor 52 may also be used to detect whether the corresponding interface has the medical fluid container 40 in place, and send the information of the medical fluid container 40 in place to the main control module 20, and then after determining the type of the test, determine the required medical fluids and allocate the medical fluids to the medical fluid container 40 in place.
