Description
Technical Field
The utility model relates to a medical auxiliary medical instrument technical field, concretely relates to medical atomizer of multichannel formula.
Background
The aerosol inhalation therapy is a direct administration method taking respiratory tract and lung as target organs, has the advantages of quick response, high local drug concentration, small dosage, convenient application, less systemic adverse reaction and the like, and becomes an important quality means for diseases related to the respiratory system. The aerosol inhalation therapy is to utilize high-speed oxygen flow to make the liquid medicine form mist, and then the mist is inhaled from the respiratory tract to achieve the purpose of therapy. Treating respiratory tract infection, and eliminating inflammation and edema. Relieving spasm. To thin the phlegm and help to dispel phlegm. Currently, there are four main categories of commonly used aerosol inhalation therapeutic drugs, which are:
(1) inhaled glucocorticoids, the representative drug of which is budesonide, are the most powerful local anti-inflammatory drugs for airways and are the first choice drugs for the treatment of asthmatic diseases at present. It exerts an anti-inflammatory effect by affecting cells and molecules necessary for inflammatory reactions, and belongs to the same class as beclomethasone dipropionate and fluticasone propionate.
(2) Short-acting beta 2 receptor agonists, which represent the drug terbutaline sulfate nebulised solution, are the most commonly used bronchodilators in the clinic. The method is characterized in that: has quick response and short maintenance time, and belongs to the same category, salbutamol is also used.
(3) The choline M receptor antagonist is commonly used as ipratropium bromide solution and compound ipratropium bromide solution. The action mechanism is as follows: the choline M receptor antagonist plays a role by competing with endogenous choline for muscarinic receptors (M receptors) on target cells, the M receptors have 5 subtypes, but only M1, M2 and M3 have definite physiological activities in respiratory tracts, and the M1 and M3 receptors are antagonized to relax bronchial smooth muscle and inhibit mucus hypersecretion, and the M2 receptor is antagonized to promote acetylcholine release from nerve endings to contract bronchi, thereby partially weakening the bronchorelaxation effect brought by antagonizing M1 and M3 receptors.
(4) The mucus dissolving agent, usually acetylcysteine, reduces the viscosity and viscosity of sputum and liquefies it to more easily cough the sputum. Can also inhibit the proliferation of mucus cells, play a role in scavenging oxygen free radicals in peripheral airways, inhibit the formation of bacterial biofilms, destroy formed biofilms and cooperate with antibiotics to realize effective antibiosis.
Among the above drugs, the specification of the inhalation budesonide suspension, pramipexole, clearly indicates that: for patients who use inhaled bronchodilators at the same time, it is recommended that the bronchodilators be administered prior to the administration of budesonide in order to increase the amount of inhaled budesonide that enters the bronchial tree. The two inhalants should be separated by several minutes.
According to 2018 edition "expert consensus on the emergency clinical application of aerosol inhalation therapy" and the instruction for promixomel (inhaled budesonide suspension), we generally follow the following principles if the two or three drugs are applied simultaneously: it is prepared by relieving bronchospasm (bronchodilator), relieving mucosal edema (inhaled glucocorticoid such as budesonide), and removing phlegm by administration of acetylcysteine (rich administration) to reduce phlegm viscosity and viscosity.
However, at present, clinically, when carrying out aerosol inhalation treatment on a patient, the required atomized medicine is usually added into a medicine cup of the atomizer at one time, and separate atomization of various medicines is not realized, and the currently clinically used atomizer usually has only one medicine adding port, if separate administration and atomization of various medicines are to be realized, a medical worker needs to add medicines for many times, needs to pay attention to the atomization time in real time so as to conveniently and timely add medicines, and has large workload and large labor intensity.
